In the mid eighties, Igor Karassik wrote a three part series that described the down sides associated with off BEP operation. Part 1 explores radial thrust and temperature rise while Part 2 talks about internal recirculation and air binding. Part 3 discusses discharge recirculation and discharge bypasses. All are developed in a very understandable manner which is the aim of Pump Ed 101. These are scanned files plus the resolution will not be very good.

This tutorial explores both the most important preventive maintenance steps that influence pump and motor life. Part 1 talks about off BEP operation and outlines the way to determine the as built operating point. Part 2 investigates current unbalance as well as the corrective measures that ought to be taken.
Sometimes the flow and head of two pumps operating in paralle is just not what we expect that it is. This tutorial analyses the performance of identical and dissimilar pumps along with the effect in the system curve. Part 1 compares the pumps and Part 2 factors inside the system curve.
The pressure exerted with a colum of water is dependent upon its density and hight - - they have absolutely not even attempt to do with all the its volume. In this tutorial we go on a close look as of this paradox and offer various examples that support Pascals Principle.
In this turorial we explain the way a pipeline siphon works and offer several samples of how they can affect pump performance.

There are when pumps set up on lower flow applications require ability to pass the whole 3 spherical solid. Should you use a 4 pump and run to your left on the performance curve? Probably not. This tutoral provides options are numerous that will enhance pump life.
Vortex pumps have a very bad reputation from the engineering community because of the low hydraulic efficiency. It turns out that their lower maintenance usually substantially reduce overall operating costs though electrical costs can be slightly higher. This tutorial explains vortex action and offers several examples that report why such type of pump might be a more sensible choice.

This tutorial requires a different method of pump selection for VFD operation. Part 1 addresses constant pressurevariable flow while Part 2 addresses variable pressurevariable flow. Part 3 adds an elevation or constant pressure section variable pressurevariable flow.
Back from the old days level control had absolutely nothing to do with saving energy. In fact that it was often a necessary evil. With the advent with the VFD you could be able to achieve relatively constant flows and reduce the power required. This tutorial investigates the chances.
If the aim of your VFD application is usually to reduce energy consumption, you should do a careful comparison between VFD and constant speed operation. This tutorial works on the constant pressure application to inform you the proper way to accomplish that comparison.
VFDs helps to reduce energy consumption by getting a pump to perform at the duty point necessary for system and it may change that duty time real time. But they offer other advantages that will often justify their use even when pump speed isn't varied. This tutorial explores those other advantages.
We are very mindful that a VFD varies the regularity seen by a power motor. That is the way it varies the motor speed. But, were you aware that it must also vary the voltage? If it would not, the magnetic field created by the stator would become saturated and torque would become unreliable. This tutorial explains the voltshertz relationship that must definitely be maintained with the VFD.
The vibration that occurs in the pumping system caused by resonance just isn't a great thing. Resonance arrises any time a variable speed pump reaches a crucial speed. It turns out that the very first or lowest critical speed can easily be calculated from simple data provided through the manufacturer. This tutorial explores resonant frequency and shows tips on how to calculate the interest rate that causes it.

PPPA provides both through the line and variable speed analysis up to eight pumps running in parallel. See my December, 2013 Pumps Systems article for any full description of the capabilities.
The 2013 version of my field test calculator allows detailed testing of pumps from the field. There are four different tabs that directly address testing of above ground centrifugals suction discharge gauge method, submersible wastewater discharge gauge method and lineshaft turbines discharge gauge method. After entering the desired data the calculator will calculate velocity, velocity head, TDH, average voltage, average current, unbalanced voltage and current, water HP, test point HP, pump efficiency along with the cost per 1000 gallons pumped. If multiple points are tested an H/Q test curve is generated automatically onpage 3. All equations used by calculations are shown for the spreadsheet. Complete instructions are included. See my Jan 2011 and May 2014 Pumps Systems articles for additional information.
This simple calculator enables you to enter the motor OD and casing ID for just a submersible well pump application. It then calculates the flow velocity in the evening motor, the effective flow ID plus the friction per motor foot.
The mains voltage also fluctuates and isn't a clean sinewave. If you were to look on the line voltage over a scope, it'll be distorted with a lot of high frequency noise superimposed within the signal. All with this adds around increased vibration and noise through the motor that may be coupled into your cartridge and heard from the playback of LPs.
Even should the line frequency is precisely 60Hz, the motor could possibly be at the correct speed but that doesnt guarantee how the platter is on speed. Variables like pulley tolerances, belt tension, diameter and slippage can all modify the actual speed with the record. This is why some pulleys are tapered so as to allow the user to the speed with the platter, however, this adjustment mechanism is significantly too coarse.
A synthesized Power Supply much like the Falcon or Eagle offers a clean, stable signal to push the motor. The frequency is crystal controlled so that it does not fluctuate just like the wall power can. The signal is often a pure sine wave with 0.5% distortion and which has no noise or high frequency artifacts. To compensate for variables like pulley dimensions and belt tension or slippage, the PSU frequency is adjustable in 0.01RPM steps to precisely dial inside platter speed. The result is often a more dynamic playback, with wider and deeper sound stage, with reduced pitch variance especially noticeable on single notes played on the piano and other string instrument with long sustains. Bass response becomes tighter with a lot more impact and highs are clearer.
It is universally accepted that accurate platter speed is very important for high fidelity playback of records. In the past, strobes are actually used because the standard for setting platter speed. The problem with strobe disks is because lack resolution. A platter speed error of 0.01 RPM means the extra edge of a 12 platter will drift 0.011 concerning the thickness of card stock paper per revolution which will take 1.8 seconds at 33.3 RPM. If the strobe disk can be a smaller diameter than 12, the drift will likely be proportionately smaller. This is very difficult to see using the naked eye, so it needs to be tracked for minutes after which calculated by dividing the entire drift through the elapsed time. This is time intensive and cannot be practiced while listening to your record. The RoadRunner tach creates a digital readout on the speed within 2 revs while listening towards the music and updates on every revolution afterwards with 3 decimal places of resolution by using a temperature compensated crystal reference that may be accurate to 0.00025% 2.5PPM.
Belt drive turntables are afflicted by speed accuracy as a result of tolerances in pulley and belt dimensions, belt tension and slippage, needle drag along with other variables that happen to be difficult to master or eliminate. Even if the interest rate is precisely dialed in employing a synthesized energy, the table is vulnerable to long term speed drift because the belt and bearing oil warm-up over time. This is especially noticeable when when switching to and fro between 33.3 RPM and 45 RPM records.
By connecting the output in the tachometer on the input on the Falcon or Eagle strength, the rate can be compensated over the extended to correct minute speed drift before it is audible. By utilizing the feedback between tach and PSU, a belt drive turntable can provide the velocity accuracy of your Direct Drive turntable, while still providing greater isolation of motor vibration through an elastic drive mechanism.
The Falcon PSU was created to work with turntables that utilize an AC synchronous motor that draw 5 Watts or less. It will function with AC induction motors once they are below 5W, but the interest rate stability are not as consistent similar to a synchronous motor. It will not use DC motors or tables that have an internal AC supply ie VPI Traveler, Linn LP12 with Valhalla energy, etc. without bypassing taking off the internal AC supply.
The output with the Falcon is 115VAC nominal adjustable to 85VAC but could power lower voltage tables by plugging the wall adapter for your motor into your output from the Falcon.
To makes use of the Falcon which has a 220VAC motor, you will need to supply a proper low power intensify transformer for instance a travel converter
The Eagle PSU was designed to work with turntables that utilize an AC synchronous motor that draw 15 Watts or less. It will function with AC induction motors after they are lower than 15W, but the velocity stability are not as consistent like with a synchronous motor. It will not use DC motors or tables that have an internal AC supply ie VPI Traveler, Linn LP12 with Valhalla power, etc. without bypassing taking off the internal AC supply.
The output with the Eagle is jumper selectable for 115/230VAC nominal adjustable right down to 85/170VAC but sometimes power lower voltage tables by plugging the wall adapter for that motor in to the output on the Eagle.
The RoadRunner Tachometer will assist any turntable, provided there's enough clearance for your sensor PCB/magnet, which requires no less than 0.25 6mm between plinth and platter.
The Falcon/Eagle PSU as well as the RoadRunner Tach might be used stand-alone or together. You can utilize the Falcon/Eagle PSU to power the motor and utilize a strobe or some other device to help with setting the pace. The RoadRunner could be used from the place of any strobe, with or with no Falcon/Eagle PSU. They can be used together, yet not connected make use of the PSU to power the motor, monitor the interest rate with the RoadRunner and manually set the rate on the PSU.
If connected together, the velocity is automatically adjusted from the PSU, according to information received in the RoadRunner.
The Falcon PSU comes that has a universal input 100-260VAC wall adapter and contains a NEMA 5-15 North American 3 prong socket around the end of your 3ft cable with the output. It is usually ordered through an IEC 60320-C13 output socket that plugs right into some turntables or stand-alone motor assemblies ie VPI.
The Eagle PSU comes using the control unit, the amplifier, a universal input 100-260VAC wall adapter w/6ft power cable, a 6ft cable that connects the control unit to your amplifier and it has a NEMA 5-15 North American 3 prong socket for the front panel in the amplifier for your output.
The RoadRunner comes having a universal input 100-260VAC wall adapter, sensor assembly, miniature magnet that attaches to your platter and cables which are between the sensor/tachometer and involving the PSU/tachometer.
All from the products have universal input 100-260VAC 50/60Hz wall adpaters that power them. The output in the Falcon PSU is 115VAC only therefore it would demand a low power boost transformer travel converter they are driving a 220VAC motor. The Eagle is jumper selectable for 115VAC/230VAC output and may drive a 220VAC motor without having a converter
There isn't difference from the motor that work well from a 50Hz or 60Hz line voltage, but they also will spin at different speeds because with the drive frequency, therefore they've got different sized pulleys to guarantee the platter spins for the correct speed. Both the Falcon and Eagle are front panel programmable to assist either 50Hz or 60Hz pulleys.
The Falcon and Eagle PSU units will use 500/600 RPM along with 250/300 RPM motors subject towards the power requirements above and as long since the motor is fitted using the correct pulley. A 250/300 RPM motor still takes a 50/60Hz frequency supply, but turns at half the interest rate of a 500/600 RPM motor therefore the pulley should be twice as large.
The Falcon is front panel programmable to help either the tiny or large pulley spindle, but tests have established the best performance is obtained with all the smaller 33.3 RPM spindle and it is shipped in the factory on this selection enabled.
The Eagle PSU runs on the transformer within the output stage which is restricted to certain output frequencies. Therefore the Eagle is simply programmable for 50Hz small spindle or 60Hz small spindle along with the belt MUST be installed for the small spindle on the motor pulley.
The Falcon is amazing and can be a very real upgrade for almost any low to mid-range VPI table. I would recommend the Falcon for virtually every Scout, Scout JR, HW-19, Nomad, original traveler without power source. etc., you may really hear the gap. Nice job!
The Eagle has landed! After with all the Roadrunner to evaluate my Scoutmaster table speed for that last month, I finally chose to bite the bullet and go for your Eagle PSU. Without the PSU, it had been quite evident that speed fluctuations were/are common that has a belt driven stand-alone motor setup. Move the motor a hair, as well as the speed changes. Clean and powder the belt, as well as the speed changes. Im sure that other things including bearing grease, tracking, etc., also help with speed changes. Even when I zeroed inside the speed perfectly, because of the time one side in the record was over, the pace had fluctuated above or below the 33.3 or 45 rpm setting. It was minor, going between say 33.000 and 33.375, and thats once you have the distance relating to the motor and platter right on in the start of any listening session. I was sick and tired of having to check and adjust for speed continuously.
In comes the Eagle PSU. Well made, dual box design to manage most high power motors around 15 watts. Easy setup then I pushed the button and watched it go to be effective. After eight seconds, the roadrunner indicated a speed which is between 33.332 and 33.336. And it stays in that area with the entire side! Love it. No more measuring and adjusting speed. Fully automatic.
Now to the sound. Did I hear a difference while using Eagle vs the Scoutmaster going directly on the wall? I place on my Classic Records 45 rpm of Crosby, Stills and Nash self titled pressing. I played Helplessly Hoping. I listened twice fully through also it sounded great. I then took the Eagle out on the chain and listened again. Heres in which you notice an improvement. Soundstage width had shrunken. Clarity of voices had also diminished somewhat, everything being somewhat homogenized together instead of separate entities from the soundstage. This happened record after record. Once you hear the clarity of separation while using PSU available, you will not want to take it out. I can only think that this is the result in the motor ramp down voltage following your motor has got the table up to take care of speed. Less motor vibration, I would imagine. Of course, notes like those coming coming from a piano had fantastic decay without the need of speed fluctuations noticeable. All in every, Im happy at what I am hearing. I cant comment about the SDS from VPI as I never owned one. But the sound the following is good and I never have to concern yourself with checking speed again.
Just got my Phoenix Engineering Falcon and RoadRunner; they get my highest recommendation. Excellent build, working perfectly and is usually adjusted to almost anything with higher resolution. I think it is the only controller wonderful these features. The only thing is that it can output only 110V, so with the rest of us on 220V, you need a boost transformer. I built one inch an outside box by having an A/C voltage indicator so I can monitor it, as output voltage is adjustable. Sound improved considerably. A big stepup for my system. Also thanks a lot for your excellent support.
I recently purchased the Phoenix Engineering Falcon and RoadRunner PS and Tachometer for my VPI Classic. The Falcon replaced the Music Hall Cruise Control 2.0 that I had been using for my VPI. The Cruise Control had one large problem that drove me crazy and thats the reality that in 45 RPM it could not build speed alone. I would were forced to give the platter a solid push to get it nearly speed. The Cruise Control was capable to keep the spin when the platter was approximately speed. Even when collecting the LP to alter sides the platter would decrease without the CC being in a position to spin it without assistance. I suspect the CC is severely under powered for your VPI Classic and as a result will not provide enough power to your motor.
In comes the PSU/Tachometer set from Phoenix Engineering. The first thing you see is how small the unit are. If you combine the 2 boxes they can be actually considerably smaller compared to the Music Hall CC. Both are powered by a wall wart power. The one who comes together with the Falcon PS is multi voltage and will continue to work in both 110v and 220v countries. The one who comes with all the RoadRunner is 110v only but any 9v DC energy will work which are readily available. I used a strength I had scattered about the house since I needed one that operates at 220v. I have not a clue why Phoenix Engineering decide to use a 100v only wall wart using the RoadRunner nevertheless its not a big problem.
Setting in the Falcon and RoadRunner became a snap and I was operational with in 45 minutes, 20 min of which was selecting a place to attach the little magnet for the platter and another a quarter-hour to route the cables. When I say small magnet I mean SMALL. You can lose it within a second if you're not careful. When both units will work together there can be a cable that attaches the 2 together and continuous speed feedback through the RoadRunner for the Falcon. This enables the Falcon to fix speed without having user intervention. Its amazing how great this method works. Out on the box once the Falcon was set to 33.3 RPM the VPI involved 0.8 RPM slow. As soon as I connected the cable between your two units speed was gradually corrected and after 6 roughly rotations was with in 0.004 RPM from the desired 33.3 RPM speed. You can actually understand the RoadRunner constantly correcting speed as a reaction to changing stylus drag during playback. The increments can be extremely slow and are also in no chance noticeable.
Now towards the The biggest noticeable improvement when I moved to your VPI Classic was its speed stability. Before obtaining the VPI I never gave an excessive amount of thought towards the effects of speed stability nevertheless the VPI quickly managed to make it clear how important this is good for micro dynamics, focus, bass weight and solidity of soundstage image. When I used the Music Hall CC I didn't notice any significant difference in sound. I used it mainly to the convenience of speed change. I do not like to have to touch the belt whenever I wish to change speeds. The Phoenix Engineering duo the takes mtss is a clear step of progress with best of all micro dynamics, weight while keeping focused. A great feature with the Falcon PS is that it is able to reduce the voltage to your motor as soon as the motor is around speed thereby reduce motor vibrations. After setting this feature to scale back the voltage to 85v in the standard 110v there became a clear decline in rumble that resulted in a very lower noise floor. Putting the stylus with a blank record, I were required to turn the amount up 4-6 DB higher in this little preamp to see any noise from your stylus. This is really impressive!
Overall the when utilizing Falcon/RoadRunner duo the sound gains in numerous ways it had been an eye/ear opener. I have many Ella Fitzgerald and Billie Holiday 45 RPM classics. The vocals on these recording were so lifelike its breathtaking. You can hear every nuance of the voice, every breath and diction. Makes you appreciate how talented Ella and Billie are. Listening to Count Basie big band, the soundstage wasn't this expansive. I might be imagining things but I think SS depth has improved somewhat. Great piano recordings like the Oscar Peterson Trio We Get Requests sound absolutely stunning. I have this recording over a 33 RPM remaster plus the piano sounds more lifelike than previously.
All in every as you can tell I am extremely happy together with the Phoenix Engineering duo. I have never tried the VPI SDS strength but at a lot less than half the retail price this duo does an extraordinary job along with the advantage of automatic realtime speed correction.
The Phoenix- Engineering RoadRunner Turntable Tachometer arrived yesterday. It is really a very compact digital display unit and an even smaller sensor and magnet familiar with trigger and have the rotation data. The RoadRunner digital display is sufficiently small to be placed almost anywhere. In my case I was capable to tuck it around the shelf beneath the Boos maple butcher board that sits on four Symposium Fat Padz with my Michell Gyro SE turntable at the top.
Setting in the RoadRunner tachometer is usually easy or difficult based within the design of your turntable. As it proved the Michell Gyro SE became a challenge considering that the platter is just not close towards the bearing support frame. There was absolutely no way to place the magnet which induces the sensor for the bottom in the platter and have absolutely it work. The magnet must pass within 1/8 or less with the sensor to operate. I was uncertain about where you can locate the sensor therefore, the magnet could pass from the sensor as close as necessary. I found themselves attaching the magnet to your outer bottom edge of one in the brass weights in the platter and attaching the sensor circuit board towards the inside rear suspension spring cover. The sticky tape about the back in the sensor board got easy to mount once I determined an area that would work. From the front with the turntable you cannot start to see the sensor board and also you would only spot the magnet should you knew it absolutely was there once the platter is rotating. The rest in the RoadRunner tachometer installation was easy, just plug inside wall-wart energy transformer and plug the cable from your sensor board on the back in the digital tachometer.
Once all from the connections were made I turned within the RoadRunner tachometer with all the small white push-button within the rear with the tachometer enclosure. The display illuminates with dashes. If no rotation is sensed, the display will shut off after a period of energy. Once the turntable platter begins rotating and a couple of full revolutions have at night magnetic sensor the digital read out displays the platter rotation speed. Since my Michell Gyro SE is powered using the Michell Never Connected power source I am in a position to adjust the rotation speed having an adjustment screw for the power supply. I was surprised to find out my initial speed was 31.76 RPM. I adjusted the velocity as close as I could to 33.33 RPM. What I then discovered was their can be a speed difference with and without worrying about phono cartridge tracking an archive. As it been found, the weight with the tracking force and stylus friction of my Ortofon Cadenza Black cartridge reduced the platter speed approximately 0.07 to 0.08 RPM. I fine tuned the velocity adjustment around the Michell Never Connected power source while the cartridge tracked an album to be sure playback rotation was as accurate as you possibly can. This resulted within a typical platter speed that had been higher than 33.33 RPM if the cartridge had not been tracking an increasing groove.
The RoadRunner turntable tachometer is usually a very useful tool for checking platter rotation accuracy. Having a power source that allows speed rotation adjustment is often a definite plus. Additionally, the RoadRunner tachometer will also be paired with all the Phoenix- Engineering Falcon PSU power source unit when your turntable runs on the 120 volt AC synchronous motor. With the RoadRunner tachometer connected for the Falcon PSU, the tachometer rotation information governs the Flacon PSU to control the velocity you select.
When I first saw photos and read regarding the RoadRunner tachometer initially my impression caused me to think it had been a toy. After installing the RoadRunner tachometer and also using it my impression has evolved. It is usually a well conceived generating tool for your vinyl enthusiast who's concerned with getting the very best speed accuracy from your turntable. Even without a power source that allows speed adjustment the RoadRunner tachometer will still supply you with accurate platter speed information. Using the RoadRunner tachometer with the turntable is really a great approach to increase your enjoyment and help the quality of vinyl playback. I like it.
I installed the RoadRunner in this little ClearAudio Innovation Wood today. Talk about a secret slick install, appears to be this was made to order for this table.

Actually it refers to your diametrical pitch on the pulleys.
Diametrical pitch is commonly a term used in gear measurements. But the same principles may also be applied to pulleys. The measurement is the place where the center from the belt contacts both sides on the V within the pulley. Also known because pitch diameter from the pulley.
