Calculating Hydraulic Pump Flow and Efficiency

[@JohnnyLawBMC]

Great video. You do a great job demonstrating and explaining this.

[@KletteTech]

Thanks

[@jamesgingin590]

Nice and simple to the point. Just what I needed.thank you

[@KletteTech]

Your welcome. Thanks for watching

[@vernonleeper1568]

Hello great video thanks for sharing. I have been following along and watching these. In the calculation for GPM, (4226.25/231=18.3) GPM and I trust you know what you're doing, what is or where does "231" come from for this ? I'm no math expert by a long shot but I just want to know if it is a standard/constant for figuring out this? Thank you.

[@busta960]

Yes it's a constant value That just converts 4226.25 from in^3 /min to gal/ min 1 gallon per min = 231 in^3 per min

[@matthewdublak2896]

231 cubic inches of volume in gallon

Can I use a similar principle to measure pump flow? I don't want to spend the money on a flow meter. If I connect a hydraulic motor to my hydraulic pump and using the displacement per revolution on the hydraulic motor and measuring how many rpms when running should make it possible to calculate the gpm of a hydraulic system. Would this work? I need to test my pump's gpm because I think it's not performing to specs.

[@KletteTech]

That is a an idea I have never thought of. There are couple factors that I would have to think about. But it would give you an idea if it is not running correctly. I would not put a load on the motor.

[@vivekjkumar5797]

If i can't get the theoretical flow rate for a gear pump. Is there a way to manually calculate the flow rate of the gear pump?

[@KletteTech]

Not that I know of. The problem is you don't know the volume per rotation. You can hook up a flow meter. That is about it

[@HarpreetSingh-dd5rw]

Sir, may i know what will be the flow value when we place pressure relief valve in the system.is flow value decreases of what we are getting from the pump? Thanks

[@Bmanny]

Thanks for the video, may I also know what are the other kind of approaches to increase the efficiency, apart from replacing the motor?

@Alden Ezra I really appreciate your reply. I got to the site through google and Im waiting for the hacking stuff atm. I see it takes quite some time so I will get back to you later with my results.

@Alden Ezra it did the trick and I now got access to my account again. I am so happy:D Thanks so much, you saved my ass :D

@Finn Callan glad I could help =)

super explanation and thanks for sharing

[@KletteTech]

You are welcome

[@noelpical2909]

where did you get the 231?

[@KletteTech]

That how many cubic inches are in a gallon

[@yeahitworks]

0:35 "How much a pump will move when it rotates 360deg"? What??? you answered the question in the same sentence. LOL.

[@oralwilliams5802]

where do you get the 231 from in the calculation

[@KletteTech]

That is the conversion from cubic inches to gallons.

Dear Sir............Example Problem I have a single acting hydraulic cylinder with a stroke of 300 mm, a bore of 18 mm and a rod of 10 mm if the press weight is 5 mm on the Piston Head what is the pressure.....Please explain the calculations

[@anbarasanstalin5998]

Constant of the formula to find GPM??

[@mohanmadarapu]

I need information how much KW required for using a single vane pump. And for a double vane pump? For example, For a single vane pump with 7KW power in, we will use 7KW motor. Second case, I have a double vane pump with port P1 7KW & port P2 10 KW. In this case, what is my motor capacity 7KW or 10 KW or 17KW(10+7)? Also for third case, i have bidirectional motor(two shaft ends). LH side end is a single vane pump with 5KW capacity. RH side double vane pump with P1-7KW & P2 10 KW. In this case how much capacity motor i have to select?

[@shamanking5195]

is 231 a constant ???where does the 231 come from ???

[@KletteTech]

It is how many cubic inches are in a liquid gallon

[@gulopac1]

Thanks, but, where 231 number come from?

[@KletteTech]

That is how you get to gallons

May I know sir Pump Impeller size(mm) to discharge water at high pressure for 5HP 8 Stage 3 phase submersible motor from 220feet at a voltage of 240v through 2inch pipe .

[@KletteTech]

Sachin, your questions is a dynamic fluid questions. I would feel uncomfortable answering the questions has that is not my main area of studies. My videos are for fluid power which is different than a dynamic pumps you are asking about.

[@bigbikejhonathan7173]

where can i get the given for 231

[@KletteTech]

It is the volume in a gallon of liquid.

[@b.m.dmakoporo463]

Thanks I can now hook up a flow meter to determine if my pump percentage is ok,70percent

[@KletteTech]

Yeah. 70 is good. what type of pump?

[@surendharsks3886]

how to cal efficiency if i dont know the actual gpm ?

[@KletteTech]

The actual GPM is the measured GPM that is read from the flow meter.

What is 231??

[@KletteTech]

That is how many cubic inches are in a gallon

[@WorshiptheTrinity]

Why 231? Where does that number come from?

[@KletteTech]

There is 231 cubic inches of liquid in 1 gallon of liquid. So, 231 is the constant used to convert cubic inches to gallons. Hope this helps!

[@WorshiptheTrinity]

@@KletteTech Yes thank you.

thank you sir

Your welcome!

[@rajeshjha5122]

Sir what is 231

[@KletteTech]

231 one is a constant when calculating a liquid volume to gallons. When you calculate out the volume per revolution, you then need to convert it to gallons to get to gallons per minute. Hope this helps. Any other questions please let me know.

[@nolanjones9378]

@@KletteTech 231 is the amount of cubic inches in a gallon.

HYDRAULIC PUMP. rpm = 180 / minute. ma pressure = 210 bar. displacement capacity = 27cc. ORBITAL MOTOR. max speed = 185 rpm. max torque = 290Nm. max output = 6.7hp. max preassure continue = 170bar. max intermitteent pressure = 200bar. max flow = 60 lpm. HAND VALVE. max pressure = 35mpa / 350bar. max flow = 80lpm. Do the items I have fit the machine? please advise the diameter of the hose. please help, sir. thanks.

Want to know about Power in real life. Rpm, hp,flow vs power demand. That's what I want to know.

[@hadiakbari740]

That’s not how efficiency of a pump is defined. It’s the ratio of theoretical power over actual power a pump is using to deliver any given flow rate at the actual head it’s delivering that flow rate. So, this is not correct at all.
