relationship between hydraulic pump and orbital motor

[pierop85]

Hello to all, I needed information, I have a diesel thermal motor from 7,5cv to which is connected an oil pump from 6cc, this pump connected to a distributor turns two orbital motors from 125, all makes move a vegetable machine, since I noticed that as an effort a little or for climbs or for wet ground tends to slow down and sometimes stop, but the heat engine does not yield, according to me I am not rape
Thank you.

from how you describe it, are the engines to be undersized for the couple they should develop.
you can try to increase the pressure at which the pump works, so that with the same engines you can develop a larger pair.
You should have a maximum pressure valve on the pump.

Given the virtually nonexistent data you provided, more so you can not help.

attention to the maximum pressure that your plant can endure, making a hot oil shower is not pleasant.

Hello thanks to the answer, the pressure I can calibrate from the distributor and currently it is on the 150bar, according to the technical boards of the engines, the max pressure of the input is 165, while the max pressure of the pump is 260 bar, what data do you need? that possibly place them

you need to calculate the maximum torque required by your application, just to start.

the "125" you write, without measuring unit, is the oil flow required for a ride of the engines? measuring units?

You wrote the unitary displacement of the pump, but what regime does it work? and the engines, what regime would you want them to turn?
How did you size the pipes? filters?

have you measured the actual pressure of the plant? put a pressure gauge on the drive circuit, just after the pump, just before the engines, and one on the return just after the engines, that already from that you can understand if the pump does its work correctly, if the tubes are sufficiently sized, and if the filter is clogged
