Waiting for your valuable suggestions please.

It could like 73lafuite suggested, it is simply running on high power for a short period of time. We at Makhoz have over nineteen years of solid experience supplying industry with precision fluid power components. It can serve two purposes as far as I can see: You can use a Fluke or similar to measure actual consumed power. This is an interesting topic that I am struggling to fully understand.

In this respect, the pumps is dynamically controlling flow, against changing pressure, to give constant power control. Red Flag This Post Please let us know here why this post is inappropriate.

It is only the fact that we make so many machines with this sort of control that means I can spot the difference. Number of Employees 11 to 25 People. Visit our website for more details. So in order to fully explain this circuit we need to know what the press is actually pressing.

So with a reduced flow the pump is allowed to go to a higher pressure thus keeping within the power limit. The main press cylinder fills via the prefill valve aa10vso can’t read its number. The pump flow will of course reduce when the pump power hits the power limit curve but the pump flow is not directly controlled by the proportional relief.

The proportional relief valve enables the cut off pressure to be set electronically. Pu,p this point, the pump will back off or increase its a10vwo to maintain the pressure drop over the orifice.

Without such an orifice the small pressure relief valve could become saturated and loose it’s function. The flow from the pump is directed to the a10vao, but the pump control remains independent of a10vos load at the actuators. The power control does what its name suggests.

The one just to the right of the pressure cut off and LS compensators on the drawing. On the machines I am responsible for, we use the main spool as the variable restriction and we have similar ;ump that responds to the changing pressure differential. The name plate on the pump is correct, it’s a DRS controller. The spool modulates to maintain the flow at a required level, say 65 lpm.

It’s a power limiting pump with a load sense compensator. Preference cookies enable a website to remember information that changes the way the website behaves or looks, like your preferred language or the region that you are in.

This in turn reduces the flow of the pump. The pump will swivel to max displacement. Correct me if I am wrong here Adrian. I have had a closer look and the following is what “should” be happening. The pump will then reduce its flow as the pressure increases further to remain approximately within the a0vso limit set. Usually but not always an increase in pressure will increase the flow.

Vane Pump in Mumbai. Is there a problem with the current operation or are you just trying to understand what’s happening? Call Send a quick message. On mobile machines with LS system the pressure out to cylinder from a certain directional control valve is sometimes limited to a lower setting on some Caterpillar machines also maybe?

As drawn the system gives Power, Pressure and Flow Control. Agreed, the pump supplier’s description refers to a pressure and flow controlled pump but the flow control has to be achieved by means of an external throttle valve not part of the pump control which would be a standard arrangement for a load sensing pump.

Unless we are going to make arrangements to visit the press and instrument it, we will just be making educated guesses at how it actually does function.

In this case it is a hydraulic press, accurate control of speed and position is not so important, the important thing is to control is pressure.
