I've watched ten of these damn videos and this is the first guy to explain it like I'm not trying to go to the moon. Kudos.
I like your opening statement reguarding a releif valve in the system. The local hydraulic shop here sold me a pump with a stuck compensator a while back. Defiantly cheap insurance!
I have a SCUBA tank compressor in my system that runs at 2500RPM and is 6cfm. Assuming the factory flow setting for the pump is set around 200psi and the pump can deliver 2.32ci per revolution. Can you please explain the relationship between the flow setting and the system pressure with reguards to compressor speed? When might I need to increase/decrease either flow or pressure. I also have a flow control before the motor to set the speed of the compressor. Thanks
Do you have a video on setting stand by pressure on a dfr style compensator
Thank you for your question, Curtis. I think you are talking about a load sensing pump? If so, yes, you can view it here - th-cam.com/video/1lUEsAp8b8g/w-d-xo.html
@@Gpmhydraulic yes that is correct, thanks
I usually see two pressure regulating valves near the pump. How do I tell which is the compensator and which is the pressure relief valve?
The compensator is typically attached directly to the pump while the relief valve is usually a separate component. In rare cases it may not be this way, the relief valve may also be integral to the pump, but in such a case, download the manufacturer manual from their website.
Why set comp.to 1200psi. Required only 200 psi.
Hi, Sundar - thanks for your question! In the absence of designer specifications, we recommend that the compensator be set at about 200 PSI above the pressure required to move the load. In the example, 1000 PSI was required to move the load, so we set the compensator at 1200 PSI. Hope this helps!
Thank you Sir
