StoneCold,
Thank you for confirming what I am now starting to believe. Setting the relief valve on anything other than a test bench is poor planning. I will work on building a test bench.
As far as the 53GPM ever going fully through the relief valve, I doubt that would ever happen. We have...
You did interpret my description correctly, the relief valve is opening under normal operating conditions therefore not allowing all 53GPM from the pump to go to the equipment. However, I believe the relief valve isn't really set at 200psi. This is why: When we run the power unit and it is...
Hello,
I am learning as I go here, so please excuse any sign of ignorance.
I have designed and am now troubleshooting a lubrication power unit for a large piece of equipment. The power unit is designed to flow up to 53GPM of ISO 150 (750 SSU) weight oil. In this circuit is a large oil cooler...
Besides the obvious tensile and yield differences between 80-50 and 90-60 ASTM A148 steel, does anyone know of any other differences between these cast steels? Is 90-60 harder to weld? Is 80-50 less expensive? Anything else I should know so that I can choose the proper cast material for an...
