One of our Ball Mills keeps losing pressure on the high pressure pump. It will run fine when starting the Mill and suddenly after a while sometimes 1hrs the pumps will loose pressure. We have just grinded the journal and installed new white metal bearings. After startup this afternoon after about 1hrs the pumps low and high just lost pressure.

A hydraulic lift is a device for moving objects using force created by pressure on a liquid inside a cylinder that moves a piston upward. Incompressible oil is pumped into the cylinder, which forces the piston upward. When a valve opens to release the oil, the piston lowers by gravitational force. The principle for hydraulic lifts is based on ...

Use Pascal's Law: To calculate hydraulic pressure, apply Pascal's Law, which states that pressure is equal in all points of a confined fluid. The formula is: Pressure = Force / Area. Convert units if necessary: Ensure that the force and area are measured or expressed in consistent units (, Newtons for force and square metres for area).
