Pressure handle: the handle of the process is a pressure pump convert mechanical energy into hydraulic energy to do work process. At this high pressure plunger work, low pressure valve is closed, the oil flows into the pipe from the valve block hydraulic compactor repair quote, thus promoting the hydraulic cylinders acting. When the pressure continues to rise more than the rated pressure 70MPa, the internal high-pressure pump valve is opened, the oil from the oil return pipe from the high-pressure valve repair hydraulic roller overflow, thus ensuring the supply pressure is always kept at 70MPa. We usually say here is the safety valve high pressure valve. Safety valve is working to ensure that the necessary components does not exceed the load pump. Oil pump liquid viscosity oil can repair 1-8 ° E clean neutral mineral oil or vegetable oil roller hydraulic repair company, operating temperature, preferably at 10-50 ℃. To ensure the normal operation of the oil pump repairs: suction pipe port should leave 5 cm above the bottom of the container to prevent stolen goods being inhaled. Suction height preferably not more than 1 m, the suction pipe length should not exceed 4 meters, or less if found not absorbing oil, check pump rotation direction is correct, whether the pipeline flow channel, the suction pipe for leaks. Pump is equipped with three-phase motors, single-phase motors or for users to choose.
