How to remove air in block machine hydraulic system

1. There is air in the hydraulic system of the china block making machine for sale.
Remedy: first check whether the oil pump suction pipe or suction port flange leaks. If there is no air leakage, it is likely that there is air in the pipe that has not been removed. It can be excluded by the following methods. (Turn on the cement brick oil pump, adjust the flow of the proportional valve to the maximum, adjust the pressure to 2-3MP, then remove the screw of the vent hole next to the flow rate and the screw of the vent hole next to the pressure, and slowly exhaust until it is eliminated clean.)

2. Cause of failure: The hydraulic oil level in the tank is too low.
Remedy: add hydraulic oil to the proper level.
