How does a 315 ton hydraulic press prevent air from entering the hydraulic system?
a. Connect all the oil return pipes below the liquid level of the fuel tank, and cut the oil return pipe mouth into oblique sections to reduce the vortex or agitation caused by the liquid flow.
b. The suction port of the pump should be far away from the oil return pipe to ensure that the excess air in the oil can escape in time during the time interval from the oil return of the system to the re-suction of the pump.
c. Use the exhaust valve properly.
d. Make sure the system is completely sealed (especially the hydraulic pump suction line) to prevent air from being sucked in.
e. In order to prevent various foreign impurities from entering the system, the leaked oil is not allowed to flow directly back to the fuel tank; an air filter must be installed at the vent port of the fuel tank; the system must be thoroughly cleaned when replacing the hydraulic oil of the hydraulic machine; the new oil added must be filtered.
f. Try to avoid using zinc, lead, copper and other materials that can play a catalytic role in oil. The inner surface of the oil tank is treated with pickling and phosphating, and the oil resistance of the sealing material is better.
g. The quality of the hydraulic oil of the hydraulic press should be checked regularly according to the conditions of use.
h. The liquid level should be checked regularly. If it is lower than the lower limit of the oil level gauge, refueling must be added to the specified liquid level. The hydraulic oil added must be of the same brand, otherwise the oil quality will deteriorate.
