Single acting hollow hydraulic jacks
New or long-term single-acting hollow hydraulic jacks, because there is more air in the cylinder, when the piston is used, the piston rod may show a slight jump phenomenon. The single acting hollow hydraulic jacks can be reciprocated 2-3 times without load to eliminate The air inside the cavity. Long-term idle jacks, because the seals do not work for a long time, causing the seals to harden, thus affecting the service life of the hydraulic jacks. Therefore, when the hydraulic jacks are not in use, the hydraulic jacks should be reciprocated 2-3 times per month.
Single acting hollow hydraulic jacks:
a) If there is a blanking phenomenon during working, first loosen the oil drain screw on the pump body, and then open vertically pump body and turn it down a few times, then tighten the oil drain screw to continue using.
b) When there is load, it is forbidden to remove the quick connector to avoid accidents and damage to the machine.
c) This machine uses oil as the medium. It is necessary to do the maintenance work of the oil and the machine to avoid fouling or oil leakage and affect the use effect.
