Self-locking jacks are mainly used in places where heavy loads are required for a long time. They can still support heavy objects when oil pressure is removed, and are safe and reliable. It can be used underwater, single action, load retraction, nut self-locking to make the load safer, especially in large projects, it is easy to operate control and hydraulic jack, designed with a safety pressure maintaining device, built-in pressure relief valve to prevent overload, to protect The jack is for safe operation. The connection of the device adopts a high-pressure hose and threaded joint connection, which has the advantages of quick use and overcomes the shortcomings of rapid traditional joint oil leakage. It is mainly used for equipment installation in various industries such as electric power, construction, machinery manufacturing, mining, railway bridge, shipbuilding, etc. Top disassembly work
Precautions:
a) If there is a blanking phenomenon during use, first loosen the oil drain screw on the pump body, and then open the pump body vertically and turn it down a few times, then tighten the oil drain screw to continue using.
b) When there is a 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.
d) New or long-term hydraulic jacks, because there is more air in the cylinder when the piston is used, the piston rod may show a slight jump phenomenon, and the hydraulic jack 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, cause 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.
