Hydraulic jack failure, but the surface was not the problem analysis jack, how to do? If you can identify a problem internally, without removing 320 jack, the problem can not be resolved, then we can consider the demolition. If you do not need to be demolished and removed the single jack cause a lot of trouble, especially after the electric hydraulic jack if disassembled, when skilled workers repair more difficult, time-consuming and laborious. Today, as a manufacturer, came to support you the recipe, disassembly and assembly problems to note. 1: Before removing the jack, you should loosen the relief valve and other regulating handguns, the hydraulic circuit pressure relief that is close to zero pressure. Then cut off the power, the hydraulic jack jack thin stopped, parked in a good position to be removed. Let go of the two-chamber hydraulic jack oil, open head, before the demolition of the first amendment to the thread, filling point kerosene, place for some time, gently tap the head, so that the vibration loose thread, you can remove it. 2: The piston and rod assembly from the cylinder before the demolition of the first cylinder to clean dirt and then disassemble, can not be forced to play from the piston cylinder, so as not to damage the cylinder bore dirt. Demolition, should prevent damage to the top of the threaded rod, screw and piston oil port and piston surface, to avoid undue chaos beat off the ground and accidentally bumps and so on. 3: After repairs hydraulic jacks into the assembly, in principle, all seals should all the new ones, new ones should be preceded by the identification of the reasons for the original seal is broken, so as not to damage the seal again with the same reason, after all the parts before assembly into carefully cleaned . In the understanding of hydraulic jacks after disassembly essentials, I believe you will be very helpful in the maintenance or repair and maintenance jack. (1) dual-circuit, the return speed, high work efficiency. (2) applies to the top pressure or anti-pull effect. (3) the outer ring and plunger threads and base threaded holes for easy installation. (4) movable saddle, work to protect the plunger. (5) internal safety valve to prevent accidental overloading. (6) dust ring to reduce pollution and extend the life of a single hydraulic cylinder jack, jack Jinghai Lu Lu Hydraulic power is provided by a hydraulic machinery plant in Texas.
