Single acting hollow (feedthrough) jack widely used in construction, bridge construction, road and railway construction, power station construction, equipment upgrade large tonnage jack, mechanical disassembly aspect, hollow jack with a pull-up, the center hole for the wire, steel and so on through the central space can be processed according to user needs, users can request the production of different specifications, different travel hollow jack, optional hydraulic jacks, single-acting manual pump. Hydraulic jack failure, but the surface analysis was not the problem, how do? If you can identify a problem is internal, not dismantling, the problem can not be resolved, then we can consider removal. If you do not disassemble and demolition will cause a lot of trouble, especially after the electric hydraulic jacks if disassembled, when skilled workers repair more difficult, more time-consuming. Today, as a manufacturer, to support you on the recipe separate hydraulic jacks, dismantling and assembling the issues to be aware. 1: Before removing the jack, you should loosen the relief valve regulator pistol, the hydraulic circuit pressure relief that is close to zero pressure. Then cut off the power supply, the hydraulic jack is stopped, parked in a good position to be removed. Let go of the two-chamber oil hydraulic jack, open head, be corrected before the demolition of thread, filling point kerosene, a period of time, tapping head Lu licensing of jack, the threaded vibrating loose, you can remove it. 2: The piston and rod assembly from the cylinder before dismantling the cylinder must first clean up the dirt and then disassembled, can not force the Pistons shot from the cylinder, so as not to damage the cylinder bore dirt. Demolition, should prevent damage to the top of the threaded rod, thread and port and piston rod surface, to avoid undue chaos beat and accidentally dropped on the ground 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 the original seal is broken, so as not to damage the seal again with the same reason, after all the parts before assembly into the carefully cleaned . To understand the hydraulic jacks after disassembly essentials, I believe you will be very helpful in the maintenance service or maintenance jack.
