With the rapid development trend of the technology of The Times, the specification of tensioning jack is more and more common in the use of mechanical equipment in Our country, and the electric hydraulic jack has become everyone's favorite. So, the following is abnormal electric hydraulic jack, but on the surface and can not see where the problem is, how to do this? This is also the most headache for many people, if you can clearly identify the internal management of the common failure, do not disassemble, the problem can still not be handled, then you can consider disassembly. If the specifications of the vertical jack do not need to be removed and removed, it will cause great inconvenience, especially if the electric hydraulic jack is removed, the difficulty coefficient of technical workers is very large when repairing, which is time-consuming and laborious.

1: before removing the electro-hydraulic jack, we should loosen the speed regulating valve and other pressure, so that the pressure relief of the hydraulic control loop is close to zero pressure. Then disconnect the switching power supply, so that the hydraulic jack terminated operation, stop in a good disassembly part. Drain the hydraulic jack two chamber hydraulic oil, remove the cylinder head, before removing the thread adjustment, filling gasoline, placed for a period of time, gently knock the cylinder head, the thread vibration loose, can be removed.

2: the piston rod and piston rod components removed from the cylinder liner before removing the waste in the cylinder liner to carry out disassembly, can not be forced to get the piston rod from the cylinder head, to prevent waste damage to the cylinder hole. Disassembly, should avoid damage to the top thread of the piston rod, the oil hole thread and the piston rod and the surface of the piston rod, to prevent should not have random knocking and accidentally dropped on the road injuries and other conditions.

3: after the maintenance of the hydraulic jack into the installation, under normal circumstances all the sealing should be new, before the replacement should first find out the original sealing damage, in order to prevent the same reason to destroy the sealing again, all parts after careful cleaning can be invested in installation. After understanding the removal points of the hydraulic jack, I firmly believe that there will be great assistance for you in the maintenance and maintenance of the hydraulic jack.
