Everyone should be familiar with the jack, which is a kind of equipment used for lifting, and there are many types of jacks now, and hydraulic jacks are one of them. The so-called hydraulic jack is a combination of hydraulic technology, its lifting force is greater, can act on some relatively large heavy objects, can lift heavy objects smoothly, is a very useful equipment. Nowadays, no matter what industry and occasion it is, you can see the figure of hydraulic jacks, especially in some construction sites, when building bridges and lifting some relatively large mechanical equipment, this kind of jack needs to be used, which can be said to be very wide-ranging.

Hydraulic jack is originally a relatively complex mechanical equipment, and there are many places to pay attention to when using it, otherwise it is likely to cause damage to the hydraulic jack. If it is not used properly, or the maintenance is not enough, the hydraulic jack will definitely fail, and when repairing the hydraulic jack, you must first accept the following professional guidance before operating.

Stay informed

Patiently listen to user feedback, figure out the specific problems in use, because we can not guarantee the professionalism of users, we can consult possible problems in plain language, only in this way can we get complete maintenance information.

Wash surfaces

First of all, we need to disassemble the hydraulic jack, because the inside may be contaminated with some other substances during use, there may be some metal powder, sediment, debris, etc. inside the machine, and the inside of the hydraulic jack must be kept clean first. In fact, most of the time the hydraulic jack fails because there are too many impurities in it, so we also need to clean it strictly after disassembly.

Check the appearance

By checking the surface of the cleaned exterior surface, it can be clearly seen whether there is damage to the parts, and the cylinder strain and piston rod strain caused by misoperation such as excessive jacking and irregular jacking can be clearly observed.

Replacement parts

Due to oil leakage, lack of pressure caused by the sealing ring, we can replace the original sealing ring. Since the sealing ring will deteriorate after a long period of use, we can obtain it by consulting the factory.

After the above learning, we can repair the general small problems, and if we encounter mechanical hard damage problems, we need to return to the factory for testing. Well, that's all there are a few points about the repair of hydraulic jacks.
