Hydraulic cylinder When working, the production traction may be insufficient or the speed may decline. Many people do not understand what causes this series of accidents. At this time, we should carefully investigate one by one to find out the problem.

1) The piston fitting clearance is too large or the sealing device is damaged, resulting in internal leakage. The fit clearance shall be reduced and the seal shall be replaced.

2) The piston fit clearance is too small, the seal is too tight, and the movement resistance is increased. The fit clearance should be increased and the tightness of the seal should be adjusted.

3) The piston rod is bent, causing severe friction. The piston rod should be aligned.

4） Oil cylinder manufacturer The oil temperature rise in the hydraulic cylinder is too high and the viscosity drops, which increases the leakage; Or the piston and piston rod are stuck due to excessive impurities. Heat dissipation and cooling measures shall be taken to replace the oil.

5) The cylinder barrel is strained, causing internal leakage. The cylinder barrel shall be replaced.

6) Due to the frequent use of a certain section of the working stroke, the linearity of the inner diameter of the hydraulic cylinder is poor (there is a waist drum shape in some parts), resulting in the interconnection of high and low pressure oil of the hydraulic cylinder. The inner diameter of the hydraulic cylinder shall be bored and repaired, and the piston shall be equipped separately.

When we encounter problems at work, the first thing we should do is not complain about what, but find out the reasons, and then solve the problems. If we complain blindly, it will not only affect our own feelings and those around us, but also lead to a decline in the quality of work. But if you use the time of these complaints to find out the reasons and solve problems, you will only get more.

because Hydraulic cylinder manufacturer The equipment must bear a great pressure. The heavier the load, the greater its pressure will be Hydraulic cylinder The maintenance work is the whole Hydraulic system It is an important part of maintenance. The hydraulic cylinder is the heart of the hydraulic system. It is difficult to repair a heart problem, so the maintenance of the hydraulic cylinder should be careful.

How to maintain the hydraulic cylinder? The first is to prevent rust. Because the piston part of the hydraulic cylinder will extend out of the cylinder in the working state, it will naturally be corroded by oxide and acid gas, which requires us to coat it with a proper amount of grease for protection, so as to prevent the piston as a load-bearing component from being corroded and may break in the work. Then open the case and change the oil. Because after a long time of use, it is inevitable that foreign matters will enter the hydraulic cylinder, which will lead to increased friction during use. In addition, the hydraulic oil also has a certain service life. If the oil is not changed for a long time, the internal part of the hydraulic cylinder will be damaged or eroded.
