How to significantly extend the life of the cylinder?

Introduction

As an important hydraulic component in the fields of engineering machinery, metallurgical equipment, shipbuilding equipment, etc., hydraulic cylinders are hydraulic actuators that convert hydraulic energy into mechanical energy and perform linear reciprocating motion. When using it to achieve reciprocating motion, the deceleration device can be eliminated and there is no transmission gap, so it is widely used in the hydraulic systems of various machines. However, if the hydraulic cylinder is not properly maintained during use, it will cause the need to constantly replace the hydraulic cylinder, so we should learn how to maintain the hydraulic cylinder on a daily basis.

The methods to extend the life of your cylinder

1. Regularly replace hydraulic oil

Hydraulic oil is the core medium of the hydraulic system, and its cleanliness directly affects the life of the cylinder. Hydraulic oil used for a long time will accumulate impurities, wear powder and oxides. These contaminants will accelerate the wear of the seals, resulting in reduced efficiency or even damage to the cylinder. Therefore, it is necessary to replace the hydraulic oil regularly. At the same time, installing a filter and cleaning the filter regularly can effectively remove impurities and keep the oil clean.

2. Regularly clean the inside of the cylinder

Dirt and impurities often accumulate inside the cylinder, seriously affecting the circulation and working efficiency of the hydraulic oil. Therefore, regular cleaning of the inside of the cylinder is an important part of maintaining the hydraulic cylinder. Cleaning agents and cleaning cloths can be used to clean the inside of the cylinder to ensure that it is clean and pollution-free.

3. Regularly check the seals

The seal is a very important component in the hydraulic cylinder, which plays a role in sealing and leak prevention. Check whether the seal is aging, hardening, cracking, etc., and replace the damaged seals in time to ensure the sealing performance of the hydraulic cylinder.

4. Reasonable use of the cylinder

Avoid overload and overpressure. Overload and overpressure will cause the cylinder to bear pressure beyond the design range, resulting in damage to parts. During use, the working pressure of the hydraulic system should be strictly controlled to avoid failure of the cylinder due to overload operation; control the operating speed. Under normal circumstances, the operating speed of the hydraulic cylinder should not exceed 2m/s. Too high a speed will accelerate the wear of parts. Reasonable control of the operating speed can effectively extend the service life of the cylinder.

5. Select high-quality parts

When selecting cylinders and their parts, original parts with reliable quality should be given priority. High-quality seals, oil seals, wear-resistant rings and other parts can not only improve the sealing performance of the cylinder, but also significantly extend its service life.

Conclusion

In short, regular replacement of hydraulic oil, cleaning of the inside of the cylinder, inspection of seals, and avoidance of overload operations are important steps to maintain the hydraulic cylinder and extend its life. Hydraulic cylinders are important power transmission components in mechanical equipment. Good maintenance of hydraulic cylinders can not only extend their life, but also ensure the normal operation of the hydraulic system, improve work efficiency, reduce failure rates, and ensure the safe operation of construction machinery.
