Items to be checked when the speed of hydraulic cylinder slows down. 1. Where and what type of oil cylinder has been used for several years, Handan Hydraulic machinery What is the working pressure. You don't have any of these. How can I troubleshoot them for you. Check the lower seal if there is internal leakage. 2. It is likely that the internal working pressure of the oil cylinder has decreased. 3. Check whether the system is blocked, Handan Hydraulic machinery Price In addition, check whether the oil cylinder seal ring is damaged, and then check whether the piston rod is damaged. Basically, these aspects can identify the problem.

For the selection of hydraulic cylinder, the hydraulic cylinder will be selected according to the inner diameter, stroke, operating pressure and installation type during the selection of hydraulic cylinder. In fact, in addition to these, we should pay attention to the following points. First, when the hydraulic cylinder is loaded and then the actuating speed reaches a certain standard, Handan Hydraulic machinery Hydraulic cylinder with buffer device must be used. Or when the speed reaches a higher speed, a deceleration valve must be installed outside the hydraulic cylinder; Secondly, carefully select hydraulic oil and oil seal. Oil seals of different materials are selected for different hydraulic oils, Handan Hydraulic machinery Price To ensure the service life of the hydraulic cylinder.

Select the cylinder type correctly according to the working requirements and conditions. It is required that there is no impact phenomenon and impact noise when the cylinder reaches the end of the stroke; Cushion cylinder shall be selected; Light weight is required; It is required to select light cylinder; Handan Hydraulic machinery Narrow installation space and short stroke are required; It is required to select thin cylinder; It is required to have transverse load, and the cylinder with guide rod can be selected; High braking accuracy is required, and locking cylinder can be selected; It is not allowed to rotate the piston rod, and the cylinder with rod non rotation function can be selected; Handan Hydraulic machinery Price In corrosive environment, corrosion-resistant steel cylinders shall be selected.

The hydraulic cylinder is the actuating element that converts hydraulic energy into mechanical energy in the hydraulic system. The faults can be basically summarized as hydraulic cylinder misoperation Handan Hydraulic machinery Price It is unable to push the load and the piston slips or crawls. It is not uncommon for hydraulic cylinder failure to cause equipment shutdown. Therefore, Handan Hydraulic machinery Attention should be paid to the fault diagnosis, use and maintenance of hydraulic cylinder. The main reason for excessive wear of piston seals is that the speed control valve is improperly adjusted, resulting in excessive back pressure, improper installation of seals or contamination of hydraulic oil. Secondly, foreign matters enter during assembly and the quality of sealing materials is poor.
