If the piston rod of the hydraulic cylinder is not treated in time after being pulled, the normal use will be affected if it is light, and the operation will not be possible if it is heavy. The repair methods we adopt are local polishing to repair light draw marks, welding and manual polishing to repair heavy draw marks. Zhuzhou Hydraulic cylinder Through quenching and tempering treatment, the comprehensive mechanical properties of the cylinder piston rod with good strength and toughness matching were obtained. Zhuzhou Hydraulic cylinder Price The purpose of surface hardening is to obtain high surface hardness to support the chromium plating layer on the surface, so as to improve the wear resistance and corrosion resistance of the piston rod.

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 Zhuzhou Hydraulic cylinder 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, Zhuzhou Hydraulic cylinder 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.

The speed ratio refers to the same flow (volume of liquid entering the hydraulic cylinder per unit time), Zhuzhou Hydraulic cylinder Price The ratio of the piston rod extension speed to the retraction speed. The calculation is equal to the inverse ratio of the large cavity area and the small cavity area of the cylinder. The speed ratio is related to the cylinder diameter and rod diameter of the oil cylinder.

There are many hydraulic components on construction machinery, and sufficient hydraulic oil is required. When the hydraulic oil needs to be replaced due to its deterioration after a long time of use, some people mistakenly believe that only drain the oil in the hydraulic cylinder and fill it with new hydraulic oil. However, there are still many old hydraulic oils left in the hydraulic oil pipe and hydraulic control valve, Zhuzhou Hydraulic cylinder When the equipment is used, the mixing of new and old oil will speed up the deterioration of new oil. The correct oil change procedure should first drain the hydraulic oil in the hydraulic cylinder, Zhuzhou Hydraulic cylinder Price After cleaning the hydraulic cylinder, add new hydraulic oil, remove the circuit header, start the engine and run at low speed to make the oil pump work.
