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, Qingyuan Oil cylinder 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, Qingyuan Oil cylinder 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.
Before removing the hydraulic cylinder, depressurize the hydraulic circuit. Otherwise, when the oil pipe joint connected with the oil cylinder is loosened, Qingyuan Oil cylinder The high-pressure oil in the circuit will be ejected rapidly. When the hydraulic circuit is depressurized, first loosen the hand wheel or pressure regulating screw at the overflow valve to unload the pressure oil, and then cut off the power supply or power source to stop the hydraulic device. During unloading, prevent damage to the thread at the top of the piston rod, the thread at the oil port, the surface of the piston rod, the inner wall of the cylinder liner, etc. Qingyuan Oil cylinder Price In order to prevent the piston rod and other slender parts from bending or deformation, the skid shall be used to support and balance during placement.
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. Qingyuan Oil cylinder Through quenching and tempering treatment, the comprehensive mechanical properties of the cylinder piston rod with good strength and toughness matching were obtained. Qingyuan Oil 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.
Two way hydraulic cylinder, which is one of the hydraulic cylinders, is a common and commonly used type of hydraulic cylinder. Therefore, Qingyuan Oil cylinder Price It is necessary to have a correct understanding of this kind of hydraulic cylinder and have a certain understanding, so that we can know how to use it reasonably and make full use of it. This kind of hydraulic cylinder has corresponding operation regulations and maintenance regulations, because it is in the hydraulic cylinder category. In addition, Qingyuan Oil cylinder It is necessary to have a clear and comprehensive understanding of its operation and maintenance procedures. The symptom of strain and wear is that the lifting speed of the equipment is relatively slow, accompanied by self subsidence.
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, Qingyuan Oil cylinder 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, Qingyuan Oil cylinder Price To ensure the service life of the hydraulic cylinder.
The connection between the oil cylinder and the actuator and the connection between the oil cylinder and the oil pipe cannot be the same, because there must be some differences between the connection between the oil cylinder and different products. In addition, during the use of the oil cylinder, it is necessary to avoid scratches, Qingyuan Oil cylinder Because if this problem occurs, it will affect the normal use of the oil cylinder. At present, there is no software for designing hydraulic cylinders, but there are design standards for hydraulic cylinders, and it is necessary to design hydraulic cylinders according to these standards. So far, Qingyuan Oil cylinder Price There is no software for designing hydraulic cylinders, but there are design standards for hydraulic cylinders.
