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. Zhanjiang Hydraulic station Through quenching and tempering treatment, the comprehensive mechanical properties of the cylinder piston rod with good strength and toughness matching were obtained. Zhanjiang Hydraulic station Manufacturer 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.
1. There are many factors that cause this problem. First, measure the pressure of the main system to see whether the pressure of the main system in the pressure holding state is consistent with the initial setting. Check the hydraulic oil and suction oil filter before measuring the pressure, Zhanjiang Hydraulic station Replace or clean it. Secondly, check the main overflow valve of the reversing control multi way valve to see if it is damaged or blocked by foreign matters, Zhanjiang Hydraulic station Manufacturer Clean it. If your pump is a gear pump, the problem should be minor in general. 2. Next, let's look at the traffic problem.
The hydraulic system is composed of various hydraulic components. All hydraulic components are organically connected into a complete hydraulic system by pipes, joints, integrated valve blocks and other parts. Therefore, whether the hydraulic pipeline is installed correctly Zhanjiang Hydraulic station Firm, reliable and neat will have an important impact on the working performance of the hydraulic system. Check the quality of pipes. Find out the pipe material Zhanjiang Hydraulic station Manufacturer Whether the size and quality meet the design requirements; Check whether there is serious flattening or bending on the appearance of the pipe, whether there is corrosion on the surface of the inner and outer walls of the pipe, whether there is crack on the outer wall and other defects.
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, Zhanjiang Hydraulic station 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, Zhanjiang Hydraulic station Manufacturer To ensure the service life of the hydraulic cylinder.
The diameter of the oil unloading hole of the hydraulic cylinder is too large, which directly affects the service life of the rubber seal ring on the piston. Because the piston moves back and forth, Zhanjiang Hydraulic station When the rubber seal ring on the piston passes through the oil discharge hole, the rubber's own elasticity expands to the oil discharge hole, and the oil discharge hole edge and the piston seal groove edge shear the rubber seal ring. At the same time, China has the advantages of strong market demand and low cost, and is expected to become the center of gravity of the world's hydraulic industry and oil cylinder industry in the future. The hydraulic cylinder is a very important part of the hydraulic machinery and plays an executive role in the entire hydraulic machinery, Zhanjiang Hydraulic station Manufacturer In the whole process, the hydraulic cylinder converts hydraulic energy into mechanical energy.
