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. Jilin Hydraulic press cylinder Through quenching and tempering treatment, the comprehensive mechanical properties of the cylinder piston rod with good strength and toughness matching were obtained. Jilin Hydraulic press cylinder manufactor 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 oil cylinder shall be assembled in a special workshop or assembly area, and the temperature shall be kept at 20~250C, Jilin Hydraulic press cylinder manufactor It shall be far away from the tuyere, dust and cutting area, with fresh air, no dust and no noise; Avoid direct glare. The assembly room shall be equipped with installation platform, sufficient working position apparatus, assembly turnover vehicle Jilin Hydraulic press cylinder Lifting and hoisting equipment and the following special basic equipment. a: Cylinder loader; b: Another cylinder cleaning machine is used to heat and clean another part; c: Pressure test equipment, used for pressure test of oil cylinder; d: The air duct is used to clean and dry the other parts after cleaning.
The valve core of the flow valve in the hydraulic cylinder is blocked, which is easy to cause the action failure of the hydraulic cylinder. We need to check whether there are pollutants in the oil in the hydraulic cylinder and whether the valve body is worn. It is necessary to check whether the piston rod seal is too tight, Jilin Hydraulic press cylinder Whether there are pollutants entering, whether the axis line is aligned, and whether the easily damaged components fail. If the pressure controlled by the hydraulic system is too low, the action of the hydraulic cylinder will also fail, Jilin Hydraulic press cylinder manufactor At this time, it is necessary to check the control pressure source to ensure that the pressure value is consistent with the specified value of the system.
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, Jilin Hydraulic press cylinder 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, Jilin Hydraulic press cylinder manufactor In the whole process, the hydraulic cylinder converts hydraulic energy into mechanical energy.
Fluid cleanliness. The cleanliness of the system oil will have a very important impact on the hydraulic cylinder. Hydraulic shock and vibration hydraulic cylinders will be affected by the performance of components, pipeline and medium characteristics, etc., which will be accompanied by hydraulic shock and vibration. Generally speaking, if the oil temperature is too high or too low, Jilin Hydraulic press cylinder manufactor Will have a great impact on the working efficiency of the hydraulic cylinder. If the oil temperature of the hydraulic cylinder is too high or too low, the physical and chemical properties of the medium will change, Jilin Hydraulic press cylinder As a result, the viscosity of the working medium decreases or the possibility of leakage increases.
Because the hydraulic cylinder must bear a great pressure, the heavier the load, the greater its pressure will be. Therefore, the maintenance of the hydraulic cylinder is the most important part of the maintenance of the entire hydraulic system. The hydraulic cylinder is the heart of the hydraulic system. It is difficult to repair a heart problem, so the maintenance of the hydraulic cylinder should be careful. first, Jilin Hydraulic press cylinder Rust prevention is required. Because the piston part of the hydraulic cylinder will extend out of the cylinder in the working state, it will naturally suffer from oxidation Jilin Hydraulic press cylinder manufactor The erosion of acid gas requires us to apply proper amount of grease to protect it.
