Before removing the hydraulic cylinder, depressurize the hydraulic circuit. Otherwise, when the oil pipe joint connected with the oil cylinder is loosened, Jiangmen Hydraulic equipment 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. Jiangmen Hydraulic equipment 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. Jiangmen Hydraulic equipment Through quenching and tempering treatment, the comprehensive mechanical properties of the cylinder piston rod with good strength and toughness matching were obtained. Jiangmen Hydraulic equipment 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 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, Jiangmen Hydraulic equipment 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, Jiangmen Hydraulic equipment Price In the whole process, the hydraulic cylinder converts hydraulic energy into mechanical energy.
Because the hydraulic cylinder has to bear a great pressure, the heavier the load, the greater its pressure will be. Therefore, the maintenance of the hydraulic cylinder is an important part of the maintenance of the entire hydraulic system. The hydraulic cylinder is the heart of the hydraulic system, Jiangmen Hydraulic equipment It is difficult to repair the heart problem, so the maintenance of the hydraulic cylinder should be careful. First, rust prevention. Because the piston part of the hydraulic cylinder will extend the cylinder in the working state, Jiangmen Hydraulic equipment Price Naturally, it will be corroded by oxide and acid gas, which requires us to coat it with proper grease for protection.
Compared with mechanical transmission, hydraulic cylinder transmission is a new transmission form. Hydraulic transmission has a history of more than 200 years since the birth of hydraulic press, but hydraulic transmission has been going on for many years. Especially after the 1960s, with the development of atomic energy science, space and hydraulic technology, Jiangmen Hydraulic equipment It permeates all fields of the national economy, including agricultural machinery, automobiles, light textile, shipbuilding, petroleum, aviation and machine tool industries, Jiangmen Hydraulic equipment Price Hydraulic technology lists some application examples of hydraulic and pneumatic transmission.
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, Jiangmen Hydraulic equipment 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, Jiangmen Hydraulic equipment 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.
