Pre-installation ① An important part of the pre-installation of the ferrule type pipe joint directly affects the reliability of the seal. Dedicated preprocessors for common needs. Fittings with small diameters can be pre-assembled on a vise. The detailed method is to use a joint as the mother body, and press the nut and the ferrule onto the pipe.
The safety valve is worn or the hydraulic oil is too dirty; the ball valve is corroded, the springs are insufficient or broken; the hydraulic oil is not converged; , Will make the safety valve closure strictly.
The sealing ring on the hydraulic cylinder piston, the sealing ring of the piston rod and the piston joint, and the sealing ring of the positioning valve are damaged. The processing method is: replace the sealing ring and the seal gear. However, it should be noted that the surface of the selected sealing ring should be smooth; no wrinkles, no cracks, no holes, no abrasions, etc.
The leakage of the hydraulic system will cause a reduction in hydraulic volume and cannot establish normal pressure, which will cause the system to not work properly. There are two main cases of leakage of the hydraulic system: external leakage and internal leakage. This article mainly introduces the two main leaks of the leakage failure of the hydraulic system and the main measures for leak -proof and leakage.
1. The SAE flange must have sufficient strength and must not be deformed when tightening. 2. The flange sealing surface should be cleaned up, and oil stains and rust must be carefully cleaned up when installing the SAE flange. 3. The gasket needs good oil resistance, heat resistance and aging resistance, as well as good elasticity and mechanical strength.
The main cause of hydraulic impact is the rapid change of the fluid flow, the inertia of the high -speed motion work component, and the reaction action of certain hydraulic components are not sensitive.
