The oil cylinder shall be assembled in a special workshop or assembly area, and the temperature shall be kept at 20~250C, ynz Oil cylinder Price 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 ynz Oil 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.
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, ynz Oil 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 ynz Oil cylinder Price The erosion of acid gas requires us to apply proper amount of grease to protect it.
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, ynz Oil cylinder 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, ynz Oil cylinder 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.
The two lips of the seal have two contact circumferential surfaces. Whether the force on the inner and outer circumferences is evenly distributed means that the force on the two circumferences cannot be zero. If the force on a certain point is zero, the shaft seal has inner and outer lips, ynz Oil cylinder The outer lip is installed in the groove to contact the outer wall, and the inner lip is in contact with the piston rod surface. Both lips have an interference amount, which is equal to the generation of two contact circumferential surfaces, that is, the generation of two circumferential rebound forces. How to determine the magnitude of the circumferential force? Both the inner and outer lips of the seal have two chamfers. Since the interference of the same inner and outer lips is certain, ynz Oil cylinder Price The angle of the chamfer determines the size of the circumferential area of the inner and outer contact of the two lips.
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, ynz Oil cylinder Price 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, ynz Oil cylinder As a result, the viscosity of the working medium decreases or the possibility of leakage increases.
