When maintaining vacuum oil injection equipment, several key points should be noted: disassembly, cleaning, inspection and assembly. It is very important that vacuum equipment, regardless of its size, belongs to precision mechanical equipment.
The vacuum oil injection equipment manufacturer explains that when disassembling, the principle of handling with care should be followed. Do not act rashly and never use a sledgehammer to strike. When cleaning parts, be thorough and clean to facilitate the identification of problems and potential hazards. Vacuum pump products are quite different from general mechanical products. While general mechanical products often have beveled edges and corners, vacuum pumps have distinct edges and corners, which can easily hurt hands. Extra care should be taken and this must be remembered. Inspection is a meticulous job. No detail should be overlooked, and there must be no mentality of taking chances.
There was a piece of equipment that the user had stored for four years. After completing the routine cleaning work and connecting the pipelines step by step to start vacuuming, it still failed to meet the factory standards. Everything was checked, but the vacuum rubber hose for gas supply was not inspected. At that time, it was thought that the vacuum rubber hose would not leak. The result was exactly the opposite. The problem lay with this vacuum rubber hose.
Furthermore, whether the vacuum pump components are cleaned with gasoline or other solvents, assembly must be carried out only after the gasoline or solvents have completely evaporated. If the vacuum pump oil is mixed with other oils, solvents, or water, it will damage its performance and affect the performance indicators of the vacuum pump. The rubber ring should be wiped clean and carefully inspected for any defects such as cracks. Also, check if the dimensions are correct. Pay special attention to those with similar diameters, such as 3.1mm and 3mm. The incorrect dimensions of 5.7mm and 6mm will affect the sealing.
All rubber rings with heating positions must be replaced each time they are disassembled and cleaned, such as the interfaces of the oil booster pump. When assembling, the pump components also need to be handled with care. When tightening the screws, apply force evenly and start tightening from the opposite corners. Dynamic seals mostly use shaft seals. When installing shaft seals, be careful. First, check if there are any defects in the shaft seal itself, whether the sealing surface is flat, and the elasticity of the shaft seal spring.
