The maintenance of vacuum oiling equipment should pay attention to several links, disassembly, cleaning, inspection and assembly. It is very important that vacuum equipment, large or small, belongs to precision mechanical equipment.
The manufacturer of vacuum oiling equipment explained that the disassembly should follow the principle of handling with care, not recklessly, and must not be knocked with a sledgehammer; Parts shall be cleaned thoroughly to find problems and hidden dangers; Vacuum pump products are quite different from general mechanical products. General mechanical products are mostly inverted and chamfered, while the edges and corners of vacuum pumps are clear, which is easy to hurt hands. You should be more careful and remember. Inspection is a meticulous work. Don't lose every detail, let alone have a fluke mentality.
The user has stored one equipment for 4 years, finished the routine cleaning work, connected the pipeline step by step and began to vacuumize, but it could not meet the factory standard. Everything was checked, that is, a vacuum hose for gas supply was not checked, so it was thought that the vacuum hose would not leak at that time. On the contrary, the problem lies in this vacuum hose.
In addition, the vacuum pump parts cleaned with gasoline or other solvents must not be assembled until the gasoline or solvent is completely volatilized. If the vacuum pump oil is mixed with other oils, solvents or water, its performance will be damaged and the performance index of the vacuum pump will be affected. The rubber ring shall be wiped clean and carefully checked for defects, such as cracks. And whether the size is correct. Pay special attention to the diameter of similar sizes, such as 3.1 mm and 3 mm; Incorrect dimensions of 5.7 mm and 6 mm will affect the seal.
The rubber ring with heating position must be replaced every time it is disassembled and cleaned, such as each interface of oil booster pump. Pump parts also need to be handled with care during assembly; Tighten the screws evenly and tighten them diagonally. The dynamic seal is multi-purpose shaft seal. Be careful when installing the shaft seal. First check whether the shaft seal itself has defects, whether the sealing surface is flat, and how elastic the shaft seal spring is.
