The reason for oil leakage in the BMW X1 vacuum pump may be due to excessively high oil level, causing oil leakage through the inner holes of the bearing covers at both ends of the bearing housing. Oil leakage at the sealing kit points. Oil leakage at the vacuum pump end cover. Oil leakage at the vacuum pump bearing position, which YAZHILEIDE Electromechanical Technology believes is mainly caused by hardened oil seals. Introduction to vacuum pumps: A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical, or physicochemical methods to evacuate a container to obtain a vacuum. A vacuum pump is a device that improves, generates, and maintains a vacuum in a closed space through various methods. Overall structural types of vacuum pumps: The arrangement structure of the vacuum pump body determines the overall structure of the pump. In the vertical structure, the inlet and outlet ports are horizontally arranged, making assembly and pipeline connection more convenient. However, the pump's center of gravity is higher, resulting in poor stability during high-speed operation, so this type is mostly used for small pumps.
