In the previous section, we talked about two reasons to prevent oil leakage of explosion-proof motors. Today, Yuneng explosion-proof motor manufacturers will talk about the other two preventive measures in order to serve customers more conveniently.

1. There are quality problems of sliding bearings in the installation and debugging process
The problem of installation and commissioning is mainly the adjustment of the oil supply pressure. When the explosion-proof motor is installed and debugged, the oil inlet pressure is adjusted to be relatively high, the oil in the bearing oil tank is too high, and oil leaks to the inside and outside of the explosion-proof motor. Therefore, it is necessary to strictly follow the instruction manual of the explosion-proof motor manufacturer to adjust the pressure of the oil inlet of the bearing to maintain a certain flow rate so that the oil level inside the bearing is stable at 1/2-2/3 of the height of the bearing oil mark.

2. Explosion-proof motor design results in stable sliding bearing oil leakage
In the structural design of the explosion-proof motor, the interior of the explosion-proof motor is close to the inner side of the sliding shaft. When the explosion-proof motor is running, a negative pressure is formed inside the sliding bearing. to the outside of the explosion-proof motor. The negative pressure at the inner surface of the bearing can be reduced, the sealing of the sliding bearing can be increased, and the oil mist inside the sliding bearing can be reduced. The structure of the sliding bearing is improved, and a floating seal is added on the matching sealing surface between the inner cover of the sliding bearing and the shaft.

Summarize:
In the context of the increasing application range of high-voltage explosion-proof motors, we should start from the design, production and assembly of high-voltage explosion-proof motors to fully guarantee the manufacturing quality of high-voltage explosion-proof motors. Sliding bearings have an important impact on the operation and safety of high-voltage explosion-proof motors, and are also key parts that are prone to negligence in the actual process. We should continue to attach great importance to key links such as the design, production, and installation of sliding bearings. Starting from actual specific operations, Improve the safety and stability of sliding bearings, and create a new technology guarantee system for the processing and operation of high-voltage explosion-proof motors
