The coal mill lubricating oil pump is generally a vertical pump, that is, the pump body is a kind of pump in a vertical type, the motor and the pump body are connected vertically, and the power transmission is realized between the motor and the pump body through the shaft coupling. It is vertical from the appearance, and this design makes it occupy small floor area when installing, so it is widely applied.

[0003] For example, the Chinese utility model patent with the application number 202121114228.5 (the authorized announcement number is CN21556669) discloses a high-stability vertical pump that can be sealed and installed, which discloses a similar vertical pump structure. However, there are still problems here. After the motor of this kind of vertical pump is replaced, the three-phase electric phase of the motor is rearranged due to the reconnection of the cable, and we cannot accurately determine the direction of the motor at this time. Therefore, before the motor and the pump body are reconnected, the motor needs to be tested and operated individually to timely confirm whether the direction and other operating parameters of the motor are good, so as to avoid that the motor with poor direction or operating parameters is directly connected to the pump body and the pump body is damaged.
