Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of drainage pump equipment, and particularly relates to an assembly method of a drainage pump. BACKGROUND

[0002] The drainage pump is used for draining liquid in a water pool or a large liquid storage tank.

[0003] The drainage pump used in a building includes a submersible sewage pump, a submerged drainage pump, a vertical sewage pump and a horizontal sewage pump. Since the space in the building is small and the drainage capacity is small, the submersible sewage pump and the submerged drainage pump are preferred, and the submerged drainage pump is generally used in important places. The vertical sewage pump and the horizontal sewage pump require a shock isolation foundation, a self-filling water suction and a certain space, and thus are less used in the building.

[0004] During the assembly of the drainage pump, the motor and the pump body are installed on the base, and then are connected through the shaft coupling. However, during the assembly, once the position needs to be adjusted, the position of the motor or the pump body needs to be manually moved. Since the motor and the pump body are heavy, the base, the motor or the outer wall of the pump body is easily abraded during the movement, which causes rust of the drainage pump after long-term use and reduces the service life of the drainage pump. SUMMARY

[0005] The application aims to solve the above technical problems in the prior art, and provides an assembly method of a drainage pump. The base is placed on the assembly table, and the base is fixed on the middle of the top surface of the assembly table through the limiting and fixing assembly. The fixing of the base increases the stability of the installation of the motor and the pump body, and ensures the accuracy of the fixing of the motor and the pump body. The motor is fixed through the clamping assembly one, the motor is moved to the base through the slide rail of the clamping assembly one, and then the motor is lowered to the installation position of the base through the clamping assembly one. The pump body is fixed through the clamping assembly two, the motor is moved to the base through the slide rail of the clamping assembly two, and then the motor is lowered to the installation position of the base through the clamping assembly two. Then, the output end of the motor is connected with the pump body through the shaft coupling. During the connection, the clamping assembly one and the clamping assembly two cooperate to finely adjust the position of the motor and the body. Finally, the protective cover is arranged outside the shaft coupling, and the protective cover protects the shaft coupling. Finally, the protective cover, the motor and the pump body are fixedly connected to the base. During the installation of the motor and the pump body, the motor and the pump body are prevented from colliding with and rubbing against the base, the integrity of the outer wall of the motor, the pump body and the base is ensured, and the normal service life of the drainage pump is ensured.

Then, the fastening nut one 20 is tightened. Thus, the position of the adjusting rod 16 is fixed. The uniformly distributed threaded connecting holes 17 facilitate the fixation of the fixed block 15, the adjusting rod 16 and the limiting seat 14.
