Background
The submersible sewage pump is a pump product which is connected with a motor and simultaneously submerged to work under liquid, and compared with a common horizontal pump or a vertical sewage pump, the submersible sewage pump has the advantages of the following aspects:
(1) compact structure and small occupied area. The submersible sewage pump can be directly installed in a sewage pool because of submerged operation, a special pump room is not required to be built for installing the pump and the machine, and a large amount of land and capital construction cost can be saved.
(2) The installation and the maintenance are convenient. The small submersible sewage pump can be freely installed, the large submersible sewage pump is generally provided with an automatic coupling device to be automatically installed, and the installation and the maintenance are quite convenient.
(3) The continuous operation time is long. The submersible sewage pump has the advantages that the pump and the motor are coaxial, the shaft is short, the weight of rotating parts is light, so that the load (radial direction) borne by the bearing is relatively small, and the service life is much longer than that of a common pump.
(4) The problems of cavitation damage, irrigation and water diversion and the like do not exist. Particularly, the latter point brings great convenience to operators.
