Problems solved by technology

The vertical submersible sewage pumps currently used have the following disadvantages: many sewage pumps are installed in the coupling installation mode, and the pump is fixed in one position. The sewage discharge area of ​​such pumps is limited. If the position of the sewage pump is to be adjusted, the coupling device It also needs to be adjusted, which will require re-foundation, and some need to reserve anchor screws, etc., which will cause great inconvenience; most submersible sewage pumps use the method of directly connecting the pump body with the outlet pipe seat. When the sewage pump is overhauled, it is necessary to remove the outlet pipe seat to overhaul the pump body. This installation method is not only difficult to install, but also inconvenient to detect and maintain
[0003] Such as the submersible sewage pump installation structure of the invention patent CN203362634U, it is mainly to develop a submersible sewage pump installation structure that is quick to install, and easy to detect and maintain. The pump is installed on the foundation, but if the pump needs to be adjusted to other positions, the foundation needs to be rebuilt, which is very complicated
For the large submersible sewage pump described in the invention patent 201110086723.4, the concrete base layer is used, and the installation structure is complicated, and related issues such as mobile installation and maintenance are not considered.
