Therefore, it has a special role and an important position. It has been closely related to human production and life for a long time. With the acceleration of national infrastructure construction and urbanization, traditional concrete pumping stations are increasingly exposing their own insurmountable shortcomings, mainly including the following points:

1) It occupies a large area. It is not only necessary to set up the inlet and outlet pools and pipelines necessary for the operation of the pump, but also to set up the operation control room, personnel living room and equipment maintenance room, etc.

2) The construction period is long. From foundation pit excavation, concrete pouring and maintenance to equipment installation and commissioning, the entire construction period takes 3-6 months or even several years.

3) The cost is high. Due to the large area, deep excavation depth, large amount of concrete pouring and long construction period, plus the cost of equipment and personnel operation and maintenance, the cost investment of traditional pumping stations is about several million to tens of millions.

4) poor coordination. The equipment in the traditional pumping station is supplied and constructed by different manufacturers. If the coordination is not effective, it is easy to have poor matching and coordination between equipment, equipment and civil engineering, and may even cause permanent quality defects.

5) Cannot be reused. Once the traditional concrete pumping station is built, it will be fixed in one place and cannot be moved or transported. It cannot meet the collection and transportation needs of some temporary, staged and location-changing sewage and wastewater.

6) The degree of automation is low. The traditional pumping station is supplied and constructed by multiple parties, and the degree of integration is not high, resulting in a low degree of automatic control of the pumping station.
