Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy equipment, in particular to a low-lift flameproof submersible electric pump. Background Art

[0002] A submersible electric pump is a water pump in which both the pump body impeller and the motor driving the impeller are submerged in water to work. There are two types: deep well submersible electric pump and working surface submersible electric pump. The deep well submersible electric pump supplies power to the motor through a cable inserted into the well, eliminating the long transmission shaft. Therefore, it has a compact structure, light weight, and is easy to install, use and transfer. It has a trend of replacing long-shaft deep well pumps in areas with power supply, but it is not suitable for wells with high sand content and areas without power supply. The installation process of traditional submersible electric pumps is relatively cumbersome and complicated, and it is inconvenient to quickly locate and install the submersible electric pump. It is difficult to disassemble and remove the submersible electric pump from the fixed mounting seat, which brings inconvenience to the later maintenance of the submersible electric pump. In addition, the submersible pump will vibrate during operation, which will cause the submersible pump to be unstable during operation. Utility Model Content
