[0002] A submersible pump is a pump whose main flow-through component, the impeller, is immersed in the liquid being transported. It is widely used in fields such as petroleum, chemical industry, and environmental protection, especially in occasions where it is necessary to pump liquid from the bottom of a container. The liquid depths involved in different occasions are not the same, so there are also different requirements for the height of the submersible pump. Most of the part of the traditional submersible pump immersed in the liquid is an integral structure. Although this can keep the pump stable, the height is thus fixed. When the liquid depth in the same occasion changes, especially increases, the original submersible pump can no longer meet the usage requirements. Based on this situation, how to enable users to conveniently adjust the height of the submersible pump according to the actual liquid depth of the application occasion has increasingly become an urgent problem for relevant technical personnel to solve.
