Abstract

The invention provides a submerged pump capable of achieving automatic adjusting according to water level and belongs to the field of automatic-adjusting submerged pumps. The submerged pump comprises a submerged pump body. The submerged pump is provided with a rail which is fixed on the lateral wall of a pond through a support. The submerged pump body is mounted on the rail through a slider. A drive gear and a driven gear are respectively disposed at the top end and the lower end of the rail. The rotary shaft of the drive gear is connected to the rotor of a reduction motor through a coupler. A chain winds around the drive gear and the driven gear to be fixed at two ends of the slider. The reduction motor is connected to a power supply through a control device. The submerged pump has the advantages that that the positions of the submerged pump can be automatically adjusted according to the water level, demounting is not needed, and the submerged pump is long in service life and labor saving.

Description

technical field [0001] The invention provides a submersible pump with automatic adjustment of liquid level, which belongs to the field of automatic adjustment submersible pumps. Background technique [0002] Submersible pumps will be installed in the pool of the pumping station of the open-pit mining plant, but the water level in the pool of the pumping station is constantly being consumed, replenished, and the water level is frequently changed during the process of natural rainfall and drought. If the water pressure is constant, it is necessary to continuously disassemble the submersible pump according to the water level and reinstall the submersible pump according to the water level to ensure that the water pressure of the water pumped by the submersible pump is constant. [0003] The disadvantages of the existing technology are: firstly, the submersible pump cannot adjust its position independently according to the water level; secondly, frequent disassembly and assembly ...
