Problems solved by technology

[0002] At present, most of the submerged pumps on the market adopt a single-suction structure, and there is no shaft seal device on the back of the impeller, resulting in serious leakage in the high-pressure area on the back, large volume loss, low pump efficiency, and the axial force generated during operation. Damaged motor bearings
There are also a small number of submerged pumps that adopt a double-suction arrangement structure, but the pump body structure follows the traditional split structure, and the structure and manufacturing process are complicated.

Abstract

The invention discloses a double-suction submerged pump. The double-suction submerged pump comprises a motor, a coupling, a pump shaft, a bracket, a sliding bearing, a pump cover, an impeller, a shaftcap, a pump body and a filter screen. The impeller of the double-suction submerged pump is of a double-suction structure arranged symmetrically, and a labyrinth seal structure is arranged at impellerrings on both sides of the impeller. The axial force of the double-suction submerged pump is effectively balanced during operation, and a labyrinth seal is adopted at the impeller ring portions on both sides of the impeller, so that the machine efficiency is high, and reduction of energy consumption is facilitated.

Description

Technical field [0001] The invention relates to a pump, in particular to a double-suction submerged pump. Background technique [0002] At present, most of the submerged pumps on the market adopt a single-suction structure, and there is no shaft seal device on the back of the impeller, which causes serious leakage in the high-pressure area on the back, large volume loss, low pump efficiency, and the axial force generated during operation is easy to cause The motor bearing is damaged. There are also a small number of submersible pumps with a double-suction arrangement, but the pump body structure follows the traditional split structure with a complicated structure and manufacturing process. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a double-suction submerged pump with small internal volume loss and high overall machine efficiency, which is beneficial to reducing energy consumption and greatly improving the service l...
