Hydraulic suspension type anti-leakage submersible pump

Abstract

The invention particularly relates to a hydraulic suspension type anti-leakage submersible pump. The problems that as for an existing submersible pump, the structural design is unreasonable, thereforeenergy consumption is large, the water outlet amount is small, and the service life of a motor is affected are solved. The hydraulic suspension type anti-leakage submersible pump comprises a cylindrical pump shell; a pump shaft is arranged at the axis of the cylindrical pump shell; the pump shaft is sleeved with a plurality of suspension type impellers distributed vertically; the suspension typeimpellers are made by connecting upper cover plates with lower cover plates through blades, and the outer diameter of each upper cover plate is smaller than that of the corresponding lower cover plate; suspension blocks are arranged on the lower end faces of the lower cover plates, wherein the suspension blocks and the lower cover plates are integrated, and the center line of each suspension blockis in an involute shape; suspension grooves are formed in the lower end faces of the suspension blocks; and stainless steel seal plates for supporting the suspension blocks correspondingly are arranged on the inner wall of the cylindrical pump shell. The structural design is reasonable and reliable, the axial force of a motor is reduced, and the service life of the motor is prolonged; and the water flow leakage phenomenon is eradicated, the water outlet amount of the submersible pump is increased, and the energy consumption is reduced by a large margin.

Description

technical field [0001] The invention relates to a submersible pump for wells, in particular to a hydraulic suspension type anti-leakage submersible pump. Background technique [0002] The impeller and the pump casing of the existing submersible pump adopt a radial seal ring structure, which is sealed by the centrifugal force generated by the rotation of the impeller driven by the motor. The water leakage of each stage of the impeller itself has a rotation gap of 0.15mm. More leakage will seriously affect the water output of the submersible pump and cause a lot of power consumption; moreover, the axial pressure of the existing submersible pump for wells acts on the thrust bearing of the motor. The greater the pressure, it will seriously affect the service life of the motor.
