Abstract

The invention relates to an immersed type pumping device which comprises a casing and screws, wherein screw shafts are connected with a first motor through a transmission mechanism, a drum-shaped cavity is formed in a water entry section of a water outlet channel, and an impeller driven by a second motor is mounted in the drum-shaped cavity; an air blowpipe is inserted into the water outlet channel connected with the drum-shaped cavity, and the air blowing direction of the air blowpipe faces a water inlet of the drum-shaped cavity; pressure regulating cavities are formed in the casing at rear ends of the screw shafts and are connected with a hydraulic oil pump through a pipeline, and pressure sensors for monitoring water pressure are arranged at the lower end and the upper end of a screw cavity respectively. On one hand, an impeller water pump and the air blowpipe are arranged at a water outlet of a screw pump, and pressure at the water outlet of the screw pump is reduce through working of the water pump and the air pump; on the other hand, forward pressure is input into the pressure regulating cavities by the hydraulic oil pump, so that bearings are pushed upwards; and in combination of the two aspects, the counter-acting force borne by the screw shafts is reduced, then the bearing loads are reduced, the bearing abrasion is reduced, and the service life of the submersible pump is prolonged.

Description

technical field [0001] The invention relates to a water pumping device, in particular to a submerged water pumping device. Background technique [0002] Submersible pump is an important device for pumping water from deep wells, and is widely used in industry and agriculture. [0003] Generally speaking, according to the principle of drainage, water pumps can be divided into: 1. Impeller pumps, such as: centrifugal pumps, mixed flow pumps, axial flow pumps, etc., swirl pumps; 2. Positive displacement pumps, such as: plunger pumps, gear pumps, Screw pump, vane pump, etc.; 3. Other types, such as: jet pump, water hammer pump, etc. [0004] The screw pump belongs to positive displacement pump, with high head and low flow rate, especially suitable for loose viscous liquid. When the screw rotates at a high speed, the back-end bearing is subjected to greater pressure, which accelerates wear and also limits the speed of the screw pump. The pressure on the bearing mainly comes fro...
