Abstract

The invention relates to an immersed water pumping device adopting a central processing device. The immersed water pumping device comprises a shell and screws, and screw shafts are connected with a first motor through a transmission mechanism; a water inlet section of a water outlet channel has a drum-shaped cavity; impellers driven by a second motor are mounted inside the drum-shaped cavity; an air blowing pipe is inserted in the water outlet channel connected with the drum-shaped cavity; the air blowing direction of the air blowing pipe faces a water inlet of the drum-shaped cavity; pressure regulating cavities are arranged on the shells at the back ends of the screw shafts; the pressure regulating cavities are connected with a hydraulic oil pump through pipelines; and pressure sensors used for monitoring the water pressure are arranged at the upper ends and the lower ends of screw cavities. According to the immersed water pumping device, on one hand, an impeller type water pump and the air blowing pipe are arranged at a water outlet of a screw pump, and the pressure at the water outlet of the screw pump is reduced through the operation of the water pump and an air pump; on the other hand, the hydraulic oil pump inputs positive pressure to the pressure regulating cavities to push bearings upwards; and the two aspects are combined, so that the reacting force received by the screw shafts is reduced, the load of the bearings is reduced, the abrasion of the bearings is reduced, and the service life of a 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...
