Abstract

The invention relates to a combined submersible pump. The combined submersible pump comprises a submersible screw pump, wherein the submersible screw pump comprises a casing and a group of screws arranged in the casing; lower ends of the screws are connected with a water inlet channel, and upper ends of the screws are connected with a water outlet channel; front and back ends of screw shafts are supported by bearings; a water inlet section of the water outlet channel is provided with a drum-shaped chamber, an impeller is mounted in the drum-shaped chamber, a water inlet of the drum-shaped chamber is placed horizontally, and a water outlet of the drum-shaped chamber is placed vertically. According to the combined submersible pump, an impeller type water pump is arranged at the water outlet of the screw pump, through working of the impeller type water pump, the pressure at the water outlet of the screw pump is reduced to a certain extent, and reactive forces applied to the screw shafts are reduced, so that loads of the bearings are reduced, abrasions to the bearings are reduced, the service life of the submersible pump is prolonged, and further increase of the revolving speed of the screw pump is guaranteed.

Description

A kind of combined type submersible pump
Technical field
The present invention relates to a kind of submersible pump, particularly a kind of combined type submersible pump.
Background technique
Submersible pump is the visual plant of deep-well water lift, is widely used in industrial or agricultural.
In general, according to drainage principle, water pump can be divided into: one, impeller pump, as: centrifugal pump, mixed flow pump, axial-flow pump etc., torque flow pump; Two, displacement pump, as: plunger pump, gear pump, screw pump, vane pump etc.; Three, other types, as: Jet injector, hydraulic ram etc.
Screw pump belongs to displacement pump, and the high single current amount of lift is few, is particularly suitable for and loose thick liquid.When screw rod High Rotation Speed, rear end bearing is subject to larger pressure, accelerated wear test, and the while has also been limited the rotating speed of screw pump.Bearing pressure mainly comes from the reaction force of screw rod, and for a screw submersible pump, this reaction force is mainly determined by rotating speed and outlet end pressure.When the high rotating speed of needs, desirable solution is that the pressure that reduces outlet end is realized.Yet, in the face of the demand of large lift, reduce outlet end pressure and become a difficult problem.
Summary of the invention
The object of the invention is to: overcome the defect of above-mentioned prior art, propose a kind of combined type submersible pump.
In order to achieve the above object, the combined type submersible pump that the present invention proposes, it has screw submersible pump, described screw submersible pump comprises housing, be arranged at one group of screw rod in housing, described screw rod lower end is connected with inlet channel, upper end is connected with water outlet, screw axis rear and front end is by bearings, screw axis connects the first motor by driving mechanism, it is characterized in that: second motor also with impeller and drives impeller rotation, the water section that enters of described water outlet has cydariform chamber, described impeller is installed in cydariform chamber, the water inlet of cydariform chamber is horizontal positioned, cydariform chamber water outlet is vertical placement.
Combined type submersible pump of the present invention, further improves and is:
1, described water outlet enter water section flare, influent side is young, water outlet side mouth is large.
2, described impeller is for having 7 blades.
3, the water outlet being connected with described cydariform chamber water outlet and the angle of horizontal plane are 70-90 °.
4, the inwall of described inlet channel has helical structure.
5, the water outlet being connected with cydariform chamber has helical structure.
The present invention is provided with impeller type water pump at the water outlet of screw pump, by the work of impeller type water pump, reduced to a certain extent the pressure of screw pump water outlet, reduce the suffered right reaction force of screw axis, thereby reduce the load of bearing, reduce the wearing and tearing of bearing, extend the working life of submersible pump, and provide guarantee for further improving screw pump rotating speed.
The present invention the water inlet of screw pump to and water outlet all carry out spirality processing, make ingoing stream more regular, reduce resistance, improve the efficiency of drawing water.Water outlet is designed to horn mouth shape, can further reduce the pressure of waterexit end.
