Abstract

The present invention relates to a kind of combination type immersible pump, there is screw submersible pump, screw submersible pump includes housing, it is arranged at one group of screw rod in housing, screw rod lower end connects inlet channel, upper end connects water outlet, screw shaft rear and front end is by bearings, the water section that enters of water outlet has cydariform chamber, in cydariform chamber, impeller is installed, the water inlet of cydariform chamber is horizontal positioned, cydariform chamber outlet is provided with vane type water pump in the vertically placement present invention at the outlet of screw pump, work by vane type water pump, reduce the pressure of screw pump water outlet to a certain extent, reduce screw shaft suffered to counteracting force, thus reduce the load of bearing, reduce the abrasion of bearing, extend the service life of immersible pump, and provide guarantee for improving screw pump rotating speed further.

Description

A kind of combination type immersible pump
Technical field
The present invention relates to a kind of immersible pump, particularly a kind of combination type immersible pump.
Background technology
Immersible pump is the visual plant of deep-well water lift, is widely used in industrial or agricultural.
In general, water pump can be divided into according to drainage principle: one, impeller pump, such as: centrifugal pump, mixed-flow pump, axial-flow pump etc., Turo pump；Two, displacement pump, such as: plunger displacement pump, gear pump, screw pump, vane pump etc.；Three, other types, such as: jet pump, hydraulic ram etc..
Screw pump belongs to displacement pump, and lift height single current amount is few, is particularly suitable for and loosens thick liquid.When screw rod high speed rotating, rear end bearing is subject to bigger pressure, accelerated wear test, also limit the rotating speed of screw pump simultaneously.Bearing pressure mostlys come from the counteracting force of screw rod, and for a screw submersible pump, this counteracting force is mainly determined by rotating speed and outlet pressures.When the high rotating speed of needs, preferable solution is that the pressure reducing the port of export realizes.But, in the face of the demand of big lift, reduce outlet pressures and become a difficult problem.
Summary of the invention
It is an object of the invention to: overcome the defect of above-mentioned prior art, propose a kind of combination type immersible pump.
In order to achieve the above object, the combination type immersible pump that the present invention proposes, it has screw submersible pump, described screw submersible pump includes housing, it is arranged at one group of screw rod in housing, described screw rod lower end connects inlet channel, upper end connects water outlet, screw shaft rear and front end is by bearings, screw shaft couples the first motor by drive mechanism, it is characterized in that: also there is impeller and the second motor driving impeller to rotate, 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 outlet is in vertically placing.
Combination type immersible pump of the present invention, is further improved by:
1, described water outlet enter water section flare, water inlet side port is little, and water outlet side port is big.
2, described impeller is for having 7 blades.
3, the water outlet being connected with described cydariform chamber outlet is 70-90 ° with the angle of horizontal plane.
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 vane type water pump at the outlet of screw pump, work by vane type water pump, reduce the pressure of screw pump water outlet to a certain extent, reduce screw shaft suffered to counteracting force, thus reduce the load of bearing, reduce the abrasion of bearing, extend the service life of immersible pump, and provide guarantee for improving screw pump rotating speed further.
The present invention carries out spiral type process in the water inlet of screw pump to water outlet, makes entrance current more regular, reduces resistance, improves efficiency of drawing water.Outlet is designed to horn mouth shape, it is possible to reduce the pressure of water side further.
Accompanying drawing explanation
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is combination type submersible pump structure schematic diagram of the present invention.
In figure, label is schematically as follows:
1-screw submersible pump, 2-housing, 3-screw rod, 4-inlet channel, 5-water outlet, 6-screw shaft, 7-bearing, 8-drive mechanism, 9-the first motor, 11-cydariform chamber, 12-impeller.
Detailed description of the invention
The present invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, for combination type immersible pump of the present invention, there is screw submersible pump 1, described screw submersible pump 1 includes housing 2, it is arranged at one group of screw rod 3 in housing 2, screw rod 3 lower end connects inlet channel 4, upper end connects water outlet 5, the inwall of inlet channel 4 has helical structure, screw shaft 6 rear and front end is supported by bearing 7, screw shaft 6 couples the first motor 9 by drive mechanism 8, the water section that enters of water outlet 5 has cydariform chamber 11, the water outlet 5 being connected with cydariform chamber 11 also has helical structure, impeller 12 is installed in cydariform chamber 11, impeller 12 is for having 7 blades.The water inlet of cydariform chamber 11 is horizontal positioned, and cydariform chamber 11 outlet is in vertically placing.As it can be seen, water outlet 5 enter water section flare, water inlet side port is little, and water outlet side port is big.
In addition to the implementation, the present invention can also have other embodiments.The technical scheme that all employing equivalents or equivalent transformation are formed, all falls within the protection domain of application claims.
