Abstract

The present invention relates to longer combination type immersible pump in a kind of service life, 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

The combination type immersible pump that a kind of service life is longer
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 Deng, Turo pump；Two, displacement pump, such as: plunger displacement pump, gear pump, screw pump, vane pump etc.；Three, other types, such as: jet pump, water Hammer pump 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 Time, rear end bearing is subject to bigger pressure, accelerated wear test, also limit the rotating speed of screw pump simultaneously.Bearing pressure mainly comes From in the counteracting force of screw rod, and for a screw submersible pump, this counteracting force is mainly by rotating speed and outlet pressures Determine.When the high rotating speed of needs, preferable solution is that the pressure reducing the port of export realizes.But, in the face of big lift Demand, reduces outlet pressures and becomes 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, and described screw rod is dived Water pump includes housing, is arranged at one group of screw rod in housing, and described screw rod lower end connects inlet channel, and upper end connects water outlet, Screw shaft rear and front end is coupled the first motor by bearings, screw shaft by drive mechanism, it is characterised in that: also there is impeller With the second motor driving impeller to rotate, the water section that enters of described water outlet has cydariform chamber, and described impeller is installed on cydariform chamber Indoor, the water inlet of cydariform chamber is horizontal positioned, and 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, by the work of vane type water pump, to a certain degree On reduce the pressure of screw pump water outlet, reduce screw shaft suffered to counteracting force, thus reduce the load of bearing, fall The abrasion of low bearing, extends the service life of immersible pump, and provides 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 it is shown in figure 1, be combination type immersible pump of the present invention, having screw submersible pump 1, described screw submersible pump 1 includes shell Body 2, is arranged at one group of screw rod 3 in housing 2, and screw rod 3 lower end connects inlet channel 4, and upper end connects water outlet 5, inlet channel 4 Inwall has helical structure, and screw shaft 6 rear and front end is supported by bearing 7, and screw shaft 6 couples the first electricity by drive mechanism 8 Machine 9, the water section that enters of water outlet 5 has cydariform chamber 11, and the water outlet 5 being connected with cydariform chamber 11 also has helical structure, Being provided with impeller 12 in cydariform chamber 11, impeller 12 is for having 7 blades.The water inlet of cydariform chamber 11 is horizontal positioned, drum Shape 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, water outlet side port Greatly.
In addition to the implementation, the present invention can also have other embodiments.All employing equivalents or equivalent transformation shape The technical scheme become, all falls within the protection domain of application claims.
