Description

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：First, impeller pump, such as：Centrifugal pump, mixed-flow pump, axial-flow pump Deng, Turo pump；2nd, displacement pump, such as：Plunger displacement pump, gear pump, screw pump, vane pump etc.；3rd, other types, such as：Jet pump, water Hammer pump etc..
Screw pump belongs to displacement pump, and lift high single current amount is few, is particularly suitable for and loose thick liquid.When screw rod high-speed rotation When, rear end bearing is subject to larger 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 needing high rotating speed, preferable solution is the pressure reducing the port of export realizing.However, in the face of big lift Demand, reducing outlet pressures becomes a difficult problem.
Content 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, combination type immersible pump proposed by the present invention, 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 is connected with inlet channel, and upper end is connected with water outlet, Screw shaft rear and front end couples the first motor by bearings, screw shaft by drive mechanism, also has impeller and drives impeller Second motor of rotation, the water section that enters of described water outlet has cydariform chamber, and described impeller is installed on cydariform within the chamber, cydariform chamber The water inlet of room is in horizontal positioned, and cydariform chamber outlet is in vertical placement, and the water outlet being connected with cydariform chamber has been inserted into Gas blow pipe, the blowing direction of described gas blow pipe connects air pump towards the water inlet of cydariform chamber, gas blow pipe upper end.
Combination type immersible pump of the present invention, is further improved by：
1st, described water outlet enter water section flare, water inlet side port is little, and water outlet side port is big.
2nd, described impeller is to have 7 blades.
3rd, the water outlet being connected with described cydariform chamber outlet and the angle of horizontal plane are 70-90 °.
4th, the inwall of described inlet channel has helical structure.
5th, the gas outlet of described gas blow pipe is located at water outlet center.
The present invention is provided with the gas blow pipe of vane type water pump and air pump in the outlet of screw pump, by vane type water pump and The work of air pump, reduces the pressure of screw pump water outlet to a certain extent, reduce screw shaft suffered to counteracting force, from And reduce the load of bearing, reduce the abrasion of bearing, extend the service life of immersible pump, and turn for improving screw pump further Speed provides guarantee.
The air-flow being blown into from gas blow pipe, in the middle position of spiral current, is mingled with water to preshoot, thus being current Provide more powerful impulse force, further reduce the pressure of screw pump water side.
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 bell shape, can reduce the pressure of water side further.
