Description
Technical field
The present invention relates to a kind of pumping equipment, particularly a kind of immersion pumping equipment.
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 immersion pumping equipment.
In order to achieve the above object, the immersion pumping equipment that the present invention proposes, including the housing with screw rod cavity, the one group of screw rod being arranged in screw rod cavity, 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: the water section that enters of described water outlet has cydariform chamber, it is provided with by the second motor-driven impeller in cydariform chamber, the water inlet of cydariform chamber is horizontal positioned, cydariform chamber outlet is in vertically placing, it is provided with pressure regulating cavity on the housing of described screw shaft rear end, described screw shaft rear end is inserted in this pressure regulating cavity, pressure regulating cavity is embedded with airtight and watertight padding with the gap location of screw shaft, cannelure is offered along perisporium in the top of described screw rod cavity, described cannelure and pressure regulating cavity pass through pipeline connection between leading to.
Immersion pumping equipment 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.
6, being provided with buffer chamber on described pipeline, the volume of described buffer chamber is not less than 10 times of pressure regulating cavity cumulative volume.
7, described buffer chamber is arranged near cannelure one end.
On the one hand, the present invention is provided with vane type water pump at the outlet of screw pump, by the work of vane type water pump, reduces the pressure of screw pump water outlet to a certain extent；On the other hand, the hydraulic pressure of screw pump front end is introduced to the rear end of screw shaft by the present invention, is pushed up by screw shaft, resists the powerful recoil suffered by screw rod.Two aspects combine, 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.Buffer chamber is set near cannelure one end and can reduce the high speed shake of cannelure output current, it is ensured that possess more stable pressure in pressure regulating cavity, stop the generation of bearing shake.
