Abstract

The present invention relates to longer screw immersible pump in a kind of service life, including the housing with screw rod cavity, the one group of screw rod being arranged in screw rod cavity, 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 provided with pressure regulating cavity on the housing of screw shaft rear end, 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 screw rod cavity, cannelure and pressure regulating cavity pass through pipeline connection between leading to.The hydraulic pressure of screw pump front end is introduced to the rear end of screw shaft by the present invention, screw shaft is pushed up, resist the powerful recoil suffered by screw rod, the stress making screw shaft more balances, 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 screw 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 screw 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 the work side of a kind of screw immersible pump Method.
In order to achieve the above object, the screw immersible pump that the present invention proposes, including having the housing of screw rod cavity, arrange One group of screw rod in screw rod cavity, described screw rod lower end connects an inlet channel, and upper end connects water outlet, before and after screw shaft two End is by bearings, and screw shaft couples the first motor by drive mechanism, it is characterised in that: on the housing of described screw shaft rear end Being provided with pressure regulating cavity, described screw shaft rear end is inserted in this pressure regulating cavity, and the gap location of pressure regulating cavity and screw shaft is embedded with sealing and fills out Material, the top of described screw rod cavity is offered between cannelure, described cannelure and pressure regulating cavity lead to along perisporium and is passed through pipeline connection.Institute The method of work stated includes: the hydraulic pressure of screw pump front end is introduced to the rear end of screw shaft, is pushed up by screw shaft, resist spiral shell Powerful recoil suffered by bar, makes the stress balance of screw shaft.
Screw immersible pump of the present invention, is further improved by:
1, the inwall of described inlet channel has helical structure.
2, being provided with buffer chamber on described pipeline, the volume of described buffer chamber is not less than the 10 of pressure regulating cavity cumulative volume Times.
3, described buffer chamber is arranged near cannelure one end.
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 screw rod Suffered powerful recoil, makes the stress of screw shaft more balance, thus reduces the load of bearing, reduces the mill of bearing Damage, extend the service life of immersible pump, and provide guarantee for improving screw pump rotating speed further.
Buffer chamber is set near cannelure one end and can reduce the high speed shake of cannelure output current, it is ensured that pressure regulating cavity Inside possess more stable pressure, stop the generation of bearing shake.
Accompanying drawing explanation
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is screw submersible pump structure schematic diagram of the present invention.
In figure, label is schematically as follows:
1-screw rod cavity, 2-housing, 3-screw rod, 4-inlet channel, 5-water outlet, 6-screw shaft, 7-bearing, 8-drive mechanism, 9- First motor, 15-pressure regulating cavity, 16-pipeline, 17-buffer chamber, 18-cannelure.
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 screw immersible pump of the present invention, including having the housing 2 of screw rod cavity 1, it is arranged at screw rod chamber One group of screw rod 3 of internal 1, screw rod 3 lower end connects inlet channel 4, and upper end connects has water outlet 5, the inwall of inlet channel 4 to have spiral shell Rotation shape structure, screw shaft 6 rear and front end is supported by bearing 7, and screw shaft 6 couples the first motor 9, screw shaft 6 by drive mechanism 8 Being provided with pressure regulating cavity 15 on the housing of rear end, screw shaft 6 rear end inserts in this pressure regulating cavity 15, between pressure regulating cavity 15 and screw shaft 6 Being embedded with airtight and watertight padding at gap, cannelure 18 is offered along perisporium in the top of screw rod cavity 1, cannelure 18 and pressure regulating cavity 15 logical between Being connected by pipeline 16, pipeline 16 is provided with buffer chamber 17 near cannelure 18 one end, the volume of buffer chamber 17 is not 10 times of pressure regulating cavity 15 cumulative volume.
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.
