Abstract
The invention relates to an immersed pumping device which comprises a casing and screw rods, wherein screw shafts are connected with a first motor through a drive mechanism; a drum type chamber is formed in a water inlet section of a water outlet channel, an impeller driven by a second motor is mounted in the drum type chamber, pressure adjusting cavities are formed in the casing at the rear ends of the screw shafts, the rear ends of the screw shafts are inserted into the pressure adjusting cavities, sealing filler is embedded into gaps between the pressure adjusting cavities and the screw shafts, a hydraulic oil pump is connected with the pressure adjusting cavities through pipelines, and pressure sensors used for monitoring water pressure are arranged at the upper end and the lower end of a screw rod cavity respectively. On one hand, an impeller type water pump is arranged at a water outlet of a screw pump, and the pressure of the water outlet of the screw pump is reduced through working of the water pump; on the other hand, positive pressure is input into the pressure adjusting cavities through the hydraulic oil pump, and bearings are upwards pushed; and accordingly, in combination of the two aspects, the counter acting force borne by the screw shafts is reduced, the load and the abrasion of the bearings are reduced, and the service life of a submersible pump is prolonged.
Description
Technical field
The present invention relates to a kind of water plug, particularly a kind of immersion type water plug.
Background technique
Submersible pump is the important device of deep-well water lift, is widely used in industrial or agricultural.
In general, according to drainage principle, water pump can be divided into: one, impeller pump, as: centrifugal pump, mixed flow pump, axial-flow pump etc., torque flow pump; Two, displacement pump, as: plunger pump, gear pump, screw pump, vane pump etc.; Three, other types, as: Jet injector, hydraulic ram etc.
Screw pump belongs to displacement pump, and the high single current amount of lift is few, is particularly suitable for and loose thick liquid.When screw rod High Rotation Speed, rear end bearing is subject to larger pressure, accelerated wear test, and the while has also been limited the rotating speed of screw pump.Bearing pressure mainly comes from the reaction force of screw rod, and for a screw submersible pump, this reaction force is mainly determined by rotating speed and outlet end pressure.When the high rotating speed of needs, desirable solution is that the pressure that reduces outlet end is realized.Yet, in the face of the demand of large lift, reduce outlet end pressure and become a difficult problem.
Summary of the invention
The object of the invention is to: overcome the defect of above-mentioned prior art, propose a kind of immersion type water plug.
In order to achieve the above object, the immersion type water plug that the present invention proposes, comprise the housing with screw rod cavity, be arranged at one group of screw rod in screw rod cavity, described screw rod lower end is connected with inlet channel, upper end is connected with water outlet, screw axis rear and front end is by bearings, screw axis connects the first motor by driving mechanism, it is characterized in that: the water section that enters of described water outlet has cydariform chamber, in cydariform chamber, be provided with and be subject to the second motor-driven impeller, the water inlet of cydariform chamber is horizontal positioned, cydariform chamber water outlet is vertical placement, on the housing of described screw axis rear end, be provided with pressure regulating cavity, insert in this pressure regulating cavity described screw axis rear end, the gap location of pressure regulating cavity and screw axis embeds stuffing box packing, pressure regulating cavity is connected with hydraulic-pressure pump by pipeline, the lower end of described screw rod cavity and upper end are respectively equipped with for monitoring the pressure transducer of hydraulic pressure.
Immersion type water plug of the present invention, further improves and is:
1, described water outlet enter water section flare, influent side is young, water outlet side mouth is large.
2, described impeller is for having 7 blades.
3, the water outlet being connected with described cydariform chamber water outlet and the angle of horizontal plane are 70-90 °.
4, the inwall of described inlet channel has helical structure.
5, the water outlet being connected with cydariform chamber has helical structure.
6, on described pipeline, be provided with buffer chamber, the volume of described buffer chamber is not less than 10 times of pressure regulating cavity total volume.
7, described buffer chamber arranges near circular groove one end.
8, the signal output part of described pressure transducer connects central processor equipment.
On the one hand, the present invention is provided with impeller type water pump at the water outlet of screw pump, by the work of impeller type water pump, has reduced to a certain extent the pressure of screw pump water outlet; On the other hand, the present invention can obtain and should by adjusting this incoming pressure, will on screw axial, push away to the pressure of pressure regulating cavity input by gathering the lower end of screw rod cavity and the hydraulic pressure of upper end, resists the suffered powerful recoil of screw rod.Two aspect combinations, reduce the suffered right reaction force of screw axis, thereby reduce the load of bearing, reduce the wearing and tearing of bearing, extend the working life of submersible pump, and provide guarantee for further improving screw pump rotating speed.
The present invention the water inlet of screw pump to and water outlet all carry out spirality processing, make ingoing stream more regular, reduce resistance, improve the efficiency of drawing water.Water outlet is designed to horn mouth shape, can further reduce the pressure of waterexit end.Near circular groove one end, the high speed shake that buffer chamber can reduce circular groove output current is set, guarantees to possess more stable pressure in pressure regulating cavity, stop the generation of bearing shake.
