Abstract

An energy saving deep well booster pump comprises a pump casing with a water outlet nozzle, the upside part of the pump casing is fixed at the mouth of a well, an axis penetrating into the water surface of a pump casing is arranged in the midst of the pump casing, a water stirring wheel is fixed on the axis positioned under water surface, a pipe barrel is sleeved on the axis with the upside end connected with the foundation of the pump casing by sealing connection and the lower end enclosed by a cover under the water stirring wheel, a driving wheel is fixed on the upside side of the axis, a water raising impeller is fixed on the axis inside the pump casing through keys and impeller keypads. The water raising impeller arranged on the axis in the mid part of the pump casing makes the water in the deep well get a pulling force from the upside and a pushing force from the underside, thus the forces exerted on the water stirring wheel positioned in lower side of the axis are reduced greatly, the power of the driving source is reduced too, and the operation efficiency is improved, thereby the deep well booster bump has the advantage of energy waving. The service life of the pump is prolonged because a position limiter arranged on the tubular axle makes the axis stable in the pipe barrel.

Description

The energy-saving power-boost deep-well pump

(1) technical field:

The utility model relates to a kind of engineering goods, relates in particular to a kind of energy-saving power-boost deep-well pump that is used for the rural area field irrigation.

(2) background technique:

In rural water conservancy infrastructure, motor-pumped well is must obligato water conservancy projects, present motor-pumped well characteristics are that well head is little, pit shaft is narrow again dark, the kind machine advances matching used water pump structure and probably is mounted in pump case on the well head, is deep into the axle below the water surface in the pit shaft by being equipped with in the middle of the pump case for the top therewith, fix one on the axle that is in water and turn over water wheels, outer shaft sleeve has the upper end to be tightly connected with pump case, the below cover seal turn under the water wheels with socket, the upper end of axle is fixed with drive wheel.The turning over water wheels what are relevant of this speed that pumps water and below, water outlet soon at most, water outlet is slow at least to turn over water wheels.This water pump structure is simple, and is easy to use.But the water pump of this structure only depends on the water wheels that turn over of below that the promotion of water is risen on the water surface, and when the water surface in the pit shaft was dark, the top drives the power motor of belt wheel rotation or diesel engine must be possessed bigger power and the water in the well could be extracted on the ground.

(3) technological scheme: exist the big shortcoming of power consumption in order to solve present deep-well pump, the utility model provides a kind of promotion well water fast rise, reduce the energy-saving power-boost deep-well pump of the desired power power of deep-well pump, the technical solution of the utility model realizes in the following manner:

A kind of energy-saving power-boost deep-well pump, it comprises that the top is installed in the pump case that has water outlet on the well head, is deep into the axle below the water surface in the pit shaft by being equipped with in the middle of the pump case, be fixed with on the axle that is in water and turn over water wheels, be with on the axle that the upper end is tightly connected with the pump case base, below cover seal turn under the water wheels with socket, the axle the upper end be fixed with drive wheel, wherein be positioned at pump case the axle on be fixed with the water lift impeller by key, impeller keypad.

Below socket in, the axle outside be provided with a support, frame peripheral is that support nest, nest internal fixation have the support card article that is dispersed in around the axle to place restrictions on the sphere of activities of axle, with the axle of support relative position on be with leather sheath and cause the breakage of axle with the prevention axle and the collision of support, leather sheath and support are fixed even.

One impeller stage clip also is housed to stablize impeller on axle, sealing asbestos yarn and asbestos gland are housed between axle and pump case axis hole.

Axle top is held with the heap oblique crank Z and is connected, and heap oblique crank Z bearing is fixed on the pump case head, and gland mother Luo is equipped with the fixed conveyor belt wheel in the axle top.

Good effect of the present utility model is: 1, energy-conservation: because the axle in the middle pump case is gone up the water lift impeller that is provided with, make water in the deep-well be subjected to the thrust with the below of drawing of top, thereby alleviated the power that water wheels bear of turning over of axle bottom greatly, and reduced the power of power source, improved working efficiency; 2, because limiting bracket 14 has been installed on tubular axis, make axle stable in socket, prolonged its working life.

(4) description of drawings:

Fig. 1 is a perspective view of the present utility model.

Fig. 2 is the assembly structure schematic representation of inner each component of the utility model.

(5) below in conjunction with accompanying drawing this reality is done novel being described further.

By Fig. 1, Fig. 2 as can be seen, the utility model comprises that the top is installed in the pump case that has water outlet 34 on the well head, be deep into the axle 1 below the water surface in the pit shaft by being equipped with in the middle of the pump case, be fixed with on the axle that is in water and turn over water wheels 7, being with the upper end on the axle is tightly connected with pump case base 11, below cover seal turn under the water wheels with socket 6, the upper end of axle is fixed with drive wheel 2, the skin cage 8 that the pit shaft lower end also connects is so that go deep in the deep water, in the lower end of skin cage one one-way cock being housed influences the water pump unlatching in case socket leaks, and is being positioned on the axle of pump case by key 15, impeller keypad 17 is fixed with water lift impeller 16; Below socket in, the axle outside be provided with a support 21, frame peripheral is that support nest 20, nest internal fixation have the support card article 19 that is dispersed in around the axle to place restrictions on the sphere of activities of axle 1, with the axle of support relative position on be with leather sheath 22 and cause the breakage of axle 1 with the prevention axle 1 and the collision of support 21, leather sheath 22 is fixedlyed connected with support; One impeller stage clip 13 also is housed to stablize impeller on axle 1, sealing asbestos yarn 14 and asbestos gland 12 are housed between axle 1 and pump case 4 axis holes; Axle 1 top is held 11 with the heap oblique crank Z and is connected, and heap oblique crank Z bearing is fixed on the pump case head, and gland mother Luo 10 is equipped with fixed conveyor belt wheel 2 in axle 1 top.

During use, earlier the pump case chassis is connected with socket, the pump case chassis fixedly is connected on the pit shaft mouth,, connect each parts more successively and get final product installing in the socket of spool packing into of support.
