Abstract

The utility model relates to a JS deep-well pump, particularly a pump body, composed of a pump head, a drive shaft, a water lifting pipe, a middle pipe, a pump body and a water absorbing nozzle. The pump head is fixed with the upper end of a first pump body through the lifting pipe, the lower end of the first pump body is fixed with the upper end of a second pump body through the middle pipe, and a plurality of pump bodies can be arranged as required. The utility model has the advantages of high efficiency, high lift head, strong applicability, simple structure and easy fabrication, being a product for replacing JS deep-well pumps.

Description

Booster pump

The utility model relates to a kind of JS deep-well pump, the particularly pump housing.

The JS deep-well pump is mainly chewed by pump head, transmission shaft, lifting pipe, the pump housing, suction sleeve and suction and is formed at present, pump head is fixed by the lifting pipe and the pump housing, the pump housing is made up of many groups impeller and drain body, the lower end of the pump housing is chewed fixing by suction sleeve and suction, the power output hollow shaft of the upper end of transmission shaft and pump head is fixed, and the impeller that the lower end is passed in the lifting pipe and the pump housing is fixed.Transmission shaft high speed rotating impeller high speed rotating, water is drunk up under action of centrifugal force.The lift of every group of impeller and drain body is 8.7 meters, and after a plurality of combinations, because transmission efficiency is low, so actual lift can not get the result of addition, and difference is far.Because the impeller and the drain body group number of the pump housing assemble when dispatching from the factory, so how dark well will select great pump, conformability is poor.

The purpose of this utility model is to design a kind of lift height, the suitable strong deep-well pump of property.

The utility model is achieved in that it is by pump head, transmission shaft, lifting pipe, intervalve, the pump housing, composition is chewed in suction sleeve and suction, pump head is fixed by the upper end of the lifting pipe and a pump housing, the rotatingshaft upper end is fixed with the hollow shaft of pump head, impeller in the lower end and the pump housing is fixed, the lower end of transmission shaft is by the rubber bush bearing supporting that is fixed on the drain body inner hole wall, the lower end of the pump housing is fixing with a pump housing upper end again by intervalve, another rotatingshaft is respectively with last, the impeller of lower end is fixed, can adorn a plurality ofly as required, fixing getting final product chewed in the pump housing bottom and suction.

The utility model compared with prior art has following advantage: (1) has intervalve therebetween because the pump housing separately is not assembled together, so each pump housing, can both obtain sufficient feedwater, the transmission efficiency height, and lift has been improved greatly; (2) because the pump housing is separately to assemble, how much just dress how much, so adaptability is strong; (3) power is constant outside, under the constant situation of lift, can reduce the number of the pump housing, and cost has also just reduced naturally; (4) simple in structure, easy for installation, easily manufacturing is the update product of JS deep-well pump.

Be elaborated below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model partial enlarged drawing.

The utility model is chewed 5 by pump head 1, transmission shaft 7, lifting pipe 2, intervalve 4, the pump housing 3 and suction and is formed, wherein pump head 1 is fixed by the upper end of the lifting pipe 2 and a pump housing 3, the hollow shaft of transmission shaft 7 upper ends and pump head 1 is fixed, impeller 9 in lower end and the pump housing 3 is fixed by screw thread, this screw thread is a left hand thread, and the lower end of transmission shaft 7 is by rubber bush bearing 8 supportings that are fixed on drain body 6 inner hole walls.The lower end of the pump housing 3 is fixed with the pump housing 3 upper ends again by intervalve 4, another transmission shaft 7 respectively with the pump housing 3 of upper and lower end in impeller 9 fix by screw thread, wherein the upper and lower end of transmission shaft 7 all is a left hand thread.Said structure can be adorned a plurality of as required, and the pump housing 3 is bottom chewed 5 with suction and fixed.

Claims
