Description

The flexible axle boost pump

Technical field

The utility model belongs to the technical field of multistage pump, is specifically related to a kind of flexible axle boost pump.

Background technique

The water pump of Chu Shouing is large in the variety in the market, but because of the generally decline of level of ground water in recent years, Ordinary Centrifugal Pumps can't be used because of vacuum sucking low (generally having only about 7 meters).Some the no electricity in area or short of electricity, though some area has, but because of farmland area excessive, each well location fails all to reach power supply facilities, what have has electric area also big down less than in the well because of the submersible pump overall volume, Liaoning particularly, Jilin, the three provinces in the northeast of China, Heilungkiang, for a lot of wells have been beaten in drought resisting, the underground water of this area is rich pool, and abundant water reduces for making the well-digging cost, the well casing major part of usefulness all is the plastics well casing of Ф 150mm now, and static water level is all at 10 meters～15 meters, and journey is low can't be used centrifugal pump because of inhaling, and submersible pump is put greatly less than (profile is greater than Ф 150mm) in the well because of profile.

Chinese patent ZL98215358.9 discloses a kind of multipole flexible shaft water pump, constitute by last lower pump body, flexible axle, flexible pipe, conduit pipe, conduit pipe joint, hose support, its upper pump casing is a horizontal pump, the flexible axle that connects the upper and lower pump housing need bend when entering well, though there is hose support to support, but cause power loss bigger, and the pump assembly complex structure, install and use inconvenience.

Summary of the invention

The utility model is in order to solve the demand that conventional vacuum pump in the prior art or submersible pump can not adapt to present agricultural irrigation, and the loss of existing flexible axle pump power is bigger, and complex structure is installed inconvenient problem, and a kind of flexible axle boost pump is provided.

The utility model adopts following technological scheme to realize:

A kind of flexible axle boost pump comprises pump, following pump and connect the two flexible axle, the flexible shaft jacket flexible pipe, and flexible pipe peripheral hardware conduit pipe is characterized in that described to go up pump be vertical pump.

Described pump external diameter down is≤Ф 133mm.

Last pump comprises the vertical pump housing, install pump impeller in the vertical pump housing, axle head is installed anti-reversing belt pulley on the last pump impeller axle at last pump impeller center, lower shaft end is connected with flexible axle by the minor axis of rectifying a deviation certainly, vertical pump housing bottom by on be connected on connecing dish, bearing bracket, conduit pipe joint and conduit pipe.

Following pump comprises the cartridge type pump housing, pump impeller, guide plate under installing some groups in the cartridge type pump housing, axle head is connected with flexible axle on the following pump impeller axle of following pump impeller, and cartridge type pump housing upper end is connected with the conduit pipe lower end by bearing spider, and the lower end cap of cartridge type pump housing lower end is by being connected with water strainer along dark pipe.

Flexible axle boost pump described in the utility model is on the basis of other water pumps, reaches profile diameter and minimizes (going into well part profile maximum diameter), adapts to the well head maximization, has solved the unreasonable water lift equipment blank of thinking of little well head under the equal flow.

The utility model main structure is inhaled pump in the supercharging by helping; pump under the power-assisted, its Connecting format are tandem compound, by the flexible axle transferring power; flexible axle is by special flexible pipe protection; flexible pipe places conduit pipe, and by various terminal, bearing support, bearing cap, joining shaft, the minor axis of rectifying a deviation is connected with upper and lower certainly; form a whole; last pump is a vertical single stage centrifugal pump, utilizes impeller shaft that power is passed to down pump by flexible axle, and following pump is a single suction multistage centrifugal submersible pump.Flexible axle power-assisted water pump power is extensive, but dynamoelectric dual-purpose, flow is big, and the lift height is applicable to the well casing of different bores and water level seriously descends regional and nothing is electric, power outage area, is to substitute centrifugal pump, submersible pump, the desirable water lift of particularly small-bore well.

The relative prior art of the utility model has following beneficial effect:

1, Applicable scope is extensive;

2, mating power is wide in variety, but dynamoelectric dual-purpose;

3, parts such as little, in light weight, the impeller of volume, stator, conduit pipe, water strainer adopt engineering plastics, to mould Dai Gang, weight reduction, energy saving;

4, simple to operate, conveniently moving down pumps into water and can go up water, need not add diversion, saves time, laborsaving easy to use;

5, investment is little, the field irrigation cost is low, the lift height, and pressure is big, is the desirable water lift of the water-saving spray engineering of current country promotion;

6, the life-span is long, easy to maintenance; because of upper and lower pump is connected by the minor axis of rectifying a deviation certainly; solved upper and lower concentric topic together, also protected Great Wall Software's axle not to be damaged in the ordinary course of things, joint, flexible axle lower end has increased expansion device; the bending of having avoided Great Wall Software's elongate axis to cause; flexible axle adds senior hydraulic grease by the flexible pipe protection of special use in the flexible pipe, the flexible pipe two ends are sealed with mechanical seal; make flexible axle that good working environment be arranged, the flexible axle of the life-span of flexible axle than the specialty regulation improved three times working life.

In a word, the flexible axle boost pump has overcome centrifugal pump, and the narrow limitation that submersible pump is intrinsic integrates the two advantage, and also because of flexible axle boost pump external diameter diameter is little, it is long-pending big to have only Ф 133mm to overcome other pump lower pump bodies, the narrow limitation that using scope is little.
