Abstract
The utility model discloses a double water pump, comprising a pump body 1 and a pump shaft 3, which are assembled; the utility model adopts a correlate independent centrifugal pump assembly, and namely, the same pump shaft is provided with two centrifugal pumps having opposite rotating direction before assembled. One water pump of the double water pumps has the function like a water turbine, liquid enters the water pump from the discharge opening of the usual centrifugal pump and flows out from the water suction opening, and an impeller is pushed to rotate reversely, the other water pump is driven to operate normally by a transmission shaft, and namely, the liquid enters the water pump from the water suction opening of the usual centrifugal pump and flows out from the discharge opening. The utility model can be arranged in the liquid process pipeline with a throttling and a pressure throttling devices; the water pump can be used singly by that the water pump is driven by the recovered energy water turbine, or the double water pump can be used by that the double water pump is connected with the outside power force in series or in parallel. The utility model can achieve the purposes that the energy is saved, the process and the working condition are improved, and the requirements of the process system can be met.
Description
The utility model relates to different application fields such as a kind of industry, agricultural, urban operating mechanism, has the combined type double water pump that uses in throttling, the joint pressure device liquid process pipeline.
In the existing background technique, twin-stage or multi-level combined pump body are varied structure, as having introduced two kinds of relay pumps in China model utility CN87202219 and the CN88218346.4 patent specification respectively.This relay pump is the assemblying body of a kind of axial-flow pump and centrifugal pump, both has been provided with identical aial flow impeller of sense of rotation and receded disk impeller on same pump shaft, and flow is big, lift is high so its usability shows as.The combinations thereof pump is only limited to carries the single liquid medium to use.
The disclosed combined type double water pump of the utility model, its structural type is all different with above-mentioned prior art with application, the purpose of this utility model provides a kind of combined centrifugal double water pump, both on same pump shaft, be equipped with the combination before the opposite centrifugal pump of sense of rotation, constitute interrelated and separate centrifugal pump assemblying body.
Double water pump provided by the utility model is assembled into one by the pump housing and pump shaft, its structural feature is that said double water pump adopts a kind of centrifugal pump assemblying body, both on same pump shaft, be equipped with the combination before the opposite centrifugal pump of sense of rotation, constitute interrelated and separate combined centrifugal pump.Wherein a water pump is made water turbine, make liquid from the discharge opening of common centrifugal pump enter, the water sucking mouth flows out, the pump counter-rotating drives another water pump by the transmission pump shaft, make it just transfer to merit, both liquid from common centrifugal pump suction port enter, discharge opening spues, the pump housing of two water pumps reversing of position mutually uses.
Above-mentioned double water pump can be formed one with two pump housings by same pump shaft, also can be assemblied in the bearing spider both sides by same pump shaft.According to using on-the-spot needs, be provided with one group of preceding opposite centrifugal pump of sense of rotation of combination on the same pump shaft at least, derive many water pumps assemblying body by double water pump basic structure.
Above-mentioned many water pumps of double water pump formula assemblying body can be selected the centrifugal pump of of the same type centrifugal pump or similar model for use, is used for the single liquid medium or non-single liquid medium working environment uses.Double water pump can be made into horizontal or vertical double water pump, and its setting angle is any.
At present, in fields such as industry, agricultural, urban operating mechanisms, many throttlings, joint pressure device are arranged, in the liquid process pipeline as dropping valve, throttle valve, consumed many energy in vain, some liquid needs to increase flow or pressure with double water pump near it but can reach in its vicinity or by the process pipe transformation.Can adopt the said double water pump of the utility model in this place, reclaim the energy of waste, add the use new energy not increase or to reduce.When the water turbine (counter-rotating water pump) that reclaims the waste energy, when the drive water pump reaches technological requirement, double water pump can use separately, as can not satisfy technological requirement the time, can select water pump and double water pump series connection or in parallel use that common electric power or internal-combustion engine drag, reach energy saving, improve the technology operating mode, satisfy the requirement of process system.
This double water pump especially is fit to be installed in and has throttling, saves pressure device and regime flow is arranged and the long-term system of pressure uses.As existing normal-pressure hot-water boiler heating circulation system, adopt above-mentioned double water pump can solve energy consumption height, the backwater wayward two big technical barriers that the present normal-pressure boiler circulatory system exists simultaneously effectively.
The manufacturing of double water pump does not have any specific (special) requirements, and existing production water pump works, anti-corrosive pump factory be the energy processing and fabricating all, and the unit that possesses the assembling water pump all can assemble.The utility model is actual to be that the inconsistent water pump of two sense of rotation is assembled into one.
Introduce two kinds of embodiments of the utility model below in conjunction with accompanying drawing.
Fig. 1 is the horizontal double water pump structural representation of the utility model.
Fig. 2 is the vertical double water pump structural representation of the utility model.
Among the figure: 1. the pump housing 2. bearing spiders 3. transmission shafts
4. double water pump base 5. bearing fixing framves
Fig. 1, double water pump preparation process shown in Figure 2 and assembly structure are identical with current technology and fit, just select for use two different centrifugal pumps of preceding two sense of rotation of combination to combine.The small capacity double water pump can be without base, fixing frame, and directly is fixed on the bearing spider, is connected and fixed by water pump and pipeline.
