Abstract
The combined double water pumps include two bump body and one shaft and it features that it utilizes parallel and independent centrifugal pump combination with two opposite-direction rotary centrifugal pumps mounted on the identical shaft. In the double pumps, one acts as a hydraulic turbine in which liquid flows from the outlet to the inlet so as to drive inversely the vane wheel and drive the other pump to rotate in front direction. The said double water pumps may be installed in liquid pipeline and driven by energy-recovering turbine and may be used seriesly or parallelly.
Description
The present invention relates to different application fields such as a kind of industry, agricultural, urban operating mechanism, have 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 respectively in China invention CN87202219 and the CN88218346.4 patent specification.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.
Combined type double water pump disclosed by the invention, its structural type is all different with above-mentioned prior art with application, the purpose of this invention is to provide 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 present invention 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 non-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 present invention 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 present invention below in conjunction with accompanying drawing.
Fig. 1 is the horizontal double water pump structural representation of the present invention.
Fig. 2 is the vertical double water pump structural representation of the present invention.
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.
