Abstract
The utility model relates to an electric double water pump, comprising a pump body and a pump shaft, which are assembled into a whole. The utility model is characterized in that the electric double water pump adopts a correlate independent centrifugal pump assembly, namely, the same pump shaft is assembled with two centrifugal pumps which have the opposite rotating directions before assembled, and the double water pump is driven by a motor. One water pump of the double water pump has the function like a water turbine, the liquid enters the centrifugal pump from the discharge opening of the centrifugal pump and flows out from the suction opening, and the other water pump is driven to realize the positive rotating operation by a transmission shaft. The utility model is arranged in the pipeline where the liquid has a definite fall, the liquid is raised by the recovered energy of the water pump, and the purpose of saving energy and improving the working condition can be achieved.
Description
The utility model relates to different application fields such as a kind of industry, agricultural, urban operating mechanism, and it has the electronic double water pump that uses in the process pipe of certain free drop liquid.
In the existing background technique, twin-stage or multi-level combined pump body are varied structure, as China model utility CN87202219) and the CN88218346.X patent specification in introduced two kinds of relay pumps respectively.This relay pump belongs to a kind of axial-flow pump and centrifugal pump assemblying body, both has been provided with identical aial flow impeller and the receded disk impeller of sense of rotation before the combination on same pump shaft, its usability show as flow greatly, make liquid rise to a high position from low level, the lift height.Existing all kinds of machineries, characteristics are that the systemic circulation pump all can not withdrawal liquid backflow potential difference energy.
The disclosed electronic double water pump of the utility model, its structural type is different with above-mentioned prior art, the purpose of this utility model provides the electronic double water pump of a kind of combined centrifugal, both on same pump shaft, be equipped with the combination before the opposite centrifugal pump of sense of rotation, form interrelated and separate centrifugal pump assemblying body, and drive the double water pump rotation as auxiliary power by motor.
The bright double water pump of electricity provided by the utility model is assembled into one by the pump housing and pump shaft, its structural feature is that said electronic double water pump adopts a kind of centrifugal pump assemblying body, both on pump shaft, be equipped with the combination before the opposite centrifugal pump of sense of rotation, constitute interrelated and separate combined centrifugal pump, and rotate by the motoring pump shaft.Wherein a water pump effect is similar to water turbine, make liquid from the discharge opening of common centrifugal pump enter, the water sucking mouth flows out, pump counter-rotating drives another water pump by the transmission pump shaft, makes it just transfer to merit, both liquid from common centrifugal pump suction port enter, discharge opening spues.Above-mentioned double water pump can be applied among the normal-pressure boiler circulatory system, the condensed water circulatory system, utilize high-order liquid return potential difference, promote the water turbine work done in the double water pump, drive another water pump lifting liquid in the double water pump, motor drives pump shaft as auxiliary power and rotates, and overcomes the loss of backflow potential difference portion of energy.
Above-mentioned double water pump can be formed one with two pump housings by same pump shaft, and same pump shaft is axle both, and also two axles are fused by shaft joint.The pump housing of above-mentioned double water pump is assemblied in motor output shaft one side or both sides by 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 above-mentioned 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.Double water pump can directly drag pump shaft by motor and rotate, and also can pass through to rotate by driving pump shaft between belt pulley, chain or gear.
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 driving water pump and reaching technological requirement, double water pump can use separately, as can not satisfy technological requirement the time, the double water pump that can select common electric power or internal-combustion engine to drag reaches energy saving, improves the technology operating mode, satisfies the requirement of process system.
This electronic 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.Use at existing cooling recirculation system, can effectively utilize liquid drop energy, thereby reduce pump motor power, save the energy, guarantee circulatory system proper functioning.
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 two rotating forces are assembled into one to inconsistent water pump.
Introduce two kinds of embodiments of the utility model below in conjunction with accompanying drawing.
Fig. 1 is the horizontal electronic double water pump structural representation of the utility model.
Fig. 2 is the utility model vertical electric double water pump structural representation.
Fig. 1, electronic 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 centrifugal pump body 1 that sense of rotation is opposite before two combinations is assembled into one by motor 2 and pump shaft 3, and the pump housing 1 is positioned at motor 2 both sides.In the above-mentioned electronic double water pump, the blade wheel structure chi difference of each centrifugal pump.
