Abstract
The invention discloses a submersible electric pump for realizing jumping working conditions, which comprises a submersible motor (I) and a submersible pump (II), wherein the submersible pump consists of an upper pump (1) and a lower pump (2); the submersible electric pump is characterized in that a water sucking mouth (3) of the upper pump is communicated with the outside and one pipe port of a water outlet (5) of the lower pump through pipelines respectively, and the pipelines communicated with the outside and the water outlet (5) of the lower pump are provided with control valves respectively; another pipe port of the water outlet (5) of the lower pump is connected with an overall water outlet through a pipeline which is provided with a control valve; a water outlet (4) of the upper pump is connected with the overall water outlet through a pipeline; and a water sucking mouth (6) of the lower pump is connected with the outside through a pipeline. The submersible electric pump not only can realize the jumping working conditions under the change of external environments and improve the timeliness, but also can ensure that the prior submersible electric pump realizes multiple functions through transformation and reduce disaster relief material reserve.
Description
Technical field
The present invention relates to a kind of Submerged Motor Pumps, particularly a kind of being widely used in the on-the-spot emergency drainage in all kinds of mines, and can adapt to the Submerged Motor Pumps of the operating condition-jumping of different operating modes fast and efficiently.
Background technique
Along with coal mining constantly extends to the deep, in the emergency drainage process of existing mine, run into such situation through regular meeting: speedily carry out rescue work the initial stage, because ponding is many, require big flow draining to solve the danger that flood is brought, generally can select double pump operation in parallel for use, lift is low but flow is big; And enter the middle and later periods of speedily carrying out rescue work, and because ponding is crossed dark and the tunnel dwindles, it is high-lift that operation in parallel is difficult to realize, at this moment just adopts the double pump work in tandem, water improves lift through the secondary booster of double pump.The change of working environment means the transition of Submerged Motor Pumps operating mode.In the prior art, the transition of this operating mode requires double pump to be converted to work in tandem by operation in parallel, and the down-hole removes and installs difficulty, wastes time and energy, and has influenced the ageing of rescue and relief work; Simultaneously, reduce the working efficiency of Submerged Motor Pumps, increased the deposit of disaster relief supplies.
Summary of the invention
Purpose of the present invention provides a kind of Submerged Motor Pumps that adapts to the operating condition-jumping of different operating modes at existing deficiency in the above-mentioned prior art just.This Submerged Motor Pumps can not only be realized operating condition-jumping under extraneous environment change, improved ageingly, and can make existing Submerged Motor Pumps realize a tractor serves several purposes by transformation, reduces the disaster relief supplies deposit.
Purpose of the present invention can realize by following technique measures:
The Submerged Motor Pumps of operating condition-jumping of the present invention comprises submersible motor and submersible pump, submersible pump is made up of last pump and following pump two-part, last pump water sucking mouth is connected with a mouth of pipe extraneous and that pump the mouth of a river down respectively by pipeline, and is respectively arranged with control valve being communicated with extraneous and pumping down on the pipeline at the mouth of a river; Another mouth of pipe that pumps the mouth of a river down is connected with total water outlet by pipeline, and this pipeline is provided with control valve; On pump the mouth of a river and be connected with total water outlet by pipeline; Following pump water sucking mouth is connected with extraneous by pipeline.
Working principle of the present invention is as follows:
Under the normal condition, last pump water sucking mouth control valve is opened, pumping the mouth of a river down also opens with the control valve on the pipeline that total water outlet is connected, only close the control valve on closing the pump water sucking mouth and pumping the pipeline that the mouth of a river is connected down, at this moment about pump independence parallel operation, water enters the pump housing from the water sucking mouth of two pumps respectively, after pump housing impeller boosts, the water outlet of two pumps converges to total water outlet discharge through water outlet separately, and the Submerged Motor Pumps lift is constant, and the single pump of flow-rate ratio doubles; Control valve is closed when last pump water sucking mouth, pumping the mouth of a river down also closes with the control valve on the pipeline that total water outlet is connected, during control valve on only open going up the pump water sucking mouth and descending to pump the pipeline that the mouth of a river is connected, upper and lower pump is realized series connection, and water enters from following pump water sucking mouth, and the pump of flowing through down boosts, again under pump the mouth of a river and flow into to go up pump by pipeline, current arrive total water outlet discharge through behind the last pump secondary booster from pumping the mouth of a river, and the Submerged Motor Pumps lift promotes one times.
Beneficial effect of the present invention is as follows:
When on-the-spot emergency drainage environment changes, upper and lower pump connection need not remove and install, only need to open and close by the independent of control valve to three respectively, can realize the Submerged Motor Pumps conversion of the series, parallel work pattern of pump up and down, can realize the operating condition-jumping of Submerged Motor Pumps, reduced operation and changed and remove and install the time, time saving and energy saving, improved ageing.In addition, also can enlarge the application area of Submerged Motor Pumps, can make the existing Submerged Motor Pumps upgrading of China, a tractor serves several purposes reduces unnecessary material stock.
