Description
Technical field
The utility model relates to deep-well pump technical field, is specifically related to the two-tube single suction jet pump of a kind of deep-well.
Background technique
At present, at equipment up, and the water surface is fetched water when below, usually adopts two kinds of equipment: one is submersible pump, and another kind is exactly deep-well pump.
The working principle of submersible pump is the motor that pump configures is submersible motor, and during work, Pump and Electromotor entirety dives into the water.Owing to being immersed in water, require very high to the sealing of motor etc., product cost is higher, and safeguard, maintenance not easily; Meanwhile, the radial dimension of submersible pump is comparatively large, and the well not easily putting into bore less is fetched water.So the application of submersible pump is subject to larger restriction.
Deep-well pump is the universal machine product that a kind of demand is large, is widely used in many fields of national economy.Current deep-well pump can be divided into again two kinds of forms: a kind of is multistage deep-well pump, and another kind is jet-type deep-well pump.The pump housing and the motor of multistage deep-well pump separate.The pump housing generally adopts multistage centrifugal pump form, dives beneath the water.Motor is then arranged in ground.Adopt coupling to be connected between the pump housing with motor, the axle of pump is very long, usually adopts connection segment.Such deep-well pump there is accuracy of manufacturing and cost of production is high, and install complicated, the shortcomings such as fault is more, inconvenient maintenance, application is also extremely restricted.
And jet-type deep-well pump, because it has simply, facilitate the advantages such as installation and maintenance, use widely in fetching water with current deep-well.
But existing jet-type deep-well pump still has deficiency, specific as follows: current jet-type deep-well pump includes the pump housing and Jet injector, the pump housing is provided with the intake pipe and outlet pipe that are connected with Jet injector, the pump chamber of intake pipe one end and the pump housing is connected, the water outlet of the other end and Jet injector is connected, and the pump chamber of outlet pipe and the pump housing is connected, and the pump housing is also provided with return pipe, the pump chamber of return pipe one end and the pump housing is connected, and the water intake of the other end and Jet injector is connected.In use, the wheel rotation of the pump housing, the water part in pump chamber is pressed to outlet pipe, and a part presses to return pipe, water excavationg pump in outlet pipe is external, and the hydraulic pressure in return pipe enters to be arranged in the Jet injector of deep-well, for Jet injector provides hydraulic pressure, under Jet injector effect, intake pipe is entered again together with the water in deep-well, and then enter the pump housing, so circulate, realize deep-well water intaking.
Due in the course of the work, the pressure that impeller provides only some for by hydraulic pressure to outlet pipe, so the height pumping water is also not high enough, and the another part of the pressure that impeller provides is for setting-out in Jet injector, so the hydraulic pressure obtained in Jet injector is also not high enough, and then cause the suction journey of deep-well pump also not high enough, and, also make the pump water yield of deep-well pump less, and then make outlet pipe have less water-outlet quantity.
In addition, the hydraulic pressure obtained due to Jet injector is not high enough, and intrinsic high pressure nozzle is easily blocked by foreign material, is also the large technical problem that current deep-well pump exists.
So, need one at present badly and larger suction journey and pump water height can be provided, and not susceptible to plugging deep-well pump.
