The utility model is mainly composed of a pump body and a transmission shaft, wherein, the lower part of the pump body is provided with a water inlet; the upper side part of the pump body is provided with a water outlet. The utility model is characterized in that two layers of impellers are arranged on the transmission shaft which is arranged in the pump body; a spiral pressure reducer is arranged between the two layers of the impellers; the transmission shaft is connected with a power shaft by a flexible shaft. The utility model has the effect of high lift (can reach above 62 meters), large water yield, small size, light weight, and convenient maintenance, and furthermore, the utility model can be suitable for various water source conditions. The utility model is the multifunctional novel water pump, and is widely applied to watering and irrigation of villages; the utility model also has the advantages of no need water diversion and convenient operation.
Description
Technical field
The utility model belongs to water fits, particularly a kind of agricultural suction pump.
Background technique
At present, rural area water pump commonly used has three types: centrifugal pump, axial-flow pump, submersible pump.When centrifugal pump uses, must in the intake pipe and the pump housing, inject diversion, with the air emptying, could proper functioning.Effort, time-consuming not only, and because atmospheric effect, can only extract underground about 10 meters water, under the objective condition of lack of water, drawdown now, the using scope of centrifugal pump is very little.Though axial-flow pump can extract the water source than deep layer, and since the restriction of its structure, the groundwater abstraction of can only fixing a point, and move inconvenience, the while pump housing is for a long time in the down-hole of humidity, and is perishable, and inconvenient maintenance.And existing submersible pump can only rely on power supply to be used as power, and is unsuitable for the existing condition in vast rural area, is difficult to apply.Above-mentioned three kinds of water pumps all exist the low shortcoming of water-outlet quantity simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of lift height, novel water pump that water-outlet quantity is big.
The utility model is achieved in that
A kind of novel water pump mainly is made up of the pump housing, transmission shaft, and pump housing bottom is provided with water intake, upper lateral part is provided with water outlet, it is characterized in that: be provided with upper and lower two layers of impeller on the transmission shaft in the pump housing, be provided with the spirality decompressor between two layers of impeller; Above-mentioned transmission shaft links to each other with a line shaft by flexible axle.
After the utility model adopts said structure,, the pressure of water be can increase effectively, pumping lift and water-outlet quantity improved owing to be provided with upper and lower two layers of impeller; The decompressor of setting up between two layers of impeller has been born the pressure of water twist, thereby has improved water lift lift and water-outlet quantity, and the water lift lift has volume effect little, in light weight, easy to maintenance up to more than 62 meters.Adopt the flexible axle transmission simultaneously, length is adjustable, transmitting range is long, transmission efficiency is high, be convenient to install, move, adjust and maintenance, can be suitable for various water conditions, be a kind of multifunctional novel water pump, can be widely used in watering, irrigating of rural well water, river etc., without any need for diversion, easy to use.
Description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
Embodiment
In the accompanying drawing, 1 is that the pump housing, 2 is that impeller, 3 is that water intake, 4 is that water outlet, 5 is that transmission shaft, 6 is that flexible axle, 7 is that line shaft, 8 is that belt pulley, 9 is a decompressor.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
As shown in drawings, the utility model is a kind of novel water pump, mainly is made up of the pump housing 1 and transmission shaft 5, be provided with water intake 3 in the pump housing 1 bottom,, on water intake 3, be provided with filter screen for increasing filtering function, also can be installed into water pipe on the water intake 3 simultaneously, to increase draft.Upper lateral part at the pump housing 1 is provided with a water outlet 4, can install outlet pipe additional in the water outlet 4.Be provided with upper and lower two layers of impeller 2 in the pump housing 1, respectively be provided with 6 blades in the same way on each impeller 2, two layers of impeller 2 all are arranged on the above-mentioned transmission shaft 5, in the same way, rotate with speed.Between upper and lower impeller 2, have additional decompressor 9, this decompressor 9 is installed in type rising in the shape of a spiral on the pump housing 1, the sense of rotation of decompressor 9 is consistent with the sense of rotation of two layers of impeller 2, make that extracting the water that comes up by lower floor's impeller 2 at first enters decompressor 9, rise twist, this part water only forms pressure to decompressor 9, and can not form pressure to lower floor's impeller 2, thereby guarantees upper strata impeller 2 high-lift water lifts.Above-mentioned water outlet 4 is positioned at a side of upper strata impeller 2, flows out by water outlet 4 by the water after 2 pressurizations of upper strata impeller.The other end of above-mentioned transmission shaft 5 links to each other with a flexible axle 6 by thread-shaped extruding linkage structure; Flexible axle 6 can guarantee certain tortuosity, and does not influence normal transmission usefulness; The other end of flexible axle 6 also links to each other with a line shaft 7 by thread-shaped extruding linkage structure, is connected with belt pulley 8 on the line shaft 7, and this belt pulley 8 can directly link to each other with external impetus such as diesel engine, tractor etc.
Be provided with seal arrangement between the above-mentioned transmission shaft 5 and the pump housing 1, rotate for increasing transmission shaft 5 normal axial, axle sleeve can adopt rubber bush bearing, has prevented the corrosion of water.
During use, the pump housing 1 is transferred in deep water or the deep-well, connected outlet pipe on the water outlet 4, belt pulley 8 is high speed rotating under the drive of power externally, drives two layers of impeller 2 high speed rotating by line shaft 7, flexible axle 6, transmission shaft 5.Lower floor's impeller 2 high speed rotating are extracted the water source, and water at first enters decompressor 9, and the current of rotation pass through upwards water lift of upper strata impeller 2 again, are outwards supplied water by water outlet 4, outlet pipe, and water-outlet quantity is big.Owing to be provided with decompressor 9, the water that makes lower floor extract rises twist, only decompressor 9 is formed pressure, and can not influence lower floor's impeller 2, thereby guaranteed effective water lift of upper strata impeller 2, and the water lift lift is up to more than 62 meters.
