Abstract
The utility model relates to a multi-stage centrifugal multifunctional water pump for conveying clear water and liquid of which the physical and chemical properties are like water under liquid, in pipelines and ordinary water pumps. The multi-stage centrifugal multifunctional water pump is characterized in that a flow guiding cavity of the multi-stage centrifugal multifunctional water pump forms a water way surrounding a motor. The multi-stage centrifugal multifunctional water pump has simple structure and multiple purposes and is convenient and flexible to be carried and moved. The utility model can adapt to the requirements of different environments and operating conditions and can be used reliably above and under liquid.
Description
The utility model relates to a kind ofly be used under the liquid, multistage centrifugal multifunctional water pump that the conveying clear water of pipeline and conventional pump water and physics, chemical property are similar to the liquid of water.
The centrifugal water pump that factory uses is of a great variety.Can be divided into common water pump, Under Water Pumps, pipeline mounted pump etc. by the characteristics that pump had.Can be divided into single entry pump and double suction pump by suction.Number by impeller can be divided into single-stage pump and multistage pump etc.For example: bearing industrial water, the common centrifugal water pump of the conveying task of cooling water, most widely used is single-stage cantilever type centrifugal water pump, the double suction, single-stage centrifugal water pump, multi-stage centrifugal pump etc., they are by the pump housing.Compositions such as impeller, arbor, transmission shaft are equipped with motoring, pump water behind the pump priming of pouring water.This water pump general work condition, installation conditions are relatively carved and asked, and be fixing, inconvenient mobile operating, and can only do single use waterborne.Under Water Pumps in factory as a kind of process pump or process pump, be widely adopted, it is to be integral by the pump housing, impeller, motor combination, be directly installed under the liquid, relatively simple for structure, shaft sealing is less demanding, be convenient to move, installation requirement is not high, but because motor radiating relies on is the liquid that is transferred, thereby only be suitable for using under water.In view of this miscellaneous centrifugal water pump purposes is single, and using scope is narrow, can not use by a pump more.
Purpose of the present invention design exactly one simple in structure, it is flexible to carry conveniently moving, can adapt to different environment, the demand of operating mode, the multifunctional water pump that all can reliably use on the liquid, under the liquid.
The multifunctional water pump that the utility model is chatted is the motor by the pump center, upper and lower two impellers, the arbor that connects motor and two impellers, interior motor cover and outer pump cover form the upper and lower end cap of a diversion cavity, the shell of pump, have the base of relaying relay water inlet interface, the water outlet flow-guiding mouth on top is formed.The diversion cavity that the diversion cavity of upper and lower end cap and pump case and motor housing are formed forms the water conservancy diversion water cavity of an encirclement motor.After turn-on current, motor rotation drives arbor, the both stage impellers entry into service, and water sucks first order impeller by the base water intake, sends into the water conservancy diversion water cavity with the pressure lift of first order impeller, is sucked and is extruded by second level impeller again.Because water passes through from the motor periphery, the heat that motor rotation produces is taken away thereupon.
Multifunctional water pump described in the utility model can also can be used as submersible pump usefulness under water as pump water usefulness waterborne, can be used as the relaying booster pump and uses, and also can dock with civilian hand motor-pumped well to carry out counterpart and draw water.This pump structure is simple, easy to usely flexibly is applicable to the demand of varying environment, different operating modes, on the liquid, under the liquid, pipeline all can reliably use, and reaches the multi-functional purpose of a pump.
Embodiment:
The multifunctional water pump structure of the utility model being chatted below in conjunction with accompanying drawing is described in detail:
Accompanying drawing: the multifunctional water pump structural representation, wherein:
1. base 2. first order impellers 3. lower end caps
4. pump case 5. motor housings 6. rotors
7. diversion cavity 8. upper end caps 9. second level impellers
10. water outlet flow-guiding mouth 11. stators 12. arbors
13. bearing 14. seal rings 15. power lines
16. motor windings 17. relaying relay interfaces
18. diversion cavity
In pump case 4, settle a motor that constitutes by stator 11, rotor 6, motor windings 16, motor housing 5, make and form a diversion cavity 7 between motor housing 5 and the pump case 4.At upper end cap 8 of the top of motor peace, lower end cap 3 of bottom peace, its double layer construction that is configured to a diversion cavity 18 of middle formation, internal layer just in time coincide with motor housing 5, skin just in time coincide with pump case 4, makes diversion cavity 7 and diversion cavity 18 form the water conservancy diversion water channel of a UNICOM.Arbor 12 passes rotor 6 and upper end cap 8, and 3, one of lower end caps link to each other with the second level impeller 9 that is positioned at water outlet flow-guiding mouth 10, and the other end links to each other with the first order impeller 2 of bottom.Between arbor 12 and upper and lower end cap 8,3, seal ring 14 and bearing 13 are housed.Relaying relay interface 17 is installed in the base 1, communicates with the diversion cavity of lower end cap.The top that water conservancy diversion water outlet 10 is installed in the pump housing communicates with the diversion cavity of lower end cap.Power line 15 is contained on the pump case.
