Abstract
The utility model discloses a two-stage middle open centrifugal pump, and relates to the field of water pumps. The two-stage middle open centrifugal pump comprises a horizontal middle open pump body, a pump cover, a sealing ring, impellers, a shaft, a shaft sleeve as well as a water inlet bearing body and a water outlet bearing body that are fixed at the two ends of the pump body; the two-stage middle open centrifugal pump adopts two-stage impellers, the two-stage impellers are arranged on the shaft oppositely, the two-stage middle open centrifugal pump adopting the above structure has middle flow rate and high-lift parameters, in this way, the deficiency on the parameters is compensated, and the type selection requirement of masses of users can be further satisfied; moreover, the two-stage middle open centrifugal pump has simple structure, and can be maintained, popularized and applied easily.
Description
[technical field]
The utility model relates to a kind of water pump, especially for carrying clear water or non-corrosive liquid medium, and can be suitable for the water pump of factory, mine, the various water supply and sewage work in city.
[background technique]
Centrifugal pump normally is used to carry clear water or non-corrosive liquid medium, and can be suitable for factory, mine, the various water supply and sewage work in city, and still, being seen in the market centrifugal pump is the single-stage impeller normally, and lift is low, reaches about 104m only usually.Moreover, stopping up water pump owing to have impurity usually when carrying clear water or non-corrosive liquid medium, the water pump of prior art need be dismantled inner members such as inlet and outlet pipe and motor, so makes maintenance work difficulty height, and the time is long, and also inconvenience of operation.
Therefore, be necessary to invent a kind of novel centrifugal pump, to overcome above-mentioned defective.
[model utility content]
The purpose of this utility model provides drives centrifugal pump in the twin-stage of flow, high-lift parameter and easy-maintaining in a kind of.For achieving the above object, the technical solution of the utility model is: drive centrifugal pump in a kind of twin-stage, comprise horizontal split pump body, pump cover, seal ring, impeller, axle, axle sleeve and be fixed on the water-in and water-out bearing support at pump housing two ends, it is characterized in that: driving centrifugal pump in the utility model twin-stage is the twin-stage impeller, and both stage impellers is opposing is arranged on the axle.
Drive centrifugal pump in the wherein said twin-stage and also comprise two-stage screw shape volute chamber, described two-stage screw shape volute chamber 180 degree are staggeredly arranged relatively.
Open centrifugal pump intake and discharge opening in the wherein said twin-stage all below the water pump shaft axis, with axis normal in horizontal direction, and suction port and discharge opening are arranged in parallel.
Owing to adopt said structure, drive centrifugal pump in the twin-stage of the utility model and have following beneficial effect:
1. have middle flow, high-lift parameter, so not only filled up the deficiency on the parameter, further satisfy users' type selecting needs simultaneously.
Drive centrifugal pump in the twin-stage of the utility model owing to be the twin-stage impeller, and both stage impellers is opposing to be arranged on the axle, so make that driving centrifugal pump in the utility model twin-stage has good lift performance parameter, also comprise two-stage screw shape volute chamber simultaneously, described two-stage screw shape volute chamber 180 degree are staggeredly arranged relatively, so make that driving centrifugal pump in the utility model twin-stage has good flow performance parameter.
2. simple in structure, for ease of maintenaince, be easy to apply
Drive centrifugal pump in the twin-stage of the utility model only owing to adopt the horizontal split pump body, need not during maintenance to dismantle inlet and outlet pipe and motor, easy to maintenance, simple.And comparing with existing centrifugal pump does not increase baroque component, in the reliability that improves pump work, makes and drives centrifugal pump in the twin-stage and have longer working life.Overall structure is simple, be easy to apply.
[description of drawings]
Fig. 1 is a structural representation of driving centrifugal pump in the utility model twin-stage.
The element numbers explanation:
The pump housing-19, pump cover-16, pump shaft-4, axle sleeve-14, impeller-15, bearing part-13, two-stage screw shape volute chamber-2
[embodiment]
Be further described driving centrifugal pump in the utility model twin-stage below in conjunction with drawings and Examples.
Drive centrifugal pump in the utility model twin-stage, be used to carry clear water or non-corrosive liquid medium, and can be suitable for factory, mine, the various water supply and sewage work in city, but its medium temperature must not be above 80 ℃.
Please refer to shown in Figure 1, drive centrifugal pump in the utility model twin-stage and comprise the pump housing 19, the described pump housing 19 is the horizontal split pump body, so, need not to dismantle inlet and outlet pipe and motor during maintenance, easy to maintenance, be arranged at topmost pump cover 16, be arranged at the pump shaft in the pump housing or be called axle 4, be arranged at pump shaft or be called axle both sides 4 about axle sleeve 14, be arranged in the pump housing middle part and be positioned at twin-stage impeller 15 on the part pump shaft, and both stage impellers 15 opposing being arranged on the axle 4, theoretically, end thrust reaches balance substantially; Be provided with and be fixed in the water-in and water-out bearing part 13 of the pump housing 19 both sides respectively, the lower end that is arranged at the pump housing 19 middle parts, impeller 15 is a two-stage screw shape volute chamber 2, this two-stage screw shape volute chamber 2 is 180 degree and is staggeredly arranged relatively, and layout can reduce radial force to the caused radial vibration of bending shaft effect like this.
That is, drive centrifugal pump in this practical twin-stage, comprise stator and rotor two big parts, stator component has the pump housing, pump cover, bearing support, seal ring etc.Rotor part has axle, impeller, axle sleeve etc.Pump intake and discharge opening are all opened in the utility model twin-stage below the shaft axis of centrifugal pump, with axis normal in horizontal direction, and suction port and discharge opening be arranged in parallel (indicating among the figure).See that from driving end pump is the clockwise direction rotation.Drive centrifugal pump in this practical twin-stage, compare with middle-opening pump commonly used, as SH type, S type and EOTS type, its performance parameter is big flow, low lift.And drive centrifugal pump in this practical twin-stage is that DKY type pump performance is middle flow, high-lift parameter, and DKY delivery side of pump lift can reach 600m, and this satisfies the high-lift need of user to a certain extent.So not only fill up the deficiency on above-mentioned three kinds of model parameters, further satisfied users' type selecting needs simultaneously.
Equally, in using this practical twin-stage, open and need in the process of centrifugal pump bearing with grease or thin oil lubricant.
The description of above preferred embodiment makes those skilled in the art can make or use the present invention.These embodiments' various modifications are conspicuous for a person skilled in the art, and Ding Yi General Principle can be applied to not deviating among other embodiment the spirit or scope of the present invention here.Therefore, the embodiment that the present invention is not limited to illustrate here, and will meet and the principle and the novel feature the most wide in range consistent scope that disclose here.
