Abstract
The utility model relates to a vertical centrifugal pump in rigid connection, which comprises a pump body, a pump cover, an impeller, a sealing ring, a shaft, a sealing gland, a sealing component and a connecting rack, wherein the pump cover and the connecting rack are fixedly arranged on the pump body, the shaft penetrates through the sealing gland, the sealing component and the impeller from top to bottom, the upper end of the shaft is connected with a rigid coupling to fix the position of the shaft, and the impeller is sealed with the pump body and the pump cover through the sealing ring. The vertical centrifugal pump is characterized in that the lower end of the shaft is provided with a shaft sleeve matched with a sliding bearing, has the advantages of compact structure and good reliability, and is operated stably.
Description
Technical field
The utility model belongs to the industrial pump field, particularly relates to a kind of rigidly connected vertical centrifugal pump.
Background technique
At present, the structure characteristic of rigidly connected vertical centrifugal pump is to be rigidly connected by coupling between pump shaft and the motor shaft, radial force and axial force that the rotor part weight in pump group when running and impeller rotation are produced the impeller rear overhang be housed in pump on the axle, so can only be carried by motor bearings.This structural type can only be applicable to the pump of small dimension.If pump size is big or rotating speed still adopts this structure when higher, the power that acts on the motor bearings may surpass its bearing capacity, promptly can cause the motor bearings heating, make bearing wear easily, and then cause other damage of components of pump group, cause whole unit operation not steadily, vibration and noise are big even break down.So develop and a kind ofly be applicable to big specification, rotating speed height, operate steadily, scheme simple and compact for structure is necessary.
Summary of the invention
The utility model provides a kind of compact structure for solving the technical problem that exists in the known technology, operates steadily, the rigidly connected vertical centrifugal pump of good reliability.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of rigidly connected vertical centrifugal pump, comprise the pump housing, pump cover, impeller, seal ring, axle, sealing gland, black box, hitch, pump cover and hitch are packed on the pump housing, axle passes sealing gland, black box, impeller from top to bottom, the upper end is by being connected and fixed its position with rigid coupling, seal by seal ring between the same pump housing of impeller, the pump cover, it is characterized in that: axle sleeve is equipped with in the lower end of axle, and axle sleeve cooperates with sliding bearing.
The utility model can also adopt following technological scheme:
The lower end surface of axle also is fixed with wheel hub cover, the edge of wheel hub cover and axle sleeve adjacency.
Advantage and the good effect that the utlity model has are:
Because the utility model adopts technique scheme, promptly pump shaft passes sealing gland, sealing, impeller and axle sleeve from top to bottom, and fixes with wheel hub cover; The upper end is determined to realize axially locating by motor bearings in its position by being connected with rigid coupling; The lower end cooperates with sliding bearing after axle sleeve is housed, and realizes radial location; This design can balance be rotated the radial force that is caused by rotor part, and that has avoided that axle produced thus radially wobbles, and has protected the damage of black box, axle and other component effectively.Wherein the component on rotor assembly and the axle can integral body be pulled out, and properties of journal bearing lubricated also can be taken out from the bottom, is convenient to the replacing and the maintenance of component.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial structurtes figure at the utility model properties of journal bearing lubricated place.
Among the figure: 1, the pump housing; 2, pump cover; 3, impeller; 4, seal ring; 5, axle; 6, sealing gland; 7, black box; 8, axle sleeve; 9, wheel hub cover; 10, properties of journal bearing lubricated; 11, hitch; 12, rigid coupling.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 to Fig. 2, a kind of rigidly connected vertical centrifugal pump, comprise the pump housing 1, pump cover 2, impeller 3, seal ring 4, axle 5, sealing gland 6, black box 7, hitch 11, pump cover 2 is packed on the pump housing 1 by bolt or double-screw bolt with hitch 11, axle 5 passes sealing gland 6 from top to bottom, black box 7, impeller 3, the axle the upper end by with rigid coupling 12 be connected and fixed the axle the position, impeller 3 is with the pump housing 1, seal by seal ring 4 between the pump cover 2, axle sleeve 8 is equipped with in the lower end of axle 5, axle sleeve 8 cooperates with sliding bearing 10,10 cool off and lubricated flushing and the cooling that seals from hyperbaric chamber diversion to sealing part simultaneously from the hyperbaric chamber diversion to properties of journal bearing lubricated during work.
The lower end surface of axle 5 also is fixed with wheel hub cover 9, and the edge of wheel hub cover 9 and axle sleeve 8 adjacency prop up axle sleeve 8, prevents that axle sleeve 8 from axial float taking place.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
Claims (2)
1. rigidly connected vertical centrifugal pump, comprise the pump housing, pump cover, impeller, seal ring, axle, sealing gland, black box, hitch, pump cover and hitch are packed on the pump housing, axle passes sealing gland, black box, impeller from top to bottom, the axle the upper end by with rigid coupling be connected and fixed the axle the position, seal by seal ring between the same pump housing of impeller, the pump cover, it is characterized in that: axle sleeve is equipped with in the lower end of axle, and axle sleeve cooperates with sliding bearing.
