Abstract
The invention relates to a novel multilevel horizontal centrifugal pump which comprises a pump body, a thrust device, and a transition sleeve which is arranged between the pump body and the thrust device, wherein the thrust device comprises a thrust shaft and a plurality of bearings used for supporting the thrust shaft, a water outlet is formed in the output end of the pump body. The centrifugal pump is characterized in that a water filling port is formed near the position on the pump body and in which the transition sleeve is connected with the pump body. By adopting the technical scheme, the water filling port is formed in the pump body, compared with existing structure, for the novel multilevel horizontal centrifugal pump, on one hand, when the novel multilevel horizontal centrifugal pump is subjected to maintenance and service, only the connection of the transition sleeve and the pump body needs to be dismantled, so that the workload is reduced, the operation is convenient, and the maintenance time is shortened, in addition, as the water filling port does not need to be formed in the transition sleeve, the volume and the weight can be greatly reduced, so that the manufacturing cost is reduced and the manpower is saved; and on the other hand, as the axial size of the transition sleeve is reduced, the length of the thrust shaft is shortened, so that the deflection generated by overlong length of the shaft is reduced, further, the vibration of a unit is reduced and the service life of the unit is prolonged.
Description
Technical field
The present invention relates to the centrifugal pump technical field, the horizontal centrifugal pump of particularly a kind of new multistage.
Background technique
In oil field operation, multistage horizontal centrifugal pump is used in the produced-water reinjection system, and its water filling hole is connected with the produced-water reinjection pipeline, and water outlet is drained into sewage in the water injection well.At present, Chang Yong multistage horizontal centrifugal pump by the pump housing, be located at transmission shaft and impeller, the thrust device in the pump housing and be connected thrust device and the spacer shell of the pump housing constitutes.Wherein thrust device by thrust shaft, support thrust shaft a plurality of bearings, bearing outside, be located at the end block piece at bearing outside two ends, the mechanical seal that is located at respectively between two ends end block piece and the thrust shaft constitutes.On spacer shell, be provided with water filling hole, be provided with mechanical seal between spacer shell and the thrust shaft, be provided with water outlet at the output terminal of the pump housing.Multistage horizontal centrifugal pump is when work, and a plurality of bearings on the thrust device bear the end thrust that is formed by impeller two ends height pressure reduction, so temperature rise is very fast, and care and maintenance need be often carried out in easily loss, and above-mentioned in addition each mechanical seal also is easy damage structure.When above-mentioned multistage horizontal centrifugal pump is carried out care and maintenance, need to remove being connected of water filling hole and produced-water reinjection pipeline and being connected of spacer shell and the pump housing, so dismounting bothers, wastes time and energy.In addition, said structure also exists thrust shaft longer, and axial force is excessive, easily produces and scratches change, thereby cause unit to produce vibration, has reduced the deficiency in the working life of unit.
Summary of the invention
The present invention is convenient to care and maintenance for the technical problem that exists in the solution known technology provides a kind of, saves manpower, is reduced unit vibration, improves the unit horizontal centrifugal pump of new multistage in working life.
The technological scheme that the present invention takes for the technical problem that exists in the solution known technology is:
The horizontal centrifugal pump of a kind of new multistage comprises the pump housing, thrust device, is located at the spacer shell between the pump housing and the thrust device; Described thrust device comprises thrust shaft and supports a plurality of bearings of thrust shaft; The output terminal of the described pump housing is provided with water outlet, it is characterized in that: be provided with water filling hole near the position that is connected with spacer shell on the described pump housing.
The present invention can also adopt following technical measures:
Described bearing is four, and is angular contact ball bearing; Four per two of bearings are one group, between two groups spacer sleeve are set, and wherein arrange according to back-to-back mode away from one group of bearing of the pump housing, and another group bearing is arranged according to serial fashion.
Advantage and good effect that the present invention has are:
The present invention adopts technique scheme, water filling hole is arranged on the pump housing, and it is than existing structure, on the one hand when carrying out care and maintenance, only needing to remove spacer shell got final product with being connected of the pump housing, thereby reduced workload, made things convenient for operation, shortened engineering time, in addition, owing to water filling hole need be set on spacer shell, its volume and weight can reduce significantly, thereby has also reduced manufacture cost and saved manpower; On the other hand,, cause the thrust shaft shorten length, thereby reduced the change of scratching that produces owing to axial length is long, and then reduced the vibration of unit and prolonged working life of unit because the spacer shell axial dimension is less.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, the pump housing; 1-1, water filling hole; 1-2, water outlet; 2, thrust device; 2-1, thrust shaft; 2-2, bearing; 2-3, spacer sleeve; 3, spacer shell.
Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the horizontal centrifugal pump of a kind of new multistage comprises the pump housing 1, thrust device 2, is located at the spacer shell 3 between the pump housing and the thrust device.Described thrust device comprises thrust shaft 2-1 and supports a plurality of bearing 2-2 of thrust shaft.Other formations of thrust device and annexation are with reference to prior art.The output terminal of the described pump housing is provided with water outlet 1-2.Be provided with water filling hole 1-1 near the position that is connected with spacer shell on the described pump housing.Promptly on the pump housing, the suction casing that radially extends along the pump housing is set, forms water filling hole near the position that is connected end face with transitioning end.Adopt said structure, thrust device and spacer shell form an independently carrier, and the water filling hole and the pump housing become one structure, when care and maintenance is carried out in bearing and mechanical seal, only need to remove being connected of spacer shell and the pump housing, and do not need to remove being connected of water filling hole and produced-water reinjection pipeline.
In the said structure, the arrangement mode of a plurality of bearings is preferably as follows structure: described bearing is four, and is angular contact ball bearing.Four per two of bearings are one group, and spacer sleeve 2-3 is set between two groups.Wherein arrange according to back-to-back mode away from one group of bearing of the pump housing, another group bearing is arranged according to serial fashion.A plurality of bearings adopt above-mentioned distribution mode, under the situation that guarantees bearing capacity, have improved the non-deformability of bearing, thereby prolonged the fatigue limit of bearing, therefore, can reduce its care and maintenance number of times, thereby reduce maintenance cost and improved the effective operation of apparatus rate.
