Abstract
A kind of vertical emergency drainage centrifugal pump of the utility model, has carried out structure innovation on the basis of traditional vertical emergency drainage centrifugal pump.By forming pressure releasing chamber by throw rijng, water outlet volute, centrifugal impeller, grease chamber lower cover, grease chamber in centrifugal impeller upper design, and the position in pressure release water hole is lower than throw rijng, guarantees the good running environment of double mechanical seal；And several flushing holes are designed on water inlet front cover, avoid the siltation of centrifugal impeller import silt.
Description
Technical field
The utility model belongs to machinery field, specially a kind of vertical emergency drainage centrifugal pump.
Background technique
Vertical emergency drainage centrifugal pump is widely used in Urban Waterlogging, the emergency drainages such as mine is speedily carried out rescue work, frequently with electromechanics one
The submersible pump structure of body has the characteristics that installation is simple, easy to operate.Traditional emergency drainage centrifugal pump is in use, double
End surface mechanical sealing is in higher-pressure region, and since medium includes mud containing sand, sewage impurity is easily accessible double mechanical seal, so that
The indoor mechanical seal of oil is easy to happen the failure for damaging and leading to whole pump.If containing higher concentration in the medium pumped simultaneously
Sewage when, due to pumping or stopping or opening, in the siltation easy to form of the impeller inlet of pump, cause impeller water inlet unsmooth or even completely stifled
Plug, the reliability of pump be not high.To improve vertical emergency drainage centrifugal pump stability and reliability, in the present invention, utilize
The pressure at mechanical seal is effectively reduced in pressure release water hole, and improves the running environment of mechanical seal using throw rijng；Impeller into
The mouth of a river cooperates flushing hole, carries out automatic erosion and deposition.
Utility model content
The utility model is intended to provide a kind of vertical emergency drainage centrifugal pump, enterprising in traditional vertical emergency drainage centrifugal pump
Row structure innovation, simplification.In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of vertical emergency drainage centrifugal pump, by cable, submersible motor, upper bearing (metal), lower bearing, grease chamber, Double End
The structure compositions such as mechanical seal, centrifugal impeller, water inlet front cover, water outlet volute, upper choma, lower choma, water inlet pedestal.
The centrifugal impeller cooperates with upper choma, lower choma respectively, and collects high-pressure fluid by water outlet volute, the row of completion
Water.
Centrifugal impeller upper design throw rijng is discharged on volute and devises pressure release water hole, and pressure release water hole is lower than
Throw rijng, double mechanical seal are in grease chamber, and double mechanical seal is in throw rijng top.Theoretically no matter water dumping
Ring or mechanical seal are in low pressure, run in clean environment.
The centrifugal impeller lower part design has into water front cover, and design has flushing hole on front cover of intaking, and utilizes the height inside pump
Water slug impeller intake region is pressed, automatic erosion and deposition is realized, avoids silt hardened.
The utility model optimizes vertical emergency drainage centrifugal pump structure, improves pump mechanical sealing running environment,
And the hardened problem of impeller inlet is resolved, the reliability and service life of elevator pump.
Detailed description of the invention
The present invention will be further described with embodiment with reference to the accompanying drawing.

A kind of vertical emergency drainage centrifugal pump main sectional view that Fig. 2 designs for the utility model.In figure: on 1. cables 2.
Choma on 7. throw rijng of bearing 3. submersible motor, 4. lower bearing, 5. grease chamber, 6. double mechanical seal, 8. pressure release water hole 9.
10. the lower choma 12. of centrifugal impeller 11. is intake, water inlet 14. flushing hole 15. of pedestal of front cover 13. is discharged 16. pressure releasing chamber of volute
17. grease chamber lower cover.
Specific embodiment
Centrifugal impeller 10 is assemblied in water outlet volute 15, and 10 top of centrifugal impeller and upper choma 9 cooperate, under centrifugal impeller 10
Portion and lower choma 11 cooperate；Pressure release water hole 8 is set on water outlet volute 15, is discharged volute 15, centrifugal impeller 10, grease chamber lower cover
17, grease chamber 5 surrounds to form pressure releasing chamber 16, and throw rijng 7 is installed between centrifugal impeller 10 and grease chamber lower cover 17, and is located at pressure releasing chamber
Within 16, the position in pressure release water hole 8 is lower than throw rijng 7, is acted on by 8 quick pressure releasing of pressure release water hole, 16 inside of pressure releasing chamber and ring
Border pressure is close and water level inside is lower than throw rijng 7, ensure that cleaning and the environment under low pressure of double mechanical seal 6, Double End
The service life of mechanical seal 6 is improved with reliability.
Several flushing holes 14 are designed on water inlet front cover 12, and when pump operation, high pressure water is sprayed from flushing hole, to water inlet bottom
Region between seat 13 and centrifugal impeller 10 is rinsed, and avoids the siltation of granule foreign.
A kind of vertical emergency drainage centrifugal pump of the utility model, structure is simple, compact, so that vertical emergency drainage is centrifuged
The reliability of pump is improved.
