Abstract
The utility model provides a high efficiency centrifugal pump structure, belongs to fluid machinery technical field. This pump includes the bearing pedestal structure of the seal structure and the drive end of the non - drive end of pump shaft. Seal structure adopts and sets up levogyration helixseal ring between the front shroud of impeller and the pump body, sets up the right -handed helix sealing ring between back shroud of impeller and the pump cover. The bearing pedestal structure includes that bearing pedestal one side sets up the bearing body, and back to back installation has two angular contact ball bearing in the bearing body, is used for axial positioning angular contact ball bearing's bolt fastening for the bearing cover on the bearing body. The sealing ring adopts the spiral sealing ring to the hand of spiral is relevant with the rotational speed of pump, and front shroud department sealing ring and the sealing ring spiral opposite direction of back shroud department have reduced and has let out leakage quantity, has improved the efficiency of pump. Having increased the axle at the deep groove ball bearing end and having used circlip, the angular contact ball bearing end uses the round nut to fix epaxial, and the impeller constitutes a whole, convenient to detach and adjustment axle clearance along with the axle with the bearing body.
Description
Technical field
This utility model relates to a kind of high efficiency centrifugal pump structure, belongs to fluid machinery technical field.
Background technology
Current existing centrifugal pump product impeller seals ring design is the most traditional, and gap is relatively big, and leakage rate is very big, the most inefficient, wastes electric energy；The maintenance of pump shaft, bearing removal is very inconvenient, the longest, less economical, cumbersome, and cannot accomplish that bearings at both ends disassembles simultaneously, and axially also cannot adjust gap.
Summary of the invention
For solving problems of the prior art, this utility model provides a kind of high efficiency centrifugal pump, it is therefore an objective to provide a kind of centrifugal pump key structure in hgher efficiency, more reasonable structure so that the overall performance of centrifugal pump has had further lifting.
The technical solution of the utility model is: a kind of high efficiency centrifugal pump structure, it includes pump shaft, the anti-drive end of pump shaft is provided with sealing structure, the drive end of described pump shaft is provided with bearing bracket structure, described sealing structure uses and arranges right hand helix sealing ring between front shroud of impeller and the pump housing, arranging left-turn spiral sealing ring between back shroud of impeller and pump cover, impeller is arranged on and stretches into the end of pump shaft in pump chamber；Described bearing bracket structure arranges bearing body in the side of bearing bracket, is provided with two angular contact ball bearings in bearing body back-to-back, and the bearing gland for axial orientation angle contact ball bearing is fixed by bolts on bearing body；The opposite side of bearing bracket arranges the deep groove ball bearing fixing with circlip.
The beneficial effects of the utility model are: this high efficiency centrifugal pump structure includes pump shaft, and the anti-drive end of pump shaft is provided with sealing structure, and drive end is provided with bearing bracket structure.Seal and between structure employing front shroud of impeller and the pump housing, right hand helix sealing ring is set, left-turn spiral sealing ring is set between back shroud of impeller and pump cover.Bearing bracket structure includes that bearing bracket side arranges bearing body, is provided with two angular contact ball bearings in bearing body back-to-back, and the bearing gland for axial orientation angle contact ball bearing is fixed by bolts on bearing body.Sealing ring uses spiral seal ring, and the hand of spiral is relevant with the rotating speed of pump, and at front shroud, sealing ring is contrary with the sealing ring hand of spiral at back shroud, decreases leakage rate, improves the efficiency of pump.Adding circlip for shaft at deep groove ball bearing end, angular contact ball bearing end uses round nut to be fixed on axle, and impeller constitutes an entirety with axle with bearing body, it is simple to dismantles and adjusts axial gap.

Detailed description of the invention
Fig. 1,2 structure charts showing a kind of high efficiency centrifugal pump.Centrifugal pump includes that pump shaft 7, the anti-drive end of pump shaft 7 are provided with sealing structure, and the drive end of pump shaft 7 is provided with bearing bracket structure.Sealing and arrange right hand helix sealing ring 2 between structure employing impeller 3 front shroud and the pump housing 1, arrange left-turn spiral sealing ring 4 between impeller 3 back shroud and pump cover 5, impeller 3 is arranged on pump shaft 7 end；Bearing bracket structure arranges bearing body 8 in bearing bracket 6 side, is provided with two angular contact ball bearings 12 in bearing body 8 back-to-back, and the bearing gland 10 for axial orientation angle contact ball bearing 12 is fixed by bolts on bearing body 8；Bearing bracket 6 opposite side is arranged with the fixing deep groove ball bearing 13 of circlip 9.
When using technique scheme work, a right hand helix sealing ring 2 it is provided with at front shroud of impeller, be provided with a left-turn spiral V-shaped ring 4 at back shroud of impeller, helicla flute be divided into single head with many first two, now in terms of drive end pump shaft for being rotated clockwise.Sealing ring uses spiral seal ring, sealing ring holding screw is fixed on impeller 3, rotate together with impeller 3, and the hand of spiral is relevant with the direction of rotation of pump, at front shroud, sealing ring is contrary with the sealing ring hand of spiral at back shroud, make pump greatly reducing the leakage rate at sealing ring in running, make the efficiency of pump be significantly improved；Simultaneously, owing to all there is pressure pump front and rear cover plate side, and spiral seal ring rotates with impeller and creates a power in opposite direction with cover plate lateral pressure, the power of both direction can make radial force increase in sealing ring length range, so sealing ring also can play the effect of hydrodynamic journal liquid polymers, with the gap of the pump housing 1, pump cover 5 reduce and the most easy to wear, extend the service life of pump.Arranging a bearing body 8 at bearing bracket 6, bearing body 8 fixes with bolt with bearing bracket 6, and they matched in clearance also use O RunddichtringO 11 to seal.Interior two angular contact ball bearings 12 of bearing body 8 are installed back-to-back, axially position with bearing gland 10；Bearing bracket 6 is fixed on axle built with deep groove ball bearing 13, bearing one end circlip for shaft 9, and bearing can together be removed with axle, and the frictional force between deep groove ball bearing 13 outer shroud and bearing bracket is less, and repair demolition is very convenient.Additionally angular contact ball bearing end uses round nut to be fixed on axle, impeller constitutes an entirety with axle with bearing body, as long as the position rotor parts adjusting bearing body are just followed and are moved together, fixing bearing body, bearing gland two groups of bolts can with the use of and reach to adjust the axial movement value of pump shaft rotor part.Reach to adjust impeller purpose of position in pump housing runner, reach optimal using effect.
