Abstract
The utility model discloses a steady formula rotor axial positioning device of centrifugal pump, including pivot (1), balance drum (3), snap ring (4) be equipped with location axle sleeve (5) in the pivot and in the side department of this snap ring, should fix a position axle sleeve (5) and fix in pivot (1) through set screw (6). The utility model discloses a setting of location axle sleeve can prevent effectively that the snap ring breaks away from from the axial trough of pivot, improves the stability of rotor operation, can solve the direct problem with pivot friction and wear of the throttling bush of the throat top that is in the location axle sleeve again. And make compacter, the easy loading and unloading of structure setting of centrifugal pump again, improved work efficiency.
Description
Technical field
This utility model relates to a kind of centrifugal pump, and the rotor axial being specifically related to a kind of centrifugal pump is fixed
Position device.
Background technology
Rotor is the important critical component of centrifugal multistage pump multiple centrifugal pump (horizontal), the axial location of this rotor
Directly influence stability and the compactedness of structure design thereof of multistage centrifugal pump operation.At present,
Axially location basic employing screw-fixing type or snap ring gland for clearance fit type rotor are solid
Fixed pattern.Concentrate owing to screw-fixing type structure exists relative stress, be unfavorable for rotor operation
Stability.And snap ring gland is fixed need to be bolted on balancing drum with multiple, its structure and
Assemble the most relatively cumbersome.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and provide a kind of simple in construction,
The steady formula rotor axial positioner of the stable centrifugal pump of rotor operation can be made.
This utility model purpose realizes by following technical solution: the steady formula rotor of centrifugal pump
Axial direction positioning device, including rotating shaft, balancing drum, snap ring, in described rotating shaft and at this card
The side edge of ring is equipped with positioning shaft sleeve, and this positioning shaft sleeve is fixed in rotating shaft by location screw.
Use after this utility model structure, the setting of described positioning shaft sleeve can effectively prevent snap ring from
The axial trough of rotating shaft detaches, improves the stability of rotor operation, also solve the problem that and be in locating shaft
The problem that nockbush above the throat of set directly weares and teares with axis friction.And make again centrifugal pump
Structure arrange more compact, be prone to handling, improve work efficiency.
Accompanying drawing explanation
With embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Understand with reference to Fig. 1, the steady formula rotor axial positioner of this utility model centrifugal pump
(can be collectively referred to as rotor part), including rotating shaft 1, balancing drum 3, snap ring 4 (point half formula),
Equipped with positioning shaft sleeve 5 in described rotating shaft 1 and in the side edge (right edge) of this snap ring 4,
This positioning shaft sleeve 5 is fixed in rotating shaft 1 by location screw 6.
Wherein, equipped with impeller 2 (multistage) in described rotating shaft 1.Its impeller 2, balancing drum 3
Being successively set in rotating shaft 1 and fix with snap ring 4, the front portion of described positioning shaft sleeve 5 is arranged at
On snap ring 4 in the axial trough 7 of rotating shaft 1 and press fixing.
Claims (2)
1. the steady formula rotor axial positioner of centrifugal pump, including rotating shaft (1), balancing drum
(3), snap ring (4), it is characterised in that: in described rotating shaft (1) and in this snap ring (4)
Side edge equipped with positioning shaft sleeve (5), this positioning shaft sleeve (5) is solid by location screw (6)
It is scheduled in rotating shaft (1).
The steady formula rotor axial positioner of centrifugal pump the most according to claim 1,
It is characterized in that: the front portion of described positioning shaft sleeve (5) is arranged at the axial trough (7) of rotating shaft (1)
In snap ring (4) on and press fixing.
