Abstract
The utility model discloses a formula that operates steadily multistage centrifugal pump, including pivot (1), mechanical seal subassembly (8), pump protecgulum (9), suction casing (10), pump middle section (12), discharge casing (14), bearing body, impeller (2), balance drum (3), snap ring (4) are equipped with in this pivot be equipped with location axle sleeve (5) in the pivot and in the side department of this snap ring, should fix a position the axle sleeve and pass through set screw (6) and fix in the pivot, should fix a position and be equipped with throttling bush (17) on the axle sleeve. 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 pump valve, is specifically related to a kind of centrifugal multistage pump multiple centrifugal pump.
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 formula that the operates steadily centrifugal multistage pump multiple centrifugal pump that rotor operation is stable can be made.
The purpose of this utility model realizes by following technical solution: the formula that operates steadily multistage from
Heart pump, including rotating shaft, mechanical sealing assembly, pump protecgulum, suction casing, pump stage casing, Spit Section,
Bearing body, equipped with impeller, balancing drum, snap ring in this rotating shaft, in described rotating shaft and
The side edge of this snap ring is equipped with positioning shaft sleeve, and this positioning shaft sleeve is fixed on rotating shaft by location screw
On, equipped with nockbush on this positioning shaft sleeve.
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 the nockbush of (throat) top of set directly weares and teares with axis friction.And make again from
Heart 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 the structural representation of steady formula rotor axial positioner of the present utility model.
Fig. 2 is that this utility model operates steadily the structural representation of formula centrifugal multistage pump multiple centrifugal pump.
Detailed description of the invention
Understanding with reference to Fig. 1, Fig. 2, this utility model operates steadily formula centrifugal multistage pump multiple centrifugal pump, including turning
Axle 1, mechanical sealing assembly 8, pump protecgulum 9, suction casing 10, pump stage casing 12, Spit Section 14,
Bearing body (containing left bearing body 18, right bearing body 19), and turnbuckle 13, tightening nut
16, equipped with impeller 2 (and stator 11, for multistage), balancing drum 3 (and balance in this rotating shaft 1
Set 15), snap ring 4 (point half formula), in described rotating shaft 1 and (right in the side edge of this snap ring 4
Side) equipped with positioning shaft sleeve 5, this positioning shaft sleeve 5 is fixed in rotating shaft 1 by location screw 6,
Equipped with nockbush 17 on this positioning shaft sleeve 5 (its throat).
Wherein, as it is shown in figure 1, described rotating shaft 1, impeller 2, balancing drum 3, snap ring 4, fixed
Position axle sleeve 5, location screw 6 constitute the steady formula rotor axial positioner of this centrifugal multistage pump multiple centrifugal pump
(can be collectively referred to as rotor part).Impeller 2, balancing drum 3 are successively set in rotating shaft 1 and use
Snap ring 4 is fixed, and the front portion of described positioning shaft sleeve 5 is arranged at the snap ring in the axial trough 7 of rotating shaft 1
On 4 and press fixing.
