Abstract
The utility model discloses a kind of radial direction subdivision high pressure multiple-stage centrifugal pump, its architectural feature is that a guide bearing is set at the intergrade impeller of pump；Flexible member is provided between thrust axis socket end the inner and bearing body.Due to setting up a guide bearing at the intergrade impeller of pump, the guide bearing is supported to pump shaft and rotor part, so as to enhance the rigidity of pump shaft, strengthens the stability of rotor part, extends the service life of equipment；The setting of the inner flexible member and between bearing body of thrust bearing, when pump is not actuated, in the presence of flexible member, dynamic and static balancing frame is in released state, after pump startup, under the synergy of axial force and equilibrant force, dynamic and static balancing frame keeps rational axial gap, can automatically balancing axial force can guarantee that dynamic and static balancing frame does not rub again, extend bascule service life.
Description
First, technical field
The utility model is related to mechanical engineering pump class technical field, specifically a kind of radial direction subdivision high-pressure multi-stage centrifugation
Pump.
2nd, background technology
The series of the radial direction subdivision high pressure multiple-stage centrifugal pump of current application is general no more than 12 grades.Trace it to its cause is to exceed
12 grades of radial direction subdivision high pressure multiple-stage centrifugal pump is long due to pump shaft, using when its pump shaft bending it is more serious, between each part
It is easy to wear, big, efficiency is vibrated during operation low.Next to that axial force is big, cause bascule service life short.
3rd, the content of the invention
In order to overcome the shortcomings of above-mentioned technology, the purpose of this utility model provides a kind of guarantee pump shaft rigidity, extension balance
The radial direction subdivision high pressure multiple-stage centrifugal pump of device service life.
In order to realize the purpose of this utility model, the technical scheme that the utility model is used is：The radial direction subdivision high pressure
Centrifugal multistage pump multiple centrifugal pump is mainly made up of pump shaft, impeller, suction casing, interlude, Spit Section and bearing body；Static balancing disk is located at Spit Section
Center, dynamic balancing disk corresponding with static balancing disk is connected with pump shaft；Thrust bearing is located in bearing body；It is characterized in that
The individual guide bearing for strengthening to rotor part support is set at the intergrade impeller of pump；In thrust axis socket end the inner and bearing body
Between be provided with can be according to the size of axial force come the flexible member of balancing control start and stop.
The beneficial effects of the utility model are：Due to setting up a guide bearing, the guide bearing pair at the intergrade impeller of pump
Pump shaft and rotor part are supported, so as to enhance the rigidity of pump shaft, pump shaft will not flexural deformation, enhancing rotor part it is steady
It is qualitative, extend the service life of equipment；The setting of thrust bearing the inner flexible member, when pump is not actuated, in flexible member
In the presence of, dynamic and static balancing frame is in released state；It is dynamic and static under the synergy of axial force and equilibrant force after pump startup
Balancing frame keeps rational axial gap, can automatically balancing axial force can guarantee that dynamic and static balancing frame does not rub again, extension
Bascule service life.
4th, illustrate
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the cross section structure diagram of the utility model radial direction subdivision high pressure multiple-stage centrifugal pump.
In figure, 1. intergrade impeller, 2. guide bearing, 3. static balancing disk, 4. dynamic balancing disk, 5. flexible member, 6. thrust
Bearing.
5th, specific embodiment
In the accompanying drawings, the utility model radial direction subdivision high pressure multiple-stage centrifugal pump is main by pump shaft, impeller, suction casing, centre
Section, Spit Section and bearing body are constituted；Static balancing disk 3 is located at the center of Spit Section, dynamic balancing disk 4 corresponding with static balancing disk 3
It is connected with pump shaft；Thrust bearing 6 is located in bearing body；When the series of pump is more than 12 grades, in (the leaf of intergrade impeller 1 of pump
Wheel number is odd number) place sets a guide bearing 2, if impeller number is even number, two guide bearings is set at middle both stage impellers
2, guide bearing 2 is used for strengthening the support to rotor part；Flexible member 5, bullet are provided between the end of thrust bearing 6 the inner and bearing body
Property element 5 can be according to the size of axial force come the start and stop of balancing control.
