Description
Technical field
The present invention relates to the centering of the widely used 100AY120 types centrifugal pump couplings of petroleum chemical enterprise, its centering is looked for
Positive fixture can measure radial and axial displacement simultaneously, fast and accurate can especially realize the centering process of motor shaft and pump shaft.
Background technology
At present, in petroleum chemical enterprise there be the conventional shaft coupling centering method of slewing：Ruler and clearance gauge carry out shaft coupling
Device centering method, single table method, double meter method, genuine standard and laser alignment method for centering.Shaft coupling is carried out using ruler and clearance gauge
During centering, the radial missing in the cylindrical each orientation of shaft coupling is measured with angle square and clearance gauge, two half a couplers are measured with clearance gauge
Axial gap deviation between end face, by analyzing and adjusting, reaches two shaft assignments.This method is simple to operate, but precision is not high,
The error of centralization is larger, is only applicable to that equipment rotating speed is relatively low, the less demanding occasion of centering；Single table method is recent domestic application
A kind of increasingly extensive shaft coupling centering method, this method only determines the cylindrical radial direction reading of shaft coupling wheel hub, accident
The axial reading of end face is measured, only with one piece of dial gauge during measurement operation, radially or axially deviation can only be measured, and can not realize
Effective positioning of dial gauge or amesdial, causes measuring result error big, accuracy of alignment is not high；The laser alignment risen in recent years
Instrument centering is that, by laser transmitter projects laser beam, laser beam reaches receiver and received and true by photoelectrical position sensor
Determine initial position.When rotating rotary shaft, any misalign can all cause laser beam to deviate initial position.Computer utilizes laser
Beam the variable quantity of position and calculates equipment centering situation from shaft coupling center to the distance of receiver on a sensor.Equipment pair
Middle situation can also can both be expressed at shaft coupling at equipment lower margin.But the centering of general slewing does not have
Be necessary to use laser alignment instrument because instrument is very accurate and expensive in itself, therefore laser alignment instrument be only used for it is large-scale
The centering of Key generating unit.It is general using the centering for the small rotary device coupling having a large capacity and a wide range in current industrial enterprise
All over use double meter method or genuine standard, because device structure varies, measuring instrumentss it is relatively difficult when being mounted with, even
It can not install, even if being fixed using magnetic stand, but due to its rigidity not enough, amount of deflection can be produced, and then it is larger to produce measurement
Error, has a strong impact on its measurement accuracy.
