Background technique
Shaft coupling is also known as shaft coupling, for by different institutions driving shaft and driven shaft link up revolve together securely
Turn, and the mechanical part of passing movement and torque.It is often semi-synthetic by two, respectively with the connection such as key or tight fit, it is fastened on two axis
End, then linked up two halves by certain mode.Shaft coupling can have concurrently between small electromotor axis and pump shaft since manufacture is installed
Inaccurately, the offset (including axial dipole field, radial deflection, angular variation) that deformation and the reasons such as thermal expansion when working are occurred with
And mitigate impact, absorbing.The rotation center of two axis that the shaft coupling of pump and motor is connected should be stringent concentric, shaft coupling
It during installation must accurate centering, centering.Otherwise it will cause very big stress on shaft coupling, and will severely impact
Normal work of other components on axis, bearing and axis, or even the vibration or the damage that cause whole equipment and basis etc..
Nuclear power station first stage of the project 2 units in field gulf are configured with more than 200 platform horizontal small centrifugal pumps altogether, in order to guarantee that rotation is set
Standby operational reliability, provides according to maintenance procedure, and rotating machinery is both needed to carry out in shaft coupling pair in its disassembling overhaul.Power plant
Horizontal small centrifugal pump couplings are made of pump side clutch, motor side clutch and shaft coupling, wherein horizontal small centrifugal pump
Model it is different, the diameter and length of shaft coupling be not also identical.
The magnetic stand used when previous horizontal small centrifugal pump couplings centering contacts loosely with backrest wheel shaft arc surface
It leans on, easily causes indicator shaking, cause the untrue of data；The model of horizontal small centrifugal pump is different, and the diameter of shaft coupling is big
Small and length is not also identical, and the shaft coupling centering for different model need to match different alignment tools, and be both needed to self manufacture,
The alignment tool of selection needed for the personnel of needing repairing are clear from the horizontal small centrifugal pump for different model causes to overhaul
Journey is low.
The general centralising device of horizontal small centrifugal pump of the invention is simple and reliable for structure, easy to operate；The horizontal small
The centralising device of centrifugal pump is fixed by fixture and shaft coupling axis, it is possible to prevente effectively from since the shaking of percentage list index causes
The untrue property of data；The centralising device of the horizontal small centrifugal pump is by adjusting the length of connecting rod and the guide groove of fixed plate
Position is fixed to be adapted to the shaft coupling of different model, meets the centering problem of power plant's different model horizontal small centrifugal pump.
Summary of the invention
Present invention solves the technical problem that:
The present invention provides a kind of general centralising device of horizontal small centrifugal pump, and structure is simple, easy to use, meets power plant
The small sleeping pump centering problem of different model.
The technical solution adopted by the present invention:
A kind of general centralising device of horizontal small centrifugal pump, including dial gauge, fixed plate one, dial framework, connecting rod one, company
Extension bar two, fixed plate two, fixture, double threaded screw, motor side clutch, jackscrew, shaft coupling, pump side clutch.
The pump side clutch is mounted on the left side of shaft coupling；Motor side clutch is mounted on the right side of shaft coupling.
The fixture is fixedly mounted on shaft coupling by double threaded screw, and is located at the right side of motor side clutch.
The fixed plate two at the top of screw and fixture by being fixedly connected；Fixed plate one connects by the way that screw and dial framework are fixed
It connects.
The fixed plate two is fixedly connected with connecting rod two；Fixed plate one is fixedly connected with connecting rod one.
The connecting rod one is inserted into connecting rod two, and by jackscrew in place by connecting rod one and connecting rod two
It is fixed.
