Abstract
The invention discloses the centering method of rotor assembly during a kind of assembling of multistage pump, the axle for installing suction side axle sleeve and key is pierced into suction casing；First order impeller and impeller interstage sleeve are put into, and impeller is abutted front shaft sleeve, pump shaft is then moved, makes first order impeller outlet center consistent with first order guide vane import center；On stage casing after layer overlay fish paper pad, stage casing and second level impeller are loaded onto, then, loads onto impeller interstage sleeve, stage casing, third level impeller successively, so that pump case, loads onto pump housing bolt and nut, nut is tightened；Load onto balancing frame, balancing frame is locked with axle sleeve and axle sleeve locking nut, balancing frame is close to balance ring, checks the mark of pump shaft front end, make its equal because impeller spacing has been measured and adjusted before assembly with stator spacing, thus impeller at different levels respectively with all centerings of corresponding stator.Centering can be realized exactly by this method, ensure the security that multistage pump uses.
Description
Technical field
The present invention relates to a kind of method, the centering method of rotor assembly when being assembled more particularly, to a kind of multistage pump.
Background technology
Machinery refers to the general name of machine and mechanism.Machinery is exactly that people can be helped to reduce work difficulty or labour-saving instrument dress
Put, as a kind of article of chopsticks, broom and tweezers can be said to machinery, they are simple and mechanical.And complicated machinery is just
It is to be made up of the simple and mechanical of two or more.These more complicated machineries are generally called machine.From structure and fortune
From the viewpoint of dynamic, mechanism and machine and indistinction, machinery is loosely referred to as.Generally speaking, machinery is exactly that people can be helped to reduce work
Difficulty or labour-saving tool device, as a kind of article of chopsticks, broom and tweezers can be said to machinery, they are simple
Machinery.And complicated machinery is exactly to be made up of the simple and mechanical of two or more.Generally these more complicated machineries
Make machine.Mechanical engineering is exactly using relevant natural science and technological sciences as theoretical foundation, is incorporated in production practices and accumulates
Technical experience, research and solve exploitation design, manufacture, installation, utilization and repair it is various machinery in theory and actually ask
One application branch of learning of topic.The development of each engineering field requires that mechanical engineering has development adaptable therewith, is required for machine
Machinery necessary to tool engineering provides.Some mechanical inventions and perfect, new engineering technology and new industry can be caused again
Occur and develop.Such as the manufacture success of large-sized power machinery, facilitate the foundation of power system；The invention of locomotive result in iron
The rise of road engineering and railway cause；The invention and progress of internal combustion engine, gas turbine, rocket engine etc., and aircraft and boat
Its device succeeds in developing the rise that result in Aeronautics and Astronautics cause；The development of high-tension apparatus result in many new synthesis chemistry
Success of engineering etc..Mechanical engineering is exactly that the motive force of development is obtained under the pressure of the demand improved constantly in every respect, while again
The ability improved and innovated from the progress of every subjects and technology.
When multistage pump assembles, it is impossible to realize the centering of rotor assembly exactly, cause multistage pump to exist when in use very
Big risk.
The content of the invention
It is above-mentioned existing when multistage pump assembles it is an object of the invention to overcome, it is impossible to realize pair of rotor assembly exactly
In, cause multistage pump the problem of very big risk to be when in use present, pair of rotor assembly when devising a kind of multistage pump assembling
Middle method, centering can be realized exactly by this method, ensure the security that multistage pump uses.
The purpose of the present invention is achieved through the following technical solutions：The centering method of rotor assembly when multistage pump assembles, including
Following steps：
（1）The axle for installing suction side axle sleeve and key is pierced into suction casing；
（2）First order impeller and impeller interstage sleeve are put into, and impeller is abutted front shaft sleeve, pump shaft is then moved, makes first order impeller
Export center is consistent with first order guide vane import center, now makees a note on axle of the pump shaft front end with respect to gland end face
Number, it is easy to the last centering situation for checking impeller and guide vane, when adjustment first order impeller outlet center is with guide vane centering, impeller should
Against front shaft sleeve, now impeller can not be close to suction casing；
（3）On stage casing after layer overlay fish paper pad, load onto stage casing and second level impeller, then, load onto successively impeller interstage sleeve,
Stage casing, third level impeller, so that pump case, loads onto pump housing bolt and nut, nut is tightened；
（4）Balancing frame is loaded onto, is locked balancing frame with axle sleeve and axle sleeve locking nut, balancing frame is close to balance ring, checks pump
The mark of axle front end, if mark position does not become, illustrate first order impeller outlet center and the center centering of first order vane inlet
, make its equal because impeller spacing has been measured and adjusted before assembly with stator spacing, thus impeller at different levels respectively with it is corresponding
Stator all centerings.
In summary, the beneficial effects of the invention are as follows：Centering can be realized exactly by this method, ensure that multistage pump makes
Security.
Embodiment
With reference to embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited only to
This.
Embodiment：
The centering method of rotor assembly, comprises the following steps when multistage pump assembles：
（1）The axle for installing suction side axle sleeve and key is pierced into suction casing；
（2）First order impeller and impeller interstage sleeve are put into, and impeller is abutted front shaft sleeve, pump shaft is then moved, makes first order impeller
Export center is consistent with first order guide vane import center, now makees a note on axle of the pump shaft front end with respect to gland end face
Number, it is easy to the last centering situation for checking impeller and guide vane, when adjustment first order impeller outlet center is with guide vane centering, impeller should
Against front shaft sleeve, now impeller can not be close to suction casing；
（3）On stage casing after layer overlay fish paper pad, load onto stage casing and second level impeller, then, load onto successively impeller interstage sleeve,
Stage casing, third level impeller, so that pump case, loads onto pump housing bolt and nut, nut is tightened；
（4）Balancing frame is loaded onto, is locked balancing frame with axle sleeve and axle sleeve locking nut, balancing frame is close to balance ring, checks pump
The mark of axle front end, if mark position does not become, illustrate first order impeller outlet center and the center centering of first order vane inlet
, make its equal because impeller spacing has been measured and adjusted before assembly with stator spacing, thus impeller at different levels respectively with it is corresponding
Stator all centerings.
Centering can be realized exactly by this method, ensure the security that multistage pump uses.
