[detailed description of the invention]
Refer to shown in Fig. 1 and Fig. 2, the invention discloses a kind of vapor core pump assembly whole dynamic balance test method, including
Following steps:
Step one, impeller shaft assembly dynamic balancing are installed
A. overlap 2 cylindricals groove vertically at dynamic balancing technics, it is ensured that rigging position is consistent every time, reduce due to assembly direction
The imbalance caused；And within dynamic balancing technics set 2 is equilibrated to 0.01g.cm, to reduce the imbalance of himself；
B. dynamic balancing technics set 2 and the impeller axle 1 cylindrical gap matched is not more than 0.005mm, and cylindrical groove alignment
Impeller shaft key groove；
C. balance ring 3 is close to when installing with locking plate along clockwise direction, consistent with retainer nut 4 tightening direction so that dress
Part status after joining is more consistent, reduces the imbalance caused due to keyway clearance；
D. the moment of 20.3N m is used to tighten retainer nut 4 by design drawing, it is ensured that to be rigid state during dynamic balancing.
Step 2, vapor core pump assembly whole dynamic balance are installed
A. by calculating, vapor core pump assembly is no more than the unbalancing value of 0.49g.cm and disclosure satisfy that properties of product need
Ask.In order to reduce assembly amount of unbalance, stability of enhancing product performance, consider the demand of economy, by vapor core pump assembly simultaneously
Unbalancing value is set to 0.2g.cm, is 4 times of impeller shaft assembly.
B. break general dynamic balancing machine to be typically only capable of rigid rotating class spare part is carried out dynamic balance method, design specialized
Fixture (is arranged on dynamic balancing machine, is fixed on special fixture by vapor core pump assembly, drives vapor core pump by motor belt
Impeller shaft assembly in assembly carries out dynamic balancing.General dynamic balancing machine is transformed, removes dynamic balancing machine and support the rolling on seat
Wheel and bearing, be arranged on special fixture dynamic balancing machine and support on seat, be arranged on special fixture by vapor core pump assembly, belt band
On impeller cylindrical in dynamic vapor core pump assembly, carry out dynamic balance running by driven by motor.
C. when unbalancing value is more than 0.2g.cm, can be at the impeller 6 of impeller shaft assembly 10 and balance ring 3 duplicate removal position
Remove material and ensure the second duplicate removal position 9 in requirement, specially impeller 6, and the first duplicate removal position 8 on balance ring 3.
D. in order to ensure that the poised state of vapor core pump assembly is constant after whole dynamic balance, in equilibrium process and after balance not
Allow dismounting impeller shaft assembly 10, the most detachably balance ring 3.
Wherein, vapor core pump assembly whole dynamic balance cleanliness control technology: owing to not permitting in equilibrium process and after balance
Being permitted dismounting assembly impeller shaft assembly, therefore, in equilibrium process, cleanliness control during duplicate removal is extremely important.According to dynamic balance running
Principle, product is protected when duplicate removal, and is used injector to remove iron filings by design specialized folder cleannes protecting tool set-up.
