Critical component is easy to be damaged, and increases experimentation cost；6, there are biggish security risk, runner assembly has during the test
It may topple over.
Summary of the invention
It is an object of the present invention to provide the movable propeller turbine runner static balance test devices based on three fulcrum weight methods
And method, this device and method replace traditional steel ball runner plate method, are used for movable propeller turbine runner static balance, Jin Erti
High test efficiency precision, reduces test security risk, solidity test device reduces experimental rig cost, turns for power station unit
Wheel static balancing test provides safeguard.
In order to realize above-mentioned technical characteristic, the object of the present invention is achieved like this: the axis based on three fulcrum weight methods
Circulate propeller type water turbine static balance of rotary wheel experimental rig, it includes the balancing frame for being used to support web, the bottom of the balancing frame
Portion is equipped with multiple pressure sensors, is in contact at the top of the bottom of the pressure sensor and balance base；The web
On blade is installed, connector is installed at the top of web.
The bottom outer-edge of the web is provided with multiple synchronous jacking devices.
There are three the pressure sensor is total, and it is evenly arranged on the bottom of balancing frame.
The levelness of the balance base is less than 0.02mm/m.
The examination of movable propeller turbine runner static balance test device based on three fulcrum weight methods described in any one
Proved recipe method, it the following steps are included:
Step1: just balance；The first balance assembly formed for web and connector carries out static balancing test, in turn
Check the residual unbalance, and residual unbalance, orientation of just balance assembly；
Step2: blade apolegamy；For the purpose of weight mass minimum when overall balance, according to the injustice of first balance assembly
Measurement and eccentric orientation, comprehensively consider the mass deviation of each blade, determine the optimal installation site of each blade；
Step3: overall balance；The static balance examination carried out for the overall balance assembly that web, connector and blade are formed
It tests, so that residual unbalance, is met the requirement of allowable amount of unbalance by counterweight.
