Think that running status is that the quality of counterweight is exactly equal to the quality plus load in sedan-chair for the car deadweight.But fixing counterweight can not be put down
Weighing apparatus load therefore can only select a suitable coefficient of balance by unloaded to the change being fully loaded with, and the state that elevator is run multiple times is from total
Closest to preferable poised state on body.
Test method specified in test elevator surveillance inspection procedure has：Current measurement is passed through for ac motor and ties
Sum velocity measures, and does current load curve or the speed curve of load, determines coefficient of balance with upper and lower operation curve intersection point.For
Dc motor passes through current measurement and combines voltage measurement, does current load curve or the voltage curve of load, determines balance system
Number.At present elevator install in supervision and inspection using most be to do current load curve to determine coefficient of balance.The method requires
Car carries 0,25%, 50%, 75%, 100% rated load respectively, carries out running along whole straight.Respectively on record car
Come downwards to current value during same level, then do current load curve and determine coefficient of balance.
The method has the following disadvantages：The consuming time is long, and an elevator photo-equilibrium ratio test will 1～2h；Work is strong
Degree is big, repeatedly will move counterweight in test；Error component is many, because when doing current load curve, the measured value of electric current is many,
Each measured value can have error；Also error is had during the coordinate that measurement point is determined on chart；In addition described point, make during curve by
Different with smooth degree in the line style retouched, will also result in error；Curve chart drafting is complicated, time-consuming, and protocol requires in inspection
Scene completes, and such a whole morning at most can only check one, and this is inharmonic with the rapid growth of elevator quantity.
