Damping time |
Damping time:8±4s |
1.Test machine:test special tools 2.method:T=3.5N・m(35kgf・cm) make the counterpoise position at 0゚,the reset.(once is ok) a.pull the counterpoise to110゚position,then to 90゚~80゚(85゚is best),measure the working angle from 70 to 0 degree b.load torque in horizontal line:3.5N・m(35kgf・cm) c.test angle:70゚→ 0゚ d.test temperarure:23℃±2℃ |
2.2 |
durability |
1)working angle more than 2 seconds 2)no oil leakage, no broken |
1)durability test condition a.test machine:test special tools(drop free) b.test method:force close open angle to close angle 100゚±10゚。 c.force close:pneumatic pressure 30~50PSI d.working angle:0゚←→110゚ e.frequency 10 time/minutes f.test temperature:23℃±2℃ g.durability time:50,000cycles 2)judging criteria after test a)working angle:after test, put damper at room temperature 23℃±2℃ more than 24 hours,test it according to item 2.1 and get the damping time |
