Products Advantages:
1. Abundant the introduction of Japanese production equipment and advanced technology.
2. Daming oil is silicone oil which damping function is stable when the machine temperture reach from above 80 degree.to below 20degree. And we buy the silicone oil from Japan.
3. Our damper life time can be used 50,000 time.
4. The damper had approved the ISO9001:2008and RoHS certification.
5. 100% products tested before delivery it.
6. Free sample can be send to you for test at first.
1.General
This specification give the related model damper technical requirement, testmethod and product model description, apply to damper production and test.
2.Test requirement and test method
| item | desctiption | Technical requirment | Test method |
2.1 |
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,the reset.(once is ok)a.pull the counterpoise to110position,then to 90~80(85is 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→ 0 d.test temperarure:23ºC±2ºC |
| 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±10. c.force close:pneumatic pressure 30~50PSI d.working angle:0←→110 e.frequency 10 time/minutes f.test temperature:23ºC±2ºC g.durability time:50,000cycles 2)judging criteria after test a)working angle:after test, put damper at room temperature 23ºC±2ºC more than 24 hours,test it according to item 2.1 and get the damping time b)appearance:judge the appearance |
| 2.3 | Working temperature range | 1)-5ºC:10 ± 5s 2)50ºC:6 ± 3s |
1)working temperature test condition a.damper place temperature:-5ºC,50ºC b.damper place time:>3 hours 2)judging criteria after test place the damper in each temperature, and then put in room temperature, test it according to item 2.1 |
| 2.4 | Storage temperature | 1)damping time change rate in preliminary stage within±30% 2)no oil leakage, no broken |
1)storage temperature test condition a.damper storage temperature:-20ºC,60ºC b.damper storage time:72hours 2)judging criteria after test a.damping time, place the damper in each temperature and then put in room temperature, test the damping time according to item 2.1 b.Appearance: judge the damper appearance. |
| 2.5 | Reverse torque | <1.0N-m(10kgf-cm) | 1)rotate speed:1rpm 2)test angle:110° 3)method:make the damper rotor rotate to oppsitive direction. Test its torque. |
| 2.6 | Maximum working angle | 110° | Guarantee item 2.2 durability working angle range |
| 2.7 | size | See drawing | |
| 2.8 | weight | 25g±1g | |
| 2.9 | rotation | White cover left, black cover right |
Soft-close:
Just one fingertip touch, the lid close all by itself. Gently and silently, like the snow falling down in Christmas Eve.
Quick-release:
Click the button, lift off the lid, just two movements without using any tools put an end to annoying disassemble procedure.
Easy Clean:
Release the seat & cover, clean the hinges and pan with warm water and a mild detergent. Afterwards rub dry. Dont use any caustic or scouring agents. This design is for highest hygienic safety.
