Equipment: Elevator button lifetime testing machine
Button Lifetime (million times): T/CEA 0012—2020 >3, Koyo elevator >6
Test conditions: The test is performed at room temperature, and the button is mounted on a fixed platform. Turn on the machine, and the button is lit.
Frequency: Not less than 1Hz; pressure: not less than 10N.
Criteria: Normal function, good electrical performance; The failure rate is not more than 2 parts per million.
Equipment: Escalator steps (pedal) roller reliability test bench
Roller lifetime: TSG T 7007-2016: the main roller loading pressure and test run time is at least 1300N, 250h
Test conditions: The test is carried out at room temperature, and should be tested on a special roller fatigue testing machine. The roller should be installed on a fixed platform, and the roller should be tightly and evenly installed. Rotation is Smooth.
Test method: For each type of roller specification， four rollers as one set. it is appropriate to increase the number of experimental groups; The loading pressure should be set corresponding to the running time of the test (see the description of Roller lifetime).
Criteria: It shall meet the requirements specified by the manufacturing unit (test linear velocity, loading pressure, test running time), and the roller shall have no local concave and convex, degumming, cracking and other phenomena after the test.
Brake lifetime (million times): GB/T24478-2009 >2, Koyo elevator >4
Test conditions: The test is performed at room temperature. The brake is installed on the traction machine platform, the brake is activated by the power switch, and the brake is opened and released.
Test method: Brake action response time should not be greater than 0.5s, test cycle is not less than 5s continuous uninterrupted action test.
Criteria: Normal function, good electrical performance; No maintenance should be carried out during the test, and the performance at the end of the test should still meet the relevant requirements of “GB/T24478-2009 elevator tractor” 4.2.2.2 and 4.2.2.3.
Equipment: Door operator & car door simulation running testing machine.
KOYO Elevator standard: more than 6 million times.
Test conditions: The test is performed at room temperature. The door operator and car door are installed on a fixed platform, and turn on the door operator.
Test method: The door system should run at a speed of 240 times per hour.
Criteria: No fault, normal function, good electrical performance; The wear of wire rope, wire rope guide pulley, door operator belt, accompanying cable and landing door shoes meet the design requirements.
