Performance Test System of Floor Spring

Test equipment function：

    The equipment is designed to test and record opening and closing moment of Floor Spring continuously in double directions from 0 degree to 180 degree opening and from 0 degree to -180 degree opening.

1．Floor spring is installed on the test door;

2．The servo motor open the test door from 0° to o the maximum opening angle or 180°  under speed of

     1° /s, and record the opening force and opening degree during the process;

3．Then, the motor reverses and slowly releases the door leaf, and the doorclose from 180 ° to 0° under

     the action of the door closer，Record the closing force and degree of the closing process;

4．The opening / closing process come out "force vs angle" curve (as shown in Figure 1);

5．Calculate the dataand generate the performance test report of closing force value according to EN

     1154:1997+A1:2006,ANSI/BHMA A156.4:2019 (As shown in Figure 1) and test method and report for

     QBT2698-2016;;

6．Set another open direction and repeat the test
