LT-JJ26 Computerized sofa comprehensive testing machine / computerized sofa testing instrument / Computerized sofa durability belt height tester

The product description

The mechanical property test of sofa basically is to test the durability of the seat, back, armrest of sofa. During the test, the loading module of a certain shape and quality will be loaded in a specified loading form and frequency, respectively, on the surface of the seat, back and armrest. This test method is to simulate the daily use of the situation of sofa, to test its bearing capacity to long-term repeatable load. This machine can automatically test the height of the seat, the compression of a, b and c, and the offset of the back and handrail, which can avoid the error of manual height measurement, and save the working time.

Product features

1. Control mode: computer control, executive force automatic control; When the specimen is damaged, the pressure will be released automatically and the cylinder will return to its original position, showing the force value and sub-values at the same time. Automatic stop and return after reaching the set number. High precision displacement meter automatic ranging;

2. Full-automatic operation: single-key full-automatic operation; once the specimen is placed, press the "execute" key and the test process will be completed automatically according to the set procedure;

3. Safety device :1). Maximum capacity setting value 2). Maximum displacement setting value. 3) circuit switches are automatically detected and leakage is automatically stopped. 4). The breakpoint stops. 5). Upper limit and lower limit fretting device:

4. Control module: set load, times and time, set failure test, test date and intermittent setting
