Description
Test Equipment for Sofa Durability
Model：KH-FM-8129
Application：The test machine is suitable for single sofa, double sofa, three-seat sofa; testing the durability of the seat, back and armrest of the sofa, and automatically testing the back looseness, the residual looseness of the back, the looseness of the handrail, and the remaining looseness of the handrail.
Executive Standard：
QB/T1952.1-2012《Upholstered Furniture Sofa》
Characteristics：
- High resolution digital controller; closed loop control. The fatigue output pressure sensor is installed at the output end of the cylinder. The cylinder air pressure control is controlled by the imported gas-electric proportional valve. The output power of the cylinder can be controlled through the touch screen input. A truly controllable high-precision test instrument is realized.
2、With Real-time force-time curve display and real-time speed display
3、Control software: real-time dynamic motion display of test axis during test, strong editability
4、The high-level part is adopted with automatic vertical direction measurement. No need the cantilever type. It reduce the cantilever type self-contained error
5、The number of trials can be set and the number of trials can be displayed directly in real time.
6、Whether the automatic test piece is damaged or not, and it automatically stops the test and retains the test result. After a sudden power failure or human shutdown, recall or restart again, it proceed the operation according to the parameters set before the power failure，which can ensure the continuity and stability of the test.
Technical Indicators
1、This machine meets the test requirements of QB/T1952.1-2012
2、Control and detection methods: computer control, fully automatic test results, one-button control full automation operation and manual test mode; equipmented with seat surface durability test, back durability, armrest durability, seat height and seat surface compression volume, each mode can be controlled independently.
3、The height measuring device does not have a cantilever structure, and is a vertical structure, which eliminates the possibility that the height measuring device generates its own error as the measuring force increases.

11）Closed-loop Control: The fatigue output pressure sensor is installed at the output end of the cylinder. The cylinder air pressure control is controlled by the imported gas-electric proportional valve. The output power of the cylinder can be controlled through the touch screen input. A truly controllable high-precision test instrument is realized.
12）The cylinder adopts the shaft without rotating the cylinder to reduce the friction caused by the guide and improve the test accuracy and stability.
13）The Electric power proportional valve adopts imported brand
6、Height Measuring Device：
1）Load Capacity:0-1000N
2）Height Measurement Range500mm；Accuracy：±0.1mm；
3）Height Measuring Block：Measuring surface is a smooth rigid cylinder；
4）Measuring Pad Diameter：100mm,Chamfer R10；
5）Pad Force Rate：100±20mm/min；
6）Vertical Downward Force：4N、40N、200N、250N
6）Height Measuring System: The force value is set by the software, and the constant speed is applied vertically downwards to be directly connected to the computer。
7）Displacement measurement method：Using high-accuracy displacement meter; that is, automatic measurement distance
8）control method: Computer automatic control
9）controlling software: Using LABVIEW to develop special control software, it can realize multi-channel closed-loop control; fully automatic control and automatic measurement in test process with good professionalism, high reliability, easy upgrade, etc., and with the development of testing and control technology of testing machine continuous upgrade and improvement of test standards
10）Acquisition System：USA National Instruments with High Speed Acquisition 24 Bits
11）Data Saving：Automatically save all test data, convenient to call at any time
12) computer control; automatic measurement of compression amount a, compression amount b, and compression amount c back loose momentum, back residual looseness, handrail looseness, handrail residual looseness and other standard specified measurement parameters.
Fully automatic operation: One-button automatic operation, the test piece is placed well, as long as the execution button is pressed, the test process is automatically completed according to the set program.
7、Safety Equipment:
- a) Capacity Maximum Setting: When the power sense reaches this value, it will automatically stop.
- b) Maximum displacement setting: When the displacement reaches this setting, it will stop automatically.
- c) The circuit switch is automatically detected, and the leakage automatically stops.
- d) Breakpoint shutdown: Automatically stops when testing breakpoints or damage.
- e) Upper limit limit micro-motion device: When the upper limit point or lower limit point is reached, the photoelectric switch will turn off the power supply and stop automatically to prevent instrument damage caused by improper operation.
