Product introduction

The microprocessor controlled electronic thermal insulation material testing machine is a new door-type double-space material testing machine. This testing machine is specially developed for various mechanical property tests of insulation materials. The system adopts microcomputer closed-loop control, and it has a wide and accurate loading speed and force measurement range and has a high load and displacement measurement and control accuracy and sensitivity. This equipment applies to metal, thermal insulation materials, adhesive, tube, profile, space flight and aviation, petrochemical, waterproof roll, wire and cable, textile, fiber, rubber, ceramics, food, pharmaceutical packaging, geotechnical cloth, thin film, wood and paper manufacturing and product quality supervision departments at all levels, and it also applies to the teaching demonstration work of secondary technical schools and junior colleges. The design of host of testing machine is featured by beautiful appearance, convenient operation and stable and reliable performance, no pollution, low noise, and high efficiency.

This machine adopts a computer for control, acquisition, analysis and processing of test data, drawing of stress-strain, force-time, stress-displacement curves, and it can print test reports; this machine adopts the latest control technology, and the AC servo speed regulating system with stable performance and motor as the drive system; the synchronous toothed belt deceleration system specially designed and ballscrew pair drive the moving beam motion of testing machine, and the testing bench can run at the speed of 0.001～500mm/min, with high speed regulating precision. When the high-precision spoke-type sensor is used on the force measuring source, its precision can reach 1%, with high sensitivity, and the whole system can reach the precision of Grade 1; it is equipped with a commercial computer of leading brand as controlling machine, for setting of test parameters, controlling of working condition, data collection, processing and analysis, display and printing of test results; the measuring control system is configured with the SMART TEST control system. The control and data processing software based on database technology and with Windows as operating platform replaces the traditional Nixie tube and oscilloscope with the virtual instrument technology, realizing the screen display of test force, peak value of test force, beam displacement, specimen deformation and test curve, and all test operations can be completed by means of mouse input on the computer screen, with good human-computer interface and convenient operation; the two-channel full digital program-controlled amplifier plugged in the PC machine realizes the automatic switching, zero setting and calibration of physical zero setting and gain adjustment, as well as automatic shifting, zero setting and calibration of test force measurement in the real sense, without any analog adjustment link, and with high integration of control circuit, potentiometer and other mechanical adjustment devices are completely cancelled, with simple structure and reliable performance. The comprehensive application of the said technologies guarantees that this machine can realize the closed-loop control of test force, specimen deformation and beam displacement, and it can realize constant force, constant displacement, constant strain, constant-speed loading cycle and constant-speed deformation cycle tests. Users can use the PC machine expert system for independent setting of such control modes as constant stress, constant strain and constant displacement, and various control modes can be smoothly switched.
