Working Principle
The testing machine is a combination of testing machine technology and mechanical transmission technology, sensor technology, automatic control technology. It consists of drive system, control system, measurement system. The drive system is mainly used for the movement of the beam of the testing machine, and the speed of the beam can be controlled by changing the motor speed. The control system is operated by the console control testing machine, and the state of the testing machine and the test parameters can be obtained through the display screen.The measurement system utilizes sensors, signal amplifiers, photoelectric encoders, and data processing systems to perform force measurement, deformation measurement, beam displacement measurement. Drive system, control system, measurement system and other subsystems to coordinate with each other to complete the material pull, pressure, bending and other mechanical performance testing.
Working Conditions
l Operation Temperature：Ambient temperature ~ 45 ℃；
l Relative humidity：20%~80%；
l In an environment free from vibration, corrosive medium and strong magnetic field;
l Installed on a flat basis
l Power supply voltage fluctuation does not exceed 10% of rated voltage.
Instrument Features
l Widely used in the wood-based panels and decorative panels of the internal bond strength, surface bonding strength, tensile strength test, bending test, elastic modulus test, grip force test and plywood shear cut test;
l The speed of the beam during the test can be pre-set by the program, user-friendly;
l Beam and bottom panel through the two ball screw frame structure to ensure that the frame structure rigid;
l All-digital AC servo motor through the no noise synchronous toothed belt, high precision seamless ball screw drive to ensure its smooth load, no gap, high transmission efficiency;
l 5000-line optoelectronic encoder, the relative high accuracy of displacement;
l High precision and high stability of the tire tension and compression strain sensor, coupled with high-precision measurement and amplification system to ensure that the test force of high precision;
l Built-in controller to ensure that the test machine can be specimen deformation, test force and displacement of the closed-loop control;
l With a limit protection function, arrived at the limit after the automatic shutdown, to prevent the collision in the middle of the beam caused by overload or even damage to the sensor;
l Automatically according to the size of the load can be switched to the appropriate range to ensure the accuracy of measurement data;
l Zero adjustment, calibration, storage, etc. without any analog adjustment link, the control circuit is highly integrated;
l Sample process a high degree of automation, the system can achieve the accuracy of the automatic calibration;
l Test end, test data and test curve automatically saved for later retrieval analysis;
l Can be batch test, the same parameters of the sample only a test set;
l With a brand computer to control the software operating system, Chinese and English Windows operating platform, menu prompt, mouse operation, it has the characteristics of high speed, mild interface and easy operation. It can meet the test measurement needs of different materials;
l Consistent with GB, ISO, ASTM, DIN and other relevant domestic and foreign standards.
Instrument Maintenance
l Before using this instrument, please read the instruction manual carefully, understand the operation steps and precautions, avoid the damage caused by improper operation or personal safety accident;
l Test machine is a large precision instruments, should pay attention to water, moisture. Exposed workstations, upper and lower beam parts and attached parts should be coated with anti-rust oil to prevent rust;
l If idle for a long time, at least once a week and move the upper and lower beams, so that beam position, silk mother often activities to prevent rust;
l After the experiment should be promptly cleaned up debris and other dirt, to prevent accidental damage to the instrument, to avoid shortening the life of the test machine;
l After the completion of the test, will be attached to a good, to prevent the loss of equipment for the next use;
l Electrical connection cable and equipment should be careful when connected, moderate efforts, remember not to swipe, hard pull.
