1, vibrator stroke / mm 1 ± 0.02: using a reflective linear photoelectric encoder(grid ruler) and reading grating sensor to control the stroke. The control process directly outputs digital signals, does not produce displacement changes in the process control, has self-calibration function, and is not adjusted for the rest of life. 2, with high frequency reciprocating stroke limit protection device.

The direct output of digital signals in the control process will not produce displacement changes in the process control, and will not be adjusted for the rest of the life. The high frequency reciprocating stroke limit protection device fixes the shaft rod under static conditions to prevent damage to the spindle when installing the test parts. The device effectively protects the vertical of the shaft rod and the vibrator, and at the same time guarantees the grating reading counter. The corresponding position of the ruler, Prevent the influence of external force damage on the stroke control.

Computers and controllers

1, to ensure the independence of the controller and the computer, if the computer failure, can be calculated at any time with any other brand instead of use.

The diesel lubricating high-frequency reciprocating tester controller is connected to the computer for the data line. No control chip, control module, and board card are installed in the computer chassis. Therefore, when the computer fails, the user can replace any other brand computer at any time. After installing the test operation software, you can use it.

Thermothermal constant humidity control instrument:(equipped with enhanced drying tube) 1) The system test machine host box and constant temperature and humidity control instrument adopts a split type connection to avoid resonance; The constant temperature and humidity control instrument is a separate instrument unit. Its characteristics are that after setting the ambient temperature and humidity, it can be automatically adjusted according to the set values, and ensure that the temperature and humidity values in the entire test process meet the steady state error values of its set values. (2) When the ambient temperature reaches 35 °C -40 °C, the system must be reduced by 15 °C within 10 minutes and can accurately control the temperature in the test box, with a control accuracy of 0.1 °C. (3) When the ambient humidity is 5 % -95 %, the constant temperature and humidity system must adjust the internal humidity of the constant temperature and humidity box to a set value within 2-3 minutes. (4) The constant temperature and humidity system must fully meet the requirements of the latest version of the IS0 12156.1 international test method standard for temperature and humidity. Thermothermal constant humidity test box: Thermal insulation sandwich test box: temperature and humidity control device interface and temperature and humidity transmitter.

1、Operating ambient temperature: 17 to 35 °C, operating ambient humidity: 5-95 %; (Temperature and humidity can be set and adjusted by self) 2、Compression mechanism cold constant temperature and humidity system: This system includes two parts of the test constant temperature and constant temperature and humidity control instrument. It is a split type connection to avoid the resonance of the entire tester mechanical system due to the high frequency vibration of the gas pump and other devices. The system uses an automatic constant temperature and humidity device to control the temperature and humidity value of the test box accurately 3, fully automatic temperature and humidity control device(can accurately control the temperature and humidity in the test box, and separate from the main body of the test machine to avoid resonance.

In the test operation interface, the standard map of the environmental allowable range(temperature, humidity) in theASTM D6079-2018 standard can be obtained at any time; The software control platform can also automatically control, data acquisition, data real-time monitoring, data calculation, forming reports, parameter calibration and data browsing after testing. In the test report, the speckle image can be added to the report to form a complete test report.

Test operation software platform: The system includes test operation, test automatic control, data real-time monitoring, data calculation, formation report, parameter calibration and data browsing after test are all completed in the software. At the same time, the allowable division(temperature and humidity) of the test environment in the ASTM D6079-2018,ISO 12156.1-2018 standard is drawn into a standard template. During the test process, it can be called up at any time to facilitate comparison with the standard requirements to obtain more accurate test data.
