In the process of application of hot and cold impact test chamber, on all kinds of knobs for panel, the power switch, inside diameter scale rotation or adjust the position, slowly, not fierce wild.
When touching the rotating difficult, can not turn hard pull hard, just in case in loose, slide, rupture and other human factors common failures, then should disconnect switch power to carry out maintenance.
Instruments and equipment to connect power work, should be forbidden on the shell.
For heavy xenon lamp aging test chamber, the conditions on the power supply work, do not use drag and drop, in case of vibration damage.
For output, the plug-in type cable, or take away from should hold waterproof casing, not immediately involved cables, in case of break the internal transmission line.
To take great hot and cold impact test chamber, rated power should guard against in the process of application, disconnect switch power supply to start the application again, as soon as otherwise it may cause the fuse melts off.
If must be, should start again after waiting for refrigeration equipment.
The output end of the frequency meter, not immediately connect with ac voltage of power supply circuit, in case of power flow is introduced into hot and cold impact test cases of low characteristic impedance type attenuator burned attenuator resistor.
When necessary, should work string a relatively standard after the coupling capacitor voltage and moderate capacity, the data signal to the voltage to test the power supply circuit.
Application of cold and hot shock test chamber to carry out the inspection work, to join & other;
Low potential difference & throughout;
The earth wire terminals (then join & other;
High potential & throughout;
The terminals (
such as the probe is on the contrary, test end to remove the high voltage terminal, then remove the low potential terminal blocks, or it will cause equipment load, and smash watt-hour meter.
Hot and cold impact test cases into powder layer, ultra-low temperature area, test area three part of the window of the heat insolation and the choice of different thermal storage and cold storage effect, selecting hot air cooling way conversion method guide into the sample, do hot cold impact test.
Hot and cold impact test chamber is a metal material, plastic, rubber, electronic devices required testing equipment
, raw materials, such as manufacturing industry to test raw material structure or polymer materials, in a flash of the extremely high temperature and cryogenic natural environment can withstand level continuously, can in the shortest possible period within the test specimens because of the heat from the cold caused by chemical reaction or physical damage.
Is the use of hot and cold impact test case of the interpretation of the above notice, hope can help you, if you want to learn more about information about hot and cold impact test chamber, welcome to the online consulting service or call the company service hotline (
