Analysis and Elimination of Thermal Shock Tester
Thermal shock test machine in the hot and humid test, the actual humidity will reach 100% or the actual humidity and the target humidity vary greatly, the value is much lower, the former phenomenon: the wet bulb sensor may be caused by drying gauze, it would Check the wet bulb sensor water tank is water, the water level in the tank is controlled by a water level controller, check the water level controller water supply system is normal water supply, water level controller work is normal. Another may be the wet bulb gauze due to the use of a long time, or the quality of water supply purity of the reasons, will make the gauze hard, so that gauze can not absorb water and dry, as long as the replacement or cleaning gauze can rule out the above phenomenon. The latter phenomenon is mainly the humidification system does not work to see the humidification system of the water supply system, the water supply system whether there is a certain amount of water to control the water level of the humidifier boiler water level is normal, humidification boiler water level is normal. If everything is normal, it is necessary to check the electrical control system, which requires professional maintenance personnel for maintenance. Test equipment in the constant temperature test run process suddenly fails, the test box control instrument appears on the corresponding fault display prompts and voice alarm tips. The operator can quickly check out which type of fault is in the chapter on the troubleshooting of the operation of the device.
Thermal shock test machine in the course of a sudden test failure, the control instrument appears on the corresponding fault display prompts and voice alarm tips. The operator can quickly check out which type of fault is in the chapter on the troubleshooting of the operation of the device. The operator can quickly troubleshoot to ensure that the test is performed normally. Other environmental testing equipment in use there will be other phenomena, it is necessary to specific phenomena, specific analysis and exclusion.
Make sure that the power cord is properly installed and properly connected to the ground to confirm whether the dry bulb overtemperature protection switch is set at the maximum temperature of the equipment plus 10 ~ 20 ℃. This is the safety structure of this equipment. Check if the wet bulb overtemperature protection switch is set at 150 ° C. Only when the temperature test should be removed gauze, if the gauze at 85 ℃ above the high temperature operation, the next operation should be replaced before the gauze, or may no longer absorb water, changing gauze, please wash your hands.
Thermal Shock Tester but also regular maintenance, refrigeration system, regular cleaning of the condenser, the activities should be due to manual lubrication, electrical control system, regular maintenance and inspection, etc., these work is essential.
