Fault alarm function: according to the technological requirements, a vacuum furnace brazing furnace temperature display abnormal low (or overtemperature), thermocouple damaged or open circuit fault alarm functions, such as when there is abnormal or fault occurs, the fault alarm signal corresponding to the temperature of the point of failure and the touch screen display signal will appear flashing at the same time, to remind the operating personnel in a timely manner to adjust the brazing furnace temperature and to deal with failure.
Vacuum boiler working principle: using the characteristics of low water under the condition of low boiling point, rapid heating sealing furnace heat medium filled in water, high temperature steam, the heat medium water boiling evaporating out water vapor condenses on the heat exchange tube heat exchange tube in cold water, hot water supply.
Equipment in the process of the test run fails suddenly, corresponding to appear on the control instrument error shows that prompt and voice alarm prompt. Operators can control equipment operation using the troubleshooting chapter of the quick check out what kind of failure, can ask professional rapid troubleshooting, to ensure the normal test. Other environmental testing equipment in use there will be other phenomena, that is about the specific phenomenon, specific analysis and ruled out.
In the high temperature test, such as temperature change can not meet the test temperature, can check the electrical system, one by one. Such as temperature rises slowly, will see the wind circulation system, to see if a driving cycle of damper opening to normal, on the contrary, will check whether the wind circulation of motor operates normally. Such as temperature overshoot as you will need to set the setting of PID parameters. If the temperature rise directly, over temperature protection, then, the controller is out of order, must change the control instrument.
