Vacuum atmosphere furnace maintenance required

Environmental testing equipment variety, but the most widely used environmental test equipment for the heat, cold, heat vacuum atmosphere furnace. Hot and cold impact testing machine, for example, to talk about the vacuum atmosphere furnace construction and some of the common faults and troubleshooting.
Some vacuum atmosphere furnace and troubleshooting common faults:
1 in the high-temperature tests, such as temperature changes reach the test temperature value, you can check the electrical system, each troubleshooting. Such as the temperature rose very slowly, we must view the air circulation system, look at the wind circulation damper is open properly, otherwise, check the air circulation motor is functioning properly. Such as temperature overshoot badly then you need to set the parameters of PID tuning. If the temperature rise directly, over temperature protection, then the controller failures, to be replaced control instrument.
(2) during the operation of the test equipment suddenly fails, control instruments corresponding fault appears on the display prompts and a voice alarm. The operator can control the operation of the device using the troubleshooting chapter quickly check out which category failure, you can ask professionals quick troubleshooting to ensure that the test correctly. Other environmental test equipment in use there will be other phenomena, it should be specific phenomenon, specific analysis and troubleshooting.
3 reach the test temperature indicator, then you have to observe the temperature changes, the temperature drop is very slow, the temperature to a certain value, or the temperature tends to increase, the former is necessary to check the laboratory vacuum furnace to make low-temperature test whether the studio before drying, so the studio remain dry and then do the test sample into the working chamber test, the working chamber of the test sample is placed too much, so that indoor air can not fully cycle, the exclusion of the above reasons , it is necessary to consider whether the failure of the refrigeration system, and so we must ask the manufacturer's maintenance professionals.
