Introduction to the use of high and low temperature test chamber security sense
During installation of the high and low temperature test chamber shell chassis grounding device, if the environmental test chamber without grounding device, once ZouDian high-voltage electric shock risk will appear; Do not operate in machinery and equipment is not installed well before the machine equipment, ensure the installation before carrying out experiments on edge; If box placed hot specimens, the specimens control switching power supply application plus a switching power supply, please don't apply the machine switching power supply; Shell operation risks caused by electrical flow, do not open the electrical cabinet HouGaiBan lay workers. Such as high and low temperature test chamber is not configured humidification effect, read the article suggests that when the note the different difference between application and regulation; Operation of the high and low temperature test chamber, all kinds of motor, cooling fan under the control panel control, according to the command to start, don't touch the temporary hard in stationary condition electronics, avoid electronics starting suddenly, cause accident harm, certainly must come near rotating component at work, please disconnect the main power master switch, and ensure the safety equipment is in good condition. It is strictly prohibited inside the specimen when move high and low temperature test chamber, specimen will flip or fall; Before applying to ensure high and low temperature test chamber is fixed, the universal wheel off the ground to adjust feet touch the ground, when external force or under high and low temperature test chamber will be surprise move. Laboratory of the high and low temperature test chamber of actual operation, the overheating maintenance set maximum 20 ℃ ~ 30 ℃. Develop test temperature to the preset value, the thermal protection switch power supply of electric heater is terminated, & other; Overtemperature & throughout; Overtemperature warning lights lit, but the cooling fan is still in operation, if the long-term operation and unmanned, preoperative examination as far as possible do over temperature protection, whether it's appropriate [ Humidity protection equipment should be set to 120 ℃. High and low temperature test chamber to change of the water in the air humidifier once each month, to ensure clean water, air humidifier outlet should clean up once a month, in order to ensure the smooth water. Many laboratory application of water, but still looking forward to related each month to clean the glass is not very difficult. External fuel tank must be clear, a year or more to clean up for a long time can clean with soap and water. Cooler should be on time every month maintenance, application of vacuum cooling adhesion in dust sucked into clear cooler network or application of high pressure gas spewing dust. The interpretation of the above is the use of high and low temperature test chamber security sense, hope can help you, if you want to know more about information of high and low temperature test chamber, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!
