Constant temperature and humidity test chamber of main components and maintenance methods

Constant temperature and humidity test chamber of the exhaust heat of refrigeration unit ( Cooler) Should be timely maintenance, keep clean. Dust sticky on the cooler can make the refrigeration compressor to get rid of the false alarm caused by high voltage circuit breaker, constant temperature and humidity test chamber cooler should be on time every month maintenance, using wireless vacuum cleaner will be cooler heat wire online adhesion of dust gettering or boot after application of qualitative hard hair brush or by high compressed air blowing mouth clean and dust. Constant temperature and humidity test chamber shell around and at the bottom of the road to keep clean anytime and anywhere, in case of a lot of dust suction in generating set cause accidents and reduce the feature. Feeding mouth or take the test from the chamber of a stove or furnace, not let the door rubber edge touch objects, prevent the rubber edge damaged and reduce the service life. Refrigeration system software is the key to the constant temperature and humidity test chamber, safety inspection once a year, please have all air conditioning copper tube without leakage snow kind of situation, the speaker connector, welding welding mouth, if there is oil leakage, please notice technology professional enterprise or immediate solutions. Distribution of constant temperature and humidity test chamber indoor cleaning maintenance at least once every year, the loose contact will make all machinery and equipment in dangerous working condition, light burned parts, or fire, alarm, accident harm accident risk, when cleaning, please use the dust suction machine will room gettering. Humidifier and scale must be always clean up, in case caused by dirt, the release of steam, generally made an experiment to clear a, dirt get cleared immediately beneficial humidifying tube service life and guarantee the smooth water during cleaning application of copper soft bristle brush to wash water clean. Wet cloth of wet and dry bulb often inspection, when the test cloth surface is not clean or stiff, or in high temperature above 85 ℃ after manipulation, temperature humidity control before again. Via checking if there is no moisture absorption please conversion, associated with the accuracy of the moisture, general test cloth moved around march, when changing a clean towel scrub body temperature measurement, changing a new test cloth should be first hand washing again when the stainless steel sink clean and tidy. Constant temperature and humidity test chamber of tank water level not too high, too high water overflowing product tank or too low to make wet bulb test fabric moisture absorption anomaly, endangering the accuracy of wet bulb. The water probably remain six points can be full. The product tank water level adjustment, can adjust the height of the water box ( Adjust the screw on both sides) 。 The interpretation of the above is the constant temperature and humidity test chamber maintenance method of the main components of the hope can help you, if you want to learn more about information of constant temperature and humidity 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!
