How to maintain constant temperature and humidity room and other laboratory equipment? Many friends do not know how to maintain the laboratory equipment in a constant temperature and humidity room.
1. The refrigeration systems such as condensers, copper pipes, evaporators, and compressors should be cleaned regularly, and dust should be removed in time.
The refrigeration system is the core component of the machine, and it is the condenser that should be maintained on a monthly basis. Use a vacuum cleaner or a brush to suck and remove the dust attached to the condenser's heat sink or use high-pressure air to spray the dust. This can avoid the equipment. Overpressure, overload, etc. occur.
2. The over-temperature protector in the box should be checked regularly
When the constant temperature and humidity room test chamber is running, the maximum setting value of over-temperature protection is increased by 20℃~30℃. When the temperature in the test chamber rises to the set point of over-temperature protection, the power supply of the heater stops, "OVERHEAT" The over-temperature warning light is on but the fan is still running. If it is running for a long time and is left unattended, please check the over-temperature protector before operation to see if it is properly set (the setting of the over-temperature protector is 120℃).
3.the wet ball gauze in the box should be replaced as appropriate
When the surface of the wet ball gauze is not clean or hard, or the equipment is not used for a long time, the wet ball gauze needs to be checked or replaced before the next humidity test. The manufacturer recommends replacing it every three months (the gauze must be clean). This can prevent the device from showing 100% humidity, or the humidity cannot be increased or fluctuates greatly.
Fourth, the cleaning and maintenance of the inside and outside of the constant temperature and humidity test box
1. The test chamber should be cleaned of internal impurities before manipulation
2. The power distribution room is cleaned at least once a year to prevent dust in the air from being adsorbed on the surface of the machine or on the condenser, evaporator and other accessories.
3. The exterior of the cabinet must also be cleaned more than once a year. When cleaning, wipe it with soapy water first, but do not use corrosive liquids.
5. Inspection and maintenance of humidifier in constant temperature and humidity test chamber
The water storage tank in the humidifier should be replaced once a month to ensure that the water quality is clean. The humidified water must be purified water. Because the tap water has more impurities, it is easy to block the water pipe and affect the progress of the experiment. The humidification water tray should be cleaned once a month to ensure smooth water flow.
