In the blink of an eye, we are familiar with how to maintain the constant temperature and humidity chamber under normal temperature. How to maintain the constant temperature and humidity chamber in the cold winter? Baoditong reveals your secret!
First, the constant temperature and humidity test chamber installation site:
Installation measures Reasonable choice of installation location: dry, no rain and snow dripping.
When the inspection measures are conditional, the special person shall daily confirm whether the insulation material is damaged or not, and the technical confirmation and technical disposal of the steam pipeline.
The alarm measures can be equipped with a sound and light alarm small device for steam leakage or power failure condition, so as to facilitate the discovery and timely rectification of hidden dangers of heat preservation and antifreeze measures.
Second, the constant temperature and humidity box insulation part
1. Select the instrument with insulation device.
According to the type of use of the instrument and the geographical location to be installed, the insulation and antifreeze requirements of the instrument are proposed and submitted to the manufacturer for processing.
Some places in the north have too much temperature difference between day and night, and can reach at night - more than 20 degrees .
2 , insulation with insulation materials
That is, the insulation material is used to wrap the parts that are easy to freeze or freeze.
In winter, it is necessary to inspect and regularly discharge the sewage to prevent damage to the insulation material of the package.
3 , heat tracing measures
The steam heating method uses the tube steam heating to keep warm. Before the steam is supplied in winter, check whether the steam insulation pipe is unblocked or blocked.
Third, constant temperature and humidity box insulation protection box measures
Electric heating belt measures: Electric heat insulation technology is a new type of heating technology that directly converts electrical energy into heat. Install insulation cable, wrap the heating cable around the meter, or stick it inside the instrument cabinet.
Fourth, the maintenance measures of constant temperature and humidity box
1, the fixed cleaned once every 3 months condenser: the use of air for cooling the compressor, condenser fans should regular maintenance and decontamination dust condenser to ensure good heat transfer performance of ventilation; water cooling for cooling the compressor shall, in addition to ensure that the water pressure and water temperature, but also must ensure the appropriate flow. The inside of the condenser is periodically cleaned and descaled to obtain its continuous heat transfer performance .
2 , circulating fan, condenser fan cleaning and balance : similar to the cleaning evaporator , because the working environment of the test box is different , the circulating fan and condenser fan will condense a lot of small particles such as dust , should be cleaned regularly . Waterway and humidifier cleaning : If the waterway is not smooth and the humidifier is fouled , it may cause the humidifier to dry and may damage the humidifier . Therefore, the waterway and humidifier must be cleaned regularly .
3, adhere to the inner wall of the studio and clean every time the test is completed the temperature was set near ambient temperature, work about 30 minutes after power off, and rub.
4, inspection measures maintained by the regional instrument responsible for regular inspection at a predetermined inspection route. During the inspection, it is necessary to check whether the insulation pipeline valve is normal, whether the insulation tank is normal, whether the hydrophobic device is normal, whether the insulation material packaging is intact, and whether the electric heating supply component is normal.
