When the constant temperature and humidity test chamber
cooling slowly, must check the door is closed, constant temperature and humidity equipment laboratory under the condition of the test don't need to open the tail, in case of difference in temperature big harm cooling speed.
Must also check the room temperature is too high, constant temperature and humidity laboratory equipment for implantation working temperature is specified, if the temperature is too high, to find a way to reduce the working temperature, such as air conditioning in the room or open below clapboard with a cooling fan to blow, and then achieve the cooling effect.
Since is temperature, observe the refrigeration units operate in environmental test chamber can start during the whole process, the refrigeration compressor on the natural environment laboratory equipment operation process can start, show from the main switch power supply to the refrigeration compressor normal route of household electrical appliances, household electrical appliances system software level is no problem.
Condenser is overmuch, dust removal of ash cooler, centrifugal fan does not turn observed centrifugal fan in the environmental test chamber operation can start during the whole process, such as centrifugal fan in the environmental test chamber can start operation process, centrifugal fan all showed normal.
Constant temperature and humidity test chamber cooling must also to the refrigeration unit to carry out the inspection, the inspection level 2 set of refrigeration unit temperature R404 refrigeration compressor exhaust pipe and breathing work pressure is slightly lower than standard, and breathe with pressure show time, show that the main amount of refrigerant refrigerating units is not enough.
With the hand to touch the main generator refrigeration compressor exhaust pipe and the breathing pipe, found that the temperature of the exhaust pipe is not high, the temperature of the breathing tube is not low,
, this also shows that the main generator set enough refrigerant.
Load is big examination experiment product artifacts by induction electric testing, and induction, as measured by electrical detection products calorific value of the workpiece.
Such as calorific value within the 300 w for environmental test chamber no harm, but calorific value through communicating slow cooling box temperature can't do the dashboard Settings or refrigeration.
Constant temperature and humidity test chamber for the flameproof equipment, please don't in any flammable or combustible gas used in the natural environment.
It is strictly prohibited to tear open outfit, the production processing, upgrading or servicing of constant temperature and humidity chamber, can appear otherwise cause abnormal posture, the risk of electric shock or fire accident.
The body of the exhaust system to maintain smooth, in case of common failures, abnormal posture, reduce the service life and fire accident.
Constant temperature and humidity test chamber to split open a case if found during the test equipment damage or deformation, please do not apply, should immediately notice equipment maintenance inspection relevant after-sale service staff.
Machinery and equipment installation Settings when pay attention to don't let the dust, knotting, iron pin or other items into the, otherwise will produce incorrect posture or common faults.
Wiring must be appropriate, must carry out grounding device, not grounding device will cause accident getting an electric shock, incorrect posture safety accident and abnormal display information or accurate measurement has great deviation.
On a regular basis to maintain constant temperature and humidity test chamber terminal screws and fixed bracket, please don't in loose under the condition of the application.
The interpretation of the above is the constant temperature and humidity test chamber slow cooling solution, 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 for advice, we will wholeheartedly provide high quality service for you!
