Causes and countermeasures of common failures of constant temperature and humidity chamber

Date: Jan 04,2023 Views: 147

Summer with the daily temperature continues to rise, people's body surface temperature under the attack of wave after wave of heat wave, similarly, the installation position of machinery and equipment, the ambient temperature can not be too high, if the heat dissipation is not good, easy to cause overpressure of constant temperature and humidity chamber compressor and affect the use of equipment, summarize the following reasons and countermeasures for common failures of constant temperature and humidity chamber:

 

First, compressor overpressure → bad heat dissipation, condenser blockage, fan failure, ring temperature is too high

 

Two, compressor overload → heavy load, protection component failure, power phase, compressor damage

 

Three, large temperature fluctuation → most of the sample or the sample itself is too hot

 

Four, the cooling is too slow → the circulating fan in the chamber does not turn, the ambient temperature is too high, the ventilation is poor, clean the condenser

 

Five, the temperature is not controlled → the heating solid state is broken down or the controller is damaged

 

Six, humidity can not humidify → humidifying tube is damaged, humidifying solid state relay is damaged, adjust the humidity temperature limit properly

 

Seven, abnormal humidity display → whether high temperature (≥100℃) test, after high temperature test, the gauze will be cleaned again

 

Of course, if you want to extend the life of the equipment, regular maintenance and maintenance is not small, especially the condenser, which is an important part of the refrigeration system, must keep its ventilation and clean.

 

Huanyi Instrument temperature and humidity control chamber (constant temperature and humidity chamber) is the latest series, powerful, can achieve high and low temperature alternating, constant humidity and heat, rise and fall slope controllable, a variety of cycle mode, program series and other complex tests. Temperature control using the company's latest patented technology - cold demand technology, compared with the traditional BTHC (essence is the mutual heat and cold constant temperature) control mode, more power saving, lower use cost; Humidity operation adopts frost - free control, suitable for long-term operation, stable performance and mature technology. Constant temperature and humidity chamber suitable for electronic, electrical, communication, instrument, vehicle, plastic products, metal, chemical, building materials, medical, aerospace and other industries product testing quality use.
