Failure analysis of artificial climate incubators

Failure analysis of artificial climate incubators

In the fields of biology, agriculture, health care and other production and scientific research, in order to ensure the necessary living conditions of certain organisms and meet the indoor observation needs of biological growth and development, there must be a device to simulate various microclimate environments. The intelligent artificial climate chamber is in accordance with the above requirements. Developed. Intelligent artificial climate box is also called artificial climate incubator. It can be controlled by artificially controlled lighting, temperature, humidity, air pressure and gas composition and other environmental factors. It is not limited by geographical conditions, seasons and other natural conditions, and can shorten the research cycle. It has become an important equipment for scientific research, teaching and production. In the process of using this device, further research and discussion of the device, found that there will be some problems in the use of the process, these problems are summed up and analyzed, and the processing methods are brought together, Hope to help users.

malfunction

the reason

deal with

The crew does not work

Power failure; fuse blown; poor electrical outlet contact.

Wait until there is electricity before use; replace the fuse; reinstall or tighten it.

Poor cooling effect or no refrigeration

Refrigerant leaks; Capillary blockage; Axial fan does not turn.

Professionals to overhaul; please professional inspection; testing or replacement.

Poor temperature effect

The culture items are too dense; the ambient temperature is too high or too low; the number of door openings is frequent; the axial fan does not turn; the temperature setting is not set as required.

Leave a certain gap; ambient temperature 0-30 °C; reduce the number of open the door; replace the fan; reset the debugging parameters.

Not heated

Heating tube or relay damaged; thyristor damaged.

Replace; Replace.

Running out of schedule or not running according to set parameters

It may be 24CO2 damage

Professional replacement

The key does not work

The keys are damaged; the socket is loose.

Replace the panel; open the top cover and insert it tightly.

Can't hear relay sound when working

Damaged optocoupler; damaged relay.

Professional replacement professional replacement

Humidification indicator light but not humidified

The humidifier cuts water; the humidifier is damaged.

Add water; replace

People touch the shell with electricity

No ground or poor grounding

Prohibit the use of re-installation of grounding wire

This problem may occur during operation: When the temperature sensor fails, when the measured temperature is higher than 60°C or open circuit, the temperature indicator will show “□□□”. When the temperature is lower than -5°C, the bottom row of the temperature indication window shows "□□□". When the humidity sensor fails, the lower display of the indicator window shows "□□". In the above case, please check the wiring carefully. If there is no problem with the wiring, replace the sensor.
