Numerous pieces of equipment will operate in environments with extreme heat, cold, and humidity as the military, aerospace, and navigation areas evolve. The equipment will have more difficulties in this setting. The equipment's capacity to function is significantly impacted by its stability.
The high and low temperature humidity test chamber, also known as the high and low temperature humidity chamber, is used to evaluate how well materials work in aerospace and navigation systems when exposed to high temperatures, humid heat, and other environmental conditions. Its structure and guiding philosophy are unique in some ways.
The electrical system must be inspected, and the causes of the defects must be eliminated one at a time, if the test temperature cannot exceed the temperature value required by the test during the high temperature test.
If the temperature rises gradually, the air circulation system has to be examined, and the regulating plate's opening condition needs to be noted.
The air circulation runner's rotation must be monitored if the temperature rises too quickly. It is necessary to modify the PID setup parameters if the temperature increases quickly.
It can be assumed that the controller has a malfunction if the temperature rises quickly to the overtemperature protection. The control instrument should be promptly replaced.
It is vital to monitor the temperature change when the low temperature fails to meet the requirements of the experiment. whether the temperature slowly decreases or increases after reaching a given level. The former is typically brought on by the dry equipment's inadequate atmosphere. It is important to pay attention to the equipment's position and the surrounding temperature. If the equipment's operational requirements are not met, a prompt adjustment should be made. If the latter, the apparatus must be examined to determine whether the lab has been dried prior to the low temperature test.If the working area is dry and the test items are placed in the laboratory, determine whether there are too many test items stacked there, which prevents the ventilation cycle from functioning as it should. If the cooling rate is still slow after addressing the aforementioned fault sources, it can be concluded that there is a problem with the refrigeration system. The refrigeration system needs to be refurbished!
Preventive and predictive maintenance are two of the key components of equipment maintenance. Cleaning the laboratory body of the water collecting tray and condensate is one of the two forms of preventive maintenance that must be done once a week. Customers in special housing are required to do maintenance such as flushing the system or washing the medium cooling water pipe or the humidification water pipe. Cleaning the air cooling system's condenser is part of the maintenance that must be done every six months, as is the annual maintenance. Clean the scale from the humidifier's interior, and sweep the AC (high current) contactor's maintenance electrical control cabinet of any dust. Additionally, the compressor's lubricating oil needs to be changed every 2-3 years. The three basic types of predictive maintenance are weekly, monthly, and quarterly maintenance.
Checking the oil body, the color of the oil in the compressor, and the suction and discharge pressure of the compressor are all part of weekly maintenance. monthly upkeep comprises. Verify the temperature of the compressor's exhaust and suction, the liquid mirror's discharge temperature, the condenser's discharge temperature, and the difference in temperature between the water entering and leaving the cold water pipe. Check the equipment's heating and cooling rates. Every three months, check the compressor motor's working current.
Regular maintenance of the equipment not only increases its operational stability and experiment accuracy, but it can also, to a certain extent, lengthen its useful life. Therefore, future maintenance of the high and low temperature humidity chamber should be given careful consideration.
