Five skills of prolonging service life of high and low temperature test chamber

Source: website release time: May 28, 2019 08:36:00 reading: 597 Do you know how to use the high temperature box in real life to extend the life of the items? The following five points can help you extend the service life of high and low temperature test chamber.

(1). Check the over temperature protector in high and low temperature test chamber: when the high and low temperature humidity and heat alternating test box is running, set the high value of the over temperature protection plus 20 ℃ ~ 30 ℃. When the temperature in the test box rises to the set point of the over temperature protection, the power supply of the heater will stop. If the "overheat" warning light is on, but the fan is still running. If it has been running for a long time and unattended, please make sure to check whether the over temperature protector is set properly [the setting of the over temperature protector is 120 ℃]

2. Dust removal of condenser in high and low temperature test chamber: the condenser shall be maintained regularly and monthly, and the dust attached to the condenser heat sink mesh shall be removed by vacuum cleaner or sprayed with high pressure air.

(3). Inspection and maintenance of humidifier in high and low temperature test chamber: the water storage in the humidifier should be replaced once a month to ensure the water quality is clean, and the humidifying water tray should be cleaned once a month to ensure smooth water flow.

(4). Inspection and adjustment of wet bulb water level in high and low temperature test chamber: the water level of water collecting cylinder shall not be too high, which will cause water overflow into the water collecting cylinder or too low, which will cause abnormal water absorption of wet bulb test cloth, and affect the accuracy of wet bulb. The water level can be kept at about 6% full. The height of the water box can be adjusted by adjusting the water level of the water tank.

5. Replacement of wet bulb test cloth for high and low temperature test chamber: when the surface of test cloth is not clean or hard, or after the temperature control is completed, the test cloth must be replaced before the temperature and humidity sphericity control is continued. The test cloth should be replaced once every three months. When replacing, the temperature measuring body should be wiped with cleaning cloth, and the new test cloth should be cleaned first.

Because the high and low temperature test box belongs to live product, it has certain danger. Therefore, once the equipment is found to be out of order, for the sake of safety, the operators should not dismantle or replace the parts at will, and should * time the original manufacturer to carry out on-site inspection of the cause of the failure, so as to avoid unnecessary trouble.

The above five points are high and low temperature test box life extension skills, I hope to help you, in the use of these skills must pay attention to these skills, so as to save costs and create income.
