In order to make the system safe and trouble-free. Regular inspection and maintenance can not only solve the problem in time and keep the system in the best working condition.
1: The walk-in temperature and humidity test chamber must strictly abide by the system operation regulations to avoid others from violating the operating system. The equipment system must be operated and maintained by a dedicated person.
2: The system use file should be established to facilitate the maintenance and repair of the system. The use file should record the start and end time (date) of each operation of the system, the type of test, and the ambient temperature. When the system fails, the failure phenomenon should be described as detailed as possible. The content of maintenance and repair of the system should also be as detailed as possible. To record.
3: The main box of the walk-in temperature and humidity test system, should pay attention to protection during use, not to be strongly hit by any sharp or blunt objects.
4: The walk-in temperature and humidity test system is not used for a long time, it will affect the effective service life of the system. Therefore, the system must be turned on at least once every 10 days. Do not stop the system repeatedly for a short period of time. The number of start-ups per hour should be less than 5 times. The time between each start and stop should be no less than 3rain. Open the door of the walk-in temperature and humidity test system to prevent damage to the door sealing tape.
5: The test product placed in the walk-in temperature and humidity test system should have a certain distance from the suction and exhaust ports of the air-conditioning channel, so as not to hinder the flow of air.
6: To ensure that the cooling water supply is normal and clean, the cooling water filter of the refrigerator is cleaned every 30 days or so. If the cooling water tower of the water supply is cleaned once the local air quality is relatively poor, the dust content in the air is very high, generally it should be about 7 days Clean the cooling water tank.
7: Conduct the main power switch (leakage short-circuiter) action test regularly every month to ensure that the switch can be used as a leakage protector under the load capacity. The specific steps are: first make sure that the main power switch is turned to "ON", that is, the system is powered on, and then press the test button. If the leakage circuit is broken and the switch lever of the device falls down, this function is normal.
8: Action test of over-temperature protector. Set the temperature of the over-temperature protector to be lower than the temperature of the cabinet. If an E0.0 alarm and a buzzing sound appear, it indicates that its function is normal. After completing the above test, the temperature protection setting value should be set appropriately again, otherwise it may cause inappropriate suspension.
9: The leakage, overload, and short-circuit protection characteristics of the leakage switch are set by the manufacturer. They cannot be adjusted randomly during use to avoid affecting the performance. After the leakage switch is disconnected due to short circuit, the contact should be checked. If the main contact is burned seriously or If there are pits, maintenance is required.
10: Once a year, use a vacuum cleaner to remove dust from the power distribution room and water circuit room. Once a month, use a dry cloth to clean up the water in the drip tray of the suction and freezing unit.
