Yangzhou high and low temperature impact test box manufacturer Technical indicators:
1. It must be operated and maintained by special personnel. Strictly abide by the system operation rules to avoid other people's illegal operation of the system.
2、 The maintenance of the system should be convenient to use. The starting and ending time of each operation of the system shall be recorded in the archives (date), type of test and ambient temperature; when the system fails, the failure phenomenon shall be described in detail as much as possible; the maintenance and repair contents of the system shall also be recorded in detail as far as possible.
3、 If the system is not used for a long time, it will affect The effective service life of the system, therefore, every Start up and run at least once every 10 days; do not repeatedly stop the operation of the system in a short period of time; the starting times per hour should be less than 5 times, and the time interval between opening and stopping should not be less than 3Rain; do not open the door of the test chamber system at low temperature to prevent damage to the door sealing belt.
4、 The main box of the system should be protected in use It is not allowed to be impacted by sharp or blunt tools.
5、 The main power switch should be carried out once a month (leakage circuit breaker) action test to ensure that the switch can be used as leakage protector under the load capacity. The specific steps are as follows: first, please confirm that the main power switch is turned to "on", that is, the system is powered on, and then press the test button. If the switch lever of leakage circuit breaker falls down, the function is normal.
6. The leakage, overload and short-circuit protection characteristics of the leakage switch are set by the manufacturer, and can not be adjusted at will in use, so as to avoid affecting the performance; after the leakage switch is disconnected due to short circuit, the contact shall be checked, and if the main contact is burnt seriously or there are pits, maintenance is required.
7、 To ensure that the cooling water supply is normal and clean, every Clean the cooling water filter of the refrigerator once every 30 days. If the local air quality is poor and the dust content in the air is high, the cooling water tower reservoir should be cleaned in about 7 days.
8. The test product placed in the system should be a certain distance from the air intake and exhaust outlet of the air conditioning channel, so as not to hinder the air circulation.
9. Once a year, dust in distribution room and water circuit room shall be removed by vacuum cleaner. Once a month, use dry cloth to clean and dry the water collecting pan of the refrigeration unit.
10、 Operation test of overtemperature protector. Set the temperature of the over temperature protector to be lower than the temperature of the box body E0.0 alarm and beep indicate that the function is normal. After completing the above test, the set value of temperature protection should be set properly, otherwise it may cause improper termination.
Yangzhou high and low temperature impact test box manufacturer Operating procedures:
1. To avoid machine failure, please provide a power supply within the rated voltage range.
2. In order to prevent electric shock or misoperation and failure, please do not connect the power supply before the installation and wiring is finished.
3. This product is non explosion-proof product, please do not use high and low temperature test box in the environment with combustible or explosive gas.
4. Please try not to open the door of the test chamber during the operation of the instrument. Opening the door at high temperature may cause scald to the operator, while opening at low temperature may cause frostbite to the staff, and may cause the evaporator to freeze and affect the refrigeration effect. If you must open the door of the test chamber, please do a good job of relevant protection work.
5. It is forbidden to dismantle, process, transform or repair the high and low temperature test box without authorization, otherwise there will be abnormal action, electric shock or fire hazard.
6. The ventilation hole of the machine body should be kept unobstructed, so as to avoid malfunction, abnormal action and reduce service life.
7. Please do not damage the machine when it is opened or powered on.
8. When installing the machine, pay attention not to let dust, thread, scrap iron or other objects enter, otherwise, wrong action or failure may occur.
9. The wiring must be correct and must be grounded. Ungrounded may cause electric shock, wrong action accident, abnormal display or large measurement error.
10. Check the terminal screws and fixing frame regularly. Do not use them when they are loose.
11. During the operation of the instrument, the power input terminal cover must be installed on the terminal board to prevent electric shock.
