safety devices
1. Compressor pressure is too high.
2. The compressor is overheated.
3. There is overcurrent in the compressor.
4. Pressurized circulating cooling water supply
5. The temperature in the cold and heat stress Test Chamber is too high, resulting in insufficient protection (built-in controller).
6. Prevent the temperature in the temperature shock Test Chamber from being too high or too low, and prevent the door of the Test Chamber.
7. Total power phase sequence and phase loss protection relay, leakage circuit breaker, test power supply control terminal, external alarm output terminal, thermal shock Test Chamber
8. Thermal shock Test Chamber protection switch, high/low temperature chamber overheating protection (built-in controller).
9. Motor temperature protection and relay circulation fan heating.
10. Pressurized air pressure switch, exhaust valve, cold and heat stress Test Chamber.
Conditions of Use
1. Well ventilated and flat floor.
2. There is no substantial vibration near the hot and cold environment test equipment.
3. There is no strong electromagnetic field near the device.
4. There are no flammable, explosive, corrosive or corrosive chemicals or dust near the equipment.
5. Cold and heat shock test equipment for drainage floor drain.
6. The load-bearing capacity of the ground needs to be at least 800kg/m2.
7. Environmental conditions: temperature: 5°C to 35°C; relative humidity: 85%. Air pressure: 86 kPa to 106 kPa.
8. Cooling water temperature: circulating cooling water +30°C.
9. Cooling water pressure: circulating cooling water supply pressure: 0.25MPa 0.4MPa; the design and construction of the cooling water piping system should ensure that the inlet pressure of the chiller at the rated flow is 0.25MPa 0.4MPa; the pressure from the water outlet of the chiller to the cooling water tower The drop is not greater than 0.05MPa.
10. Requirements for the storage environment of the thermal shock Test Chamber: when the equipment is not working, the ambient temperature should be kept within 0-45°C; when the ambient temperature is lower than 0°C, the water stored in the equipment should be drained, So as not to freeze the water in the pipe and rise the bad pipe.
