Troubleshooting method of constant temperature and humidity Test Chamber
Abstract:
文章介绍了恒温恒湿试验箱常见故障的处理方法。对于冷冻机不运转的情况，可能原因包括插头接触不良、保险丝烧断、电压过低等，对应的解决措施是检查电源、保险丝和温度调整器等。对于冷冻机持续运转但冷却效果不佳的问题，可能是通风不良或温度调节器设定不当，需要调整安装位置或检查门封。若设备发生杂音，可能是内部器件摆放不当或基础不稳。对于高温电热系统失效，需检查高温保护开关、电热管或温度设置。
When using constant temperature and humidity Test Chambers, we will inevitably encounter situations that require regular maintenance or machine failures. Today, Xiaochao shares a few failure phenomena and solutions for constant temperature and humidity Test Chambers in daily life. Friends who need them quickly look down.
1. The freezer is not running
| reason | Countermeasures |
| (1) Poor contact between plug and socket | check plug |
| (2) The fuse of the socket is blown | Check Outlet Fuse |
| (3) Whether the voltage is too low | Measuring supply voltage |
| (4) Whether the indicator button of the temperature regulator is in the off position | Check the indicator button of the temperature regulator |
| (5) Whether the overload relay is burnt out | Check overload relay |
| (6) Motor burned out | check motor |
2. The refrigerator has been running but the cooling degree is not enough
| reason | Countermeasures |
| (1) Whether the ventilation of the condenser is poor or it is close to the stove, electric stove, or a place exposed to direct sunlight | Check the installation position and adjust the position |
| (2) The adjustment position of the temperature regulator is wrong | Check the position indicated by the temperature regulator |
| (3) The door gasket is leaking, or the door is not closed tightly | close it again |
3. Noise occurs
| reason | Countermeasures |
| (1) The internal disk storage is badly placed | Check internal drives |
| (2) Poor foundation | choose another location |
| (3) Improper placement | check level |
| (4) Whether the piping vibrates with each other | Check pipeline |
4. The high temperature electric heating system does not work
| reason | Countermeasures |
| High temperature protection switch tripped | Check the circuit of the high temperature electric heater |
| The heating tube is damaged | redress |
| Temperature regulator setting is too low | reset |
