Frequently check the hard fast door and confirm whether the voltage of the power supply meets the requirement. The voltage should be 380V + 10% (three-phase four-wire). When cold storage facilities are unnecessary for a long time, the total power supply of the cold storage should be cut off and the facilities of the cold storage should be protected from dampness, dust and other substances.
The hinges, handles and locks of cold storage doors should be regularly lubricated according to the actual situation.
比特棋牌游戏 Electrical equipment maintenance of cold storage facilities should be operated by electricians or people who know how to use electricity。 Any maintenance must be cut off to ensure safety。
Vibration should be avoided during the operation of refrigerators. Vibration not only increases mechanical wear, but also causes loosening or fracture of connecting pipes on the unit. If abnormal noise is found in the running process of the machine, it should be stopped and checked, and then run after eliminating it. The protection functions of refrigeration compressor units have been set in advance, and need not be adjusted.
5、定期检查制冷机组的各连接管、阀件上的连接管是否牢靠，「硬质快速门」，是否有制冷剂渗漏(一般渗漏的地方会发现油迹)。检漏非常实用的方法是：用海绵或软布沾上 洗涤剂,揉搓起沫,然后均匀涂在要检漏的地方,观察数分钟。若渗漏会有气泡发现。在渗漏的地方做上记号,然后做紧固或气焊处理(由专科制冷工作人员进行检 修操作)。
Check regularly whether the connecting pipes on the connecting pipes and valves of refrigeration units are reliable, whether the "hard fast door" has refrigerant leakage (oil stains can be found where the leakage occurs). The most practical method of leak detection is to use sponge or soft cloth to dip in detergent, rub and foam, then evenly apply it to the leak detection area and observe for several minutes. Bubbles will be found if leakage occurs. Mark the leak area and then tighten or gas weld it (it is operated by a specialist refrigeration worker)
The top (roof) of the cold storage facilities should not be stacked with debris。 Otherwise, the cold storage panels will be deformed and affect the thermal insulation function, and keep the passages around the cold storage unobstructed。 Only by ensuring good heat dissipation, can the refrigeration be good。 The location of the cold storage should be kept dry, clean, free of flammable and explosive materials, and ensure that there are no potential safety hazards。 The evaporator must not stack items (reserve certain space) in order to avoid affecting the refrigeration effect。
7、如因空气湿度 过大、化霜间隔时间长、库温设定不正常,所有这些都会导致库内蒸发器上霜层增厚,库温不降。这时就应进行化霜(除霜)处理。并及时观察,等霜层消失立即停 止化霜。稍等片刻后再启动设施。
If the air humidity is too high, the defrosting interval is too long, and the storage temperature is not set properly, all of these will lead to the thickening of the frost layer on the evaporator in the reservoir, and the storage temperature will not decrease. At this time, defrosting (defrosting) treatment should be carried out. And timely observation, such as the disappearance of frost immediately stop defrosting. Wait a moment before starting the facility.
The temperature, temperature difference and other parameters in the cold storage facilities should be set according to the actual situation of the cold storage, and the parameters should not be changed arbitrarily。 When the cold storage is out of the factory, it is customized according to the user's requirements。 The technical parameters of the cold storage should be known before setting the parameters on the controller。
Regularly check whether the power supply voltage is normal (three-phase four-wire), check whether the protection function of the power supply main gate is normal and effective。
