1) Leak detection of the evaporator of the
flake ice machine is often carried out. Leakage is a common failure phenomenon of evaporators, and you should pay attention to frequent leak detection during use.
When the ammonia evaporator leaks, it has a pungent odor, and there is no frost at the leak point. Phenolphthalein test paper can be used to check the leak, because ammonia is alkaline, it turns red when it meets phenolphthalein test paper. When you look at it, it is usually a leak point where there is no frost in the evaporator. You can also use soapy water to find the leak at the leak.
The leak inspection of the evaporator of the flake ice machine can use a halogen lamp and a halogen leak detector, or use soapy water to find the leak. When checking, you can first check whether there are oil traces on the evaporation pipe. Because freon and oil are mutually soluble, when freon leaks, the oil will also leak out from the leakage point. Therefore, where there is oil, it will leak. When a halogen lamp is used for leak detection, if there is a Freon leakage somewhere, the flame of the halogen lamp burning changes from blue to green, light green, grass green, purple green, purple and other colors to judge the amount of Freon leakage. If the flame is dark green or purple, the phosgene in the flame is poisonous, and this method cannot be used for long-term inspection. In this case, soapy water can be used to check for leaks. For minor leaks, a halogen leak detector should be used for leak detection.
2) Frequently check the frosting condition of the evaporator of the flake ice machine. When the frost layer is too thick, it should be defrosted in time. When the frost is abnormal, it may be caused by blockage, and the cause should be found and eliminated in time.
3) When the evaporator is out of service for a long time, it is advisable to bump the refrigerant into the accumulator or condenser, and keep the pressure of the evaporator at about 0.05MPa (gauge pressure). If it is the evaporator in the salt pool, it needs to be flushed with tap water. After flushing, fill the pool with tap water.
