In life, when talking about water-cooled screw chillers, perhaps everyone is not sure what this is. But in fact, water-cooled screw chillers are used in many machines and equipment on the market. Then, how to maintain the specific water-cooled screw chiller? Below, let me introduce you to Xiaobian.


The cooling water of the water-cooled condenser is an open loop, and the tap water generally used is recycled through the cooling tower. When the content of calcium salt and magnesium salt in the water is large, it is easily decomposed and deposited on the cooling water pipe to form scale, which affects heat transfer. Excessive fouling also reduces the flow cross section of the cooling water, reduces the amount of water, and increases the condensing pressure. Therefore, when the water quality of the cooling water used is poor, the cooling water pipe is cleaned at least once a year to remove scale and other contaminants in the pipe.


The drying filter is an important part to ensure the normal circulation of the refrigerant. Since water and refrigerant are incompatible with each other, if the system contains moisture, it will greatly affect the operating efficiency of the unit. Therefore, it is very important to keep the internal drying of the system. The filter element inside the drying filter must be replaced regularly.


The condenser and evaporator on the screw chiller belong to the pressure vessel. According to the regulations, the safety valve should be installed on the high pressure end of the unit, that is, the condenser body. Once the unit is in an abnormal working environment, the safety valve can be automatically vented. Pressure to prevent high pressure damage to the human body. Therefore, the regular calibration of the safety valve is very important for the safety of the entire unit.


After long-term use, the oil quality of the lubricating oil will deteriorate, and the impurities and moisture inside the oil will increase. Therefore, it is necessary to observe and inspect the oil quality regularly. Once the problem is found, it should be replaced in time, and the replacement lubricant grade must comply with the technical data.


The above is the related content of the maintenance of the water-cooled screw chiller introduced by Xiaobian. Although everyone is not so familiar with screw-type chillers, if everyone can understand the maintenance of screw chillers in advance, it is still relatively good. Therefore, I hope that the introduction of Xiaobian will help everyone.
