Five-step stable industrial chiller cooling effect
The chiller is already an indispensable part of the plastics, electronics, chemical, food preservation, ink printing, pharmaceutical, machinery and other industries. Its main function is to provide chilled water to the equipment / products to achieve the purpose of cooling. The cooling effect of an industrial chiller depends on its quality. However, we all know that industrial chillers will always wear out during use. Therefore, we need to record and analyze its operating parameters regularly, listen to the sounds emitted during operation, check the use of snow and frozen oil, and regularly. Perform maintenance operations for it. The daily maintenance of industrial chillers is very simple. Users are advised to consider the following points:
1. Regularly check the compressor
The compressor is the "heart" of the industrial chiller, and its quality directly affects the stability of the chiller when it is used. If the compressor fails and is repaired, the cost is relatively high, especially the precision of the screw compressor is high and expensive. Therefore, if you hear abnormal sounds or other conditions in the compressor, be sure to find a professional engineer in the chiller factory to check the cause and carry out maintenance.
2. Clean the condenser and evaporator regularly
The condenser/evaporator is the second most important component of an industrial chiller, and it is good to clean it once every six months. The cooling water of the water-cooled condenser is an open circulation loop. The tap water used is recycled through the cooling tower, which easily decomposes and deposits impurities to form scale on the water pipe, which affects the heat transfer effect. 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 tap water used is inferior in water quality, the zui is cleaned at least once a year to remove the scale in the pipe, and the water treatment operation is performed on the tap water.
3. Regular inspection of safety valves
The condenser and evaporator of the industrial chiller belong to the pressure vessel. According to the regulations, the safety valve should be installed on the high pressure end of the chiller, that is, the condenser body. Once the unit is in an abnormal working environment, the safety valve can automatically relieve pressure. To prevent high pressure damage to the human body.
4, regular replacement of lubricants
After long-term use of the industrial chiller, the oil quality of the lubricating oil will deteriorate, and the impurities and moisture inside the oil will increase, so it is necessary to observe and check the oil quality regularly. Once the problem is found, it should be replaced in time. The replacement lubricant brand zui is subject to the original manufacturer's offer.
5. Regularly change the dry filter
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 chiller. Therefore, it is very important to keep the internal drying of the system. The filter element inside the drying filter must be replaced regularly.
