The cooling effect of industrial chiller depends on its quality. However, industrial water chillers will always have wear and aging in the process of use, so it is necessary to regularly maintain and analyze the record of its operating parameters, listen to the sound emitted during operation, check the use of snow, refrigeration oil, etc., and regularly do maintenance and other operations for it. Industrial chiller routine maintenance can be considered from the following 5 points:
1, regular cleaning of the condenser and evaporator
Condenser / evaporator is the second most important component of the industrial chiller, ** is half a year to clean. Water-cooled condenser cooling water is an open loop, using tap water is recycled through the cooling water tower, easy to decompose and deposit impurities on the water pipe to form scale, affecting the heat transfer effect. Thick scaling will also make the cooling water flow cross-section narrowing, water reduction, condensing pressure rise. Therefore, when the use of tap water quality is poor, ** is cleaned at least once a year to remove the scale in the tube, ** the tap water for water treatment operations.
2, regular checks on the compressor
Compressor is the chiller’s “heart”, its good or bad directly affects the stability of the chiller when used. If the compressor fails to repair, the cost is relatively high, especially the screw compressor precision high price. Therefore, if you hear the compressor has an abnormal sound or other conditions, ** to contact the chiller manufacturer to find a professional engineer to overhaul, find out where the cause is and maintenance treatment.
3, regular testing of the safety valve
Industrial chiller condenser and evaporator are pressure vessels, according to the provisions of the high-pressure end of the chiller that is, the condenser body on the installation of safety valves, once the unit is in a non-normal working environment, the safety valve can be automatically relieved to prevent high-pressure may be harmful to the human body.
4、Regular replacement of filter drier
Filter drier is an important part to ensure the normal circulation of refrigerant. As water and refrigerant are immiscible, if the system contains water, will greatly affect the operating efficiency of the chiller, so keep the system dry inside is ** important, filter drier inside the filter element must be replaced regularly.
5, regular replacement of lubricating oil
Industrial chiller after long-term use, the oil quality of the lubricating oil will deteriorate, the impurities within the oil and moisture increase, so we must regularly observe and check the oil quality. Once the problem is found should be replaced in a timely manner, the replacement of the lubricant brand ** to the original manufacturer shall prevail.
For the maintenance of industrial chiller is shared here, industrial chiller is widely used in plastics, electroplating, electronics, chemicals, pharmaceuticals, printing, food processing and other industrial refrigeration process requires the use of chilled water in the field, or can also be villas, restaurants, hotels, institutions, schools, factories and other human activities in the field of space to provide comfort air conditioning.
