Pipeline Cleaning Requirements of Screw Chiller System

图片
  If the chiller is used for too long, some impurities will inevitably exist inside, which will affect the refrigeration system. In order to ensure the stable cooling effect of the chiller and prolong the service life of the chiller, regular maintenance of the chiller is required. So, what are the requirements for pipe cleaning of   screw chiller system ? Observe that the oil color of the compressor refrigerating oil of the screw chiller turns brown, indicating that the oil has been turbid, check whether the smell has a burnt smell, and check the resistance value of the motor winding in the compressor. If the resistance between the windings and the casing is normal and well insulated, the refrigerating oil and cleaning system must be replaced. For the contamination in the system pipeline, the cleaning agent can be used to clean it. Before cleaning, first discharge the refrigerant in the refrigeration system, then remove the compressor, and pour the refrigerant oil from the process tube

Precautions and Maintenance Methods for Air-Cooled Screw Chillers

  1. In order not to affect the cooling effect of the   air-cooled screw chiller , to ensure the normal and continuous operation of the plastic equipment. Please place the chiller in a clean, well-ventilated place with good heat dissipation (it is recommended to place it outdoors with a sunshade, and there is no large heat source in the space within 2M of the equipment). 2. Please clean the condenser regularly. It is best to use gas of no less than 0.8Mpa (usual nitrogen) or a soft brush to clean the dust on the condenser fins (blow perpendicular to the fins to prevent the fins from blowing Inverted), in order to avoid the poor heat dissipation of the condenser during long-term operation of the equipment, resulting in high-pressure protection of the chiller, and the compressor does not start, which may affect customer use. 3. Please remind customers to clean the water tank regularly and change the water frequently. Generally, the pure water is replaced once a month, and the water tank

Which Industries Are the Chillers Used in?

  With the development of the refrigeration industry, the application of chiller refrigeration technology has become increasingly widespread. Water chillers  are widely used in plastic injection and blow molding, metal processing cutting oil, welding equipment, die casting and machining, chemical processing, pharmaceuticals, industrial processing equipment, food, and beverage processing, paper-making, cement processing, vacuum systems, X-ray diffraction, analysis equipment, semiconductors, compressed air and gas cooling, etc. 1. Clothing inventory chiller: processing clothing, clothing production, and workshop cooling, initial cooling of service processing equipment, clothing inventory, and other series of cooling control the temperature, humidity, and cleanliness of the environment to varying degrees. 2. Food ice water machine engineering Perishable food must maintain a stable low-temperature environment during the entire circulation process from purchasing or fishing, processing, sto
