Shanghai Songjiang Vibration Absorber Co.,Ltd. Official Website presents: Information on PVC rubber joints for the cooling water circulation system of the Michelin Quad Line in the United States. Songjiang Group provides vibration damping and noise reduction systems for numerous industrial enterprises. Below is the introduction of PVC rubber joints for the cooling water circulation system of the Quad Line.
1.Introduction to Cooling Water Circulation Systems:
Cooling water circulation systems are crucial components used in industrial and commercial facilities to remove heat and maintain equipment temperature. These systems can be classified into two types based on their design and operation: open and closed systems.
Open Cooling Water Circulation System:
Open systems use air and water contact to lower the water temperature, typically involving cooling towers or cooling ponds. The design and operation of open systems are relatively complex, with the following main features:
Cooling Equipment: Includes cooling ponds and cooling towers. Cooling towers often use fans to promote evaporation, further lowering water temperature.
Evaporation and Make-up Water: Due to evaporation and wind losses, the system needs a constant supply of fresh water to maintain water balance. These processes lead to the concentration of minerals and salts in the water, necessitating periodic discharge of some circulating water (known as blowdown water) to prevent scaling.
Water Quality Treatment: Since water flow contacts the atmosphere, dust, microorganisms, and other contaminants enter the circulating water. Additionally, the loss of carbon dioxide and leakage of materials in heat exchange equipment alter water quality. Therefore, open systems often require treatment of circulating water, mainly including sediment control, corrosion control, and microbial control. These treatment methods depend on the quantity and quality of make-up water and the performance of production equipment.
Closed Cooling Water Circulation System:
Closed systems use enclosed cooling equipment, with water circulating through pipes, typically cooled by external air. Closed systems are relatively simple, with the following main features:
Cooling Equipment: Circulating water flows through enclosed pipes, with external air used to dissipate heat and lower temperature.
Stable Water Quality: Since water flow does not contact the atmosphere, water quality remains unchanged except for material leakage in heat exchange equipment. To prevent scaling, cooling water may need to be softened.
Corrosion Prevention: To prevent corrosion of heat exchange equipment, corrosion inhibitors are often added. If using high-concentration or highly toxic corrosion inhibitors, safety precautions are necessary, and cooling water discharged during maintenance should be properly handled.
