Case details

Recirculating cooling water system is one of the most common processes in industry. It is a cooling water system that uses water as cooling medium and circulated. Its function is to quickly discharge large quantities of heat generated in industrial production. According to statistics, the cooling water accounts for about 70% of the industrial water consumption, so the recirculating cooling water system plays a role of saving a lot of industrial water, and the process is controllable, which is more energy efficient and reliable than the non circulating DC system.

循环冷却水系统主要由换热设备、冷却设备、水泵和管道组成。循环冷却水系统分为敞开式和封闭式两类。循环冷却水系统的传动和工艺控制是结合在一起的:

The circulating cooling water system is mainly composed of heat exchange equipment, cooling equipment, water pump and pipe. The circulating cooling water system is divided into two types: open type and closed type. The transmission and process control of the circulating cooling water system are combined together.
