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.
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.
1. The requirement is stable and reliable, and it can run without interruption for a long time.
2. A continuous adjustment is required to adjust the temperature and flow in time and accurately.
3, it is required that the number of tables can be automatically adjusted according to the demand of the process flow.
The pump frequency controller is to provide advanced products crystal electric control and transmission professional combination, to meet the long-term stable and reliable operation of water system requirements; built-in enhanced PID regulator, can meet any continuous process control, which can be used to adjust the pressure, can also be used to adjust the temperature; single pump operation, integrated solutions the multi pump on-line control, switching frequency, can be fully realized from the most simple maintenance free online to high-end built-in switching device, no external control unit such as PLC, which greatly improves the system reliability.
