Heat exchange stations are an important link connecting heating companies and users, and their work safety and reliability directly affect the quality of heating for users. The automatic control system of the heat exchange station can remotely monitor the pressure, temperature, and flow data of the primary and secondary networks; Operation status of circulating pump and make-up water pump; Real time information such as the liquid level of the make-up water tank and the opening of the regulating valve can effectively control the heat exchange process. During actual use, the make-up pump is controlled to start and stop by the return water pressure; The circulating pump operates with variable frequency, and the frequency is adjusted by the difference in supply and return water pressure; The condensate pump operates through the water level of the condensate water tank. The control principle of the make-up water pump: The current signal is transmitted to the PLC through the return water pressure transmitter. Through calculation, the feedback value is compared with the set value. When the pressure reaches the set lower limit value, the PLC provides a signal to automatically start the make-up water pump; When the pressure reaches the set upper limit value, the PLC sends a signal to automatically stop the make-up water pump; When the water level in the make-up water tank is lower than the protection value, the make-up water pump will be forced to stop. CYYZ08 dedicated pressure transmitter is a constant pressure water supply and heat exchange station type dedicated pressure transmitter developed through practical application and analysis. The CYYZ08 pressure transmitter has the basic technical parameters and performance of a pressure transmitter for heat exchange stations, while also having a high cost-effectiveness. Precautions for using CYYZ08 specialized pressure transmitter in heat exchange stations: 1. The pressure transmitter should be installed without pressure or power supply. 2. When connecting pressure transmitters to heat exchange pipelines, M20 * 1.5 external threads are usually used for connection. If there are special connection methods, Star Instrument supports customized requirements for the product. 3. If the medium temperature exceeds the working temperature range of the pressure transmitter in the heat exchange station, a cooling device can be installed for the pressure transmitter. Extend the service life of pressure transmitters. 4. During on-site installation, a pressure shut-off valve should be installed between the pressure transmitter and the pipeline to facilitate maintenance and prevent blockage of the pressure tap, which may affect measurement accuracy. 5. When disassembling the pressure transmitter, it is necessary to ensure that the pressure source and power supply are disconnected to avoid accidents caused by medium spraying.
