The heat exchange station is an important link connecting the heating company and the user, and its work safety and reliability directly affect the user’s heating quality. The automatic control system of the heat exchange station can realize remote monitoring of pressure, temperature and flow data of the primary and secondary networks; The operating status of circulating pump and make-up pump; Real-time information such as the liquid level of the replenishment tank and the opening of the regulating valve, and the heat exchange process can be effectively controlled.

During actual use, the make-up pump starts and stops through the return pressure control; The circulating pump runs with variable frequency, and the frequency is adjusted by the pressure difference between supply and return water; The condensate pump runs through the condensate tank level. Make-up pump control principle: through the return pressure transmitter to transmit the current signal to the PLC, through the calculation, the feedback value is compared with the set value, when the pressure reaches the set lower limit value, the PLC gives a signal to automatically start the replenishment pump; When the pressure reaches the set upper limit, the PLC gives a signal to automatically stop the replenishment pump; At the same time, when the water level of the make-up water tank is lower than the protection value, the make-up pump is forced to stop the pump.

As a manufacturer of pressure transmitters, Xingyi has established a good cooperation and return visit system with tens of thousands of users. The CYYZ08 pressure transmitter is a pressure transmitter for constant pressure water supply and heat exchange station type developed by visiting and analyzing with many users. Xingyi CYYZ08 pressure transmitter has the basic technical parameters and performance of pressure transmitter for heat exchange station, and has high cost performance.

Xingyi’s engineers also summarized the following points for users to use pressure transmitters in heat exchange stations:

First, the pressure transmitter is installed without pressure and without power supply.

2. When the pressure transmitter is connected with the heat exchange pipeline, it is usually connected with the external thread of M20*1.5. If there is a special connection method, Xingyi supports the customized needs of the product.

3. Use of pressure transmitter in heat exchange station If the medium temperature exceeds the working temperature range of the pressure transmitter, a cooling device can be installed for the pressure transmitter. Extend the 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 the pressure intake from being blocked and affecting the measurement accuracy.

5. When disassembling the pressure transmitter, it is necessary to ensure the disconnection of the pressure source and the power supply to avoid the accident of medium spraying.
