Product Description
The non-negative pressure water supply equipment uses PLC and PID frequency conversion control technology and consists of a steady flow tank and constant pressure frequency conversion water supply equipment. The equipment is directly connected in series with the municipal tap water network pipe. The outlet pressure is detected through a pressure transmitter, and the detection value and set value are After comparison, the PLC calculates the pressure value that needs to be increased based on the original pressure of the municipal tap water network pipe to determine the number of water pumps put into operation and the frequency converter drive output frequency to achieve constant outlet pressure.
Performance and advantages
The non-negative pressure water supply equipment can directly introduce water from the city's tap water pipe network into high-rise residences. The intermediate process does not require low-level pools and high-level water tanks, that is, purified water flows directly into households. Non-negative pressure water supply If the non-negative pressure water supply equipment is used in conjunction with fire-fighting air pressure tanks, and on the premise of complying with fire protection regulations, the low-level pool and high-level water tank will be gradually eliminated, which not only saves cleaning and disinfection costs, but also has obvious power and energy savings. water effect.
