AI Technical Summary
Existing centrifugal water pumps require manual vacuuming before startup, resulting in poor real-time performance, high labor intensity, and low level of intelligence, making it difficult to meet the requirements of high efficiency, energy saving, and intelligent management in modern water supply systems.
An intelligent vacuum control system was designed, comprising a water outlet pipe, a vacuum system, automatic valves, a vacuum pressure sensor, and a flow sensor. The automatic valves enable unmanned operation of the vacuum circuit, and the real-time monitoring by the vacuum pressure sensor and the flow sensor ensures the automated completion of the vacuuming process.
It has achieved automation and precision in the vacuuming process, reduced manual intervention, improved efficiency and accuracy, reduced labor intensity, and enhanced the intelligence of the water supply system.
