A typical high-rise residential building in Qingdao built in 2006 faces multiple water supply problems due to insufficient early planning and aging equipment:
Equipment performance decline: Traditional pumping units are inefficient, unit energy consumption is rising, and water pressure fluctuations during peak hours make it difficult for high-rise residents to use water;
Noise pollution disturbs residents: The pump room is noisy during operation, affecting the quality of life of residents;
Operation and maintenance management lags behind: Mechanical failures occur frequently, “leakage” is serious, and there is a lack of data remote monitoring capabilities.
Kaiquan Solution
Kaiquan deploys efficient and silent G2 digital integrated full-frequency water supply equipment with the concept of “full life cycle energy efficiency management” to build a smart water supply ecosystem and perfectly solve customer pain points. The advantages of its solution are as follows:
01 Intelligent permanent magnet is more efficient in all working conditions: equipped with IE5+ ultra-high efficiency permanent magnet motor, it reduces energy consumption by 5% compared with traditional IE3 motors and passes CQC 3153 first-level energy efficiency certification;
02 Motor frequency conversion is highly adaptable and quieter: integrated inverter-motor system optimization algorithm, dynamically adjusts carrier frequency and cooling air volume, and achieves equipment noise reduction of 10~15dB compared with the original system;
03 Fully redundant control system is more reliable: control power supply, PLC, inverter, human-machine interface and pressure transmitter units adopt redundant hot standby redundant technology, and the control system is more reliable;
04 Multi-parameter water pump scheduling is more energy-saving: integrating flow-frequency-power three-parameter collaborative analysis, intelligently switching equipment sleep/pump mode, achieving efficient matching of water pumps and low-consumption operation of equipment.
05 Constant pressure control is energy-saving and comfortable: According to the amount of water used and the impedance characteristics of the water supply network, the pressure compensation is automatically calculated, and the equipment supplies water with variable current and pressure, so as to achieve constant pressure water discharge at the end of the user, which is energy-saving and comfortable.
06 High-protection cable quick connection is more convenient: The control cabinet and intelligent permanent magnet variable frequency pump group are mechatronic design, and the equipment is prefabricated with cables when it leaves the factory; the power cable and signal cable are designed with high-protection connectors, which are reliable in connection and convenient for maintenance and operation.
Solution application results
The implementation of this solution has significantly improved the efficiency and reliability of the water supply system, greatly reduced energy consumption and noise pollution, and improved the quality of life of residents. At the same time, its intelligent operation and maintenance management and fully redundant control system also ensure the long-term stable operation of the equipment and reduce maintenance costs and time.
In the future, Kaiquan will continue to be committed to promoting the advancement of water supply technology and providing more users with efficient, energy-saving and environmentally friendly water supply solutions.
