Characteristics of variable frequency constant pressure water supply system
Characteristics of variable frequency constant pressure water supply system
1. Power saving: The most obvious advantage of variable frequency constant pressure water supply system is to save electricity, and the energy saving is usually 10-40%. From the perspective of energy conservation of a single water pump, the smaller the flow, the greater the energy conservation. The optimized energy-saving control software enables the water pump to achieve maximum energy-saving operation;
2. Sanitary and water-saving: set the pipe network pressure according to the actual water use situation, automatically control the water output of the pump, and reduce water leakage; After the closed loop water supply is implemented in the system, all the water for users is directly supplied by the pipeline. The water tower, roof pool, air pressure tank and other facilities are cancelled to avoid the "secondary pollution" of water and to cancel the regular cleaning of the pool.
3. Reliable operation: The variable frequency constant pressure water supply system realizes the stable water supply pressure of the system and the continuous change of the flow in a large range, so as to ensure the water pressure of the user at any time. It will not occur that the water heater cannot be used normally during the peak water use period. The frequency converter will realize the soft start of the pump, so that the pump can realize the impact free switch from power frequency to variable frequency, to prevent the impact of the pipe network, the pipe network pressure exceeding the limit, and the pipe rupture.
4. Flexible control: sectional water supply, regular water supply, manual selection of working mode.
5. Perfect self-protection function: the new variable frequency and constant pressure water supply system in the community has over-current, over-voltage, undervoltage, under phase, short circuit protection, instantaneous power failure protection, overload, stall protection, etc
