Description :

　　Functional characteristics of non negative pressure variable frequency water supply equipment

　　1. Save electricity, reduce footprint, and save more than 30% energy compared to general water supply equipment. This equipment has a small footprint, simple structure, and shortened construction period.

　　2. Quality intelligent computer control, specially developed independently, with diverse functions to provide precise control at a high level. Extended reading: Reference table for selection of variable frequency constant pressure water supply equipment

　　3. The energy-saving system can automatically adjust the speed of the water pump and the number of running water pumps according to the required water consumption, greatly saving electricity and increasing the service life of the water pump.

　　4. Maintaining a constant pressure, the outlet pressure can remain stable under drastic changes in water usage, providing users with a comfortable water environment.

　　Working principle and application fields of variable frequency constant pressure water supply equipment

　　1. Variable frequency water supply equipment is connected to the municipal pipeline network for constant pressure water supply. When the water supply pressure can meet the needs, all pumps will be automatically shut down. Otherwise, the constant pressure water supply equipment will start and increase the pressure to meet the water requirements.

　　2. Additional small pumps or pressure tanks can be added to completely eliminate the power consumption of low flow or zero flow water supply. When the water supply pressure is low, the main pump will automatically stop and the small pump or pressure tank will operate.

　　3. Customized variable frequency constant pressure water supply equipment can be consulted with Duko Pump Industry. Simultaneously providing water pump maintenance and upkeep.

　　Principle of Water Supply Scheme for Variable Frequency Constant Pressure Water Supply Equipment

　　1. The main function of variable frequency constant pressure water supply is preset, and the frequency should be based on the rated frequency of the motor as the working frequency of the frequency converter.

　　2. When using a PID controller, the acceleration and deceleration times should be set as short as possible to avoid affecting the dynamic response process determined by the PID controller.

　　3. If the frequency converter itself has PID regulation function, as long as the PID function is set to be effective during the preset;
