Non negative pressure variable frequency water supply equipment, constant pressure variable frequency water supply equipment, production of secondary water supply equipment manufacturer

Description :

Non negative pressure variable frequency water supply equipmentThe functional characteristics of

　　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.

　　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;

Variable frequency constant pressure water supply equipmentWorking principle and application fields of

　　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.

　　Types and characteristics of variable frequency constant pressure water supply equipment

　　1. Efficient and energy-saving. Compared with traditional water supply methods, variable frequency constant pressure water supply can save energy by 30% -60%.

　　2. Small footprint, low investment, and high efficiency.

　　3. Flexible configuration, high degree of automation, complete functions, flexible and reliable.

　　4. Reasonable operation, due to the decrease in average speed within a day, the average torque and wear on the shaft are reduced, and the service life of the water pump will be greatly improved.

　　5. Due to the ability to achieve soft stop and soft start of the water pump, and the elimination of water hammer effect (water hammer effect: when starting and stopping directly, the kinetic energy of the liquid increases sharply, causing great impact on the pipeline network and having great destructive power).
