The low-pressure water pump motor frequency conversion speed regulation device has the following characteristics:
(1) The motor has achieved a soft start, the starting current is limited to the rated current of the motor, the starting process is very stable, and the impact on the grid is reduced; the protection function is complete;
(2) It can enhance the safety of personnel and equipment; eliminate mechanical vibration, extend the service life of equipment, and save a lot of maintenance costs;
(3) Implement precise control and improve the level of process control; reduce energy consumption and save operating costs;
(4) With torque compensation function, the V/f mode voltage can be automatically increased according to the load condition to ensure the required torque. This value is automatically calculated by the inverter to ensure reliable operation and energy-saving effects;
(5) Communicate with the computer control system to realize remote control and real-time monitoring.
The use of frequency conversion speed regulation can solve the problem of difficult control. Using conventional adjustment methods such as PID or limiter control, the system pressure and flow can be adjusted by adjusting the opening of the outlet valve, but the characteristics of the control object are complex and cannot be well controlled. Achieve the effects of improving the process, reducing maintenance, reducing work intensity, and energy savinga
