(1) The high-voltage inverter excellent soft start / stop function (can start at zero speed), the maximum current during startup is less than the rated current, greatly reducing the impact of starting inrush current on the motor grid, effectively reducing the motor failure and thus Greatly extending the service life of the motor overhaul cycle, but also can effectively avoid the impact of negative impact on the power grid;
(2) After frequency transformation, the original throttle is fully open, greatly reducing its wear and tear, prolonging the service life of the damper, and reducing maintenance and repair costs;
(3) After frequency transformation, the original hydraulic coupler is canceled, which saves the maintenance cost of the hydraulic coupler;
(4) The unique smooth adjustment of the high-voltage inverter reduces the mechanical wear of the fan and the motor, and at the same time, reduces the temperature of the bearing and the bearing bush, effectively reduces the maintenance cost and prolongs the service life of the equipment.
(5) to facilitate the realization of dust control system automation. The air volume of the dust removal system often needs to be changed according to the requirements of the process. In the past, when the damper was adjusted, it was often difficult to precisely control the air volume due to the wear of the actuator and the change of the valve characteristics. The frequency control method is always maintained high-precision adjustment (0.1 ~ 0.01Hz), in order to achieve dust control system automation provides superior conditions.
