Introduction to Technical Performance of Horizontal Spiral Centrifuge in Pharmaceutical Factory

The control cabinet is equipped with built-in electrical appliances to control the main and auxiliary motor frequency converters, enabling simple operation. When a fault occurs in the system, corresponding alarms are triggered and fault information is displayed, making it easy to operate and maintain.

The differential speed between the drum and the screw is controlled by an automatic differential and torque control system:

○ Differential automatic control: The stability of the differential ensures the stability of the spiral feeding speed

Differential speed reflects the speed of the centrifugal screw pushing material. Materials with large differential speed have a short residence time in the drum, insufficient dehydration, high moisture content in the cake, but can increase processing capacity; On the contrary, small differential speed results in low moisture content of the cake and small processing capacity; The use of constant differential speed control can keep the spiral feeding rate stable at all times.

Spiral feeding torque constant torque control: adjust differential speed to achieve stable feeding torque

The torque of the spiral feeding reflects the load situation of the centrifuge. Excessive torque can easily cause blockage of the centrifuge, and in severe cases, damage to the differential. Insufficient torque can easily result in unsatisfactory separation effect; The use of constant torque control can keep the screw pushing torque stable at all times, reducing the accumulation of material in the drum and avoiding material blockage.

The differential speed between the drum and the screw is controlled by an automatic differential and torque control system:
