Sell second-hand 650 type horizontal screw centrifugeDuring the use of the decanter centrifuge, material blockage often occurs. Below, I will share with you the troubleshooting methods I know:

In the case where the auxiliary frequency converter alarm overload cannot be turned on normally in the horizontal centrifuge, we can remove the protective cover of the auxiliary motor and manually rotate the input shaft pulley of the differential several times. If there is a jamming phenomenon, it proves that there is too much material stuck between the screw and the drum. The solution is as follows

1. Use something to clamp the differential pulley and manually rotate the steering wheel along the drum until the resistance is clearly felt to disappear. Then adjust the main and auxiliary equipment to a lower frequency, start at low speed, and rinse with water

2. Some centrifuge machines use foreign frequency converters such as ABB. AB 。 Siemens Wait, some frequency converters have specialized low-speed protection startup methods.

If it can achieve low-speed high torque starting function. So just adjust the main and auxiliary engines to the low-speed range and rinse them with water.

3. Another method is to hold the drum still, remove the water blocking adjustment plate at the end of the drum, and set the auxiliary machine to reverse to allow the material to be discharged from the drum's drainage outlet

Adjust the auxiliary machine to forward rotation and repeat the discharge operation. This method is suitable for large aspect ratio horizontal screw machines with severe material blockage that cannot be manually coiled
