Decanter centrifuges often have some common faults, which are generally manifested as difficult startup and strong vibration during idle operation. The following is a summary of the troubleshooting problems for the decanter centrifuge machine:
The starting current of the centrifugal dehydrator is large and the time is long, which leads to the maintenance posture of the electrical switch;
There are too many stored materials in the drum storage device, which causes the screw to be blocked;
The air pressure is too low, or the pressure controller is not working properly.
During the maintenance and installation process, the drum scale is not aligned at both ends, which harms the precision of rotor dynamic balance;
The lubricating grease has deteriorated;
The bearings are invalid;
The inner hole of the main bearing is loosened with the shaft;
The common fault of the helical conveyor bearing;
The foot bolts of the ash discharge port are not tightened or the rigid connection of the pipe is not good;
The engine flange plate is loose, causing the differential to vibrate;
The differential is damaged (usually due to lack of oil);
After stopping the gas, the feeding gate valve is not tightly closed, causing material leakage in the drum and causing bias;
Loosening and deformation occur at the joint of the rotating parts;
The rotor dynamic balance of the newly replaced components is poor;
Serious damage to relevant components;
Raw materials deposited inside the shell rub against the outer drum.
The V-belt and drum (especially the main roller shaft) roll under the influence of oil stains, causing waste of frictional kinetic energy;
Common faults of the differential (usually caused by lack of oil), when the differential housing sub-pulley and the keyed shaft are burned.
The oil is affected and loses lubrication;
The bearing is damaged or the clearance is too small;
The transmission belt is too tight, which enlarges the frictional output power of the main bearing and heats up;
Insufficient oil supply or engine flameout.
Insufficient diesel fuel in the differential;
Heavy load burden;
Differences in heat dissipation;
The differential bearings or components are damaged;
The suspension solid concentration value is too low or too little is added;
The proportion of solid and liquid is too close;
The rotation direction of the device is reversed;
The differential is damaged;
The discharge port of the drum blocked by blockage or internal raw material accumulation;
The deposition of raw materials between the shell and the drum.
