As a key equipment in the sewage treatment process, the screw sludge dewatering device can effectively reduce the volume of sludge and lower subsequent treatment costs. However, the device may also encounter some common malfunctions during operation. This article will introduce these faults and their solutions.

Fault 1: Decreased dehydration effect

Reason analysis: The decrease in dewatering effect may be due to filter clogging, screw shaft wear, or changes in sludge properties.

Solution: Regularly clean the filter screen to remove blockages. Check the wear of the spiral shaft and replace it in a timely manner. Adjust the sludge pretreatment process to adapt to changes in sludge properties.

Fault 2: Excessive noise during equipment operation

Cause analysis: Excessive noise may be due to bearing damage, improper clearance between the spiral shaft and the bearing seat, or loose fasteners.

Solution: Check and replace damaged bearings. Adjust the gap between the spiral shaft and the bearing seat to ensure it is within a reasonable range. Check and tighten all loose fasteners.

Fault 3: Motor overheating

Cause analysis: Motor overheating may be due to overload operation, poor heat dissipation, or motor malfunction.

Solution: Avoid prolonged overload operation of the device. Clean the motor cooling system to ensure smooth heat dissipation. For problems with the motor itself, professional inspection and replacement should be carried out.

Fault 4: Equipment oil leakage

Cause analysis: Oil leakage may be due to damaged seals, aging oil seals, or improper installation.

Solution: Check and replace damaged seals and oil seals. Ensure that the seals and oil seals are installed correctly to avoid oil leakage.

Fault 5: The spiral shaft does not rotate flexibly

Reason analysis: The inflexibility of the spiral shaft rotation may be due to lack of lubrication, bearing damage, or shaft bending.

Solution: Regularly lubricate the spiral shaft to reduce friction. Check the bearings and replace damaged components in a timely manner. For bent shafts, calibration or replacement should be carried out.

epilogue

The stable operation of the screw sludge dewatering machine is crucial for the normal operation of sewage treatment plants. Through regular maintenance and inspection, faults can be prevented and resolved in a timely manner, ensuring efficient operation of the equipment. Quickly and accurately diagnosing problems and taking corresponding solutions when facing faults is the key to ensuring long-term stable operation of equipment.
