Reasons for Oil Leakage in the Reducer of the Wire Rope Electric Hoist Crane

Seal Damage or Wear:

Over time, seals within the reducer may wear out, allowing oil to leak out.

Improper installation or damage during operation can also compromise the integrity of the seals.

Cracks or Fractures:

Cracks or fractures in the reducer housing or other components can provide pathways for oil to escape.

These cracks may result from fatigue, stress, or manufacturing defects.

Overfilling or Underfilling of Oil:

Overfilling the reducer with oil can cause excessive pressure, leading to leaks.

Conversely, underfilling can result in insufficient lubrication and accelerated wear, potentially leading to leaks.

Improper Maintenance:

Lack of regular maintenance or inspections can allow leaks to go undetected and uncorrected.

Improper cleaning or handling of reducer components during maintenance can also contribute to leaks.

Operating Conditions:

Extreme operating conditions, such as high temperatures or vibrations, can stress the reducer and seals, leading to leaks.

Contamination from dirt, debris, or other foreign materials can also damage seals and cause leaks.

Treatment Methods for Oil Leakage in the Reducer

Inspection and Repair of Seals:

Regularly inspect seals for wear, damage, or misalignment.

Replace worn or damaged seals promptly.

Ensure proper installation and alignment of new seals.

Inspection of Reducer Housing and Components:

Visually inspect the reducer housing and other components for cracks or fractures.

Use non-destructive testing methods, such as ultrasonic testing or magnetic particle inspection, to detect hidden cracks.

Repair or replace damaged components as necessary.

Proper Oil Level Management:

Regularly check the oil level in the reducer and adjust as needed to maintain the recommended operating range.

Avoid overfilling or underfilling the reducer.

Regular Maintenance and Inspections:

Establish a regular maintenance schedule for the wire rope electric hoist crane, including inspections of the reducer and other critical components.

Follow manufacturer recommendations for maintenance procedures and intervals.

Operating Condition Management:

Monitor operating conditions, such as temperature and vibration levels, to ensure they remain within acceptable ranges.

Take steps to mitigate extreme conditions, such as using cooling systems or vibration isolators.

Keep the reducer and surrounding areas clean and free of contamination.
