Causes of Oil Leakage in Powder Tablet Presses and Effective Solutions

Powder tablet presses are widely used in laboratory and industrial applications. As essential molding equipment, their operational stability and sealing performance directly affect production efficiency and product quality.

However, oil leakage is a common issue during operation. It not only disrupts normal equipment performance but may also lead to reduced efficiency and potential quality risks. Understanding the causes and solutions is therefore critical.

Common Causes of Oil Leakage

1. Seal Aging or Damage

Seals are key components that prevent oil leakage within the hydraulic system.
Over time, exposure to high temperature, pressure, and friction reduces their elasticity, leading to cracks or deformation and ultimately causing leakage.

2. Equipment Vibration and Loose Connections

During operation, continuous vibration may loosen bolts, joints, and connectors.
This can weaken sealing performance in the oil circuit and result in leakage.

3. Unreasonable Oil Circuit Design

Some tablet presses have design limitations, such as:
Excessive oil pipeline joints
Insufficient machining accuracy

These issues increase the risk of leakage at connection points.

4. Oil Tank or Pipeline Damage

Long-term use or external impact may cause cracks in the oil tank or pipelines, especially under high-pressure conditions, leading to oil leakage.

5. Improper Lubricant Selection or Management

Using unsuitable lubricating oil or failing to replace it regularly can lead to oil deterioration.
This accelerates seal wear and increases the likelihood of leakage.

Effective Solutions

1. Regular Seal Inspection and Replacement

Inspect seals periodically and replace them when necessary.
Use high-quality materials with strong resistance to heat and wear.

2. Tightening and Reinforcing Connections

Check bolts and joints regularly to ensure they are secure.
Apply anti-loosening measures such as locking adhesives or washers when needed.

3. Optimize Oil Circuit Design

For design-related issues, consult the manufacturer for improvements.
Reducing joint numbers and enhancing machining precision can significantly lower leakage risks.

4. Repair or Replace Damaged Components

Minor cracks in tanks or pipelines can be repaired through welding or sealing compounds.
Severely damaged components should be replaced promptly.

5. Proper Lubricant Management

Select lubricants according to equipment requirements.
Replace oil regularly to maintain performance and prevent internal wear.

Preventive Measures

Preventive maintenance is essential to minimize oil leakage risks:

Establish a routine maintenance schedule, including seal checks and oil circuit cleaning
Operate equipment strictly according to guidelines to avoid overpressure
Maintain a suitable working environment, avoiding high temperature, humidity, or corrosive conditions
Provide professional training for operators to improve fault detection and handling

Conclusión

Oil leakage in powder tablet presses is a common but manageable issue.
Through regular maintenance, proper operation, and timely repairs, its occurrence can be effectively reduced.

Users should prioritize daily inspection and preventive measures to ensure stable operation and long-term efficiency.
If leakage occurs, contacting the supplier or professional technicians promptly is recommended to avoid production delays and additional losses.
