Common Causes of Automatic Oil Leaks in Oil Purifiers

Oil purifier leaks are often caused by the following:

Poor sealing: Worn, deformed, or damaged seals, as well as gasket failure, can compromise the sealing integrity of the oil purifier, leading to leakage. This is one of the most common causes of automatic oil leaks.

Clogged filter element: 

A filter clogged with oil or impurities can restrict proper oil flow. Under high-pressure or high-flow conditions, oil may escape from the housing, causing leaks.

Improper operation: 

Improper installation or removal, or the use of inappropriate tools, can damage the filter, causing deformation or wear of the housing, ultimately leading to oil leaks.

Aging or wearing components: 

Over time, components such as bearings and seals degrade and lose their effectiveness, causing oil leaks.

Excessive oil level: Overfilling the oil purifier can cause leaks. For example, excess oil in a vacuum pump can leak through the inner hole of the bearing end cap.

Faulty exhaust filter: In an oil filtration system equipped with a vacuum pump, a faulty exhaust filter may not separate oil and air, causing oil to escape from the exhaust port.

Clogged Oil Mist Separator

If the oil mist separator is clogged, filtered oil will not be able to return to the oil reservoir and may accumulate at the exhaust port. During operation, the vacuum pump may expel this oil, causing leaks.

Other Faults

Other issues, such as hardened shaft seals, leaking seal kits, and deterioration/cracks in the oil level sight glass and reservoir gasket, can also cause automatic oil leaks.

Oil Purifier Leakage Solutions

To prevent and resolve oil leaks, consider the following steps:

Inspecting and Replacing Seals

Regularly inspect the condition of all seals and gaskets. ｒｅｐｌａｃｅ any aged or damaged seals and ensure proper installation to maintain sealing performance.

Cleaning or Replacing Filter Elements

Clean the filter elements regularly. If the filter element remains clogged or inefficient after cleaning, install a new one.

Adjusting the Oil Level

Confirm that the oil level is within the recommended range. Drain any excess oil if necessary.

Repairing or Replacing Vacuum Pump Components

For systems with an integrated vacuum pump, inspect the pump regularly. Repair or ｒｅｐｌａｃｅ worn components to ensure proper sealing and operation.

ｒｅｐｌａｃｅ the exhaust filter.

Inspect the exhaust filter regularly and ｒｅｐｌａｃｅ any faulty parts to ensure effective oil and gas separation.

Clean the oil mist separator.

Clean the oil mist separator regularly to prevent clogging. ｒｅｐｌａｃｅ it if severely damaged.

Enhance routine maintenance.

Develop a consistent maintenance schedule that includes cleaning the filter element, replacing wear parts, and inspecting the electrical system. Develop a clear troubleshooting plan to quickly identify and resolve problems.

Final tip: Regular maintenance of the oil purifier and timely replacement of faulty parts are key to preventing oil leaks and ensuring the efficient operation of the oil filtration system.
