What Are The Common Faults Of Pneumatic Lubricators And How To Maintain Them?

Pneumatic lubricators are a tool widely used for lubrication of mechanical equipment. They use air pressure to deliver lubricating oil to key parts of the equipment to ensure the normal operation of the equipment. However, during long-term use, pneumatic lubricators may have various faults that affect the lubrication effect of the equipment. This article will introduce the common faults of pneumatic lubricators and their maintenance methods to help users extend the service life of the equipment and improve work efficiency.

1. Common faults and their causes

Insufficient pressure or failure to discharge oil

Possible causes:

The air source pressure is too low or unstable.

The oil pipe is blocked or leaking.

The oil tank is insufficient or the oil viscosity is too high.

Solution:

Check and adjust the air source pressure to meet the equipment requirements.

Check whether the oil pipe is blocked or damaged, and clean or replace it in time.

Make sure there is enough lubricating oil in the oil tank and use lubricating oil that meets the standards.

Unstable oil injection volume

Possible causes:

The nozzle or valve is blocked.

The air pressure fluctuates greatly.

The internal seal of the lubricator is aging or damaged.

Solution:

Clean or replace the blocked oil nozzle and valve.

Use a stable air source to avoid air pressure fluctuations affecting oil supply.

Check whether the seal is intact. If there is aging, replace it in time.

Air pressure oiler leaks

Possible reasons:

Loose connection parts or damaged seal rings.

The sealing performance of the oil pump or control valve has decreased.

Solution:

Tighten all connecting parts to ensure good sealing at the interface.

Replace damaged seal rings to ensure good sealing.

The oiler is too noisy

Possible reasons:

Internal air enters the oil circuit, resulting in poor oil supply.

The mechanical parts inside the equipment are worn and unstable in operation.

Solution:

Exclude air from the system to ensure smooth oil circuit.

Check the wear of internal parts of the equipment regularly and replace damaged parts.

2. Daily maintenance and care

Check the oil volume regularly

Ensure that there is always enough lubricating oil in the oil tank to avoid equipment damage due to lack of oil.

Select suitable lubricating oil to avoid excessive oil viscosity or excessive impurities affecting the oil supply effect.

Clean the oil system

Clean the oil pipes, nozzles and filters regularly to prevent oil blockage.

Replace the filter regularly to prevent impurities from entering the oil injection system.

Check the seals

Observe whether there is oil or air leakage at the connection of the equipment. If any problems are found, the seals should be replaced in time.

Keep the gas source stable

Use a stable gas source to ensure that the air pressure is within the normal range to avoid the oil supply effect affected by air pressure fluctuations.

Regularly inspect the oiler

Set a regular maintenance plan, check the operating status of the oiler, and deal with abnormalities in time to prevent the expansion of faults.

Summary

The pneumatic oiler plays an important role in mechanical lubrication, but during long-term use, problems such as insufficient pressure, unstable oil injection, air leakage and excessive noise may occur. By regularly checking the oil volume, cleaning the oil circuit, maintaining the seals, and ensuring the stability of the gas source, the occurrence of faults can be effectively reduced and the service life and work efficiency of the equipment can be improved. Reasonable maintenance can not only reduce maintenance costs, but also ensure the continuous and efficient operation of the equipment.
