Oil pump oil seal

Oil pump oil seal is a key mechanical seal device, which is widely used in various hydraulic equipment and fuel systems. Its main function is to prevent lubricating oil or hydraulic oil from leaking out of the rotating shaft of the oil pump, and at the same time, it can also prevent external pollutants from entering the oil pump and protect the normal operation of the oil pump. This article will introduce the structure, working principle, common problems and maintenance of oil pump seals.

The structure of the oil seal of the oil pump

The oil seal of the oil pump is generally composed of an outer ring, an inner ring, a sealing gasket, a spring, etc. The outer ring is mounted on the oil pump housing, and the inner ring is fixed on the rotating shaft of the oil pump.

A sealing gasket is embedded on the contact surface between the two rings, which plays a sealing role and can withstand a certain pressure. Springs are used to provide pressure to the gasket so that it can be sealed effectively.

The working principle of oil pump oil seals

The working principle of oil pump oil seals is based on the action of sealing gaskets. When the oil pump rotates, the lubricating oil or hydraulic oil will enter the inside of the outer ring of the oil seal through the oil pump housing, and then enter the inside of the inner ring through the gap of the sealing gasket.

The gap between the inner ring and the rotating shaft is so small that liquid cannot leak out of it. At the same time, the pressure of the spring maintains good contact with the sealing gasket and ensures the sealing effect.

Frequently Asked Questions on Oil Pump Oil Seals

Leakage

Leaking oil seals in oil pumps is a common problem and is usually caused by wear, aging or damage to the gaskets. Leaking oil seals should be replaced in time to prevent fluid waste and mechanical failure.

Pollution

When the sealing performance of the oil seal of the oil pump is reduced or damaged, external contaminants may enter the inside of the oil pump. These contaminants can damage the parts and components of the oil pump, leading to equipment failure. Therefore, it is necessary to check and replace the oil pump oil seal regularly.

Noise

When the oil pump seal is worn or loose, noise may be generated. This noise may interfere with the normal operation of the equipment and is also an indication that the oil seal needs to be repaired or replaced.

Maintenance of oil pump seals

Check it regularly

Regularly check the working status of the oil seal of the oil pump, including whether there is leakage, noise or abnormal vibration, etc. If a problem is found, repair or replacement measures should be taken in time.

Limpieza y mantenimiento

Keep the oil seal of the oil pump clean to prevent external contaminants from entering. Regular cleaning of the oil pump and replacement of lubricating or hydraulic oil can help extend the life of the oil pump seal.

Pay attention to the conditions of use

When using the oil pump, care should be taken to avoid conditions such as excessive temperature, excessive pressure or excessive speed, which may cause damage to the oil seal of the oil pump. Reasonable operation and use can reduce the occurrence of oil seal failure.

To sum up, the oil pump seal is an important mechanical seal device in the hydraulic equipment and fuel system. It prevents lubricating or hydraulic oil from leaking out by sealing gaskets and springs, while also preventing external contaminants from entering the inside of the oil pump.

However, oil pump seals can have problems such as leakage, contamination, and noise, so they need to be regularly inspected, cleaned, maintained, and paid attention to the conditions of use to ensure that they work properly and prolong their service life.
