The Importance of Lubricant Sealing for Compressor Bearings

Compressor bearings are a critical component in compressors, responsible for supporting and balancing the movement of the rotor and Withstand tremendous pressure and impact from the compressor. In order to ensure that bearings can operate normally, reduce friction and heat, and improve operating efficiency, lubricating oil plays a key role.

Lubricating oil can effectively reduce friction and heat in bearings by forming a lubricating film. The lubricating film can reduce friction and prevent direct contact between metal parts, thereby extending bearing life. At the same time, the lubricating film can also absorb and disperse the heat generated during friction to prevent the bearing from overheating.

However, the sealing of the lubricant directly affects the lubrication effect and leakage of the bearing. During bearing operation, the lubricant is prone to leakage due to its special lubricating properties. Therefore, measures must be taken to maintain the sealing of the lubricant to prevent leakage and contamination.

A common measure is to use a seal. A seal is a sealing device installed on the bearing and bearing housing, which can effectively prevent lubricant leakage and contamination. Seals are usually made of rubber or metal and are installed on the shaft where the bearing rotates. When the shaft rotates, the seal makes close contact with the shaft, forming a sealed space to prevent lubricant from leaking into the external environment.

In addition to seals, there are other sealing devices available, such as gaskets and sealing strips. These sealing devices are simple in structure and easy to install, and can effectively maintain the sealing of the lubricant and prevent bearing leakage and contamination.

To ensure the normal operation of compressor bearings, reduce friction and heat, and improve operating efficiency, the sealing of the lubricant is crucial. Seals and other sealing devices can effectively maintain the sealing of the lubricant, prevent leakage and contamination, and improve the lubrication effect of the bearing, prolonging its service life. Therefore, in compressor maintenance, it is important to select the appropriate lubricant and sealing device to maintain good lubrication of the bearing.
