SHAFT SEAL FOR AN OPEN-DRIVE COMPRESSOR |
摘要 |
Devices and methods for maintaining lubrication of a shaft seal of an open-drive compressor that is operating in a vacuum condition. The external side of the shaft seal allows retention of a volume of lubricant for extending the lifespan of the shaft seal for the open-drive compressor. The devices can also reduce and/or prevent deterioration of the shaft seal regardless of the operation condition of the open-drive compressor. The devices can further reduce and/or prevent leakage of a lubricant and/or refrigerant that can cause deterioration of components within a transport refrigeration unit (TRU). |
