Title:
COMPRESSOR SYSTEM AND OPERATION METHOD FOR COMPRESSOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/046122
Kind Code:
A1
Abstract:
A compressor system and an operation method for a compressor system. The compressor system comprises a first compressor (10), a second compressor (20) and an oil balance pipe (50), wherein the first compressor (10) and the second compressor (20) are arranged in parallel; an oil tank of the first compressor (10) is in communication with an oil tank of the second compressor (20) by means of the oil balance pipe (50); the first compressor (10) is provided with a monitoring apparatus (17) for monitoring lubricating oil in the oil tank of the first compressor (10); the second compressor (20) has a protection apparatus (25) for shutting down the second compressor (20) when the operation of the second compressor (20) is abnormal; and the monitoring apparatus (17) is connected to the protection apparatus (25), such that the protection apparatus (25) can shut down the second compressor (20) in response to a signal indicating that a monitoring value of the lubricating oil exceeds a predetermined range. The compressor system realizes the balance of lubricating oil by using a protection apparatus (25) of a second compressor (20), without the need to use an additional or dedicated control apparatus, thereby simplifying the structure and operation of the compressor system, and reducing the cost of the compressor system.
