[0002] Multi-pipeline lubricating oil sediment refers to the sediment produced by the lubricating oil used in the multi-pipeline system after long-term operation. These sediments are usually deposited due to chemical changes of impurities or additives in the oil under high temperature or pressure conditions. They may cause pipeline blockage, equipment failure or reduced lubrication effect. Regular cleaning and maintenance are essential to prevent the accumulation of multi-pipeline lubricating oil sediment. The multi-pipeline lubricating oil sediment filter is a pipeline structure used to filter sediment;

[0003] Most of the existing multi-pipeline lubricating oil sediment filtering devices use a simple filter screen structure installed in the pipeline, but the filter screen structure is located inside the pipeline, and its installation and disassembly process is cumbersome, resulting in long equipment downtime, reducing equipment production efficiency, and making it difficult to meet actual usage needs. Utility Model Content
