Description

TECHNICAL FIELD

[0001] The utility model relates to air compressor technology field, concretely relates to an air compressor oil mist eliminator oil collecting system. BACKGROUND

[0002] The air compressor plays a pivotal role in the aluminum industry, and its operating condition directly affects the smoothness of the entire production process. During the operation of the air compressor, the oil mist separator plays a key role, as it can effectively separate the oil mist in the compressed air from the air to ensure the purity of the compressed air and thus ensure the normal operation of the subsequent equipment. The separated oil is returned to the oil tank through the oil return pipe, and this process poses a risk of damage to the machine due to impurities in the returned oil.

[0003] Specifically, dust, particulate matter, and other impurities in the air inevitably mix into the returned oil. Over time, these impurities accumulate and gradually contaminate the lubricating oil in the oil tank. The originally pure lubricating oil is eroded by impurities, greatly reducing its performance and forcing the use cycle to be shortened. When the lubricating oil fails to achieve the desired lubricating effect, the components of the air compressor will be worn out during high-speed operation, which may lead to reduced equipment efficiency, equipment failure, or even damage to critical components, causing the air compressor to malfunction and seriously affecting the production progress of the aluminum industry, resulting in significant economic losses for the enterprise.
