AI Technical Summary
In existing built-in oil-gas separators, some of the oil-gas mixture flows out with the oil outlet during the oil-gas separation process, resulting in insufficient separation. Furthermore, the oil droplets that collide and drip cannot quickly gather together, causing accumulation and affecting the separation effect.
An integrated oil-gas separator was designed, comprising an oil-gas separation chamber, an oil baffle block, a return oil baffle plate, a valve assembly, and an automatic switching assembly. Through multiple collisions and the cooperation of the return oil baffle plate, oil-gas separation is achieved. The oil guide plate quickly collects oil droplets, and the valve assembly prevents the oil-gas mixture from flowing out with the oil outlet.
It improves the efficiency of oil-gas separation, ensures better oil-gas separation effect, prevents oil droplet accumulation, and enhances the working efficiency of the separator.
