AI Technical Summary
Existing lubricating oil storage tanks generate sludge during long-term use, resulting in space occupation and a decline in lubricating oil quality. Traditional filters require frequent disassembly and rinsing, which affects the production process.
The pulse backwash self-cleaning structure adopts a conical filter cover and an external filter. Lubricating oil is drawn by a centrifugal pump and pulsedly sprayed onto the conical filter cover by a spray head. Sludge and impurities are transferred to the external filter. Cleaning is performed after a short shutdown, reducing the impact on production.
It enables the effective removal of sludge from the conical filter cover without affecting production, reducing downtime and workload for cleaning personnel, and improving lubricant quality and production efficiency.
