Optimized Internal Structure Enables Yida Pumps to Handle Gas-liquid Mixed Media in Aeration and Chemical Oxidation Wastewater Treatment Systems Globally

Advanced oxidation wastewater treatment processes, aeration stirring circulation systems and ozone disinfection water supply systems all have gas components mixed in the liquid phase. When ordinary pumps transport such media, the gas accumulated inside the pump cavity will form an air plug, blocking the normal flow of liquid, resulting in flow drop, pressure fluctuation and even complete flow interruption. Long-term gas accumulation will also cause the bearing assembly to lose liquid lubrication and produce dry grinding damage, accelerating pump failure.

Yida adds an independent micro exhaust channel at the top of the pump cavity, so that the gas entering the pump body can be automatically discharged along the exhaust channel during operation, avoiding the formation of air plug accumulation inside the pump cavity. The bearing assembly adopts a self-lubricating structural design that can maintain short-term operation under insufficient liquid lubrication conditions, and will not suffer instant ablation damage when a small amount of gas passes through. The impeller structure is adjusted to improve the stirring and mixing capacity for gas-liquid two-phase media, maintaining stable output flow under a certain gas content ratio.

Gas-liquid adaptive pumps are widely used in ozone oxidation wastewater treatment, Fenton oxidation reaction systems, aeration circulation of electroplating liquid medicine and other process links containing gas-liquid mixed media. Compared with positive displacement pumps specially used for gas-liquid mixing, the optimized centrifugal anti-corrosion pump has obvious cost advantages and is more suitable for large-flow circulation scenarios with low gas content ratio.

This performance optimization expands the application range of Yida's anti-corrosion pumps in the field of wastewater advanced treatment, matches the technological upgrading trend of global industrial wastewater treatment towards high-standard discharge, and provides cost-effective fluid delivery solutions for more new wastewater treatment processes.
