Impellers feature complex structures with narrow blade gaps and winding internal flow passages. Traditional manual scrubbing and high-pressure spraying struggle to reach inner cavities. Cutting fluid, iron filings and adhered oil stains trapped in blind spots are difficult to remove, which may adversely affect dynamic balance, assembly accuracy and service life of finished products. Tailored for mass cleaning of turbine impellers, compressor impellers and precision pump impellers, the Buck automatic ultrasonic cleaning machine for impellers adopts proven ultrasonic cavitation cleaning technology and integrates multi-process automation workflows, delivering a stable and standardized cleaning solution for precision impeller manufacturing.

Equipped with a PLC and touch screen intelligent control system, the machine uses servo manipulators for automatic loading and unloading. It runs through a complete sequence of main ultrasonic cleaning, multi-stage rinsing, air cutting dewatering and hot air drying without manual operation. Operators only need to set parameters such as cleaning duration, ultrasonic power, liquid temperature and rinsing cycles on the touch panel before starting batch operation with one click. Process parameters can be saved in groups to accommodate impellers of different materials and sizes. It ensures consistent cleanliness across batches and eliminates instability caused by manual work.

The core cleaning unit is fitted with high-performance ultrasonic transducer systems. Through ultrasonic cavitation, countless tiny bubbles form in the cleaning solution. When these bubbles collapse inside blade gaps and intricate flow channels, they generate micro-jets that penetrate hard-to-reach areas including flow passages, blade roots and micro clearances to gently strip oil stains, cutting residues and fine metal chips. Unlike abrasive brushing or polishing, ultrasonic cleaning is a controllable physical process. Under normal operating conditions, it will not scratch blade surfaces or damage the machined profile of impellers. It realizes non-destructive cleaning and guarantees the dynamic balance performance of impellers.

The tank and all wetted parts of the machine are made of high-quality stainless steel for corrosion resistance and long service life. A built-in circulation filtration system continuously separates iron filings and impurities from the cleaning liquid, extending the service cycle of the detergent and cutting consumable costs. Combined air cutting and hot air drying is adopted: strong airflow first blows away most free water on the workpiece surface, followed by uniform hot-air drying. This prevents water stains and marks, reducing the risk of oxidation and rust after cleaning. Cleaned impellers can be directly transferred to subsequent inspection and assembly processes.

The machine is designed with reliability and safety in mind, featuring liquid level protection, temperature control protection, overload alarm and fault indication. Its enclosed structure reduces mist leakage and improves the working environment. Flexible customization is available according to customers’ impeller dimensions and production capacity, including adjustment of station quantity, cavity size and conveying rhythm. It is widely used for turbocharger impellers, new energy fluid impellers, pump impellers and other components in mass production lines for automotive, fluid machinery and precision machining industries.

Against the backdrop of quality improvement and cost reduction in precision manufacturing, the Buck automatic ultrasonic cleaning machine for impellers addresses major pain points such as difficult cleaning of deep flow channels, high labor cost and unstable cleanliness. It standardizes and automates the impeller cleaning process, steadily meeting mass-production cleanliness specifications, helping manufacturers raise yield rates and shorten production cycles. It is the preferred cleaning equipment matched with precision impeller processing lines.
