Hydraulic valve blocks, piston pump housings, motor housings, oil manifolds, hydraulic fittings, precision valve spools, and die-cast hydraulic housings for construction machinery. The equipment removes cutting oil, aluminum & iron chips, abrasive dust and sludge contaminants trapped in deep holes, blind holes and intersecting oil galleries. It delivers cleanliness conforming to strict industry standards of NAS8–NAS9, effectively preventing valve spool sticking and system abrasion failures.
Conducted in a fully sealed vacuum environment, the process combines high-frequency ultrasonic waves with 360° high-pressure spraying to thoroughly eliminate residues inside blind holes and slender damping holes. It integrates cleaning, rinsing and vacuum drying in one cycle, leaving parts free of water stains and oxidation rust. The solvent distillation recovery rate reaches ≥98%, delivering energy and environmental conservation while supporting seamless integration into automated mass production lines.
Programmable multi-angle high-pressure water jets target and remove flanging burrs at oil hole openings as well as aluminum debris inside internal galleries. Managed by intelligent PLC programming, all cleaning parameters can be saved and recalled to guarantee consistent cleanliness across every batch of parts. This solution is optimized for large hydraulic housings of construction machinery.
Adopting multi-stage ultrasonic cleaning, turbulent flow rinsing and hot air vacuum drying with eco-friendly water-based detergents, this economical option is designed for degreasing and chip removal of standard machined hydraulic components with lower upfront equipment investment.
Deep, Dead-Angle-Free CleaningCombined vacuum, ultrasonic and high-pressure spray composite processes solve the challenge of removing contaminants lodged in deep holes and intersecting galleries of hydraulic components.
Controllable & Standardized CleanlinessParticulate pollutants are controlled at the micron level, meeting assembly specifications of foreign hydraulic manufacturers including Eaton and Komatsu. Our equipment supports domestic substitution of imported cleaning machines under the Bakrclean system.
Fully Automatic Intelligent OperationThe whole machine is intelligently controlled by PLC. Robotic loading and unloading can be equipped to achieve seamless connection with customers’ automated production lines.
Safe & Eco-Friendly OperationFully sealed vacuum working environment with explosion-proof design for hydrocarbon solvents, minimal waste liquid discharge, fully aligning with green factory standards.
