I. Compatible Workpieces (Full Coverage of Hydraulic Industry Components)

Hydraulic valve manifolds, hydraulic valve bodies, servo valves, hydraulic motors, piston pump housings, cylinder parts, hydraulic circuit integrated blocks, hydraulic fittings, hydraulic spools, valve plates, and precision hydraulic castings for construction machinery.

Core Pain Points

These parts feature intersecting bores, deep blind holes, tiny oil galleries, and micron-level fitting clearances. Residues including aluminum/iron chips, cutting fluids, and die-casting release agents readily accumulate inside. Contaminants often lead to spool seizure and abrasive failure of hydraulic systems.

II. Scenario-Based Equipment Selection Solutions (Customized to Production Capacity & Cleanliness Requirements)

Solution 1: High-Volume Mass Production · Ultra-High Cleanliness

(For new energy, construction machinery, aerospace hydraulic components; Cleanliness Class NAS6 ~ NAS3)

Equipment: Fully Automatic 4/5-Tank Vacuum Hydrocarbon Cleaning Machine

Standard 5-Tank Process Flow

Vacuum Rough Washing → Degassed Ultrasonic Precision Washing under Vacuum → Multi-Stage Vapor Rinsing → Independent Solvent Distillation & Regeneration Tank → Low-Temperature Vacuum Drying

Core Advantages

1. Five fully isolated process stations eliminate secondary cross-contamination from light and heavy contaminants.

2. Dedicated distillation tank enables 24-hour continuous solvent regeneration with a recovery rate of ≥98%.

3. Vacuum negative pressure penetrates narrow deep blind holes of 2–3 mm, completely stripping micron-scale metal swarf trapped at hole bottoms.

4. Fully enclosed explosion-proof design with low VOC emissions; delivers watermark-free, oxidation-free surfaces, consistently complying with ISO18413, VDA19 and NAS1638 cleanliness standards.

Applicable Workpieces

Mass-produced high-end valve manifolds, servo valves and precision piston pump assemblies.
