Against the backdrop of industrial upgrading in precision manufacturing and tightening environmental policies, traditional water-based cleaning and halogenated solvent cleaning solutions struggle to balance cleanliness, safety and green production requirements. As a representative of domestic precision cleaning equipment, Sinobakr hydrocarbon cleaning machine relies on core technologies including vacuum sealing, composite ultrasonic cleaning and solvent distillation regeneration. It is widely used in automotive parts, hydraulic valves, aerospace components, bearings and precision hardware processing sectors, providing mature and reliable integrated solutions for industrial precision degreasing.

The Sinobakr hydrocarbon cleaning machine adopts high-purity hydrocarbon solvent as the cleaning medium and combines vacuum negative pressure, high-frequency ultrasound, vapor bath cleaning and vacuum drying processes. During operation, a vacuum environment is formed inside the cleaning chamber to extract air from blind holes and cross oil passages of workpieces and eliminate air blockage, so that hydrocarbon solvent can fully penetrate tiny gaps. With the cavitation effect of ultrasonic waves, microbubbles generated by the solvent burst continuously to strip cutting oil, rust-preventive oil, metal debris and carbon deposits attached to workpiece surfaces and deep holes. Based on the principle of like dissolves like, hydrocarbon solvents dissolve oil stains. They are compatible with various base materials such as aluminum alloy, cast iron, stainless steel and powder metallurgy, without corroding workpieces or causing oxidation whitening on aluminum parts. Cleaned workpieces gain short-term rust resistance without additional anti-rust procedures. Vapor bath cleaning further removes trace surface residues, followed by vacuum low-temperature flash drying. Workpieces are thoroughly dried both inside and out with no water marks or solvent residues, achieving cleanliness up to NAS 7–8 grade and meeting the micron-level particle control standards of main engine manufacturers.

Safety design is a prominent advantage of Sinobakr equipment. The whole machine is equipped with full explosion-proof configuration of Ex IIB T4, including explosion-proof motors and explosion-proof electric control systems with indirect heating by heat-conducting oil. The chamber adopts solvent-resistant fluororubber seals to prevent solvent leakage. A real-time combustible gas monitoring module is built into the device. It will automatically alarm and shut down when solvent concentration exceeds the limit. The whole process operates in a closed environment with almost no pungent odor in the workshop, complying with factory fire protection and safety production inspections.

Built-in vacuum distillation and regeneration system is the key to energy conservation and environmental protection. Contaminated hydrocarbon solvent flows into the distillation unit, where oil dirt and metal residues are separated under low-temperature vacuum. Purified solvent is condensed and recycled for repeated cleaning, achieving a solvent recovery rate of over 95%. The amount of hazardous waste generated is extremely low, realizing waste liquid reduction. Compared with open cleaning equipment, the consumable cost is greatly reduced. No wastewater treatment facilities are required, making it easier to pass environmental assessment and fitting the low-carbon production trend of manufacturing industry. The whole system is fully automatically controlled by PLC and touch screen. Workpiece cleaning, rinsing, distillation and drying run automatically. It can work as a standalone unit or connect to automatic production lines, supporting multiple cleaning actions such as workpiece swinging and rotation to adapt to parts with different structures.

Sinobakr breaks the monopoly of imported precision cleaning equipment. As a self-developed brand with years of experience in the domestic cleaning industry, it holds ISO9001, CE explosion-proof, UL and other certifications. It satisfies three core demands: cleaning precision, production safety and operating cost. As the precision machining industry keeps raising cleanliness requirements for components, Sinobakr vacuum hydrocarbon cleaning machine stands out for its comprehensive strengths of closed explosion-proof design, solvent recycling and precise deep cleaning. It has become a preferred alternative to traditional cleaning processes in precision manufacturing, helping the industrial manufacturing sector advance toward high precision and green development.
