Recently, the high-power (3500KW) full-rotation rudder propeller device developed and produced by Wuhan Ship Machinery passed the acceptance test of experts from Harbin Engineering University, CCS Wuhan Branch, China Oilfield Service Division and 702. The research and development of the high-power full-rotation rudder propeller device is the third of the national high-tech ship scientific research project "Development of Dynamic Positioning System". It is the most important propeller in the dynamic positioning thruster system. The full-rotation rudder propeller device can be in the 360Â° range. The thrust is generated in any direction inside and can be widely applied to various ships and platforms. At present, the high-power full-rotation rudder propeller device is basically monopolized by famous foreign manufacturers such as Sweden Rolls-Royce, Holland WÃ¤rtsilÃ¤, Germany SCHOTTEL, and Japan Kawasaki Heavy Industries.
The successful development of the project and the acceptance of the project broke the monopoly of foreign companies, filled the gap in the manufacture of domestically-adjusted high-power full-rotation rudder propellers, solved the domestic manufacturing and assembly problems of the device, and found a solution for adapting to special ship applications. An optimized solution.
Uv laser marking machine beam quality, focusing spot is very small, can achieve hyperfine marking. Most materials can absorb ultraviolet laser, so their application range is wider. Uv laser is a cold light source, laser marking or laser cutting when the thermal impact zone is very small, will not produce thermal effect, laser 20,000 hours free of maintenance, no consumables, low cost, energy saving. Label environmental protection, in line with ROHS standards.
The reaction mechanism of ultraviolet laser marking machine is achieved by photochemical ablation, that is, breaking the bonds between atoms or molecules with laser energy, making them gasify and evaporate into small molecules. Focusing spot is very small, and the processing heat affected area is very small, so it can be ultra-fine marking, special material marking, is the preferred product for customers with higher requirements on the marking effect.
Uv laser marking machine is widely used in consumer electronics, mobile phone parts, LCD screen engraving qr code and trademark, ceramics, sapphire chip, FPC flexible circuit board micro hole drilling, cutting, biomedical glass marking, capacitive touch screen ITO etching. "Metallic or nonmetallic surface markings."
