High Pressure Water Cannon Nozzle Seat Precision CNC Machining
The high-pressure water cannon nozzle seat is a core executive component of special robots' firefighting systems. It works by gathering pressure energy of high-pressure water through precision internal flow channel design and converting it into kinetic energy to form high-speed jets for firefighting or cleaning operations. This product uses high-strength aluminum alloy and stainless steel materials, formed through five-axis CNC precision machining to ensure internal flow channel geometric accuracy and surface smoothness, significantly improving jet density and range. Designed specifically for explosion-proof, rescue, aerospace and other special robots, it can operate stably in extreme environments such as flammable, explosive, toxic, and oxygen-deficient conditions.
Features
- Precision flow channel design: Adopts conical with cylindrical outlet section nozzle structure, reducing turbulence and cavitation, improving flow coefficient and jet density
- High-strength materials: Main body uses aviation-grade aluminum alloy (compliant with GB/T9438) and stainless steel components, seals comply with HB5584 standard, bearing nominal pressure up to 1.2MPa
- Multi-function adaptation: Supports both columnar jet (range 35-45 meters) and mist jet (coverage width over 10 meters) modes, with 360° horizontal rotation and 195° vertical adjustment
- Smart integration: Can integrate sensors and intelligent control units for remote control and automatic mode switching, suitable for unmanned operations
- Extreme environment adaptability: Through special surface treatment and material selection, corrosion-resistant, high-temperature resistant, suitable for various extreme environments including firefighting, explosion-proof, rescue and aerospace
