Korkeapaineinen hienosumuinen vesisumun sammutusjärjestelmä

1. Appearance Quality Inspection: All pump components are manufactured using high-pressure die-casting. The outer surfaces must be smooth and flat, free from defects such as pitting, scabs, bubbles, or sand holes. No materials prone to corrosion or peeling, such as spray paint or plastic coating, shall be incorporated. ▲2. Start-up Time: ≤3.00s 3. Continuous Operation Performance: With sufficient oil and water supply, the fine water mist system operates continuously for 15 minutes without abnormalities. 4. Single-Bag Operation Performance: With sufficient oil supply, the single-bag system operates continuously for 5 minutes without abnormalities. ▲5. Noise Level: Ear-level noise: ≤95dB (A) 6. Structural Inspection: ▲6.1 Frame and Back Support: Utilizes a closed-type, high-strength 304 stainless steel protective frame with anti-corrosion treatment. Water bag mounting points include reinforcement supports. 6.2 Backpack Assembly: Consists of a main compartment, carrying system, two fixed auxiliary pouches, and a removable auxiliary pouch. The carrying system includes a back frame, dual shoulder straps rated for 50kg load, ergonomically designed straps with quick-release buckles, back padding, and a waist belt. The main backpack features a soft top handle for easy transport; a prominent central area on the top is available for custom printing. Four reflective markers are positioned on prominent areas of the main backpack and auxiliary pouches. ▲6.3 The accompanying engine is a single-cylinder, four-stroke, air-cooled gasoline engine. The engine nameplate indicates a power rating of 1.8HP/7000rpm. 6.4 The grease-free piston-type, horizontal-shaft, dual-outlet high-pressure water pump features a copper pump head. Each high-pressure connection uses a copper quick-connect fitting. The pump body is made of nylon-glass fiber composite material, while the piston is made of fluorine rubber, offering wear resistance and durability. 6.5 The water gun connects to the main unit via a quick-connect interface. The inlet and outlet connections use quick-plug connections with 3/8" interfaces and feature self-priming dual-hole conversion for water intake. ▲6.6 Main unit comprises gasoline engine, liquid pump, hose connectors, pressure regulator, spray assembly, suction assembly, nozzle, water tank (water bladder), backpack, etc. Spray gun assembly allows interchangeability between foam gun and water gun, enabling dual functions of foam spraying and high-pressure fine water mist. Foam gun is modular with stainless steel body and anodized aluminum alloy nozzle. Features an independent foam liquid bottle, foam formation chamber, conical spray channel, and air mixing orifice: Rated flow rate: 18 L/min Maximum range: (Foam) 7m, (Water) 8m Operating pressure: 5 MPa Rated flow rate (Water): 5 L/min Foam expansion ratio: 4:1 Foam solution mixing ratio: 1% Minimum continuous operation time: 4 min ▲6.7 Spray Nozzle Users may optionally equip a rotating hexagonal multi-angle nozzle with marked spray angles of 0°, 15°, 25°, 40°, 50°, and 65° to achieve six distinct spray patterns: mist, scatter, direct jet, and fan spray. The spray pattern can be switched between full-body water jet, mist spray, and fan-shaped water mist by rotating the gun body. ▲6.8 The spray gun body features a handle-type switch grip, supporting a two-stage extendable spray gun with a telescopic spray rod. The retracted length is 0.6m, fitted with a stainless steel hose. The gun rod is available in stainless steel or copper material, featuring a three-section telescopic rod with a maximum length of 1.5m. ▲6.9 The water bag backpack is constructed from military-green high-strength waterproof fabric. The water bag itself is made of heat-bonded PVC material, offering impact resistance and abrasion durability. The outlet connection exhibits no leakage. Water bag capacity exceeds 22L. The number of water bags can be customized as needed. Water bag dimensions: 380mm x 300mm x 190mm. Features a dual-shoulder carrying system. The water inlet uses a threaded cap for durability and leak prevention. The outlet employs a stainless steel quick-connect fitting with excellent sealing performance. 6.10 The engine starts via a pull cord. A one-button electric start can be added as an optional feature. 6.11 Fine mist system incorporates an automatic pressure regulator. When the pump operates at high speed, closing the spray gun automatically resets system pressure to zero. Upon reopening the spray gun, pressure instantly returns to normal. ▲6.12 Net weight: ≤8.5kg ▲6.13 Total equipment weight: ≤35.00kg ▲6.14 Fuel tank capacity: ≥0.75L ▲6.15 Water Bag Capacity: ≥22L ▲6.16 Water Bag Replacement Time: ≤5.00s ▲6.17 Equipment Dimensions: 420mm x 300mm x 170mm ▲7.
