Marine Explosion-Proof Fans With Water Driven
1. Fan General
CSZ, CSL water-driven explosion-proof axial fan with water driven have anti-high hazard classification, sound anti-wooble, anti-vibration and anti-impact performance. The fan of single stage, low weight, small size, simplicity of operation and it was in a post- stability / normally only one operator of required. Driven directly by fire protection water, this ventilator depends on no other power. With sealed bearings, it gives good service at temperatures. Blast safety of this type is also called a water turbine (or water turbine impeller motor) to overheat with water.
2. Structure
CSZ series ventilator fan is composed of water turbine, frame, casing, rotor and impeller. The water turbine is precisely cast of anti-corrosion copper alloy, the casing is soldered of austenitic stainless steel. The impeller is made of high strength aluminum alloy with the whole structure of no-spark design. The angle for air are 18° for air supply and 22° for air return. A kind of nozzle for discharge in a possible direction.

3. Fan applicable conditions
For places where there are explosive grade IIB and IIC and group from T4 to T6, the air temperature is from -25°C~+55°C; relative humidity of the air: ≤ 95%; cyclical ventilation: 22~9 (24~26) etc.; air pressure: ±10Kpa; saturated air humidity: 100%; vibration: 10mm; shock: existence.
