"B"： ex-proof
"Z"： axial fan
"30~180"： impeller diameter
Components
Fan is mainly composed of casing, impeller, vane supporting feet and marine motor.
Function
It can be used to transport Group B T1～T4, Group C T1～T5 flammable, explosive gas in ships, vessels and platforms.
Advantages
Fan has the features of low noise, large air volume, big pressure head, high efficiency. It has good corrosion resistance, shock resistance, the running is stable and safe, reversible operation can be selected according to users’ requirements.
Fan can be made into various types for users to select: Ⅰtype（deck type）、II type（air duct type）、III type（separate cabins type）、IV type（olive type）、V type（upper outlet type）。
基本参数：
● air flow：500～180000m3/h
● total pressure：100～1050Pa
● power：0.55kW~90kW
● Power supply: standard configuration AC 3PH 380V/50Hz，AC 3PH 440V/60Hz，if need can choose：AC 3PH 415V/50Hz，AC 3PH 460V/60Hz，AC 3PH 480V/60Hz，AC 3PH 690V/60Hz.
● Casing: structure is barrel type; in casing, the impeller rotating parts set spark-proof copper ring, act as ex-proof function. The casing main function is to gather gas and guide gas, improve fan efficiency; support motor and protect impeller.
● Impeller: structure is wing type blade; material is ZL104 cast aluminum alloy, it has passed strict dynamic balance correction, over-speed test.
● Vane supporting feet: the function is to connect motor and barrel, at the same time, it adopts twisted blade type guide vane structure, the function of guide vane is to gather the gas from impeller, and convert part of the kinetic energy into pressure energy.
● Marine ex-proof motor: It has good anti-moisture, anti-mould and anti-salt mist, stable operation, and low noise. The structure is hermetic three phase AC cage type rotor asynchronous motor. It can prevent dust, scrap iron or other sundries from entering into motor and satisfy hostile environment on the sea. Working principle: Alternating electric field generates alternating magnetic field through coil, the change of magnetic flow generates magnetic field force in rotor winding, and drive rotor rotation, convert electric energy into mechanical energy. Motor ex-proof performance satisfies GB3836.1-2010《Explosive environment, part 1: general requirements for equipment》, GB3836.1-2010 《explosive environment part 2: the flame-proof casing" d "protection equipment》. Space heater can be added according to requirements.
● Marine ex-proof motor can choose Dezhou HL, Jiangsu Dazhong, Yuandong and other domestic brands, also can choose ABB, Siemens and other foreign brand.
应用场合：
It can be used to transport Group B T1～T4, Group C T1～T5 flammable, explosive gas in ships, vessels and platforms.
