一、概述 

CQ系列船用离心通风机（以下简称通风机）可输送空气，含有盐雾的海洋空气和含有油雾等腐蚀性空气，通风机适用于船舶上各种舱室的通风换气、锅炉通风，也可适用于其他适当的场合。

通风机是按照国标GB/T11865《船用离心通风机》和现行的《钢质海船建造规范》设计制造的。

二、特点

    尺寸小、重量轻、低噪声、防腐性好、气密性好、启动力矩小、抗摇摆、振动和冲击性强。

 三、结构形式 

    通风机为卧式，电动机直联式结构，亦可制成立式结构。 

    叶轮由铝合金材料铆接制成，并经静、动平衡校正。

    机壳、进风口等采用普通钢质材料焊接而成，并制成气密式结构。

    通风机可制成顺时针旋转（右转）或逆时针旋转（左转）。
    逆转（左转）一从电动机端正视，叶轮按逆时针方向旋转，以“L”表示。

    顺转（右转）一从电动机端正视，叶轮按顺时针方向旋转，以“R”表示。   

1.General

CQ series marine centrifugal fans (simply the fans) are capable of blowing air, such as ocean air containing salt vapor and corrosive air containing oil vapor and a small quantity of acid steam which generated by the natural evaporation of the batteries. So it can be widely used for ventilation of various cabin rooms and the boiler, they are also applicable in other places that suit.

The ventilator is designed and manufactured according to the standard of GB11865 《Marine Centrifugal Fan》and 《The manufacture Rules of Sea-going Steel Ships》which approved by the Register of the People's Republic of China.

2.Characteristics

Small in size and light in weight . Low noise and low vibration .

Good anti-corrosiveness. Good air tightness

Small starting torque. Strongly performance of resisting vacillation, vibration and shocking

3.Structure type

The ventilator is designed and manufactured into a horizontal structure type, also can be a vertical one. The vane wheel is rivet directly on the motor shaft extension. The vane wheel, being riveting structure is made of aluminum alloy and carefully balanced in static and dynamic ways.

Both the machine casing and the entrance are made of welded common steel.

  The ventilator can be made for Contra rotate (turn left) or Clockwise rotation (turn right):

  Contra rotate (turn left) - viewed from the motor indicated as “L”.

  Clockwise rotation (turn right) -viewed from the motor side, the vane wheel rotates clockwise and indicated as “R”.
