二、规格及技术参数Specifications and Technical Parameters

三、结 构Structure

     T35系列轴流通风机由机壳、叶轮、集风器，电机与支架组等部分组成。

1)   机壳：由圆形风筒及支架组成，采用钢板焊接，安装方便。

2)   叶轮：由4片扭曲型叶片及轮毂组成。采用Q235钢板制成，叶片按照客户选用安装角度焊接于轮毂上。

3)   集风器：由集风器法兰、集风器组成。集风器为圆弧流线形，可减少气流入口损失。

T35 series axial fan is composed of a casing, an impeller, the wind collecting device, motor and support groups and other components.

1): composed of a circular cylinder shell and a support bracket, with steel plate welding, convenient installation.

2): by 4 twisted impeller blades and a wheel hub.Using Q235 steel, blade installation angle according to the customers choice of welding on hub.

3) the wind collector: by the wind collector flange, the wind collector.The wind collecting device for circular arc streamline, can reduce the air entrance loss.

四、安装、使用与维护Installation, Use & Maintenance

(1)安装前Before installation

应对风机各部件进行全面检查，机件是否完整、叶轮与标示的旋转方向是否一致，各部件联结是否紧密；主要机件有无损伤、传动部分是否灵活等等。

With the wind turbine components to conduct a comprehensive inspection, work is complete, the direction of rotation of the impeller and the label is consistent, each component connection close together; the main parts have no injury, transmission part is flexible and so on.

(2)安装时Installation

注意检查机壳内不应有掉入、遗留的杂物及工具。在一些结合面上为了防止生锈，减小拆卸困难，应涂一些润滑脂或机油。风机与基础结合面、进出风管的连接处应调整使其自然吻合，不得强行联结。更不许将管道重量加在风机各部件上，并注意保证风机的水平位置。

Pay attention to check the cabinet should not fall, remaining debris and tools.In some combination surface in order to prevent rust, reducing the disassembly difficulty, should put some grease or oil.Fan and the foundation with surface, out of the air duct connection should be adjusted so that its natural anastomosis, can not be forcibly coupling.More will be allowed to pipeline weight is put on the wind turbine components, and ensure the fan in the horizontal position.

(3)风机的操作Fan operation

风机全部安装完毕，在总检合格后，才能进行试运转。试车时人数不少于两人，一人控制电源，一人观察风机运转情况，发现异常现象立即停机检查；首先检查旋转方向是否正确；风机开始运转后，应立即检查运转电流是否平稳、电流是否超过额定电流；若有不正常现象，应立即停机检查。检查风机各部分的间隙尺寸，转动部分与固定部分有无碰撞及磨擦。确定无异常现象后才能再次开机运转。

Fan installed all qualified, in general, to make a test run.The test of more than two people, a control power supply, a human observer fan operation, abnormal phenomena immediately stop check; first checks the rotation direction is correct; fan started running, should immediately check the operating current is stable, current is over the rated current; if there is not a normal phenomenon, should stop immediately. Check.Check the fan part of the gap size, rotating part and a stationary part has no collision and friction.Determination of no abnormal phenomenon when another operation boot.

 (4)风机的维护Fan maintaining

为了避免由于维护不当而引起人为故障及自然事故的发生，充分发挥设备的效能，延长设备的使用寿命，必须加强风机的维护。

1）只有在风机设备完全正常的情况下方可运转，定期清除风机内部的积灰、污垢等杂质，并防止生锈，为确保安全，风机的维护必须在停车时进行。

2）在风机开车、停车或运转过程中，如发现不正常现象应立即进行检查。

In order to avoid human error caused by improper maintenance and natural occurrence , give full play to the performance of equipment ,Extend the useful life of equipment , maintenance of the fan must be strengthened .

1)        Only the fan device is fully operational only under normal conditions , periodically clear the fan inside the fouling , dirt and other impurities , and to prevent rust , to ensure the safety , maintenance must stop the fan when .

2)        In the fan driving , parking or operation of the process , found irregularities should be immediately checked.

五、常见故障分析Common problems Analysis

（1）  风机产生振动的原因很多，可从下述几个方面检查：

1）叶轮旋转时碰撞机壳，此时会发出异常声音，原因可能是机壳或叶轮变形。

2）叶轮动平衡被破坏，原因可能是叶轮变形、叶片积灰、叶轮与主轴的联结松动、轴承箱螺栓松动及轴承损坏。

3）风机基础刚度不够。

4）风机进出口安装不良。

（1）    Fan vibration for many reasons , can be checked from the following aspects :

1）Impeller rotation collision case , abnormal sound will be issued at this time may be due to deformation of casing or impeller .

2）Balancing the impeller is damaged , probably due to deformation of the impeller , blade fouling , loose coupling impeller and spindle , bearings and bearing box bolt loose damage .

3）Not enough fan base stiffness.

4）Import and export of poorly installed fan .

（2）  电机电流过大或温度升高，原因可能有以下几点：

1）电机轴承损坏。

2）电压低或电源单相断电。

3）系统阻力过大。

4）输送气体密度过大。

5）输送气体温度过高。

(2) the motor current is too large or the temperature is increased, the reason may have the following several points:

1) motor bearing damage.

2) low voltage or power single-phase power.

3) system to high resistance.

4) conveying gas density is too large.

5) conveying gas temperature too high.
