工业风机和鼓风机介绍(中英文)
概述:
OVERVIEW:
许多风机和鼓风机属于工业风机、工业鼓风机、工业排气机、排气鼓风机、工业冷却风机、工业排风机、工业通风风机、工业离心风机和叶轮风机的分类。它们都属于工业风机的两种基本类型之一: 离心式或轴流式。
Many fans and blowers fall under the classifications of Industrial Fans, Industrial Blowers, Industrial Exhausters, Exhaust Blowers, Industrial Cooling Fans, Industrial Exhaust Fans, Industrial Ventilation Fans, Industrial Centrifugal Fans, and Impeller Fans. They are all one of two basic types of industrial fans: Centrifugal or Axial.
“工业”风机一词没有明确的定义,但该术语旨在表示满足工业操作需求的较重结构的风机。与商用或暖通空调风机相比,这可能包括使用更厚的材料规格、更大的轴、延长轴承寿命的轴承、高温特性、耐腐蚀材料等。
The term "industrial" fan does not have a clear definition, but the term is intended to mean a fan of heavier construction to meet the demands of industrial operations. This may include the use of thicker material gauges, larger shafts, bearings with increased bearing life, high temperature features, corrosion resistant materials, etc. compared to commercial or HVAC fans.
离心式风机或鼓风机使用封装在涡形外壳中的七种类型的轮子之一。空气通过壳体入口进入风机叶轮,转动90度并径向加速离开风机壳体。
Centrifugal fans or blowers use one of seven types of wheels that are enclosed in a scroll shaped housing. The air enters the fan wheel through the housing inlet, turns 90 degrees and is accelerated radially and exits the fan housing.
轴流风机使用具有两个或多个叶片的螺旋桨,使空气沿轴向移动通过圆柱形外壳或成型孔板。
Axial fans use a propeller, having two or more blades, to move air in an axial direction through a cylindrical housing or formed orifice panel.
术语“风机”用于描述风机或鼓风机。为了做出正确的风机选择,必须考虑风机将面临的以下条件:
• 需要的风量是多少?其额定单位为每分钟空气立方英尺 ( CFM ) 或等效公制立方米每小时 ( M³/Hr )。
• 整个系统的静压阻力是多少?其额定单位为英寸水位 ( in WG ) 或公制等效单位毫米水位 ( mm WG )。
注: WG或mm WG是空气流过管道或管道时产生的流动阻力或摩擦力。确保包括其他设备,如过滤器、阻尼器、热交换器等。
• 通过风机的空气温度是多少?
• 风机外的环境空气温度是多少?
• 气流是洁净、干燥的空气吗?空气中会不会有腐蚀性物质?
• 如果风机将用于输送物料,请确认以下问题
a. 材质是什么?
b. 该材料的重量是多少(磅/立方英尺)?
C. 每分钟或每小时需要输送多少磅?
d. 该材料是长条状还是颗粒状?
• 气流中会有湿气吗?
• 风机运行的海拔高度是多少?
• 是否有任何东西通过风机可能会爆炸?
• 风机运行的位置是否含有任何爆炸性物质、液体或两者兼而有之?
The term “fan” is used to describe either a fan or blower. To make the proper fan selection, you must consider the following conditions the fan will be subjected to:
• What is the air volume that will be required? This is rated in cubic feet of air per minute (CFM) or the metric equivalent, cubic meters per hour (M³/Hr).
• What is the static pressure resistance through the complete system? This is rated in inches water gauge (in WG) or the metric equivalent, millimeters water gauge (mm WG).
Note: in WG or mm WG is the resistance to flow, or friction, caused by the air moving through a pipe or duct. Be sure to include other such as filters, dampers, heat exchangers, etc.
• What is the temperature of the air going through the fan?
• What is the ambient air temperature outside the fan?
• Will the air stream be clean, dry air? Will there be any corrosive substances in the air?
• If the fan will be used to convey material, answer the following:
a. What is the material?
b. How much does the material weigh, in pounds per cubic foot?
c. How many pounds will you need to convey per minute or hour?
d. Is the material long and stringy or granular?
• Will there be any moisture in the air stream?
• What is the altitude where the fan will be operating?
• Is anything going through the fan that could be explosive?
• Does the location the fan will be operating in contain any explosive material, liquid or both?
轴流风机可用于上述所有参数,除非使用风机输送。大多数离心风机可用于上述任何参数。但如果输送物料,则不适合采用前弯(鼠笼)轮的风机。用于输送物料的更佳离心轮类型是径向叶轮。如果要输送的材料又长又粘,例如纸边或纤维,则只能使用开放式径向叶轮。
An Axial fan can be used for all the above parameters, except if you will be using the fan to convey material. Most Centrifugal fans can be used for any of the above parameters. However, if conveying material, a fan with a forward curve (squirrel cage) wheel is not suitable. The best centrifugal wheel type for conveying material is a radial bladed wheel. If the material you will be conveying is long and stringy, like paper trim or fibers, only an open radial bladed wheel should be used.
应用:
虽然工业风机和鼓风机的所有应用列表非常长,但更常见的是:
