Private intilted air course makes sure the materials in the girding chamber enter into the mill along the inclined plane 独特设计向内倾斜的风道，确保迸入进风窝壳内的物料能顺利地沿着斜面落入磨机内。
Test data show that the pulsating amplitude of secondary air can reach 40 % under some special conditions , affecting more greatly the flame stability 另外，同样结构的风门安装在不同的风道中，将具有不同的流量调节特征。
It suitable for use in wide industrial field or laboratory to measure and controlled the furnace pressure , air flue pressure and air pressure 它可广泛应用于工业领域或实验室进行炉膛压力风道压力空气压力等的测量和控制。
Increasing original resistan coefficient of the secondary air duct can improve the adjusting performance of air damper , and inhibit pulsation of the flow rate 增加二次风道的原始阻力系数，可以使风门的调节特性得到改善并抑制流量脉动。
Drying part : drier including conveyor roller , reduction drive , roller chain , wheel , main wind channel , circle wind channel , exhaust and distributor （三）烘干部分： （干燥机）由输送辊、减速机、托辊链条、链轮、主风道、回风道、排气系统及分配器组成。
Exhaust gas passage with variable pressure : it is adopted to prevent foul air from toilet and kitchen ; check valve is added at the joint 变压式排风：为防止卫生间、厨房排风井内的污风反窜到室内，排风道采用了变压式排气道，并在封到接口处增设了止回阀。
With noise pollution being an important concern , the company has constructed a multiple duct system in the volantor with an expectancy to generate low fan noise 有鉴于噪音污染是大家关切的课题，该公司已为飞行器设计一套多风道系统，希望能降低风扇的噪音。
Parts of damp air are exhausted out off the oven through centrifuge fan and the other is circled and heated still , in this way the purpose can be realized 湿空气从烘盘底下的倾斜风道抽出后，经离心风机使一部分湿空气排出烘箱外。另一部分空气继续循环加热。
Intelligent temperature controller is based microprocessor with pid parameters controlling function . digital display of set and actual temperatures . high temperature controlling accuracy and reliability 热风循环系统由低噪声风机和风道组成，工作室内温度均匀。
Chemical fume hoods shall be of air foil design with 45 degree sloped sections on the sides and top of the hood opening to insure maximum containment and minimum eddying of air currents 化学通风柜应采用风道设计，侧面成45度坡度，罩顶开口，以确保抽气量最大、空气涡流最小。
