随着人们生活水平的不断提高,办公场所环境的不断改善,空调系统也越来越广泛地深人到日常生活和工作中。
With the continuous improvement of people's living standards and the continuous improvement of the environment of the office, the air conditioning system is becoming more and more extensive to the daily life and work.
除具有刚度好、强度大的优点外,又具有吸音降噪、保温隔热不需要二次保温的性能,克服了以前复合风管强度弱,外壁易破损的弱点,发扬了镀锌铁皮的优势,使用寿命更长,且美观大方,更显尊贵本色。
Besides having good rigidity, large strength advantages, but also has the heat insulation, sound absorption and noise reduction does not require two insulation performance, to overcome the previous composite wind pipe strength is weak, easy to damage the wall weakness, carry forward the advantages of galvanized iron, longer service life, and beautiful appearance, more noble qualities.
铁皮风管在制作时,其所用板材、型材以及其他主要成品材料制作要求十分严格。焊缝应作外观检查,不应有气孔、砂眼、夹渣、裂纹等缺陷,焊接后钢板的变形应矫正。风管水力计算方法主要有三种。

When the iron pipe is made, the requirements for making plates, profiles and other main products are very strict. The weld shall be for visual inspection, should not have stomata, sand hole, inclusion and crack of steel plate after welding, deformation should be corrected. There are three main hydraulic calculation methods for wind pipe.
(1)假定流速法:该方法先按技术经挤要求选定风管的流速,再根据风量来确定风管的断面尺寸和压力损失,目前常用此法进行水力计算。
(1) assuming the velocity method: the method first selects the flow rate of the wind pipe according to the requirement of technology extrusion, and then determines the section size and pressure loss of the wind pipe according to the air volume. At present, this method is usually used for hydraulic calculation.
(2)压损平均法:该方法是将已知总作用压头按下管长度平均分配给每一管段,再根据每一管段的风量确定风管断面尺寸。如果风管系统所用的风机压头已定,或对分主管路进行阻力平衡计算 ,此法较为方便。
(2) pressure loss average method: this method assigns the known total acting pressure head to the length of each pipe evenly, and then determines the size of the pipe section according to the air volume of each pipe section. This method is more convenient if the fan pressure head used in the wind pipe system is fixed or the resistance balance of the main pipe is calculated.
(3)静压复得法:该方法是利用风管分支处复得的静压来克服该管段的阻力,根据这一原则确定风管的断面尺寸。此法适用于高速空调系统的水力计算 。
(3) the static regain method: this method is the use of static pressure air pipe branch complex to overcome the resistance of the pipe section, according to the principle of determining the section size of the wind pipe. This method is suitable for hydraulic calculation of high speed air conditioning system.
