排烟罩的排风管的区别
编辑:淄博金冠厨房设备有限公司   时间:2017-12-01

目前还能够选用扁椭圆形风管来下降风管的占用空间高度,排烟罩扁椭圆形风管是将螺旋风管用特殊的设备将圆形风管经撑拉定型加工成扁椭圆形。
  At present, a flat elliptical wind pipe can be adopted to reduce the occupied space height of the air pipe, and the flat elliptical wind pipe is a special device for the spiral wind, and the circular wind pipe is processed into a flat ellipse through the stretching and drawing and shaping.
  螺旋风管的制作高度自动化,出产速度很快,一般的风管每分钟能出产20~40米,因为其原材料镀锌带钢与整张镀锌钢板比较,价格较低,加上其工厂化出产和标准的标准化,使得螺旋风管的造价要比矩形风管低;别的因为其支、吊架需量少,装置工作量少,所以螺旋风管的总成本较低
  The spiral wind pipe manufacturing is highly automated, faster production, general air pipe per minute can produce 20 to 40 meters, because of its raw materials compared to galvanized steel and galvanized steel sheet, the price is low, the factory production specifications and standard plus, makes the spiral duct cost to pipe lower than the rectangular wind; also because of the support and hanger needs less installation work less, so the total cost of the lower spiral duct
  排烟罩螺旋风管的密封性好,走漏量小,经过对各种系列压力的测验,螺旋风管管段自身能够做到不走漏,这是矩形风管无法做到的。
  The spiral wind pipe has good tightness and little leakage. Through the test of various series of pressure, the spiral pipe section can not leak, this is the rectangular wind pipe can not do.

  矩形风管因为收到钢板尺寸的约束,每两米就需求设置一对法兰,而法兰衔接处是最简单走漏的。螺旋风管的长度能够依据用户的需求设定,削减风管的衔接,削减走漏点。
  Due to the limitation of the dimension of the steel plate, a pair of flanges should be set up every two meters, and the flange joint is the easiest to leak. The length of the spiral wind pipe can be set according to the needs of the user, thereby reducing the connection of the wind pipe and reducing the leakage point.
  并且螺旋风管能够选用无法兰衔接,这样走漏量更少,走漏量的削减使日常运转费用和能源消耗下降。
  Furthermore, the spiral air duct can be made of no blue connection, thus reducing the leakage rate and reducing the daily operating cost and energy consumption.
  因为矩形风管的四角易产生湍流,削减了有用通流面积,螺旋风管的空气流动性好,有用通流面积大,所以螺旋风管的二次噪声小,排烟罩因为螺旋风管的强度大,因此风管振荡引起的低频噪声更小,空气流动性能好,体系压降小,日常运转体系耗电量少。
  The four corners of a rectangular duct is easy to produce turbulence, reducing the effective flow area, the spiral air flow duct, the effective flow area is large, so the spiral duct two low noise, due to spiral wind strength, so the wind pipe smaller low frequency noise caused by vibration, air flow performance well, the system pressure drop small, daily operation of system power consumption.
