    冷却塔是一种将循环冷却水在塔体内喷淋到填料上,使之与空气直接接触,通过蒸发和对流把携带的热量散发到大气中去的冷却装置。它的运转有以下需要注意的:
  1、减速机应经常检查油标油位,润滑油推荐用22~28号双曲线齿轮油或90~120号工业齿轮油,夏季用粘度大的油。第一次运转20天后将油排空,换新油。
  2、风机、电机、减速机运转前须按相应产品说明书检查,特别是电机接线,应按电机厂提供的接线图接线,有时各方表示不一致,易造成接线错误。符合要求后再启动,启动顺序,由低速到高速。叶片角度按样本规定数值安装后,如高速运转电流超过额定值,应立即停机,速与厂家联系。调整风机叶片角度符合要求的标准是:A、在各风机叶片距风筒150mm处的上下缘划线得到上点和下点的高差Δh值,每个叶片的Δh值最大与最小之差不得大于2mm;B、距风筒150mm处叶片上缘的标高值,每个叶片标高值最大与最小之差值不得大于0.002R(R为风机半径);C、电机的电流在高速运转时等于额定值的0.9~0.95。
  3、如循环水、补充水水质差时应采取水质稳定措施,设旁滤器,必要时须采取杀菌灭藻措施。
  4、玻璃钢属燃烧体,因此冷却塔在维修时不得动用明火,如动用明火则必须采取相应安全措施,并且必须经过消防、安全部门批准,有专职消防人员、消防设施在场。
