官厅水库输水道进水塔的上部是钢筋混凝土的框架。为了防止冰凌对建筑物的挤压及保护拦污栅钢梁起见,必须采取相应的有效措施。 1955年经过几次的摸索、研究,试验成功了“压缩空气吹风”的办法。现将安装、操作的方法,介绍于下。利用原有的一台旋转式的小空气压缩机。它用7(1/2)匹马力,220伏特,1,440转/分的交流电动机来带动。用2吋直径的铁管与空气压缩机相接作为送风管;用2条1(1/2)寸直径的戮管作入水风管,胶管下端各装2公尺长1吋直径的鉄管作为风嘴,并能起重锤作用。
The upper part of Guanting Reservoir water inlet tower is the frame of reinforced concrete. In order to prevent ice squeezing the building and trash rack to protect steel beams, must take appropriate and effective measures. In 1955 after several groping, research, test the successful “compressed air hair” approach. Now the installation, operation method, introduced in the next. Use of a rotating small air compressor. It drives with 7 (1/2) horsepower, 220 volts, 1,440 rpm AC motors. A 2 “diameter iron pipe is connected to the air compressor as a supply air duct. Two 1” (1/2 “) diameter pipes are used as water supply ducts. Each pipe is fitted with a 2” long 1 "diameter pipe As a tuyere, and can play a hammer role.
