最近,英国铁路及欧州大陆铁路开始试用一种不用热源的水平风幕式道岔除雪装置。据称这种道岔除雪装置几年前已在加拿大和美国铁路上开始使用。该装置可在室外环境温度下用160公里/小时(45米/秒)速度的强大气流直接向道岔的工作部位喷吹,以清除道岔区的积雪。目前使用的各种加热型道岔除雪器可使道岔区的积雪融化或蒸发,除雪效果较好;但相对来讲,这类加热型道岔融雪器的能量刊用率较低,并且燃料的消耗量也较大,同时还经常
Recently, the British Railways and the European Continental Railroad started to try out a type of horizontal curtain curtain switch snow removal device without heat source. The switch de-icing device is said to have been in use on Canadian and U.S. railways a few years ago. The unit blows directly into the working part of the switch at a strong ambient air velocity of 160 km / h (45 m / s) at outdoor ambient temperatures to clear snow in the turnout area. The current use of various types of heated switch snow melts can make the snow melted or evaporated in the turnout area, and the effect of snow removal is better. However, the energy usage rate of such heated switch type snow melters is relatively low, and the fuel consumption The amount is also large, but also often
