现在客车车底水箱上的滤尘器(KT178·3507.00)是老型车沿袭下来的。原来装滤尘器的目的,是考虑在没有自来水设施的站段上水时,防止杂质进入水箱堵塞给水管路及阀门而设置的。现在看来我国铁路站段都有自来水设施,所以,装滤尘器已无必要,建议取消。取消后可减轻车辆自重,节约有色金属并降低制造成本。
Now the dust filter (KT178 · 3507.00) on the bottom tank of the passenger car is followed by the old car. The purpose of the original installation of dust filters is to consider the station without water facilities, water, to prevent impurities into the water tank to block the water supply pipes and valves set. It now appears that China’s railway station has tap water facilities, therefore, installed dust filter is no longer necessary, it is recommended to cancel. After the cancellation can reduce the weight of vehicles, saving non-ferrous metals and reduce manufacturing costs.
