采用含磷闸瓦可以解决内燃机车闸瓦火花引起的着火问题。 内燃机车铸铁闸瓦火花引起机车底架残油着火是铁路上长期存在的一个问题。这个问题虽可用防止漏油和经常擦去残油的方法加以防止,但更基本的途径是防止火花的产生。这就是采用别的材料代替铸铁制成闸瓦,对铸铁进行改善,使之既能减少火花,又不影响其它性能。 两年前,英国阿尔布莱特·威尔逊公司提出一种新型磷铁合金,它的特性之一是用 The phosphorus-containing brake shoe can solve the ignition problem caused by the brake spark of the diesel locomotive. Diesel locomotive cast iron brake sparks caused locomotive chassis residual fuel on fire is a long-standing problem on the railway. Although this problem can be prevented by the method of preventing oil spills and often wiping residual oil, the more basic approach is to prevent the generation of sparks. This is the use of other materials instead of cast iron brake shoe, cast iron to improve, so that it can both reduce the spark, without affecting other properties. Two years ago, the British company Albright Wilson proposed a new type of phosphorus-iron alloy, one of its characteristics is the use of
