我国铁路客车φ406、φ457mm制动缸,解放前已开始装用J型、K型闸瓦问隙自动调整器(以下简称“闸调器”),因其结构简单、作用确实可靠、故障率低,除少部分新造客车装用STI-600型闸调器及盘形制动机装用单向自动调整活塞行程的膜板制动缸者外,大部分客车φ356、φ406mm制动缸仍装用J型闸调器,现占我段配属客车的75%。随着旅客列车编组扩大、运行速度提高、运行里程延长,制动缸活塞行程调整频繁,闸调器已日益不适应运用维修的要求,其主要缺点如下: 1.一次调整量小当制动缸活塞行程超过205mm时,由制动缸内壁φ3mm孔进入闸调器风筒部的压力
China’s railway passenger car φ406, φ457mm brake cylinder, before the liberation has been installed with J-type, K-type brake shoe asked automatically adjust the gap (hereinafter referred to as “gate regulator”), because of its simple structure, the role of reliable, failure rate Low, except for a small part of the new passenger car equipped with STI-600 type brake and disc brake installed with one-way automatic adjustment piston stroke diaphragm brake cylinder, most of the passenger car φ356, φ406mm brake cylinder is still equipped with J-type brake Device, now accounted for 75% of the bus belongs to me. With the expansion of passenger train group, running speed, extended mileage, brake cylinder piston stroke adjustment frequently, the regulator has become increasingly unsuitable for the use of maintenance requirements, the main drawbacks are as follows: 1. A small amount of adjustment when the brake cylinder Piston stroke exceeds 205mm, by the brake cylinder wall φ3mm hole into the regulator Department of the wind tube pressure
