我段过去使用的车辆制动软管风水压试压器,由于试压时只能观察到软管靠上面部分的情况,靠水箱底部分的情况无法观察,同时水压试验时保压时间往往达不到要求,因此,多年来软管爆破事故不断发生。为了突破这一关键,我们自行设计制造了一台“转动式自动夹头软管试压器”。自1979年8月份投产使用以来证明,该试压器效果较好。现将其结构、操作方法和特点简述如下。 I used to use the past vehicle brake hose Fengshui pressure test, because the pressure can only be observed when the pressure hose on the upper part of the situation by the tank bottom part of the situation can not be observed, while the pressure test pressure dwell time tends to As a result, hose blasting accidents have taken place over the years. In order to break this key, we designed and manufactured a “rotary automatic chuck hose test pressure.” Since August 1979 put into operation proved that the test pressure better. Now its structure, operation method and characteristic are summarized as follows.
