根据铁道部的安排,制动软管连接器自动摘解扩大试验已在昆明局开远分局进行,将于1985年内完成。但是,冬季寒冷地区软管连接器实行自动摘解是否可行,尚需进行试验。为此,四方车辆研究所于1985年4月6～10日在齐齐哈尔铁路分局低温试验室作了室内低温软管连接器自动摘解试验。试验温度分为常温、-10～-20℃、-40℃、-45℃、
According to the arrangement of the Ministry of Railways, the brake hose connector automatic digestion and expansion test has been conducted in Kunming Bureau Kaiyuan Branch will be completed in 1985. However, it is still necessary to test the feasibility of automatically extracting hose connectors in cold winter regions. To this end, Sifang Vehicle Research Institute in April 6, 1985 to 10 in the Qiqihar Railway Branch of low temperature laboratory made indoor low temperature hose connector automatic digestion test. The test temperature is divided into room temperature, -10 ~ -20 ℃, -40 ℃, -45 ℃,
