桂塞付、出油伐严密度试验台<图号:三标机7411>,是我处設計人员遵照毛主席指引的設計革命的道路,在山海关內燃机务段进行“三结合”现场設計的成果。於1970年9月试制成功。投入运用几个月来,情况更好。本试验台系在南口机車車辆机械厂同名试验台基础上,針对机务段检修作业特点和立足於机务段能夠自力更生制作的条件,进行了改进設計。保留了南口厂试验台液压传动,自动化程度高的优点,提高了效率,简化了结构,降低了成本。本试验台,桂塞付严密度試验部分,探用定压试验的原理,这种方法,比較变压试
Gui Sai pay, the oil cutting strict test stand , is my design staff to follow the direction of Chairman Mao’s design revolution road, in the Shanhaiguan internal combustion engine section “three combination” on-site design results . In 1970 September trial success. Put into operation for several months, the situation is better. Based on the test bed of the same name of Nankou Locomotive and Rolling Stock Machinery Factory, this test bench is designed for the improvement of locomotive maintenance operations and the conditions for self-reliant production in the locomotive depot. Nankou retained the hydraulic test bed test station, the advantages of a high degree of automation to improve efficiency, simplify the structure and reduce costs. The test bench, Gui plug pay the tightness test part, probing the principle of constant pressure test, this method, comparing the transformer test
