(一)概述为了行车安全、正确掌握行车速度,在机车上都装有速度表。速度表显示的准确性将直接影响司机在速度控制上的真实性。为保证速度表的准确性,所以在检修工艺上规定:不经校验的速度表不许装车使用。因而,在能够承担检修速度表的每个机务段都先后配置了机车速度表试验台。但这些试验台至今没有统一的规格,其结构、性能也有很大差别。下面介绍一种我们认为较理想的试验台——XW—79型机车速度表试验台。 (二)XW—79型速度表试验台图1为XW—79型机车速度表试验台的外形。该台是1979年底制成并由贵阳内燃机务
(A) Overview In order to drive safety, correctly grasp the speed, locomotive equipped with a speedometer. Speedometer display accuracy will directly affect the driver’s speed control on the authenticity. To ensure the accuracy of the speedometer, so overhaul on the provisions of: untested speedometer not allowed to load the car to use. Thus, locomotive speedometer test stands were deployed one after another for each locomotive section that can take over the speedometer. But these test benches so far there is no uniform specifications, its structure, performance is also very different. Here is a test we consider a better platform - XW-79 locomotive speedometer test bed. (B) XW-79 speedometer test bench Figure 1 for the XW-79 locomotive speedometer test bench shape. The station was made by the end of 1979 by the internal combustion engine in Guiyang
