我厂的三结合革新小组于1972年7月,仅用两个月时间成功地革新成一套发动机冷磨热试试验台(图1)。全套试验台的特点是在大修时试验发动机所需用的汽油、润滑油、冷却水、电源,全部通过地沟内的管道供给,而冷却水和润滑油实现了自动循环。发动机热磨试验时排出的废气也通过地沟内的管道排出室外。此外,用硅整流器把交流电变成直流电,代替了蓄电池。 In July 1972, the three-in-one innovation team of our factory successfully transformed into a set of engine cold mill thermal test bench (Figure 1) in just two months. The complete set of test rigs features petrol, lubricant, cooling water, and power, all of which are required to test the engine during overhauls, all supplied through ducts in the trench, while cooling water and lubricants automatically cycle. Exhaust gases from the engine hot mill test are also vented through pipes in the trench. In addition, the use of silicon rectifier to AC into DC, instead of the battery.
