本文采用发动机系统近似法并进行快速台架磨损试验,在试验中测定零件磨损量,获取工作过程和技术状态各项参数。在诊断参数严重恶化时,更换达到磨损极限的零件,可使工作参数恢复到初始水平。现行的修理制度有必要进行相应的修改,生产部门也应提供相应的技术组织保证和经济上的保证。 In this paper, the engine system approximation and fast bench wear test, measured in the test wear parts, access to the working process and technical parameters of the state. When the diagnostic parameters deteriorate severely, changing the part that reaches the wear limit will return the operating parameters to their original level. The existing repair system is necessary to make the corresponding changes, the production department should also provide the appropriate technical and organizational guarantee and economic assurance.
