内燃机车的工作可靠性,是由衡量设计、制造水平的固有可靠性和反映操作、保养、检修等使用条件影响固有可靠性的运用可靠性两部分组成。本文通过对进口的ND_4型和国产的东风_4型内燃机车运用可靠性的分析比较,阐明在内燃机车的工作可靠性、耐久性(使用寿命)、经济性(先进的经济技术指标)中,目前可靠性仍是第一位的,要从运用可靠性的实际出发,统筹考虑内燃机车的设计制造、运用保养、日常检修的综合经济技术指标。在继续重视研究改进内燃机车固有可靠性进行治本的同时,必须花大力下本钱把机车的运用保养、日常检修水平搞上去,促进运用可靠性,从而进一步提高内燃机车的工作可靠性。
The reliability of a diesel locomotive is composed of two parts: the inherent reliability of the design and manufacturing level and the reliability of operation that affect the inherent reliability by reflecting the operating conditions such as operation, maintenance and overhaul. This paper analyzes and compares the reliability of the imported ND_4 and domestic Dongfeng _4 diesel locomotive to clarify that in the reliability, durability (service life), economy (advanced economic and technical indicators) of diesel locomotives, At present, reliability is still the top priority. From the practical application of reliability, we should consider the comprehensive economic and technical indicators of design, manufacture, maintenance and routine maintenance of diesel locomotives. While continuing to attach great importance to improving the inherent reliability of diesel locomotives, we must make great efforts to capitalize on the maintenance and routine maintenance of locomotives, and promote the application of reliability so as to further improve the operational reliability of diesel locomotives.
