去年11月,我到长沙参加了日本活塞环公司技术部长胜芳男等五人来华技术交流活动。从日方所介绍的一些情况,本人感到有几个问题对我国活塞环行业当前挖潜、革新、改造是有一定的参考价值,特提出个人的一些粗浅看法,供大家来讨论。 一、解决当前活塞环使用寿命及“短线”问题必须从扩大镀铬环的生产能力入手 我国现有七、八十个厂家在生产活塞环,而活塞环仍是一个“短线”产品,这不只是因我国活塞环行业生产工艺落后,生产效率低,更主要的是质量不够满意,使用寿命不高,因而耗损量大。
Last November, I went to Changsha to participate in the technical exchange activities of five people from Japan’s Piston Ring company, including Sheng Fangnan, and others. From some of the situations introduced by the Japanese side, I feel that there are several issues that have certain reference value for the current potential of the piston ring industry in China, innovation, and transformation. I personally provide some superficial views for everyone to discuss. First, to solve the current life of the piston ring and the “short-term” problem must start from the expansion of the production capacity of chrome-plated ring. China’s existing seven or eighty manufacturers in the production of piston rings, while the piston ring is still a “short-term” product, which is not just Due to the backward production technology of the piston ring industry in our country and the low production efficiency, the main reason is that the quality is not satisfactory and the service life is not high, resulting in a large amount of wear.
