读了《起重运输机械》一九八六年第四期刊登的“叉车货叉下滑量及门架自倾角与换向阀内漏的关系”一文很受启发。该文作者通过分析多路换向阀的内部泄漏规律建立货叉下滑量及自倾角的定量关系,这对深化叉车有关整机性能的研究,无疑是有益的。但文中尚有一些不尽全面之处,提出来和广大讨论。 Read “Crane Transport” published in the fourth issue of 1986, “Fork lift forklift and gantry self-inclination angle and the relationship between the drain valve,” a very inspired article. The author through the analysis of the multi-way valve internal leakage rule to establish the quantitative relationship between fork slip and self-inclination angle, which deepen the forklift on the machine performance is undoubtedly beneficial. However, there are still some incomplete articles in the article which are put forward and discussed extensively.
