轴瓦半圆周长是轴瓦技术要求的一项关键项目,它直接影响装配精度和使用性能。到目前为止,轴瓦半圆周长还无法用通用量具来测量,只有用专用量具来检测。 目前,国内各轴瓦生产厂所使用的轴瓦半圆周长测量仪,大体分机械的,气动的,液压的三种结构形式。其中气动的效率高,对产品能进行百分之百的测量,但有气源压力的不稳定的问题。 一、气源压力变动值的原因分析 引起气源压力的变动因素很多,但主要因素有二个。首先是管道气压的变化。管道
Semi-circular bearing bush is a key technical requirements, which directly affect the assembly accuracy and performance. So far, the semi-circumference of the bush can not be measured with a common gauge, only with special measuring tools to detect. At present, the bearing bush semicircular circumference measuring instrument used in various domestic bush production plants is generally divided into three structural forms of mechanical, pneumatic and hydraulic. Pneumatic high efficiency, the product can be one hundred percent of the measurement, but there is air pressure instability problems. First, the analysis of the causes of pressure changes in gas pressure caused by many factors change, but there are two main factors. The first is the change in pipe pressure. pipeline
