摘要
从系统机构设计、夹紧力分析、液压系统设计和电气控制原理等方面,阐述了水泵试验台液压夹紧装置的设计构造过程.为了保证试验时不发生泄漏现象,在管道联接端面采用抠槽密封处理技术,并对液压夹紧力进行计算与分析,得出在6.4 MPa的压力下,液压夹紧力约为88.238 kN,液压缸提供的最小工作压力为17.563 MPa.现场试验结果表明:与传统法兰联接方式相比,在规定试验压力下,该夹紧装置无泄漏现象,联接端面水力损失减小约0.156%,自动化程度高,水泵出厂检测台数增加约1.5倍,大幅度改善了水泵出厂检测的效率.
The design processes of pump hydraulic fixer from several aspects are presented, such as the design of system structure, the analysis of clamp＇s strength, the design of hydraulic system and the principle of electric control. To ensure no leak phenomenon, the technique of groove and seal is applied in pipe connective part. The results show that hydraulic fixer strength is about 88. 238 kN and the least working pressure is about 17. 563 MPa under the pressure of 6.4 MPa in hydraulic cylinder. Compared with traditional flange alignment, the test results show that the fixer has no leak phenomenon, hydraulic loss on alignment part has declined about 0. 156%, and the number of pump tested in the same time is 1.5 times than before, so it can greatly improve efficiency of pumps＇ testing.
