针对目前双螺杆榨油机冷榨技术的理论和实验研究中存在的一些问题,以SSYZ120/12双螺杆榨油机为研究对象设计出一种双螺杆榨油机膛内压力测试系统。通过在SSYZ120/12双螺杆榨油机榨条上开孔安装高温熔体压力传感器测得膛内压力,同时采用电阻应变片电测法,根据粘贴在榨条外表面上的电阻应变片输出的应变数据,计算出膛内压力。选用油菜籽和花生仁进行压榨实验,将两种方法测得的结果进行对比分析,能较好地反映出榨油机膛内的压力分布情况,两种方法所得结果的相对误差分别是18.85%、11.52%。此测试系统有助于螺杆榨油机压榨过程的理论研究。

Aiming at some present problems existing in the theory and experimental research on cold pressing technology of twin- screw press,a kind of chamber pressure test system of twin- screw press was designed with SSYZ120 /12 twin- screw press as research object. The chamber pressure was determined by a high- temperature melt pressure sensor installed in a hole opening on the cage bar of SSYZ120 /12 twin- screw press,and according to the strain data output through electric resistance strain gauge pasted onto the outer surface of the cage bar,the chamber pressure was calculated using electric resista...
