基于MCGS物料悬浮速度试验台控制系统设计
|
摘要
物料悬浮速度是清选装置与气力输送设备研发的重要设计参数,针对目前物料悬浮速度试验台存在自动化水平低、操作繁琐、检测精度差等问题,设计基于MCGS物料悬浮速度试验台。通过该试验台进行多种物料的悬浮速度测定试验以及与传统试验台的对比试验。试验结果表明:该试验台悬浮速度测定结果相对误差<3.0%,测试结果准确,满足物料悬浮速度的测试要求。
Grain suspension speed is an important design parameter for the research and development of cleaning equipment and pneumatic conveying equipment. Aiming at the problems of low level of automation, complicated operation and poor detection accuracy of grain suspension speed test bench, the MCGS-based material suspension speed test bench was designed. Through the test bench, the suspension speed measurement test of various materials and the comparison test with the traditional one were carried out. The test results show that the relative error of the test benches less than 3.0%, and the test results are accurate, which fully meets the test requirements of grain suspension speed.
