SGW—150型采煤机牵引部恒功率调速伺服系统性能分析

THE PERFORMANCE ANALYSIS FOR THE HYDRAULIC SERVO-SYSTEM OF HAULAGE PARTY FOR SGW-150 SHEARER WITH CONSTANT POWER SPEED GOVERING

本文对四川省科委“七·五”重点课题“极薄煤层采煤机械化”中的SGW—150型采煤机牵引部液压恒功率调速伺服系统进行了动态性能分析,分析结果表明作者们所设计的系统对于SGW—150型采煤机是稳定的而且是合理的。

The mechanization of mining thinnest coal seam is a key program in the 7th five-year plan in Sichaan province, It is sponsored by The Scientific and Technieal Commission of Sichuan province. In this paper, the dynamic performance for the hydraulie servo-system of haulage party for SGW-150 shearer with coustant-power speed governing is analysed. It shows that the system designed by us is stability and reasonable for SGW-150 shearer.
