DGZ-150B型旋喷钻机提升系统稳定性分析及改进
|
摘要
钻机提升系统在开启和关闭时存在着严重的液压冲击现象,因而会造成钻机运行的不平稳。产生液压冲击主要是由换向阀开启和关闭时液压油和负载的动能瞬时转化为压力能而造成的。本文结合DGZ-150B型多管全方位旋喷钻机,主要介绍了通过改进提升液压系统回路和选择合理的提升速度来降低液压冲击的影响。通过利用AMESim软件对改进前后的提升液压系统建模仿真,可以看出改进后的液压系统对液压冲击有明显的控制,系统稳定性大大提高。按照改进后的提升液压系统对钻机的提升系统进行改造,钻机在步进提升时基本感觉不到液压冲击,钻机的震动大大减轻,稳定性增强。
The drilling rig does not run smoothly because of serious hydraulic shock when the hoisting system starts and closes. The main reason of hydraulic shock is that when the reversing valve is opened and closed, the kinetic energy of hydraulic oil and load is converted into pressure energy instantly. In this paper, the impact of hydraulic shock is reduced by improving the circuit of the hoisting hydraulic system and selecting a reasonable lifting speed. Theoretical and AMESim modeling and simulation of the hoisting hydraulic system befero and after improvement indicates that the improved hydraulic system has obvious control over hydraulic shock, and the system stability is greatly improved. After reforming the hoisting system of the drilling rig, hydraulic shock disappeared during stepping up, and vibration of the drilling rig was greatly reduced with stability enhanced.
