摘　　要：液压传动是利用密闭系统中的受压液体来传递运动和动力的一种传动方式。它有着许多优点,所以在机械中被广泛应用。济宁三号煤矿副井操车系统就采用液压控制,并对原来的普通液压调速回路进行改进,从而解决了推车机因过载而产生的液压冲击爆管的难题,满足了推车机快速启动,工作慢进,快速退回的工作要求。Hydraulic transmission is a transmission mode to transmit motion and power by pressurized fluid in a closed system. It has many advantages,so widely used in the machinery. Jining no. 3 coal mine car during operating system adopts hydraulic control,and to improve the original ordinary hydraulic speed control circuit,which solves the pusher is caused by overload problem of hydraulic shock tube,satisfy the pusher is quick start,slowly into the work,quickly returned to the job requirements.

关 键 词：操车系统 液压 调速
