单双蓄能器供油的提升机恒减速闸控系统动态特性对比

提升机恒减速闸控系统是矿井提升机安全制动的关键设备,蓄能器作为提升机恒减速闸控系统安全制动时的唯一动力源,其动态性能直接影响恒减速制动的动态响应,进一步影响提升机的运行安全。传统的单蓄能器供油的恒减速闸控系统具有惯性大、响应时间长等问题,基于此,本文在不改变蓄能器总容积的前提下,提出用双蓄能器供油代替单蓄能器供油的解决方案,并利用AMESim仿真软件对单蓄能器、双蓄能器供油的恒减速闸控系统进行仿真分析。仿真结果表明:采用双蓄能器,可有效缩短提升机恒减速制动的响应时间,提高恒减速制动的稳定性。

Dynamic Characteristics Comparison of Hoist Constant Deceleration Brake Control System with Single and Double Accumulators

The hoist constant deceleration brake control system is the key equipment of mine hoist safe braking. Accumulator is the only power source when hoist constant deceleration brake control system implements safe braking. Its dynamic performance directly affects the dynamic response of constant deceleration braking, and further affects the operation safety of hoist. The traditional constant deceleration brake control system with single accumulator is characterized by large inertia and long response time. Based on this problem, this paper proposes a solution to replace single accumulator with double accumulator without changing the total volume of accumulator. The constant deceleration brake control system with single and double accumulator is simulated by AMESim software. The simulation analysis is carried out. The simulation results show that the double accumulator can effectively shorten the response time of hoist constant deceleration braking and improve the stability of constant deceleration braking.
