1.前言液压传动系统工作得好坏,主要体现在执行机构上。执行机构动作是否正常,将直接影响到该系统所服务机构的正常工作。我厂连铸机的中间罐小车(下简称“中间车”)上、中间罐的升降,横移动作全靠液压传动系统来控制。这套液压系统执行机构常出现的故障有油缸下滑,升、降速度过快或过慢等。其中油缸下滑故障最为严重,它使中间罐无法上、下移动,出钢水口无法调节,直接影响连铸生产。必须尽快处理故障,保证生产的正常进行。参照图1,对液压系统的下滑故障进行如下分
1. Introduction Hydraulic transmission system works well or bad, mainly reflected in the implementing agencies. The normal operation of the implementing agencies will directly affect the normal work of the agencies served by the system. I plant the middle of the caster car (hereinafter referred to as the “middle car”), the middle of the tank movements, the whole move by hydraulic transmission system to control. The hydraulic system actuator failures often have the cylinder down, up, down too fast or too slow and so on. Including the most serious tank down failure, which makes the middle tank can not move up and down, tapping nozzle can not be adjusted directly affect the continuous casting production. The failure must be dealt with as soon as possible to ensure the normal production. Referring to FIG. 1, the slip failure of the hydraulic system is divided as follows
