一种智能定充型液力偶合器
本技术涉及一种液力偶合器,具体地说是一种定充型液力偶合器,特别是涉及一种可在线实时检测定充型液力偶合器工况且方便液力偶合器拆卸或安装的智能定充型液力偶合器。
技术介绍
定充型(限矩型、普通型)液力偶合器因其具有其他传动方式所不具备的特性而被广泛应用。由于定充型液力偶合器是个封闭的传动元件,其运转工作时是不可能对其充液量进行调节的。在当定充型液力偶合器遇到工作机严重过载时会降低输出转速直至堵转(输出零传速)对整个传动系统实现限矩保护,并在长时间过载时随着其内部工作介质温度与压力上升,将通过易熔安全塞将工作介质喷泄出去,从而切断传动实现对整机的卸荷保护,或通过特制的防喷安全塞产生动作触发电器元件给出信号实现断电保护与声光报警。作为定充型液力偶合器对整机的过载终极保护,无论是通过安全塞喷液还是采用防喷安全塞都存在不足:当采用易熔安全塞喷液保护时,喷出的工作介质对现场环境有一定污染,且高温液体可能对周围人员造成伤害,恢复液力偶合器的运行必须重新充液和更换安全塞,操作比较麻烦;而采用防喷安全塞虽可避免工作介质的喷出,但因其动作温度设置较低(防喷安全塞必须与易熔安全塞配套使用,防喷安全塞的动作温度远低于易熔安全塞的熔喷温度)而会使工作机的过载能力大为下降,同样也必须更换防喷安全塞才能恢复液力偶合器的运行。特别要提到的是,当主机因故断电短时又恢复供电,诸如斜坡带式输送机、斗式提升机等类设备可能在皮带料斗已作下行时立刻切换至工作拖动状态,会使液力偶合器同时从输入、输出端吸收能量而导致内部工作介质的温度与压力急剧上升,在安全塞尚来不及动作时引起液力 ...
