【摘要】 液力偶合器作为近似软启动装置 ,最主要的特征就是对电动机有过载保护 ,然而在刮板输送机的实际应用中 ,有时会出现烧毁电机 ,保护不了电机的现象 ,甚至有时连负载都启动不了 ,这在工程上将会造成很严重的后果。通过分析将有助于解决实际问题。更多还原

【Abstract】 The appliance of coincidence has a important characteristic with the over loading_protect when it look as the equipment of weak_startup.However on practice with transport,owing to the appliance of coincidence,the electromotor can burned and not protect the electromotor sometime.Evermore,the load can not start.It bring the graveness aftereffect in engineering.So the paper will solve the problem through the analysis.更多还原
