目前工程机械上使用的起动机操纵装置,大部分为无保护继电器的电磁式操纵装置。在发动机启动中,不少机械使用人员对此种起动机不能自动断开起动电源,而造成起动机烧毁或损坏而伤脑筋。工程机械使用的ST614型、QD04型起动机,在发动机启动后,起动装置正常工作状况是:松开启动按钮,衔铁在回位弹簧的作用下回位,触盘在触盘弹簧的作用下左移切断启动电源,起动机停止工作。与此同时,拨叉在回位弹簧的作用下,带动单向传动器回位,使起
At present, most of the starter operating devices used in construction machinery are electromagnetic operating devices without protective relays. In the engine startup, many mechanical operators cannot automatically disconnect the starter power from this type of starter, causing the starter to be burned or damaged and intractable. For the ST614 and QD04 starters used in construction machinery, after the engine is started, the normal operating conditions of the starter are: Loosen the start button, and the armature returns under the action of the return spring. The contact plate is left under the action of the contact plate spring. The power supply is switched off and the starter stops working. At the same time, the fork drives the return of the one-way actuator under the action of the return spring.
