1台STL1000C型塔式起重机配置的卡特C15型电控柴油机连续出现2起启动故障,本文结合该柴油机启动电路工作原理,对启动电路故障进行排查。一、启动电路工作原理卡特C15型电控柴油机启动电路主要由蓄电池G、蓄电池负极开关S10、启动机M1、点火开关S1、急停按钮S2、维修按钮S3、启动继电器K1等组成。启动电路的外围设备有柴油机监视器MON、电源继电器K2、熔断器(QF1、QF2、QF3、QF4)、燃油液位开关SL1、冷却液位开
A set of STL1000C-type tower crane Caterpillar C15-type diesel engine control continuous emergence of 2 start-up failure, combined with the diesel engine start-up circuit works to troubleshoot the start-up circuit. First, the starting circuit works Caterpillar C15-type diesel engine starting circuit mainly by the battery G, battery negative switch S10, starter M1, ignition switch S1, emergency stop button S2, repair button S3, the relay K1 and other components. Peripheral equipment to start the circuit are the diesel monitor MON, power relay K2, fuses (QF1, QF2, QF3, QF4), fuel level switch SL1, coolant level ON
