1台YC230型挖掘机工作时,其柴油机突然出现动力不足故障,但失速1 min左右后又恢复正常。检查该柴油机功率,结果在转速为2000r/min时动力不足,如果此时挖掘机继续工作,柴油机会熄火。分析认为,造成此故障的原因可能有以下3点:一是柴油供应不足,二是电控系统故障,三是液压泵功率与柴油机输出功率不匹配。
A Taiwan YC230 excavator work, the sudden failure of its diesel engine power failure, but after about 1 min stall to return to normal. Check the diesel engine power, the result is insufficient power at a speed of 2000r / min, if the excavator to continue working at this time, the diesel engine will stall. Analysis, the cause of the failure may have the following three points: First, the lack of diesel supply, and second, the electronic control system failure, and third, the hydraulic pump power and diesel engine output power does not match.
