在工程机械的使用中,机械的电气工程系统的故障率是比较高的,这是因为工程机械工作的环境比较恶劣,泥沙、潮湿环境、载荷变化等都有可能导致电气工程故障,所以,在日常的设备管理中要从维护维修和管理两个层面来进行控制,降低故障率。 In the use of construction machinery, machinery electrical engineering system failure rate is relatively high, this is because the construction machinery working environment is harsh, sediment, humid environment, load changes are likely to lead to electrical engineering problems, therefore, In the daily equipment management from the maintenance and management of two aspects to control and reduce the failure rate.
