每逢夏季,随着环境温度升高及现场作业中粉尘量增大的影响,给露天作业中的装载机、推土机、潜孔钻、挖掘机等工程机械的使用带来许多困难,如以柴油机为动力源的装载机、推土机、空压机等设备,其“心脏”部件柴油机,由于温度的升高使润滑油的粘度下降,润滑性能下降,致使动力不足,其内部机件往往也容易发生磨损,密封件损伤,进一步影响设备使用性能;而以电动机为动力源的挖掘机、潜孔钻等设备出现润滑管道堵塞,造成零部件润滑不良,影响设备使用寿命;因粉尘清扫不及时落入液压系统,加剧零部件磨损,影响设备使用寿命。
Every summer, with the increase of ambient temperature and the increase of the amount of dust in field work, it brings many difficulties to the use of construction machinery such as loaders, bulldozers, down-hole drills and excavators in open-air operations. For example, diesel engines As the power source of loaders, bulldozers, air compressors and other equipment, the “heart” parts of the diesel engine, as the temperature increases the viscosity of lubricating oil decreased, decreased lubrication, resulting in lack of power, the internal parts are often prone to Wear and seal damage, further affect the equipment performance; and motor-powered excavators, DTH drilling and other equipment blockage of the lubrication pipe, resulting in poor lubrication of parts, affecting the service life of the equipment; dust does not fall timely due to fall into Hydraulic system, aggravating parts wear and tear, affecting the service life of equipment.
