什么是发动机预防性维护?
所有的发动机如果保养不好，都容易出故障. Prioritizing engine maintenance is the responsible thing to do as an equipment owner. 这也是一个明智的做法作为一个企业的所有者.
你对设备的引擎保养得越好，它就能为你服务得越久. 发动机处于工作状态的时间越长, the greater return on investment you’ll get as it continues to work at peak performance and make you money.
使您的重型设备具有高性能和长寿命, 你需要对发动机进行适当的预防性维护. Preventive maintenance is maintenance or service that’s performed regularly to prevent equipment failure. Equipment owners conduct preventive maintenance to avoid sudden and unexpected work interruptions due to breakdowns. Preventive maintenance can also help you save on long-term maintenance and repair costs by minimizing the level of damage.
Preventive engine maintenance is especially important since engine failures are expensive to fix and can cause long work stoppages. Equipment owners conduct preventive engine maintenance based on usage or service hours. Equipment manufacturers recommend specific servicing intervals to maintain peak operating performance. 作为Cat®设备拥有者, it’s important to know what the manufacturer’s preventive maintenance recommendations are. Your Operation and Maintenance Manual will tell you what type of maintenance to conduct for your engine and how often. 与有经验的技术人员一起工作也会有所帮助.
这里是一些类别 预防发动机维修 that equipment owners should perform routinely as prescribed by the manufacturer:
