一些常见的压路机故障及方法
来源：/ 日期：2022-08-24
压路机使用很普遍，但是使用过程中压路机会出现各种各样的问题，影响作业，耽误工期，增加不必要的维修费用。所以我们的操作人员不仅要会使用压路机，还要学会判定一些基础的故障，并进行维修。以下济南路面机械设备厂家给您讲解经常容易出现的几个问题，以及方法，希望会对你有所帮助。
The use of road rollers is very common, but there are various problems in the use of road rollers, which affect the operation, delay the construction period and increase unnecessary maintenance costs. Therefore, our operators should not only be able to use the roller, but also learn to judge some basic faults and carry out maintenance. The following Jinan road machinery equipment manufacturer will explain to you several problems that often occur and the solutions. I hope it will help you.
故障：压路机冒黑烟
Fault: the road roller emits black smoke
方法：检查喷射器是否喷油过多，从而燃烧的不充分，这个时候我们应该进行发动压路机断缸试验。或者看看进气门间隙是否在合理范围内，是不是空气滤芯被堵赛。并且检查一下柴油质量是不是不好。
Solution: check whether the injector injects too much fuel, which leads to insufficient combustion. At this time, we should carry out the cylinder breaking test of the starting roller. Or check whether the clearance of the intake valve is within a reasonable range and whether the air filter element is blocked. And check whether the quality of diesel is bad.
故障：压力不足
Fault: insufficient pressure
方法：压路机油滤清器是否被堵赛，限压阀设定压力过低，必要时限压阀压力。
Solution: whether the oil filter of the road roller is blocked, the set pressure of the pressure limiting valve is too low, and the pressure of the pressure limiting valve is limited when necessary.
故障：怠速不稳熄火
Fault: unstable idling and flameout
方法：液压油路堵塞，请检查在怠速时的体系压力，以及回油滤芯有无堵塞征象。压路机输出功率过低，结合DX数据分析发动压路机的输出情况。
Solution: the hydraulic oil circuit is blocked. Please check the system pressure at idle speed and whether the oil return filter element is blocked. The output power of the roller is too low. Analyze the output of the starting roller in combination with DX data.
故障：压路机起动困难或不能起动
Fault: the roller is difficult to start or cannot start
①发动机温度过低，柴油不易蒸发燃烧。
① The engine temperature is too low, and the diesel is not easy to evaporate and burn.
②喷油器雾化不良
② Poor atomization of fuel injector
③供油时间过晚。
③ The oil supply time is too late.
④供油量过少，混合气过稀。
④ The fuel supply is too small and the mixture is too lean.
⑤气缸漏气量过多，压缩终了不能达到着火温度。
⑤ There is too much air leakage in the cylinder, and the ignition temperature cannot be reached after compression.
It is very important for our operators to learn to master and judge mechanical faults. It is a waste of time to find someone to repair or return to the factory for repair, which will delay the construction period and increase unnecessary costs.
