We have talked a lot about excavator knowledge, whether small series or friends have learned a lot of knowledge, today we will review some of the excavator accessories related knowledge.

　　我们都知道，一个好的设备有很多配件，那么你了解配件的使用以及如何处理问题吗?现在让我们来看看。

　　As we all know, a good equipment has many accessories, so do you know how to use accessories and how to deal with problems? Now let's take a look.

　　绞盘漏油

　　Winch Oil Leakage

　　在挖掘机配件施工中，钢丝绳绞盘发生漏油事故。拔完所有的钢丝绳后，发现液压油从绞盘的螺栓中渗出，当油门加大时，泄漏速度加快，怠速时几乎没有漏油。初步分析可能是由于螺栓松动或垫片损坏造成的，但在更换垫片并拧紧螺栓后，经试验仍存在失效。通过对液压原理图的进一步分析表明，其原因可能是回油差、背压大。所以绞盘回油控制阀的替换,也就是说,在里面的油舱的上部短焊接回油管道,更换回油管道是厚的比原来的机器,这样回油管道的结束不是连接到控制阀,并直接连接到新的回油管道,为了减少回油背压,再试一次,故障消失了。

　　In the construction of excavator fittings, oil leakage accident occurred in steel wire rope winch. After pulling out all the wire ropes, it is found that hydraulic oil seeps out from the bolts of the winch. When the throttle increases, the leakage speed accelerates, and there is almost no oil leakage at idle speed. Preliminary analysis may be due to bolt loosening or gasket damage, but after replacing the gasket and tightening the bolt, there is still failure after testing. Further analysis of the hydraulic schematic diagram shows that the reason may be the difference of oil return and the high back pressure. So the replacement of winch return control valve, that is to say, the short welded return pipeline in the upper part of the oil tank inside, replacing the return pipeline is thicker than the original machine, so that the end of the return pipeline is not connected to the control valve, and directly connected to the new return pipeline, in order to reduce the back pressure of return oil, try again, the fault disappeared.

　　引擎发动不起来了

　　The engine won't start.

　　油过滤器的滤芯被阻塞或燃料管道被阻塞。在这种情况下，挖掘机配件的燃油滤清器应清洗或更换，同时清洗燃油管路。气缸里有燃料。检查柴油机油箱的油位。如果燃料不足，可以添加燃料，清洗喷嘴或更换新的喷嘴。

　　The filter element of the oil filter is blocked or the fuel pipeline is blocked. In this case, the fuel filter of excavator fittings should be cleaned or replaced, and the fuel pipeline should be cleaned at the same time. There is fuel in the cylinder. Check the oil level of the fuel tank of the diesel engine. If fuel is insufficient, fuel can be added, nozzles can be cleaned or new nozzles can be replaced.
