挖掘机配件手柄操作费力缘由何起

日期:2021-08-16   来源:http://www.dybocheng.com
对于挖掘机来讲,只有通过对挖掘机配件手柄进行操作才可以完成一系列的工作,因此手柄无疑是非常重要的一款挖掘机配件,若是在操作手柄的时候,发现手柄出现了操作费力的现象,那么大家就需要小心了,因为正常来讲挖掘机配件手柄的操作是毫不费力的,下面来了解一下原因。
For excavators, a series of work can be completed only by operating the handle of excavator accessories. Therefore, the handle is undoubtedly a very important excavator accessory. If you find that the handle is laborious when operating the handle, you need to be careful, because normally, the operation of the handle of excavator accessories is effortless, Here's why.
挖掘机操作手柄总成分为两大部分,上面部分是操作杆,下半部分是操作先导阀,拨开手柄的外层护罩就可以看到顶端有四个柱塞被盖着
The operating handle of the excavator is composed of two parts. The upper part is the operating lever and the lower part is the operating pilot valve. When the outer cover of the handle is removed, you can see that there are four plungers covered at the top

一、挖掘机配件操作手柄
1、 Excavator accessories operating handle
挖掘机操作手柄总成分为两大部分,上面部分是操作杆,下半部分是操作先导阀,拨开手柄的外层护罩就可以看到顶端有四个柱塞被盖着,中间是个万向节,底部连接着六根液压管,分别是1根进油管、1根回油管和4根先导油管,进油管接头位置一般都会安装一个小的过滤网,我们需要定期的进行清理,防止进油油路被堵塞。
The operating handle of the excavator is composed of two parts, the upper part is the operating rod, and the lower part is the operating pilot valve. When you remove the outer shield of the handle, you can see that there are four plungers covered at the top, a universal joint in the middle, and six hydraulic pipes connected at the bottom, including one oil inlet pipe, one oil return pipe and four pilot oil pipes, A small filter screen is usually installed at the joint of the oil inlet pipe. We need to clean it regularly to prevent the oil inlet from being blocked.
挖掘机配件手柄由于品牌的不同,有的用户刚刚操作的时候会觉得很不习惯,感觉手柄很重以为是出现了故障问题
Due to different brands of excavator accessories handles, some users feel very uncomfortable when they first operate. They feel that the handles are heavy and think there is a problem
二、手柄的操作过重故障
2、 Excessive operation of handle fault
挖掘机配件手柄由于品牌的不同,有的用户刚刚操作的时候会觉得很不习惯,感觉手柄很重以为是出现了故障问题,其实并不是机器出问题了,而是个人在使用习惯上的一种错觉。我们在使用不熟悉的机器的时候,可以先调节一下手柄的长度,然后先不启动的试一试感觉,看使用效果,如果是真的有很明显的沉重现象,就需要检查是不是先导阀压力过大引起的,或者看先导油路过滤网是否通畅。
Due to different brands of excavator accessories handle, some users feel very uncomfortable when they first operate. They feel that the handle is heavy and think there is a problem. In fact, it is not a problem with the machine, but an illusion of personal use habits. When using unfamiliar machines, we can first adjust the length of the handle, and then try to feel it without starting it to see the use effect. If there is an obvious heavy phenomenon, we need to check whether it is caused by excessive pressure of the pilot valve, or whether the filter screen of the oil passage is unobstructed.
需要外接一块压力表,沿着挖掘机配件先导手柄液压管到主阀阀盖处,接上压力表就可以了
A pressure gauge needs to be connected externally, along the hydraulic pipe of the pilot handle of the excavator accessories to the main valve cover, and then connect the pressure gauge
三、手柄发抖故障
3、 Handle trembling fault
如果出现挖掘机配件手柄发抖的情况,可以先测量一下先导阀的压力,并且观察液压表的指针是否有来回摆动的情况出现,如果出现该现象,就分解检查先导泵,多数是齿轮磨损严重或掉齿造成先导压力不稳定。
If the handle of excavator accessories trembles, first measure the pressure of the pilot valve and observe whether the pointer of the Hydraulic Gauge swings back and forth. If this phenomenon occurs, disassemble and check the pilot pump. Most of them are caused by serious gear wear or tooth loss, resulting in unstable pilot pressure.
五、先导手柄检测
5、 Pilot handle detection
需要外接一块压力表,沿着挖掘机配件先导手柄液压管到主阀阀盖处,接上压力表就可以了,当然相比先导泵压力,先导手柄的“二次压力”会略低
A pressure gauge needs to be connected externally. Connect the pressure gauge along the hydraulic pipe of the pilot handle of the excavator accessories to the main valve cover. Of course, compared with the pilot pump pressure, the "secondary pressure" of the pilot handle will be slightly lower
