挖掘机长臂表面看上去虽然很硬朗，但是实际上，如果在维修保养方面方法不恰当就很容易出现问题。当前，很多人都在维修的过程当中存在了很多错误的做法，从而影响其日常工作性能，甚影响挖掘机的寿命。
Although the surface of the long arm of the excavator looks very hard, in fact, if the maintenance method is not appropriate, it is easy to have problems. At present, many people have many wrong practices in the process of maintenance, which affect their daily work performance and even the service life of excavators.
挖掘机加长臂的类型很多种，通常可以分为两段式加长臂和三段式加长臂，还有四段式加长臂，这种型号的臂相对少点。跟大家分享下华体会国际 的分类和作用。
There are many types of excavator lengthening arm, which can be divided into two-stage lengthening arm, three-stage lengthening arm and four-stage lengthening arm. This type of arm is relatively few. Share with you the classification and function of the lower lengthening arm excavator.
华体会国际 熄火是什么原因呢
What is the reason for the flameout of the extended arm excavator
1、华体会国际 的柴油机空气，就会柴油机压力不足，出现熄火的现象；低压油路存在漏气现象，也会华体会国际 熄火现象的发生。可以打开华体会国际 柴油机上的放气螺钉，后不断地泵油，将柴油机中的空气排除干净；检查华体会国际 低压油路的漏气点，采取密封处理即可。
1. If the air of the diesel engine of the lengthening arm excavator is insufficient, the diesel engine will stall; There is air leakage in the low-pressure oil circuit, which will also lead to the flameout of the extended arm excavator. You can open the bleed screw on the diesel engine of the lengthening arm excavator, and then pump oil continuously to eliminate the air in the diesel engine; Check the air leakage point of the low-pressure oil circuit of the lengthening arm excavator and take sealing treatment.
2、检查输油泵的工作情况，应在柴油管路通畅无阻、密封而无空气情况下进行。检查时拧松喷油泵上的放气螺钉，并在按下柴油机启动按钮的同时，察看放气螺钉处的流油情况。
2. Check the working condition of the oil transfer pump when the diesel pipeline is unobstructed and sealed without air. During inspection, loosen the bleed screw on the fuel injection pump, and observe the oil flow at the bleed screw while pressing the diesel engine start button.
3、华体会国际 柴油机喷油泵工作时，低压油路的油压低于大气压，因而低压油路进气引起华体会国际 供油故障的现象比较常见，方法是查出低压油路进气的地方，采取密封措施。
3. When the fuel injection pump of the diesel engine of the lengthening arm excavator works, the oil pressure of the low-pressure oil circuit is lower than the atmospheric pressure, so the phenomenon of oil supply failure of the lengthening arm excavator caused by the air inlet of the low-pressure oil circuit is common. The solution is to find out the air inlet of the low-pressure oil circuit and take sealing measures.
华体会国际 租赁在使用挖掘机加长臂作业的过程中经常会遇到一些特殊的工作环境，比如挖管道，石块装车等。如果想要使加长臂在任何工作环境下都能有较高的效率，那么操作手一定要一定的操作技巧。
In the process of using the excavator to lengthen the arm, we often encounter some special working environments, such as digging pipelines, loading stones and so on. If you want to make the lengthening arm more efficient in any working environment, the operator must have certain operating skills.
The above is the knowledge brought to you today. The leasing of lengthening arm excavator has focused on the industry for many years and continuously provided users with valuable content. Please continue to pay attention to us for more content: //www.wondgo.com
