你知道我们日常该怎么样给挖掘机更换液压油吗?

日期:2018-12-04   来源:上海体彩网http://www.rbaras.com
发掘机出租日常维护过程中偶然会遇到要替换液压油的问题,替换液压油并不简略,需要把握一定的方法。下面就简略介绍下替换液压油的准备作业。
During the daily protection process of excavator rental, there are occasional problems of replacing hydraulic oil。 It is not easy to replace hydraulic oil, so we need to master certain methods。 Here is a brief introduction to the preparation of replacement of hydraulic oil。
1、购买整车液压系统用的油。(液压油箱容积的2。5倍),滤芯,洗油,3公斤面粉,绳子,封闭液压油管的油堵,(按换油的发掘机上的油管制造)一台汽泵和巨细空油桶等。准备一台正常的发掘机。将换油的发掘机动臂抬升到最高点,斗杆及铲斗收到内点后发动机平息(动臂缸,斗杆缸和铲斗缸的缸杆全部伸出到顶点)。
1. Purchase oil for hydraulic system of vehicle. (Hydraulic tank volume 2. Five times), filter element, washing oil, 3kg flour, rope, oil plug of closed hydraulic tubing (made according to the tubing of the oil-changing excavator), a steam pump and a large and thin empty oil barrel, etc. Prepare a normal excavator. Lift the arm of the oil-changing excavator to the highest point, and the engine will be extinguished when the bucket bar and bucket receive the interior point (all the cylinder bars of the boom cylinder, bucket cylinder and bucket cylinder reach the apex).
2、液压油箱的清洗:将箱内的液压油全部放出,撤出液压滤芯,把泵和油箱之间的管路从泵的接口处拆开,放出管路内的油液。用洗油冲刷液压油箱和管路。用医用沙布把液压油箱内部擦净。将面粉揉和到能拉伸面的程度分红三份,用面团分三次粘洁净液压油箱的里面尤其是油箱的边角处和滤芯筒。
2. Hydraulic tank cleaning: all the hydraulic oil in the tank is discharged, the hydraulic filter element is withdrawn, and the pipeline between the pump and the tank is dismantled from the interface of the pump, and the oil in the pipeline is discharged. Flush the hydraulic tank and pipeline with washing oil. Clean the inside of the hydraulic tank with medical sandcloth. Knead the flour and divide the flour into three parts to the extent that it can stretch the surface. Use the dough to stick the inside of the hydraulic tank three times, especially the corner of the tank and the filter cartridge.

日常作业过程中偶然会遇到发掘机加长臂小臂动作慢的情况发生,呈现此种情况的原因是什么呢,能够从一下几个方面来考虑。
In the course of daily operation, occasionally encounter the slow movement of the elongated arm of excavator。 What is the reason for this situation? We can consider it from the following aspects。
1、大臂与小臂无法抬起跟外伸,此缺点基本上是大臂跟小臂的曲轴传感器损坏,此传感器功用相当于一个一般电位器,用于感知作业臂的角度,避免过度操作发生倾翻或磕碰
1。 The upper arm and the lower arm can't lift and extend the heel。 The problem is basically that the crankshaft sensor of the upper arm and the lower arm is damaged。 The function of the sensor is equivalent to a common potentiometer, which is used to sense the viewpoint of the working arm to avoid overoperation, overturning or knocking。
2、假如传感器呈现缺点或线路搭铁短路有问题,就会引起上述缺点的呈现,这个传感器不易购买,解决方法是用两只电阻来替代传感器相同能够使发掘机能正常作业,不过会失掉维护功用。
2. If the sensor is faulty or the line is short-circuited, it will cause the above-mentioned faults. This sensor is not easy to buy. The solution is to replace the sensor with two resistors, which can also make the excavator work normally, but will lose its protective function.
