你知道挖掘机怎么样更换机油吗?

日期:2018-12-07   来源:
弹性臂挖机租赁的发掘机液压油箱所装的液压油是整机液压体系悉数用油的1/2,余下的1/2液压油存储在液压泵、马达、多路阀、液压油缸和各部的管路中.在换油时,如果只更换油箱内的液压油,而不是将整车液压体系中的液压油悉数更换,这种方法只是旧油勾兑新油,如果两种牌号的液压油勾兑在一起,就会引起油液变质。
The hydraulic oil in the hydraulic tank of the excavator leased by the elastic arm excavator is 1/2 of the total oil used in the hydraulic system of the whole machine. The remaining 1/2 hydraulic oil is stored in hydraulic pumps, motors, multiple valves, hydraulic cylinders and pipelines of various parts. When changing oil, if only the hydraulic oil in the tank is replaced, instead of the hydraulic pressure in the hydraulic system of the whole vehicle. Oil replacement, this method is only old oil blending new oil, if the two brands of hydraulic oil blending together, will cause oil deterioration.
1. 一台发掘机更换液压油时 ,应做如下预备:购买整车液压体系用的油。(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。
1. When a excavator replaces the hydraulic oil, the following preparations should be made: purchase the oil for the hydraulic system of the whole vehicle. (Hydraulic tank volume 2.5 times), filter element, washing oil, 3kg flour, rope, oil plug of closed hydraulic tubing, (made according to the tubing of oil-changing excavator), a steam pump and large and small empty oil drum, etc.
预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熄灭。
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 rod and bucket receive the interior point.
2. 液压油箱的清洗:
2. Hydraulic tank cleaning:
将箱内的液压油悉数放出,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。
Release all the hydraulic oil in the tank, remove the hydraulic filter element, remove the pipeline between the pump and the tank from the pump interface, and release the oil in the pipeline. Flush the hydraulic tank and pipeline with washing oil. Clean the inside of the hydraulic tank with medical sandcloth.
将面粉揉和到能拉伸面的程度分成三份,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。液压油箱和滤芯筒内有必要完全清理洁净。更换新的液压滤芯,上好盖板。
The flour is kneaded and stretched into three parts. The dough is used to clean the inside of the hydraulic tank three times, especially the corners of the tank and the filter cartridge. It is necessary to clean the hydraulic tank and filter cartridge completely. Replace the new hydraulic filter element, and fix the cover plate.
3. 液压柱塞泵的冲刷:
3. Flushing of hydraulic plunger pump:
发掘机上每种液压柱塞泵都有冲刷油口,(放油口)。拧开上下放油口,放出泵壳内的液压油,拧上泵下面的油堵,从泵上面的油口向泵壳内注满洗油,再拧开泵下面的油堵,放出泵壳内的洗油,反复冲刷几次后,最后用气泵把泵壳内的余油吹洁净后,注满洁净的液压油,拧紧油堵即可。
Each hydraulic plunger pump on the excavator has a flushing oil outlet (oil outlet). Turn on the top and bottom oil outlets, release the hydraulic oil in the pump shell, screw on the oil plug under the pump, fill the pump shell with washing oil from the top oil outlet of the pump, then screw off the oil plug under the pump, release the oil in the pump shell, wash out repeatedly several times, finally blow the remaining oil in the pump shell with an air pump, fill up the clean hydraulic oil, tighten the oil. Block up.
