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.
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. Hydraulic tank cleaning:
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.
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. Flushing of hydraulic plunger pump:
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.
