挖掘机液压油的互换要领!

  一台掘客机液压油箱所装的液压油是零件液压体系全部用油的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,倘若只互换油箱内的液压油,而不是将整车液压体系中的液压油全部互换,这种步伐只是旧油‘沟兑新油,.倘若两种牌号的液压油沟兑在一同,还会惹起油液蜕变。
  The hydraulic oil in the hydraulic tank of a excavator is 1/2 of the total oil used in the hydraulic system of the whole machine. The remaining 1/2 of the hydraulic oil is stored in the hydraulic pumps, motors, multi-way valves, hydraulic cylinders and pipelines of all parts. When changing the oil, if only the hydraulic oil in the tank is changed, instead of the hydraulic oil in the hydraulic system of the whole vehicle, this method can only be used. It's the old oil'ditch to new oil'. If the two brands of hydraulic ditches are mixed together, it will cause the oil to degenerate.
  比如一台住友HS220型/掘客机,全车液压体系所用的液压油为420L,而液压油箱的液压油是225L,余下的油液都存储在体系中。种种品牌的掘客机全车液压体系用油与油箱的容积比例其本上是差异的。1互换液压油时预备变乱
  For example, a Sumitomo HS220/excavator uses 420 L hydraulic oil for the whole vehicle hydraulic system and 225L hydraulic oil for the hydraulic tank. The remaining oil is stored in the system. Various brands of excavators have different volumetric ratios of oil and tank for the whole vehicle hydraulic system. 1 Preparations for changing hydraulic oil
  ﹙1﹚一台掘客机互换液压油时,应做如下预备:购置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,绳索,封锁液压油管的油堵,(按换油的掘客机上的油管配制)一台汽泵和大小空油桶等。预备一台正常的掘客机。将换油的掘客机动臂抬升到最高点,斗杆及铲斗收到内点后倡议机熄灭.(动臂缸,斗杆缸和铲斗缸的缸杆全部伸出到顶点)。
  (1) When a excavator changes the hydraulic oil, it should make the following preparations: purchase the oil for the hydraulic system of the whole vehicle. (Hydraulic tank volume 2. Five times), filter element, washing oil, 3kg flour, rope, oil plug for blocking hydraulic tubing, a steam pump and empty oil barrel of different sizes, etc. Prepare a normal excavator. Lift the boom of the oil-changing excavator to the highest point, and the bucket bar and bucket will be extinguished after receiving the interior point. (The cylinder bars of the boom cylinder, bucket cylinder and bucket cylinder all extend to the apex.)

  ﹙2﹚液压油箱的洗濯:将箱内的液压油全部放出,撤出液厢式压滤机芯,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。用洗油冲洗液压油箱和管路。用医用沙布把液压油箱外部擦净。将面粉揉和到能拉伸面的水中分红三份,用面团分三次粘洁净液压油箱的内里格外是油箱的边角处和滤芯筒。液压油箱和滤芯筒内必需彻底整理洁净。互换新的液压滤芯,上好盖板。
  (2) Hydraulic tank cleaning: all the hydraulic oil in the tank is discharged, the filter press core is withdrawn, the pipeline between the pump and the tank is dismantled from the interface of the pump, and the oil in the pipeline is released. Flush the hydraulic tank and pipeline with washing oil. Clean the inside of the hydraulic tank with medical sandcloth. The flour is kneaded and divided into three parts at the level of the stretchable surface. The dough is divided into three parts to stick the inside of the hydraulic tank, especially the corner of the tank and the filter cartridge. The hydraulic tank and filter cartridge must be cleaned thoroughly. Replace the new hydraulic filter element and put on the cover.
  ﹙3﹚液压柱塞泵的冲洗:掘客机上每种液压柱塞泵都有冲洗油口,(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,从泵下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,重复冲洗重复后,着末用汽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,Badge。
  (3) Flushing of hydraulic plunger pump: Each hydraulic plunger pump on excavator has 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 it several times, and finally blow the remaining oil in the pump shell clean with the steam pump, fill up the clean hydraulic oil, tighten the oil. Just plug up, Badge.
  ﹙4﹚互换泵进油口密封圈,(O形圈),将液压油箱衔接到泵的供油管路衔接好,从液板框压滤机芯油口(放好互换后的滤芯)向液压油箱内注满洁净的液压油。
  (4) Change the seal ring of the oil inlet of the pump, (O-ring), connect the hydraulic tank to the oil supply pipeline of the pump, and fill the hydraulic tank with clean hydraulic oil from the oil outlet of the core of the hydraulic plate-frame filter press (after replacing the filter core).
