挖掘机的油缸发生汽蚀及出现白色液体怎么办?

日期:2022-06-29   来源:http://www.dybocheng.com
挖掘机油缸的作用是将发动机输出的机械能转化为液压能,通过主控阀将机械能分配给执行机构,实现挖掘机的每一个动作。那么挖掘机油缸出现气蚀和白液怎么办?
The function of excavator oil cylinder is to convert the mechanical energy output by the engine into hydraulic energy, and distribute the mechanical energy to the actuator through the main control valve to realize each action of the excavator. What about cavitation and white liquid in excavator oil cylinder?
挖掘机油缸发生气蚀?
Cavitation of excavator cylinder?
机械油缸的汽蚀损坏相当大,会导致油缸表面变黑,甚至出现支撑环和密封圈烧焦的现象,从而导致油缸内漏.当气蚀和其他类型的腐蚀一起发生时,气缸主要部件会出现数次甚至数十次加速腐蚀,从而严重影响机械的正常使用。因此,有必要防止气蚀的发生。
The cavitation damage of the mechanical oil cylinder is quite large, which will lead to the blackening of the oil cylinder surface, and even the scorching of the support ring and seal ring, resulting in the internal leakage of the oil cylinder When cavitation erosion and other types of corrosion occur together, the main components of the cylinder will have accelerated corrosion for several times or even dozens of times, which will seriously affect the normal use of the machinery. Therefore, it is necessary to prevent cavitation.
对于汽蚀我们应该采取的预防措施是:严格选用液压油,严格按照液压油的标准选用。选用优质液压油,可有效防止液压系统在工作过程中产生气泡;为了保持各种液压元件接合面的正常间隙,在制造或修理液压缸主要部件时,应按装配尺寸的公差下限装配。
The preventive measures we should take for cavitation are: strictly select hydraulic oil and strictly follow the standard of hydraulic oil. Select high-quality hydraulic oil, which can effectively prevent bubbles in the working process of the hydraulic system; In order to maintain the normal clearance of the joint surfaces of various hydraulic elements, the main components of the hydraulic cylinder shall be assembled according to the tolerance lower limit of the assembly dimension when they are manufactured or repaired.
这样可以很好地减少气蚀的发生;保持油温正常的关键是防止油温过高,减少液压冲击,合理设计散热系统,防止油温过高。如有异常,应及时查找原因并排除。
This can well reduce the occurrence of cavitation; The key to keep the oil temperature normal is to prevent the oil temperature from being too high, reduce the hydraulic impact, and reasonably design the heat dissipation system to prevent the oil temperature from being too high. In case of any abnormality, the cause shall be found and eliminated in time.
同时,应及时维护冷却系统,使冷却系统的温度保持在适当的范围内,以减少气泡破裂时释放的能量。必要时可将油缸拆成油管,使液压油溢出,达到单缸排气的效果。
At the same time, the cooling system shall be maintained in time to keep the temperature of the cooling system within an appropriate range, so as to reduce the energy released in case of bubble rupture. If necessary, the oil cylinder can be disassembled into oil pipe to overflow the hydraulic oil and achieve the effect of single cylinder exhaust.

挖掘机油缸里的白色液体?
White liquid in excavator cylinder?
挖掘机在长期使用、频繁使用的零部件时,出现的磨损、故障现象,驾驶挖掘机的朋友们一定要对这些现象有充分的认识,并有针对性的解决。然而,对于机械使用中未知杂质的问题知之甚少。例如,挖掘缸内有白色液体。这是什么白色液体
When the excavator is used for a long time and frequently, there are wear and failure phenomena. The friends driving the excavator must have a full understanding of these phenomena and solve them pertinently. However, little is known about the problem of unknown impurities in the use of machinery. For example, there is white liquid in the digging cylinder. What is this white liquid
事实上,加长臂挖掘机租赁厂家提醒,液压油在水中会变成乳白色。如果水箱也出现这种情况,则需要清洗液压系统,更换液压油。挖掘机更换液压油时,需要将油箱内的液压油全部放掉,取出液压滤芯,从泵接头上断开泵与油箱之间的管路,将油箱内的油放掉。用医用布擦拭液压缸内部。
In fact, the leasing manufacturer of the lengthening arm excavator warned that the hydraulic oil would turn milky white in water. If this happens to the water tank, it is necessary to clean the hydraulic system and replace the hydraulic oil. When the excavator changes the hydraulic oil, it is necessary to drain all the hydraulic oil in the oil tank, take out the hydraulic filter element, disconnect the pipeline between the pump and the oil tank from the pump connector, and drain the oil in the oil tank. Wipe the inside of the hydraulic cylinder with a medical cloth.
挖掘机液压柱塞泵冲洗油口,开口排油,液压油的泵壳松开下方螺杆泵的油塞,从泵到泵油口外壳充满油,然后打开泵油塞底面放出洗油清洗泵壳后,清洗数次,将泵壳内的残油吹净,注入干净的液压油,将油塞紧。
Flush the oil port of the hydraulic piston pump of the excavator, drain the oil at the opening, loosen the oil plug of the screw pump below the pump housing of the hydraulic oil, fill the oil from the pump to the pump housing, then open the bottom surface of the pump plug to drain the washing oil, clean the pump housing for several times, blow out the residual oil in the pump housing, inject clean hydraulic oil, and plug the oil tightly.
