挖掘机的油缸发生汽蚀怎么办?

日期:2022-08-19   来源:http://www.dybocheng.com
液压挖掘机的作用是将发动机输出的机械能转换成液压能,通过先导阀将机械能分配给执行机构,实现挖掘机的所有动作。挖掘机的油缸里出现气蚀和白液怎么办?长臂挖掘机租赁厂家来告诉您!
The function of the hydraulic excavator is to convert the mechanical energy output by the engine into hydraulic energy, distribute the mechanical energy to the actuator through the pilot valve, and realize all actions of the excavator. What about cavitation and white liquid in the oil cylinder of the excavator? Long arm excavator rental manufacturers to tell you!
长臂挖掘机电机腐蚀严重,油缸表面变黑,支撑环和密封圈出现烧焦现象,导致油缸内泄漏。气蚀与其他类型的腐蚀一起发生时,缸体关键部件会发生几次甚至几十次加速腐蚀,严重影响机器的正常使用。因此,有必要防止气蚀的发生。
The motor of the long boom excavator is severely corroded, the surface of the oil cylinder is blackened, and the support ring and seal ring are burnt, resulting in leakage in the oil cylinder. When cavitation corrosion occurs together with other types of corrosion, the key parts of the cylinder block will undergo several or even dozens of accelerated corrosion, which seriously affects the normal use of the machine. Therefore, it is necessary to prevent cavitation.
我们对汽蚀应采取的预防措施是严格选择液压油,严格按照液压油标准选择。选用液压油,有效防止液压系统在工作中产生气泡;为了保持各种液压元件接合面的正常间隙,制造或修理液压缸的主要零件时,应按组装尺寸的公差下限进行组装。
The preventive measures we should take against cavitation are to strictly select hydraulic oil and strictly follow the hydraulic oil standard. Hydraulic oil is selected to effectively prevent air bubbles in the hydraulic system during operation; In order to maintain the normal clearance of the joint surfaces of various hydraulic elements, the main parts of the hydraulic cylinder shall be assembled according to the lower tolerance limit of the assembly dimension when manufacturing or repairing.

由此,能够有效地减少气蚀产生;保持油温正常的关键是避免油温过高,减少液压冲击,合理设计散热系统,避免油温过高。如有异常,应立即查找原因并排除。
Thus, cavitation generation can be effectively reduced; 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 cooling system to avoid the oil temperature from being too high. In case of any abnormality, immediately find out the cause and eliminate it.
同时,要及时维护长臂挖掘机的冷却系统,使冷却系统的温度保持在合适的范围内,以减少气泡破裂时释放的能量。根据需要将气缸成气管,使液压油溢出,可以获得单缸的排气效果。
At the same time, the cooling system of the long arm excavator shall be maintained in time to keep the temperature of the cooling system within an appropriate range to reduce the energy released when the bubble breaks. According to the needs, the air cylinder is piped to overflow the hydraulic oil, and the exhaust effect of a single cylinder can be obtained.
总之,日常维修保养要注意,挖掘机液压油缸在维修后,应使液压系统平稳地运转一定的时间,以使液压系统中的液压油得到充分循环。在修理液压缸的主要零件时,应按照装配尺寸的公差下限值进行装配,这样可以很好地减少气蚀现象的发生。更多问题的了解就来我们网站http://www.dybocheng.com咨询看看吧。
In short, attention should be paid to the daily maintenance. After the hydraulic cylinder of the excavator is repaired, the hydraulic system should run smoothly for a certain time, so that the hydraulic oil in the hydraulic system can be fully circulated. When repairing the main parts of the hydraulic cylinder, the assembly shall be carried out according to the tolerance lower limit of the assembly dimension, so as to reduce the occurrence of cavitation.
