加长臂挖掘机液压缸为什么会出现气蚀?

日期:2022-04-25   来源:http://www.dybocheng.com
  加长臂挖掘机的正常使用甚至是更好的使用都离不开零部件的完好无损坏,其中液压缸的质量好坏对工程机械的使用效能有着重要的影响,但也会出现一些问题需要及时进行处理,如果这个问题--加长臂挖掘机液压缸为什么会出现气蚀?
  The normal use of extended arm excavator even better use cannot leave the parts in good condition no damage, engineering machinery hydraulic cylinder's quality in case of the use of performance has an important influence, but also can appear some problems to be handled in time, if this problem - extended arm excavator hydraulic cylinder why cavitation?
  加长臂挖掘机出现气蚀,主要是由于液压缸在工作过程中在活塞和导向套之间的油液中混入了一定量的空气。随着压力的逐渐升高,油液当中的气体会变成气泡,当压力升高到某一极限值时,这些气泡在高压的作用下就会发生破裂,从而将高温、高压的气体迅速作用到零件的表面上,导致加长臂挖掘机液压缸产生气蚀,造成零件的腐蚀性损坏。
  The cavitation of the extended arm excavator is mainly due to the fact that a certain amount of air is mixed into the oil between the piston and the guide sleeve in the working process of the hydraulic cylinder. With the rising of pressure, gas will become the bubble of the oil, when the pressure increases to a certain limit, the bubbles burst will occur under the action of high pressure, thus rapid action to the high temperature and high pressure gas on the surface of the parts, lead to lengthen arm excavator hydraulic cylinder to produce cavitation, parts of corrosive damage.
  当液压缸零件表面与液压油的相对速度增加时,溶解在液压油中的气体很容易析出并产生气泡。气泡流到高压区后会破裂,瞬间产生的高压显微镜水射流和冲击力会继续作用在液压缸零件表面,从而在液压缸零件表面产生气蚀,液压缸气蚀引起的标准与液压泵站架构、液压缸零部件原材料、液压油质量、制造和维护有关。
  When the relative velocity of hydraulic cylinder parts surface and hydraulic oil increases, the gas dissolved in the hydraulic oil is easy to precipitate and produce bubbles. The bubble will break when it flows to the high pressure area, and the instantaneous high pressure microscope water jet and impact force will continue to act on the surface of the hydraulic cylinder parts, so as to produce cavitation on the surface of the hydraulic cylinder parts. The standard caused by cavitation of the hydraulic cylinder is related to the structure of the hydraulic pump station, the raw materials of the hydraulic cylinder parts, the quality of hydraulic oil, manufacturing and maintenance.
  那么有什么方法可以预防呢?维修时注意排气液压缸,保养后,液压系统应平稳运行一定时间,使液压系统中的液压油能充分循环;油液溢出,达到单个液压缸排气的效果。此外要严格按照油品标准选用液压油,选用优质的液压油,可以有效防止液压系统在工作过程中产生气泡。选油时,应根据不同地区的低温度进行选择,并按油尺标准加注液压油。同时,应保持液压系统清洁,经常检查液压油的油质。
  So what can be done to prevent it? Pay attention to the exhaust hydraulic cylinder during maintenance. After maintenance, the hydraulic system should run smoothly for a certain time, so that the hydraulic oil in the hydraulic system can be fully circulated; Oil overflow to achieve the effect of single hydraulic cylinder exhaust. In addition, hydraulic oil should be selected strictly in accordance with oil standards, and high-quality hydraulic oil can effectively prevent bubbles in the working process of the hydraulic system. When selecting oil, it should be selected according to the low temperature in different areas, and fill hydraulic oil according to the oil ruler standard. At the same time, the hydraulic system should be kept clean, often check the oil quality of hydraulic oil.
