气液增压泵液压系统运作时出现的空穴如何处理?

  现象:如果气液增压泵液压系统(由液体增压泵和箱体组成)渗入空气,和气泡在液体中移动到区域与高压液体流动,气泡在高压的作用下,很快就会破裂造成当地的液压冲击,导致噪音和振动。此外,由于气泡破坏了流体流动的连续性,降低了管道的油流量,造成流量和压力的波动,使液压元件承受冲击载荷,影响其使用寿命。
  Phenomenon: if the hydraulic system of the gas-liquid booster pump (composed of the liquid booster pump and the box) penetrates into the air, and the bubble moves to the area in the liquid and flows with the high-pressure liquid, the bubble will break under the effect of high pressure and cause the local hydraulic impact, resulting in noise and vibration. In addition, because the bubble destroys the continuity of fluid flow, reduces the oil flow of the pipeline, causes the fluctuation of flow and pressure, makes the hydraulic components bear the impact load, and affects their service life.
  原因:液压油总是含有一定量的水,这些水通常溶解在油中或以气泡的形式混合在一起。当压力低于空分压力时,油中溶解的空气分离形成气泡。当压力降油的饱和蒸汽压以下时,油就会沸腾并产生气泡。这些气泡与油混合形成不连续状态,这种现象称为空化。

  Cause: hydraulic oil always contains a certain amount of water, which is usually dissolved in oil or mixed in the form of bubbles. When the pressure is lower than the air separation pressure, the dissolved air in the oil separates and forms bubbles. When the pressure drops below the saturated vapor pressure of the oil, the oil boils and creates bubbles. These bubbles mix with oil to form a discontinuous state, which is called cavitation.
  位置:吸油口及吸油管低于常压,容易产生气蚀;当油通过节流孔等狭窄间隙流动时,由于速度的增加,压力下降,也会产生气蚀现象。
  Location: if the suction port and suction pipe are lower than normal pressure, cavitation is easy to occur; when the oil flows through the narrow gap such as throttle hole, cavitation will also occur due to the increase of speed and the decrease of pressure.
  伤害:泡沫油高压区域和移动迅速打破在高压的作用下,导致周围突然减少体积和高速流高压油来补充,导致局部瞬时的影响,压力和温度急剧上升,强烈的噪音和振动。
  Damage: high pressure area and movement of foam oil rapidly break down under high pressure, resulting in sudden reduction of volume around and high speed flow of high pressure oil to replenish, resulting in local instantaneous effects, pressure and temperature rise sharply, strong noise and vibration.
  措施:正确设计液压泵的结构参数和泵的吸入管路,尽量避免油路内狭窄和急弯,防止产生低压区;合理选择机械材料,提高机械强度,改善表面质量,提高耐腐蚀能力。
  Measures: correctly design the structural parameters of the hydraulic pump and the suction pipeline of the pump, try to avoid the narrow and sharp bend in the oil circuit, prevent the low-pressure area; reasonably select the mechanical materials, improve the mechanical strength, improve the surface quality, and improve the corrosion resistance.
