润滑油静电放电的危害有哪些?

发布时间2019-06-27  来源:http://www.wunqdctk.com

  如果润滑油中积聚了大量电荷,就会发生静电放电。在某些情况下,它甚至可能引起静电火花,造成安全隐患,甚至燃烧和爆炸。通常情况下,静电放电发生在滤芯或油箱中,产生轻微的裂纹。如果静电电压高,静电可能会连续发生好几次。静电放电更可能发生在不同材料大面积接触的地方。由于润滑油的滤芯使用较多的塑料,与润滑油接触时容易产生静电。
  If a large amount of charge is accumulated in lubricating oil, electrostatic discharge will occur. In some cases, it may even cause electrostatic sparks, causing potential safety hazards, even combustion and explosion. Usually, electrostatic discharge (ESD) occurs in the filter element or fuel tank, causing slight cracks. If the static voltage is high, static electricity may occur several times in a row. Electrostatic discharge (ESD) is more likely to occur in large areas of contact between different materials. Because the filter element of lubricating oil uses more plastics, it is easy to generate static electricity when contacting with lubricating oil.
  静电放电时电火花引起的瞬时高温可接近1000℃,如果石油本身是易燃的,这是危险的。此外,如果原油中碳氢化合物混合物的蒸汽在储罐附近达到一定浓度,也有自燃的危险。汽轮机油和液压油在循环流动时也会产生静电和放电,但它们通常很快就会熄灭。
  In electrostatic discharge, the instantaneous high temperature caused by electric spark can be close to 1000 C, which is dangerous if the oil itself is flammable. In addition, if the vapor of hydrocarbon mixture in crude oil reaches a certain concentration near the tank, there is also a risk of spontaneous combustion. Turbine oil and hydraulic oil also generate static electricity and discharge when circulating, but they usually go out soon.
  如何防止润滑油中的静电问题:如果润滑系统容易产生静电问题,接地是一种常用的消除静电的方法,但在某些情况下接地可能不是解决问题的办法。如果接地不能解决静电问题,下面是另外四种消除静电的方法:

  How to prevent electrostatic problems in lubricating oil: If the lubricating system is prone to electrostatic problems, grounding is a commonly used method to eliminate electrostatic problems, but in some cases grounding may not be the solution. If grounding can't solve the problem of static electricity, here are four other ways to eliminate static electricity:
  1. 采用防静电滤芯,材料制成,能及时导走静电,防止静电放电。2. 在施油的前提下,改用导电性较高的润滑油。然而,应该充分评估和避免石油替代的风险。
  1. Anti-static filter element, made of material, can guide static electricity in time and prevent static discharge. 2. On the premise of oil application, the lubricant with higher conductivity should be used. However, the risk of oil substitution should be fully assessed and avoided.
  3.对润滑系统的零部件材料和组合方式进行改造,使用不易产生静电的材料,或避免静电积聚。4. 调节流量和油箱大小,减少油在循环流动中的摩擦。以上是对润滑油静电放电的介绍及预防措施,希望对您有所帮助!
  3. Revamping the materials and combinations of parts and components of lubrication system, using materials that are not easy to generate static electricity, or avoiding the accumulation of static electricity. 4. Adjust flow rate and tank size to reduce friction of oil in circulating flow. Above is the introduction and preventive measures of electrostatic discharge of lubricating oil, hope to help you!
