Resistance to foaming of the hydraulic oil is better

1) shall not contain steam, air and other easy to gasification and gas impurities,or from the bubble, so that the work to occur flutter npt pipe fittings move, affecting the smooth working. Mass fraction o f water Germany shall not exceed 0.025%, the formation of water vapor, water will deteriorate the performance of the use of oil and impact of low-temperature work. Resistance to foaming of the hydraulic oil is better, the defoaming stronger. tube fitting Mineral oil usually can be dissolved in the atmosphere of 5% to 10% air, which is the main bubble to reason. Hydraulic pump oil absorption tube seal is not good to improper teflon hose hydraulic fittings installation or management, will produce the foam, it makes the hydraulic pump to generate noise and vibration dynamic characteristics of deterioration and therefore requires the hydraulic oil can be quickly and fully to defoaming, otherwise it will create the power loss increases, the temperature rise, The action is not stable.
2) erosion of parts and damage seals, that does not contain water-soluble acid and alkali ingredients.
3) in the working temperature and pressure, with excellent lubrication, shear stability and film strength.
4) chemical stability. Should not be in the process of storage and work production of oxide colloid, long-term use is not degenerate. When the system temperature degrees, pressure and flow rate changes, still maintain its original character, in the course of deterioration, no precipitation of asphalt, tar and other glial precipitation.
5) to minimize the impurities in the oil, does not allow precipitation to avoid wear and tear parts, clogging pipes and hydraulic components, affecting the system job.
