东莞石碣-望牛墩46壳牌液压油-真空泵油经销

　　(l)合适的粘度和良好的粘温性能，以保证液压元件在工作压力和工作温度发生变化的条件下得到良好润滑、冷却和密封。

　　(2)良好的极压抗磨性，以保证油泵、液压马达、控制阀和油缸中的摩擦副在高压、高速苛刻条件下得到正常的润滑，减少磨损。

　　(3)优良的抗氧化安定性、水解安定性和热稳定性，以抵抗空气、水分和高温、高压等因素的影响或作用，使其不易老化变质，延长使用寿命。

　　(4)良好的抗泡性和空气释放值，以保证在运转中受到机械剧烈搅拌的条件下产生的泡沫能迅速消失;并能将混入油中的空气在较短时间内释放出来，以实现准确、灵敏、平稳地传递静压。

　　(5)良好的抗乳化性，能与混入油中的水分迅速分离，以免形成乳化液，引起液压系统的金属材质锈蚀和降低使用性能。

　　(6)良好的防锈性，以防止金属表面锈蚀。(L) proper viscosity and good viscosity-temperature performance to ensure that the hydraulic components in the operating pressure and temperature changes under the conditions of good lubrication, cooling and sealing. (2) good extreme pressure and anti-wear performance to ensure that the friction pairs in the oil pump, hydraulic motor, control valve and oil cylinder get normal lubrication under high pressure and high speed and harsh conditions to reduce wear. (3) excellent anti-oxidation stability, hydrolytic stability and thermal stability to resist the influence or action of air, moisture, high temperature, high pressure, etc. . (4) good anti-foaming property and air release value to ensure that the foam produced under the condition of severe mechanical agitation in operation can disappear quickly, and can release the air mixed in the oil in a relatively
