ジャックにはどのタイプの油圧オイルが使用されていますか

When we choose hydraulic oil for mechanical floor jack, we mainly consider the following factors:
     1. suitable viscosity, outstanding viscosity-temperature characteristics Viscosity is the first factor to consider when selecting hydraulic oil. Under the same operating pressure, the viscosity is too high, the movement resistance of hydraulic components is added, and the self-priming ability of the hydraulic pump can be decreased by accelerating the temperature, and the pressure drop and power loss of the pipeline increase.If the viscosity is too low, the volume loss of the hydraulic pump will be added, the leakage of the components will increase, and the oil film of the sliding parts will become thin, and the support will be able to decline.
     2. excellent lubrication (wear resistance) The hydraulic system has a lot of moving parts need lubrication to prevent the wear of the relative moving surface, especially the high pressure system, the wear resistance of the hydraulic oil requirements are much higher.
     3. Excellent antioxidant properties The hydraulic oil will also be oxidized in the process of use. After the oxidation of the hydraulic oil, the acid will add corrosion to the metal, and the sludge sediment will block the filter and small gaps, so that the hydraulic system is not normal, so it requires excellent oxidation resistance
     4. Excellent shear stability resistance ポンプを通る油圧オイル、バルブを節約する口とギャップを介して、激しいせん断作用を経験し、粘度剤分子亀裂などのオイルの高分子ポリマーの一部につながるため、粘度が低下します。
5。優れた錆と腐食防止
油圧油を使用する過程で、酸化後に発生する酸性物質だけでなく、水と空気に触れることは避けられません。これは、金属を錆び、腐食させ、油圧システムの通常の動作に影響します。
     6. Excellent anti-emulsification and hydrolysis stability
油圧ポンプやその他の成分の下で水と凝縮液を混合するさまざまな方法からの手術中の油圧油。
     7. Excellent resistance to foam and air release
油圧タンクでは、オイル循環の気泡と混合されたオイルは、システムの圧力を低下させるだけでなく、潤滑条件が悪く、異常なノイズ、振動、空気の領域も触れて油の酸化を加速させるため、油圧油が空気と空気を排出する耐性を必要とします。
     8. the habit of sealing materials
hydraulic mechanical jacks because of the habit of hydraulic oil and sealing material is not good, it will make the sealing material swell, soften or harden to lose the sealing function, so the hydraulic oil and sealing material can be used to each other.
