溫度如何影響油品品質？
Your pump oil’s durability depends on many parameters and temperature has a big influence. Too hot or too cold, both can cause issues. An overview: Mineral oils: their max temperature limit would be 80°C (176°F), above that the oil will thicken. We find that every 10°C temperature increase reduced the oil service life by half. Synthetic oils endure a permanent operation at 100-160°C (212-320°F). PFPE oils are almost inert, they’re not as subject to typical oil ageing. Therefore, PFPE oils can stand permanent temperatures of up to 250°C (482°F). Operating conditions can also be too cold for the oil and as a result, water (and other) vapors may condense. Condensed liquid can cause loss of lubrication properties and even corrosion in the pump.
您幫浦油品的耐用性取決於多項參數，溫度就是其中一項。礦物油最高溫度限制為 80°C (176°F)，若高於此值，油品會變濃。我們發現每增加 10°C 溫度，就會讓油品使用壽命縮短一半。合成油能在 100-160°C (212-320°F) 下長期使用。PFPE 油品接近惰性，不會像一般油品會發生老化。因此，PFPE 油品能常態性承受最高達 250°C (482°F) 的溫度。部分運作環境條件也可能對機油來說過冷，導致水 (及其他) 蒸汽產生凝結。冷凝液體可能會使潤滑性質消失，甚至致使幫浦發生腐蝕。
