壓力容器,是指盛裝氣體或者液體,承載一定壓力的密閉設備,柴油罐其范圍規定為*工作壓力大于或者等于0.1MPa(表壓),且壓力與容積的乘積大于或者等于2.5MPa?L的氣體、液化氣體和*工作溫度高于或者等于標準沸點的液體的固定式容器和移動式容器;盛裝公稱工作壓力大于或者等于0.2MPa(表壓),且壓力與容積的乘積大于或者等于1.0MPa?L的氣體、液化氣體和標準沸點等于或者低于60℃液體的氣瓶;氧艙等。汽油柴油的膠質增多;潤滑油的酸值增大;潤滑脂的游離堿變小或產生游離酸等。 減少油品輕組分蒸發和延緩氧化變質的主要措施有:降低溫度,減少如果要求不是很嚴格,沒必要清洗。因為柴油和汽油從本質上來說都是石油的輕質裂解產物,化學性質非常接近,只是碳鏈的長短上的差異。如果要求嚴格,就用汽油本身清洗就夠了。柴油是完全溶解于汽油的。(圖/文http://www.yq-mold.com/

Pressure vessel, means for gas or liquid, bearing pressure sealing device, its range is provided for a maximum working pressure greater than or equal to 0.1MPa (g ), and the pressure and the volume of the product is greater than or equal to2.5MPa ?L gas, liquefied petroleum gas and maximum working temperature is higher than or equal to the boiling point of liquid standard fixed container and mobile containers; costumes nominal working pressure greater than or equal to 0.2MPa (g ), and the pressure and the volume of the product is greater than or equal to1.0MPa ?L gas, liquefied gas and standard boiling point is equal to or lower than 60 ℃liquid cylinder chamber. Petrol and diesel oil glial increase; acid number of lubricating oil grease increases; the free alkali or small free acid. Reduce oil light component of evaporation and retard the oxidation of main measures are: to reduce the temperature of reduction, if not very strict requirements, no need of cleaning. Because of diesel and gasoline are essentially oil light pyrolysis products, and chemical properties are very close, but the carbon chain length differences. If the requirement is strict, with gasoline cleaning is enough. Diesel is completely dissolved in oil.
