目前,汽车加油站及山区小型油库最常用的是一种自流卸油作业方式。自流卸油能否畅流,一方面取决于油罐车与油罐的高差,另外要看储罐进油管是否能顺利排气,否则将产生气阻,影响卸油速度,甚至卸不下油来。据此在这里介绍两种改进方法。 At present, the most commonly used for gas stations and mountain small oil depots is a self-flow unloading operation. Flow of unloading unobstructed, on the one hand, depends on the tanker and tank height difference, the other depends on whether the storage tank into the exhaust pipe, otherwise it will have air resistance, affecting unloading speed, or even unloaded Come. Here are two improvements introduced here.
