There are three kinds of oil on an oil tank. How should they be unloaded?
There are three different kinds of oil in a car, so this tanker must be divided into compartments. It depends on whether one of the three cabins will share one discharge pipeline or three separate oil unloading pipelines.
Sharing one, it is necessary to adjust the closed valve according to the characteristics of the piping layout, each compartment must be reserved with a sub valve, close the other two compartment valve, open the unloading tank of the sub valve, and then open the pipe valve.
Three cabins have independent unloading pipeline, then there is no need to say more, switch directly to cover cabin, independent pipeline can.
