Compared with the fuel injector for the mechanical fuel system, the fuel injector for the electric control fuel system has more spray holes and smaller spray hole diameter. Meanwhile, the oil injection pressure of the electronic control fuel injection system is higher, so that the requirement on the matching precision of the coupling piece of the oil injector is higher, the requirement on the water content of diesel is higher, and the fuel with high water content can cause the rusting and blocking of the coupling piece of the oil injector and the spray hole of the oil injector after passing through the fuel system of the explosion-proof electronic injection diesel engine until the oil injector is blocked, thereby influencing the fuel injection and causing the power abnormality of the diesel engine and even flameout and other fault phenomena. At present, most explosion-proof electronic injection diesel engines are not provided with oil-water separators. The oil-water separator is one kind of fuel oil filter and its principle is to utilize gravity settling principle to eliminate impurity and water based on the density difference between water and fuel oil. When the water in the oil-water separator reaches a certain amount, the water needs to be discharged, and usually, the oil-water separator uses a manual water discharge valve, so that a driver is required to regularly discharge the water, and the degree of automation is low.
