Novel locomotive fuel oil stratified recovery device and use method thereof

Abstract

The invention discloses a novel locomotive fuel oil stratified recovery device and a use method thereof, and relates to the technical field of mechanical engineering. The novel locomotive fuel oil stratified recovery device comprises a container, wherein fuel oil and water are arranged in the container, an oil inlet is formed in the left side of the top of the container, an oil outlet and an inspection drainage port are sequentially formed in the right side of the container from top to bottom, and the oil outlet is formed in the position 2 / 3 away from the bottom face in the elevation direction. The novel locomotive fuel oil stratified recovery device and the use method thereof have the advantages that by designing the novel locomotive fuel oil stratified recovery device, oil-water stratification can be carried out on return oil of a diesel injector, clean fuel oil is recovered into a fuel tank, it is avoided that water is mixed into the fuel oil, the water leakage fault of a sheath of the diesel injector can be found in time, and larger faults are avoided.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a novel locomotive fuel layer recovery device and a method for using the same. Background technique [0002] When the fuel injector of a diesel engine sprays the atomized fuel into the cylinder, a part of the fuel will go through the gap between the matching surfaces of the injector coupler, go through the oil return pipe, and return directly to the fuel tank. [0003] The fuel injector is installed in the fuel injector jacket in the cylinder liner, and the oil return pipe communicates with the jacket cavity. If the fuel injector jacket cracks and leaks, the water will directly enter the fuel tank from the oil return main pipe. If the fuel contains water, it will corrode the oil circuit and rust the fuel system components, affect the normal fuel supply of the fuel system, and seriously cause the sudden stop of the locomotive. This kind of failure is very concealed...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a novel locomotive fuel layer recovery device and its use method, which solves the problem that the fuel injector is installed in the injector sheath in the cylinder liner, and the oil return pipe and the sheath cavity If there is a crack and water leakage in the injector jacket, the water will directly enter the fuel tank from the fuel return pipe, resulting in water in the fuel, which will corrode the oil circuit and rust the fuel system components, affecting the normal fuel supply of the fuel system, seriously Faults that can cause a sudden stop of the locomotive
