Embodiment Construction

[0014] The technical solutions of the present invention will be clearly and completely described below through specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0015] Such as figure 1 As shown, the exhaust pump used in the fuel system, the exhaust pump is installed between the coarse filter and the fine filter of the fuel system of the whole vehicle, and the fuel is passed from the fuel tank to the diesel coarse filter and then reaches the diesel fine filter through the exhaust pump, and is supplied to the diesel engine. After the internal circulation of the diesel engine, the remaining fuel flows back to the fuel tank; the exhaust pump mainly consists of a handle mechanism (1) and ...

Abstract

The invention relates to the technical field of engine fuel oil systems, in particular to an exhaust pump for a fuel oil system. The exhaust pump is installed between a fuel oil system coarse filter and a fuel oil system fine filter, the exhaust pump is mainly composed of a handle mechanism and a pump body mechanism, and the handle mechanism is installed above the pump body mechanism. The exhaust pump solves the problems that air in the fuel oil system cannot be normally exhausted, a fuel oil pipeline cannot be filled with fuel oil, the fuel oil cannot be smoothly conveyed to a fuel injection pump, and an engine is not easy to start; and meanwhile the exhaust pump has the advantages of being high in temperature resistance, easy, convenient and rapid to operate, high in reliability and the like.

Description

technical field [0001] The invention relates to the technical field of engine fuel system, in particular to an exhaust pump used in the fuel system. Background technique [0002] When the diesel engine is started for the first time or stored for a long time, there is air in the fuel system pipeline, and the fuel cannot be continuously delivered to the fuel injection pump, which makes the engine difficult to start; in order to ensure that the air in the system is removed, the system is filled with fuel, so that the diesel engine is easy to start the goal of. During maintenance of the fuel system, use this pump to discharge the air in the system, so that the fuel in the fuel tank can be delivered to the fuel system, so as to ensure the normal start of the engine. Contents of the invention [0003] In view of the above-mentioned defects, the present invention solves the problems that the air in the fuel system cannot be discharged normally, the fuel cannot be filled with the...
