Problems solved by technology

[0004] In the above-mentioned technology, the fuel pump 3 is a rigid structure, which is restricted by the associated assembly dimensions when the fuel pump 3 is assembled. The existence of vibration during work may easily cause cracks in the welded part of the lubricating oil pipe 2 and the ball head, resulting in oil leakage, causing the fuel pump 3 to fail to work and bring potential safety hazards

Abstract

The invention discloses a novel-structure fuel pump lubricating oil pipe. According to the novel-structure fuel pump lubricating oil pipe, a rigid structure in the prior art is redesigned into a rigidity-flexibility-combined structure; on the one hand, restraints in relevant assembly dimensions during fuel pump assembly are overcome, and the condition that a lubricating oil pipe body and ball ends are under the combined action of tension, pressure and torsion is avoided during assembling; on the other hand, influences caused by engine vibrations can be avoided, and a buffering and vibration-absorption function can be achieved; meanwhile, high costs due to the fact that rigid structure lubricating oil pipes made of new materials are utilized for the sake of technological improvements in order to avoid influences caused by stress and vibrations can also be avoided. By means of applications and experimental verifications, the novel-structure fuel pump lubricating oil pipe has no pipe body cracking and oil leakage during an application process, has a structure better than that in the prior art and can guarantee the normal operation and safety performance of a fuel pump.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a novel structure fuel pump lubricating oil pipe. Background technique [0002] When the engine fuel pump is working normally, it needs external lubricating oil to lubricate its mechanical parts in time, so that the mechanical parts of the fuel pump can work better and reduce mechanical wear. It plays the role of transferring heat to the mechanical part in the fuel pump and reducing the working heat of the mechanical part in the fuel pump. [0003] Figure 1 shows the connection mode of the engine fuel pump in the prior art and the lubricating oil pipe structure of the intermediate pipeline fuel pump that provides lubrication. One side of the fuel pump 3 is fixed on the gear chamber 7 through the transition connection flange 5 and the bolt 6. At the same time, the lower end is fixed on the cylinder block 1 by the bolt 9 through the bracket 8, one end of the lubricating oil pipe 2...
