AI Technical Summary

Technical Problem

The pads of existing high-pressure oil pumps only serve as support, and the lubrication of the high-pressure oil pump requires drilling holes and oil extraction from the cylinder block, which is inconvenient to operate and may cause damage to the cylinder block.

Method used

A high-pressure oil pump pad is designed, including through holes, fixed holes, annular grooves and sealing rings. The engine oil lubrication is achieved through the protruding end and the oil-through blind hole, simplifying the installation and lubrication process of the high-pressure oil pump.

Benefits of technology

The high-pressure oil pump is achieved simultaneously fixing and lubrication, saving engine space, simplifying the installation and maintenance process, and avoiding the problems of cylinder block damage and the length of the oil pipe.

Abstract

The present invention discloses a high-pressure oil pump pad, a high-pressure oil pump lubrication system and a vehicle, which belong to the high-pressure common rail supply system of a diesel engine. It is used for the fixed connection and lubrication function of the high-pressure oil pump of a diesel engine. The structure of the present invention is simple and compact, and one structure can simultaneously realize the installation, fixation and lubrication of the oil pump. It is easy to process, low in cost and easy to assemble, avoiding the difficult implementation of lubrication methods, and can realize the installation and lubrication of all diesel engine high-pressure oil pumps. It is more space-saving and easy to maintain and disassemble. The use of the high-pressure oil pump pad of the present invention saves space in the engine, makes the layout more reasonable and convenient, and has good maintainability and good effects. The oil pump pad can be deformed into different shapes according to actual conditions.
