The utility model discloses simple structure, convenient to use is fixed with through the installation of this oil pump end cover and up -to -date style oil pump, great improvement holisticly produce oil and spray the effect to further improvement the lubricated effect of engine.
Description
Technical field
The utility model relates to a kind of lubricating oil pump, particularly relate to a kind of diesel engine oil pump cover。
Background technology
Electromotor is the heart of automobile, and the accessory drive chain system of electromotor is the important component part of engine structure。The functional reliability of electromotor is had important impact by the functional reliability of the accessory drive chain system of electromotor。In order to ensure the functional reliability of the accessory drive chain system of electromotor, it usually needs be arranged around an oil injection nozzle for chain and correlated parts thereof are lubricated at this chain。Oil injection nozzle is internal to communicate with the machine oil oil duct of electromotor。When the engine runs, the machine oil that lubricating oil pump pumps arrives oil injection nozzle by oil duct, on nozzle, design has the spray orifice of very small diameter, machine oil is ejected on chain by spray orifice, the friction surface of the parts such as chain, sprocket wheel, guide plate, tensioning plate is lubricated, to meet the requirement of engine chain system functional reliability。
But the most fuel-displaced effect of existing jerk pump is poor, its main cause is that the most overall structure of pump cover is comparatively single with its working method, and the fuel-displaced effect that will improve oil pump could effectively improve the fuel-displaced effect of lubricating oil pump only by the internal structure and corresponding oil pump cover that change oil pump。
Utility model content
This utility model purpose is to provide a kind of diesel engine oil pump cover, and it can efficiently solve problem existing in background technology。
In order to solve problem existing in background technology, it comprises pump cover 1, the inner side of this pump cover 1 vertically extends the first boss 2 and the second boss 3 and the 3rd boss 4 being symmetrical arranged and docking with pump case respectively inwards, wherein, the second described boss 3 and the 3rd boss 4 are positioned at the outside of the first boss 2, it is provided above the 4th boss 5 between two the first boss 2, it is provided with the 5th boss 6 below, the two ends place of described pump cover 1 bottom surface is respectively arranged with the first composition surface 7 and second docked with pump case and engages 8, the medial surface of this first composition surface 7 and the second joint 8 flushes with the inner side edge of pump cover 1；
The first described boss 2 and the second boss 3 and the 3rd boss 4 offer the centre bore of through setting；
The first described composition surface 7 and the second joint 8 offer the centre bore for docking with pump case end。
Owing to have employed above technical scheme, this utility model has the advantages that simple in construction, easy to use, is mounted with by the machine oil pump end cap and up-to-date lubricating oil pump, it is greatly improved the fuel-displaced and jeting effect of entirety, thus further improve the lubricant effect of electromotor。
