Abstract
The utility model discloses a novel oil pump of a diesel engine. The novel oil pump comprises a transmission gear, a main oil pump body, a driving shaft component, an oil absorption pump body and a driven shaft component, wherein a main pump oil inlet is arranged on one side of the main oil pump body; a main pump oil outlet is arranged on a flange surface of the main oil pump body attached to a mounting surface of the diesel engine body; and an auxiliary pump oil inlet and an auxiliary pump oil outlet are arranged on the two sides of the oil absorption pump body respectively. The novel oil pump disclosed by the utility model has the advantages of novel, compact and reasonable structure design, high overall output power and reliable work, and can effectively reduce the heat load born by the whole diesel engine so as to improve the overall reliability.
Description
Technical field
The utility model relates to a kind of diesel engine oil pump.
Background technique
Existing diesel engine increases technology content to improve the market competitiveness for improving constantly its output power, and constantly the direction to supercharging and charge inter cooling develops; Heat load and mechanical load that each kinematic pair of diesel engine bears are also increasing; Cause lubricated and cooling requires also increasingly highly, the application of secondary in addition oil duct cooling jet is also had higher requirement to the supply capability of diesel engine oil pump, existing diesel engine oil pump; Owing to reasons such as its structures; Pump oil ability a little less than, can not satisfy the requirement of high-power type, aspect applicability, exist certain limitation.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of the utility model is to provide, and can satisfy the diesel engine new oil pump that the high diesel engine of reinforcing degree uses.
The technical solution of the utility model is:
A kind of diesel engine new oil pump; Comprise driving gear, the main oil pump pump housing, driving axle part, the oil scavenge pump pump housing, driven shaft parts; It is characterized in that: be furnished with the main pump filler opening in the main oil pump pump housing one side, be furnished with the main pump oil outlet on the flanged surface that the main oil pump pump housing and diesel-engine body attachment face are fitted; Be furnished with auxiliary pump filler opening and auxiliary pump oil outlet respectively in oil scavenge pump pump housing both sides.
Driving axle part comprises driving shaft, dress main pump oilgear and oil scavenge pump gear on the driving shaft.
The driven shaft parts comprise driven shaft, and the first pump oilgear that dress cooperates with the main pump oilgear on the driven shaft reaches the second pump oilgear with the oil scavenge pump gear matched.
Adopt intermediate clapboard to separate between the main oil pump pump housing and the oil scavenge pump pump housing, form relatively independent oil pocket.
On the main oil pump pump housing, be furnished with overload Decompression valves parts.
The utility model structural design is novel, compact, rationally, complete machine output power height, reliable operation, and the heat load that can effectively reduce Diesel Engine Complete Machine and born, thereby the raising whole aircraft reliability.
