Start the time that oil pressure is established.In order to reach this purpose, it is mainly the following method at present：
Fig. 1 is the schematic diagram that existing pre- oil feed pump scheme engine lubrication system circulates, and is imported and exported simultaneously in lubricating oil pump
Join a pre- oil feed pump, first start the pre- oil feed pump before an engine is started, makes the machine oil for being full of certain pressure in lubricating system,
This can accomplish that engine start oil pressure settling time is 0, and effect is fine.But this needs to increase additional oil pump, connection
The arrangements such as pipeline and control system etc., cost increases, while also being limited by arrangement space.
Fig. 2 is existing there are two the schematic diagram that check valve scheme engine lubrication system circulates, in oil cooler and
Oil filter both ends increase check valve, prevent the machine oil inside oil cooler and oil filter from existing when engine is shut down
The dirty oil return bottom case of gravity.This method, which can be reduced largely, starts oil pressure settling time, but machine is cold and machine filter
Arrangement space is limited, causes check valve size smaller, and flow resistance is larger, while check valve is in lubricating system high-pressure section, is easy
Damage.
Being disclosed in the information of the background technology part, it is only intended to increase understanding of the overall background of the invention, without answering
It has been the prior art well known to persons skilled in the art when being considered as recognizing or imply that the information is constituted in any form.

Food tray coarse filtration is drawing the machine oil in oil sump and filtering；Wherein, check valve passes through the filtered machine oil of oil suction disk coarse filtration
Oil inlet pipe is delivered in lubricating oil pump, and lubricating oil pump by the machine oil received passing through flowline, oil cooler and oil filtration
Device is delivered to main oil gallery, and main oil gallery is distributing machine oil into airframe components, and machine oil flow to oily bottom after airframe components
In shell；Wherein, machine oil being sealed in oil inlet pipe, lubricating oil pump, flowline, oil cooler and oil filter by check valve
In, machine oil is back in oil sump when preventing engine from shutting down；Wherein, when being again started up engine, lubricating oil pump can be rapid
It will be in oil delivery to airframe components.
Preferably, in above-mentioned technical proposal, airframe components are each parts for needing cooling and lubricating in engine.
Preferably, in above-mentioned technical proposal, oil cooler is cooling down machine oil.
Preferably, in above-mentioned technical proposal, oil filter is to machine oil progress refined filtration.
Compared with prior art, the present invention has the advantages that：The engine lubrication system of the present invention, only uses one
A check valve is arranged in the low-pressure section of lubricating system, at low cost, good reliability, and lubricating oil pump is efficient when engine start,
It is fast to build pressure.
Description of the drawings
Fig. 1 is the schematic diagram that existing pre- oil feed pump scheme engine lubrication system circulates.
Fig. 2 is that now there are two the schematic diagrames that check valve scheme engine lubrication system circulates.
Fig. 3 is that engine lubrication system according to the present invention circulates schematic diagram.
Specific implementation mode
Below in conjunction with the accompanying drawings, the specific implementation mode of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield range is not restricted by specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change
It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members
Part or other component parts.
As shown in figure 3, Fig. 3, which is engine lubrication system according to the present invention, circulates schematic diagram, according to the present invention
A kind of engine lubrication system of specific implementation mode comprising：Oil sump, oil suction disk coarse filtration, check valve, the machine being sequentially communicated
Oil pump, oil cooler, oil filter, main oil gallery and airframe components；Wherein, oil suction disk coarse filtration is drawing in oil sump
Machine oil and filtering；Wherein, the filtered machine oil of oil suction disk coarse filtration is delivered to by oil inlet pipe in lubricating oil pump by check valve, machine oil
Pump the machine oil received is delivered to main oil gallery by flowline, oil cooler and oil filter, main oil gallery to
Machine oil is distributed into airframe components, and machine oil is flow to after airframe components in oil sump；Wherein, check valve is to machine oil
It is sealed in oil inlet pipe, lubricating oil pump, flowline, oil cooler and oil filter, machine oil flows back when preventing engine from shutting down
Into oil sump；Wherein, when being again started up engine, lubricating oil pump can rapidly will be in oil delivery to airframe components；Wherein,
