Description
The application is divisional application, the application number of original application：2012102229247, the applying date：2012-06-29, invention
Title：The lubricant passage way and its method of work of diesel engine.
Technical field
The present invention relates to a kind of lubricant passage way and its method of work of the diesel engine for preventing machine oil from flowing back for engine.
Background technology
Engine lubrication mode, which is generally divided into, gets rid of two kinds of oil lubrication and forced draught lubrication, and it is to utilize disc to get rid of oil lubrication
Splashing machine oil in crankcase is got rid of to oil leab, if its feature be engine operating will machine oil throw away, work can
Lean on, but lubrication pressure is small, so general only use on subminiature engine.Most of engine can all use forced draught
The mode of lubrication, i.e., set lubricating oil pump in lubricant passage way, and lubricating oil pump suctions out machine oil from oil sump and presses to each of engine again
Locate lubricant passage way, this machine oil with certain pressure can guarantee that friction pair is sufficiently lubricated everywhere.But forced draught
The shortcomings that lubricating system be it is each the time that lubricating oil pump sucks out oil can lag when starting engine, often engine has been
Through operation one or two minute, lubricant passage way does not have machine oil also, longer especially for lubricating oil pump oil suction road, lubricating oil pump installation site compared with
High situation, pump oil lag time with regard to longer, at this moment if engine continues to run with and cannot get oil lubricating, will result in
Dry grinding, causes the abrasion of connecting rod bearing shell, bent axle, piston, serious situation can cause Bearing score, scuffing of cylinder bore.After engine is shut down, vertical machine
Machine oil in oil duct will be back in oil sump, and when starting engine every time, inorganic oil, lubricating oil pump need on lubricating oil pump oil suction road
By the air of oil suction road intracavitary it is all drained after can just pump out machine oil, lubricating oil pump oil suction road is longer and lubricating oil pump installation site
Higher situation, pump oil time will be very long.
The content of the invention
The technical problems to be solved by the invention be to provide it is a kind of can make machine oil quickly pump out and Rapid Implementation lubrication
The lubricant passage way and its method of work of diesel engine.
To solve the above problems, the lubricant passage way of diesel engine provided by the invention, including：Oil sump, located at the diesel engine machine
The vertical oil input channel being connected with the oil sump in body, the machine oil prevented in vertical oil input channel located at the vertical oil input channel bottom
It is back to the check valve of the oil sump, the lubricating oil pump with being connected at the top of the vertical oil input channel.Between lubricating oil pump and oil sump
Check valve is set, the machine oil in the vertical oil input channel after a shutdown can be avoided all to be back in the oil sump, i.e.,：After shutdown
Machine oil is all sealed in the vertical oil input channel using check valve, when being again started up, machine oil can be extracted into profit by lubricating oil pump rapidly
Grease way.Problem slowly is obtained when solving engine starting on machine oil, effectively solves the problems such as engine Bearing score, scuffing of cylinder bore.
As preferable scheme, the check valve includes：Tightly fit in the tube-like envelope of the vertical oil input channel bottom, set
In the valve body in shell and the sealing plate being covered in the top port of shell, in the top of the valve body and the sealing plate
Centre is connected.
As further preferred scheme, the valve body includes center valve rod, the multi-disc located at the center stem bottom is led
To flap, each flap that is oriented to is suitable to be immersed in the oil sump, with the buoyancy using machine oil to each guiding flap, to mitigate gravity
Influence to the valve body, beneficial to after lubricating oil pump is opened, the check valve can be opened easily.
External diameter at the top port of shell is less than the external diameter of the middle and lower part of shell, and the diameter of sealing plate is less than in shell
The external diameter of bottom, and the internal diameter of the top port more than shell, described in realizing and be completely covered using the less sealing plate of diameter
The purpose of the top port of shell, and then the situation that the inwall for avoiding the occurrence of sealing plate and shell rubs, it is ensured that unidirectional
The smooth unlatching of valve.
Each flap Central Symmetry that is oriented to is centrally located on valve rod；Each flap that is oriented to is suitable to and small of the inwall of the shell
Gap coordinates, so that during the check valve is opened and closed, center valve rod is suitable to axial displacement, it is ensured that check valve is opened and closed reliable
Property.
It is described to be oriented to flap and radius of the radial clearance of the outer casing inner wall less than the sealing plate and the shell
The difference of top port radius, the top end that the shell can not be completely covered to prevent the sealing plate from occurring in use
The situation of mouth, it is ensured that cut-off effect.
The lubricating oil pump is rotor-type oil pump, and the end transmission of the camshaft of rotor and diesel engine in lubricating oil pump connects
Connect.
Further, the high-pressure oil passage being connected with the high-voltage oil cavity of the lubricating oil pump is provided with oil strainer transition seat；Oil strainer
The end face of transition seat and organization seal oil chamber, being provided between the seal oil chamber and the oil sump prevents the seal oil chamber
The too high pressure limiting valve of oil pressure；Pressure limiting valve makes filtering base end face be connected with the seal oil chamber of organization with oil sump, and it is also one
Check valve, just lead to when engine oil pressure is high, engine oil pressure low hold is closed.
The method of work of the lubricant passage way of above-mentioned diesel engine, it is characterised in that including：After lubricating oil pump is opened, described vertical
Negative pressure is formed in oil input channel, check valve is opened, the vertical oil-feed that the machine oil in oil sump enters after coarse strainer coarse filtration through check valve
Road, then the dark oil duct by the twice square crossing in body enter lubricating oil pump low pressure oil pocket, the high-voltage oil cavity of lubricating oil pump
The hydraulic oil of output enters one by the end face of oil strainer transition seat and the seal oil chamber of organization；In the seal oil chamber
Machine oil introduces oil cooler through the first external oil pipe, then enters oil filter through the second external oil pipe（The oil filtration
Device is fixed on oil strainer transition seat）, then dark oil duct before the oil strainer stud introducing main bearing shell through oil filter, is reached
It is divided to oil circuit at two after main bearing shell, lubricates connecting rod bearing shell by crankshaft oil passage all the way, then returned to through spill port in machine oil pond；Another way
Oil cylinder head way is introduced by the 3rd external oil pipe and enters rocker arm shaft, rocking arm is lubricated, is then back to by pushing rod sleeve
In machine oil pond.
The present invention has positive effect relative to prior art：Being set between lubricating oil pump and oil sump for the present invention prevents
The check valve of machine oil backflow, when solving engine starting on machine oil slow problem, effectively solve the drawing of engine Bearing score
The problems such as cylinder.The sealing plate is formed by sheet metal punching, and valve body employs nylon material to mitigate its weight.This check valve
The deadweight of valve body and sealing plate be make use of to be close to shell upper surface, so that machine oil more than shell is blocked without flowing
In oil return drain pan.Substantially in oil sump, there is buoyancy in machine oil to valve body with unidirectional valve position, can be by when making the first oil suction of lubricating oil pump
The buoyancy overcomes the gravity of valve body and sealing plate, machine oil is suctioned out, machine oil is all sealed in oil using check valve after shutdown
In road, machine oil can be to be extracted into oil leab by lubricating oil pump soon when being again started up.
