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 the lubricant passage way and its method of work of a kind of diesel engine for preventing machine oil backflow for electromotor.
Background technology
Engine lubrication mode 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 electromotor operating will machine oil throw away, work can
Lean on, but lubrication pressure is little, so general only use on subminiature electromotor.Most of electromotor can all use forced draught
The mode of lubrication, i.e., arrange lubricating oil pump in lubricant passage way, and lubricating oil pump suctions out machine oil from oil sump and presses to each of electromotor again
Place's lubricant passage way, this machine oil with certain pressure can guarantee that friction pair is sufficiently lubricated everywhere.But forced draught
When the shortcoming of lubricating system is to start electromotor every time, the time that lubricating oil pump sucks out oil can be delayed, and often electromotor has been
Jing run one or two minute, the also no machine oil of lubricant passage way is longer especially for lubricating oil pump oil suction road, lubricating oil pump installation site compared with
High situation, pump oil are lag time just longer, if at this moment electromotor 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 cause Bearing score, scuffing of cylinder bore.After electromotor is shut down, vertical machine
Machine oil in oil duct will be back in oil sump, and when every time starting electromotor, lubricating oil pump oil suction road inorganic oil, lubricating oil pump are needed
Machine oil can just be pumped out after will be the air of oil suction road intracavity all drained, 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 problem to be solved 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 the diesel engine that the present invention is provided, including：Oil sump, located at the diesel engine machine
The vertical oil input channel being connected with the oil sump in body, located at the machine oil prevented in vertical oil input channel of the vertical oil input channel bottom
It is back to the check valve and the lubricating oil pump being connected at the top of the vertical oil input channel of the oil sump.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, when being again started up using check valve, machine oil can be extracted into profit rapidly by lubricating oil pump
Grease way.A slow difficult problem is solved when electromotor is started on machine oil to obtain, the problems such as effectively solve electromotor Bearing score, scuffing of cylinder bore.
Used as preferred scheme, the check valve includes：Tightly fit in the tube-like envelope of the vertical oil input channel bottom, set
In the valve body and the sealing plate that is covered in the top port of shell of inside the shell, the top of the valve body and the sealing plate in
Centre is connected.

The external diameter of bottom, and the internal diameter of the top port more than shell, it is described to realize being completely covered using the less sealing plate of diameter
The purpose of the top port of shell, and then sealing plate is avoided the occurrence of with the situation that the inwall of shell occurs to rub, it is ensured that it is unidirectional
The smooth unlatching of valve.
Each flap centrosymmetry that is oriented to is centrally located on valve rod；Each flap that is oriented to is suitable to and little 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 the reliability of check valve opening and closing
Property.
The radial clearance for being oriented to flap and the outer casing inner wall less than the sealing plate radius and the shell
, there is the top end that the shell can not be completely covered in use to prevent the sealing plate in the difference of top port radius
The situation of mouth, it is ensured that cut-off effect.
The lubricating oil pump is that the end transmission of the camshaft of rotor-type oil pump, the rotor in lubricating oil pump and diesel engine 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 connect with oil sump with the seal oil chamber of organization, and it is also one
Check valve, just leads to when engine oil pressure is high, and 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 include：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 Jing check valves are entered Jing after coarse strainer coarse filtration of the machine oil in oil sump
Road, then the dark oil duct of 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 is into one by the end face of oil strainer transition seat and the seal oil chamber of organization；In the seal oil chamber
The first external oil pipes of machine oil Jing introduce oil cooler, and then the second external oil pipes of Jing enter oil filter（The oil filtration
Device is fixed on oil strainer transition seat）, then the front dark oil duct of the oil strainer stud introducing main bearing shell of Jing oil filter, reaches
Being divided to oil circuit at two after main bearing shell, connecting rod bearing shell being lubricated through crankshaft oil passage all the way, then Jing spill ports are returned in machine oil pond；Another road
Oil cylinder head way is introduced by the 3rd external oil pipe and rocker arm shaft is entered, 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：Arranging between lubricating oil pump and oil sump for the present invention is prevented
The check valve of machine oil backflow, solves the difficult problem for obtaining on machine oil when electromotor is started slowly, effectively solves the drawing of electromotor Bearing score
The problems such as cylinder.The sealing plate is to be formed by sheet metal punching, and valve body employs nylon material to mitigate its weight.This check valve
Make use of valve body and sealing plate deadweight being 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 to valve body in machine oil with unidirectional valve position, can be by when making the first oil suction of lubricating oil pump
The buoyancy come overcome valve body and sealing plate gravity, machine oil is suctioned out, after shutdown, machine oil oil is all sealed in using check valve
In road, when being again started up, lubricating oil pump just can be extracted into oil leab machine oil soon.
