Abstract
The utility model discloses an internal combustion engine oil pressure-electric starting device, which comprises a pipeline machine oil pump 3, an original machine engine oil pump 2, a pressure limiting valve 1, a one-way valve 8, an engine oil collection filter 5, and a pressure relay 6, wherein, the pipeline machine oil pump 3 is connected in parallel with the original machine engine oil pump 2, the pipeline machine oil pump 3 and an oil inlet of the original machine engine oil pump 2 are connected with the engine oil collection filter 5 by an oil inlet pipe 4, an oil outlet of the pipeline machine oil pump 3 is connected with the pressure relay 6 by an oil outlet pipe 7, an oil outlet of the original machine engine oil pump 2 is connected with a main oil passage 9 by an oil outlet pipe 10, the one-way valve 8 is arranged between the pipeline machine oil pump 3 and the original machine engine oil pump 2, and the pressure limiting valve 1 is arranged on the oil inlet pipe 4. Due to the adoption of the structure, the utility model firstly starts the pipeline machine oil pump when the internal combustion engine is started, each lubricating point can be filled with lubricating oil, and lubricating oil films can be ensured to form among all relative motion components before the internal combustion engine is started; thereby, the wear abrasion of the relative motion components in the starting moment can be reduced, and the service life of the internal combustion engine is prolonged.
Description
Technical field
The utility model relates to a kind of internal combustion (IC) engine lubricating oil pressure unit, particularly a kind of internal-combustion engine oil pressure-electronic starting drive.
Background technique
At present the Starting mode of internal-combustion engine has: form such as manual, pneumatic and electronic, commonly used is motor start-up.Its working procedure is: the operator opens key operation, by the circuit of relay closes starting motor, is fixed on the gear ring starting apparatus combustion engine of internal combustion engine flywheel dish periphery by the small gear drive of starting motor front end.Internal-combustion engine is turned round to automatic by state of rest, no matter the startability of internal-combustion engine how well, all must be through an of short duration time, during this, because of the lubricating system of internal-combustion engine is not worked as yet, the relative movement component surface can not form oil film, and the metal surface will take place directly to rub, especially in moment that start-up course begins, frictional resistance perhaps can be very big, make the part time job surface cause unnecessary wearing and tearing, and will increase starting resistance, influence the starting performance of internal-combustion engine.
Summary of the invention
The purpose of this utility model will provide a kind of internal-combustion engine oil pressure-electronic starting drive exactly; it can overcome above-mentioned the deficiencies in the prior art effectively; when the relative movement component surface does not produce relative movement as yet; form oil film therebetween; make internal-combustion engine in the moment that starts beginning; the relative movement part just moves under the protection of oil film, alleviates component wear thereby reach, and prolongs the internal-combustion engine purpose in working life.
The purpose of this utility model is achieved in that a kind of internal-combustion engine oil pressure-electronic starting drive, comprise pipe machine oil pump 3, former machine oil pump 2, pressure-limit valve 1, one-way valve 8, sump strainer 5 and pressure relay 6, pipe machine oil pump 3 is in parallel with former machine oil pump 2, the filler opening of pipe machine oil pump 3 and former machine oil pump 2 all passes through oil inlet pipe 4 and links to each other with sump strainer 5, the oil outlet of pipe machine oil pump 3 links to each other with pressure relay 6 by oil outlet tube 7, the oil outlet of former machine oil pump 2 links to each other with main oil gallery 9 by oil outlet tube 10, between pipe machine oil pump 3 and the former machine oil pump 2 one-way valve 8 is set, pressure-limit valve 1 is set on the oil inlet pipe 4.
Owing to adopt said structure, before internal combustion engine start, give between each relative movement component of internal-combustion engine with the pipe machine oil pump earlier and form lubricant film, after oil pressure reaches certain value, the make contact of pressure relay, the starting motor of internal-combustion engine starts, final cranking internal combustion engine.After the internal combustion engine start, the pipe machine oil pump quits work automatically, and the former machine oil pump of internal-combustion engine is started working, and high pressure oil is subjected to the control of one-way valve and can enter in the pipe machine oil pump, thereby reach the wearing and tearing that alleviate the relative movement part, the purpose that prolongs the working life of internal-combustion engine.
Description of drawings
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a principle schematic of the present utility model.
Fig. 1 double as Figure of abstract.
Embodiment
As shown in Figure 1, a kind of internal-combustion engine oil pressure-electronic starting drive, comprise pipe machine oil pump 3, former machine oil pump 2, pressure-limit valve 1, one-way valve 8, sump strainer 5 and pressure relay 6, pipe machine oil pump 3 is in parallel with former machine oil pump 2, the filler opening of pipe machine oil pump 3 and former machine oil pump 2 all passes through oil inlet pipe 4 and links to each other with sump strainer 5, the oil outlet of pipe machine oil pump 3 links to each other with pressure relay 6 by oil outlet tube 7, the oil outlet of former machine oil pump 2 links to each other with main oil gallery 9 by oil outlet tube 10, between pipe machine oil pump 3 and the former machine oil pump 2 one-way valve 8 is set, pressure-limit valve 1 is set on the oil inlet pipe 4.
In the lubrication system of internal-combustion engine, install one by direct current motor driven pipe machine oil pump 3, the original oil pump 2 of this oil pump and internal-combustion engine is in parallel, during internal combustion engine start, after ignition key inserts switch, forward earlier first gear clockwise to, promptly connect the firing circuit (for petrol engine) of internal-combustion engine, continue to forward to clockwise second gear again, then connect the circuit of pipeline oil pump 3, Oil pump electrical machinery is started working, lubricant oil enters pipe machine oil pump 3 from oil inlet pipe 4, the lubricant oil that comes out from pipe machine oil pump 3 enters internal-combustion engine main oil gallery 9 through one-way valve 8, this moment, the oil pressure of internal-combustion engine whole lubricating system began to raise, and made between the relative movement component and formed oil film; When treating that oil pressure reaches certain value, pressure relay 6 is connected engine starting traction relay circuit, and the starter motor of internal-combustion engine is started working, starting apparatus combustion engine; Too high pressure oil is opened pressure-limit valve 1, makes oil pressure recover normal.Treat after the internal combustion engine start, the operator looses one's grip, ignition key is promptly got back to first gear automatically under the effect of spring, pipe machine oil pump 3 quits work because of losing power supply, the former machine oil pump 2 of internal-combustion engine is started working, but is subjected to the restriction of one-way valve 8 from the lubricant oil that the former machine oil pump 2 of internal-combustion engine is come out, can the oil duct of flow ipe oil pump 3 in, too high oil pressure is opened pressure-limit valve 1, makes oil pressure recover normal.
