Abstract
The invention provides a dry oil pan system preventing oil returning. The system comprises an engine, an oil pan, an oil pump, an oil tank, an oil tank oil discharging pipe and an oil tank oil returning pipe. The highest position of the oil tank oil returning pipe is higher than that highest level position of the oil tank; the oil tank oil discharging pipe is in an 'n' shape and is provided with an exhaust valve. On the premise of maintaining an original oil circulating system, the oil tank oil returning pipe is redesigned, the exhaust valve is arranged additionally, after the engine is shut down, the oil levels in the engine and oil pan can be maintained in low positions.
Description
Technical field
The invention belongs to engine sump tank technical field, especially relate to a kind of dry sump system preventing machine oil from refluxing, relate to a kind of by improving conventional machine fuel tank outlet pipe structure form and installing the dry sump system of bleed valve more specifically.
Background technique
Engine sump tank is divided into dry sump and wet sump, and dry sump is used for engine of armored vehicle short transverse being had to particular/special requirement, and wet sump is used for civilian vehicle motor.For the motor adopting dry sump, its engine oil recycle system mainly comprises engine body, oil sump, oil pump, sump and all kinds of pipeline.Due to reasons such as sump layout and machine oil froth breakings, most of sump adopts the form of " upper entering and lower leaving ", and namely the import of sump oil inlet pipe is arranged in the top of sump, and the outlet of sump outlet line is arranged in the below of sump.In engine operation process, the pumping ability due to oil pump dump pump is greater than the pumping ability of oil pump oil-pressing pump, and the machine oil liquid level of engine interior can be made to remain on lower position.When after engine stoping operation, because sump machine oil liquid level is far above engine interior machine oil liquid level, according to law of connected vessels, the machine oil in sump slowly can enter engine body by sump outlet line and oil pump, until both liquid levels are substantially contour.
Due to the Special use demand that armored vehicle etc. is equipped, vehicle standing, multifrequency time maintenance and the multiple situations such as maintenance of changing according to the season for a long time can be there is.Too high and the long-time immersion of engine interior machine oil liquid level, directly can cause the inefficacy of all kinds of Sealing; If when vehicle carries out the operations such as hill start, the too high generation likely causing significant troubles such as taking blame for others of machine oil liquid level; In addition, in the maintenance process of reality, due to the backflow phenomenon of machine oil, the liquid level position of sump can be lower than actual conditions, often there will be operator and find repeatedly the accidents such as the sump swell that filling machine oil causes; When engine maintenance, the machine oil of engine body inside is too much, and drain the oil in process at oil sump, machine oil wasting phenomena is also more serious.
Therefore, after design source is run for engine stop, machine oil reflux problem controls, and for motor optimization design, improves motor " six property ", avoids the generation of significant troubles such as taking blame for others, have important practical significance.
Summary of the invention
The present invention is directed to the problems referred to above; a kind of dry sump system preventing machine oil from refluxing is provided; this system is under the prerequisite not changing engine oil circulating system in the past; adopt and improve sump outlet pipe structure form; and install the mode of bleed valve additional, well solve dry sump motor and prevent machine oil from flowing back to the object of internal body after a shutdown.
The technical solution used in the present invention is:
The dry sump system preventing machine oil from refluxing, comprises engine body, oil sump, oil pump, sump, and sump oil outlet tube and sump return tube; The extreme higher position of described sump return tube is higher than high liquid level (HLL) position most in sump, and described sump oil outlet tube adopts " several " character form structure, and is provided with bleed valve thereon.
The present invention changes " one " font (referring to Fig. 1) of existing sump oil outlet tube, adopt " several " character form structure, and on pipeline, bleed valve is installed, for the motor of assembling dry sump, in its running, the oil-pressing pump of oil pump passes through sump outlet line by the machine oil suction body main oil gallery in sump, machine oil is by after each lubrication node, flow back to oil sump before and after oil sump, pass through sump return line suction sump by oil pump dump pump again, complete lubricating oil system circulation.While engine stoping operation; the bleed valve be arranged on oil pump outlet pipe road is opened; air is from top ingress engine fuel tank outlet line; according to law of connected vessels; make the machine oil of higher liquid level position in sump no longer be back to engine body inside, reach the object controlling internal body machine oil liquid level position after shutting down.
As the preferred embodiment of the present invention, the highest position of described sump oil outlet tube is provided with the erection support installing described bleed valve.
As the mode of execution that the present invention is more preferably, described erection support is positioned at the middle part of the extreme higher position of described sump oil outlet tube.
As the preferred embodiment of the present invention, described sump oil outlet tube Integrated design is in the inside of the side plate of described sump.
As the preferred embodiment of the present invention, described bleed valve is but is not limited to the one in solenoid valve, mechanical valve, pneumatic valve.
As the preferred embodiment of the present invention, described bleed valve is associated with described engine body running state, and when engine body runs, bleed valve is in closed condition; When engine body is shut down, bleed valve is in open mode.
The advantage that the present invention has and good effect are:
The present invention is under the prerequisite not changing original engine oil recycle system, by improving the design of sump oil outlet tube, install the form of bleed valve additional, can be after engine stop, the machine oil liquid level in engine body and oil sump is made to remain on lower position, meet the user demand of fast assembling-disassembling in motor " six property " requirement, reduce the possibility that each Sealing in engine body occurs because long-time machine oil soaks to lose efficacy, avoid because after motor shutdown, machine oil liquid level is too high, start is taken blame for others again, or due to misoperation, repeatedly load the generation of the significant troubles such as the sump swell that causes of machine oil.
