Detailed Description
The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings for a purpose of helping those skilled in the art to more fully, accurately and deeply understand the concept and technical solution of the present invention and to facilitate its implementation.
As shown in fig. 1 to 6, the present invention provides an engine ventilation oil return structure, which includes a lubricant tank connected to an engine cylinder 1 through an oil return pipe 5, an oil pump 4, and an oil inlet pipe 7 connected to the lubricant tank and the oil pump 4, wherein the lubricant tank includes a lubricant tank body 15, a lubricant tank cover 14 disposed on the lubricant tank body 15, a filter screen 16 disposed inside the lubricant tank body 15, and an oil suction pipe 17 disposed inside the filter screen 16 and used for guiding lubricant oil filtered by the filter screen 16 to the oil inlet pipe 7, and a lowest position on the engine cylinder 1 is disposed at an oil return port connected to the oil return pipe 5.
Specifically, as shown in fig. 1 to 4, the lubricating oil tank 15 is a cylinder with an open upper end and a hollow interior, the lubricating oil tank cover 14 is connected to the upper end of the lubricating oil tank 15, a sealing ring is disposed between the lubricating oil tank cover 14 and the lubricating oil tank 15 for sealing, the filter screen 16 is fixedly disposed in the inner cavity of the lubricating oil tank 15, the oil suction pipe 17, the filter screen 16 and the lubricating oil tank 15 are coaxially disposed, the oil suction pipe 17 is located at the center of the interior of the filter screen 16 and the oil suction pipe 17 is connected to the oil inlet pipe 7, the upper end of the oil suction pipe 17 penetrates through the lubricating oil tank cover 14 and then is connected to the oil inlet of the oil inlet pipe 7, the oil suction pipe 17 is fixedly connected to the lubricating oil tank cover 14, and the oil outlet of. An oil return pipe joint 9 for guiding lubricating oil from an oil return pipe 5 to the inside of the lubricating oil tank body 15 is arranged on the lubricating oil tank cover 14, an oil inlet of the oil return pipe 5 is connected with an oil return port arranged at the bottom of the engine cylinder body 1, and an oil outlet of the oil return pipe 5 is connected with the oil return pipe joint 9. An air outlet pipe 8 for exhausting air outwards is arranged on the lubricating oil tank cover 14, and the air outlet pipe 8 is communicated with the inner cavity of the lubricating oil tank body 15.
An oil return port is arranged at the lowest position of the engine cylinder body 1, and lubricating oil returns to the bottom of the engine under the action of gravity and then enters a lubricating oil tank through an oil return pipe 5. The engine crankcase gas and the engine return oil share an oil return passage-oil return pipe 5. After returning to the lubricating oil tank, the lubricating oil is roughly filtered by the filter screen 16, enters the oil pump 4 through the oil inlet pipe 7 under the action of the oil pump 4, is cooled by the oil cooler 2, is filtered by the oil filter 3, and enters the engine, so that the continuous circulation of the lubricating oil is realized. After the gas enters the lubricating oil tank, the lubricating oil returns to the bottom of the lubricating oil tank through the oil-gas separation effect of the labyrinth, and the gas is discharged along with the gas outlet pipe 8.
Because the crankcase gas and the lubricating oil share the oil return channel, the crankcase gas continuously discharged in the running process of the engine leads the internal pressure of the engine to be continuously increased, and forms pressure difference with the external connection to provide power for the lubricating oil to enter the lubricating oil tank. When the differential pressure reaches balance, the return oil reaches balance, and continuous circulation of the lubricating oil is realized. Because the lubricating oil in the engine returns to the lubricating oil tank in time under the action of the pressure of the crankcase, the problem that the liquid level is stirred by a crankshaft connecting rod is avoided, and the purpose of reducing the oil consumption of the engine is realized.
Therefore, the engine does not need an oil pan, and the purposes of reducing the height of the engine and realizing compact arrangement are achieved. The lubricating oil tank body 15 is provided with a lubricating oil tank fixing hole 12 for a bolt to pass through, and the lubricating oil tank can be arranged at any position, so that the matching performance of the whole machine is high.
The filter screen 16 is arranged in the lubricating oil tank, the filter screen 16 is matched, clamped and fixedly connected with the lubricating oil tank cover 14 and the lubricating oil tank body 15, a groove for embedding the upper end of the filter screen 16 is formed in the lubricating oil tank cover 14, and a groove for embedding the lower end of the filter screen 16 is formed in the lubricating oil tank body 15, so that the filter screen 16 is accurately positioned. After the engine return oil enters the lubricating oil tank, the filter screen 16 performs rough filtration on the return oil, so that the circulation of engine wear is avoided, and the purpose of protecting the oil pump 4 is achieved. After the return oil and the crankcase gas pass through the filter screen 16, the preliminary separation can be realized.
As shown in fig. 1 to 5, the strainer 16 is a cylindrical structure with a hollow inside, and the oil suction pipe 17 is disposed inside the strainer 16. The lubricant oil after rough filtration passes through the oil suction pipe 17 and enters the oil inlet pipe 7 and the oil pump 4. The tank lid 14 and the baffle 13 form a labyrinth structure. Crankcase gas gets into the maze by air inlet 19, and under the effect of external pressure differential, oil gas flows at a high speed in the inside maze along the circumferencial direction, sets up a plurality of fender muscle and oil-out in the tank lid 14 of lubricating oil, and high-speed oil gas is run into and is kept off the muscle after, and oil is separated and is handled, discharges along the oil-out, gets back to the lubricating oil tank bottom, and gas is discharged through outlet duct 8.
As shown in fig. 1 to 4, the fuel tank case 15 includes a large diameter portion and a small diameter portion connected to a lower end of the large diameter portion and located below the large diameter portion, the large diameter portion having a diameter larger than that of the small diameter portion, a strainer 16 disposed inside the large diameter portion and the small diameter portion, and a fuel tank cover 14 connected to an upper end of the large diameter portion. The major diameter portion and the minor diameter portion of the lubricating oil tank body 15 are both of a cylindrical structure with a hollow inner portion, the major diameter portion and the minor diameter portion are coaxially arranged, the lubricating oil tank cover 14 is fixedly connected with the upper end of the major diameter portion, and the lower end of the minor diameter portion is closed. A portion of the screen 16 is located in the inner cavity of the large diameter portion and another portion of the screen 16 is located in the inner cavity of the small diameter portion. The lower end of the oil suction pipe 17 is provided with an oil inlet, the upper end of the oil suction pipe 17 is an oil outlet, the oil inlet of the oil suction pipe 17 is close to the bottom of the lubricating oil tank, and the vertical distance between the oil inlet of the oil suction pipe 17 and the bottom surface of the small-diameter part of the lubricating oil tank body 15 is smaller than the vertical distance between the oil inlet of the oil suction pipe 17 and the upper end of the small-diameter end. Therefore, the lubricating oil tank is designed to be of a structure with a large upper part and a small lower part, the oil suction pipe 17 is arranged at the central position of the lubricating oil tank, and due to the fact that the bottom area of the lubricating oil tank is small, when the lubricating oil tank is inclined at a large angle, only a small amount of lubricating oil is needed inside the lubricating oil tank, the oil inlet at the lower end of the oil suction pipe 17 can be covered, and the problem of air suction is avoided. Therefore, the purpose of ensuring the large-angle inclination of the engine is achieved on the premise of not increasing the filling amount of lubricating oil.
As shown in fig. 1 to 4, a liquid level observation window 10 is provided in the fuel tank body 15.
