Furthermore, in the description of the present utility model, unless otherwise indicated, the meaning of "a plurality" is two or more.
Referring to fig. 1-5, a first embodiment discloses an oil-gas separator driving device for driving an oil-gas separator to rotate, including:
The driving wheel 1 is used for being sleeved on a central shaft 21 of the oil-gas separator. As shown in fig. 2, a plurality of grooves 11 are provided at equal intervals on the circumferential side of the driving wheel 1. Wherein the depth of the groove 11 increases from side to side in the radial direction of the drive wheel 1. As shown in fig. 2, the inner side wall of the groove 11 is a slope from left to right and from outside to inside.
Also included is a nozzle 3, as shown in fig. 1, the outlet of which nozzle 3 is oriented parallel to the radial direction of the drive wheel 1 and to the right of this radial line. The nozzle 3 sprays lubricating oil on the inclined plane in the groove 11, and the lubricating oil impacts the deepest part of the groove 11 along the inclined plane, so that the driving wheel 1 drives the central shaft 21 of the oil-gas separator to rotate. This design ensures that the nozzle drives the drive wheel in a counter-clockwise direction.
As shown in fig. 3, the inner diameter of the nozzle 3 increases gradually from the outlet end to the inlet end, and three steps, namely a first step 31, a second step 32 and a third step 33, are arranged in the nozzle, and the inner side wall of the nozzle 3 is received between the steps. In the application, the inner side walls between the steps are mutually parallel.
Alternatively, the inner side walls between the steps may be arranged horizontally, i.e. the inner diameter of the nozzle 3 between two adjacent steps is equal.
Optionally, the number of steps in the nozzle 3 is 1-4, the number of steps in the nozzle 3 can be adjusted according to the height of the driving oil pressure, the larger the driving oil pressure is, the more the number of steps is, and conversely, the smaller the driving oil pressure is, the fewer the number of steps is. At present, the number of the four steps is enough to meet the requirement of realizing pressure reduction and speed reduction of the oil-gas separator on the market.
The inner diameter of the outlet end of the nozzle 3 is 2mm, and the inner diameter of the inlet end of the nozzle 3 is 4mm.
Alternatively, the inner diameter of the outlet end of the nozzle 3, i.e. the side of the third step 33 facing away from the second step 32, may be 1.6mm to 3mm. The inner diameter of the outlet end of the nozzle 3 is adjusted according to the level of the driving oil pressure, the larger the driving oil pressure is, the smaller the inner diameter of the outlet end of the nozzle 3 is, and conversely, the smaller the driving oil pressure is, the larger the inner diameter of the outlet end of the nozzle 3 is.
Preferably, the inner diameter of the outlet end of the nozzle 3 is 2 mm-2.5 mm. The range of 2 mm-2.5 mm ensures that the outlet of the nozzle 3 is not easy to be blocked by impurities in the driving oil, the driving oil quantity is moderate, and the driving efficiency is highest. In the case where the inner diameter of the outlet end of the nozzle 3 is larger than 2.5mm, the rotation speed of the oil-gas separation device 2 increases less and less, that is, the driving efficiency decreases as the inner diameter of the outlet end of the nozzle 3 increases.
Alternatively, the inner diameter of the inlet end of the nozzle, i.e. the side of the first step 31 facing away from the second step 32, may be set to 3 mm-5 mm.
The second embodiment discloses an oil-gas separator using the above-mentioned oil-gas separator driving device, including:
The device comprises a shell 4, wherein a bearing seat is arranged in the shell 4, and a bearing is arranged in the bearing seat;
The oil-gas separation device 2 is arranged in the shell 4, and a central shaft 21 of the oil-gas separation device 2 penetrates through the bearing;
The driving wheel 1 is arranged on a central shaft 21 of the oil-gas separation device 2 in a penetrating way;
The inlet end of the nozzle 3 is communicated with a lubricating oil tank of an automobile engine.
Wherein, as shown in fig. 4, the housing 4 is provided with an inlet, a first outlet 43 and a second outlet 42. The inlet is connected with a first pipe 41, and the first pipe 41 is used for connecting an automobile engine so as to lead the gas-oil mixture generated by the operation of the engine to the oil-gas separator. The second outlet 42 is used for allowing separated liquid to flow out, the gas-oil mixture is separated by the oil-gas separation device to obtain liquid lubricating oil, and the liquid lubricating oil can be conveyed to an engine oil pan for recycling after being discharged from the second outlet 42. The first outlet 43 is used for the separated gas to flow out.
By means of the above solution, the nozzle 3 sprays liquid to hit the driving wheel 1 for rotation. Because the inner diameter of the nozzle 3 increases gradually from the outlet end to the inlet end, and the first step 31, the second step 32 and the third step 33 are arranged in the nozzle, lubricating oil sequentially collides with the first step 31, the second step 32 and the third step 33 when passing through the inner side wall of the nozzle 3, the energy of driving oil is locally lost, the pressure of the driving oil is reduced, the kinetic energy of impacting the driving wheel 1 is reduced, and therefore the rotating speed of the driving wheel 1 for driving the oil-gas separation device 2 is reduced, and the service life of the oil-gas separator is prolonged.
While the principles and embodiments of the present utility model have been described in detail in the foregoing application of the principles and embodiments of the present utility model, the above examples are provided for the purpose of aiding in the understanding of the principles and concepts of the present utility model and may be varied in many ways by those of ordinary skill in the art in light of the teachings of the present utility model, and the above descriptions should not be construed as limiting the utility model.
