Abstract
The utility model discloses a novel diesel engine breather. The novel diesel engine breather comprises a breather shell and a breather cover which are assembled together. A seal ring is disposed between the breather shell and the breather cover. The breather cover is fixed on the breather shell through a butterfly nut. An upper partition, a steel wire filter screen and a lower partition are sequentially disposed in the breather shell from top to bottom. A spacer bush is disposed between the upper partition and the breather cover. A gas outlet pipe is arranged on the lateral wall of the breather shell. A gas inlet pipe is connected to the lower end of the breather shell. A mounting flange provided with a cavity inside is connected to the other end of the air inlet pipe. A partition is welded to the inner surface of the cavity of the mounting flange. The partition and the cavity of the mounting flange forms a maze structure. By the novel diesel engine breather, engine oil can be prevented from being discharged from the inner cavity of the diesel engine along with gas, work reliability of the diesel engine is guaranteed, engine oil consumption is reduced, and application cost is saved.
Description
Technical field
The utility model belongs to diesel engine technologies field, is specifically related to a kind of Novel diesel aspirating device.
Background technique
Resuscitation apparatus is the functional part being installed on diesel-engine body, ensure diesel engine crankcase inside and outside air pressure balance, and prevent a kind of device that machine oil is altered outward, diesel engine in the course of the work, in its crankcase, be full of the gas of high pressure oil-containing, generally by Diesel Engine Breather, high pressure oil gas is separated and discharged, thereby play pressure release effect, guarantee diesel engine is normally worked.Diesel Engine Breather in the past, it is by the lubricating oil separation in high pressure oil gas and be back to fuel tank, and isolated gas directly drains into atmosphere, because gas is mainly waste gas and unburnt fuel vapor, directly discharge not only can cause environmental pollution, and machine oil discharges with gas from diesel engine inner chamber, increase the consumption of machine oil, improve user cost.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of Novel diesel aspirating device that reduces consumption of lubricating oil, ensures diesel engine work reliability.
The technical solution of the utility model is:
A kind of Novel diesel aspirating device, comprise the ventilator housing and the resuscitation apparatus lid that fit together, between described ventilator housing and resuscitation apparatus lid, be provided with seal ring, described resuscitation apparatus lid is fixed on ventilator housing by wing nut, it is characterized in that: in described ventilator housing, be provided with successively from the top down upper clapboard, Steel net, lower clapboard, between described upper clapboard and described resuscitation apparatus lid, be provided with spacer, the sidewall of described ventilator housing is provided with resuscitation apparatus steam outlet pipe, the lower end of described ventilator housing is connected with resuscitation apparatus suction tude, the other end of described resuscitation apparatus suction tude is connected with mounting flange, in described mounting flange, be provided with cavity, the cavity internal surface of described mounting flange is welded with dividing plate, the cavity of described dividing plate and described mounting flange forms labyrinth structure.
Further, described resuscitation apparatus suction tude is fixed on supporting frame, and described resuscitation apparatus steam outlet pipe uses clip to fix.
Further, described Steel net comprises Composite Steel silk screen.
The beneficial effects of the utility model:
Diesel Engine Breather of the present utility model can prevent that machine oil from discharging with gas from diesel engine inner chamber, has ensured diesel engine work reliability, not only reduces the consumption of machine oil, has saved user cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic internal view of the utility model mounting flange.
Embodiment
As depicted in figs. 1 and 2, a kind of Novel diesel aspirating device of the present utility model, comprise the ventilator housing 8 and the resuscitation apparatus lid 12 that fit together, between described ventilator housing 8 and resuscitation apparatus lid 12, be provided with seal ring 11, described resuscitation apparatus lid 12 is fixed on ventilator housing 8 by wing nut 13, it is characterized in that: in described ventilator housing 8, be provided with successively from the top down upper clapboard 10, Steel net 9, lower clapboard 7, between described upper clapboard 10 and described resuscitation apparatus lid 12, be provided with spacer 14, the sidewall of described ventilator housing 8 is provided with resuscitation apparatus steam outlet pipe 4, the lower end of described ventilator housing 8 is connected with resuscitation apparatus suction tude 3, the other end of described resuscitation apparatus suction tude 3 is connected with mounting flange 1, in described mounting flange 1, be provided with cavity, the cavity internal surface of described mounting flange 1 is welded with dividing plate 2, described dividing plate 2 forms labyrinth structure with the cavity of described mounting flange 1.
Further, described resuscitation apparatus suction tude 3 is fixed on supporting frame 5, and described resuscitation apparatus steam outlet pipe 4 uses clip 6 fixing.
Further, described Steel net 9 comprises Composite Steel silk screen.
Resuscitation apparatus working principle: when diesel engine work, because there being certain gap between piston ring and cylinder liner, thereby part high temperature, pressurized gas are from firing chamber internal leakage to crankcase, cause the pressure in crankcase to raise, working resistance increases, and then causes diesel engine not work normally; For ensureing diesel engine crankcase inside and outside air pressure balance, this resuscitation apparatus is installed on body with the bolts of two, high temperature, pressurized gas are by discharges such as mounting flange 1, resuscitation apparatus suction tude 3, ventilator housing 8, Steel net 9, upper clapboard 10, resuscitation apparatus steam outlet pipes.Discharge with high temperature, pressurized gas for preventing machine oil that (machine oil is under the stirring of bent axle and piston crank mechanism, form mixed oil and gas with high temperature, pressurized gas), this resuscitation apparatus is provided with twice anti-channeling oil device, first anti-channeling oil device is labyrinth structure, formed by mounting flange 1 and anti-channeling oil dividing plate 2, the mixed gas that concentration is lower can only detour and flow into resuscitation apparatus steam outlet pipe 3 from less gap, and concentration flows back to by stopping of dividing plate 2 compared with high mixed gas; Second jettison gear is cold filtration structure, the lower mixed gas of concentration through the filtration of Steel net 9, upper clapboard 10 and cooling after, gas through spacer 14, resuscitation apparatus air-out hose and discharge, flows back to crankcase through lower clapboard 7, resuscitation apparatus breathing pipe 3, resuscitation apparatus flange 1 etc. after machine oil is cooling.
