Respiratory organ is as the critical component of crankcase ventilation system, for ensureing that engine health operating serves important function.But respiratory organ bleed is serious, oil consumption is big, and crankcase waste gas pressure is high, has had a strong impact on the performance of electromotor.
Additionally, due to crankcase waste gas aerofluxus is not smooth, the moisture in waste gas can make lubricating oil blushing occur, thus affecting the lubrication of each parts, accelerating concentrated wear, affecting the service life of electromotor.
Summary of the invention
The present invention is contemplated to solve that respiratory organ bleed is serious, oil consumption big, crankcase waste gas pressure is high, affect the problem of engine performance, and crankcase waste gas aerofluxus is smooth, moisture in waste gas makes lubricating oil turn white, affect the lubrication of each parts, quickening concentrated wear, the problem that affects service life of aeroengine.
Technical scheme:
A kind of respiratory organ, including respiratory organ seat, respirator body, respiratory organ lid, filter screen, exhausting stub tube；By 2 respiratory organ seats, 1 respirator body, 1 respiratory organ lid, 1 filter screen and 1 exhausting stub tube composition；With the vertical profile cross section at exhausting stub tube axis place, symmetrical；4 first bolts 6 and 2 second bolts 11 realize connecting firmly with electromotor；Seal with flat sealant between respiratory organ seat and respirator body, seal with flat sealant between respirator body and respiratory organ lid；Realize connecting firmly by 4 the 3rd bolts 5 between respiratory organ seat, respirator body and respiratory organ lid three；Exhausting stub tube is fastened on respiratory organ by 2 the 4th bolts and covers face；Realize reliably sealing by sealing gasket between respiratory organ seat and engine body.
Respiratory organ seat bottom portion is internal with the crankcase producing gas mixture to be connected, the upper surface of respiratory organ seat connects with the lower surface of respirator body, the upper surface of respirator body be used for make the surge chamber 1 of the adequately expanded respiratory organ lid of gas mixture connect with surge chamber 2, two surge chambers are positioned in symmetric position, connected with filter-core shell and cover plate by passage, remainder above passage is separated with surge chamber 1 and surge chamber 2 by two baffle plates respectively, and filter-core shell connects with the exhausting stub tube being used for discharging waste gas.
For the little oil droplets cool in gas mixture, deposition, filtration, separation filter screen, by filter-core shell and cover plate fixed position, filter screen two spill ports leading to oil sump arranged below.
Beneficial effects of the present invention:
1. ensure that engine oil gas separates more thorough, reduce discharge, reduce consumption of lubricating oil；
2. this respiratory organ structure is simple, rationally distributed, and oil-gas separation efficiency is high, it is possible to reach more than 95%；
3. make the oxidation-stabilized performance that machine oil maintenance is good, extend the useful life of machine oil；
4. keep the pressure in crankcase basically identical with external atmosphere pressure, thus reducing lubricating oil leakage and promoting the performance of electromotor.

Detailed description of the invention
A kind of respiratory organ, including respiratory organ seat, respirator body, respiratory organ lid, filter screen, exhausting stub tube；By 2 respiratory organ seats, 1 respirator body, 1 respiratory organ lid, 1 filter screen and 1 exhausting stub tube composition；With the vertical profile cross section at exhausting stub tube axis place, symmetrical；4 first bolts 6 and 2 second bolts 11 realize connecting firmly with electromotor；Seal with flat sealant between respiratory organ seat and respirator body, seal with flat sealant between respirator body and respiratory organ lid；Realize connecting firmly by 4 the 3rd bolts 5 between respiratory organ seat, respirator body and respiratory organ lid three；Exhausting stub tube is fastened on respiratory organ by 2 the 4th bolts and covers face；Realize reliably sealing by sealing gasket between respiratory organ seat and engine body.
Respiratory organ seat bottom portion connects with the inside of the crankcase producing gas mixture, the upper surface of respiratory organ seat connects with the lower surface of respirator body, the upper surface of respirator body be used for make the surge chamber 1 of the adequately expanded respiratory organ lid of gas mixture connect with surge chamber 2, two surge chambers are positioned in symmetric position, connected with filter-core shell and cover plate by passage, remainder above passage is separated by baffle plate and surge chamber 1, being separated by baffle plate and surge chamber 2, filter-core shell connects with the exhausting stub tube being used for discharging waste gas.
For the little oil droplets cool in gas mixture, deposition, filtration, separation filter screen, by filter-core shell and cover plate fixed position, the filter screen spill port leading to oil sump arranged below.
Specific works process is:
The gas mixture produced in crankcase is first via the upper surface of respiratory organ seat, it is then passed through lower surface and the upper surface of respirator body, finally enter surge chamber 1 and the surge chamber 2 of respiratory organ lid, gas mixture is after fully expanding, after two baffle plates, by passage through filter-core shell and cover plate, waste gas is finally discharged by exhausting stub tube.Little oil droplet in gas mixture, through condensation, deposition, filters, after separation, flows back to oil sump after spill port.
The fixing of filter screen is realized by filter-core shell and cover plate.The effect of filter screen is that the dust outside stoping enters crankcase, the little oil droplet of low concentration in oil gas can also be filtered again simultaneously, separation when crankcase inside is for negative pressure.Little oil droplet finally flows back to oil sump through two spill ports.
Gas mixture passes through 4 grades of separation.Above 3 grades mainly carry out mechanical collision and gravitational settling in respiratory organ, then again by remaining low concentration gas mixture through the 4th grade of separation, sedimentation, oil-gas separation efficiency can reach more than 95%.
