Description
Technical Field
The invention relates to a diesel engine respirator, in particular to a breathing device of a totally-enclosed lifeboat diesel engine crankcase, belonging to the technical field of diesel engine safety and environmental protection.
Background
During the working process of the diesel engine, the side gap between the piston and the cylinder body leaks air, the moving part stirs lubricating oil, gas generated by high-temperature evaporation of the lubricating oil and the like is accumulated, the pressure in the crankcase is higher and higher, and if the gas cannot be discharged in time, the explosion of the crankcase can be even caused under extreme conditions, so that the crankcase of the diesel engine must have a breathing function outwards, and the internal air pressure of the crankcase of the diesel engine and the external atmospheric pressure are kept balanced.
At present, the breathing apparatus of the crankcase of the diesel engine is divided into two types according to the discharge mode, one type is to directly discharge the gas in the crankcase of the diesel engine into the atmosphere, such as: patent numbers: 201720717497.8, name: respirator and diesel engine of diesel engine, this respirator is with the crankcase in gaseous, filter filler 70 (being the steel wire filter screen) that the filter orifice set up of giving vent to anger filters the back, directly the atmosphere of discharging into, because the filter orifice volume of giving vent to anger of respirator is less, and set up by the machine, need bear the other heat radiation of machine of diesel engine, therefore, this respirator gives vent to anger the filter orifice radiating effect relatively poor, oil gas passes through the steel wire filter screen for a long time in addition, make the temperature of steel wire filter screen constantly rise, and the oil gas temperature in the crankcase of continuous access, that is to say, the air current is when passing through the steel wire filter screen, its kinetic energy loss is very little, thereby lead to the oil congealing effect of steel wire filter screen poor, most machine oil still discharges into the atmosphere with the gaseous together in the oil gas, not only make the machine oil loss of diesel engine great, and the polluted environment still.
The other respirator is that gas in a crankcase of the diesel engine is condensed by an air inlet labyrinth and then is discharged into an air inlet pipe of the diesel engine through a pipeline, and oil gas enters a combustion chamber from the air inlet pipe to be combusted and then is discharged into the atmosphere; such as patent numbers: 201410128214.7, name: a 360-degree overturn lifeboat diesel engine auxiliary respirator; the air inlet of the breather is arranged in the gear chamber, and a labyrinth is arranged at the air inlet, so that the engine oil in the oil gas is separated out through the labyrinth; in fact, the condensed oil pollution reduction effect is not good, because the air inlet labyrinth is arranged in the gear chamber of the diesel engine and communicated with the crankcase, the oil gas temperature in the labyrinth is the same as the oil gas temperature in the crankcase; in the same high-temperature environment, the kinetic energy loss of oil gas passing through the labyrinth is small, so that the condensed oil drop effect of the labyrinth is poor; in addition, the grids in the labyrinth are arranged up and down, and oil return holes (422A) are formed in the bottom of the lower grid for oil return; if the oil return hole (422A) is too small, oil return is not smooth, and the lower grid can be filled with engine oil and the air passage is blocked as time goes on due to condensed oil and splashed engine oil in the gear chamber, so that the respirator is out of work; if the oil return hole (422A) is too large, because the oil gas passes through the oil return hole (422A) and is smaller than the resistance of passing through the labyrinth, the oil gas part in the crankcase can not pass through the labyrinth and is directly discharged from the oil return hole (422A), so that the labyrinth oil condensation effect is further deteriorated, high-temperature oil gas enters the air inlet pipe through a pipeline, and because the molecular kinetic energy of high-temperature gas is large, the gas expands, so that the mole number of oxygen molecules in the unit volume of the air inlet pipe is reduced compared with that of the air at normal temperature, and the air inlet oxygen content of a diesel engine cylinder is influenced; however, under the standard air pressure and temperature of the diesel engine, the air inflow of the cylinder and the oil supply of the combustion chamber are optimally matched, if the oxygen content of the air in the cylinder is reduced and the engine oil in the oil gas is increased, the combustion of the mixture of the diesel oil and the engine oil in the combustion chamber of the diesel engine is insufficient, so that the emission of the diesel engine is influenced, the pollution to the environment is increased, and the engine oil consumption of the diesel engine is increased.
In conclusion, in the existing diesel engine breather, in the process of exhausting oil gas from a crankcase, the engine oil in the oil gas cannot be effectively separated, the engine oil consumption of the diesel engine is reduced, and the pollution of the diesel engine to the environment is overcome.

In order to realize that the cooling water of the water channel in the body swings left and right and flows upwards, namely flows upwards from the water channel holes of the left grid plate and the right grid plate in series alternately, the condensation effect on oil gas is improved, and the problem of communication between two adjacent water channels of the body up and down needs to be solved, the invention separates the left end cover and the right end cover from the body through the left and the right separation plates and the water channel holes at the corresponding positions of the water channels, and simultaneously separates the gas outlet channel and the water channel; a closed air passage is formed in the body, oil gas enters the body from the air inlet oil return hole, penetrates through a gap between the front grid plate and the rear grid plate in the body, and then flows out from the air outlet. The water passage hole on the left and right separation plates is communicated between different communicating cavities on the left and right end covers, so that the upper and lower adjacent water passages of the body are connected in series, namely: the water flow is from the water inlet, the water inlet cavity, the first water channel, the first communicating cavity, the second water channel, the second communicating cavity, the third water channel, the third communicating cavity, the fourth water channel, the fourth communicating cavity, the fifth water channel, the water outlet cavity and the water outlet. In addition, when rivers were covered the intercommunication chamber through left and right ends and were linked together, utilize the end cover can also dispel the heat to rivers, further improve the condensation effect of body.
