Description
Technical field
The present invention relates to the device that a kind of lubricating oil refluxes, relate in particular to the device that a kind of annular isolation formula resuscitation apparatus lubricating oil refluxes, belong to Marine Diesels field.
Background technique
When motor normally moves, the gas pressure in crankcase can constantly raise, fluctuation, conventionally utilizes resuscitation apparatus to slow down, reduce the pressure in crankcase.In resuscitation apparatus, operated by rotary motion has gas and oil separating plant, is used for filtering crankcase and discharges the most of lubricating oil in air-flow, and the lubricating oil after filtration is back to crankcase, thereby reduces lubricating oil oil consumption.
The general employing of the motor resuscitation apparatus open in usual of marine diesel engine, allows the lubricating oil after separating directly flow back into crankcase.But because the relative resuscitation apparatus of crankcase outlet port exists pressure difference, the lubricator of crankcase inside fails to be convened for lack of a quorum and continues to enter resuscitation apparatus suction tude, if the oil pathway that resuscitation apparatus refluxes is in air-flow path, the follow-up air-flow entering can blow lubricating oil to resuscitation apparatus again, the effect that resuscitation apparatus separates lubricating oil be can reduce like this, lubricating oil discharge and oil consumption increased.
Summary of the invention
Because the above-mentioned defect of prior art, technical problem to be solved by this invention is to provide one drainback passage is separated with air-flow path, and reduces the reflux of reverse pressure reduction on lubricating oil backflow impact.
For achieving the above object, the invention provides the device that a kind of annular isolation formula resuscitation apparatus lubricating oil refluxes, its structure comprises Oil-gas Separation parts, lubricating oil recovery part, the gentle stream guide element of lubricating oil backflow parts; Wherein, described Oil-gas Separation parts are arranged on the air outlet place at resuscitation apparatus top, described gas channeling parts are communicated with the suction port that is arranged on described resuscitation apparatus bottom, described lubricating oil recovery part is arranged on described resuscitation apparatus bottom and is looped around around described gas channeling parts, and described lubricating oil backflow parts are communicated with described lubricating oil recovery part.
Further, described gas channeling parts are cylindricality.
Further, the opening of described gas channeling parts one end is greater than the opening of the other end, and one end that opening is larger is communicated with described suction port.
Further, one end of described gas channeling parts is communicated with described suction port, and the other end opening is towards described Oil-gas Separation parts.
Further, described lubricating oil backflow parts in a tubular form.
Further, described lubricating oil backflow parts have first end and the second end, described first end is arranged on described lubricating oil recovery part bottom and is communicated with described lubricating oil recovery part, and described the second end is arranged on crankcase inside, and described first end is vertically higher than described the second end.
Further, described lubricating oil backflow parts also have lowest part, and lowest part is between described first end and described the second end described in along continuous straight runs, and vertically described lowest part is lower than the height of described first end and described the second end.
Further, described lubricating oil backflow parts are provided with multiple.
Further, described lubricating oil recovery part is spill.
Further, the described lubricating oil backflow parts tubulose that takes the shape of the letter U.
The working procedure of the device that annular isolation formula resuscitation apparatus lubricating oil of the present invention refluxes is: the mist of oil containing lubricating oil of crankcase inside is blown into described gas channeling parts from the suction port of resuscitation apparatus, and flow in described gas channeling parts, until from described gas channeling parts out, then pass through the effect of described Oil-gas Separation parts, lubricating oil in mist of oil is separated from mist of oil, and flow into described lubricating oil recovery part along resuscitation apparatus madial wall, a part of mist of oil after separation flows into atmosphere environment from air outlet, another part is condensed into lubricating oil and flows into described lubricating oil recovery part along resuscitation apparatus madial wall.Lubricating oil in described lubricating oil recovery part can not flow directly into crankcase, but first flow into described lubricating oil backflow parts, in the time that the lubricating oil in described lubricating oil backflow parts reaches a certain amount of, the lubricating oil pressure of the described first end opening of described lubricating oil backflow parts can be offset the air pressure in crankcase completely, thereby the lubricating oil in described lubricating oil backflow parts flows into crankcase smoothly from described the second end.
Beneficial effect of the present invention is:
1, be provided with gas channeling parts at the suction port of resuscitation apparatus, directly near of the mist of oil guiding Oil-gas Separation parts with lubricating oil of resuscitation apparatus will be entered, being beneficial to lubricating oil separates with the rapid of mist of oil, simultaneously by mist of oil with lubricating oil with separate after lubricating oil separate, that has reduced that lubricating oil after separating flows into crankcase from suction port may.
2, lubricating oil recovery part is set to be looped around air-flow guide element around, can collect more fully the lubricating oil after separation, has improved the recovery rate of lubricating oil.
3, in resuscitation apparatus bottom, the lubricating oil backflow parts that are communicated with lubricating oil recovery part are set, and its two ends height difference, the lubricating oil refluxing like this enters after lubricating oil backflow parts because the two ends different mineralization pressures of sliding level height are poor, this pressure difference can be offset the reverse pressure difference existing between crankcase and suction port, thereby ensure that the lubricating oil in lubricating oil backflow parts relies on self gravitation to flow freely into crankcase completely, effectively ensure that in resuscitation apparatus, the lubricating oil after separation is back to crankcase smoothly, improve the utilization ratio of lubricating oil, thereby reduced the lubricating oil oil consumption of motor.
Below with reference to accompanying drawing, the technique effect of design of the present invention, concrete structure and generation is described further, to understand fully object of the present invention, feature and effect.
Brief description of the drawings
Fig. 1 is the schematic diagram of the device of the annular isolation formula resuscitation apparatus lubricating oil backflow of a preferred embodiment of the present invention;
Fig. 2 is the schematic diagram of the device of the annular isolation formula resuscitation apparatus lubricating oil backflow of another preferred embodiment of the present invention.
