Description
Technical field
The utility model relates to a kind of crankcase bleeder.
Background technique
In, on the low-speed diesel engine, gather too much and avoid the temperature and pressure in crankcase too to increase in order to prevent in the crankcase oil gas, crankcase generally also will be provided with gas permeable devices except that explosion-proof valve is installed.
General gas permeable devices is that the purpose that baffle plate reaches separation oil and gas is set in path, baffle plate spills and oil droplet is kept off back in the crankcase in order to prevent machine oil, oil gas is discharged along path, but this structure can only play the purpose of collecting most of machine oil in the oil gas, small amount of engine oil still can be discharged with oil gas, cause unnecessary consumption of lubricating oil, and oil gas can pollute to air; And traditional gas permeable devices that filter formula filtering type deaerator is housed causes the manufacturing difficulty because of complex structure, use, maintaining inconvenience, and the too close crankcase of the filter that has, machine oil splashes the filter surface easily, causes the machine oil alluvial and the obstruction gas permeable devices.
Therefore need a kind of crank case ventilation installation, satisfy the machine oil in the abundant separation oil and gas of energy, to save machine oil and to prevent also have characteristics simple in structure, easy to maintenance simultaneously by the oil vapour pollution air.
The model utility content
In view of this, the purpose of this utility model provides a kind of crankcase breather, and it is the machine oil in the separation oil and gas fully, reduces the machine oil waste, prevents the oil vapour pollution air, and it also has simple in structurely, and working service is characteristics easily.
The utility model crankcase breather comprises the ventilator housing that crankcase intracavity is communicated with atmosphere and is arranged at the filtering type deaerator that is used for the gas that enters atmosphere from crankcase is carried out Oil-gas Separation in the ventilator housing.
Further, described ventilator housing comprises air guide bend pipe and the bend pipe end cap that is communicated with and is bent upwards with crankcase, described filtering type deaerator be positioned at air guide bend pipe on the section of stretching, and filtering type deaerator position is higher than crankshaft axis;
Further, described filtering type deaerator is for being made of the tubular filter of tube wall filter layer the fine and close arrangement of wire;
Further, the inside bending of the section of stretching tube wall is formed for supporting the annular flange flange of filtering type deaerator lower end surface on the described air guide bend pipe, and be abutted against with the bend pipe end cap described filtering type deaerator upper end;
Further, the cross section that the section of stretching is positioned at filtering type deaerator below on the described air guide bend pipe is provided with rib, and described bend pipe end cap is provided with the handle with the rib screw-thread fit, and described bend pipe end cap is pressed on the air guide bend pipe upper-end surface by handle;
Further, described air guide bend pipe is connected with crankcase and is provided with seal washer between end face;
Further, described air guide bend pipe is positioned on the tube wall of filtering type deaerator exhaust side and is provided with a relief opening at least.
The beneficial effects of the utility model: the utility model crankcase breather, adopt the filtering type deaerator that oil gas is separated, good oil gas separation effect can reduce the machine oil waste greatly and avoid the oil vapour pollution air; This apparatus structure is simple simultaneously, opening the bend pipe end cap can take out the filtering type deaerator, it is carried out clean and maintenance work, safeguard simple and convenient, also can add machine oil to crankcase simultaneously by the resuscitation apparatus bend pipe, crankcase does not need to establish in addition machine oil again and adds mouth, can simplify crankcase structure, makes maintaining work more convenient.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment
Accompanying drawing is the utility model crankcase breather symmetrical section sectional view longitudinally.
As shown in the figure, the utility model crankcase breather comprises the ventilator housing that crankcase intracavity is communicated with atmosphere and is arranged at the filtering type deaerator 1 that is used for the gas that enters atmosphere from crankcase is carried out Oil-gas Separation in the ventilator housing.By the filtering type deaerator oil gas is separated, the machine oil that is separated flows back to crankcase by ventilator housing, and this crankcase breather good oil gas separation effect can reduce the machine oil loss greatly, avoids oil gas that air is polluted.
In the present embodiment: described ventilator housing comprises air guide bend pipe 2 and the bend pipe end cap 3 that is communicated with and is bent upwards with crankcase, described filtering type deaerator 1 be positioned at air guide bend pipe 2 on the section of stretching, and filtering type deaerator 1 position is higher than crankshaft axis.Filtering type deaerator 1 is higher than the machine oil that throws away when crankshaft axis can avoid bent axle to rotate and is bonded on the filtering type deaerator 1, can avoid machine oil too much to stop up the filtering type deaerator.
In the present embodiment: described filtering type deaerator 1 is for by the fine and close tubular filter that constitutes the tube wall filter layer of arranging of wire, and is simple in structure, easily manufactured.
In the present embodiment: the inside bending of the section of stretching tube wall is formed for supporting the annular flange flange 2a of filtering type deaerator 1 lower end surface on the described air guide bend pipe 2, and described filtering type deaerator 1 upper end and bend pipe end cap 3 are abutted against.Oil gas enters filtering type deaerator 1 interior conduit, and discharges through filtering type deaerator 1 tube wall, and oil gas and filtering type deaerator 1 area of contact are big, and separating rate is fast.
In the present embodiment: the cross section that the section of stretching is positioned at filtering type deaerator 1 below on the described air guide bend pipe 2 is provided with rib 2b, described bend pipe end cap 3 is provided with the handle 4 with rib 2b screw-thread fit, and described bend pipe end cap 3 is pressed on the air guide bend pipe upper-end surface by handle 4.Screwing off handle can take out bend pipe end cap 3 and filtering type deaerator 1, can be to easily the filtering type deaerator being safeguarded, also can add machine oil to crankcase by bend pipe simultaneously, machine oil adds simple and convenient, makes crankcase needn't establish oil filler more in addition.
