Description
Technical field
The utility model relates to a kind of centrifugal oil strainer, belongs to engine fittings.
Background technique
Centrifugal oil strainer, for removing the impurity such as particle, coal particles after dust in machine oil, carbon precipitates, galling, ensures that diesel engine is to the usage requirement of machine oil.The centrifugal oil strainer of present diesel engine, its structure is substantially identical, comprises base, housing, rotor shaft, rotor body and nozzle.Rotor body drives machine oil to rotate, and the large granular impurity in machine oil or the larger mechanical admixture of density can get rid of under the influence of centrifugal force on rotor body inwall.This metre filter precision is low, cannot remove small solid particle polluter.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of centrifugal oil strainer, greatly can improve the filter precision of machine oil.
Centrifugal oil strainer described in the utility model, comprise base, housing, rotor shaft, central shaft, rotor body, nozzle, rotor shaft is hollow shaft, gap is there is between rotor shaft and central shaft, the lower end of rotor body is provided with the nozzle of two symmetries, the arranged outside of rotor shaft to have in a cylindrical shape air guide sleeve under air guide sleeve and a cylindrical shape, forms oil suction chamber, form refluxing chamber between rotor shaft and lower air guide sleeve between rotor shaft and upper air guide sleeve.
In utilization, the filtration of the effect of air guide sleeve solid-liquid separation and lower air guide sleeve, substantially increases the filter precision of machine oil.
Described upper air guide sleeve is positioned at the top of lower air guide sleeve, there is a flanging upper end of upper air guide sleeve, and this flanging and rotor body inwall have a gap, and there is an in-flanges lower end of upper air guide sleeve, this in-flanges is connected with rotor shaft, this in-flanges by oil suction chamber and refluxing chamber spaced apart.
Described lower air guide sleeve upper end is connected with the lower end of upper air guide sleeve, and the lower end of lower air guide sleeve is connected with rotor body.
Have an oil duct in described central shaft, this oil duct communicates with the gap between central shaft and rotor shaft.
One oilhole is arranged at the top of described rotor shaft, and this oilhole communicates with oil suction chamber.
Working principle:
Machine oil containing impurity flows out from the gap before upper air guide sleeve and rotor inner wall, solid in machine oil is separated to rotor body inwall, clean machine oil enters into spray in rotor body and by two nozzles and forms a pair reaction balance thrust, rotor body starts to rotate around central shaft, machine oil containing impurity impurity in the cavity of High Rotation Speed is all separated to rotor body inwall, clean machine oil after lower air guide sleeve filters sprays from nozzle, flows into oil sump through oil outlet.
Compared with prior art, the beneficial effect that the utility model has is:
The arranged outside of the utility model rotor shaft has had the lower air guide sleeve of solid-liquid separation work air guide sleeve and filtration, substantially increases filter precision.
Accompanying drawing explanation
Fig. 1, whole-cutaway view of the present utility model.
In figure: 1, base; 2, housing; 3, lower air guide sleeve; 4, rotor shaft; 5, central shaft; Air guide sleeve on 6; 7, rotor body; 8, changing valve; 9, oil outlet; 10, filler opening; 11, nozzle.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, centrifugal oil strainer described in the utility model, comprise base 1, housing 2, rotor shaft 4, central shaft 5, rotor body 7, nozzle 11, rotor shaft 4 is hollow shafts, be enclosed within the outside of central shaft 5, central shaft 5 is arranged on base 1, and the below of base 1 is provided with filler opening 10 and oil outlet 9, also be provided with a changing valve 8 in base 1, housing 2 is arranged on the outermost of whole filter.The nozzle 11 of two symmetries is positioned at the lower end of rotor body 7, and rotor body 7 covers on the outside of central shaft 5 and rotor shaft 4, and the arranged outside of rotor shaft 4 has air guide sleeve 3 under a cylindrical shape, there is space between rotor shaft 4 and lower air guide sleeve 3.
The outside of rotor shaft 4, the top of lower air guide sleeve 3 are provided with air guide sleeve 6 in a cylindrical shape; Space is there is between upper air guide sleeve 6 and rotor shaft 4; The upper end of upper air guide sleeve 6 has one to turn up chamfering, and the inner side of itself and rotor body 7 is adjacent and have a gap; There is a varus chamfering lower end of upper air guide sleeve 6, and it contacts with rotor shaft 4.The upper end of lower air guide sleeve 3 contacts with the lower end of upper air guide sleeve 6, and the lower end of lower air guide sleeve 3 contacts with the lower end of upper air guide sleeve 6.Have an inner passage in central shaft 5, there is a hole upper end.
Working procedure:
Starter oil pump, when pressure rises to 0.25MPa, changing valve 8 is opened, machine oil containing impurity enters from filler opening 10, enter in rotor shaft 4 by central shaft 5 internal galleries, then flow out in the hole of rotor shaft 4 upper end, under the effect of upper air guide sleeve 6 containing the machine oil of impurity enter into by air guide sleeve 6, in the cavity that lower air guide sleeve 3 and rotor body 7 are formed, along with the continuous injection of machine oil, when being full of cavity, oil pressure sharply raises, clean machine oil after lower air guide sleeve 3 filters enters in rotor body 7, nozzle 11 finally by rotor body 7 lower end two symmetry sprays, form a pair reaction balance thrust, rotor body 7 starts to carry out slow circumvolve around central shaft 5.Along with jack body 7 rotating speed of pressure improves constantly, the impurity in the cavity of High Rotation Speed of the machine oil containing impurity is all separated to rotor body 7 inwall, and the clean machine oil after lower air guide sleeve 3 filters sprays from nozzle 11, flows into oil sump through oil outlet 9.
