Abstract
The utility model discloses a secondary filter is with whole type spacer plate opens the mistake oilhole of the back smart filter chamber of the preceding smart filter chamber that has the intercommunication secondary filter and secondary filter on the spacer plate, the utility model discloses a holistic spacer plate structure for the secondary filter has kept current whole advantages that the secondary filter had, still has better centrifugal filtration ability under lower rotational speed condition, simultaneously, if adopt the structure that current one side oil feed one side produces oil, then avoid business turn over oil direct, increase centrifugal filtration's efficiency, install and have better centrifugal filtration effect during in the slow -speed of revolution in the engine, the main is the cross oilhole of passageway for opening on the spacer plate that supplies lubricating oil to pass through, not only makes the joint strength of spacer plate improve, still purifies the in -process in the separation and avoids collecing once more of lubricating oil and impurity, has better separation effect to along with the extension of life cycle, the separation effect has relatively poor influence.
Description
Technical field
The utility model relates to a kind of engine accessory parts and motor thereof, particularly a kind of lubrication oil filtration equipment and motor thereof.
Background technique
Centrifugal fine filter be motor for purifying lubricant oil, ensure the visual plant that each friction pair normally runs.Centrifugal fine filter is generally rotated by the rotating drive centrifugal fine filter of bent axle and utilize the centrifugal force cleaning lubricant oil of centrifugal flow guiding parts, and effect is comparatively obvious.Centrifugal fine filter generally comprises housing and is positioned at the centrifugal flow guiding parts of housing, lubricant oil to enter after in housing by centrifugal action along centrifugal flow guiding part mobile, the solid particle that density is large is positioned at the distalmost end of centrifugal diameter, by paracentral be namely clean lubricant oil.
In prior art, in order to still there is good isolation of purified effect when ensureing low speed, adopt overall separated board structure, larger separation centrifugal force is produced when rotating, still there is good centrifugal filtration ability under lower speed conditions, and there is relatively little radial dimension, save installing space, convenient installation, dismounting and cleaning.But, this structure is used for the gap formed between the edge and housing of separating plate by the passage of lubricant oil, and according to the work principle of filter of secondary filter, impurity also can accumulate in edge by the effect of centrifugal force, block up again after making lubricant oil and magazins' layout and converge, continue to be separated in secondary centrifuging (separating plate inner surface), impurity endless gathering is collected, and causes making isolation of purified effect be deteriorated gradually along with the prolongation of life cycle.
Therefore, need to improve the separating component of existing centrifugal fine filter, not only there is when the slow-speed of revolution good centrifugal filtration effect, there is relatively little radial dimension, save installing space, in isolation of purified process, also avoid again collecting of lubricant oil and impurity, there is better separating effect, and along with the prolongation of life cycle, the impact that separating effect is not poor.
