Use above-mentioned design, there is simple in construction, advantage easy for installation.
In the oil filter of above-mentioned electromotor, the lateral wall of described connecting portion is provided with annular groove, is provided with 0 RunddichtringO in described annular groove, and the medial wall of the outer peripheral face of 0 RunddichtringO and described sealing drum offsets.
Under the effect of 0 RunddichtringO, so that forming more structurally sound sealing between sealing drum and connecting portion, so that Magnet to play more preferable protective effect, make the purpose in raising Magnet and this oil filter life-span carry out more stablely.
In the oil filter of above-mentioned electromotor, described sealing drum is cylindrically, rounded sealing gasket it is provided with in this sealing drum, and the medial wall of the sidewall of sealing gasket and sealing drum reclines, described connecting portion and the lower surface of Magnet all upper surfaces with sealing gasket recline, and the interior diapire of the lower surface of sealing gasket and described sealing drum reclines.
Under the cooperation of sealing gasket and 0 RunddichtringO, enter into the path in connecting portion with effectively prolongation machine oil, thus strengthen the difficulty that machine oil contacts with Magnet, thus extend the life-span of Magnet further, then extend the life-span of this oil filter.
Alternatively, in the oil filter of above-mentioned electromotor, if described sealing member is the sealing plate fixing by bolt stem and connecting portion, and sealing plate the lower surface of upper side and connecting portion seal closely against being formed.
In the oil filter of above-mentioned electromotor, on the lateral wall, upper end of described filter cylinder, there is annular convex shoulder, and annular convex shoulder is coaxial with filter cylinder, described annular convex shoulder reclines mutually with the inner roof wall of cover, and annular convex shoulder is fixed with described cover by some screws.
I.e. filter cylinder is detachably fixed with cover by screw, changes, with further reduction, the cost that filter cylinder is brought.
Compared with prior art, the oil filter of this electromotor has the advantage that
When 1, changing filter cylinder, due to filter cylinder be that the mode being threaded connection is detachably fixed with material storage tube and filter cylinder is detachably fixed with cover by screw, to allow the operator to be individually replaced filter cylinder, relative to needing to change by cover in prior art, this is replaced to break up core, impurity groove and strong magnet, is effectively saved and changes the cost that brought of filter cylinder.
, under the cooperation of sealing gasket and 0 RunddichtringO, enter into the path in connecting portion effectively extending machine oil, thus strengthen the difficulty that machine oil contacts with Magnet, thus extend the life-span of Magnet further, then extend the life-span of this oil filter.
