Furthermore, the oil filter main body is provided with a plurality of liquid leakage holes which are uniformly distributed on the oil filter main body.
Preferably, the upper cover plate and the lower cover plate are fixedly connected through stud bolts.
Further, stud is equipped with 3 at least, and the equipartition in the upper cover plate with on the apron down.
Specifically, the upper cover body is provided with an upper sealing groove matched with the upper end edge of the oil filter main body; the lower cover body is provided with a lower sealing groove matched with the edge of the lower end of the oil filter main body.
Preferably, the oil filter body has a cylindrical structure.
Compared with the prior art, the utility model discloses following beneficial effect has:
(1) the utility model discloses ingenious sets the oil filter main part to and comprises the material of strong magnetism, at drilling pump drive mechanism lubricating oil, when entering into the oil filter, the produced iron fillings of mechanical wear adsorb in the drilling pump drive mechanism in the oil filter main part through the oil filter main part of strong magnet, effectual filtration to the produced iron fillings of mechanical wear in the drilling pump drive mechanism, the effectual secondary damage of having avoided iron fillings to drilling pump drive mechanism has improved the holistic life of drilling pump.
(2) The utility model discloses an upper cover plate and lower cover plate pass through stud's form, fix the terminal surface edge at both ends about the oil filter, can not only effectively realize the lid and the sealed of lid and oil filter main part down, also can lift the lid simultaneously off with lower lid through the form of dismantling stud simultaneously, very big having made things convenient for the washing in the oil filter main part, also made things convenient for the change to filter screen in the oil filter main part, promoted the convenient degree of washing of oil filter greatly.
(3) The utility model discloses a set up upper seal recess and lower seal recess on upper cover plate and lower cover plate respectively, outside the sealed effect at upper cover plate and lower cover plate and oil filter main part both ends edge has been improved, still effectual realized between upper cover plate and the lower cover plate and between the oil filter main part spacing, very big installation that has made things convenient for upper cover plate and lower cover plate is counterpointed, has promoted the dismantlement installation effectiveness of upper cover plate and lower cover plate.
