DEVICE FOR STRAINER FILTERING INCLUDING FILTERING TUBE

摘要

PROBLEM TO BE SOLVED: To provide a device for strainer filtering including a filtering tube, which has a substantially larger filtering area for the same length and width, can substantially reduce foreign matters that cover an induction surface and flow-through resistance from the foreign matters, and which accordingly reduce the decrease in the pressure of a coolant before and after flowing through.

SOLUTION: The device for strainer filtering including the filtering tube has at least one inlet side for receiving the coolant and a discharge side for discharging the filtered coolant. The device includes: the filtering tube comprising a hollow tube which is formed by bending a punched plate having a plurality of filtering holes; an upper portion plate having a first groove formed on the lower surface thereof so as to couple the upper end of the filtering tube, and having an inlet portion for receiving the coolant; and a lower portion plate having a drilled hole to which the lower end of the filtering tube is coupled. The filtered coolant inside the filtering tube flows into the drilled hole and is discharged from the discharge side.
