Universal rotary type oil product filter cleaner provided with differential pressure alarm and replaceable filter element

Abstract

The invention discloses a universal rotary type oil product filter cleaner provided with a differential pressure alarm and a replaceable filter element. The universal rotary type oil product filter cleaner comprises a casing and the filter element arranged in the casing, wherein a threaded connecting plate is arranged between an opening of the casing and an oil outlet of the filter element, and a butting threaded through hole is formed in the center of the threaded connecting plate and communicated with an oil outlet channel of a filter base of the filter cleaner; a plurality of oil inlet through holes are formed in the threaded connecting plate and communicated with an oil inlet channel in the filter base of the filter cleaner; the differential pressure alarm is arranged on the filter base; a plurality of symmetrically distributed convex teeth are arranged on an outer ring of the threaded connecting plate, grooves matched with the convex teeth are formed in the opening of the casing, and the threaded connecting plate is pressed and attached to the oil outlet of the filter element under the action of an elastic support piece at the bottom of the casing. According to the universal rotary type oil product filter cleaner provided with the differential pressure alarm and the replaceable filter element, the problems that the filter element in the casing of a conventional filter cleaner is non-replaceable and interchangeability of the filter cleaners produced by different manufacturers is poor are solved, the replacement is simple, the operation is easy, and the overpressure protection on the casing is easy to realize.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to an oil filter, in particular to a replaceable filter core and a filter housing assembly with a reusable housing. Background technique [0002] Existing commercially available diesel oil filter, it mainly has two kinds of forms, and a kind of is integral spin-on type, and a kind of is detachable replacement filter element type. [0003] The housing of the integral spin-on filter is provided with an oil inlet and an oil outlet, and communicates with an external oil inlet passage and an oil outlet passage through a filter seat. The filter element is set in the casing, and the casing and the filter element are integrated and cannot be disassembled separately. After the service life of the filter element expires, the filter element and the housing must be replaced as a whole, and the replaced filter housing can only be discarded. The advantage is that the filter seat and the shell are connect...
