Abstract

The utility model discloses a core replacing type engine oil filter, comprising a housing and a filter element. The top inside the housing fixes a spring, and the top cover of filter element presses against the bottom of the spring. A feeding mid level outlet covers outside a process ora on a feeding nut and is sealed passing a sealing ring. The lower cover of the housing spiral joints with the housing, and is sealed passing a sealing cushion. The oil inlet of the lower cover of the housing interconnects with a thread hole of the feeding nut, and an oil outlet is installed outside the circumference corresponding with the feeding nut. The sealing ring is installed around the oil outlet of the lower cover of the housing, and a feeding screw put the lower cover of the housing to spiral joint with the body. The utility model is simple in structure, cheep in fabrication cost, convenient in disassembly, installation, renewing filter element. Accordingly, so long as changing the filter element regularly, scientifically and reasonably, the engines can guaranteed to lubricate and cool components normally. The utility model takes the insurance effect to the failure-free operation of the engines, accordingly it avoids the personnel and economic great damage caused by the locomotive failure caused by the bad engine oil filtering and the unnecessary traffic accidents.

Description

The replaceable filter element type oil filter

Technical field

The utility model relates to a kind of replaceable filter element type oil filter.

Background technique

At present, oil filter dismounting, cleaning inconvenience, therefore, filter core often takes place and stops up and to cause that oil lubricating and critical component heat radiation are bad and introduce phenomenons such as axis tile, sticking cylinder in locomotive, at road vehicle more or when running at high speed if this type of accident of generation also can cause car crash.

Summary of the invention

Its purpose of the utility model is: a kind of replaceable filter element type oil filter is provided, and it is simple in structure, and is easily manufactured, cheap, and its installation, convenient disassembly can regularly replace filter core according to use condition, thereby brings the sense of security for locomotive driving.

The utility model is achieved in that a kind of replaceable filter element type oil filter, comprise: housing and filter core, the affixed spring of described housing inner top, its filter core loam cake pressing spring bottom, its oil-feed mesopore is enclosed within on the oil-feed nut outside the breach, and by the seal ring sealing, its housing lower cover and housing are spirally connected, and seal by sealing gasket; Described housing lower cover oil inlet hole is communicated with the tapped hole of oil-feed nut, the outer oil outlet that is provided with of its periphery corresponding with the oil-feed nut; The oil outlet periphery of its housing lower cover is provided with seal ring, and the oil-feed screw is bolted in the housing lower cover on the body.

Described filter core is by the filter core loam cake and go to the bottom and inside and outside filter core constitutes, and establishes in the middle of the described inside and outside filter core in the middle of the space is fixed in the filter core loam cake and goes to the bottom, and its inner filter core is the sieve aperture tubular, its upper and lower and the filter core loam cake and the affixed one of going to the bottom; Described outer filter core is the stacker filter core, is located at outside the inner filter core, is installed within filter core loam cake and the edge of going to the bottom.

The oil outlet periphery of described housing lower cover is provided with groove, and seal ring is arranged between housing and the groove, establishes prominent ring between its oil outlet and the oil inlet hole.

Tops is provided with groove on the described filter core, and spring is arranged between housing and the groove.

Described case top is a sphere shape, establishes groove in the middle of its outward appearance.

The utility model is simple in structure, installation, convenient disassembly, the user can be according to the locomotive use condition, the periodic replacement filter core, make the normally lubricated and crucial parts cooling of locomotive, guarantee locomotive safety running, avoid, thereby avoided the lubricated and bad traffic accident that locomotive failure causes that occurs of dispelling the heat because of locomotive because of the not good generation that causes locomotive failure of oil filtration.

Embodiment

Embodiment 1:

Its structure is shown in Fig. 1-4: a kind of replaceable filter element type oil filter, comprise: housing 1 and filter core, the affixed spring 9 of described housing 1 inner top, its filter core loam cake 2 pressing springs 9 bottoms, its oil-feed mesopore 204 is enclosed within on the oil-feed nut 8 outside the breach, and by the seal ring sealing, its housing lower cover 6 is spirally connected with housing, and seals by sealing gasket; Described housing lower cover oil inlet hole 602 is communicated with the tapped hole of oil-feed nut 8, the outer oil outlet 601 that is provided with of its periphery corresponding with the oil-feed nut; The oil outlet periphery of its housing lower cover 6 is provided with seal ring 7, and the oil-feed screw is bolted in the housing lower cover on the body.

Described filter core by filter core loam cake 2 and go to the bottom 205 and inside and outside filter core 203,201 constitute, establishing the space in the middle of the described inside and outside filter core 203,201 is fixed in the filter core loam cake and goes to the bottom middle, its inner filter core 203 is the sieve aperture tubular, its upper and lower and the filter core loam cake 2 and the 205 affixed one of going to the bottom; Described outer filter core 201 is the stacker filter core, is located at outside the inner filter core, is installed within filter core loam cake and the edge of going to the bottom.

Oil outlet 601 peripheries of described housing lower cover 6 are provided with groove 5, and seal ring 7 is arranged between housing and the groove 5, establish prominent ring 603 between its oil outlet 601 and the oil inlet hole 602.

Described filter core loam cake 2 tops are provided with groove 202, and spring 9 is arranged between housing 1 and the groove 202.

Described housing 1, housing lower cover 6 adopt the metallic material press forming; The filter core loam cake of described filter core, go to the bottom, and inner filter core adopts the metallic material sheet stamping to form.

Described seal ring, sealing gasket adopt rubber material.

Renew cartridge process more:

As long as housing 1 is screwed off, its filter core can conveniently be pulled down; Change new filter core, as long as it is housing 1 is screwed on housing lower cover 6 again, very simple and feasible.

Working procedure:
