Abstract

The utility model provides a filtering core which is especially suitable for the fuel filter of an electronic jetting internal combustion engine. The utility model is formed by that a column core tube which is made of super molecule polyethylene and is seamless integrally and an upper end cover and a lower end cover are glued. The filtering effect of the filtering core is enhanced. The utility model has the advantages of vibration resistance, no deformation and corrosion resistance; the fuel-jetting and atomizing effect can be enhanced.

Description

The electrospray filter element

The utility model relates to a kind of filtrating equipment of fuel oil, especially is specially adapted to the filter core of the fuel filter of electrospray formula internal-combustion engine.

At present, the filter core that is used for the fuel filter of internal-combustion engines such as automobile, all adopt folded filter paper to enclose and connect the core pipe of making, with last, the lower end cap bonding forms, and at core inner tube wall lining with the wire netting skeleton as supporting, on, lower end cap is fixed on the iron pipe of center, and an end of iron pipe has binding thread, and it uses shortcoming very big, because filter paper system filter core sticks with glue knot at the radial tab place, two end part and last, lower end cap is also by glue bond, and is easy to crack after soaked with liquid, and filter paper needs to handle through impregnated phenolic resin, stopped up the part hole, after the soaked with liquid, paper volumetric expansion distortion changes aperture, influences filtering effect, be subjected to extraneous pressure, paper filter element is yielding, and effective filtration area dwindles, wire netting skeleton easy-to-rust.And it is serious that the process environmental pollution is manufactured in the production of filter paper.

The purpose of this utility model is will provide a kind of can overcome the shortcoming that the said goods exists effectively, improves the novel fuel filter element of fuel oil filter quality.

The utility model is achieved through the following technical solutions.The filter core of fuel filter is made up of upper end cap, lower end cap, core pipe, and the core pipe is the column tube of the integral seamless made by ultra high molecular polyethylene, and its wall cross-section is ripple Qu Huizhuan, to increase tube wall area.

The filter element of the utility model has the following advantages:

1, the polyvinyl plastic core pipe has higher antidetonation, resistance to compression, decay resistance, and integral seamless does not firmly ftracture with end cap is bonding, has improved working life widely.

2, because this core tube wall filtering hole is reliable through being evenly distributed, and effective filtration area increases, and the filtering effect improves, the oil atomizing effect is improved, free from environmental pollution, and improve oil pump oil greatly and chew working life.

3, engine fuel consumption is reduced greatly, because good filtration effect has reduced the wearing and tearing of engine fittings.

Below in conjunction with accompanying drawing the utility model structure is described in further detail.

Fig. 1 is the longitudinal sectional view of the utility model filter core.

Fig. 2 is along A-A line sectional view among Fig. 1.

Form by upper end cap (1), lower end cap (3), core pipe (2) with reference to Fig. 1, Fig. 2, the utility model filter core, core pipe (2) is the column tube of the integral seamless made by ultra high molecular polyethylene, its wall cross-section is ripple Qu Huizhuan, and upper end cap (1), lower end cap (3) bond respectively at the two ends of core pipe (2).

Claims

1, a kind of electrospray filter element is made up of upper end cap, lower end cap, core pipe, it is characterized in that core pipe (2) is the column tube of the integral seamless made by ultra high molecular polyethylene, and its wall cross-section is the ripple allusion quotation and returns shape.
