Description

Lubricating oil filter element

Technical Field

The utility model belongs to the field of mechanical hydraulic pressure, and relates to a lubricating oil filter element.

Background

The aviation manufacturing industry has higher requirement on the cleanliness of products, the filtering precision of a corresponding hydraulic filter of manufacturing equipment generally reaches 10-60 um, so that the blockage is more, particularly for aviation repair products, the surface cleanliness is lower, various carbon deposition impurities are more, and the equipment filter is easily blocked during primary cleaning.

The lubricating oil filter element of the existing aviation manufacturing equipment adopts an integrated filter element, and the filtering material cannot be effectively cleaned or cleaned, so that the filter element needs to be integrally replaced. For the filter element with high filtering precision, the blocking frequency is higher in the using process, the replacement amount is larger, and the cost is higher.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the integrated structure of the filter element is changed into a structure combined by a plurality of filter units, so that the filter units can be independently detached, cleaned and replaced, and the use cost is reduced.

The technical scheme is as follows:

a lubricant filter element, comprising: a central oil pipe, a filter disc and a nut;

one end of the central oil pipe is provided with an opening serving as an oil inlet, a circle of the opening is provided with a step, and the other end of the opening is closed by a nut; an oil passing hole is formed in the wall of the central oil pipe between the step and the nut; the filter disc is sleeved on the central oil pipe between the step and the nut in sequence.

The step surface is propped against the first filter disc, and the nut is propped against the last filter disc.

The filter disc includes: the filter comprises a wave-shaped bracket, two filter screens, an outer ring and an inner ring;

the filter screen is arranged on each of two sides of the wave-shaped support, the outer ring fixes the outer circle of the filter screen on the outer circle of the framework, and the inner ring supports the inner circle of the filter screen.

Further comprising: a gasket; and the step surface and the first filter disc, the nut and the last filter disc and the adjacent filter discs are all separated by gaskets.

Further comprising: and the rubber ring is arranged on the inner wall of the opening.

The inner circle of the filter screen has a certain distance to the inner circle of the framework, and the filter disc has a certain compression amount.

Has the advantages that:

the novel filter element is small and exquisite and light, is easy to assemble and does not need extra tools.

And the filter element is installed on the hydraulic system and is simple to operate.

The filter elements are structurally independent from each other, can be detached and cleaned and replaced independently, and the use cost is reduced.

Detailed Description

The utility model designs a specific structure to guide the lubricating oil to permeate from the inside to the outside of the filter element unit so as to complete the filtration. And each filter element unit is pressed and stacked on the central oil pipe through a nut. The external structure is shown in figure 1.

The structure of the filter element is shown in figure 2 and comprises a rubber ring, a central oil pipe, a filter disc, a gasket and a nut. The rubber ring 1 is arranged in a rubber ring groove on the left side of the central oil pipe 2, 12 filter discs 3 and 13 gaskets 4 penetrate the central oil pipe according to the sequence of figure 2, and finally the nut 5 is screwed on the central oil pipe to compress the filter discs.

The arrow direction in fig. 3 shows the flow direction of the lubricating oil, the right side of the filter element is connected with the oil inlet, the lubricating oil flows into the central oil pipe through the rubber ring seal, and the left drawing in fig. 3 shows the lubricating oil. The outer wall of the central tube is provided with an opening, and the other end of the central tube is provided with a blind hole, which is shown in figure 4. Therefore, the lubricating oil flows out from the strip-shaped holes on the outer wall of the central oil pipe under the pressure guidance and then flows into the inner wall of the filter disc. The filter disc consists of a wave-shaped bracket, a filter screen, an inner ring and an outer ring, and is shown in figure 5. After the lubricating oil enters the filter disc, the lubricating oil is driven by pressure to seep out of the filter screen, and impurities are filtered by the filter screen inside the filter disc.

The filter element entity using and installing steps are as follows:

the method includes the steps of disassembling a filter shell.

Secondly, the well assembled filter element is inserted into the oil inlet of the filter (the rubber ring on the filter element is inspected to be intact before insertion).

And thirdly, the filter element is well butted with the oil inlet of the filter.

And fourthly, installing a filter shell.

After the filter is blocked, the filter element is only needed to be taken out, the filter element is decomposed, and the filter disc is cleaned or replaced.
