Description
Technical field
A kind of filter core is the utility model is related to, particularly a kind of high-precision multi-stage filter core.
Background technology
Oil contamination directly affects the functional reliability of hydraulic system and the service life of element.Data at home and abroad shows,
The failure of hydraulic system about 70-80% is due to caused by oil contamination.Filter is as particle contamination in interception fluid
Thing, controls the element of oil cleanliness, and very important effect is played in hydraulic system.When the filter core pollutant holding capability of filter reaches
To that need to change or clean filter core during the upper limit to ensure its strainability.As can be seen here, the pollutant holding capability of filter core is to influence filter dimension
An important factor for protecting maintenance period.
The filter core of filters numerous at present realizes that multistage filtering all uses a variety of filter cores or a variety of filter material combination process, will
Different materials are set in together with receiving dirty space, and not only space hold is big, and due to complicated, production efficiency is also low, gives
Enterprise brings very burden.
Utility model content
The purpose of this utility model is：In view of the above-mentioned problems, the utility model is provided a kind of compact-sized and easily torn open
Dress while the good high-precision multi-stage filter core of filterability.
The technical solution adopted in the utility model is as follows：
A kind of high-precision multi-stage filter core, including filter paper assembly, are arranged on the upper edge cap assembly on filter paper assembly top, are arranged on
The bottom end cover of filter paper assembly bottom and the inner frame being arranged on the inside of filter paper assembly, the filter paper assembly by setting successively from outside to inside
Lining net, filter paper a, lining net, filter paper b, lining net, filter paper c and lining net compacting, the filter paper a filtering accuracies put are 20 μm, filter paper b filterings
Precision is 10 μm, and filter paper c filtering accuracies are 3 μm, and lining net is the zinc-plated net of 20 mesh.
Preferably, the upper edge cap assembly includes the upper end cover and grommet welded together.
Preferably, the upper end cover upper end is provided with groove, and O-ring is provided with groove.
Preferably, inner frame and the filter paper assembly is adhesively fixed with upper edge cap assembly and bottom end cover.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
A kind of high-precision multi-stage filter core in the utility model, 4 layers of lining net 4 are separated by filter paper a, filter paper b and filter paper c
Mode be all pressed into one layer by filter paper former, so as to form filter paper assembly, then make filter core, make very quick
It is convenient, and the space of very little is only needed, add the compactedness of filtration device structure.
A kind of high-precision multi-stage filter core in the utility model, lining net, filter paper a filtering accuracies are used as using the zinc-plated net of 20 mesh
For 20 μm, filter paper b filtering accuracies are 10 μm, and filter paper c filtering accuracies are 3 μm, ensure that filtering accuracy, while can effectively accommodate
Pollution residue, so as to improve the dirty rate of receiving of filter core, extend the filter element replacing cycle, reduce damage caused by hydraulic test maintenance downtime
Lose.
