Abstract
The utility model is related to a kind of oil absorption filter for development machine oil pump, including one the housing with oil-out and oil inlet, hollow filter core is provided with housing, it is characterized in that being socketed with an absorbing cylinder in case inside, there is certain interval between absorbing cylinder and filter core, the import communicated with housing oil inlet is provided with absorbing cylinder bottom, being sequentially sticked on the inwall of absorbing cylinder there are multiple magnetic patch, in the core cavity bottom of filter core equipped with a bar magnet.When specifically used, after fluid enters oil absorption filter through oil inlet, magnetic patch on absorbing cylinder is by the larger iron powder adsorption of particle in fluid, the another less iron powder of granularity for having part to enter filter core is again by by the bar magnet absorption of its bottom, fluid is finally suctioned out through oil-out again, and whole process is adsorbed by two-stage, strengthens the filtering to iron powder, make fluid cleaner, improve the operating efficiency of tunneling machine hydraulic system.
Description
Technical field
The utility model belongs to filtering separation device technical field, is related to a kind of oil suction for development machine oil pump and filters
Device.
Background technology
Tunneling machine hydraulic system failure 70%~80% is relevant with hydraulic oil pollution, in order to improve oil cleanliness, reduces
Hydraulic system fault, is provided with oil absorption filter in hydraulic system.It is equipped with inside existing development machine oil pump oil absorption filter
Magnetic bar, but this inner magnet bar be only capable of adsorbing by filter core and enter filter interior the less iron powder of granularity, and
The larger iron powder of some granularities can still adhere on the outside of filter core and block filter core, influence hydraulic work system.
Utility model content
The purpose of this utility model be to overcome the shortcomings of prior art exist there is provided it is a kind of it is rational in infrastructure, easy to operate,
The oil absorption filter for development machine oil pump of good filtration effect.
For realizing that the technical scheme of the utility model purpose is as described below.
A kind of oil absorption filter for development machine oil pump, including a upper and lower part have oil-out and oil-feed
The cylindrical housing of mouth, provided with a hollow filter core in housing, the upper end of filter core is cased with by-passing valve, is equipped with the upper end of housing
End cap, an absorbing cylinder is socketed with case inside, between absorbing cylinder and filter core have certain interval, be provided with absorbing cylinder bottom with
The import that housing oil inlet is communicated, being sequentially sticked on the inwall of absorbing cylinder has multiple magnetic patch, is equipped with the core cavity bottom of filter core
A piece bar magnet.
When the utility model is specifically used, fuel tank adpting flange is connected by screw with oil box, oil absorption filter housing
Lower end oil inlet stretches into fuel tank, and upper end oil-out is connected to after hydraulic pump, hydraulic pressure pump startup, and fuel tank inner fluid enters through oil inlet
The larger iron powder adsorption of particle in fluid is separately had part to enter filter core by the magnetic patch on oil absorption filter absorbing cylinder, absorbing cylinder
The less iron powder of granularity is again by by the bar magnet absorption of its bottom, and fluid is finally suctioned out via oil-out again, and whole process passes through two
Level absorption, strengthens the filtering to iron powder, makes fluid cleaner, in order to avoid because iron powder damages hydraulic means.
Compared with prior art, the utility model has the advantages that reasonable, simple in construction, using effect novel in design is good,
Due on absorbing cylinder and being respectively equipped with magnetic patch and bar magnet two-stage adsorption structure on filter core, absorption can be by the iron in fluid twice
Powder is effectively adsorbed, and is reduced filter core blocking, is improved filter quality, effectively Hydraulic Elements can be protected not to be damaged, improve pick
Enter the operating efficiency of machine hydraulic system.
Brief description of the drawings
Fig. 1 is the structural representation of one specific embodiment of the utility model.
The title of each numeral mark is respectively in accompanying drawing：1- end caps, 2- by-passing valves, 3- filter cores block signalling generator, 4- fuel tanks
Adpting flange, 5- filter cores, 6- absorbing cylinders, 7- housings, 8- oil inlets, 9- oil-outs, 10- magnetic patch, 11- bar magnets.
Embodiment
Referring to accompanying drawing, the oil absorption filter described in the utility model for development machine oil pump is by housing 7, filter core 5, bypass
The components such as valve 2, end cap 1, absorbing cylinder 6 are constituted.Filter core 5 is located on the inside of housing 7, filter core 5 and is cased with by-passing valve 2.End cap 1 is connected
In the upper end of housing 7, housing 7 is provided with oil inlet 8 and oil-out 9, and wherein oil inlet 8 is located at the bottom of housing 7, oil-out 9
In the top of housing 7, the top opposite side of housing 7 blocks signalling generator 3 provided with filter core, causes pressure when the eyelet of filter core occurs to block
When power reaches certain value, by-passing valve 2 starts, it is to avoid hydraulic pump is emptied.Absorbing cylinder 6, absorbing cylinder 6 are socketed with the inner side of housing 7
Lower ending opening, and the position consistency of aperture position and housing oil inlet 8, are provided with a number of magnetic patch on the inwall of absorbing cylinder 6
10.The bottom of housing 7 is equipped with bar magnet 11.
During practical application, oil absorption filter bottom oil inlet 8 is accessed into fuel tank, oil-out 9 is connected to hydraulic pump；Hydraulic pump
After startup, the magnetic patch 10 that fuel tank inner fluid enters through oil inlet 8 on the absorbing cylinder 6 of oil absorption filter, absorbing cylinder 6 is by fluid
The larger iron powder adsorption of grain, the less iron powder of granularity for separately having part to enter filter core 5 will be inhaled by the bar magnet 11 of the bottom of filter core 5 again
Attached, fluid is finally sucked out via oil-out 8 again, and whole process is adsorbed by two-stage, is strengthened the filtering to iron powder, is made fluid
It is cleaner, it is to avoid to damage the situation of hydraulic means because iron powder is adhered to and occur, improve the work effect of tunneling machine hydraulic system
Rate.
