Present invention relates in general to be used for installing the housing unit of the oil filter assembly that is used for industrial equipment, and be particularly related to such housing unit: this housing unit can prevent that oil just has not been filtered by bypass in housing unit, can be on the whole cross sectional area of oil filter assembly with uniform pressure filtration oil almost, therefore improve filter efficiency significantly and prolonged service life of oil filter assembly, and assembling that helps covering and dismounting, and do not damaging the situation replacing oil filter assembly of oil filter assembly.
Background technology of the present invention
Fig. 7 and Fig. 8 show the conventional housings assembly that is used for installing the oil filter assembly that is used on the industrial equipment.
At first with reference to Fig. 6, housing unit comprises housing 11 and lid 52, thereby lid 52 is assembled to seal casinghousing 11 in the housing 51, and wherein oil filter assembly 10 is inserted in the inside of housing 11.Housing unit with oil filter assembly 10 is installed in filter or industrial equipment.And, by means of entering pipe and outlet, make oil flow through oil filter assembly 10 and be filtered by power, therefore can keep the characteristic of oil or return to oily characteristic.
Oil filter assembly generally includes the multistage filtering body, and these filter bodies are assemblied between interior pipe and the outer tube.Housing unit comprises and covers fixed bar 13, and this fixed bar joins to by interior pipe on the bottom of housing 11 and be fixing, thereby after oil filter assembly 10 is inserted into the inside of housing 11, is assemblied in hermetically on the top of housing 11 covering.
Lid fixed bar 13 comprises spray orifice 13a, 13b, and these spray orifices are formed at the central authorities of bottom in the following manner: oil flows to the upper space 15b by the inner space between spray orifice 13a, 13b and lid fixed bar 13 and the interior pipe from entering pipe.Then, oil arrives lower space 15c by oil filter assembly, and flows out from lower space 15c by means of outlet.
But, in this oil filter assembly, because outer tube and interior pipe are formed by harder material such as hardboard, therefore when oil filter assembly 10 is inserted in the inside of housing 11, between the inwall of oil filter assembly and housing 11, be difficult to realize sealing fully.Therefore, a large amount of oil be not filtered and between oil filter assembly and inwall by bypass, and filter efficiency reduces, the characteristic of oil filter assembly degenerates, and has shortened the service life of oil filter assembly 10 and oil.
In addition, lid fixed bar 13 and lid 12 wait by means of sealing device 13a such as rubber and seal, and still, in repeat to open 12 process cover in order to change oil filter assembly 10, sealing device 13a is tending towards damaging or ruptures and need change it often.
In addition, make the density of oil filter assembly evenly very difficult, and evenly filter oil is also very difficult on the whole cross sectional area of oil filter assembly, because the oil pressure by oil filter assembly is inhomogeneous, therefore filter efficiency has reduced, the characteristic of oil filter assembly degenerated, and shortened the service life of oil filter assembly 10 and oil.

In addition, need be inserted into lid fixed bar 13 in the inner space of interior pipe of oil filter assembly 10, and need in the central authorities of interior pipe fixing easily because cover and during the assembling shell assembly, the inner space of interior pipe is longer when lid fixed bar 13 is inserted into to fix in the housing 51.This has just reduced the Assembling Production rate, and easily causes the damage of oil filter assembly and sealing device 18 and produce oil leaking, and therefore causes inhomogeneous filtration and has reduced filter efficiency.
In addition, as shown in Figure 7 and Figure 8, lid 12 is provided with plurality of projections 12a, and these protuberances make it to form the tight device that contacts with the bottom of housing 51 as compressed oil filter assemblies 10.But the contact area of protuberance 12a is less, thus the bottom of oil filter assembly 10 and housing 51 contact not exclusively, therefore cause inwall and gap oil filter assembly 10 between and the bypass of oil by housing 11, and reduced filter efficiency.
In addition, cover fixed bar 13 and can make and cover 12 and from housing 11, remove by unclamping.But, in the place that lid 12 is fixed to housing 11 firmly, pull down and cover 12 unusual difficulties, so reduced the Assembling Production rate and can cause the damage of sealing device 18.
