The structural representation of one embodiment of the built-up gear pump that Fig. 1 provides for this utility model.
The structural representation of one embodiment of the oil-in of the built-up gear pump that Fig. 2 provides for this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Shown in Figure 1, built-up gear pump, including pump case 1, rotating shaft 7, rotor 6, rotating shaft sliding bearing 10, oil-in 2, oil-out 12 and rotator seat 3, rotator seat 3 is connected with rotating shaft 7, rotor 6 is arranged in rotator seat 3, rotator seat 3 is arranged in the runner 11 of pump case 1, is provided with end cap 5 in the outer end of pump case 1.Rotating shaft sliding bearing 10 is a wear-resisting graphite piece, it is an axle sleeve shape, and a part embeds in the bearing block of pump case 1, and rotating shaft 7 is through rotating shaft sliding bearing 10, so rotating shaft 7 rotates in rotating shaft sliding bearing 10, and the end face of rotating shaft sliding bearing 10 also functions to the effect of plain thrust bearing simultaneously.
The rotating shaft 7 of built-up gear pump of the present utility model can be driven by pulley apparatus 100 by motor (not representing in figure), and certain rotating shaft 7 can also directly be connected with motor.When rotating shaft 7 rotates, owing to rotator seat 3 and rotating shaft 7 connect as one, then rotator seat 3 rotor driven 6 rotates thus forms negative pressure, liquid (such as oil) is sucked from oil-in 2, enter in rotator seat 3 and rotor 6, the engagement compression of rotator seat 3 and rotor 6 forces the fluid into oil-gas separation chamber, and the liquid oil after separation is discharged through oil-out 12.When built-up gear pump work, between the face that rotor 6, rotator seat 3 and end cap 5 contact, certain friction can be produced.
Referring back to Fig. 1, in this embodiment, a rotor pads 9 it is provided with between the left side of the right side of rotating shaft sliding bearing 10 and rotator seat 3, a spring 8 it is provided with between rotor pads 9 and rotator seat 3, this spring is a helical spring, and its one end can be enclosed within the end that the left end of rotator seat 3 is prominent and prop up the left end (face) of rotator seat 3.Wherein, the right side of rotor pads 9 is provided with a groove 91 corresponding with the other end of spring 8 so that this end of spring 8 can be in embedded groove 91.So, spring 8 is just compressed between the right side of rotor pads 9 and the left side of rotator seat 3.The size of above-mentioned groove 91 makes spring 8 be in interference fit when being embedded in, so, when built-up gear pump of the present utility model operationally, due to spring with the interference fit of groove to rotate at described rotor pads, solving rotor pads well has the phenomenon not rotated.
Describe as mentioned above, when built-up gear pump work is to the regular hour, friction can be produced between the face that rotor 6, rotator seat 3 and end cap 5 contact, rotator seat 3, rotor 6, the meniscus level of rotor endcap 5 can be worn and torn, so gap before them can increase, particularly as being gap 563 and 53 increase shown in figure, and, owing to above-mentioned spring 8 is in compressive state, once gap produces, the tension force of spring 8 can compensate the gap of generation by drive rotor seat 3 to the right, makes built-up gear pump be in normal and efficient duty.Meanwhile, rotor pads 9 is promoted by the thrust of spring 8 to the left so that can form certain gap 89 between pad 9 and rotator seat 3, prevents from rubbing between the two, thus improves their service life.
The structural representation of one embodiment of the oil-in of the built-up gear pump that Fig. 2 provides for this utility model.See Fig. 2, an intake screen assembly 20 it is provided with in the runner of oil-in 2, in the present embodiment, intake screen assembly 20 is a cylindric reticulate body, it includes the netted end face 202 being positioned at left end, side 201 and the netted end face 203 of right-hand member, these faces all can have the impurity filtering the liquid flow through, can be stayed in intake screen assembly 20 by the impurity of filtration simultaneously.Be connected by cross section at seal member 21 and the one of oil-in 2 at the most netted end face 120 and play sealing function, in order to filter the liquid sucked from oil-in 2, filtered by side 201 with the impurity of liquid inflow and block.
But, existing built-up gear pump does not has suitable net-filter assembly and the filter screen sealing member coordinated with this net-filter assembly, and particularly, sealing member separates with filter screen, thus result in the problem that dismounting filter screen sealing member comes off and loses, and, sealing property is the most poor.Therefore, in this utility model, intake screen assembly 20 and sealing member 21 use line with rubber integrated sealing mode to link into an integrated entity.The end face 203 of the right-hand member of intake screen assembly 20 is fixed by screw 41 with filter cover 50, so, when opening filter cover 50, taking intake screen assembly 20 out of simultaneously, sealing member 21 is owing to being to use line with rubber integrated sealing mode to link into an integrated entity also to be taken out of together, so, sealing member 21 would not come off and lose, meanwhile, sealing member 21 uses oil resistant rubber seal member, and sealing property is more preferable.
Further, since existing built-up gear pump oil-in does not has the device of corresponding filtering metal impurity, result in impurity and enter pump chamber, damage the situation of built-up gear pump, or metal impurities stick to screen surface and cause filter screen to get rusty blocking flow-reduction.
Referring back to Fig. 2, embodiment of the present utility model also includes a magnet component 30, and it is a Magnet.Magnet component 30 is arranged in intake screen assembly 20, can be held by the metal impurities with liquid.In order to realize preferably effect, magnet component 30 is preferably disposed on the central part of intake screen assembly 20, for this this utility model central part in the enclosed construction of intake screen assembly 20, a piece oil baffle 40 is set, magnet component 30 is arranged on oil baffle 40, being fixed on support bar 40 by screw 31, its concrete fixed position can conveniently adjust.Support bar 40 is L-type, and one arm is parallel with filter cover 50, is fixed on filter cover 50 by screw 41.This arm is provided with a through hole, and a protrudent pin 501 of filter cover 50 can penetrate this through hole and fix this arm further.
Owing to increasing magnet component 30 in intake screen assembly 20, when oil product flows through this magnet assemblies, the irony impurity in oil product can be attracted on Magnet, efficiently solves irony impurity and enters pump chamber, damages the technical problem of sundstrand pump.
The principle identical with intake screen assembly 20 is described above, in order to filter the impurity of the liquid will discharged from oil-out 12 further, an outlet net-filter assembly be may further be provided, and outlet net-filter assembly is arranged at described oil-out to filter the liquid (oily) discharged from described oil-out.Concrete structure mode need not describe again.
On the basis of the embodiment originally making utility model is described, for those skilled in the art, do not spend performing creative labour, still can make embodiment to adjust as follows or change to realize the purpose of this utility model equally:
1, above-mentioned outlet net-filter assembly can also save.
2, in some cases, rotor pads 9 can be connected with axle rotating shaft sliding bearing 10.
3, the end face 203 of the right-hand member of intake screen assembly 20 can not be fixed with filter cover 50.
The above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those skilled in the art is in technical scope disclosed in this utility model; the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with described scope of the claims.
