Abstract
The utility model discloses a gear pump leaks structure, including sealing member and sealing member outer lane, wherein, the sealing member outer lane is inlaying of wave structure and locates in the sealing member outward flange, the one end of sealing member outer lane has both sides and respectively has a plush copper, the utility model discloses sealing member outer ring struction change that will be ordinary is curve type to increase in thickness to 1.96cm with the sealing member outer lane. Carry high leakproofness through increasing the compression ratio, adopt curve type can guarantee not grow and influence the performance of sealing member too of packing rate simultaneously under the prerequisite that improves the compression ratio to more be applicable to the leakproofness under high -voltage pulse's the operating mode.
Description
Technical field
This utility model relates to mechanical field structure-design technique field, in particular for a kind of gear pump leakage structure.
Background technology
Swept volume change that gear pump is dependent on being formed between pumping cylinder and meshing gear and mobile carry liquid or so as to the drum pump of supercharging, when different motor speeds and output pressure be there is certain impact at high temperature and low temperature by produced pulsed pressure in sealing member sealing effectiveness, thus affecting the whole work efficiency of gear pump.And gear pump exists leakage under high pressure, high/low temperature, therefore, the leakage problem improving gear pump is particularly important.
Utility model content
In order to solve gear pump high pressure, high/low temperature environment under there is leakage phenomenon, this utility model provides a kind of gear pump leakage structure.
For reaching above-mentioned purpose, this utility model provides a kind of gear pump leakage structure, including sealing member and sealing member outer ring, wherein, described sealing member outer ring undulate structure be embedded in described sealing member outward flange, one end of described sealing member outer ring has both sides and respectively has a plush copper.
Said gear pump leakage structure, wherein, described sealing member outer ring cross sectional shape is I-shaped structure.
Said gear pump leakage structure, wherein, the described sealing member outer ring curved type structure of right-hand member.
Said gear pump leakage structure, wherein, the mounting groove of wavy shaped configuration is offered in described sealing member and installation place, described sealing member outer ring.
Said gear pump leakage structure, wherein, the size of the left end of the size of described mounting groove and described sealing member outer ring matches.
Said gear pump leakage structure, wherein, the thickness of described sealing member outer ring is 1.96cm.
The beneficial effects of the utility model are:
Common sealing member outer ring structure is changed to shaped form by this utility model, and increases the thickness of sealing member outer ring to 1.96cm.Improving sealing by increasing compression ratio, adopt shaped form can ensure that under the premise improving compression ratio filling rate will not excessively become big and affect the performance of sealing member simultaneously, and is more suitable for the sealing under the operating mode of high-voltage pulse.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated:
Fig. 1 is the gear pump leakage structure schematic diagram of prior art；
Fig. 2 is the sectional view of the sealing member outer ring of prior art；
Fig. 3 is the structural representation of gear pump leakage structure of the present utility model；
Fig. 4 is the sectional view of sealing member outer ring in this utility model.
Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as restriction of the present utility model.
Embodiment
Refer to shown in Fig. 3 and Fig. 4, a kind of gear pump leakage structure of the present utility model, including sealing member 1 and sealing member outer ring 3, wherein, sealing member outer ring 3 undulate structure be embedded in sealing member 1 outward flange, one end of sealing member outer ring 3 has both sides and respectively has a plush copper 4.
This utility model also has implementation below on the basis of the above, continuing with referring to shown in Fig. 3 and Fig. 4,
In further embodiment of the present utility model, sealing member outer ring 3 cross sectional shape is I-shaped structure.
In further embodiment of the present utility model, the curved type structure of sealing member outer ring 3 right-hand member 31, add sealing property.
In further embodiment of the present utility model, the mounting groove (not shown) of wavy shaped configuration is offered in sealing member 1 and installation place, sealing member outer ring 3.
In further embodiment of the present utility model, the size of the left end 32 of the size of mounting groove and sealing member outer ring 3 matches.
In further embodiment of the present utility model, the thickness D2 of sealing member outer ring 3 is 1.96cm.
User can according to following description further insight characteristic of the present utility model and function,
As depicted in figs. 1 and 2, sealing member 1 profile adopts square cross face thickness D1 in the structure of 1.74cm, and sealing member outer ring 2 is embedded in sealing member 1.
Shown in Fig. 3 and Fig. 4, have changed sealing member outer ring 3 profile is shaped form, and adds the thickness of sealing member outer ring 3 to 1.96cm simultaneously.
Improve sealing by increasing compression ratio, and adopt shaped form can ensure that will not excessively the becoming big of filling rate affects the performance of sealing member under the premise improving compression ratio, and be more suitable for the sealing under the operating mode of high-voltage pulse.
The foregoing is only this utility model preferred embodiment; not thereby embodiment of the present utility model and protection domain are limited; to those skilled in the art; the equivalent replacement done by all utilization this utility model description and diagramatic content and the obtained scheme of apparent change should be can appreciate that, all should be included in protection domain of the present utility model.
