Description
Technical Field
The utility model belongs to the technical field of the plunger pump technique and specifically relates to a novel airtight water seal structure of high pressure.
Background
The plunger pump is an important device of the hydraulic system. The volume of the sealed working cavity is changed by the reciprocating motion of the plunger in the cylinder body, so that oil absorption and oil pressing are realized. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency, convenient flow regulation and the like.
Plunger pumps are widely used in applications where high pressure, high flow and flow needs to be regulated, such as hydraulic machines, engineering machinery and ships.
The water seal is an important structure of the plunger pump, is made of common water seal materials, has a limited service life, is simple in structure, is easy to damage and needs to be replaced frequently.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned defect that exists among the prior art, the utility model provides a novel airtight water seal structure of high pressure.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a novel airtight water seal structure of high pressure, includes plunger pump body, water seal, plunger and O shape circle, this internal annular groove that expands outward that is equipped with of plunger pump, the water seal inlays in annular groove, the outside and the plunger pump body interference fit of water seal, the plunger outside and the inboard interference fit of water seal, O shape circle set up between annular groove side and water seal side and O shape circle respectively with plunger pump body and water seal interference fit.
The novel high-pressure sealed water seal structure is characterized in that the water seal is made of a carbon fiber material.
The beneficial effects of the utility model are that, the utility model discloses the water seal outside and body cooperation, inboard and slip plunger cooperation all adopt protruding shape interference fit, and the bottom is supported to both sides with high strength O type circle simultaneously, makes the inside and outside play fine sealed effect, and the water seal adopts special carbon fiber simultaneously, has fine toughness and wearability.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is an enlarged view of the area a in fig. 1.
In the figure, 1 is a plunger pump body, 2 is a water seal, 3 is a plunger, 4 is an O-shaped ring, and 5 is an annular groove.
Detailed Description
In order to more clearly illustrate the technical solution of the present invention, the following provides a further description of the present invention with reference to the accompanying drawings, and obviously, the following described drawings are only one embodiment of the present invention, and for those skilled in the art, other embodiments can be obtained according to the drawings and the embodiment without any creative work, and all belong to the protection scope of the present invention.
The utility model provides a novel airtight water seal structure of high pressure, includes plunger pump body 1, water seal 2, plunger 3 and O shape circle 4, be equipped with outer expanding annular groove 5 in the plunger pump body 1, water seal 2 inlays in annular groove 5, the outside and the plunger pump body 1 interference fit of water seal 2, the plunger 3 outside and the 2 inboard interference fit of water seal, O shape circle 4 sets up between annular groove 5 side and water seal 2 sides and O shape circle 4 respectively with plunger pump body 1 and 2 interference fit of water seal.
The water seal 2 is made of carbon fiber material.
The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the protection scope of the present invention is defined by the claims. Various modifications and equivalents of the invention can be made by those skilled in the art within the spirit and scope of the invention, and such modifications and equivalents should also be considered as falling within the scope of the invention.
