Abstract
The utility model relates to a novel concrete pump sealing element for a concrete pump. The novel concrete pump sealing element for the concrete pump comprises a sealing element body, wherein a connecting hole is arranged in the middle of the sealing element body, a lip opening of the sealing element body is a smooth slope or a cambered surface, and a groove is arranged on the outer wall of the sealing element body. The novel concrete pump sealing element for the concrete pump is free of mingled foreign matter, operation is smooth, service life is long, production cost is low, and working efficiency is high.
Description
Technical field
The utility model relates to a kind of seal connector, is specifically related to a kind of concrete pump piston Sealing.
Background technique
Concrete pump is very important engineering mechanical device, in concrete pump delivering concrete process, driving concrete pump pump head by piston rod moves reciprocatingly in carrying cylinder, U-shaped lip and the interference fit of carrying cylinder (the interior 5mm of the large conveying cylinder of lip diameter of general concrete pump piston) by the concrete pump piston, concrete pump is pushed out conveyance conduit, carry out concrete conveying operation.
The production material of concrete pump piston is the macromolecule elastomeric materials such as rubber or polyurethane, its existing structure be one with the uniform section through hole ring bodies of U-shaped lip.In the process of delivering concrete, the phenomenon of horsestone or other aggregates (hereinafter to be referred as foreign matter) often appears in the U-shaped lip of concrete pump piston, in case there is foreign matter to enter lip, can cause immediately the local compression of lip to increase, lip is nonelastic, forms the situations such as serious eccentric wear, seaming of concrete pump piston.Reduce rapidly the working life of concrete pump piston simultaneously, do not reach concrete conveyance side's amount of expectation.Even scuffing of cylinder bore can occur, carry cylinder the situation such as to scrap, cause direct economic loss, increase cost of production.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of foreign to be mingled with, move smooth and easy, long service life, cost of production is low, the concrete pump of high working efficiency is with concrete pump piston Sealing.
Technological scheme: in order to solve the problems of the technologies described above, a kind of concrete pump described in the utility model concrete pump piston Sealing, it comprises seal body, in the middle of described seal body, be provided with attachment hole, the lip of described seal body is level and smooth inclined-plane or cambered surface, is provided with groove at the outer wall of described seal body.
Be provided with circular arc chamfering in described lip outer end, this circular arc chamfering is less than R3.
Described circular arc chamfering is R1.5.
Described lip becomes 7 ° with horizontal plane, and be connected hole wall and become 60 °.
Described seal body is annular.
Described groove is annular groove, and this annular groove is at least one.
Described seal body adopts the macromolecule elastomeric materials such as rubber or polyurethane.
The utility model changes the U-shaped structure of lip of original concrete pump piston Sealing into the inclined-plane of lip or seamlessly transitting of cambered surface, and formation face contacts, and thoroughly stops to be mingled with the phenomenon of foreign matter; Lip maximum diameter place at concrete pump piston Sealing, adopt small arc-shaped chamfering (chamfering circular arc is less than R3), so that concrete pump piston Sealing enters when carrying cylinder is more smooth and easy, reduce lip and the rubbing surface of carrying cylinder, reduced the heat that produces in the working procedure, the working life that has prolonged concrete pump piston Sealing and carried cylinder, reduced cost of production, improved working efficiency.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the lip of seal body of the present utility model adopts level and smooth inclined-plane or cambered surface, the contact of formation face thoroughly stops to be mingled with the phenomenon of foreign matter; Lip maximum diameter place at piston seal, adopt the small arc-shaped chamfering, it is entered when carrying cylinder more smooth and easy, reduce lip and the rubbing surface of carrying cylinder, reduced the heat that produces in the working procedure, the working life that has prolonged concrete pump piston Sealing and carried cylinder, reduced cost of production, improved working efficiency.
