Description
Technical field
The utility model belongs to field of rubber technology, relates to a kind of concrete piston.
Background technique
At present, rubber concrete piston is the vitals of construction engineering and drilling machinery cement slurry transfer pump, and it is reciprocating in the media such as cement slurry, cement slurrypump is delivered to eminence, plays seal action at a distance simultaneously, prevent cement slurry from spilling.The assembly type cement slurry concrete piston of prior art is because heat-resisting quantity is poor, easily hydrolyzed, friction factor large, and working life is short; Wear resistance is general, and tear resistance is not as good as polyurethane, and working life is short, has a strong impact on the working efficiency of equipment.For this reason, need a kind of concrete piston, solution heat-resisting quantity is poor, easily hydrolyzed, friction factor large, and working life is short, and wear resistance is poor, tear resistance is poor, have a strong impact on the problems such as the working efficiency of equipment, make it have good resistance to high temperature, resistant to hydrolysis performance, wear-resisting property and tear resistance, reduce friction factor, increase working life, improve the working efficiency of equipment.
Model utility content
The purpose of this utility model is to provide a kind of concrete piston, solution heat-resisting quantity is poor, easily hydrolyzed, friction factor are large, working life is short, wear resistance is poor, and tear resistance is poor, has a strong impact on the problems such as the working efficiency of equipment, make it have good resistance to high temperature, resistant to hydrolysis performance, wear-resisting property and tear resistance, reduce friction factor, increase working life, improve the working efficiency of equipment.
The utility model provides a kind of concrete piston on the one hand, comprise rubber body, layer of fibers is provided with in rubber body, rubber body is set to loop configuration, the upper outside of rubber body is set to inverted trapezoidal, the upper inner of rubber body is provided with the hollow space of inverted trapezoidal, the lower outside of rubber body is provided with the protruding structure of two circle rectangles, rubber body between the protruding structure of two circle rectangles is set to cylinder annular, the lower inside of rubber body is provided with columniform hollow space, is provided with the hollow transitional part of inverted trapezoidal between the hollow space of the inverted trapezoidal inside rubber body and columniform hollow space.
Compared with prior art, the utility model has the following advantages:
The utility model provides a kind of concrete piston and method for preparing raw material thereof, solution heat-resisting quantity is poor, easily hydrolyzed, friction factor are large, working life is short, wear resistance is poor, and tear resistance is poor, has a strong impact on the problems such as the working efficiency of equipment, make it have good resistance to high temperature, resistant to hydrolysis performance, wear-resisting property and tear resistance, reduce friction factor, increase working life, improve the working efficiency of equipment.It significantly improves the tear resistance of rubber, and significantly improves the wear resistance of rubber; It can reduce the Electrostatic Absorption between fiber, thus is conducive to the dispersion of fiber in rubber; It can improve the dispersion of fiber in rubber.
Accompanying drawing explanation
Fig. 1 is the structural representation of concrete piston of the present utility model.
In figure, 1 is rubber body, and 2 is protruding structure.
Embodiment
In order to understand the utility model better, below in conjunction with specific embodiment, the utility model is explained in detail.But, obviously can carry out different modification and remodeling to the utility model and not exceed the wider spirit and scope of the utility model of appended claims.Therefore, following examples have exemplary and hard-core implication.
Embodiment:
A kind of concrete piston, comprise rubber body 1, rubber body 1 is set to loop configuration, layer of fibers is provided with in rubber body 1, the upper outside of rubber body 1 is set to inverted trapezoidal, the upper inner of rubber body 1 is provided with the hollow space of inverted trapezoidal, the lower outside of rubber body 1 is provided with the protruding structure 2 of two circle rectangles, rubber body 1 between the protruding structure 2 of two circle rectangles is set to cylinder annular, the lower inside of rubber body 1 is provided with columniform hollow space, is provided with the hollow transitional part of inverted trapezoidal between the hollow space of the inverted trapezoidal inside rubber body 1 and columniform hollow space.
Concrete piston of the present utility model and method for preparing raw material thereof; the outside of the rubber body 1 of its concrete piston can arrange texture layer; its protruding structure 2 can arrange protruding particle, and the inside of its rubber body 1 can arrange protective layer, and the upper and lower of its rubber body 1 can arrange installation notch.After it adds layer of fibers in rubber body 1, the tear resistance of rubber can be significantly improved, and significantly improve the wear resistance of rubber.
