Description

Piston seal

Technical Field

The utility model relates to a piston seal especially relates to a concrete pump truck concrete piston, and it belongs to piston technical field.

Background

The existing concrete piston of the concrete pump truck in the market has the defects of simple process and design, the piston made of the traditional material cannot adapt to the severe use environment of the concrete pump truck, so that the piston rapidly loses efficacy in a cylinder body when in use, the frequent replacement of the concrete piston has great influence on the work efficiency, the use cost is increased, and much time is wasted.

The novel concrete piston which can effectively solve the problem of non-wear resistance of the traditional concrete piston and greatly prolong the service life of the concrete piston is urgently needed to be researched and developed, and the aim of improving the working efficiency is fulfilled.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the not enough of existence among the above-mentioned prior art, provide a piston seal spare.

The utility model provides an above-mentioned technical problem's technical scheme as follows:

the utility model provides a piston seal spare, includes the piston body, piston body below is equipped with the bellied sealing strip of annular, be equipped with the fluting with the sealing strip disconnection on the sealing strip, the fluting is perpendicular with the sealing strip.

The sealing strips are more than two, an oil guide groove is formed between every two adjacent sealing strips, and the grooves in the two adjacent sealing strips are distributed in a staggered mode.

The height of the sealing strip is at least 5 mm.

The number of the grooves is more than one pair.

The width of the slot is 0.5-1.5 mm.

The width of the slot is one millimeter.

The depth of the groove is the distance between the piston body and the maximum diameter of the sealing strip.

The sealing strip is two, and the contained angle between the adjacent fluting on every sealing strip is 90, and the contained angle between the adjacent fluting on two sealing strips is 45.

Compared with the prior art, the beneficial effects of the utility model are that: the problem that the feeding square amount of the building concrete pump truck in the market is small is effectively solved through slotting, so that the pumping square amount of the building concrete pump truck is increased, the frequent replacement of concrete pistons of the concrete pump truck is reduced, and the problems of reducing the cost, improving the efficiency and saving the energy consumption are solved.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a front view of the structure of the present invention.

In the figure, 1, a piston body; 2. a sealing strip; 3. grooving; 4. and an oil guide groove.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

The utility model provides a piston seal, includes

piston body

1, 1 below of piston body is equipped with annular bellied sealing strip 2, be equipped with the fluting 3 with sealing strip 2 disconnection on the sealing strip 2, fluting 3 is perpendicular with sealing strip 2, and fluting 3 is as shown in figure 1 or figure 2.

In the use, the piston is because of its abominable operational environment and under high temperature high pressure, and the concrete piston can take place to produce the deformation by the influence of pressure in the jar, and concrete piston top contacts with concrete, and the below is connected with connecting rod and cavity, and the upper end propelling movement concrete can play fine sealed effect, and when back stretching out and drawing back, the water in the cavity and emollient can pass through the effectual concrete piston seal area that gets into of vertical fluting 3, play fine lubricated effect.

The sealing strip 2 is more than two, forms between two adjacent sealing strips 2 and leads oil groove 4, and fluting 3 crisscross distribution on two adjacent sealing strips 2, the high wear-resisting and good self-lubrication nature of product and the scientific oil groove 4 design of leading can effectual increase building square volume with reduce the harm to the cylinder body, can reach reduce cost and raise the efficiency, reduce the energy consumption, also improve to some extent to the environment simultaneously.

The height of the sealing strip 2 is at least 5 mm.

The number of the slots 3 is more than one pair.

The width of the slot 3 is 0.5-1.5mm, and the use effect is extremely poor when the width of the slot 3 is less than 0.5mm or more than 1.5 mm.

The effect is best when the width of the slot 3 is one millimeter.

The depth of the slot 3 is the distance between the piston body 1 and the maximum diameter of the sealing strip 2.

Sealing strip 2 is two, the contained angle between the adjacent fluting 3 on every sealing strip 2 is 90, the contained angle between the adjacent fluting 3 on two sealing strips 2 is 45, according to scientific analysis, divide 90 to set up fluting 3 on annular sealing strip 2, the contained angle between the adjacent fluting 3 from top to bottom becomes 45 evenly distributed, when the piston uses in the concrete pump truck jar like this, front end propelling movement concrete can play fine sealed effect, when back stretching out and drawing back, water and emollient in the cavity can pass through the effectual concrete piston seal zone that gets into of 45 vertical fluting 3 of unique design, play fine lubricated effect.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
