Abstract
The invention discloses a kind of full composite material pistons, belong to piston technical field.Including core and elastomer, the core uses high strength glass fiber, the elastomer and core to form using integrated vulcanizing；The present invention uses high strength glass fiber composite material core, and stronger with elastomer-bonded, weight only has the 1/3 of conventional metals steel core piston, easy to assembly, reduces transportation cost.
Description
Technical field
The invention belongs to piston technical fields, and in particular to a kind of full composite material piston.
Background technique
In traditional piston, using metal steel core, the macromolecular elastomer of metal steel core and outer end bonds not firm, structure
It is unstable；And in the environment that piston is used for acid-base solution, metal steel core is easy to be corroded, and causes steel core and elastomer
Premature decomposition is peeled off.Metal steel core piston weight is big simultaneously, and production efficiency is low, and processing cost is high, and assembly is inconvenient, transportation cost
It is high；Since it also easily causes the uneven wear of piston from weight of hanging down, to influence the use of piston.
Summary of the invention
Aiming at the problem that shortcomings and deficiencies in the prior art, the invention proposes a kind of full composite material pistons, using height
Strength-Glass-Fibre composite material core, stronger with elastomer-bonded, weight only has the 1/3 of conventional metals steel core piston, dress
With conveniently, transportation cost is reduced.
The technical solution adopted by the present invention to solve the technical problems are as follows:
A kind of full composite material piston, including core and elastomer, the core use high strength glass fiber, the elastomer
It is formed with core using integrated vulcanizing.
Further, the core is equipped with several tooth sockets, and elastomer is equipped with the protrusion with tooth socket fit.
Further, the elastomer uses casting type polyurethane.
Further, plexiglas fiber can be used in the high strength glass fiber.
The invention has the following beneficial effects: cores to be process using high strength glass fiber, although current is compound
The single cost of material and metal maintain an equal level, but due to light weight, production flow speed is fast, and efficiency greatly improves, and cost reduces still
New product profit increases；And composite material and elastomer integrated vulcanizing form, and bond effect is more preferable, and structure is more stable；It is high-strength
Spend corrosion of the glass fibre compared to metal more resistant to various acid-base solutions；There was only metal material using the piston weight of composite material
1/3, storage and transportation is convenient, easy to assembly, reduces transportation cost, is suitble to oil gas field desert, field work.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is core schematic diagram of the present invention；
Fig. 3 is pistons work process schematic.
Specific embodiment
Detailed description of the preferred embodiments with reference to the accompanying drawing.
As shown in Figure 1, a kind of full composite material piston, including core 1 and elastomer 2, the core 1 use high-strength glass
Glass fiber, the elastomer 2 are formed with core 1 using integrated vulcanizing.
Above-mentioned piston uses high strength glass fiber core 1, is easier with 2 sulfidization molding of elastomer, the two bond effect
It is more preferable compared to metal steel core piston.And it is light-weight, easy to assembly, transportation cost is low.The core 1 of composite material compares metallic steel
Core processing is easier, and production efficiency greatly improves.
As shown in Fig. 2, the core 1 is equipped with several tooth sockets 11, elastomer 2 is equipped with the protrusion cooperated with tooth socket 11
21, so that it is stronger to combine core 11 with elastomer 12, piston structure is more stable.
The elastomer 2 uses casting type polyurethane, and wear-resisting property is good.
Plexiglas fiber can be used in the high strength glass fiber, and resistance to various acid-base solutions avoid metal steel core and exist
It works under complex environment perishable, steel core and elastomeric material premature decomposition is caused to peel off.
As shown in figure 3, driving ram 33 by crank 31, connecting rod 32, keep piston 30 reciprocating in cylinder sleeve, piston 30
Reciprocating motion change the volume of cylinder sleeve 2, and make to keep certain pressure in fluid cylinder, be realized by dump valve 34 and inlet valve
The course of work of liquid is pumped, in the process, piston has primarily served three sealing, righting, wiping effects.
The present invention tests in following operating condition: using temperature :≤80 DEG C, using medium: crude oil/water, pH value 5-11, work
Pressure :≤37MPa(is carried as 5537MPa through pressure test stress surface) meet safety coefficient；Its working in reciprocating mode total length
620mm, the frequency≤80 time per minute.Experiment proves that the normal use under the above operating condition, average life >=400 hour.
Inventive piston is full composite material, and core is compound using high strength glass fiber or similar high-performance fiber
Material, it is light-weight, avoid metal steel core piston as weight from hang down and caused by piston lower portion and barrel wear it is too fast, i.e., singly
The problem of side is worn, the service life is longer.
The basic principles, main features and advantages of the present invention have been shown and described above.The present invention is not by upper
The limitation of embodiment is stated, the above embodiments and description only illustrate the principle of the present invention, is not departing from the present invention
Various changes and improvements may be made to the invention under the premise of spirit and scope, these changes and improvements both fall within claimed
In the range of invention.The claimed scope of the invention is defined by appended claims and its equivalent.
