Description
Technical field
The utility model is related to compressor fields, and in particular to a kind of to balance the compressor piston for moving back and forth inertia force.
Background technology
Compressor is a kind of universal machine for improving various gas pressures, is the product having a large capacity and a wide range in mechanical industry
One of.Very extensive application is obtained in many departments of national economy, is almost defended throughout industry, agricultural, communications and transportation, medical treatment
Life, national defence, scientific research or even people's lives many fields, especially in chemical industry, synthesis, coal, oil, construction, ocean
Engineering etc., even more essential power-equipment.And piston is a major part of piston compressor, it and cylinder
Cooperatively form minimum cylinder volume.The quality and the performance of compressor of plunger designs have very big relationship.It is commonly used to be processed into piston
Material has cast aluminium alloy, gray cast iron, steel etc..
The comparison that the weight of piston to be designed is light, to reduce reciprocal inertia force.Compressors more than two row, should be according to inertia
The principle of dynamic balance makes each row piston mass counterweight as possible.In compressor piston design, the low pressure that is generally relatively large in diameter
Grade piston uses cast aluminium to mitigate quality, and the quality of hiigh pressure stage piston is close, to achieve the purpose that balance reciprocal inertia force,
So as to make compressor operation steadily reliable.But sometimes due to low-pressure stage cylinder diameter is larger, piston mass is heavier, and hiigh pressure stage cylinder
Diameter is smaller, and the piston of hiigh pressure stage is difficult to the quality for reaching low-pressure stage piston, and the quality for leading to each row piston is unbalanced, there is compression
Machine can not even running risk.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of compressor work for balancing reciprocating motion inertia force
Plug, allows the piston of major diameter low-pressure stage and the piston of small-bore hiigh pressure stage to reach balanced in quality, reciprocal so as to reach balance
Move back and forth the purpose of inertia force.
Technical problem to be solved in the utility model is realized using following technical solution：
It is a kind of to balance the compressor piston for moving back and forth inertia force, including piston only, the upper surface of the piston only
If there are two symmetrical screw hole, the lower face of piston only is equipped with 6 threaded holes, and the threaded hole is perpendicular to piston only
Lower face, threaded hole be hole countersunk structure, including minor diameter threaded hole and large-diameter thread hole, threaded hole with piston only above and below
The through-hole center of circle of both ends of the surface is distributed for basic point annular array.
The threaded hole is hole countersunk structure, minor diameter threaded hole is first drilled through in piston only lower face, in minor diameter spiral shell
Enlarged diameter on pit drills through large-diameter thread hole.Lead is filled in the minor diameter threaded hole, large-diameter thread hole is connected with screw plug
Sealing, large-diameter thread hole inner wall and screw plug apply and spread thread locking agent, and the piston only lower face after sealing makees vehicle and puts down place
Reason.
It preferably, can be in order to ensure that the mechanical strength of piston and filler can still make each row piston mass balanced
Tungsten or heavy alloy are selected as filler.
Preferably, 6 threaded holes of annular array are provided in the lower face of piston only, and to the minor diameter of threaded hole
The high-density matters such as filling lead in threaded hole, then sealed with screw plug, for simplification of flowsheet, use hexagonal interior made of wolfram steel
Dormant bolt eliminates the vehicle after sealing and puts down processing.Also, sealer and filler are an integral structure in itself, are further protected
Stable connection is demonstrate,proved.
The operation principle of the utility model：It drills on the piston of small-bore hiigh pressure stage, and the material of filling high density degree,
The situation of constancy of volume increases the quality of piston, makes the quality of small-bore hiigh pressure stage piston and the quality of heavy caliber low-pressure stage piston
Equilibrium, so as to achieve the purpose that balance moves back and forth inertia force.Further more, piston common used material density (g/cm3)：Cast aluminium is
2.68, gray cast iron 7.35, steel 7.85.And the density of lead is 11.34, is approximately 4.23 times of cast aluminium, the 1.54 of gray cast iron
Times, 1.44 times of steel, therefore the weighted material of piston can be used as.
The beneficial effects of the utility model are：Make the quality balance of each row piston, balance moves back and forth inertia force, ensures pressure
The even running of contracting machine.The utility model has the advantages of design science, rational in infrastructure.

Specific embodiment
In order to be easy to understand technical means, creative features, achievable purpose and effectiveness of the utility model, under
The attached drawing that face will be combined in the utility model embodiment, carries out the technical scheme in the embodiment of the utility model clear, complete
Ground describes, it is clear that described embodiment is only the section Example of the utility model, instead of all the embodiments.
Embodiment 1
It is a kind of to balance the compressor piston for moving back and forth inertia force, including piston only 1, the piston sheet with reference to Fig. 1-3
The upper surface of body 1 is set there are two symmetrical screw hole, and the lower face of piston only 1 is equipped with 6 threaded holes, and the threaded hole is vertical
In the lower face of piston only, threaded hole is hole countersunk structure, including minor diameter threaded hole 2 and large-diameter thread hole 3, threaded hole
It is distributed by basic point annular array of the through-hole center of circle of 1 upper and lower ends face of piston only.
The threaded hole is hole countersunk structure, minor diameter threaded hole 2 is first drilled through in 1 lower face of piston only, then small
