Description
Technical field
This utility model belongs to field of mechanical technique, relates to a kind of compressor, intrinsic pressure particularly to a kind of compressor box
Dynamic balance structure.
Background technology
Compressor is a kind of driven fluid machinery that low-pressure gas is promoted to gases at high pressure, and it sucks low from suction nozzle
The refrigerant gas of temperature low pressure, after driving piston to be compressed it by motor rotation, discharges High Temperature High Pressure to exhaustor
Refrigerant gas, provides power for kind of refrigeration cycle, thus realizes kind of refrigeration cycle.Traditional compressor in the course of the work, in casing
There is pressure differential between pressure and inlet pressure, make the piston rod in casing easily wear and tear when moving reciprocatingly, thus
Reduce the service life of compressor, and make noise ratio during compressor operating bigger.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, it is provided that one makes compressor quiet
Pressure balancing structure in the casing that effect is more preferable and service life is longer.
The purpose of this utility model can be realized by following technical proposal: pressure balance knot in a kind of compressor box
Structure, including base and the shell being arranged on base, is provided with casing, described casing is provided with gas in described shell
Cylinder, described cylinder is provided with cylinder cap, described cylinder cap is provided with air inlet, is provided with piston rod in described casing
Assembly, described Piston and rod assembly includes screw, pressing plate, piston ring and connecting rod, it is characterised in that offer on described casing
There is passage one, described cylinder offers passage two, described cylinder cap offers passage three, and described ventilation
Kong Yi, passage two and passage three are interconnected, and described pressing plate and piston ring junction surface are provided with fillet α, described pressure
Plate side is provided with angle of inclination beta, and the end face of described connecting rod is provided with tilt angle gamma and edge is provided with fillet δ.
In this compressor box, the principle of pressure balancing structure is: offer passage on casing, cylinder, cylinder cap respectively
One, being interconnected between passage two, passage three, and three passages, when piston stroking upward, compressor is in aerofluxus shape
State, now in casing, pressure reduces, and air inlet inner refrigerant arrives casing after sequentially passing through each passage；Work as descent of piston
Time, compressor is in suction condition, now in casing pressure increase, the cold-producing medium in casing can through each passage return to into
Cylinder, thus the pressure in guard box body is consistent with air inlet all the time so that compressor muting function operationally is more preferable, and
And make the most easy to wear when moving reciprocatingly in cylinder of piston, add the service life of compressor.
In above-mentioned a kind of compressor box in pressure balancing structure, the radius of described fillet α is 0.8mm, described in incline
The angle of angle beta is 10 degree, and the angle of described tilt angle gamma is 2 degree, and the radius of described fillet δ is 0.3mm.
In above-mentioned a kind of compressor box in pressure balancing structure, described piston ring is answering with PTFE as matrix
Condensation material.
In above-mentioned a kind of compressor box in pressure balancing structure, the material of described cylinder is aluminium alloy 6061 and adopts
Process with hard anodizing and Teflon processes.
Compared with prior art, in this compressor box pressure balancing structure by the pressure in offering each passage and making casing
Power is consistent with air inlet all the time, and improves Piston and rod assembly, make compressor have muting function is good, length in service life excellent
Point.
