Abstract
The utility model is related to a kind of Compressor Piston Ring support devices, it includes and compresser cylinder（1）The piston of corresponding matching（2）, in piston（2）It is equipped with one group of annular groove（3）, it is characterised in that：In the annular groove（3）It is interior to be equipped with support ring（4）, in support ring（4）It is equipped with and compresser cylinder（1）The piston ring of inner wall corresponding matching（5）.The utility model is simple in structure, easy to use, manufacturing cost is cheap, can directly use on existing, and the sealing effect being effectively guaranteed between piston ring and compresser cylinder avoids the generation of gas leak phenomenon, has ensured the work efficiency of compressor.
Description
Technical field：
The utility model is related to gas compressor fields, are exactly specifically a kind of Compressor Piston Ring support device.
Background technology：
The quality of compresser cylinder sealing directly affects the work efficiency and site safety of compressor, and cylinder seal is
Ensure by the gap between piston ring packing piston and cylinder, as the important component in compressor, piston ring building ring
Border is high pressure, high temperature, it also plays cloth oil and heat conduction.Due to the influence of working environment and operating mode, piston ring is often
Abrasion, deformation, lose original elasticity, cause it poorly sealed with cylinder minute surface, generate gas leak phenomenon, directly affect compressor
Work efficiency, while temperature can raise, and bring security risk.Since the piston ring more renewed needs certain procurement cycle and phase
How the maintenance cost answered, recover the use function of piston ring within the shortest time, but need not more rering, while can
Meet compressor requirement, become extremely urgent task.
Utility model content：
The utility model is exactly insufficient in the prior art in order to overcome, and provides a kind of Compressor Piston Ring support device.
The utility model provides following technical scheme：
A kind of Compressor Piston Ring support device, it includes the piston with compresser cylinder corresponding matching, is set on piston
There is one group of annular groove, it is characterised in that：In the annular groove be equipped with support ring, be arranged in support ring in compresser cylinder
The piston ring of wall corresponding matching.
Based on the above technical solutions, there can also be technical solution further below：
The support ring is made of stainless steel band, and one group of outwardly triangle is also evenly equipped in support ring
Dog-ear.
Utility model advantage：
The utility model is simple in structure, easy to use, manufacturing cost is cheap, can directly use, carry on existing
The high service life of piston ring, avoids and gas leak phenomenon is generated between piston ring and cylinder, eliminate security risk, ensure
The work efficiency of compressor.
Description of the drawings：
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the A-A sectional views in Fig. 1.
Specific embodiment：
As illustrated in fig. 1 and 2, a kind of Compressor Piston Ring support device, it include with compresser cylinder 1, in compressor gas
The piston 2 of corresponding matching is equipped in cylinder 1, one group of axially spaced distribution is equipped in the mating surface of piston 2 and 1 inner wall of cylinder
Annular groove 3.
It being all provided in each annular groove 3 there are one support ring 4, the support ring 4 is made of stainless steel band, and
It is excessive for camber line that the dog-ear end of the dog-ear 4a, the dog-ear 4a of one group of triangle are also evenly equipped in support ring 4.In the branch
4 outer sheath of pushing out ring is equipped with piston ring 5, and the periphery of the piston ring 5 forms corresponding matching with the inner wall of compresser cylinder 1.
The diameter of the support ring 4 is more bigger 0.5-1mm than 5 diameter of piston ring, passes through the elasticity tension top of support ring 4 itself
Firmly piston ring 5 make its periphery tightly touch on cylinder inner wall, after avoiding piston ring long-time service, due to wearing, deforming,
Original elasticity is lost, causes piston ring and cylinder minute surface poorly sealed, leads to the problem of gas leak phenomenon.
Claims (2)
