Abstract
The utility model is related to compressor field, and solving must use piston bad sealing cylinder in the prior art, and piston ring can also cause the problem of the consumption of lubricating oil, and the utility model provides a kind of oil-free refrigeration compressor, includes cylinder（1）Be arranged on cylinder（1）Interior piston（2）, the cylinder（1）Inside it is additionally provided with compressed bag（3）, the compressed bag（3）By pressing plate（4）It is fixed on piston（2）On.
Description
Technical field
The utility model is related to compressor field, refers in particular to a kind of oil-free refrigeration compressor.
Background technology
Existing compressor includes cylinder, is arranged on intake valve and air bleeding valve on cylinder, is arranged on cylinder bottom
Piston, drives the piston rod and bent axle of piston movement.
The piston ring of piston is used for the swept volume of sealing cylinder, between preventing compressed gas between piston and cylinder wall
Gap is leaked, i.e. leakage path of the block fluid between the piston and static cylinder wall of motion.But piston ring is with piston
During motion, because motion is done work, not only temperature is raised, and can consume lubricating oil, can influence the effect of compressor, particularly right
The refrigeration of the compressor in terms of refrigeration produces influence.
The patent of invention of Patent No. 201180074681.0, discloses a kind of compressor, compressor with closed container
The front opening of the refrigerant discharge leader of connection installs sealing bolt.Refrigerant ingress pipe have sealing container side component pipe portion,
The expansion tube department of front opening side is located at than component pipe portion expander, sealing bolt has flange part, protruded from flange part and inserts system
Cryogen discharge insertion section inside the Pass, insertion section is the step being made up of the large-diameter portion of flange part side and the minor diameter part of front
Shape, the external diameter of minor diameter part be set to than in expansion tube department through size that small and than component pipe portion internal diameter is big.The utility model can
The generation of unfavorable condition caused by avoiding being damaged due to the front opening of the pipe arrangement that sealing bolt is connected with closed container.But should
Utility model patent can not solve that piston ring ability sealing cylinder must be used in the prior art, simultaneously because using piston ring
Cause the problem of lubrication oil consumption.
The content of the invention
Goal of the invention of the present utility model is：In order to solve that piston bad sealing cylinder must be used in the prior art, and
The problem of lubrication oil consumption can be also caused using piston ring, the utility model provides a kind of oil-free refrigeration compressor.
A kind of oil-free refrigeration compressor, includes cylinder and is arranged on the piston of cylinder bottom, and compression is provided with cylinder
Bag, the bottom of compressed bag is fixed on piston by pressing plate.
Because compressor of the prior art could must be sealed using piston ring to cylinder, the use meeting of piston ring
Consumption lubricating oil, the effect to compressor impacts, particularly on refrigeration in terms of the refrigeration of compressor produce influence.
The utility model sets compressed bag in cylinder, and due to the bottom pressing plate of compressed bag is fixed on piston, compressed bag is opened
Mouthful direction upwards, the bottom of compressed bag is fixed with pressing plate, makes very close to each other between pressing plate and compressed bag, is reached and is not needed piston ring
Just salable cylinder and the effect of lubricating oil is not consumed.And because the utility model substituted for original piston using compressed bag
Ring, gas compressed will not receive the pollution of lubricating oil, have more preferable guarantee to the gas purity after compression.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model intake process.
Fig. 2 is the schematic diagram of the utility model compression process.
Fig. 3 is the schematic diagram of the utility model exhaust process.
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.
A kind of oil-free refrigeration compressor, includes cylinder 1 and is arranged on the piston 2 of the bottom of cylinder 1, is also set up in cylinder 1
There is compressed bag 3, the bottom pressing plate 4 of compressed bag 3 is fixed on the piston 2.
Described compressed bag material be can deformation material, preferably ductile metal.
Preferred compressed bag 3 is ripple bag 5, and ripple bag 5 refers to the compressed bag 3 that foldable ripple is set in compressed bag 3,
The ripple bag 5 can be folded or compressed along ripple direction.
When use, intake process as shown in Figure 1, closes air bleeding valve 6, opens intake valve 7, in bent axle 8 by living
Stopper rod 9 is moved with piston 2, and piston 2 is moved from top dead centre 10 to lower dead center 11, and the volume of ripple bag 5 gradually increases, and gas leads to
Cross intake valve 7 and be inhaled into cylinder 1, when piston 2 moves to lower dead center 11, intake process is completed.
Compression process as shown in Figure 2, closes intake valve 7, intake valve 7 and air bleeding valve 6 is in closed mode, bent axle
8 from lower dead center 11 to top dead centre 10 with piston 2 by piston rod 9 when being moved, and ripple bag 3 is compressed, and volume constantly reduces, ripple
Gas in line bag 3 is compressed, and the pressure and temperature of gas is raised simultaneously.
After the completion of the process of compressed gas, exhaust process as shown in Figure 3, open air bleeding valve 6, intake valve 7 still in
Closed mode, bent axle 8 is moved by piston rod 9 with piston 2, and piston 2 is moved from lower dead center 11 to top dead centre 10, by compressed gas
Body with the motion of piston 2, through the discharge cylinder 1 of air bleeding valve 6 outside, when piston 2 moves to top dead centre 10, exhaust process knot
Beam, air bleeding valve 6 is closed.
