Abstract
The utility model relates to a piston-type compressor, comprising the piston of the electric compressor, a gas cylinder, a piston rod, a cross head, a connecting rod, a crank shaft, a shaft end sealing device, etc. A pressure ring and a screw are connected with the gas cylinder by the barrel type pipe of the shaft end sealing device or one end of the corrugated pipe. A fastener is connected with the piston rod on the other end of the corrugated pipe. The compressor has the characteristics that the compressor completely has no external leakage, the compressor is resistant to corrosion, the compressor does not pollute the environment, the compressor saves energy, etc.
Description
The utility model belongs to the machinery that gas is boosted.
The shaft end seal device of piston compressor all adopts filler to stop the leakage of gas between piston rod and cylinder in the cylinder at present.Although change the structure and the material of filler, in the time of also can't stoping leakage, the especially filler of gas to change, leakage rate is just bigger.For the leakage rate of compressing inflammable, explosive and poisonous and corrosive gas, require just tighter.But all there is leakage more or less in present sealing, all can not meet the demands.
The purpose of this utility model is at the axle head filler place of piston compressor, and a kind of seal arrangement of at all stopping gas leakage is provided.
A kind of piston compressor of the utility model is made up of piston 1, cylinder 2, piston rod 3, crosshead 4, connecting rod 5, bent axle 6, balancing volume 9, filler 8, air valve 10 and the shaft end seal device 7 of compressor.The cartridge type pipe of shaft end seal device 7 or an end of bellows 14 link to each other with cylinder 2 with pressure ring 11 and screw 12, and the other end of cartridge type pipe or bellows 14 links to each other with piston rod 3 with clip 13.
The bellows number of the bellows 14 of the shaft end seal device 7 that the utility model adopts has one at least, is preferably 2～6.Gas in the shaft end seal device 7 can communicate with the air inlet pipeline of certain one-level cylinder, also can communicate with the balancing volume 9 of cylinder, so can accomplish the leakage of at all having stopped gas.
Use the piston compressor of shaft end seal device, can reach does not on the one hand have external leakage fully, makes other component no longer such as piston rod be corroded and wear and tear on the other hand, improves the working life of parts such as piston rod greatly.Therefore the piston compressor that adopts shaft end seal device is more free from environmental pollution than having of not adopting, not etching apparatus, do not waste advantages such as gas, the operation cycle is long, efficient is high, maintenance expenses is low.
The piston compressor of shaft end seal device is housed, can be to acetylene gas, ethylene gas, oxygen, chlorine etc. inflammable, explosive and poisonous and corrosive gas compress, also can other any gas be compressed, improve the pressure of gas.
The material of cartridge type pipe or bellows is except that rubber, and also optional usefulness has certain elasticity and intensity, resists other material or the compound and combined material that deflect.
Two of the utility model drawings attacheds.
Fig. 1 is the piston compressor schematic representation that shaft end seal device is housed.
Fig. 2 is the schematic representation that shaft end seal device communicates with balancing volume.
Among the figure: 1-piston, 2-cylinder, 3-piston rod, 4-crosshead, 5-connecting rod, 6-bent axle, 7-shaft end seal device, 8-filler, 9-balancing volume, 10-air valve, 11-pressure ring, 12-screw, 13-clip, 14-cartridge type pipe or bellows.
Embodiment of the present utility model as shown in Figure 1.Driven by motor bent axle 6 rotates, and will rotatablely move by connecting rod 5, crosshead 4 becomes the to-and-fro motion of piston 1 and piston rod 3.When piston 1 by outer dead point during to the axle lateral movement, the lid side draught gas of cylinder 2, the axle side exhaust of cylinder 2, the gas of compression may bleed in bellows 14 from filler 8, the volume of shaft end seal device 7 constantly increases, and the gas in the bellows 14 communicates with the air inlet pipeline of certain one-level.When piston 1 by inner dead point to lid during lateral movement.The gas of compression may bleed in bellows 14 from filler 8, and the volume of shaft end seal device 7 constantly dwindles, and the gas in the bellows 14 still communicates with the air inlet pipeline of certain one-level.Shaft end seal device 7 as shown in Figure 2 communicates with balancing volume 9, when piston 1 to-and-fro motion.The gas that spills by piston ring all bleeds in bellows 14, and the two ends of bellows 14 link to each other with the base and the piston rod 3 of cylinder 2 respectively, and the gas that spills does not communicate with the external world.Only communicate or communicate, therefore can accomplish not have external leakage fully with balancing volume 9 with a certain level air inlet pipeline.So the external leakage of so just having stopped gas on the structure is just no longer befouling environment and etching apparatus also at all.
