Description
Technical field
The invention belongs to air compressor, relate to a kind of screw compression and Piston Compression tandem air compressor helical-lobe compressor and piston compressor series connection back composition.
Background technique
The piston unit volume of existing piston compressor is big, weight is big, piston machine piston linear velocity restriction (about 4M/S), low-pressure cylinder too expands, cylinder diameter has reached 1.5M, weight 13T, and during the Large Piston compressor operation, produce huge reciprocal inertia force and moment of inertia, must build large foundation during installation, large-sized workshop and lifting appliance cause investment to enlarge; Simultaneously air valve, piston ring and the filler of piston compressor all belong to easily damaged parts, and they have directly influenced the running rate of compressor, turn round under bad working environments, have reduced by three kinds of easily damaged parts working lifes, increase and clean the maintenance duration, increase operating cost and maintenance expenses; And large-scale unit fuel consumption is big, has increased cost of production.Because helical-lobe compressor do not have air inlet and exhaust valve, piston ring and filler three big easily damaged partss, thereby reliable operation, long service life need not shutdown maintenance; the running speed height, so unit is little, in light weight, gas is little; running is steady, few easy workout part, and manufacturing and maintenance are very convenient.Therefore, if can when low pressure stage, use helical-lobe compressor, use piston compressor during high pressure section, improve helical-lobe compressor single stage compression ratio, realize piston compressor I level, the compression of II level is finished by screw rod I level, certainly will reduce cost of investment, reduce maintenance expenses, improve the reliability of machine run.
Summary of the invention
The object of the present invention is to provide a kind of helical-lobe compressor and piston compressor to be cascaded, realize piston compressor I level, screw compression and Piston Compression tandem air compressor that the compression of II level is finished by screw rod I level.
The object of the present invention is achieved like this: it comprises helical-lobe compressor, piston compressor, motor, described motor is twin shaft output, helical-lobe compressor is connected with the twin shaft of motor respectively with piston compressor, filter cleaner is connected with the suction valve of helical-lobe compressor, and the outlet pipe of helical-lobe compressor is connected with the screw rod cooler, and is connected with moisture trap, knock out drum and piston compressor successively by pipeline.
The present invention is helical-lobe compressor and piston compressor cascaded structure, gas is behind filter cleaner dust removal dust under the normal pressure, enter helical-lobe compressor through suction valve, the pressurized air that mixes with oil enters separating barrel, after Oil-gas Separation, enter the screw rod cooler, cooling back pressurized gas enters knock out drum after air-water separation, clean gas enters piston machine and is pressurized to the required pressure of user, exports effective air displacement and pressure to the user.When the invention provides with equal pressure, body volume reduces relatively, and cost of investment reduces, and has reduced maintenance expenses simultaneously, improves the reliability of machine run.

Gas is behind filter cleaner dust removal dust under the normal pressure, enter helical-lobe compressor 3 through suction valve, make atmosphere gas be pressurized to 1MPa, enter screw rod cooler 5, the High Temperature Gas that helical-lobe compressor 3 is discharged is cooled off to normal temperature, cooling back pressurized gas enters knock out drum 6 after moisture trap separates, stabilizing gas reduces pressure pulsation, clean gas enters piston compressor 1, and the 1MPa pressurized gas that helical-lobe compressor 3 is discharged is pressurized to 80-100kg pressure, exports effective air displacement and pressure to the user.
Gas is behind filter cleaner dust removal dust under the normal pressure, enter helical-lobe compressor 3 and cooling and mixing through suction valve, make the normal pressure mixture be pressurized to 1MPa, compressed mixture enters separating barrel 4, the mixture that helical-lobe compressor 3 is discharged carries out the pressurized air separation, and the pressurized air after separating enters screw rod cooler 5.
Embodiment 3, and when the required pressure of user is 100kg when above, piston compressor 1 is more than the one-level, at this moment, connects piston compressor interstage cooler 7 between the piston compressor, and the high-temperature gas that the piston compressor upper level is discharged is cooled to normal temperature and uses for next stage.
When general required pressure was 100-150kg, piston compressor 1 was a secondary; When required pressure was 150-200kg, piston compressor 1 was three grades; Required pressure is 200kg when above, and piston compressor 1 is more than the level Four.
