Abstract
The utility model discloses a two-stage air compressor unit, which comprises a screw compressor (1), an intermediate cooler (2) and a piston compressor (3), wherein the screw compressor, the intermediate cooler and the piston compressor are sequentially connected and comprise air inlets and exhaust holes, the exhaust hole (12) of the screw compressor is communicated with the air inlet (21) of the intermediate cooler, and the exhaust hole (22) of the intermediate cooler is communicated with the air inlet (31) of the screw compressor. By the two-stage air compressor unit, the defect that the screw compressor or the piston compressor is singly utilized to compress air is overcome, and the two-stage air compressor unit has the advantages of large displacement, low energy consumption, high compression efficiency and excellent performance.
Description
Technical field
The utility model belongs to a kind of air compressor, particularly a kind of two-stage air compressor group.
Background technique
Generally between 0.7～1.3MPa, its compressed-air actuated pressure is lower for the exhaust pressure of helical-lobe compressor at present, if need the more pressurized air of high pressure, then will use piston compressor instead.And adopt separately piston compressor to prepare that pressurized air power consumption is large, efficient is low.
Summary of the invention
The purpose of this utility model provides a kind of two-stage air compressor group, it has overcome traditional independent use helical-lobe compressor or the compressed-air actuated shortcoming of piston compressor, have combined and instant, can comprehensive two kinds of compressor advantages, power consumption is little, compression efficiency is high, performance is good advantage.
This two-stage air compressor group comprises helical-lobe compressor, interstage cooler and the piston compressor that connects successively, helical-lobe compressor, interstage cooler and piston compressor include suction port and relief opening, the suction port UNICOM of the relief opening of helical-lobe compressor and interstage cooler, the suction port UNICOM of the relief opening of interstage cooler and piston compressor.Because the two-stage air compressor group that has adopted helical-lobe compressor and piston compressor to be combined into can produce high-pressure compressed air, has overcome the low shortcoming of independent use compressed air pressure that helical-lobe compressor produces.Adopt interstage cooler UNICOM's helical-lobe compressor and piston compressor, pressurize again so that enter piston compressor after the air cooling after the helical-lobe compressor compression, so that the compression efficiency of piston compressor is higher, use more separately the piston compressor power consumption less thus.This two-stage air compressor combines the advantage that the helical-lobe compressor air displacement is large, the piston compressor compressive force is large, and the air pressure shrinkage is high, performance is good.
Description of drawings
Fig. 1 is the structural representation of a kind of two-stage air compressor group of the utility model.
Embodiment
Now provide embodiment describing a kind of two-stage air compressor group of the present utility model in detail, specific as follows:
As shown in Figure 1, this two-stage air compressor group comprises helical-lobe compressor 1, interstage cooler 2 and the piston compressor 3 that connects successively.Helical-lobe compressor, interstage cooler and piston compressor include suction port and relief opening, the relief opening 12 of helical-lobe compressor and suction port 21 UNICOMs of interstage cooler, the relief opening 22 of interstage cooler and suction port 31 UNICOMs of piston compressor.
Working procedure is as follows:
Air from the suction port of helical-lobe compressor be inhaled into compressed in the helical-lobe compressor after, discharge and enter in the interstage cooler along the suction port of interstage cooler from the relief opening of helical-lobe compressor and cool.Gas after the cooling is discharged and is entered piston compressor through the suction port of piston compressor through the relief opening of interstage cooler and carries out secondary compression.The high-pressure compressed air that produces is at last discharged through the piston compressor relief opening.
Claims (1)
1. two-stage air compressor group is characterized in that: it comprises helical-lobe compressor (1), interstage cooler (2) and the piston compressor (3) that connects successively; Helical-lobe compressor, interstage cooler and piston compressor include suction port and relief opening, suction port (21) UNICOM of the relief opening of helical-lobe compressor (12) and interstage cooler, suction port (31) UNICOM of the relief opening of interstage cooler (22) and piston compressor.
