3) low exhaust temperature, piston compressor adopts 3 grades of compressions, and pressure ratios at different levels are not more than 2.5, although be under hot and humid environment, delivery temperature is no more than 160 ℃;
4) large-tonnage basic part, piston compressor adopts large piston force basic part, and the compressor multiple piston load is less than 80% of basic part design piston force.
2, Economy:
1) adopt fat pipe low-loss He Erbige air valve;
2) piston ring and filler adopt and fill polytetrafluoro and engineering plastics PEEK, a small amount of oiling, the merit of reducing friction to greatest extent;
3) efficient single screw compressor and large capacity deaerator reduce the power consumption of helical-lobe compressor.
3, monitoring and controlling system performance: compressor adopts transmitter, Siemens PLC C and touch screen to carry out monitoring and controlling to compressor operation parameters, the scene can be carried out the start/stop of compressor machine and be controlled, but data teletransmission output possesses the control room stopping function;
4, oil removing, dedusting and the characteristic that dewaters: adopt 3 grades of high efficiency filters after pressurized gas are cooling through aftercooler, after the ultrafiltration dry decontamination, can make the gas oil content of discharge less than 1mg/m
3, the dust particle diameter is less than 1 μ m, and dew point is lower than-55 ℃;
5, drainage characteristic: compressor is provided with blow down tank, and separators at different levels blow down to separate in tank and store, and gas is from jar top relief opening discharge, and exhaust port is provided with silencing apparatus to reduce exhaust sound, blow down tank design pressure 0.7MPa;
6, Security: adopt the process control that mechanical and electric multilayer is protected, complete reliable automation control system is perfect and use for reference domestic and international high pressure compressor advanced technology design, guarantee the compressor safe and reliable operation.
Compared with prior art, the beneficial effects of the utility model are embodied in: first order compression is pressed single screw compressor (exhaust pressure is greater than 1.6MPa) in adopting, thereby reduced piston compressor sum of series compression ratio, the reduction of piston force, machine volume and weight have been alleviated, thereby reduced delivery temperature, improved operating conditions, improved life of product and reliability.

Fig. 2 is single screw compressor main machine structure schematic diagram;
Fig. 3 is the structural representation of piston compressor.
Embodiment
The utility model is achieved in that
As Fig. 1~shown in Figure 3, a kind of high pressure list screw-plunger compound compressor unit, press single screw compressor 2 as the one-level compression in employing, middle pressure single screw compressor 2 has the special engagement pair molded line of high-performance and interior compression ratio, and the single stage compression exhaust pressure reaches 1.8 MPa.To 1.8MPa, then adopting three grades of piston compressors 1 to be pressurized to 40MPa when air compressing, is both the overall skid-mounted formula, specified air displacement 20m/min, maximum exhaust pressure 40MPa.Unit power is dual-motor, and three grades of piston compressors 1 of middle pressure single screw compressor 2 and high pressure are divided on two motors 3, with motor 3 be all that elasticity is direct-connected, motor 3 utilizes soft start.In system, the type of cooling of each cooler and unit is Water cooling type.Air is through equipment such as single screw compressor 2, gas-liquid separator 4, piston compressor 1, oil removal filter and exsiccators 5, uses the gas requirement with what reach the user.Unit is arranged on same underframe, and global design compact structure, volume are little, lightweight.Compressor bank is controlled by automatic control system 6.
