Description
Technical field
The utility model belongs to air compressor field, specifically refers in a kind of integral type screw rod and presses air compressor.
Background technique
Air compressor is the basic product of the modernization of industry, and that often says electrically and in automation just has entirely pneumatic implication; And air compressor is just to provide the nucleus equipment that source of the gas power is pneumatic system, main body in dynamo-electric bleed air source device, it is the device mechanical energy of former dynamic (normally motor) being converted to gas pressure energy, is compressed-air actuated pressure generator.
Helical-lobe compressor---be rotary positive displacement compressor, two engage each other with the rotor of screw type gear wherein, make two rotor engagement place volumes from large to small, thus are discharged by gas compression.Screw compression assembly in screw air compressor, adopts latest model numerically control grinder inside to manufacture, and is engaged in line laser technology, guarantee that manufacturing tolerances is accurately incomparable.Its reliability and performance can guarantee that the running expense of compressor is always extremely low within the spreadable life.
Middle pressure---refer to: 1.57MPa (16kgf/cm
2)≤p<9.81MPa (100kgf/cm
2) pressure in scope.
Integral type---refer to that middle pressure Screw chiller inside is integrated with dry air system, filtration system and drainage system, their effect is interrelated and requisite important spare part.
Middle pressure air compressor plays one of crucial equipment in the field such as medicine, PET bottle blowing, water power, drilling well, military project.Middle pressure Screw chiller has both at home and abroad at present:
Air compressor is pressed in piston machine multistage compression;
Air compressor is pressed in screw rod and piston series connection;
The middle pressure air compressor of two-stage screw rod series connection;
The medium voltage network of screw air compressor+cooling driers+screw rod pressure-increasing machine three machine series connection.
The middle pressure air compressor of piston machine multistage compression is current most popular middle pressure air compressor.His shortcoming is that floor space is large, and noise is high, and vibration is large, and easily damaged parts is many, and standby redundancy is many, and maintenance maintenance workload is large, and unit is with piston ring scuffing, and exhaust pressure and the air displacement obvious energy consumption that declines increases.
Air compressor is pressed to be one-level screw compression and second piston compression series connection middle pressure air compressor integrally in screw rod and piston series connection.Mainly his one-level introduces helical-lobe compressor, decreases above-mentioned shortcoming to a certain extent, but his secondary still needs plunger booster, so above-mentioned shortcoming still also exists.
The middle pressure air compressor of two-stage screw rod series connection.Above-mentioned shortcoming is obviously improved, but he exists a fatal defect, because firsts and seconds is directly connected, the precipitation that the moisture in air will be a large amount of in compression process, separator can not transpiring moisture timely, causes emulsification after making compressor oil and water mixing.Have impact on bearing and the gear lubrication of unit, unit shortens working life greatly.So such unit can not reach very high pressure, can not long-time continual operation.This type is eliminated abroad, is used only at home on the mobile compressor of mine engineering.
The medium voltage network of screw air compressor+cooling driers+screw rod pressure-increasing machine three machine series connection is external middle pressure air compression system more novel at present.Cost is higher, and utilization amount is little.He is obtained for very large improvement above-mentioned shortcoming.But he is by the units connected in series of three difference in functionalitys, so his floor space is still very large, each unit needs mutually to debug coupling.Each Systematical control is relatively independent, higher to operation and maintenance difficulty.
The words (except the medium voltage network of screw air compressor+cooling driers+screw rod pressure-increasing machine three machine series connection) of the device of condensed water are not removed in the middle of above-mentioned all types of middle pressure air compressor, be certain to the wearing and tearing of quickening compressor and kill, the working life of machine is certain to shorten.Run in the environment of high humidity especially.
Current low pressure screw air compressor (0.6Mpa ~ 1.25Mpa) on the market instead of Piston Air Compressor completely.He is with excellent unfailing performance, vibrate little, noise is low, high the obtaining of easy to operate, few easy workout part, operational efficiency is used and favorable comment widely.But screw air compressor is used in middle pressure field and does not also promote widely and develop at present.Press air compressor to substitute in piston in screw rod and press air compressor, will be must trend.He has wide development space and the market demand.
