Description
Technical field
The utility model relates to a kind of pneumatic machinery equipment technical field, particularly relates to a kind of air compressor.
Background technique
air compressorbe the basic product of the modernization of industry, that often says electrically and in automation just has entirely pneumatic implication; And air compressor to be just to provide source of the gas power be main body in the dynamo-electric bleed air source device of nucleus equipment of pneumatic system, it be the mechanical energy of former dynamic (normally motor) is converted to gas pressure can
device, be compressed-air actuated pressure generator.China
air compressorthe market scale of industry is the speedup growth of more than 8%, and 2010-2011 annual growth has even exceeded 28%, and market scale expansion rapidly.But on the market that scale is so huge, a very long time in past grasps most market by overseas-funded enterprise.In 2009 years, China's air compressor industry has nearly 400 of manufacturing enterprise, and wherein interior-capital-enterprise's quantity is close to 90%, and enforcement sale gross income is about 6,000,000,000 yuan, accounts for 40% of the whole industry; Overseas-funded enterprise's quantity is close to 10%, and enforcement sale gross income is about 9,000,000,000 yuan, accounts for 60% of the whole industry.
During compressor operating, air is through self-cleaning type
air filterbe inhaled into, by PLC automatic cleaning strainer, air enters one stage of compression after automatically regulating through entry guide vane, gas temperature after one stage of compression is higher, then enter interstage cooler and carry out cooling that (water is walked in pipe, make leave with rage outside pipe, the water flow of intercooler requires as 110m/h) enter two-stage compression system afterwards, pour in compression chamber for avoiding the gas in system and (avoid starting with pressure) and be provided with one at the exhaust duct of compressor hanging complete opening type safety check, the gas that compressor is discharged is pushed safety check open and is entered exhaust silencer, then one-level aftercooler is entered, secondary aftercooler, enter exhaust main pipeline again.By
motordirect driving compressor machine, makes bent axle produce rotary motion, and drivening rod makes piston produce to-and-fro motion, causes volume of cylinder to change.Due to the change of inner pressure of air cylinder; air is made to enter cylinder through air-strainer (silencing apparatus) by suction valve; in compression stroke; due to reducing of volume of cylinder; pressurized air is through the effect of outlet valve; through outlet pipe, one-way valve (safety check) enters gas holder, is controlled and autostop by pressure switch when exhaust pressure reaches rated pressure 0.7MPa.When reservoir pressure is down to 0.5--0.6MPa, pressure switch connects startup automatically.
Volume flow to be otherwise known as air displacement or nameplate flow in China.Popular says under required exhaust pressure, the gas volume of discharging in the air compressor unit time, conversion to air-suction state, also namely the pressure of inspiration(Pi) at first order air inlet tube place and inhalation temperature and humidity time volumetric values.Namely air-breathing
volume.By NBS, the actual exhaust air amount of air compressor be rated flow ± 5% time be qualified.If rotating speed does not change, pressure change does not affect air displacement in theory, specifically, affects volume flow, does not affect mass flow rate.Because we are general, said air displacement refers to charge flow rate, thus be do not have vicissitudinous.Piston
air compressoralthough, for manufacturing enterprise,
screw air compressortechnology and the fund threshold of main frame and the production of crucial controlling component are very high, produce and are not easy very much.But for user, from the analysis of upper table, at twin-screw
air compressorapplicable scope in, with corresponding piston type
air compressorrelatively, unique shortcoming of twin-screw is that acquisition cost is high, but this from the low user cost of twin-screw and can be made up the long-life completely, and in fact, acquisition cost only accounts for the very little ratio of whole cost.In order to run with enabling air compressor normal reliable, ensure the working life of unit, must formulate detailed maintenance plan, execution is determined people's operation, periodic maintenance, is made regular check on maintenance, makes air-compressor set keep clean, without oil, without dirt.Air compressor often runs about 2000h, for removing heat-delivery surface dust, the cooler on blower tray need be purged port lid and opening, purging with drifting dust air gun to cooler, until heat-delivery surface dust purges clean.If still heat-delivery surface dirt is serious, is difficult to purge clean, cooler can be unloaded, pour out the oil in cooler and four are imported and exported and close to prevent dirt from entering, then blow down the dust on two sides with pressurized air or rinse with water, finally drying up the water stain of surface.Reinstall.Air compressor long-time running can cause equipment to be blocked by incrustation scale, will make efficiency reduction, energy consumption increases, the lost of life.If incrustation scale can not be removed in time, device maintenance will be faced, shut down or scrap the danger of replacing.
Current existing air compressor in use there will be overheated situation, significantly can reduce the working life of compressor.
