Compress air to waste the sources of energy as the 2nd great power that electric energy is next to only inside the factory, it is the basic safeguard that factory production moves. The member that the mechanical equipment that because this serves as,reduces air production defends moving person its post responsibility is quite main.

But actually, the member that the operation of machine of pneumatics of big multitask factory runs a person is not come from entirely pursue this job professional or for a long time at this, often be temporarily perhaps can fly mechanism plane only, to basic compressor knowledge utterly ignorant.

One, the classification of compressor

QiAir Compressor

2, by exhaust pressure cent is different compressor

Pressure of exhaust of low-pressure compressor —— is less than 1.0MPa

Pressure of exhaust of —— of middling pressure compressor 1 ~ 10MPa

Pressure of exhaust of high-pressured compressor —— 10 ~ 100MPa

Pressure of exhaust of —— of extrahigh voltage compressor is more than 100MPa

3, V—3/20 explanation

V represents compressor form, 3— capacity produces tolerance namely, pressure of 20— delegate exhaust is highest can amount to 20MPa.

4, air and compress air

Airy composition: Nitrogen 78% , oxygen 21% , argon is enraged 0.93% , carbon dioxide 0.03% , neon is enraged 0.0018% , the toxic gas such as sulfur of other inert gase, moisture and dust, 2 oxidation, carbon monoxide.

Compressing air is the pressure that shows it is certain to have, had undertaken handling to the dust in air, moisture but second birth the sources of energy. Pressure, discharge, temperature is to compress airy 3 main index. Quantity of dry airy element is 28.96, the density when 0 ℃ , 760mmHg is 1.293g/m3.

5, measurement unit

Appearance of tally of particle of pressure watch, thermometer, dust, dew point.

6, substantival explanation

1. Dew point: Saturated air is in below constant pressure maintain vapor to divide what pressure reduces temperature to make below changeless circumstance to achieve saturated status. (written guarantee namely dew condensate separate out) , right now temperature calls dew point temperature.

2. Compression ratio: Of compressor exhaust pressure and the absolutely pressure that take energy of life than.

3. Absolutely pressure is to consider with complete vacuum or absolutely 0 values are compared, the environmental air that we live has the absolutely pressure of 0.1MPa.

4. Atmosphere force: Measure atmospheric pressure. Watch of pressure of absolutely pressure = shows pressure + atmosphere force.

5. Saturated air: Should do not have again much hydrosphere to be able to be accommodated when air is medium, produced airy saturation, any pressurization and the separate out that drop in temperature to all can cause condenser water.

6. Often press air: Stipulate pressure is 0.1MPa, the air that temperature issues for 36% condition for 20 ℃ , relative humidity is normal air.

7. Standard reference conditions: Stipulate inspiratory pressure is 0.1MPa, temperature offers the air of user system for what 0 ℃ condition falls.

7, care and maintenance

“ should accomplish when maintenance 3 must ” : Division of labor must be made clear before the task, in a planned way is responsible person, fill in serious; Undertake disassembling, the parts when installation works must be put in archives oil dish or on chasm board, be born is placed or must not put in disorder at will; After the job ends, must undertake be cleaned thoroughly and clearing to yard place, restore field former appearance.

1. Aircrew runs content of care and maintenance of 1000 ~ 1500Hrs:

(1) cleans an inhaler.

(2) examines the open case of various blowdown a powerful person, if pipeline is illogical, seasonable dredge conduit.

(3) checks each appearance to use in good condition.

2. Aircrew runs content of care and maintenance of 2000 ~ 2500Hrs:

(4) changes the inhaler filter core of damage.

(5) checks pressure and temperature reading;

(6) checks the air that unit may consist or oil to divulge a part to safeguard.

(The water that in water the examination on condenser may exist divulges 7) ,

(8) cleans condenser, clean the condenser of cold dry machine.

(9) changes oil and oily filter, should press on oily segregator fall when exceeding 1bar, change oily segregator. Examination grease segregator and blowdown pipeline are expedite circumstance, seasonable dredge pipeline.

(10) checks part of electric equipment automata, the freeboard that is like various pressure, super- low call the police circumstance.

(11) examination is electronic-controlled situation of close firm of column of the wiring inside ark, safe ground connection and safe guard are reliable circumstance.

(12) examination does not have hot second birth dry tower, thick filter, circumstance of the filter that remove oil.

3. Aircrew runs content of care and maintenance of 3500 ~ 4000Hrs:

(13) compressor part:

A) changes oily filter filter core, change lube.

B) examination is cleaned one-way force plunger of bedspring of a powerful person that break oil, necessary change.

C) cleans constant temperature a powerful person, if be necessary,can change appropriately.

D) examination wears away cooperate clearance, make good record, provide original record to heavy repair.

E) cleans oily condenser and aftercooler water to cover inside furring.

(14) operate supervisory system

The sensitivity of watch of A) various pressure, relief valve, school check.

Sensitivity of valve of B) each pipeline.

C) discovery already damaged truly change.

(15) cooling water system

A) cleans the furring inside cooling water box and contamination.

B) cleans water pump to import the soil inside screen pack.

C) checks the contamination inside cooling tower; Examination fan rotates water of cloth of circumstance, examination implement rotate circumstance, change or add grease.

8, fill in seriously all sorts of records
