Pneumatics machine summarizes:
Pneumatics machine: Be reduce gas the machine that increase aeriform pressure or transports gas.
Action: Blow gas to produce gas, refrigeration and motivation of detached, drive, synthesis and polymerization, gas to carry etc.
Use a field: Like all of electron, car, steely, plastic, mould, hardware, medicine, chemical industry, food, beverage, home, presswork, phreatic water, fire control, glass, environmental protection, biology, the sources of energy, pottery and porcelain, cement, mine, power plant, petrifaction, shipping, war industry… etc.
Pneumatics machine is commonly used term:
Pressure intensity of pressure: Discharge baric force to be meter pressure in what give out on compressor nameplate normally, be not absolutely pressure.
Unit of commonly used intensity of pressure: Bar, MPa, pneumatics machine industry says ” kilogram ” it is to point to ” Bar ” , namely 1 kilogram points to 1bar namely, 1MPa (million handkerchief) =1000kPa (1000 handkerchief) , 1bar (cling to) = 0.1MPa.
Cubage discharge: Be called again in home capacity or nameplate discharge, the aeriform cubage of the eduction inside time of pneumatics airplane unit, convert arrives the condition that take energy of life, namely inspiratory cubage, press national level, the actual capacity of pneumatics machine is nominal the ± of discharge 5% when all be qualification.
Commonly used unit: M3/min, L/s.
Aeriform oil content: The oil that the compression of unit volume contains in air (include particle of oily drop, in suspension, oily steam) quality, the PPM that normally we say is weight ratio unit: PPM, of 1kg 1/1000000 for milligram.
Pressure dew point: It is to show the gas that has constant pressure cools some temperature, the not saturated vapor that its contain turns saturated vapor into separate out, this temperature is the pressure dew point of this gas. Atmosphere dew point, it is to show in the standard atmosphere falls, aeriform refrigeration turns saturated vapor into the temperature of separate out to the not saturated vapor that makes contain, in pneumatics machine industry, dew point is denotive the dry degree that is gas.
Than power: It is the power that shows place of discharge of compressor unit volume is used up. It is the main index that the evaluation reduces functional effect. Pneumatics machine compares power unit: KW/m3.
According to standard GB19153-2009 ” cubage type air compresses value of functional effect demarcate to reach can effect grade ” regulation, cent of grade of pneumatics function effect is 4 class:
1 class (best class) , 2 class (energy-saving evaluation is worth) , T class (target can effect demarcate is worth) , 3 class (can effect demarcate is worth) . Among them 1 class can effect is highest, prohibit produce and be being sold under 3 class. T class is a target can effect demarcate grade, its can effect excel 3 class, already replaced 3 form at rising on December 1, 2013 can effect value.
1 class achieves international advanced level, the most energy-saving, bad news can lowest;
2 class are more energy-saving;
3 class cost can be high, it is market admittance index.
