  刚入门的人可能会对空压机行业的很多术语感到困惑,下面小编就给大家介绍一下一些常用的词汇:

  New entrants may be confused by many terms in the air compressor industry. The following edition will introduce some commonly used words to you:
  螺杆式空气压缩机
  Screw Air Compressor
  空压机全称空压机;根据双螺杆(也称为阴阳转子)气体体积变化的旋转机器的工作原理设计的,它可以通过内部自然空气吸入一些流程完成工作,最终的排放,以满足压力要求的紧缩空气,这台机器被称为螺杆式空气紧缩机。
  Air compressor is called air compressor; according to the working principle of twin-screw (also known as Yinyang rotor) rotating machine with variable gas volume, it can complete the work by inhaling some internal natural air and eventually discharging compressed air to meet the pressure requirements. This machine is called screw air compressor.
  空气压缩机工作压力
  Working Pressure of Air Compressor
  压力单位的表达很多,这里主要介绍螺杆空压机常用的压力单位;
  There are many expressions of pressure units. Here, the commonly used pressure units of screw air compressor are mainly introduced.
  (1)工作压力大,国内用户常称排气压力大。工作压力是空压机的最高压力;
  (1) Work pressure is high, domestic users often say that the exhaust pressure is high. The working pressure is the highest pressure of the air compressor.
  (2)常用工作压力单位:bar或Mpa, 1 bar = 0.1mpa;
  (2) Commonly used work pressure units: bar or Mpa, 1 bar = 0.1 mpa;
  (3)常见时,用户通常将压力单位称为:Kg (Kg), 1bar = 1kg。
  (3) Usually, users call pressure units Kg (Kg), 1bar = 1kg.
  空气压缩机容积流量
  Volumetric Flow of Air Compressor
  流量大,国内用户常说排量大。容积流量是指空气压缩机在要求的排气压力下,单位时间内转换为进气状态的气体排放量。
  Large flow, domestic users often say that large displacement. Volumetric flow refers to the amount of gas discharged by an air compressor that is converted into an intake state per unit time under the required exhaust pressure.
  (2)容积流量单位:m3/min(立方/分)或L/ min(升/分),1m3(立方)= 1000L(升);
  (2) Volume flow units: m3/min (cubic/minute) or L/min (liter/minute), 1m3 (cubic) = 1000L (liter);
  (3)常用、常用流量单位为:m3/min(立方/分);
  (3) The commonly used and commonly used flow units are m3/min (cubic/minute);
  容积流在我国也称为置换流或铭牌流。
  Volume flow is also called displacement flow or nameplate flow in China.
  空气压缩机功率
  Air compressor power
  (1)一般情况下,空压机功率是指匹配的驱动电机或柴油机铭牌功率;
  (1) In general, the power of air compressor refers to the matching power of driving motor or diesel engine nameplate;
  功率单位为:KW (KW)或HP (HP/HP), 1KW≈1.333HP。
  The unit of power is KW (KW) or HP (HP/HP), 1KW 1.333HP.

  A.体积流量:
  Volume flow:
  容积流在中国也被称为位移流或铭牌流。
  Volumetric flow is also called displacement flow or nameplate flow in China.
  浅讲在排气压力的要求下,空压机机组时间将废气量转换为进气状态,即第一层进气接收在吸气压力和吸气温湿度容积值下。单位是m3/min。
  Simply speaking, under the requirement of exhaust pressure, the air compressor unit time will convert the exhaust gas into the intake state, that is, the first intake receives under the suction pressure and the volume value of the suction temperature and humidity. The unit is m3/min.
  b .排气压力:
  B. Exhaust pressure:
  平减指数行业的压力就是我们所说的高中压力。在大气压为零时测得的压力称为表压。绝对真空中的压力为零称为绝对压力。通常压缩机铭牌上给出的排气压力为表压。单位是MPa或bar。
  Reducing the pressure in the index industry is what we call high school pressure. The pressure measured at zero atmospheric pressure is called gauge pressure. Absolute pressure is called absolute pressure when the pressure in absolute vacuum is zero. Usually the exhaust pressure given on the nameplate of the compressor is gauge pressure. The unit is MPa or bar.
  C.气油含量:
  C. Gas and oil content:
  压缩空气中每单位体积所含的油(包括油滴、悬浮颗粒和油蒸气)的质量,换算为规定大气条件下的绝对压力0.1mpa,温度20℃,相对湿度65%,单位mg/m3。
  The quality of oil (including oil droplets, suspended particles and oil vapor) per unit volume in compressed air is converted to absolute pressure of 0.1 mpa, temperature of 20 C, relative humidity of 65% and unit mg/m3 under specified atmospheric conditions.
  D。P点:
  D. P:
  一种符号,表示混合物中痕量物质的量,单位为百万分之一或百万分之一(按重量和体积计算的PPMw和PPMv)。一般来说,我们称之为PPM的是重量比。(1千克的百万分之一是毫克)
  A symbol representing the amount of trace substances in a mixture in units of one millionth or one millionth (PPMw and PPMV by weight and volume). Generally speaking, what we call PPM is the weight ratio. (One millionth of a kilogram is milligram)
  参数1PPMw=1.2mg/m3(PA= 0.1mpa, t=20℃,phi =65%)
  Parameter 1PPMw = 1.2mg/m3 (PA = 0.1mpa, t = 20 C, phi = 65%)
  E.露点温度
  E. Dew Point Temperature
  湿空气在等压下冷却的温度,使空气中的不饱和蒸汽变为饱和蒸汽,或当空气的温度下降到露点时,空气中的不饱和蒸汽达到饱和。
  The temperature at which the wet air is cooled under constant pressure changes the unsaturated vapor in the air into saturated vapor, or when the temperature of the air drops to dew point, the unsaturated vapor in the air reaches saturation.
  压缩机容积流量与气动元件耗气量的异同
  Compressor Volume Flow and Air Consumption of Pneumatic Components
  压缩机容积流量为自由空气流量,气动元件耗气量为压缩状态下空气流量。
  Compressor volume flow is free air flow, pneumatic components consumption is compressed air flow.
  转换公式为Q从= Q压力*和损失m3/min
  The conversion formula is Q from= Q pressure* and loss m3/min.
  =P(恒压)/P吸入(恒压)=(P(名义压力)+1.033)/1.033
  = P(Constant Pressure)/P Inhalation(Constant Pressure)=(P(Nominal Pressure)+1.033)/1.033
  =(P 'row(压力表压力)+0.1013)/0.1013
  = (P'row(pressure gauge)+0.1013)/0.1013
  其中P排(表压)-单位kg/cm2
  Among them, P row (gauge pressure) - unit kg/cm 2
  P '列(表压)-单位MPa
  P'column (gauge pressure) - unit MPa
