空压机常用术语
Common terms of air compressor
•压力
Pressure
通常在压缩机铭牌上给出的排气压力为表压力,非绝对压力。
Generally, the discharge pressure given on the compressor name plate is gauge pressure, not absolute pressure.
常用压强单位:bar、MPa,空压机行业说的“公斤”是指“bar”,即1公斤就是指1bar,1MPa(兆帕)=1000kPa(千帕),1bar(巴)= 0.1MPa。
Commonly used pressure units: bar, MPa, air compressor industry said "kg" refers to "bar", that is, 1kg means 1bar, 1MPa (MPA) = 1000kPa (kPa), 1bar (bar) = 0.1MPa.
•容积流量
Volume flow
在国内又被称为排气量或铭牌流量,空压机单位时间内排出的气体容积,折算到进气状态,也就是吸气的容积,按国家标准,空压机的实际排气量为标称流量的±5%时均为合格。常用单位m³/min、L/s。
In China, it is also known as the exhaust volume or the rating plate flow. The gas volume discharged by the air compressor per unit time is converted to the air intake state, that is, the suction volume. According to the national standard, the actual air displacement of the air compressor is ± 5% of the nominal flow, which is qualified. Commonly used units are m 3 / min, L / s.
•气体含油量
Oil content of gas
单位体积的压缩空气中所含的油(包括油滴、悬浮粒子、油蒸气)的质量,通常我们所说的PPM为重量比值单位:PPM,1kg的百万分之一为毫克。
The mass of oil (including oil drops, suspended particles and oil vapor) contained in the unit volume of compressed air is usually ppm. The unit is ppm, and one millionth of 1kg is mg.
•压力露点
Pressure dew point
是指有一定压力的气体冷却到某一温度,其所含的未饱和水蒸气变成饱和水蒸气析出,此温度就是该气体的压力露点。大气露点,是指在标准大气压下型槽模具 一次性止血带 保定水处理设备 一次性止血带 保定空压机 北京真空泵,气体冷却到使所含的未饱和水蒸气变成饱和水蒸气析出的温度,在空压机行业中,露点表示的是气体的干燥程度。
It refers to that when a certain pressure gas cools to a certain temperature, the unsaturated water vapor contained in it becomes saturated water vapor, and the temperature is the pressure dew point of the gas. Atmospheric dew point refers to the temperature at which the gas is cooled to make the unsaturated water vapor contained in it become saturated water vapor under standard atmospheric pressure. In the air compressor industry, dew point represents the degree of gas drying
