消费者选购空气压缩机时主要考虑以下几个方面：
Consumers mainly consider the following aspects when purchasing Air Compressors:
一、应考虑排气压力的高低和排气量大小。一般用途空气动力用压缩机排气压力为0.7MPa、0.8MPa。如果用户所用的排气压力达0.8MPa至1.2MPa，可采用双级空气压缩机。排气量是空压机的主要参数之一，选择空气压缩机的排气量和所需扭王块模具 高铁遮板模具  保定室内设计培训 保定平面设计培训的气流量相匹配，并应留有10％的余量。
1、 The exhaust pressure and volume shall be considered. The discharge pressure of general-purpose aerodynamic compressor is 0.7MPa and 0.8MPa. If the exhaust pressure used by the user reaches 0.8MPa to 1.2MPa, a two-stage air compressor can be used. The exhaust volume is one of the main parameters of the air compressor. Select the exhaust volume of the air compressor to match the required air flow, and leave a 10% margin.
二、要考虑压缩空气质量。一般空气压缩机产生的压缩空气均含有一定量润滑油，并有一定量的水气，当使用场合是禁油和禁水时，不仅要关注压缩机选型，还要关注增加必要附属装置。
2、 Compressed air quality should be considered. Generally, the compressed air produced by the air compressor contains a certain amount of lubricating oil and a certain amount of water gas. When the use occasion is oil and water prohibition, we should not only pay attention to the selection of the compressor, but also pay attention to the addition of necessary auxiliary devices.
