1、气体流量。选择一台增压器需要考量的是产气，也就是泵体出气口更大流量。有些客户对气的质量以及流量需求较高，在这个问题上还可以根据企业的这种前提和标准而定。
1. Gas flow. When selecting a supercharger, the first thing to consider is gas production, that is, greater flow at the air outlet of the pump body. Some customers have high demand for gas quality and flow, which can also be determined according to the premise and standard of the enterprise.
2、耗气。耗气量主要是由增压泵的驱动缸活塞的每分钟的往复次数所决定的，在所供气源压力不利的情况下，泵的往复次数取决于排出气体压力的大或小。随着被试容器内的气压渐渐升高，泵的往复速度也逐步减慢，直到驱动气气压与排气气压成比例平衡后，泵就停止工作，耗气量就等于零。
2. Gas consumption. The air consumption is mainly determined by the reciprocating times per minute of the driving cylinder piston of the booster pump. When the pressure of the air supply source is unfavorable, the reciprocating times of the pump depend on the discharge gas pressure. As the air pressure in the tested container gradually increases, the reciprocating speed of the pump gradually slows down until the driving air pressure is proportional to the exhaust air pressure, the pump stops working and the air consumption is equal to zero.
3、价位。现在国内的市场里面的状况是，国内设备相对便宜，国外的设备相对昂贵。其实在这一块说真的不是一个很主要的因素，需看产气及其的显示，这些要素更应该被考量。
3. Price. Now the situation in the domestic market is that domestic brand equipment is relatively cheap and foreign equipment is relatively expensive. In fact, the price is really not a very important factor. It depends on the display of gas production and energy saving. These factors should be considered.
4、售后服务。售后服务这也是一个考虑因素，选择一个有知名度的生产厂家在售后服务这块依旧能让广大消费者安心。这个要素现在也愈来愈被注重，所以，选择气体增压器，必然要认准厂家。
4. After sales service. After sales service is also a consideration. Choosing a manufacturer with brand awareness can still reassure consumers in the area of after-sales service. This element is also paid more and more attention now. Therefore, when choosing the brand of gas supercharger, we must recognize the brand manufacturer.
