在选购
气体增压泵时大家总会遇到一些疑惑或者说客户不知道怎么去选购，其实这个并不难。我们在选购气体增压泵（有氮气增压泵、氢气增压泵、氧气增压泵等等）时，要考虑多个方面，其中主要的方面有产气、稳定性及耗气等等。
When you choose and buy gas booster pumps, you will always encounter some doubts or customers do not know how to buy them. In fact, this is not difficult. When purchasing gas booster pump (including nitrogen booster pump, hydrogen booster pump, oxygen booster pump, etc.), we should consider many aspects, including gas production, stability and gas consumption.
1、产气：
1. Gas production:
作为气动装置的气体压缩机设备，它的主要作用是供气，可见产气量的重要性。而对于气源有些行业要求特别高，如热流道、激光切割等等，所以购买前需要确认好气体介质。
As the gas compressor equipment of pneumatic device, its main function is to supply gas, which shows the importance of gas production. Some industries have special requirements for gas sources, such as hot runner, laser cutting, etc., so it is necessary to confirm the gas medium before purchasing.
2、稳定性：
2. Stability:
稳定性对一台气动气体增压泵是有必要的，一台不具备稳定性的设备，能给我们的生产带来很大的困扰，给我们的企业带来一定的损失。提醒广大用户，现在国内很多气体增压泵生产厂商生产的产品达不到该要求，所以建议大家在选购时一定要慎重选择。
Stability is necessary for a pneumatic gas booster pump. A device without stability can cause great trouble to our production and bring certain losses to our enterprise. Remind users that the products produced by many domestic gas booster pump manufacturers can not meet the requirements, so it is suggested that you should be careful when purchasing.
3、耗气：
3. Gas consumption:
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，在所供气源压力不便的情况下，泵的往复次数决定于排出气体压力的大或小。当气源压力调高作空载排气时（如对被检大容积容器充气时）就是泵耗气量大的时候。
The air consumption is mainly determined by the reciprocating times per minute of the driving cylinder piston of the booster pump. In the case of inconvenient air supply pressure, the reciprocating times of the pump depend on the large or small exhaust gas pressure. When the air supply pressure is adjusted to high for no-load exhaust (such as filling the container with large volume to be inspected), it is the time when the pump consumption is large.
随着被试容器内的气压逐渐升高，泵的往复速度也逐渐减慢，直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。
As the air pressure in the container under test gradually increases, the reciprocating speed of the pump also gradually slows down, until the driving gas pressure is proportional to the exhaust gas pressure, the pump stops working, and the air consumption is equal to zero.
The gas booster pump should be purchased from three aspects. Do you understand? Of course, the price is also in the key consideration. You should go to the market in advance to understand the market price of the equipment. Come to our website for more matters http://www.sdjingtuo.com Ask about it!
