为什么启动空气增压泵有时候会出口压力降低?这个问题网

为什么启动空气增压泵有时候会出口压力降低?这个问题网上很多人在讨论,大家对空气增压泵的了解没有透,也可以是说不懂空气增压泵。问题都已讲清楚单试关闭出口时空气增压泵能憋起压力,说明空气增压泵没问题,那为什么打不起压呢,反而启动后出口压力降了?
Why does the outlet pressure of the starting air booster pump sometimes decrease? Many people are discussing this issue online. We don't know enough about the air booster pump. It can also be said that we don't understand the air booster pump. The problem has been clearly explained. When the outlet is closed in a single test, the air booster pump can hold up the pressure, which means that the air booster pump has no problem. Why can't it start up, but the outlet pressure drops after startup?
启动空气增压泵时发现出口压力降低的问题在于:空气增压泵是一种气动增压泵,也就是气体驱动的增压泵,增压过程中是需要消耗压缩空气的。
When starting the air booster pump, it is found that the problem of reducing the outlet pressure is that the air booster pump is a pneumatic booster pump, that is, a gas driven booster pump, which needs to consume compressed air in the pressurization process.
举例:假如压缩机干气密封需要的压缩空气消耗量为0.6立方/分钟,客户空压机的排量为1立方/分钟,空气增压泵不开启时,压力能维持在0.6MPa(650kpa),当空气增压泵开启后,空气增压泵需要压缩空气做为动力。这就造成了压缩空气消耗量比空气增压泵启动前增大了,自然压力反而变低。
For example, if the compressed air consumption required for the dry gas seal of the compressor is 0.6 m3 / min and the displacement of the customer's air compressor is 1 m3 / min, the pressure can be maintained at 0.6MPa (650kpa) when the air booster pump is not started. When the air booster pump is started, the air booster pump needs compressed air as power. This causes the compressed air consumption to increase compared with that before the start of the air booster pump, and the natural pressure becomes lower.
所以大家在对空气增压泵选型时,务必计算好流量大小。
Therefore, when selecting the type of air booster pump, we must calculate the flow.
