為什么啟動空氣增壓泵有時候會出口壓力降低?這個問題網上很多人在討論,大家對空氣增壓泵的了解沒有透,也可以是說不懂空氣增壓泵。問題都已講清楚單試關閉出口時空氣增壓泵能憋起壓力,說明空氣增壓泵沒問題,那為什么打不起壓呢,反而啟動后出口壓力降了?
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?
啟動空氣增壓泵時發現出口壓力降低的問題在于:空氣增壓泵是一種氣動增壓泵,也就是氣體驅動的增壓泵,增壓過程中是需要消耗壓縮空氣的。
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.
舉例:假如壓縮機干氣密封需要的壓縮空氣消耗量為0.6立方/分鐘,客戶空壓機的排量為1立方/分鐘,空氣增壓泵不開啟時,壓力能維持在0.6MPa(650kpa),當空氣增壓泵開啟后,空氣增壓泵需要壓縮空氣做為動力。這就造成了壓縮空氣消耗量比空氣增壓泵啟動前增大了,自然壓力反而變低。
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.
所以大家在對空氣增壓泵選型時,務必計算好流量大小。
Therefore, when selecting the type of air booster pump, we must calculate the flow.
