氣體增壓泵該如何選型

一、氣體增壓泵是氣體,我們就在氣體增壓器中選;增壓介質是液體,我們就在氣動液體增壓泵中選。
First, the gas booster pump is gas, we will choose in the gas supercharger; booster medium is liquid, we will choose in the pneumatic liquid booster pump.
二、根據系統所需壓力初步確定泵的型號。根據計算出來的增壓比,在相應類型的泵表中選擇型號。注意,通常我們會選擇增壓比略高于計算值的泵,以確保我們的泵在通常情況下都能輸出系統所需壓力。
Two, according to the required pressure of the system to determine the pump type. According to the calculated booster ratio, choose the type in the corresponding type of pump table. Note that we usually choose slightly higher than the calculated value of the booster pump, the pump to ensure that we can output the required pressure system under normal conditions.

三、核算泵的流量是否滿足系統要求。當我們根據泵的出口壓力初步選擇了泵的型號后,我們需要核算改泵的流量是否滿足要求。
Three. Check whether the flow of the pump meets the requirements of the system. When we select the pump model according to the outlet pressure of the pump, we need to calculate whether the flow of the pump meets the requirements.
泵的流量計算方法是這樣的:每沖程的排量×每分鐘的動作頻率(一般以40計)。比如,氣動液體增壓泵10-4000W003,我們在泵表中查到它每沖程的排量是42.50ml,那么它的流量Q=q×n=42.50ml×40=1700ml/min=1.7L/min。將這個流量與系統需要的流量比較,看是否滿足要求。
The method of calculating the flow of a pump is this: the displacement per stroke is equal to the action frequency per minute (usually 40). For example, pneumatic liquid booster pump 10-4000W003, we find in the pump table that its displacement per stroke is 42.50ml, then its flow rate Q=q x n=42.50ml x 40=1700ml/min=1.7L/min. Compare the flow with the flow needed by the system to see if it meets the requirements.
