驅動(dòng)空氣壓力一般要為3-8bar(0.3-0.8MPa)， 當然不是這個(gè)壓力范圍內，同一臺增壓泵的增壓效果一致的，同一臺增壓泵的增壓比(驅動(dòng)活，塞與增壓活，塞的面積比)是固定的，驅動(dòng)氣壓3bar時(shí)與驅動(dòng)氣壓8bar時(shí)的輸出壓力是不一致。因此不要誤解為驅動(dòng)氣壓要求為3-8bar，就是指這個(gè)壓力區間內都能達到同一個(gè)壓力，因此選型時(shí)要根據現場(chǎng)的壓縮空氣的壓力選擇合適的增壓比，一般壓力要留有一定的余量。當壓力越接近泵的輸出壓力時(shí)，泵的頻率越慢，流量越小。

The driving air pressure is generally 3-8 bar (0.3-0.8 MPa), but of course, it is not within this pressure range. The boosting effect of the same booster pump is consistent. The boosting ratio of the same booster pump (driving pressure, plug to boost pressure, and plug area ratio) is fixed. The maximum output pressure at the driving air pressure of 3 bar is inconsistent with that at the driving air pressure of 8 bar. Therefore, do not misunderstand it as the driving air pressure requirement of 3-8 bar, which means that the same pressure can be reached within this pressure range. Therefore, when selecting, the appropriate pressure ratio should be selected based on the pressure of the compressed air on site, and generally, there should be a certain margin for pressure. As the pressure approaches the maximum output pressure of the pump, the frequency of the pump slows down and the flow rate decreases.

原理是大活，塞推動(dòng)小活，塞往復運動(dòng)實(shí)現增壓，隨著(zhù)壓力的出口端壓力的上升，大活，塞和小活，塞的兩端的力趨于平衡，故增壓泵運動(dòng)頻率下降、流量變小，當出口端的壓力是增壓泵的增壓比時(shí)，兩端力值平衡，增壓泵這時(shí)停止工作，流量為0，一旦一端氣壓下降，增壓泵會(huì )自動(dòng)工作，補齊壓力，具有自動(dòng)保壓、補壓功能。

The principle is that the large piston drives the small piston, and the piston moves back and forth to achieve pressure increase. As the pressure at the outlet increases, the forces at the two ends of the large piston, plug, and small piston tend to balance. Therefore, the frequency of the booster pump movement decreases and the flow rate decreases. When the pressure at the outlet is the boost ratio of the booster pump, the force values at both ends are balanced, and the booster pump stops working. The flow rate is 0. Once the pressure at one end drops, the booster pump will automatically work to make up for the pressure, Equipped with automatic pressure maintaining and replenishment functions.

耗氣量的要求，一般要求流量1m3/min左右，耗氣量不是一個(gè)固定值，當泵的負載越小時(shí)，泵的頻率越快，負載越大時(shí)，泵的頻率越慢，當達到泵的輸出壓力時(shí)，泵停止工作，不在耗氣。不建議選用220V電源的空氣壓縮機，220V的空壓機排氣量一般都較小，增壓泵不能發(fā)揮出正常效能。

The requirements for air consumption generally require a flow rate of about 1m3/min, and the air consumption is not a fixed value. The smaller the pump load, the faster the pump frequency. The larger the load, the slower the pump frequency. When the maximum output pressure of the pump is reached, the pump stops working and no longer consumes air. It is not recommended to use an air compressor with a 220V power supply. A 220V air compressor generally has a smaller displacement, and the booster pump cannot perform normally.
