增壓泵原理是利用大面積活塞的低氣壓產(chǎn)生小面積活塞的高液壓。工業(yè)領(lǐng)域用于機床卡盤(pán)的卡緊，蓄能器充氣，高壓瓶充氣，降低壓氣體轉換成高壓氣體等。那么
氣液增壓泵大概是怎樣工作的？
The principle of booster pump is to use the low air pressure of large area piston to generate the high hydraulic pressure of small area piston. In the industrial field, it is used for clamping the chuck of machine tools, charging the accumulator, charging the high-pressure bottle, and converting the reduced pressure gas into high-pressure gas. How does the gas-liquid booster pump work?
先將增壓泵內充滿(mǎn)液體，然后啟動(dòng)離心泵，葉輪快速轉動(dòng)，葉輪的葉片驅使液體轉動(dòng)，液體轉動(dòng)時(shí)依靠慣性向葉輪外緣流去，同時(shí)葉輪從吸入室吸進(jìn)液體。
First fill the booster pump with liquid, and then start the centrifugal pump. The impeller rotates rapidly. The blades of the impeller drive the liquid to rotate. When the liquid rotates, it flows to the outer edge of the impeller by inertia. At the same time, the impeller sucks liquid from the suction chamber.
在這一過(guò)程中，葉輪中的液體繞流葉片，在繞流運動(dòng)中液體作用一升力于葉片，反過(guò)來(lái)葉片以一個(gè)與此升力大小相等、方向相反的力作用于液體，這個(gè)力對液體做功，使液體得到能量而流出葉輪，這時(shí)液體的動(dòng)能與壓能均增大。
In this process, the liquid in the impeller flows around the blade. During the flow around movement, the liquid acts on the blade with a lifting force. In turn, the blade acts on the liquid with a force equal to the lifting force and opposite in direction. This force works on the liquid, so that the liquid gets energy and flows out of the impeller. At this time, the kinetic energy and pressure energy of the liquid increase.
氣液增壓泵工作原理類(lèi)似于壓力增壓器，對大徑空氣驅動(dòng)活塞施加一個(gè)很低的壓力，當此壓力作用于一個(gè)小面積活塞上時(shí)，產(chǎn)生一個(gè)高壓。通過(guò)一個(gè)二位五通氣控換向閥，增壓泵能夠實(shí)現連續運行。
The working principle of the gas-liquid booster pump is similar to that of the pressure booster, which applies a very low pressure to the large diameter air driven piston. When this pressure acts on a small area piston, a high pressure is generated. The booster pump can realize continuous operation through a two position five ventilation control reversing valve.
由單向閥控制的高壓柱塞不斷的將液體排出，增壓泵的出口壓力大小與空氣驅動(dòng)壓力有關(guān)。當驅動(dòng)部分和輸出液體部分之間的壓力達到平衡時(shí)，增壓泵會(huì )停止運行，不再消耗空氣。
The high-pressure plunger controlled by the one-way valve continuously discharges the liquid, and the outlet pressure of the booster pump is related to the air drive pressure. When the pressure between the driving part and the output liquid part reaches equilibrium, the booster pump will stop running and no longer consume air.
當輸出壓力下降或空氣驅動(dòng)壓力增加時(shí)，增壓泵會(huì )自動(dòng)啟動(dòng)運行，直到再次達到壓力平衡后自動(dòng)停止。采用單氣控非平衡氣體分配閥來(lái)實(shí)現泵的自動(dòng)往復運動(dòng)，泵體氣驅部分采用鋁合金制造。
When the output pressure drops or the air drive pressure increases, the booster pump will start automatically until it reaches the pressure balance again. A single gas controlled unbalanced gas distribution valve is used to realize the automatic reciprocating motion of the pump. The gas drive part of the pump body is made of aluminum alloy.
接液部分根據介質(zhì)不同選用碳鋼或不銹鋼。一般泵都有進(jìn)氣、排氣兩個(gè)口，在進(jìn)氣口能產(chǎn)生低于常壓（即大氣壓）氣壓的叫“負壓”；在排氣口能產(chǎn)生高于常壓氣壓的叫“正壓”。
Carbon steel or stainless steel shall be selected for the liquid receiving part according to different media. Generally, the pump has two ports of intake and exhaust, and the pressure that can be generated at the intake is lower than the normal pressure (that is, atmospheric pressure), which is called "negative pressure"; The pressure that can be generated at the exhaust port is higher than the atmospheric pressure is called "positive pressure".
比如常說(shuō)的真空泵就是負壓泵，增壓泵就是正壓泵。正壓泵跟負壓泵有很大的不同。比如氣體流向，負壓泵是外部氣體被吸入到抽氣嘴；正壓是從排氣嘴噴出去；比如氣壓的高低等。
For example, the often said vacuum pump is a negative pressure pump, and the booster pump is a positive pressure pump. Positive pressure pump is very different from negative pressure pump. For example, the flow direction of gas, the negative pressure pump is that external gas is sucked into the air extraction nozzle; Positive pressure is ejected from the exhaust nozzle; Such as the air pressure.
無(wú)論何種原因造成保壓回路壓力下降，增壓泵將自動(dòng)啟動(dòng)，補充泄漏壓力，保持回路壓力恒定。壓縮空氣、氮氣、水蒸汽、天然氣等均可做作為泵的驅動(dòng)氣源。關(guān)注我們

No matter what causes the pressure drop of the pressure maintaining circuit, the booster pump will automatically start to supplement the leakage pressure and keep the circuit pressure constant. Compressed air, nitrogen, steam, natural gas, etc. can be used as the driving gas source of the pump. Follow us http://m.liqun518.com Yes, learn more!
