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?
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.
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.
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.
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.
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.
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".
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.
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://www.allarabandroid.com Yes, learn more!
