What is the working principle of MEGI booster pump and other booster pumps?
First, fill the booster pump with liquid, then start the centrifugal pump. The impeller rotates rapidly, and the blades of the impeller drive the liquid to rotate. When the liquid rotates, it flows towards the outer edge of the impeller by inertia. At the same time, the impeller sucks in the liquid from the suction chamber. In this process, the liquid in the impeller flows around the blades. During the flow, the liquid acts on the blades with a lift force, which in turn acts on the liquid with a force equal in magnitude and opposite in direction to this lift force. This force does work on the liquid, causing it to gain energy and flow out of the impeller. At this time, the kinetic energy and pressure energy of the liquid both increase.
The working principle of a gas-liquid booster pump is similar to that of a pressure booster, which applies a very low pressure to a large-diameter air driven piston. When this pressure acts on a small area piston, a high pressure is generated. The booster pump can operate continuously through a two position five air control directional valve. The high-pressure plunger controlled by a one-way valve continuously discharges the liquid, and the outlet pressure of the booster pump is related to the air driving 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 automatically start running until it reaches pressure balance again and then stop automatically. The pump adopts a single gas controlled non-equilibrium gas distribution valve to achieve automatic reciprocating motion, and the gas driven part of the pump body is made of aluminum alloy. The liquid receiving part is made of carbon steel or stainless steel according to different media. Generally, pumps have two ports for intake and exhaust, and the one that can generate a pressure lower than atmospheric pressure at the intake is called "negative pressure"; The ability to generate a pressure higher than atmospheric pressure at the exhaust outlet is called "positive pressure"; For example, the commonly referred vacuum pump is a negative pressure pump, and the booster pump is a positive pressure pump. There is a significant difference between a positive pressure pump and a negative pressure pump. For example, in terms of gas flow direction, a negative pressure pump draws in external gas into the exhaust nozzle; Positive pressure is sprayed out from the exhaust nozzle; For example, the level of air pressure.
