Working principle of water pump




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 relying on inertia. At the same time, the impeller sucks in the liquid from the suction chamber. During this process, the liquid in the impeller flows around the blades, and during the flow around the blades, the liquid acts as a lift force, which in turn acts on the blades with a force equal in magnitude and opposite in direction to this lift force, This force does work on the liquid, causing it to receive energy and flow out of the impeller. At this point, the kinetic energy and pressure energy of the liquid increase.




The working principle of gas-liquid booster pump is similar to that of a pressure booster, which applies a very low pressure to the large diameter air driven piston. When this pressure acts on a small area piston, it generates a high pressure. The booster pump can achieve continuous operation through a two position five ventilation 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 driven 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 automatically stops. The automatic reciprocating motion of the pump is achieved by using a single gas controlled non-equilibrium gas distribution valve, and the gas drive part of the pump body is made of aluminum alloy. Carbon steel or stainless steel should be selected for the liquid receiving part according to different media. Generally, pumps have two ports for intake and exhaust, and the pressure that can be produced at the intake port below atmospheric pressure is called negative pressure; The pressure that can generate above atmospheric pressure at the exhaust port is called "positive pressure"; For example, the commonly mentioned vacuum pump is a negative pressure pump, and the booster pump is a positive pressure pump. Positive pressure pumps are very different from negative pressure pumps. For example, in terms of gas flow direction, a negative pressure pump sucks external gas into the suction nozzle; Positive pressure is sprayed out from the exhaust nozzle; For example, the level of air pressure, etc.
