Centrifugal pump start principle

Centrifugal pump start principle Centrifugal pump is a vane pump, relying on the rotation of the impeller in the rotation process, due to the interaction of the blade and the liquid, the blade will be mechanical energy transfer to the liquid, the pressure of the liquid can increase to achieve the purpose of conveying liquid. Centrifugal pump to start to pay attention to four points: â‘ Centrifugal pump at a certain speed produced by the lift has a limited value. Operating point flow and shaft power depend on the condition of the system of the system connected to the pump (potential difference, pressure difference and line loss). Head changes with the flow. â‘¡ work stable, continuous delivery, flow and pressure pulsation. â‘¢ generally no self-absorption capacity, the need to pump the first filled with liquid or pipe pumping to a vacuum before starting work. â‘£ centrifugal pump in the discharge line valve is closed under the start, the vortex pump and axial pump in the valve fully open state to reduce starting power. Because the centrifugal pump is formed by the impeller centrifugal force to lift the vacuum suction, so the centrifugal pump starts, you must first close the gate valve, irrigation. Above the water level above the impeller, discharge the air in the centrifugal pump before starting. After start-up, a vacuum is formed around the impeller and the water is sucked upward. Its gate valve can be opened automatically and the water can be lifted. Therefore, the valve must be closed first.
