Working principle of pipeline centrifugal pump

Pipeline centrifugal pump working principle is: centrifugal pump so the water can be sent out is due to the role of centrifugal force. Pump before work, pump body and water tank full of water to form a vacuum, when the impeller rotates fast, it leaves the water to quickly rotate, rotating the water under the centrifugal force from the impeller to pump [1], was thrown out of the water, the central part of the impeller formed vacuum region. The water in air pressure (or pressure) through the pipe network under the inlet pressure to the inside. This cycle, you can achieve continuous pumping. This is worth mentioning: centrifugal pump before the start must be full of water to the pump shell, can start, otherwise it will cause the pump body heat, vibration, reduce the amount of water, damage to the pump (referred to as "cavitation") cause the accident of the equipment!
