How does a pump pump water?
Generally speaking, pumps mostly refer to centrifugal pumps. Generally, the centrifugal pump is driven by an electric motor. Before the pump is started, the pump body and the suction line are filled with liquid. When the high-speed rotation of the impeller, the impeller drives the liquid between the blades of a rotation, due to the centrifugal force, the liquid was thrown from the impeller center to the outer edge of the impeller (flow rate can be increased to 15 ~ 25m/s), the kinetic energy is also increased. When the liquid enters the pump shell, the flow rate of the liquid gradually decreases as a result of the gradual expansion of the flow passage in the volute pump housing, and a part of kinetic energy is converted to static pressure, so the liquid flows out at the higher pressure along the outlet. At the same time, the impeller center because the liquid was thrown out and formed a certain vacuum, and the liquid level of pressure Pa than the center of the impeller to be high, so the suction pipe of the liquid in the pressure difference into the pump. The impeller keeps rotating and the liquid is continuously sucked in and out. Centrifugal pump is able to transport liquid, mainly due to centrifugal force, so called centrifugal pump.
Centrifugal pump is centrifugal force, and household deep well pump is primary pressure
Centrifugal pump is the use of centrifugal force to increase the pressure of water and make it flow of a pump. It is composed of pump shell, impeller, rotating shaft and so on. The motor drives the rotating shaft, the rotating shaft drives the impeller to rotate at a high speed in the pump casing, and the water in the pump is forced to rotate with the impeller to generate centrifugal force. The centrifugal force forces the liquid from the impeller periphery to throw, the high speed, the high pressure water flows through the pump shell outside the pump, the impeller center forms the low pressure, thus draws in the new water flow, forms the unceasing water current transportation function.
