Before single-stage centrifugal pump start, pump shell filled with liquid to be transported; after startup after startup, the impeller shaft driven by high-speed rotation, the liquid between the blades must also be with the rotation. Under the effect of centrifugal force, the liquid is thrown from the center of the outer edge of the impeller and get energy at high speed away from the outer edge of the impeller into the volute casing. In the volute, the liquid due to the gradual expansion of the flow channel and the deceleration pipeline circulating pump, in turn part of the kinetic energy into static pressure energy, and finally to a high pressure flow into the exhaust duct, to the need to place. Liquid flow from the center of the outer edge of the impeller pump a multistage pipeline, the center of the impeller to form a certain vacuum, the pressure tank above the liquid surface is greater than the pump inlet pressure, the liquid will be pressed into the impeller continuously. Visible double suction pump, just keep rotating impeller, the liquid will continue to be the suction and discharge. Basic components are high-speed centrifugal impeller rotating and stationary snail-shaped casing. Has several (usually 4 to 12) after the curved impeller blades secured to the pump shaft and driven by a motor with a high speed shaft rotation. The impeller is directly acting on the components of the liquid pump, means for energizing the centrifugal pump. The center of the pump casing suction port is connected to the suction pipe, the bottom end of the suction pipe is provided with a one-way valve. Regulating valve outlet and equipped with exhaust pipe connected to the side next to the pump casing. Chengdu pump _ West pipeline circulating pump _ Baoquan Baoquan water provided by the West.
