Due to the rotation of the shaft sealing device shaft pump housing is fixed, at the contact of the shaft and the pump housing must have a certain gap. To avoid a high pressure liquid pump leakage along the gap, or to prevent outside air from entering the pump from the opposite direction, you must set the seal device. Seal means of centrifugal pumps have stuffing and machinery (end) seal. Stuffing is the shaft of the pump casing annulus through the seals made, in which the load soft filler (such as oiled or coated graphite asbestos rope, etc.). Mechanical seal is mounted on the shaft of a ring and the other fixed to the casing of the stationary ring of the composition. Two end faces of the ring by the spring force and close contact with each other for relative rotation, played a seal. Mechanical seals suitable for higher sealing applications, such as transportation acid, alkali, flammable, explosive and toxic liquids. When the centrifugal pump starts, the impeller shaft drive for high-speed rotational movement together, forcing the liquid previously filling in the gaps between the blades rotating 125D-25 * 9 stainless steel multi-stage pump, the role of the centrifugal force of inertia, the liquid from the center outward as the impeller diameter week motion. The liquid flowing through the impeller during movement energy obtained 150D-30 * 4 stainless steel multi-stage pump, can be increased static pressure, the flow rate increases. When the liquid exits into the centrifugal impeller housing, since housing flow channel gradually expand and decelerate, some kinetic energy into static pressure energy, last tangentially flows into the discharge line. So volute casing is to bring together not only by the fluid discharged from the impeller parts, and it is capable of a transfer device. When the liquid thrown from the center toward the outer periphery of the impeller while 150D-30 * 3 stainless steel multi-stage pumps, impeller formed in the center area of ??low pressure, the role of the tank liquid level and the total potential energy difference between the center of the impeller, causing the liquid to be sucked into the center of the impeller. Rely on the continued operation of the impeller, the liquid will be continuously suction and discharge. The mechanical energy of the liquid obtained in the final performance of a centrifugal pump to improve the static pressure energy. Impeller role is the original motivation of the mechanical energy directly to the liquid, to increase the static pressure of the liquid and kinetic energy (mainly to increase static pressure).
