D-type horizontal multi-stage pump is single suction multistage centrifugal pumps for suction of water and physical and chemical properties similar to water or liquids. Liquid maximum temperature not exceeding 40 ℃ multistage pumps suitable for mine drainage, factories and urban water supply purposes. D-type pumps are single suction multistage centrifugal pumps, with advanced and reasonable structure, high pump efficiency, cavitation resistance, vibration, smooth and reliable operation, long life and other advantages. The product is a reasonable performance, saving energy 100D-24 * 3 multi-stage pump, practical, cost-effective flow Q: 21 ~ 720m3 / h, Head: 28.8 ~ 1000m temperature range ≤80 ℃ This series of pumps for conveying water below 80 ℃ or Other physical and chemical properties similar to water, is the ideal mine drainage, suitable for petroleum, chemical, metallurgy and factories, urban, water supply and drainage. D6-25x3D6-25x4D6-25x5D6-25x6D6-25x7D6-25x8D6-25x9D6-25x10D6-25x11D6-25x12D12-25X3D12-25X4D12-25X5 shaft sealing device due to the rotation shaft of the pump housing is fixed, at the contact of the shaft and the pump housing inevitable there is 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. By the spring force of the two end faces of the ring and snapping each other for relative rotation 100D-24 * 9 multi-stage pump, 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 pre-filling liquid between the blades rotate, the role of the centrifugal force of inertia, the liquid from the outer periphery of the impeller hub for radial movement. Liquid flow through the impeller during movement gained power, static pressure can increase 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 at the same time, the impeller formed in the center area of ??low pressure in the tank liquid level and under the center of the impeller of the total potential energy difference 100D-24 * 2 multi-stage pump, 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).
