Detailed Product Description: | Product Overview D-series multi-stage centrifugal pumps are single suction multistage centrifugal pump for conveying water with your physical and chemical properties similar to liquid water. The pump head is H23 to 153.6 meters, flow 12.6--39.6m3 / h. The maximum temperature of the liquid must not exceed 80 ℃ D-series multi-stage centrifugal Scope: Suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden irrigation, fire booster, long-distance water, heating, bathroom, heating and water circulation booster and Equipment, etc., especially for small boiler feedwater technical parameters: Flow: 6.3-300m3 / h; Head: 13-650m; Power: 2.2-400KW; speed: 1450-2950r / min; diameter: φ50-φ200; Temperature range: ≤105 ℃; Working pressure: ≤3.0Mpa D-series multi-stage centrifugal pumps Structure Description D-series multi-stage centrifugal pumps for multistage, suction in the water segment, into a horizontal direction, outlet in the water segment vertically upwards, its head may need to increase or decrease based on the use of pump series. Pump assembly is good or not, the impact on the performance of a great relationship, especially in the mouth of each impeller and guide wing and out of the center, which is about to make a slight deviation of the pump flow is reduced, reducing lift poor efficiency, it is important to note at the time of repair assembly . D-series multi-stage centrifugal pump main parts are: water segment, the middle, the water segment, impeller, guide wings baffle, the water segment wing guide, shaft, sealing ring, balancing rings, bushings, end caps and bearing body. Water segment, the middle baffle vanes, the water segment guide wings, the water segment and end caps are made of cast iron, together form the pump chamber. The impeller is made of high quality cast iron, there are blades, liquid axial unilateral entry, due to unequal pressure around the impeller, there must be an axial force, the axial force on the balance disc borne by the static balance test impeller manufacturing . Axis for high-quality carbon steel, middle mounted impeller, keys, bushings and bushing nut on the shaft. One end of the shaft is mounted coupling part, connected directly to the motor. Sealing rings made of cast iron, high-pressure water pumps to prevent water leakage back part, are fixed on the water and in the middle section, for wearing parts, replace worn parts availability. Balancing rings made of cast iron, is fixed to the water segment, which together constitute the balancing device with a balance. Balance disc is made of cast iron, mounted on the shaft, located between the water segment and end cap, balance the axial force. Bushings made of cast iron, located at the packing room, as fixed impeller and shaft-fitting protection for wearing parts, replace worn parts availability. Bearings are single row radial ball bearings, using calcium-based grease lubrication. Filler acts as a seal to prevent leakage of air entering and plenty of fluids, packing by water segment and end cap packing room, packing gland, packing ring and packing etc., filling the role of a small amount from the water seal chamber pressure water inflows. Tightness of filler must be appropriate, not too tight, not too loose also, to be able to drop by drop liquid oozing prevail. If the packing is too tight, bushings easy to heat, while consuming power. Packing too loose, fluid loss due to lower pump efficiency. D-series multi-stage centrifugal pumps Features: 1, hydraulic model of advanced, high efficiency, wide range of performance. 2, the pump runs smoothly, low noise. 3. Seal with soft packing or mechanical seals, seal safe, reliable, simple structure, convenient maintenance. 4, the shaft is fully sealed structure to ensure no contact with the media, does not rust, long service life.
