SHD, SHDG single-suction multistage segmental type centrifugal pump for conveying water or physical and chemical properties similar to water without solid particles. SHD pumps transmission fluid with temperature below 80'C, suitable for mines, factories and urban drainage. SHDG pumps transmission fluid with temperature below 105'C, which is suitable for boiler feed pump or delivery of hot water and other similar occasions.
Applications: boiler feed water, domestic water, fire water, circulation booster;
Performance advantages: small footprint, energy efficient, stable, reliable, easy to maintain;
Flow 6-800m3/hr; Head 25-650m; Speed 1450-2900rpm;
Medium temperature 0-105'C;Diameter 40-300mm;
SHD, SHDG type pumps made from stator, rotor, bearings and shaft seal.
1, Stator part: mainly by inhalation, middle, spit section, guide vanes, etc., clamping segments with tension bolts to be running part. SHD-type pump with horizontal inlet and vertical outlet, SHDG type pump with both vertical inlet and outlet.
2, Rotor parts: the main by the shaft, impeller, balance plate and bushings and other components. The shaft transfer power to the impeller to make it work; axial force is balanced by balance plate; both ends of the shaft equipped with replaceable shaft sleeve for protection.
3,Bearing part: 2 type of bearings: rolling bearings and sliding bearings:
Sliding bearing mainly by bearing body, bearing caps, bearing, dust disk, oil level gauge, rejection mooring rings and other components, lubrication of thick oil; Rolling bearing main body, bearings and gland, using grease lubrication.
4, Shaft seal parts: mechanical seal or packing seal, mainly by water segment and sealed body filler, retaining ring components at tail cover letter. Seal chamber liquid with function of the water seal, water-cooled and water lubrication. SHD pump seal water from pressure water inside pump. SHDG seal water from cooling water, normal temperature water outside pump.The pressure of seal water should be higher than seal chamber 0.05-0.1MPa, the pressure of cooling water to be 0.15-0.3MPa.
In addition, the pump is directly driven by a prime motor through flexible coupling. The pump is clockwise rotation, seems from the prime motor end.
