Product Overview

SHD,SHDG single-suction multistage segmental type centrifugal pump for conveyingwater or physical and chemical properties similar to water without solidparticles. SHD pumps transmission fluid with temperature below 80 ℃, suitablefor mines, factories and urban drainage. SHDG pumps transmission fluid with temperaturebelow 105 ℃, which is suitable for boiler feed pump or delivery of hot waterand other similar occasions.

Applications:boiler feed water, domestic water, fire water, circulation booster;

Structural features

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 berunning part. SHD-type pump with   horizontal inlet and vertical outlet, SHDGtype pump with both vertical inlet and outlet.

2,Rotor parts: the main by the shaft, impeller, balance plate and bushings andother 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 withreplaceable shaft sleeve for protection.

3,Bearingpart: 2 type of bearings: rolling bearings and sliding bearings:

Slidingbearing mainly by bearing body, bearing caps, bearing, dust disk, oil levelgauge, 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 andsealed body filler, retaining ring components at tail cover letter. Sealchamber liquid with function of the water seal, water-cooled and waterlubrication. SHD pump seal water from pressure water inside pump. SHDG sealwater from cooling water, normal temperature water outside pump.The pressure ofseal water should be higher than seal chamber 0.05-0.1MPa, the pressure of coolingwater to be 0.15-0.3MPa.

Inaddition, the pump is directly driven by a prime motor through flexiblecoupling. The pump is clockwise rotation, seems from the prime motor end.
