GC boiler feed pump structural features what?

[Asia Pump Network News] GC boiler feed pump horizontal single suction multistage centrifugal pump, mainly for boiler feed water, so aka boiler feed pump. Suitable for conveying clean water at temperatures below 110 ° C or other non-corrosive liquids with physico-chemical properties similar to water. Xiaobian now introduced under the GC boiler feed pump structural characteristics. GC boiler feed pump GC boiler feed pump main parts shaft, sleeve, inlet, impeller, guide wing, seal ring, the middle section, the water section, balance ring, balance plate, the tail cover. Into the water section, the middle section, the water section and tail cover are made of cast iron, together to form a pump studio. The impeller is made of cast iron, there are blades inside, the liquid enters along one side of the axial direction. Because the impeller is under pressure before and after, there must be axial force, which is borne by the balance plate. The shaft is made of high-quality carbon steel with an impeller in the middle, fastened to the shaft with key, sleeve and sleeve nut. One end of the shaft is equipped with coupling parts and is directly connected with the motor. When viewed from the direction of rotation, the pump shaft rotates clockwise. The sealing ring is made of cast iron to prevent the high-pressure water in the water pump from leaking back into the water part, respectively fixed in the water inlet section and middle section, which is a wearing part and can be replaced after being worn. Balance ring is made of cast iron, fixed in the water section, which together with the balance plate balance device. Balanced disc made of wear-resistant cast iron, mounted on the shaft, located between the outlet section and the tail cap, the balance of axial force. Sleeve made of cast iron, located in the two packing room for the fixed impeller and pump shaft protection purposes. For wearing parts, worn spare parts can be replaced. Bearing is a single row radial ball bearings, calcium-based butter lubrication. Packing seal from the inlet section and tailgate on the filling room, packing gland, packing ring and packing and other components, a small amount of high-pressure water into the packing room from the role of water seal. The degree of tightness of the filler must be appropriate, can not be too tight, nor too loose, the liquid can drip to exudate prevail. If the packing is too tight, the sleeve can easily generate heat while consuming power. Filler is too loose, due to liquid loss to reduce pump efficiency.
