Boiler Feed Pumps in Sub & Super Critical Boiler



MHB



Multistage Barrel Casing Pump



Meet the demanding application with innovation and profession. As the world population increases the demand for power both domestic and industrial use grows. The trend is for utilities to construct larger power plants to meet this demand. As the capacity of the plants increase consequently the Boiler Feed Pumps increase in size. Torishima MHB pump for sub & super critical boiler is designed to meet these needs.

Design Features Super Stiff Rotor Ultra low static deflection Compact bearing span The lowest flexural critical speed in the pumped fluid is in excess of 130% of the maximum operating speed. Forged shaft High rotor balance quality Smooth running of the pump



Forged Barrel Casing and Cover FEM analysis adopted for design optimization Non destructive testing carried out 2-1/4% chrome material available as option



Tilting Pad Thrust Bearing Directed lubrication, double acting type Minimized power loss High thrust capacity (2 times design load) Accommodates residual axial thrust



Hydraulic Balancing Arrangement Straight balancing drum secured on the shaft Retention of hydrostatic stiffness with reduced leakage Residual axial thrust borne on the thrust bearing Long operating life with minimum wear



Full Cartridge Design The inner cartridge, which contains all the pump components except the barrel and main stud bolts, is removable from the barrel as a complete unit. This concept enables maintenance to be carried out in greatly reduced time. A set of hydraulic tensioning equipment and cartridge withdrawal gear will be supplied.



Pipe Connections Variable branch orientations to suit station pipework Optional flanges or welded nozzle connection Interstage tapping can be fitted



Optimized Hydraulic Components High efficiency CFD design to achieve low operating cost Interstage and Diffuser in 13% chrome stainless steel Precision cast impeller in 13% chrome stainless steel 1st stage impeller - super suction performance & minimum of 50,000 hours life Proven hydraulic performance Optimised suction guide geometry



Tilting Pad Journal Bearing Directed lubrication High rotor stability Long bearing life Plain sleeve bearing available as option



Shaft Sealing Cartridge Mechanical seal as standard Easy maintenance Proven seal life Suitable for COT operation in supercritical stations Labyrinth Glands available as option
