Feed Water Pump

Boiler feed water pump is the core pressurized conveying equipment of boiler thermal system. Its basic principle is based on multistage centrifugal fluid mechanics: the motor drives the pump shaft to rotate multistage impellers at high speed. Under centrifugal force, water flow is thrown from the center of the impeller to the outer edge, gains kinetic energy, and then converts kinetic energy into pressure energy through the guide vane and pump casing. Multistage impellers superpose pressure step by step, and finally convey the softened water from deaerator or water tank to boiler drum continuously with stable high pressure, ensuring the continuous and stable operation of boiler evaporation, heat exchange and steam output. It is an indispensable auxiliary machine for industrial boilers, power station boilers and heating boilers Reference: Baidu Baike · Boiler Feed Water Pump. As an original factory with more than ten years of experience in manufacturing pump valves and boiler supporting equipment, AIX Boiler takes independent R&D, precision manufacturing and full-process quality control as core advantages, creating special boiler feed water pumps suitable for medium and high pressure, large flow and long-cycle operation scenarios. Our products are widely used in chemical, metallurgical, electric power, paper making, park central heating and other industries, matching all kinds of steam boilers and hot water boilers from 1 ton to 220 tons, solving core pain points such as high-pressure water supply, stable flow, cavitation resistance and high temperature resistance, reducing procurement costs, improving operation efficiency and extending service life for users.

1. Core Structure and Working Advantages of AIX Boiler Feed Water Pump

AIX Boiler feed water pump adopts horizontal single-suction multistage segmented structure, which is composed of eight core parts: suction section, middle section, discharge section, guide vane, rotor parts, bearing assembly, shaft seal system and balancing device. All flow passage components are made of high-quality cast steel or stainless steel, resistant to high temperature, high pressure and corrosion, ensuring equipment stability and durability from the structural root. The rotor parts adopt high-precision impeller and rigid pump shaft combination, corrected by dynamic balance test, with small vibration and low noise during operation; the axial force adopts balance disc + thrust bearing combined compensation device, which automatically offsets axial thrust, reduces bearing load and prolongs continuous operation cycle; the shaft seal is equipped with standard mechanical seal, optional packing seal, matched with cooling and flushing structure, effectively preventing leakage, suitable for high-temperature water supply conditions of 105℃—250℃ Reference: AYi Network · Selection and Maintenance of Boiler Feed Water Pump. As an original factory, AIX Boiler realizes independent control of the whole chain from casting processing, parts assembly, performance testing to factory commissioning, refusing OEM. Each pump has passed multiple authoritative verifications such as hydraulic test, performance bench test, vibration and noise test, temperature rise test, ensuring factory performance and reliable operation.
