Used Blast Furnace Centrifugal Fan

Product Description

D Series blower is used to provide sufficient air for smelting blast furnace orChemical industry, it is an important part of the blast furnace production.

This type blowerïs inlet and outlet both are downward, the traditional two floors are used for the layout. The core unit of centrifugal blower, gear box and motor are arranged in the second floor, the control is located next to the machine train, which is easy to observe and operate. The lube oil station, valves, inlet & outlet valves are arranged in the first floor because of high discharge temperature, which need very good ventilation condition.

This type blower adopts the most advanced high efficient three-dimensional centrifugal blower Design and manufacturing technology. The integral machine train is featured by good quality and reliable condition and the efficiency is 8ï10% higher than normal two-dimensional design.

The three space torsional blades, impeller disc and main shaft for the whole impeller of rotor is made up of high strength alloy steel, the impeller shall be made integral heat treatment and process quality conditioning after welding, which can guarantee the impellerïs whole crystal organization precision and also eliminate stress after welding, thus greatly increase the safety and reliability of impeller. Each impeller shall be done over-speed test with 15% working speed and the whole rotor shall be done with high precise dynamic balance test to guarantee stable and reliable operation.

Both the casing and diaphragm use resin sand casting, with higher density and bright appearance, each joint surface is sealed and reliable after precision machine and scraping.
