The classification of fanner reachs applied domain

1.

The classified   of fanner presses structure and working principle, make fanner the following classification: 1.

2.

The fanner of applied   of fanner applies at each industrial departments widely, tell commonly, centrifugal type fanner applies to the place of force of little flow, high pressure, and fanner of axial shedding type is commonly used the circumstance at large flow, low-pressure force. One, boiler uses fanner foundation with boiler of fanner   the norms of boiler can choose centrifugal form or the axis sorts type. The action cent that presses it again is boiler fanner, to air is carried inside boiler; Boiler brings fan, pump the flue gas inside boiler. 2, ventilated take a breath uses fanner   this kind of fanner is to offer a factory to reach all sorts of buildings commonly ventilated take a breath and heating are ventilated with, demand pressure is not high, but noise asks to want low, can use centrifugal type or axis to shed type fanner. 3, industrial furnace (furnace of cupola, forging, metallurgy furnace) with fanner   this kind of fanner asks pressure is higher, it is 2940 ～ commonly ｍ of ／ of forteen thousand seven hundred N 2, namely high pressure is centrifugal the limits of fanner. Because of pressure tall, impeller is circumferential rate is old, the impeller when reason is designed should have enough strength. 4, mine uses fanner   it has two kinds: One kind is advocate fanner (say again advocate fan) , use fresh air, its flow is larger, use an axis to sort type more appropriate, of useful also and centrifugal type; Another kind is local fanner (weigh bureau fan again) , those who be used at mine working face is ventilated, its discharge, pressure all small, use explosion proof axis to shed type fanner more. 5,   carries coal fines fanner the coal fines of system of combustion of hot utility boiler, use centrifugal type fan more. Coal fines fanner differs according to utility can divide kind: One kind is fanner of coal fines of Chu Cang type, it is by its the coal fines inside Chu Cang flank blows the chamber of a stove or furnace inside, coal fines does not carry fan directly, the exhaust pressure of requirement fanner is high; Another kind is to blow fanner of type coal fines continuously, it sends the chamber of a stove or furnace coal fines directly. Because coal fines is right,impeller and body carapace wear away serious, reason should use wear-resisting data. CNC Milling
