The requirement of running conditions may be satisfied by regulating electric actuator and the angle ofguide vane through transmission shaft.5.7 Companion flangesCompanion flanges are provided for easy installation, and the user may weld his connecting pipes onto the suction and discharge flanges separately.6. Fan InstallationBefore installation, foundation should be prepared according to the basic dimension sketch of fan and electric motor and keep enough space for secondary grouting. At the same time, required materials, tools and equipments should be prepared (Lifting weight of biggest fan parts is 2343 kg), on the other hand, the packed parts of fan should be checked, the parts in case of damage, should be repaired and replaced immediately.Impeller and main shaft should be checked more carefully, inner of bearing box should be cleaned with kerosene. Cooling water pipe should be cleaned up without any obstruction.In order to prevent rust and reduce disassembly difficulty, lubricating grease or machine oil should be coated on the connecting surface. The connection bolts should be tightened after position pin is in place.Tighten the anchor bolts temporarily for the installation of casing with anchor bolts, check casing and pipes inner carefully, and make sure that noforeign matters, such as tools are left inside.Installation Steps:(1)Place anchor bolts first, and then put lower casing in position.(2) Put the bearing baseplate and lower bearing in position, axial and horizontal leveling should be made with reference to the hole of bearing and deviation of which should be no more than 0. 10 mm/ m.(3)Put the assembled rotating parts (including impeller, main shaft, bearing,oil whip ring etc.) into the bearing baseplate.(4)Assemble the upper cover of bearing box, measure clearance between oilseal and oil whip disc according to the dimensions provided on the drawings of journal bearing and thrust bearing, and ensure that radial clearance of main shaft and oil seal is uniformly filled with asbestos packing, tighten side covers and oil seals on two ends, connect cooling water pipe and then fill bearing box with new lube oil.(5)When installing suction, axial and radial clearance between suction andimpeller should be adjusted according to required dimension on general drawing of fan in order to guarantee high efficiency of fan.(6)Put the upper casing in position and tighten bolts between suction andcasing.(7)Connect inlet box with suction.(8)Pay attention to direction of the damper during assembly。

CATALOG AX200 | JANUARY 2013WWW.TCF.COMMODEL TCTATCVA AXIFAN® Vaneaxial Fan, except that guide vanes are notprovided. This makes the TCTA more suitable for lower pres-sures and provides cost savings.Capabilities• Wheel diameters 12" to 60"• Airflow to 96,000 CFM• Static pressures to 5" w.g.• 37 unique diameters and hub-to-tip ratiosAXIFAN® WheelThe heart of the TCTA AXIFAN® fan lies in its wheel. Cast ofhigh strength aluminum alloy, the one-piece TCTA AXIFAN®wheel has been developed to maximize the highest efficiencypossible. Attention to detail in blade and hub design have cre-ated what is felt to be the most efficient and reliable axial fanon the market today. With the wide range of hub-to-tip ratiosavailable, there is a TCTA AXIFAN® to meet any air movementrequirement.Hub-To-Tip RatioThe multitude of TCTA AXIFAN®wheels evolves from ninebasic castings. Each casting is machined and cut to the properdiameter. By cutting the same model casting to one of severaldifferent diameters, different hub-to-tip ratios are created. Sinceeach hub ratio has slightly different pressure/efficiency charac-teristics, the freedom of having several wheels (different hubratios) for a set diameter provides the opportunity to maximizeefficiency at the required point of rating.HousingTCTA AXIFAN® housings are one-piece, heavy-gauge, hot-rolledsteel construction. Flanges on both the inlet and outlet are inte-grally rolled and punched for attachment to ductwork or acces-sories as necessary. The seam is continuously welded andground smooth to assure efficient airflow through the housing.Drive Isolated from AirstreamThe shaft and bearing assembly is mounted within the innercylinder to isolate these components from the high velocityairstream.The V-belt drive assembly is extended through a two-piece beltfairing. The belt fairing is an aerodynamically designed tube,designed to maximize fan efficiency, minimize air blockage andreduce noise generation.Additional InformationFor additional information on the TCTA and TCVA AXIFAN®tubeaxial and vaneaxial fans, refer to Twin City Fan & BlowerCatalog AX100.This catalog contains performance tables for Arrangement 9belt driven fans.
