GENERAL DESCRIPTION
JCL series Marine Centrifugal Exhaust Fan is designed and manufactured according to the standards of the state for GB11865 « Marine Centrifugal Ventilator» , GB11864 « Marine Explosion-proof Axial Flow Fans» « Rules and Regulations for the Construction and Classfication of Sea-going Steel Ships» And « Rules and Regulations for the Construction of PLA Naval Ships» . This series fans have been examined by China Classification Society and have got the certificate. They are also approved by the authority of shipping equipment and research staff.
STRUCTURE TYPE
JCL type fan is of horizontal, single-stage and single-drawing type with direct connetion for the motor. It can also be constructed into a vertical type with the vane wheel on the motor shaft. The vane wheel is riveted with aluminium alloy. They have calibrated under both static and dynamic balance. Both the machine casing and the inlet are made of welded common steel with airtight structure. The fan can be made for counterclockwise (left) or clockwise (right) rotation, counterclockwise (left) rotation: Viewed from the motor side, the vane wheel rotates anticlockwise and indicated as "L". Clockwise (right) rotation: Viewed from the motor side, the vane wheel rotates clockwise and indicated as "R". According to the rotating direction of vane wheel, the outlet position of fan is made into the following main types. In conformity with the requirement, the outlet position is allowed to use other types, the angle of which is 30° Or 22.5° .
APPLICATION
