CBL EPCV’s have two types.Type `(direct connection type)and Type a(compartment type),The Fan is a no-spark design.
I(Direct Connection Type)The EPCV’s is directly driven by the explosion-proof motor.In this type,The impeller is directly fixed on the motor shaft and the casing maunted on the flange of the explosion-proof motor.
The EPCV’s structure is either in a horizontal,single-stage single-drawing and air tight structure,or in a structure.
The EPCV’s can also be manufactured as compartment type,according to the vertical’s requirements.In the type,the EPCV and the motor are separated in different cabin with gearing customer’s and sealing stuffing box as well as flexible couplings fixed in between.
The EPCV’s can be set either left rotation or right rotation.
Left rotation,marked L,refers to the counter-clockwise rotation of the impeller from the view of the motor.
Right rotation,marked R,refers to the clockwise rotation of the impeller from the view of the motor.
The posion of the air outlet is basically made into following types according to the different rotation of the impeller.
According to the requirements,the outlets can adopt other forms changing with 30°or 22.5°increment.
