Flexible Shaft
Flexible Shaft is used for cleaning /de-scaling the internal surface of the tubes of any heat exchanger. Its function is to transmit vibration free constant power/ torque from the flexible shaft machine to the tool being used for de-scaling.
The Flexible shaft consists of,
Inner Core:
It is flexible wire with multiple wound opposite layer. It is made from special quality, high tensile spring steel wire and passed through heat treatment processes to make it absolutely vibration free.
Outer Casing:
It is flexible, double interlocked, circular rounded, made of galvanized steel strip. The outer casing is provided with flat spring steel spiral lining throughout the length to reduce friction between the inner core & outer casing so as to attain maximum life and wear resistance.
Connection:
One end of shaft with machine end socket is attached to suitable motor and other end is attached to tool end.
