Electric Tube Expansion System

Torque Controlled Tube Expansion System / Current Based

BHARTIYA Electric Tube Expansion Drive Unit is governed by a separate Electric Control Panel which is adjusted by a simple Digital Display. When the Electrically Driven Motor reaches the desired Torque, the Control unit Mechanism automatically shuts off the Power and on pressing the Reverse Button the Tube Expander retracts out from the Tube. The Fully Automatic system ensures the Tube are rolled to maximum tightness without excessive cold worked stress in Tube Metal which prevents injuring Tube ends or distorting Tube Sheet Ligaments.

Note:
Latest Design Highly Advanced - Micro processor based torque control unit - Also available - quote on request.

Electric Torque Controller / Wattage Based

01.	Fully Solid State Design - no moving parts - no wear and tear - no noise - consequently long life.
02.	Uses the latest micro-controller chip for control functions.
03.	Uses one main circuit board for easy maintenance.
04.	Accurately calibrated digital torque setting with a resolution of 1 watt makes torque settings accurate and can be easily reproduced for identical results.
05.	Connected drive is automatically recognized & indicated by means of LED on the torque controller.
06.	Soft start has been provided for all drives, which reduces starting currents in the drive. As a result, life of carbon brushes & drive increases.
07.	Torque setting arranged in four different ranges to suit four different drives. Appropriate wattage range is automatically selected for the connected drive, hence drives can not be abused or overused.
08.	Actual drive wattage (torque) is displayed. Set wattage (torque), drive current and line voltage can be seen be Press of a button.
09.	Adjustable reverse time from (1 sec to 100 secs.)
10.	Trip time adjustable from (0.1 sec to 10 secs.)
11.	Pause time (time interval between cycles) adjustable from ( 1 sec to 100 secs.)
12.	Manual reverse by push button, in case of emergency.
13.	Drive Speed adjustable in reverse rotation.
14.	Hand (trigger) mode or foot switch mode, both are available.
15.	Expansions can be carried out either in single cycle mode or auto repeat mode.
16.	MCB has been provided to protect the drives against over current by short circuits..
17.	Plug in type PCBs reduce down time to minimum during trouble shooting.
18.	LED indicators provided for forward, reverse & trip conditions of drive.
19.	Superior SCR technology has been incorporated rather than trics. SCRS have much better voltage, current & dv/dt ratings than triacs. This leads to greater reliability & the power circuit becomes almost failsafe.
20.	All the spares inside the panel viz : PCBs, Transformers, CT, Relays DPM etc. Can be replaced by use of only a screw driver.
21.	PC/Printer compatible.
