Description

Transfluid has designed their KSL series variable fill fluid coupling to overcome problems experienced at “start up” and “speed variation” operation for medium and high power machines, driven by electric motors and internal combustion engines. WORKING OPERATION Extremely efficient perfomance is achieved operating the KSL’s very simple and effective principle. Oil, that’s the power medium, is pumped from a sump to the hydrodinamic coupling circuit, where it is finally “drained off” through a series of orifice plugs, back into the sump. The “START UP” principle: By controlling the coupling’s feed pump oil flow to the working circuit by a small A.C. frequency converter, changes occur inside the coupling working circuit which alter the coupling slip characteristics and this softens the “start up” dramatically. The “VARIABLE SPEED” principle: The same principle used to control the start-up permits the KSL to operate as variable speed drive, varying the speed between input and output. Its “TORQUE LIMITING” function: Another KSL feature is its ability to limit the torque transmitted, slipping for a time and then dumping its circuit oil, disconnecting the driven machinery. The quick disconnection is possible by installation of quick realease valve. The key “KSL” features are: soft start variable speed torque limiting
