Description

With more than 15 000 units in use, the Voith variable speed fluid coupling re­presents one of the best documented options for controlling the speed of driven machines. These units generally have a service life of several decades. They can be deployed in areas ranging from high-efficiency gas and steam combined cycle power plants, to refineries and the highly demanding oil platform environment, as well as numerous fan applications. The hydrodynamic principle coupled with a simple structure give these variable speed fluid couplings the high reliability needed to excel under virtually any conceiv­able environmental conditions. In the power range from 100 kW to 10,000 kW and with input speeds up to 3,600 rpm, they enable cost effective, precise and step­less control of the speed of the driven machine. An adjustable scoop tube steplessly varies the coupling filling during operation. The coupling filling determines the power transmitted and consequently the speed of the driven machine. This type of speed control is simple, dynamic and reliable. The speed setpoint parameter uses a 4 – 20 mA standard signal. The integration of a Variable Speed Fluid Coupling into the drive train increases the productivity of your machine or plant.
