Industrial Fluid Couplings
Dynamic Trading Company offers a range of Industrial Fluid Couplings. When the Elecon fluid coupling is filled with oil to the appropriate level and the motor is switched on, oil in the passages between the vanes of the impeller is accelerated radially outwards gaining energy all the time until it reaches the maximum circuit diameter. The oil then passes from the impeller to the runner in which it is forced to move inwards between the vanes and as its radial velocity falls energy is transferred to the runner and output shaft. Because the oil passes directly from the impeller to the runner, (there is no reaction member, as in a torque converter), the efficiency is high, with full load slips of between 2 and 5% being achieved in practice and depending on the application and size selection. Windage and oil circulation losses are negligible therefore efficiency equals 100% slip %. Should an overload occur the fluid coupling would stall, i.e., slip 100% at a torque value determined by the initial oil filling level. Thus motor and machine are both protected. The level of performance achieved by a fluid coupling is governed mainly by the design of its working circuit which includes the shape of the circuit, number of vanes in the circuit, the vanes placement etc. The working circuit developed by Elecon is out of number of years of experience in the field and is vital in the performance of the fluid coupling. Elecon fluid couplings are very rugged in construction, simple in design and reliable in operation. When Elecon fluid coupling is connected to the drive system it allows the motor to start practically at no load. This results in reduced starting current enabling quick start and acceleration of the drive motor.
