Fluid coupling model works

is a hydraulic coupling passing the liquid medium speed machinery and equipment, and its active input shaft is linked with the original conveyor, driven output shaft and load shaft coupling, by adjusting the pressure of the liquid medium, so that the output shaft speed to be changed. Ideally, when the pressure tends to infinity, the output speed and input speed is equal to the equivalent steel couplings. When the pressure decreases, the output speed is reduced accordingly, continuously changing the medium pressure, the output speed can be lower than the input speed steplessly. Fluid coupling Hydraulic ferrules power control speed and efficiency of the principle of fluid coupling according to the above characteristics, can be equivalent to the model shown ispeed power control principles that drive speed changes, in essence, the result of mechanical power adjustment. Therefore, the output speed of the hydraulic coupler reduced, the actual output power is reduced. The governor during the original transmission fluid coupling speed does not change, assuming constant load torque, the original mechanical power transmission remains unchanged, then the difference between the input power and output power go of it, apparently by hydraulic coupling in the form of heat loss out. Therefore, we can not simply that hydrodynamic coupling speed is "lost turn", while the actual power is lost. Let the original transmission power of PM1, the output power of PM2, loss of power was is a fluid coupling energy-consuming mechanical control devices, speed deeper (lower speed) the greater the loss, especially constant torque load, since the original transmission input power constant, the speed power loss loss increases proportionately. For fan and pump load, the load torque at speed squared rate changes, the original transmission input power measured at the square of speed decreased, loss of power is relatively small, but the output power is reduced by the cube of speed ratio, speed efficiency is still low. Governor hydraulic coupling efficiency curve shows the average efficiency of around 50%
