Whether The Hydraulic Coupling Is Not Oil Can Not Transfer Power?
Sep 30, 2017

There is no direct mechanical connection in the hydraulic coupling that relies entirely on the kinetic energy of the liquid; if it is not filled, the pump wheel and the turbine in the coupling will not be connected. Pump rotation and the turbine does not turn, the input and output can not be coupled connection, it can not transmit torque and power, so the coupling must be required to fill the right liquid.

Why is the ability of the liquid coupling to transmit power to be substantially proportional to the liquid filling rate? Because the hydraulic coupling is to rely on the kinetic energy of the liquid transmission power, so in the provisions of the liquid filling range, the more liquid flow the greater the power transmission, filling less power less transmission. The ability of the liquid coupling to transmit power is substantially proportional to its liquid filling rate.
