Fluid coupling refueling much

Fluid coupling refueling much ?Amount of oil hydraulic coupling hydraulic coupling with the specifications has its transmission torque range , called the power band , the power band filled with coupling corresponds to the range . Typically, the fluid coupling coupling  Hydraulic tube fittings fluid-filled range should be 60% ​​of the total volume to 80%, not outside this range can not be filled .When the fluid coupling fluid-filled volume exceeded 80% of the time, coupling in the rotation, due to sharply boost heating overload , resulting in the expansion of the working fluid volume , increased pressure within the coupling device , it will destroy oh seal , causing leakage, or cause cracking of the housing of the coupling , resulting in damage to the machine .
