  The fusible plug is overheating protection device load or braking; explosive plug is over-voltage protection device of hydraulic coupler themselves too much pressure burst.

  When the ordinary torque limited hydraulic cam and groove coupling is in overload, the output speed sharply declines until the stop. When the motor rotates as usual,hydraulic cam and groove coupling pump and turbine slips, increase efficiency, reduce. Damaged power into heat makes the work liquid cam and groove coupling rapidly warming, boost. If not timely release, temperature and pressure may exceed the bearing capacity cam and groove coupling shell and liquid ignition, explosion, fire occurrence coupling and malignant accident. So we must set the safety protection device, ensure that the coupling in overload, can rapidly unloading, avoid accidents. The fusible plug is safety protection device of hydraulic cam and groove coupling.

  The appearance of fusible plug is similar to the general screw plug, and has a small hole on the core part, which cast alloy. When the coupling overload heating to melting temperature fusible alloy, the fusible alloy melts, working liquid is ejected from the hole under the action of centrifugal force, cut off input and output overload protection of the power, safety protection applies to all cam and groove coupling.
