The fusible plug CO46-02-12A plays an important role in hydraulic couplings. It is installed on the rotor and sprays working oil outwards to achieve the working principle of the hydraulic coupling.

In the hydraulic coupling, the working oil flows from an open circuit to a closed circuit, filling the working oil chamber. During this process, the excess working oil supplied by the working oil pump will return to the oil tank through the pressure holding valve. When the filling amount of the coupling decreases, excess working oil will also return to the tank through this pathway. The setting of the operating pressure of the working oil is related to the pressure holding valve, which can ensure the normal operation of the hydraulic coupling.

Another important function of the fusible plug CO46-02-12A is to protect the hydraulic coupling from overheating damage. If the closed loop circuit is damaged and the coupling oil temperature rises to 160, the fusible plug will melt and the working chamber of the coupling will discharge oil outward. This can prevent the internal temperature of the coupling from continuing to rise, thereby avoiding equipment damage.

Of course, if the melting of the fusible plug CO46-02-12A is caused by short-term overheating of the oil circulation, such as oil cooler failure or coupling overload, the adjustment performance of the coupling will only slightly change. This is also an advantage of the fusible plug CO46-02-12A, which can effectively deal with various problems during the operation of the coupling and ensure the stable operation of the equipment.

Overall, the fusible plug CO46-02-12A plays a crucial role in hydraulic couplings. It not only ensures the normal operation of the coupling, but also has the function of protecting the equipment from overheating damage. Through its unique melting mechanism, it can deal with various problems during the operation of the coupling and ensure the stable operation of the equipment.
