Standard Conventional Temperature For Fusible Plug

The fusible plug is an overheat protective device of the coupling, which is one of the indispensable coupling accessories, which is mounted on the coupling shell.

When used for cooling water circulation pump damage or cooler, the working oil temperature rise sharply in the coupling, and close to the working oil flash point, work will cause oil on fire, even the worst effects of the coupling damage.

But after installed easy let plug, as long as the work of oil temperature is close to 100 ?, fusible plug of the low melting point alloy will melt, working oil under the action of centrifugal force, spewing from the fusible plug, make active part and the driven part completely disconnect, no longer transmission torque, so as to protect the motor, coupling, and follower.

Malfunction must, at this time in accordance with the provisions, the amount of oil filled with new oil, change to the original specification as fusible plug or again poured into the low melting point alloy, at the same time, the coupling on the circumference of a circle all the bolt fastening once again.

Fusible plug standard normal temperature T = 125 ? + / - 5 ?. The frequent start or heavy large inertia load start condition for a longer time, can choose 140 ? or 160 ? of fusible alloy, but may affect the service life of shortening the skeleton oil seal, please choose carefully. Special low melting point alloy fusible plug tiny after solidification shrinkage can ensure the normal operation of hydraulic coupling request remove hydraulic coupler fusible plug, oil plug, explosion-proof plug, the human body and facial oil injection direction, should avoid the plug body with wrench unscrew body a few buttons and stay for a period of time after release coupler cavity pressure, to completely fill body, prevent coupling medium fluid due to high temperature hurt.

Do not use unqualified fusible alloy plug, explosive plug, explosive film.
