The safety device not spraying liquid of hydraulic cam and groove coupling--Mechanical thermostat switch

　　In some application conditions of hydraulic cam and groove coupling, there are many environmental requirements both cleanliness and safety are more strict, is not a coupling medium from polluting the environment such as medical chemical industry, food processing, chemical gas and so on the condition, but when the spray liquid of cam and groove coupling overload protection is inevitable, it requires the normal use of device can guarantee the function of overload protection and no pollution to the environment. The mechanical temperature control switch ofr hydraulic cam and groove coupling is such.

　　Mechanical type temperature control switch is to fix a Fusible plugs not to spray the liquid on the cam and groove coupling shell, the opposite is installed with a limit switch.

　　The working principle of the mechanical temperature control switch: when the working fluid temperature of cam and groove coupling is over, When fusible alloy of fusible plugs not spraying liquid is melt, originally by fusible alloy solidification and a pin fixed in the action of the spring and the centrifugal force is ejected, limit switch hit the opposite, the motor stops, and overload protection.
