.3 Valve-specific motor performance
.3①The valve motor torque conforms to the valve's opening and closing torque characteristics. Generally, the torque value required for a short time to open and close a valve is high, while in the intermediate operating state, the required torque value is only 1/3 of the maximum torque value for opening or closing, so the valve is equipped with a special motor. It is characterized by high starting torque and strong overload capability. The ratio of the maximum torque of the valve-specific motor to the rated torque value is greater than 3 times, and the ratio of the starting torque
.3 to the rated torque value is also greater than 3 times.
.3②The rotor shape of the valve-specific motor is slender. Therefore, the high-speed rotating motor adds a small inertia load to the valve seal when the valve is closed, which can ensure the reliability of the valve sealing surface without damaging the valve sealing surface.
.3 The valve sealing surface will not be damaged.
.3③Since the operation of the valve is an intermittent short-time working system, the working time of the valve special motor is stipulated by the national standard, and some foreign products have a time of .
.3④The end face outlet of the valve-specific motor has no junction box, no fan, self-cooling, and high protection performance. General standard, the highest level is a submersible motor.
