Valve specific motor performance:
① The torque of the valve motor conforms to the opening and closing torque characteristics of the valve
Generally, the torque required for opening and closing the valve in place in a short time is high, In the intermediate operation state, the required torque value is only 1 / of the maximum torque value of opening or closing; 3 , Therefore, the special motor for valve is characterized by high starting torque, Strong overload capacity
The ratio of the maximum torque to the rated torque of the valve specific motor is greater than 3 Times, The ratio of starting torque to rated torque is also greater than nbsp & 3; Times
② The special motor for valve is designed with slender rotor shape
Therefore, the inertia load added to the valve seal by the high-speed motor when the valve is closed is small, It can ensure the reliable sealing surface of the valve, It will not damage the sealing surface of the valve
③ Since the operation of the valve is intermittent short-time working system, Therefore, the working time of the special motor for the valve is 10min , The time of some foreign products is 15min
④ End face outgoing line of special motor for valve, No junction box, No fan, Self cooling, High protection performance
General system IP54 , ip66 , * Senior grade IP68 Submersible motor
