What is the meaning of single speed, double speed, and frequency conversion speed of crane operation?
Very simple say! 1, the speed of a crane is only one speed 2. Crane running double speed is refers to has a faster speed, and a slower speed, the speed of the two is driven by two different motor, with a slow speed motor and a fast The variable speed regulation is by changing the frequency of the power supply of the input motor, so that the motor has different speed, which makes the crane have a change of speed I don't know if you know,
The speed of the speed of the crane, the speed of the speed of the crane, the speed of the variable speed is: A crane running single speed means that there is only one running speed. Crane running double speed is refers to a faster running speed, there will be a slower speed, speed of the two is driven by two different motor, with a slow speed motor and a fast. Crane operation frequency control of motor speed is by changing the frequency of the input motor power, so that the motor has different speed, thus make the crane has the speed of change.
It's the speed change of the crane Single speed and double speed through the crane machine speed, that is to change the winding connection mode make the circuit produces the crane electric pole logarithm change, realize the speed control, in general there are 3000 turn, 1500, 1000, etc And the variable speed regulation, like the name, is by changing the frequency of the power supply of the input motor, the voltage to adjust the speed of the crane
