Centering method for rotor assembly during multistage rotor assembly

One of the most important issues in assembly is to check that the center of the impeller exit and the center of the guide (deflector) are the same, that is, each impeller exit center must be aligned with the center of the guide wing. Adjusting the "center of consistency" not only ensures the normal efficiency of the pump, but also to prevent the rotation, or impeller and other hazards before and after touch. The center of the "center" is mainly determined by the position of the balance disc....

difference between servo motor and stepper motor

A stepper motor is an actuator that converts a digital pulse signal into an angular displacement. That is, when the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle (ie, step angle, step angle) in the set direction. You can control the angular displacement by controlling the number of pulses to achieve accurate positioning. At the same time, you can control the speed and acceleration of the motor by controlling the pulse frequency to achieve the...
