What type of balancing should be performed on the rotor, and what is the basis for this?
Perform static balance on each individual piece, and then perform dynamic balance after it is assembled into a rotor. There are standards, industry standards – **all standards have regulations. Failing to perform balanced vibration will result in exceeding the limits.
Should static balance be done first, and then dynamic balance?
Rotors are balanced before leaving the factory. Whether balance adjustment needs to be done on-site or back at the factory using a balancing machine depends on whether disassembly and assembly are convenient and on the conditions available on site. Whether low-speed or high-speed balancing is required is determined by the relationship between the operating speed and the critical speed; rotors that operate at high speeds need both low-speed and high-speed balancing. As for whether single-sided or double-sided balancing is necessary, it depends on the ratio of the rotor’s length to its radius – narrower rotors can often be balanced on a single side, a process known as static balancing, while wider rotors require double-sided balancing, also known as dynamic balancing.
It is necessary to check for balance not only during assembly, but also periodically after operation due to wear.
Static balance of the rotor must be achieved, while whether dynamic balance is required depends on relevant standards. Let’s take a look at a place in Kaichuan. http://bbs.hcbbs.com/archiver/tid-142150.html
