Embodiment Construction

[0021] see figure 1 , a high-speed dynamic balancing method for an assembled compressor rotor provided by an embodiment of the present invention includes:

[0022] Step 1: Carry out low-speed dynamic balance on rotor 1, and confirm the initial low-speed dynamic balance value and phase.

[0023] Step 2, assembling the high-speed dynamic balancing mechanism 4 on the gear shaft 2 and the first-stage impeller 3 of the rotor 1 .

[0024] Step 3, the rotor 1 drives the high-speed dynamic balancing mechanism 4 to perform low-speed dynamic balancing again, so that the value and phase return to the initial state of the rotor 1, and the unbalanced amount is removed on the high-speed dynamic balancing mechanism 4, that is, in the high-speed dynamic balancing mechanism The non-fitting end face of the machine is cut to remove weight.

[0025] Step 4: Perform high-speed dynamic balancing through the rotor 1, turn the high-speed dynamic balancing mechanism 4 180° during the high-speed dyna...

Description

technical field [0001] The invention relates to the technical field of rotor dynamic balancing, in particular to a high-speed dynamic balancing method and device for an assembled compressor rotor. Background technique [0002] Rotor dynamic balance is an important means to adjust and correct the unbalanced force and moment generated when the rotor of a rotating machine rotates. For flexible rotors, after the rotor exceeds the critical speed, the unbalance will cause obvious deformation of the rotor. Therefore, for flexible rotors, using high-speed dynamic balancing at the same speed as the unit is running is the best technical means to test the rotor balancing effect. Packed compressors are widely used due to their compact structure, small footprint, isothermal compression, and high efficiency. The rotor is a flexible rotor, but because the driving form of the rotor in the unit is different from that of the high-speed dynamic balancing machine, domestic and foreign manufact...
