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, drive the high-speed dynamic balancing mechanism 4 through the rotor 1 to restore the low-speed dynamic balance value and phase to the initial state of the rotor 1, and remove the unbalanced amount on the high-speed dynamic balancing mechanism 4, that is, in the high-speed dynamic balancing mechanism. Cooperate with the end face for cutting and weight removal.

[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 dynamic balancing process, an...

The high-speed dynamic balancing method and apparatus of the assembly type compressor rotor effectively improve the rotor balance precision, the first-order critical rotation speed of the rotor is simple, and high-speed balancing can be carried out.

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...
