1. First balance the rotor to the maximum precision that can be achieved, and then prepare a removable counterweight block 30~50 times higher than residual unbalance of the rotor (according to the following process: the counterweight block weighs 100 grams, and the residual amount of the rotor should be less than 2-3 grams).Rotor and dynamic balancing machine connection and loading mode unchanged, directly into the following test process.

2. Check whether various devices of the dynamic balancing machine are ok.3. Add a removable counterweight block with known weight to the circumference of 45 degrees of the counterweight designated on either side of the rotor (the following counterweight block weighs 100 as assumed)

G).Start the dynamic balancing machine, the corresponding surface mark value of the dynamic balancing machine should be in 40 -- 50 degrees, 90 -- 110 grams (according to 90% weight removal rate).

4. After stopping the machine, remove the counterweight block and install it on the circumference of the same side of the rotor at an Angle of 135 degrees.Start the dynamic balancing machine, the corresponding surface indicator value of the dynamic balancing machine should be 130 -- 140 degrees, 90 -- 110 grams (according to 90% weight removal rate).

5. After stopping the machine, remove the counterweight block and install it on the 225 degree Angle of the circumference of the same side of the rotor.Start the dynamic balancing machine, the corresponding surface indicator value of the dynamic balancing machine should be in 220-230 degrees, 90-110 grams (according to 90% weight removal rate).

6. After stopping the machine, remove the counterweight block and install it on the circumference of the same side of the rotor at a 315 degree Angle.Start the dynamic balancing machine, the corresponding surface indicator value of the dynamic balancing machine should be in 310-320 degrees, 90-110 grams (by 90% weight removal rate).

7. In the same process, this counterweight block is installed successively at 4 angles around the circumference of the counterweight specified on the other side of the rotor for measurement.

8, if the dynamic balancing machine can reach the above standards, it is considered that the dynamic balancing machine has no fault.

9, if the dynamic balancing machine can approximate to the above standards, it is considered that the dynamic balancing machine is slightly inaccurate calibration problem.This problem usually results in a reduction in operational efficiency without causing major operational errors.If the dynamic balancing machine has slightly inaccurate calibration problem, customers can press the dynamic balancing machine supporting the use of the content in the instructions to eliminate, also can notify the manufacturers to deal with.

10, if the dynamic balancing machine can not meet the above standards, and the deviation is very large, the customer should inform the manufacturer to solve.

11, under special conditions, customers have doubts about the precision or quality of the dynamic balancing machine, can also carry out four-point fault diagnosis of the dynamic balancing machine.Sometimes customers will find that the rotor in the dynamic balancing machine has reached the balance precision, through the above way detection that the dynamic balancing machine is no problem, but the actual installation and operation of the rotor, or a certain degree of vibration, at this time you need to carefully analyze the other reasons for the process.
