1、动平衡程序929风机转子动平衡校验程序一、找平衡前：A. Before searching balance:1.确定要找平衡转子叶轮的宽径比（B/D），确定转子的平衡校正方式（采用单面平衡或是双面平衡。对于单面平衡，转子可以不旋转，用作图法可以进行计算，确定加减的质量；对于双面平衡，则需要在平衡机上进行旋转，确定加减质量及相位）。1.Determine the breadth diameter ratio (B/D) of the impeller of rotor to search balance, and the balance correcting way for rotor (inc

2、luding single-plane balance and double-plane balance. For single - plane balance, the rotor doesnt rotate, the mass of add and subtraction can be calculated by the graphing method; for double-plane balance, the rotor must be rotated on the balancing machine to determine the mass of add and subtracti

3、on and phase). 2.了解该转子的平衡精度及工作转速，如G6.3，3000r/min等，以便求出转子的总允许剩余不平衡量。2.Get the balance quality and working speed of the rotor, such as G6.3，3000r/min all the like, thus to calculate the total allowable residual unbalance .3.了解转子的支撑方式（6种支撑方式），以便将总允许剩余不平衡量向校正面分配，得到每个平面可允许剩余不平衡量即该平面的平衡允差（，）。3. Get the su

5、平衡量要减少2/3）。4. Calculate the percentage of the rotor mass to the total mass of the machine, so as to make sure whether the balance quality is reduced or not (If the percentage of a light rotor is around 1/10, the allowable unbalance value can be 3 times as more as that of this level; while the percen

6、tage of a very heavy rotor is above 1/2, the allowable unbalance value will be reduced by 2/3). 5.按照转子联轴器尺寸及平衡机联轴节尺寸加工制作专用联接盘。（注：联接盘与转子联轴器之间的螺栓联接应按圆周均布。）安装时，应将螺杆由联接盘侧向转子侧穿过，以避免因为螺杆过长，影响平衡校验。）5. The special connection plate can be processed based on the size of the coupler of the rotor and the coupli

7、ng of the balance machine. (Note: The bolt connection between the connection plate and the coupler shall be placed evenly in circle.) When installing, pass the screws through the rotor side from the connection plate side, to avoid influence on the balance correcting due to the overlong screws. 6.根据转

8、子类型确定支撑面和校正面，测量相关尺寸：1).转子两个支撑点A、B处轴颈的直径；2）联接盘左侧端面到转子左支撑的距离L；3). 转子两个支撑点之间的距离M；注意：这里有六种支撑方式6. Determine the support side and the correcting side according to the rotor type, and measure related sizes: 1). 2 support points of the rotor: the diameters of A and B journals; 2) Distance L between the left

9、 side end face of the connection plate and the left support of the rotor; 3) Distance M between the 2 support points; Note: there are 6 support modes in total. 7.根据转子两支撑点A、B支撑轴径，调整平衡机两个支架上支撑轴承的高度，选择合适的滚轮板（大轴用小轮，小轴用大轮）；根据测量尺寸L、M调整平衡机两个支架在滑轨上的位置。7. Based on A and B journal diameters of the rotor, adju

10、st the height of axial bearings of two supports on the balance machine, and select appropriate roller plate ( using a small wheel for the big shaft, and a big wheel for the small shaft); adjust the position of two supports on the slide track.8.在转子上装上相应的连接法兰；擦干净滚轮上的污垢，加上润滑油；将转子吊装到平衡机上与万向节连接，并关上万向节的安全

11、罩。8. Install the related connecting flange on the rotor; clear up the dirt on the roller, and give lubricating oil; hoist and install the rotor on the balance machine and connect it with the cardan joint, close the safety shield of the cardan joint.9.检查机组所有锁紧部件紧固可靠后，打开平衡机控制柜电源。9. Check if the lock p

Conduct measurement of the unbalance value after starting up. (Note: during the rotating process, there shall be no bystanders and no articles on the

13、two sides of the rotor, such as tooling, rag, etc.)转子平衡校验第一次开机前，应将控制柜上“转速调节旋钮”向左旋转至较低转速位置。确认转子两侧没有人和障碍物后，按启动按钮开机。When the machine is started up for correcting for the first time, please turn the “rotating speed regulation button” on the control cabinet to the left until the slow speed of revolution.

14、 After ensuring no person and barrier on the two sides of the rotor, start the machine up. i.如果转子运转比较平稳，可慢慢向右旋转“转速调节旋钮”增加转速，至设置转速（如300转/分）附近停止加速。等转子运行平稳后，机组测量并自动显示出测量值。测量值相对稳定后，按HOLD键保持读出并停机；i. If the rotor rotates smoothly, turn “rotating speed regulation button” to the right slowly to increase the

15、 rotating speed, until the desired speed (such as 300 rpm) obtained. After the rotor runs smoothly, the unit starts to measure and display the measurement value. After the value turns to be stable relatively, press HOLD to maintain the value, and read it and stop the machine; ii.如果转子振动比较剧烈，应立即停机。将“平

16、衡速度”设置到较低转速后进行预校验；ii. If the rotor vibrates heavily, please stop the machine immediately. After the “balance speed” is set to the lower rotating speed, conduct pre-correcting; 转子在预设的“平衡速度”校验过后，不必再调整“转速调节旋钮”。直接按启动按钮开机，待测量值相对稳定后，按HOLD键保持读出并停机；After the preset “balance speed” is corrected, directly sta

17、rt the machine up without readjusting the “rotating speed regulation button”. After the value turns to be stable relatively, press HOLD to maintain the value, and read it and stop the machine;注意：在设定转子转速时，要注意电机的转速不能超过转子设定的额定转速。否则系统将启动保护。Note: when setting the rotating speed of the rotor, note that th

Removing balance value转子停稳后，对照显示的相位角找到转子左右校正面上对应位置，并做好记号；After the rotor stops steadily, find out the corresponding positions on the left and right correcting side according to the displayed phase angle

19、, and make marks; 按预设的校正方式（加重或去重）对转子进行校正；Correct the rotor in the preset correcting mode (Add Weight or Remove Weight);i.加重：可以进行平衡块的调整，也可以取对应质量的配重块焊接到校正面上（校准面允许焊接配重块）；i. Add Weight: you can adjust the balance weight or solder the counter weight of corresponding mass to the correcting side (the count

20、er weight is allowed to solder on the correcting side); 注意：平衡校正焊接时，最好去除传感器连线或关机，或卸下转子后，再进行焊接。Note: After correcting soldering, it is suggested to remove the sensor cables or power the machine off, or re-solder after removing the rotor.ii.去重：一般选用打磨校准面的方式进行校正；ii. Remove Weight: Conduct correcting in t

If the measurement result doesnt meet the requirement, conduct re-correcting following the st

22、ep 8, until it meets the requirement.注意：校正的标准以转子总允许剩余不平衡量分配到两个校正面的可允许剩余不平衡量即该平面的平衡允差（，）为标准，确定精确到多少mg以内。Note: the correcting standard is that of the two correction planes allowable residual unbalance, namely the balance tolerances of this plane（，）distributed from the total allowable residual unbalanc
