Operators can also draw on their own experience when assessing the status of the machine. Long-term observation of the characteristic values and the machine's history can provide relevant values based on experience.
The limits ascertained from this can vary significantly from limits set by norms and those prescribed by the manufacturer of the machines. This assessment is only possible when operators have considerable experience with oscillations in the machine and are in a position to differentiate between positive and negative characteristics.
操作员在评估机器的状态时,也可以借鉴自己的经验。对特征值的长期观察和机器的历史可以提供基于经验的相关值。
由此确定的极限值可能与规范规定的极限值和机器制造商规定的极限值有很大差异。只有当操作员对机器的振荡有相当的经验,并且能够区分积极和消极的特性时,这种评估才有可能。
When determining limit values, it is important to note that vibration measurements are influenced by factors such as:
在确定极限值时,必须注意到振动测量受以下因素的影响:
•The location of the damage
损坏的位置
•The location of the sensor
传感器的位置
•The speed of the moving parts of the machine
机器的运动部件的速度
•The load on the machine parts
机器部件上的负载
