本特利振动监测培训教程，本教程的主要内容：位移传感器噪声源
 
　　噪声是一种你不需要的信号，但多数情况下，在测量过程中，噪声是无法避免的。尽管在测量过程中无法除噪声，但可以将噪声降低到Z小程度，使其不影响你对信号的分析。要做到这一点，就要了解噪声的来源和特征。噪声是一种不合乎需要的信号成分，它可以歪曲数据，妨碍你从数据中提取机器状态信息的能力，包含的信息与机器的状态无关。噪声可以从测量系统的一个环节引入振动信号，但系统各个部分对噪声的敏感程度不同。本特利位移传感器包括bently3300系列的涡流传感器探头。

　　位移传感器噪声源Crankcase vibration: a vibration speed sensor is arranged on the horizontal axis of each main bearing between two cylinder rows of the reciprocating compressor crankcase to measure the crankcase body vibration. Bentley 330500 series Velomitor piezoelectric vibration speed sensor is used when the working speed of the reciprocating compressor is higher than 500 rpm; Bentley 190501VelomitorCT piezoelectric vibration speed sensor is used when the working speed is lower than 500rpm.



Crosshead vibration: redundant acceleration sensors are configured on the vertical plane at the midpoint of crosshead movement of each cylinder of the reciprocating compressor to monitor the impact event of reciprocating components; Bentley 330425 acceleration sensor is used for measurement.



Piston rod position: a pair of mutually perpendicular piston rod position measuring points shall be configured in the horizontal and vertical directions of each cylinder of the reciprocating compressor perpendicular to the piston rod plane; Bentley 3300XL series eddy current sensor is used for measurement. For reciprocating compression piston rod measurement.



Cylinder dynamic pressure: each cylinder of the reciprocating compressor is equipped with two cylinder pressure measuring points (suction and exhaust), which are measured by Bentley 165855 cylinder pressure sensor.



Bearing vibration: each main bearing in the crankcase of the reciprocating compressor is equipped with a speed sensor to measure the bearing vibration. Bentley 330500 series Velomitor piezoelectric vibration speed sensor is used when the working speed of the reciprocating compressor is higher than 500 rpm; Bentley 190501VelomitorCT piezoelectric vibration speed sensor is used when the working speed is lower than 500rpm.



Bearing temperature: each main bearing is equipped with a temperature sensor to measure the bearing temperature.



Air valve temperature: each air valve (suction valve and exhaust valve) of the reciprocating compressor cylinder is equipped with a temperature measuring valve temperature.



Gearbox shell vibration (if applicable): a pair of X/Y direction shell vibration measuring points shall be provided at the support bearings of input and output shafts of each gearbox; Bentley 330400 series piezoelectric vibration acceleration sensor is used for measurement.



Motor pad vibration: each rolling support bearing is equipped with two pad vibration measuring points (installed horizontally and vertically), which are measured by Bentley 330500 series Velomitor piezoelectric vibration velocity sensor.
