英国GRIMM格林进口卧式化工屏蔽泵轴承检测原理：
            屏蔽泵的运用在现今社会越来越广泛。而其造价高，使用环境及其苛刻，为保证屏蔽泵正常工作，其维护成为企业一项必不可少的工作。屏蔽泵中有一个核心部件—轴承，长期使用后会因磨损较大而影响正常使用。通过示波器我们能够看出其是否正常。
下面介绍一下屏蔽泵轴承检测原理：
在定子铁心槽口处绕制一对轴承检测线圈，当转子旋转时便感应出沟形高次谐波重迭波形的电压。各线圈的相位差是180°时，在轴承工作时，基波为零，在轴承检测线圈输出端只显示沟形高次谐波的A、B线圈谐波之差。该沟形高次谐波，在轴承磨损后间隙a大，间隙b小时，B线圈的沟形高次谐波显著增加，其结果发生跟轴承磨损量成比例的输出电压。通过表示测出的电压，将运转情况反映给操作者。

UK GRIMM imported horizontal chemical shielding pump bearing detection principle :

 

 

 

          The application of canned motor pump is more and more widespread in modern society. And its high cost, the use of the environment and its harsh, in order to ensure the normal work of shielding pumps, its maintenance has become an essential job of enterprises. Shield pump has a core component - Bearings, after long-term use will be affected by the wear and tear of the normal use. Through the oscilloscope, we can see whether it is normal or not.

The following describes the principles of canned pump bearings detection:

A pair of bearing detecting coils are wound around the stator core notch, and the voltage of the groove shaped superimposed harmonic waveform is induced when the rotor rotates. When the phase difference of each coil is 180 degrees, when the bearing is working, the fundamental wave is zero, and the output of the bearing detecting coil only shows the difference of the harmonic of the A and B coils of the groove type harmonic. When the groove is high, the gap a is large after the bearing is worn, and the gap is B hours. The groove type harmonic of the B coil increases remarkably, and the output voltage is proportional to the wear amount of the bearing. The operation is reflected to the operator by means of indicated voltage.
