英國GRIMM格林進口臥式化工屏蔽泵軸承檢測原理：
屏蔽泵的運用在現今社會越來越廣泛。而其造價高，使用環境及其苛刻，為保證屏蔽泵正常工作，其維護成為企業一項必不可少的工作。屏蔽泵中有一個核心部件—軸承，長期使用后會因磨損較大而影響正常使用。通過示波器我們能夠看出其是否正常。
下面介紹一下屏蔽泵軸承檢測原理：
在定子鐵心槽口處繞制一對軸承檢測線圈，當轉子旋轉時便感應出溝形高次諧波重迭波形的電壓。各線圈的相位差是180°時，在軸承工作時，基波為零，在軸承檢測線圈輸出端只顯示溝形高次諧波的A、B線圈諧波之差。該溝形高次諧波，在軸承磨損后間隙a大，間隙b小時，B線圈的溝形高次諧波顯著增加，其結果發生跟軸承磨損量成比例的輸出電壓。通過表示測出的電壓，將運轉情況反映給操作者。

UK GRIMMImported horizontal chemical shielding pumpbearing 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.
