產品描述:A6500-UM 軸相對振動模式
軸相對振動模式用于提供給工廠中最關鍵旋轉設備以提高可靠性。該功能與基它CS1 A500 ATG監(jiān)測模塊配合使用時，可形成一個完整的AP1670機械保護監(jiān)測系統(tǒng)。其應用包括汽輪機、燃氣輪機、壓縮機和水輪機。軸相對振動測量的主要功能是通過被測量參數與報警設定值進行比較，驅動報警和繼電器輸出，從而準確監(jiān)測軸相對振動并以可靠的方式保護設備,軸相對振動包括一個穿過軸承殼體安裝或安裝在軸承內部以旋轉軸或監(jiān)測目標安裝在軸承外殼上以旋轉軸作為監(jiān)測目標的位移傳感器位移傳感器是一種非接觸式傳感器，用于測量抽的位置和運動。由于該位移傳感器安裝在軸承上，監(jiān)測的參數被稱為軸相對振動，也就是抽相對于軸承殼體的振動。
油相對振動是所有滑動軸承機器上用于預測和保護監(jiān)測的重要測量指標，當機殼重量遠大于轉子，且預計軸承殼體不會在0~正常運轉轉速之間振動時，應選擇相對振動。當軸承殼體和轉子質量接近于相等時，若軸承殼體更可能振動且影響軸相對振動讀數，則有時會選擇軸絕對振動測量。

Product Description :A6500-UM shaft relative vibration mode
The shaft relative vibration mode is used to improve reliability for the most critical rotating equipment in the plant. This function, when combined with the base CS1 A500 ATG monitoring module, forms a complete AP1670 mechanical protection monitoring system. Applications include steam turbines, gas turbines, compressors and water turbines. The main function of shaft relative vibration measurement is to drive the alarm and relay output by comparing the measured parameter with the alarm setting value. To accurately monitor the relative vibration of the shaft and protect the equipment in a reliable manner, the relative vibration of the shaft includes a displacement sensor mounted through the bearing housing or mounted inside the bearing to rotate the shaft or monitor the target mounted on the bearing housing to monitor the rotating shaft The Displacement sensor is a non-contact sensor used to measure the position and movement of the pump. Since the displacement sensor is mounted on the bearing, the monitored parameter is called shaft relative vibration, that is, vibration relative to the bearing housing.
Oil relative vibration is an important measurement index for prediction and protection monitoring on all plain bearing machines. When the weight of the housing is much greater than that of the rotor, and the bearing housing is not expected to vibrate between 0 and normal running speed, relative vibration should be selected. When the bearing housing and rotor masses are close to equal, the absolute shaft vibration measurement is sometimes chosen if the bearing housing is more likely to vibrate and affect the relative shaft vibration reading.
