產(chǎn)品描述:A6500-UM 軸相對(duì)振動(dòng)模式
軸相對(duì)振動(dòng)模式用于提供給工廠中最關(guān)鍵旋轉(zhuǎn)設(shè)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(shí)，可形成一個(gè)完整的AP1670機(jī)械保護(hù)監(jiān)測系統(tǒng)。其應(yīng)用包括汽輪機(jī)、燃?xì)廨啓C(jī)、壓縮機(jī)和水輪機(jī)。軸相對(duì)振動(dòng)測量的主要功能是通過被測量參數(shù)與報(bào)警設(shè)定值進(jìn)行比較，驅(qū)動(dòng)報(bào)警和繼電器輸出，從而準(zhǔn)確監(jiān)測軸相對(duì)振動(dòng)并以可靠的方式保護(hù)設(shè)備,軸相對(duì)振動(dòng)包括一個(gè)穿過軸承殼體安裝或安裝在軸承內(nèi)部以旋轉(zhuǎn)軸或監(jiān)測目標(biāo)安裝在軸承外殼上以旋轉(zhuǎn)軸作為監(jiān)測目標(biāo)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(yùn)動(dòng)。由于該位移傳感器安裝在軸承上，監(jiān)測的參數(shù)被稱為軸相對(duì)振動(dòng)，也就是抽相對(duì)于軸承殼體的振動(dòng)。

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.
