汽輪機(jī)振動(dòng)速度傳感器是用于測(cè)量汽輪機(jī)振動(dòng)速度的傳感器。9200-06-01-10-00可以測(cè)量汽輪機(jī)軸的絕對(duì)振動(dòng)速度,并將其轉(zhuǎn)換為電信號(hào),以供控制系統(tǒng)使用。
汽輪機(jī)振動(dòng)速度傳感器通常采用磁電感應(yīng)原理,利用磁路系統(tǒng)、慣性質(zhì)量、彈簧尼等部分組成。在工作時(shí),將傳感器安裝在機(jī)器上,在機(jī)器振動(dòng)時(shí),在傳感器工作頻率范圍內(nèi),線圈與磁鐵相對(duì)運(yùn)動(dòng)、切割磁力線,在線圈內(nèi)產(chǎn)生感應(yīng)電壓,該電壓值正比于振動(dòng)速度值。
汽輪機(jī)振動(dòng)速度傳感器具有以下特點(diǎn):
輸出信號(hào)和振動(dòng)速度成正比,可以兼顧各個(gè)頻率段的振動(dòng)測(cè)量領(lǐng)域。
傳感器設(shè)計(jì)中取消了有摩擦的活動(dòng)元件,因此靈活性好,可以測(cè)量微小的振動(dòng)(0.01mm)。
傳感器有一定的抗橫向振動(dòng)能力(不大于10g峰值)。
外殼采用不銹鋼殼體激光焊接工藝,防護(hù)等級(jí)可達(dá) IP65,防止生銹。
在使用汽輪機(jī)振動(dòng)速度傳感器時(shí),需要注意以下幾點(diǎn):
傳感器的安裝位置應(yīng)選擇在靠近軸承箱或底座的支撐位置上,以獲得更好的測(cè)量效果。
在安裝傳感器之前,應(yīng)先測(cè)量汽輪機(jī)的振動(dòng)速度,并確定測(cè)量位置和測(cè)量方向。
在使用過程中,應(yīng)定期對(duì)傳感器進(jìn)行檢查和維護(hù),以確保其正常工作和長(zhǎng)期穩(wěn)定性。
傳感器應(yīng)與控制系統(tǒng)連接,以便將測(cè)量數(shù)據(jù)傳輸?shù)娇刂葡到y(tǒng)進(jìn)行分析和處理。
總之,9200-06-01-10-00 汽輪機(jī)振動(dòng)速度傳感器是測(cè)量汽輪機(jī)振動(dòng)速度的重要工具,具有測(cè)量準(zhǔn)確、穩(wěn)定性好、可靠性高等優(yōu)點(diǎn)。它可以為汽輪機(jī)的安全運(yùn)行和故障診斷提供重要依據(jù)。

Turbine vibration speed sensor is used to measure turbine vibration speed sensor. The 9200-06-01-10-00 measures the absolute vibration speed of the turbine shaft and converts it into an electrical signal for use by the control system.
Turbine vibration velocity sensor usually adopts the principle of magnetoelectric induction, which is composed of magnetic circuit system, inertial mass, spring Ni and so on. When working, the sensor is installed on the machine, when the machine vibrates, in the sensor operating frequency range, the coil and the magnet relative movement, cutting the magnetic field line, the induction voltage in the coil, the voltage value is proportional to the vibration speed value.
Turbine vibration speed sensor has the following characteristics:
The output signal is proportional to the vibration speed, which can take into account the vibration measurement fields of various frequency segments.
The sensor design eliminates the friction of moving elements, so it is flexible and can measure small vibrations (0.01mm).
The sensor has a certain resistance to transverse vibration (no more than 10g peak).
The shell adopts the laser welding process of stainless steel shell, and the protection grade can reach IP65 to prevent rust.
When using the turbine vibration speed sensor, the following points need to be noted:
The installation position of the sensor should be selected in the support position near the bearing box or base to obtain better measurement results.
Before installing the sensor, the vibration speed of the turbine should be measured, and the measurement position and measurement direction should be determined.
During use, the sensor should be checked and maintained regularly to ensure its normal operation and long-term stability.
The sensor shall be connected to the control system in order to transmit the measurement data to the control system for analysis and processing.
In short, the 9200-06-01-10-00 turbine vibration speed sensor is an important tool for measuring turbine vibration speed, which has the advantages of accurate measurement, good stability and high reliability. It can provide important basis for the safe operation and fault diagnosis of steam turbine.
