無(wú)線振動(dòng)傳感器基礎(chǔ)知識(shí)
Wireless Vibration Sensor Basics
無(wú)線振動(dòng)傳感器測(cè)量振動(dòng)變化并及早檢測(cè)旋轉(zhuǎn)機(jī)器故障以避免故障。許多維護(hù)主管將振動(dòng)傳感器用作其整體狀態(tài)監(jiān)測(cè)程序的一部分。這是因?yàn)榇蠹s 90% 的機(jī)器故障屬于以下四個(gè)主要類別之一：
? 錯(cuò)位
? 不平衡
? 松動(dòng)
? 軸承損壞
合適的無(wú)線振動(dòng)傳感器可以捕捉到這些常見的機(jī)器故障。

A wireless vibration sensor measures vibration changes and detects rotating machine failures early to avoid breakdowns. Many maintenance leaders use vibration sensors as part of their overall condition monitoring program. That’s because some 90 percent of machine faults fall into one of four main categories:
? Misalignment
? Imbalance
? Looseness
? Bearing damage
The right kind of wireless vibration sensors can catch those common machine faults.
A wireless vibration sensor uses a network connection like WiFi, LTE, or ethernet, to continuously transmit measurements to software. For instance, a wireless sensor may send data to computerized maintenance management system (CMMS) software where the data can be stored and analyzed.

振動(dòng)傳感器的工作原理
How a Vibration Sensor Works
無(wú)線振動(dòng)監(jiān)測(cè)傳感器從安裝它的機(jī)器生成振動(dòng)信號(hào)，對(duì)其進(jìn)行轉(zhuǎn)換和處理，然后將實(shí)時(shí)數(shù)據(jù)發(fā)送到 Web 應(yīng)用程序。該資產(chǎn)管理軟件可讓維護(hù)團(tuán)隊(duì)查看和分析數(shù)據(jù)趨勢(shì)，以及執(zhí)行數(shù)據(jù)分析。
通過(guò)無(wú)線振動(dòng)監(jiān)測(cè)，傳感器可以跟蹤和記錄振動(dòng)水平測(cè)量值，用于確定旋轉(zhuǎn)機(jī)械（如壓縮機(jī)和泵（驅(qū)動(dòng)電機(jī)、從動(dòng)裝置）以及皮帶、齒輪、軸、軸承和構(gòu)成機(jī)械系統(tǒng)的其他部件）的健康狀況。
如果無(wú)線振動(dòng)傳感器檢測(cè)到振動(dòng)變化超過(guò)預(yù)定閾值，則會(huì)自動(dòng)觸發(fā)警報(bào)并發(fā)送給維護(hù)團(tuán)隊(duì)成員。根據(jù)資產(chǎn)關(guān)鍵性（即對(duì)整體生產(chǎn)和運(yùn)營(yíng)的影響），決定立即安排維修或更換機(jī)械。
通知可以優(yōu)化維護(hù)計(jì)劃和人工，確保零件可用性，并最終避免資產(chǎn)故障。
A wireless vibration monitoring sensor generates a vibration signal from the machine where it’s mounted, converts and processes it, and then sends the real-time data to a web application. That asset management software lets maintenance teams view and trend data, as well as perform data analysis.
With wireless vibration monitoring, the sensor tracks and records vibration level measurements used to determine the health of rotating machinery such as compressors and pumps (drive motors, driven devices) and belts, gears, shafts, bearings, and other components that make up a mechanical system.
If a wireless vibration sensor detects a change in vibration that exceeds predetermined threshold levels, an alert is triggered automatically and sent to a maintenance team member. Based on the asset criticality, meaning the impact on overall production and operations, a determination is made to immediately schedule a repair or replace the machinery.
The notification enables optimization of maintenance schedules and labor, ensures parts availability, and ultimately avoids asset failure.
測(cè)量振動(dòng)的不同方法
Different Ways to Measure Vibration
振動(dòng)可以用三種不同的方式測(cè)量：位移、速度和加速度。
? 位移是物體從參考點(diǎn)移動(dòng)的距離。它最適合測(cè)量低頻。
? 速度是位移隨時(shí)間的變化率，涵蓋廣泛的頻率范圍。它最適合診斷導(dǎo)致磨損和故障的疲勞力。
? 加速度是速度隨時(shí)間的變化率。它最適合測(cè)量非常高的頻率。
加速度計(jì)是最常見的振動(dòng)傳感器之一，因?yàn)樗鼈儓?jiān)固耐用，并且很容易將加速度轉(zhuǎn)換為速度。
Vibration can be measured in three different ways: displacement, velocity, and acceleration.
? Displacement is the distance an object moves from a reference point. It’s best for measuring low frequencies.
? Velocity is the changing rate of displacement over time and covers a wide range of frequencies. It is best at diagnosing fatigue forces that cause wear and failure.
? Acceleration is the changing rate of velocity over time. It’s best for measuring very high frequencies.
Accelerometers are one of the most common vibration sensors because they’re rugged, and it’s easy to convert the acceleration to velocity.
振動(dòng)傳感器為何如此重要
Why Vibration Sensors Are Important
使用有線和無(wú)線傳感器測(cè)量振動(dòng)變化已成為工業(yè)維護(hù)和可靠性計(jì)劃中必不可少的環(huán)節(jié)。
當(dāng)機(jī)器意外停機(jī)時(shí)，成本可能很高。例如，軸不平衡可能導(dǎo)致聯(lián)軸器損壞，并導(dǎo)致需要更換整個(gè)電機(jī)。
Using wired and wireless sensors to measure vibration changes has become essential in industrial maintenance and reliability programs.
When a machine goes down unexpectedly, the costs can be high. For instance, a shaft imbalance can cause coupling damage and lead to an entire motor needing to be replaced.
測(cè)量振動(dòng)以盡早發(fā)現(xiàn)機(jī)器故障：
Measuring Vibration to Catch Machine Faults Early:
? 降低能源成本
? 減少停機(jī)時(shí)間和人工成本
? 降低維護(hù)和更換成本
? 提高安全性
? Lowers energy costs
? Reduces downtime and labor costs
? Decreases maintenance and replacement costs
? Increases safety
設(shè)置無(wú)線振動(dòng)傳感器
Setting up a Wireless Vibration Sensor
確定適當(dāng)?shù)恼駝?dòng)傳感器設(shè)置、環(huán)境條件和傳感器位置對(duì)于傳感器的正常運(yùn)行至關(guān)重要。根據(jù)安裝類型、機(jī)器類型和軟件，一些振動(dòng)傳感器易于設(shè)置，配置、調(diào)試和安裝后即可立即使用。相比之下，其他振動(dòng)傳感器則更為復(fù)雜，因此咨詢專家通常會(huì)有所幫助。
Determining the proper vibration sensor setup, environmental conditions, and sensor location are critical to a properly functioning sensor. Depending on the type of mount, machine type, and software, some vibration sensors are easy to set up and can be used immediately once configured, commissioned, and installed. In contrast, others are more complex, so it’s often helpful to consult an expert.
選擇合適的無(wú)線振動(dòng)傳感器
Choosing the Right Wireless Vibration Sensor
振動(dòng)傳感器有很多種類型。無(wú)線振動(dòng)監(jiān)測(cè)的選擇通常取決于組織的整體運(yùn)營(yíng)能力。機(jī)器或部件對(duì)生產(chǎn)的重要性以及應(yīng)用將有助于確定需要哪種無(wú)線振動(dòng)傳感器。
例如，篩選傳感器通常安裝在半關(guān)鍵和其他重要機(jī)器上。它提供讀數(shù)以指示存在問(wèn)題，并讓用戶知道機(jī)器是否需要檢查或維護(hù)。
分析振動(dòng)傳感器通常用于更關(guān)鍵的資產(chǎn)。這些傳感器具有加速度計(jì)，可幫助測(cè)量數(shù)據(jù)中看到的幅度和模式的變化。需要高分辨率傳感器來(lái)提供分析所需數(shù)據(jù)的詳細(xì)信息。
There are a number of different types of vibration sensors. Wireless vibration monitoring choices usually depend on an organization’s overall operational capacity. How critical a machine or component is to production and the application will help determine which wireless vibration sensor is needed.
For instance, a screening sensor is usually mounted on semi-critical and other essential machinery. It provides readings to indicate a problem exists and lets users know if the machine needs to be inspected or maintained.
An analysis vibration sensor is generally used on more critical assets. These sensors have accelerometers that help measure changes in amplitude and patterns seen in the data. A high-resolution sensor is needed to provide the detail of the necessary data for analysis.
傳感器的設(shè)計(jì)、尺寸和范圍多種多樣，因此非常靈活。了解期望測(cè)量的數(shù)據(jù)特征以及任何環(huán)境限制有助于確定哪種傳感器最適合預(yù)期用途。
There are many designs, sizes, and ranges of sensors to choose from, making them highly flexible. Understanding the data characteristics you expect to measure, and any environmental constraints can help decide which one fits the intended use best.
