首先要確認轉(zhuǎn)子設備是否存在不平衡引起振動?，F(xiàn)場設備的振動是復雜的，一般混頻振動。只有在不平衡振動分量占混頻總振動量的80%以上，使用本儀器才能看到效果。具體說運用本儀器的“信號分析"里“FFT分析"功能，對振動信號進行頻譜分析。通過頻譜分析，如果基頻的振動量很大，其他倍頻振動量都很小，甚至沒有。運用本儀器的操作就能達到令人滿意的效果。</span></span></p><p><span

style="font-size:12pt"><span style="font-family:宋體">①</span></span><span style="font-size:12pt"><span style="font-family:宋體">在工作轉(zhuǎn)速范圍內(nèi)，能夠進行多次啟停機運轉(zhuǎn)。具體說用試重法，對單面平衡至少需要開3次機，對雙面平衡至少需要開4次機，才能看到動平衡的效果。</span></span><span style="font-size:12pt"><span style="font-family:宋體">②</span></span><span style="font-size:12pt"><span style="font-family:宋體">能夠便利在現(xiàn)場對轉(zhuǎn)子進行加重或去重工作。一切密封的旋轉(zhuǎn)轉(zhuǎn)子或軸系或不允許在轉(zhuǎn)子校正平面上加重或去重，是無法進行動平衡操作。</span></span><span style="font-size:12pt"><span style="font-family:宋體">③</span></span><span style="font-size:12pt"><span style="font-family:宋體">現(xiàn)場能方便安裝傳感器，單面平衡需求一個轉(zhuǎn)速傳感器和一個振動傳感器，雙面平衡需求一個轉(zhuǎn)速傳感器和二個振動傳感器。這些是動平衡儀測量的先決條件。</span></span></p><p><span style="font-size:12pt"><span style="font-family:宋體">6.3、如何提高動平衡儀測量精度</span></span></p><p><span style="font-size:12pt"><span style="font-family:宋體">動平衡儀不同于動平衡機。動平衡機既有電控部分，又有支撐轉(zhuǎn)子運轉(zhuǎn)的機械部分。動平衡儀只有電控部分，其支撐轉(zhuǎn)子運轉(zhuǎn)的機械部分是由各家用戶提供的；現(xiàn)場有進口設備；有國產(chǎn)設備；有各廠自己生產(chǎn)的設備；有臨時焊接的設備，各種設備機械加工的精度各不相同，差別很大。另外現(xiàn)場測試環(huán)境也是不同的有的干擾大，有的干擾小。這就造成平衡儀到各廠家測量精度的不同，無法給出一個統(tǒng)一的測量精度標準。在本儀器中只有一個技術指標，不平衡量減少率≥８5％，這個指標也是比較籠統(tǒng)的。在進口設備；國產(chǎn)設備中能夠達到這個指標，對各廠自己生產(chǎn)的設備只能接近這個指標，對現(xiàn)場臨時焊接的設備則是很難達這個指標。總之動平衡儀測量精度取決于支撐轉(zhuǎn)子運轉(zhuǎn)的設備的精度等級，設備的精度等級越高，動平衡儀測量精度也越高。用我單位動平衡儀，用動平衡機的機械部分，同樣可以達到動平衡機的技術指示，這毫無疑義的。</span></span></p><p><span style="font-size:12pt"><span style="font-family:宋體">6.4、動平衡儀與動平衡機的區(qū)別</span></span></p><p><span style="font-size:12pt"><span style="font-family:宋體">現(xiàn)場動平衡儀的優(yōu)點：</span></span><span style="font-size:12pt"><span style="font-family:宋體">①</span></span><span style="font-size:12pt"><span style="font-family:宋體">現(xiàn)場平衡是在*裝配好的機器上進行的，可以補償裝配上的誤差。</span></span><span

style="font-family:宋體">使用霍爾轉(zhuǎn)速傳感器，需要配套小磁鋼作為標志。小磁鋼本身是一個質(zhì)量塊，有一定附加質(zhì)量，對平衡精度要求高的用戶是不容許的。解決的方法是在同半徑對面的位置（相差180</span></span><span style="font-size:12pt"><span style="font-family:宋體">°</span></span><span style="font-size:12pt"><span style="font-family:宋體">位置），反貼一個同樣的小磁鋼。正貼小磁鋼測轉(zhuǎn)速，反貼小磁鋼抵消附加質(zhì)量。另外安放小磁鋼半徑盡量小一點也可以減少小磁鋼附加質(zhì)量的影響。</span></span></p><p><span style="font-size:12pt"><span

style="font-family:宋體">傳感器數(shù)值穩(wěn)定，包括轉(zhuǎn)速數(shù)值穩(wěn)定和振動數(shù)值穩(wěn)定。使用霍爾轉(zhuǎn)速傳感器或激光轉(zhuǎn)速傳感器數(shù)值的穩(wěn)定是很容易。使用光電轉(zhuǎn)速傳感器數(shù)值不穩(wěn)定，需要重新做光電標志，調(diào)節(jié)光電傳感器與光標紙的距離以及傳感器上靈敏度旋鈕。另外還要注意每次設備開機，轉(zhuǎn)速測量值要基本*，變化值在10轉(zhuǎn)以內(nèi)。振動傳感器測量數(shù)值不穩(wěn)定。解決的方法是：</span></span><span

style="font-family:宋體">試重法動平衡工作需要試加重，根據(jù)加重前后的振動變化計算出應加重量與相角。試重塊重量大小的選擇很重要。試重塊重量重了，有可能導致機器振動過大，損壞設備。試重塊重量輕了，加重前后的振動變化不大，計算出誤差較大。試加重大小可以按加重產(chǎn)生的離心力近似等于1%轉(zhuǎn)子重量的原則來確定。推薦方法是：在上述原則中，取試加重重量可以偏輕一些。無論單面或雙面平衡，首先記錄初始振動的幅值和相角，然后記錄加重后振動的幅值和相角。比較前后二次振動的幅值和相角的變化，當幅值大于</span></span><span style="font-size:12pt"><span style="font-family:宋體">±</span></span><span style="font-size:12pt"><span style="font-family:宋體">20%變化，相角大于</span></span><span style="font-size:12pt"><span

style="font-family:宋體">變化，就認為試重塊重量是合適。如果振幅變化不明顯，就應加大試重的重量。如果相位變化不明顯，就應重新移動試重的位置。上述所說是針對著*個轉(zhuǎn)子選取試重重量方法，對于同樣尺寸；同樣大小第二個轉(zhuǎn)子只要取*個轉(zhuǎn)子巳經(jīng)計算出來轉(zhuǎn)子上存在的不平衡量作為試重塊大小就可以。</span></span></p><p><span

style="font-family:宋體">對同一轉(zhuǎn)子或同一外形尺寸、材料及結(jié)構(gòu)的轉(zhuǎn)子，可以認為其影響系數(shù)是不變的。因此，為提高生產(chǎn)效率，對同一轉(zhuǎn)子或同一外形尺寸、材料及結(jié)構(gòu)的轉(zhuǎn)子，在使用試重法求得了其影響系數(shù)后，就可以使用影響系數(shù)法對這些轉(zhuǎn)子進行平衡。使用影響系數(shù)法進行平衡省去了加試重的步驟。對*個轉(zhuǎn)子（新轉(zhuǎn)子）必須用試重法做動平衡，對于同樣尺寸；同樣大小第二個轉(zhuǎn)子（老轉(zhuǎn)子）可以用影響系數(shù)法做動平衡，前提是手邊有通過使用試重法求得了其轉(zhuǎn)子影響系數(shù)記錄。試重法適用于大型的單件的轉(zhuǎn)子做動平衡。影響系數(shù)法適用于小型的多批量的轉(zhuǎn)子做動平衡。</span></span></p><p><span
