style="font-size:14px;">變頻器那種好,認準(zhǔn)云南永樂科技有限公司，專業(yè)從事變頻器生產(chǎn)銷售,改造,維修與產(chǎn)品調(diào)試等服務(wù),產(chǎn)品型號齊全,質(zhì)量可靠,響應(yīng)快運行穩(wěn)定。變頻器還可以普遍應(yīng)用于傳送、起重、擠壓和機床等各種機械設(shè)備控制領(lǐng)域，它可以提高工藝水平和產(chǎn)品質(zhì)量，減少設(shè)備的沖擊和噪聲，延長設(shè)備的使用壽命。采用變頻調(diào)速控制后，使機械系統(tǒng)簡化，操作和控制更加方便，有的甚至可以改變原有的工藝規(guī)范，從而提高了整個設(shè)備的功能。例如，紡織和許多行業(yè)用的定型機，機內(nèi)溫度是靠改變送入熱風(fēng)的多少來調(diào)節(jié)的。輸送熱風(fēng)通常用的是循環(huán)風(fēng)機，由于風(fēng)機速度不變，送入熱風(fēng)的多少只有用風(fēng)門來調(diào)節(jié)。如果風(fēng)門調(diào)節(jié)失靈或調(diào)節(jié)不當(dāng)就會造成定型機失控，從而影響成品質(zhì)量。循環(huán)風(fēng)機高速啟動，傳動帶與軸承之間磨損非常厲害，使傳動帶變成了一種易耗品。在采用變頻調(diào)速后，溫度調(diào)節(jié)可以通過變頻器自動調(diào)節(jié)風(fēng)機的速度來實現(xiàn)，解決了產(chǎn)品質(zhì)量問題。此外，變頻器能夠很方便地實現(xiàn)風(fēng)機在低頻低速下啟動并減少了傳動帶與軸承之間的磨損，還可以延長設(shè)備的使用壽命，同時可以節(jié)能40%。</span>云南Goodrive300-19起重**變頻器批發(fā)銷售經(jīng)過專業(yè)認證，品質(zhì)保障。</p><div

style="font-size:14px;">1、變頻器的散熱風(fēng)扇要定時清塵，發(fā)現(xiàn)其有響聲或不運轉(zhuǎn)就要更換。</span> </p> <p> <span style="font-size:14px;">2、防止雨水淋濕，通常是在刮臺風(fēng)時，窗門被風(fēng)吹壞而使變頻器淋到雨水。</span> </p> <p> <span style="font-size:14px;">3、防雷電，這個就關(guān)系到整棟樓或整個小區(qū)防雷設(shè)施問題，被雷擊的變頻器一般損壞嚴重。</span> </p> <p> <span style="font-size:14px;">4、電梯電氣室溫度不能太高，否則變頻器元件容易老化，蕞好裝有空調(diào)，效果會更好。</span> </p> <p> <span style="font-size:14px;">5、電梯電機有不正常響聲通常是變頻器有問題，如電機三相電流不平衡，這時蕞好就要維修，等到變頻器完全不行則損壞可能比較嚴重。如果自己沒有維修經(jīng)驗，一定要請專業(yè)維修人員修理。</span> 公司秉持“客戶至上”的經(jīng)營理念，希望與您攜手共創(chuàng)輝煌！</p><div
