微型直流電機實質(zhì)上就是一個直流電動馬達，通電后轉(zhuǎn)速通常很高，至少幾百轉(zhuǎn)/分，更高點的可以達到上萬轉(zhuǎn)，在這種情況下，電機的力矩很小，無法帶動較重的東西，但是由于直流電機具有低轉(zhuǎn)速、大力矩的特點，這點事交流電機無法取代的，這樣我們就可以通過減速器調(diào)節(jié)直流電機的轉(zhuǎn)速，也可以通過電子調(diào)速器達到無級減速的目的。
微型直流減速電機：具有高精度、低噪音、長壽命、承載能力強等特點，完全可替代同型號的高品質(zhì)的進品產(chǎn)品.由于具備減速范圍寬廣，力能指標高，使用方便，運行可靠等特點，而被廣泛應(yīng)用于各類小型輕工機械、包裝、食品、紡織、化妝(美容)機械、印刷設(shè)備、儀器及各種自動化設(shè)備、生產(chǎn)線上。采用高精度齒輪，并配油封，O型環(huán)密封式齒輪箱，采用潤滑脂浴潤方式，具有噪音低，使用壽命長、體積小、功率大等特點。減速范圍寬廣，減速比1：31:1500還可根據(jù)用戶對轉(zhuǎn)速的特殊要求，另行制作。配用的微型電動機分為：微型交流電機(單相：220v、110v;三相：220v、380v)。

五、電動機運行時響聲不正常有異響
故障原因①軸承磨損或油內(nèi)有砂粒等異物；②轉(zhuǎn)子鐵芯松動；③軸承缺油；④電源電壓過高或不平衡。
故障排除①更換軸承或清洗軸承；②檢修轉(zhuǎn)子鐵芯；③加油；④檢查并調(diào)整電源電壓。
六、運行中電動機振動較大
故障原因①由于磨損軸承間隙過大；②氣隙不均勻；③轉(zhuǎn)子不平衡；④轉(zhuǎn)軸彎曲；⑤聯(lián)軸器（皮帶輪）同軸度過低。
故障排除①檢修軸承，必要時更換；②調(diào)整氣隙，使之均勻；③校正轉(zhuǎn)子動平衡；④校直轉(zhuǎn)軸；⑤重新校正，使之符合規(guī)定。

精明之選窗臺石材選購需知如果認定了家里的窗臺裝修要選擇某種石材，也知道了通過測量窗臺面積確定石材的面積，那么就為選購到合適的石材做好了基本的準備。下面我們就來看看，選購窗臺石材，還需要注意哪些問題。選定購買方式窗臺石材的購買方式有兩種，一種是選擇讓商家上門服務(wù)，一種是自己去石材市場挑選加工，然后運回來自己或請人安裝，兩種方式各有利弊。問價問清楚選購窗臺石材時一定要把以下幾項談清楚：板材的價格;磨邊的費用;安裝的費用;是否加損耗，加多少;掏孔、打磨、粘接的費用;切口費;防護的費用;運輸?shù)馁M用;上門測量是否要交定金。

IKO軸承溫度升高的原因：軸承冷卻水中斷。油質(zhì)劣化，油自身不清潔或運行中油劣化，如油中的水分增加會引起油的酸性增大，會降低油的潤滑作用，使軸瓦遭到腐蝕，造成軸承溫度升高?，F(xiàn)象：有警報電鈴響.機旁盤水輪機械故障光字牌亮，指示IKO軸承溫度的儀表溫度升高，信號繼電器動作。溫度計盤（膨脹型溫度計）黑針與黃針重合或超過黃針。發(fā)出軸承溫度升高的故障信號。處理當(dāng)IKO軸承溫度升高時，首先判斷是否誤動作，如確實升高，應(yīng)做如下處理：檢查冷卻水水壓，水流及管路系統(tǒng)是否正常。
