產(chǎn)品詳情
按比例地改V和f時,電機(jī)的轉(zhuǎn)矩如何變化?頻率下降時完全成比例地降低電壓,那么由于交流阻抗變小而直流電阻不變,將造成在低速下產(chǎn)生地轉(zhuǎn)矩有減小的傾向。在低頻時給定V/f,要使輸出電壓提高一些,以便獲得一定地起動轉(zhuǎn)矩,這種補(bǔ)償稱增強(qiáng)起動??梢圆捎酶鞣N方法實(shí)現(xiàn),有自動進(jìn)行的方法、選擇V/f模式或調(diào)整電位器等方法。在說明書上寫著變速范圍6~6Hz,即1:1,那么在6Hz以下就沒有輸出功率嗎?在6Hz以下仍可輸出功率,但根據(jù)電機(jī)溫升和起動轉(zhuǎn)矩的大小等條件,低使用頻率取6Hz左右,此時電動機(jī)可輸出額定轉(zhuǎn)矩而不會引起嚴(yán)重的發(fā)熱問題。

明桿閘閥:由于能較直觀顯示其啟閉程度,所以多年來中小通徑被廣泛應(yīng)用,通常DN小于等于8mm選用明桿閘閥。暗桿閘閥:其閥桿螺母在閥體內(nèi)與介質(zhì)直接接觸。適用于大口徑閥門和安裝空間受限制的管路,如地下管線。蝶閥其名稱來源于翼狀結(jié)構(gòu)的蝶板。在管道上它主要用于切斷和節(jié)流,當(dāng)?shù)y用于切斷時,多用彈性密封,材料選橡膠、塑料等,當(dāng)用于節(jié)流時,多用金屬硬密封。鴻豐蝶閥的優(yōu)點(diǎn)是體積小,重量輕,結(jié)構(gòu)簡單,啟閉迅速,調(diào)節(jié)和密封性能良好,流體阻力和操作力矩較小。

對于光學(xué)玻璃加工過程中不可避免的表面燒蝕問題,其成因是由于光學(xué)玻璃的主要成分金屬氧化物水解反應(yīng)導(dǎo)致的,通??刹捎眠^堿性清洗的方法,并通過外力(超聲波)的作用消除燒蝕印痕LCD清洗屬于精密清洗領(lǐng)域,對清洗的質(zhì)量、效率要求很高,以前,LCD工廠大多使用的是ODS清潔劑和超聲氣相清洗技術(shù),在上加速淘汰ODS清潔劑的壓力下,LCD廠正在積極選用替代ODS清潔劑(或稱非ODS清洗劑),替代清洗劑必須保證清洗的LCD質(zhì)量不低于原用ODS清洗劑的清洗標(biāo)準(zhǔn),甚至更高。
