    【全國三菱水泵專用變頻器價(jià)格】三菱水泵專用變頻器圖三菱 通用變頻器;FR-D740-2.2K-CHT訂 貨 號(hào) :FR-D740-2.2K-CHT商品型號(hào):FR-D740-2.2K-CHT

    1.變頻器的調(diào)速原理 

     交流異步電動(dòng)機(jī)的轉(zhuǎn)速計(jì)算公式為: 

     n=60f(1-s)/p 

     由公式知,改變電源的頻率時(shí),因同步轉(zhuǎn)速n與頻率f成正比變化,故異步電動(dòng)機(jī)的轉(zhuǎn)速n也隨之改變。可見變頻器調(diào)速是利用電動(dòng)機(jī)的同步轉(zhuǎn)速隨頻率變化的特性,通過改變電動(dòng)機(jī)的供電頻率進(jìn)行調(diào)速的。 

    2.變頻器的調(diào)速方法 

     變頻器是用靜止變頻裝置(晶閘管)構(gòu)成變頻電源對(duì)異步電動(dòng)機(jī)進(jìn)行調(diào)速,它采用間接變換方式(交一直一交變頻)把交流電通過整流器變成直流電,再用逆變器將直流電變?yōu)轭l率可調(diào)整的交流電供給異步電動(dòng)機(jī)。如下圖: 

     AC/f1――整流器-DC――逆變器――AC/F2 

    3.變頻器的優(yōu)點(diǎn) 

     3.1節(jié)約能源[舉例:在泵、鼓風(fēng)機(jī)和引風(fēng)機(jī)的使用中,由公式n=60f(1-s)/p知轉(zhuǎn)速與電源頻率成正比,即改變電源頻率就可以改變電動(dòng)機(jī)的轉(zhuǎn)速。理論上,流量(風(fēng)量)與轉(zhuǎn)速的一次方成正比,水壓(或風(fēng)壓)與轉(zhuǎn)速的平方成正比,所以軸功率與轉(zhuǎn)速的三次方成正比??梢?,與調(diào)節(jié)閥門相比,調(diào)節(jié)轉(zhuǎn)速具有十分明顯的節(jié)能效果。 

    3.2減少啟動(dòng)時(shí)對(duì)電網(wǎng)的沖擊(無變頻器啟動(dòng)時(shí)啟動(dòng)電流是電動(dòng)機(jī)額定電流的5~7倍)。 

    3.3減低噪聲,實(shí)現(xiàn)電動(dòng)機(jī)的軟啟動(dòng)和自由停車。 

    3.4運(yùn)行方便、準(zhǔn)確,減少了員工的勞動(dòng)強(qiáng)度。 

    3.6在泵的使用上消除了泵的喘振現(xiàn)象,使泵處于至佳運(yùn)行工況狀態(tài)。
