kw設(shè)備，晶閘管電流型交流一直流一交流變頻調(diào)速可用于幾百千瓦至2000 kw大型設(shè)備。交流一交流直接變頻調(diào)速(600r/min以下)可用于幾千千瓦以上的特大型設(shè)備(同步電動機).這種拖動系統(tǒng)的控制電路復(fù)雜，總投資較高，甚至高達電磁調(diào)速電動機的4~5倍。系統(tǒng)和大功率無換向器電動機拖動系統(tǒng)。 (1)變極對數(shù)調(diào)速拖動系統(tǒng).這種系統(tǒng)的控制電路簡單、占地面積小、維護方便、價格低廉，但系有級調(diào)速，一般*有2檔或3檔轉(zhuǎn)速。如果將此系統(tǒng)與定子調(diào)壓或電磁調(diào)速電動機結(jié)合起來，可以得到既減少轉(zhuǎn)差損耗，又在相當范圍內(nèi)平滑調(diào)速的較高效率的拖動系統(tǒng)。 (2)串級調(diào)速拖動系統(tǒng)，官方授權(quán)經(jīng)銷壓送泵規(guī)格齊全。這種系統(tǒng)適用于燒線轉(zhuǎn)子感應(yīng)電動機。優(yōu)點是變流設(shè)備容量(轉(zhuǎn)差功率)小，官方授權(quán)經(jīng)銷壓送泵規(guī)格齊全，比其他無級調(diào)速方案經(jīng)濟;缺點是必須使用繞線轉(zhuǎn)子感應(yīng)電動機，功率因數(shù)低，官方授權(quán)經(jīng)銷壓送泵規(guī)格齊全，增加電機損耗，**商轉(zhuǎn)速降低?，F(xiàn)已開發(fā)出多種改善功率因數(shù)的線路.雙饋電機可克服一般申級調(diào)速的一些缺點</p><div

2、雙速特性減少了打壓次數(shù)，在低壓室快速處于負載用功狀態(tài)，立刻轉(zhuǎn)換成高壓，縮短每次作業(yè)周期。 </p> <p> 3、配有壓力調(diào)節(jié)閥，可調(diào)節(jié)控制及設(shè)定工作壓力 </p> <p> <br /> </p> <p> 單液壓送泵是為液壓傳動提供加壓液體的一種液壓元件，是泵的一種。它的功能是把動力機（如電動機和內(nèi)燃機等）的機械能轉(zhuǎn)換成液體的壓力能。影響液壓泵的使用壽命因素很多，除了泵自身設(shè)計、制造因素外和一些與泵使用相關(guān)元（如聯(lián)軸器、濾油器等）的選用、試車運行過程中的操作等也有關(guān)。 </p> <p> 液壓泵的工作原理是運動帶來泵腔容積的變化，從而壓縮流體使流體具有壓力能。 </p> <p> 務(wù)必具備的條件就是泵腔有密封容積變化。 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
