整個(gè)控制過程如下：用氣需求↑——管路氣壓↓——壓力設(shè)定值與返饋值的差值↑——PID輸出↑——節(jié)能設(shè)備輸出頻率↑——風(fēng)機(jī)電機(jī)轉(zhuǎn)速↑——供氣流量↑——管路氣壓趨于穩(wěn)定。相應(yīng)帶來的其它好處是：供氣壓力穩(wěn)定，通過壓力調(diào)節(jié)器，可使風(fēng)機(jī)保持在設(shè)定的壓力值下工作，壓力穩(wěn)定可靠性高，而且壓力可以無級(jí)設(shè)定，隨時(shí)可調(diào)。電機(jī)實(shí)現(xiàn)軟啟動(dòng)，風(fēng)機(jī)的使用壽命及檢修周期都將得到**延長(zhǎng)。風(fēng)機(jī)排氣量由風(fēng)機(jī)的轉(zhuǎn)速來控制，氣缸內(nèi)氣閥片不再反復(fù)地開啟和關(guān)閉，閥座、彈簧等工作條件**改善，避免了高溫、高壓氣體急劇的流動(dòng)與沖擊，維修工作量減小。五、風(fēng)機(jī)電效改造方案根據(jù)風(fēng)機(jī)配置特作如下變頻改造方案：1)風(fēng)機(jī)上裝設(shè)變頻系統(tǒng)(如圖一);2)設(shè)置遠(yuǎn)程控制和就地控制兩種方式;3)保留原工頻系統(tǒng)及其聯(lián)動(dòng)方式，且和變頻器系統(tǒng)互為備用。變頻節(jié)能系統(tǒng)特點(diǎn)1、采用CHF100變頻器，調(diào)速范圍寬，變頻器調(diào)速范圍能適應(yīng)各種調(diào)速設(shè)備的要求，頻率范圍2、控制精度高，變頻器的數(shù)字設(shè)定分辨率為±±3、動(dòng)態(tài)特性好，變頻器采用自關(guān)斷器件IGBT速度快，且采用SPWM控制模式，負(fù)載電壓和頻率受控變頻器的CPU，故調(diào)節(jié)速度快，系統(tǒng)的動(dòng)態(tài)性能好;4、控制功能強(qiáng)，能滿足各種不同的控制系統(tǒng)。

電機(jī)維修是一項(xiàng)比較復(fù)雜的工作，同一個(gè)故障問題的出現(xiàn)可能原因是多方面的，這就需要我們進(jìn)行排查，并且在日常的電機(jī)修理工作中要不斷地總結(jié)經(jīng)驗(yàn)，加以歸納總結(jié)。在面對(duì)電機(jī)機(jī)體溫度過高的問題時(shí)，維修工一定要認(rèn)真分析。首先找出產(chǎn)生這一問題的原因，然后再對(duì)癥下藥。電機(jī)機(jī)體溫度過高主要有這幾種原因：一是電源的問題，比如電壓過高，遠(yuǎn)遠(yuǎn)超出了電機(jī)的額定電壓，或者電壓偏低，導(dǎo)致定子、轉(zhuǎn)子繞組溫度偏高，還有就是電壓不對(duì)稱的話也會(huì)出現(xiàn)這種狀況；二是由于電機(jī)出現(xiàn)了負(fù)載的情況。針對(duì)上述出現(xiàn)的故障原因在維修的時(shí)候就要進(jìn)行逐一排查，比如如果是電壓的問題的話就要使用跟電機(jī)額定電壓相匹配的電壓電源。而如果是電機(jī)負(fù)載的話，就要確定是由于電機(jī)功率不夠大而出現(xiàn)的負(fù)載還是由于其帶動(dòng)的機(jī)械負(fù)載工作不正常而導(dǎo)致的。如果是前者原因，就要更換功率較大的電機(jī)，如果是后者的原因就要調(diào)整拖動(dòng)機(jī)械的工作負(fù)載量。電機(jī)機(jī)體溫度過高的時(shí)候不可以盲目電機(jī)維修，修好之后還要再觀察一段時(shí)間。機(jī)床二手電機(jī)組，宜興市聚源電機(jī)維修有限公司。錫山區(qū)附近二手電機(jī)</p><p
