成功檢修好西門子直流調速裝置啟動電流大;恒稅電氣修(xiu)復此故障過十年,技術成熟,配件齊(qi),當天送機當天修(xiu)復好
?西門子(zi)直流(liu)(liu)(liu)調(diao)(diao)(diao)速(su)(su)器(qi)就是調(diao)(diao)(diao)節直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)速(su)(su)度的設備。上端(duan)和交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)連(lian)接,下端(duan)和直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)連(lian)接,直流(liu)(liu)(liu)調(diao)(diao)(diao)速(su)(su)器(qi)將交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)轉(zhuan)換成兩路輸(shu)(shu)出(chu)直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan),一路輸(shu)(shu)入(ru)給(gei)直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)機(ji)勵磁(定子(zi)),一路輸(shu)(shu)入(ru)給(gei)直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)機(ji)電(dian)(dian)(dian)(dian)(dian)樞(shu)(shu)(轉(zhuan)子(zi)),直流(liu)(liu)(liu)調(diao)(diao)(diao)速(su)(su)器(qi)通過(guo)控制電(dian)(dian)(dian)(dian)(dian)樞(shu)(shu)直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)壓來(lai)(lai)調(diao)(diao)(diao)節直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)轉(zhuan)速(su)(su)。同時直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)給(gei)調(diao)(diao)(diao)速(su)(su)器(qi)一個(ge)反饋(kui)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu),調(diao)(diao)(diao)速(su)(su)器(qi)根(gen)據反饋(kui)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)來(lai)(lai)判斷直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)機(ji)的轉(zhuan)速(su)(su)情(qing)況,必要時修正電(dian)(dian)(dian)(dian)(dian)樞(shu)(shu)電(dian)(dian)(dian)(dian)(dian)壓輸(shu)(shu)出(chu),一次(ci)來(lai)(lai)再次(ci)調(diao)(diao)(diao)節電(dian)(dian)(dian)(dian)(dian)機(ji)的轉(zhuan)速(su)(su)。
??直流(liu)調速器檢修(xiu)方法(fa)如下:
??1、檢查電樞碳刷,碳刷的(de)長度(du),接觸面和彈力都合適;
??2、檢(jian)查換向環,表面應平整,無凹痕(hen),無損傷,溝槽沒有被碳粉(fen)短路;
??3、檢查測(ce)速(su)反饋部件與(yu)電(dian)機非負載測(ce)的連(lian)軸節沒有問題。
??4、西門子直流調速器(qi)檢(jian)查馬達波箱是否(fou)有問題,漏油、潤滑不(bu)良,傳動(dong)機構磨損,可(ke)能造成負荷不(bu)平穩(wen)而使調速器(qi)頻繁調節。
??如果是模擬調速系統,對于一般的(de)電(dian)氣維(wei)修人員難(nan)度(du)會比較(jiao)大,但仍然要(yao)按以(yi)下步驟處理:
??1、測量調(diao)速器(qi)提供給(gei)電機(ji)的勵磁是(shi)否符合電機(ji)的要(yao)求并(bing)且穩(wen)定(ding)(ding),一般它應該(gai)恒定(ding)(ding),以保證磁場穩(wen)定(ding)(ding),這是(shi)恒速的有利條件;
??2、測量(liang)電(dian)(dian)樞電(dian)(dian)壓(ya)以確(que)定其變化范圍;(對于一個給定,一般可(ke)取40%左右zui大(da)給定)
??3、在上述條件(jian)下測量測速發電(dian)機的反(fan)饋電(dian)壓;
??4、在上述條(tiao)件下測量電(dian)機(ji)的電(dian)流;
??5、西門子直流調速(su)器人為增(zeng)加電機(ji)負載觀(guan)察電機(ji)轉速(su)變化(hua),如果負載增(zeng)加速(su)度明顯(xian)(xian)變化(hua),應(ying)將IMAX增(zeng)大;如果沒有明顯(xian)(xian)變化(hua),進入(ru)下一步;
??6、調(diao)整(zheng)反饋(kui)增益(增大或減小看是否(fou)有變化)如果沒有變化,恢(hui)復(fu)到調(diao)整(zheng)前位置,進入下一(yi)步(bu);
??7、調整速度環比例增益(yi),積分電(dian)容(rong),以使速度穩定;
??8、重新整定電流環參數(shu);
??9、全部設定范圍試車(che),進行(xing)精調,以求(qiu)在所有(you)速度(du)段(duan),負載(zai)任何變(bian)化下都保(bao)持速度(du)穩定;
??10、西門子直流(liu)調速器生產試車以確認滿足其(qi)工藝(yi)要求(qiu)。符(fu)合(he)要求(qiu)完成維修,不符(fu)合(he),根據需要調整參數。
成功檢修好西門子直流調速裝置啟動電流大;可(ke)解決型號(hao);西門(men)子(zi)(zi)6RA70,西門(men)子(zi)(zi)6RA80維修(xiu)(xiu),西門(men)子(zi)(zi)6RA28維修(xiu)(xiu)。
