1、檢查(cha)電(dian)樞碳刷,碳刷的長度,接觸面和彈力都合適;
2、檢查(cha)換向環,表面(mian)應平(ping)整,無凹痕,無損傷,溝槽沒有(you)被碳粉短路;
3、檢查測(ce)速反饋部件與電機非負載測(ce)的連軸(zhou)節沒有(you)問題(ti)。
4、檢查馬達波箱是否有問題(ti),漏油、潤滑(hua)不良,傳動機構(gou)磨損,可能造成負荷不平穩而使調(diao)速器頻繁調(diao)節。
如果是模擬調速系統,對于一般的電氣維修(xiu)人員(yuan)難度會(hui)比(bi)較大,但仍然要按(an)以下步(bu)驟處理:
1、測量調速器提供(gong)給電機的(de)勵(li)磁是(shi)否符合電機的(de)要(yao)求(qiu)并且(qie)穩定(ding)(ding),一般它應該(gai)恒定(ding)(ding),以(yi)保證磁場穩定(ding)(ding),這(zhe)是(shi)恒速的(de)有利條件;
2、測量電樞電壓以確定(ding)其變化范圍(wei);(對于一個(ge)給定(ding),一般可(ke)取40%左右zui大給定(ding))
3、在上述(shu)條件(jian)下測量測速(su)發電機的反饋電壓;
4、在上述條(tiao)件下測量電機的電流;
5、人為增(zeng)(zeng)加(jia)電機負(fu)載觀察電機轉(zhuan)速變(bian)(bian)化(hua),如果(guo)負(fu)載增(zeng)(zeng)加(jia)速度明(ming)(ming)顯變(bian)(bian)化(hua),應將IMAX增(zeng)(zeng)大;如果(guo)沒(mei)有明(ming)(ming)顯變(bian)(bian)化(hua),進入(ru)下一步;
6、調(diao)整反饋增益(增大或減小看是否有變(bian)化)如果(guo)沒(mei)有變(bian)化,恢復到(dao)調(diao)整前(qian)位置(zhi),進入下(xia)一步;
7、調整速(su)度環(huan)比例增益,積分電容,以(yi)使速(su)度穩定(ding);
8、重新整定(ding)電流環參(can)數;
9、在(zai)全部設(she)定范圍試(shi)車,進行精調,以求在(zai)所有速度(du)段,負載任何變化下都保(bao)持速度(du)穩(wen)定;
10、生產試車以確認滿足其工藝要求。符(fu)(fu)合要求完成(cheng)維修,不符(fu)(fu)合,根據需要調(diao)整參數。
