離合器分離不徹底,即通常所說的踩下離合器時換檔時發(fā)出聲響。這一故障常有如下兩種現(xiàn)象:汽車起步時,將離合器踏到底仍感到換檔困難,雖強行將變速桿置入檔位,但在不放松踏板時,汽車向前移動或發(fā)動機熄火;變速時換檔困難或變速桿無法置入檔位,并且變速器發(fā)出齒輪撞擊聲。
離合器分離不徹底的主要原因在于摩擦力矩沒有完全消除。起動發(fā)動機,將離合器踏板踩到底,松開手制動,換各檔試驗,若換檔困難或變速桿無法置入檔位,且變速器有明顯的齒輪撞擊聲;再稍用力將變速桿推入檔位,不抬離合器踏板,察看后輪是否轉(zhuǎn)動,若后輪轉(zhuǎn)動或發(fā)動機熄火,可判斷為離合器分離不徹底。
在發(fā)動機熄火的狀態(tài)下,將變速桿置于空檔,一人將離合器踏板踩到底,一人搖轉(zhuǎn)發(fā)動機,另一人打開離合器底蓋,觀察從動盤是否同主動部分一起轉(zhuǎn)動,若一起轉(zhuǎn)動,可判定為離合器分離不徹底。
變頻整流器在調(diào)試過程中要注意以下幾點:仔細確認實驗前的檢查項目,避免上電時出現(xiàn)短路、接地等故障,確認好各互感器的極性,校準互感器。確認各整流元件上的脈沖正確,主回路先接低壓電源,然后對整流器的電壓、電流控制參數(shù)進行預調(diào)試,額定電壓調(diào)試時要特別注意防止觸電。調(diào)試結(jié)果表明,雙PWM變頻系統(tǒng)工作可靠,其中整流器所采用的三電平PWM矢量變換控制思想,技術(shù)先進,系統(tǒng)運行穩(wěn)定,實現(xiàn)了cos5=1.0的整流器運行目標。
自動化程度高,現(xiàn)場檢測信號數(shù)量多且分散,生產(chǎn)中經(jīng)常出現(xiàn)堆鋼、不規(guī)律的自由停車等,很難確定故障原因。數(shù)據(jù)采集分析(PDA)系統(tǒng)連續(xù)監(jiān)視記錄全線自動化系統(tǒng)的運行信息,并且可以離線對記錄信號進行分析,找出引起故障的起始信號,很大程度上解決了上述問題
PDA系統(tǒng)是德國西門子公司隨軋線自動化控制系統(tǒng)成套提供的。由于原系統(tǒng)初設定的信號采集較少,生產(chǎn)后出現(xiàn)的有些問題僅憑已有信號不能分析清楚,于是安鋼高線廠對原有系統(tǒng)的信號采集進行了重新配置和改造。工業(yè)控制軟件實現(xiàn)上下位機之間的連接和數(shù)據(jù)交換,將PLC的內(nèi)存儲器作為變量,按照字節(jié),字,雙字等形式進行傳輸和處理,上下位機的硬件連接通過SIEMENS提供的PC/PPI電纜來實現(xiàn)。
