故障現(xiàn)象：我院日產(chǎn)8430K遙測心電監(jiān)護(hù)儀記錄器工作不正常。開機(jī)后，顯示正常，按下記錄開關(guān)，走紙正常，但記錄紙上的信號時(shí)有時(shí)無。故障檢修：很顯然儀器的記錄部分有接觸不良。該機(jī)的記錄部分包括記錄控制，記錄驅(qū)動和記錄器三部分。在故障時(shí)，通過手動自檢未發(fā)現(xiàn)vp-0511記錄板有故障。在通電記錄時(shí)用手板動VP0659記錄驅(qū)動板，對故障的有無未產(chǎn)生改變，所以故障不在VP0659上，檢查了這兩塊板到記錄器上的連接無損后，將注意力集中到RG712記錄器上。該記錄器上包括直流電機(jī)，傳感器和熱筆頭三部分。由于記錄時(shí)走紙順暢且走紙感應(yīng)燈工作正常，所以故障很有可能出在熱筆頭部分。該部分集中在一塊小電路板上，上有十二片大規(guī)模集成塊(MSl)。由VP-0659記錄驅(qū)動板傳送過來的串行數(shù)據(jù)信號(SIN)，時(shí)鐘信號(CLK)，選通信號(STB)，分別通過這十二片MSI塊驅(qū)動熱敏元件各工作。經(jīng)仔細(xì)檢查發(fā)現(xiàn)電路板上串行數(shù)據(jù)輸人信號(SIN)到MSI片的連接上有輕微裂痕，經(jīng)處理焊接后，故障排除，為醫(yī)院節(jié)約了維修費(fèi)用。調(diào)查故障原因是使用者頻繁地開關(guān)記錄走紙倉且用力不適，造成記錄器上的小電路板振動過大而引起端裂。柳州AESCULAP蛇牌PV440攝像機(jī)屏蔽線更換或修復(fù)不循環(huán)方式貯存，另企業(yè)十萬級潔凈區(qū)清洗間內(nèi)注射用水和潔具間內(nèi)純化水管路存在死水段，。</p><div
