通過D2、D4為主機提供工作電源。在主機關(guān)機狀態(tài)時，電源電路根據(jù)蓄電池的電壓高低進行全自動充電控制。電路主要由LM301、R4、R10、N2等元件組成。當(dāng)蓄電池電壓低于規(guī)定值時，R9有電流流過產(chǎn)生壓降(蓄電池電壓越低，R9產(chǎn)生的壓降越大)，則LM301同相輸入端電壓低于反相輸入端電壓，其輸出端V6為低電位，此時狀態(tài)與主機開機工作一樣N1飽和導(dǎo)通，風(fēng)扇啟動，為LM338散熱，N2截止，LM338輸出電壓為V0=，給蓄電池充電。蓄電池在充電的過程中，電池電壓逐漸升高，流過R9的電流也越來越小，在R9兩端產(chǎn)生的壓降也不斷減少，即LM301的3腳電壓會逐漸升高。當(dāng)LM301的3腳電壓達(dá)到或稍高于2腳電壓時，輸出端V6為高電位，則N1截止，電機停止轉(zhuǎn)動，N2飽和導(dǎo)通，將R4對地幾乎短路，Re約等于R10的值(Re=1KW)，則LM338輸出電壓為V0=，從而蓄電池處于微電流充放電狀態(tài)。另外R3和C1在電路中起著慢放電和延長電池壽命的作用。故障分析a.一般故障現(xiàn)象此類電源常見故障及其處理方法一般有：(1)變壓器T1無電壓輸出，通常是保險絲FUSE1、FUSE2熔斷或變壓器損壞。(2)LM338無電壓輸出，應(yīng)檢查反饋電阻R1、R4、R10、R14及LM301。如反饋回路正常，則LM338損壞。(3)開機風(fēng)扇不轉(zhuǎn)，則重點檢查N1、M1和LM301。</p><p> 故障分析首先判斷是正壓還是負(fù)壓，接著檢查原始壓力是否達(dá)到要求，然后進入狀態(tài)顯示欄(按Select-7.保養(yǎng)-5.狀態(tài)顯示欄)，按START開始鍵，觀察具體在哪一步時壓力超出儀器監(jiān)測范圍的，再根據(jù)水路圖分析壓力的分配情況，判斷故障所在。故障處理在儀器報警后，按HELP鍵發(fā)現(xiàn)是250mmHg壓力錯誤，但此時的壓力卻又在儀器監(jiān)測范圍(230mmHg-270mmHg())內(nèi)，打開儀器外殼，拆開壓力調(diào)整單元確定正負(fù)壓的原始壓力，但把負(fù)壓三通用手指壓住后，發(fā)現(xiàn)達(dá)到600mmHg()左右的壓力所需時間明顯延長(正常應(yīng)在10s左右)，即壓力上升的比較緩慢。細(xì)查發(fā)現(xiàn)是因三通和其聯(lián)結(jié)的管路很臟造成。拆下清洗后重新接上，故障排除。4故障現(xiàn)象四儀器白細(xì)胞不分類現(xiàn)象能達(dá)到70％以上。故障分析首先檢查試劑，如果沒問題，則觀察WBC直方圖分布是否正常，一般用質(zhì)控血來判斷，根據(jù)質(zhì)控狀況來調(diào)整WBC靈敏度；如果故障依舊，則可能是電路板PCB；然后檢查WBC檢測部；后面檢查模擬板。故障處理修理中發(fā)現(xiàn)該儀器近期未按要求使用原裝試劑，為節(jié)約成本而使用了國產(chǎn)的試劑(同時更換了溶血素和稀釋液)。因為儀器的設(shè)計是基于試劑處理細(xì)胞后的形態(tài)來分析的，所以當(dāng)試劑的滲透壓、電導(dǎo)率等發(fā)生變化時。將原HDD0硬盤換回，再替換HDD2，此時設(shè)備可正常啟動，由此確定HDD2損壞導(dǎo)致故障。</p><div

從而發(fā)生聲波的反射與折射等現(xiàn)象。就比如一個人朝著山間空谷大喊大叫時，所聽到的山谷回音；以及早期的雷達(dá)掃描在朝某一定點方向發(fā)射聲波，遇到飛機或其他物體即產(chǎn)生原方向上的反射波，被雷達(dá)站接收后即可判斷有無物體接近及其距離等信息。這些都是利用波的反射原理。同樣，人體是一個復(fù)雜的有機整體，人體內(nèi)分布有許許多多各不相同的組織和部位結(jié)構(gòu)，它們對超聲波存在著不同的聲阻抗，從而當(dāng)超聲波通過人體某些部位和部位時，在不同組織小小的相鄰界面上產(chǎn)生各不相同的反射、折射、散射與衍射等，這些信息被特殊的儀器接收后通過電子計算機等電子工程技術(shù)處理后以一定的特殊形式顯示出來，醫(yī)務(wù)人員通過對比可疑病患者與正常人體相同部位或部位的以上各種超聲波信息之后，判斷該可疑病患者其檢查部位或部位是否存在異常病變并做出診斷。目前，由于超聲顯像技術(shù)具有實時動態(tài)、靈敏度高、易操作、無創(chuàng)傷、無特殊禁忌癥、可重復(fù)性強、費用低廉和無放射性損傷等優(yōu)點。從而使這一診斷技術(shù)成為了現(xiàn)今臨床各學(xué)科疾病的檢查、診斷和介入治理中所不可缺的重要手段之一。其特點為：1、超聲檢查是無損傷、無痛苦、無電離輻射的影像技術(shù)，一般無需使用造影劑或靜脈注射藥。相關(guān)人員要控制彩超室溫度，不要使室溫過高而影響設(shè)備的正常運轉(zhuǎn)。成都AESCULAPPV440攝像機故障與維修</p><p
