就到了X線電離室限位開關(guān)S15，經(jīng)S15的常閉觸點(diǎn)送至K3線圈，K3得電，電離室架運(yùn)動，當(dāng)X線電離室移至小機(jī)頭中心寸，S15動作，K3失電，電機(jī)停轉(zhuǎn)。測STB7-26為-12V，正常為24V，H1J1-20也為-12V。經(jīng)過S15再向前查，測H1J1-12，也為-12V，而H1J1-13為24V。說明故障在小機(jī)頭內(nèi)，很可能S5-S10有問題。在拆機(jī)頭前，先將機(jī)架旋轉(zhuǎn)1800。，使機(jī)頭在下方，然后將機(jī)架的定位鞘插好(切記)。關(guān)掉機(jī)器，安裝好吊裝設(shè)備，將配件架、小機(jī)頭蓋、鎢門部分一一吊走，再將電離室和靶-箔部分吊起，檢查其下方S5-S10限位開關(guān)。壓合S8時(shí)，沒響聲。S8壓合后，沒彈起，銀川奧林巴斯UES40高頻電刀主機(jī)維修，常閉觸點(diǎn)斷開。將S8修復(fù)，開機(jī)設(shè)置X線，電離室運(yùn)動正常。再將小機(jī)頭各部分一一裝好，恢復(fù)工作。由于S8常閉觸點(diǎn)斷開，24V在此截止，在S10與S15之間供X-RTARGETIND的-24V就可通過一電阻送到H1J1-12和H1J1-20。所以在此所測電壓變?yōu)?12V。2故障二故障現(xiàn)象經(jīng)常出現(xiàn)電子線各檔之間轉(zhuǎn)換困難的現(xiàn)象，有時(shí)要預(yù)置好幾遍FOIL才滅。后面FOIL干脆不滅。試驗(yàn)各檔電子及X線，機(jī)頭內(nèi)無任何響聲?？赡馨?箔轉(zhuǎn)換部分有故障。預(yù)置好一檔電子線后，測STB7-21，為+24V，H1J1-18也為+24V。說明靶-箔電機(jī)得電，銀川奧林巴斯UES40高頻電刀主機(jī)維修，銀川奧林巴斯UES40高頻電刀主機(jī)維修，很可能靶-箔架被卡住，故障在小機(jī)頭內(nèi)。我們看看在夏季的氣候特點(diǎn)下，如何更好地保證超聲設(shè)備良好運(yùn)行。銀川奧林巴斯UES40高頻電刀主機(jī)維修</p><div

故障：現(xiàn)象屏幕無顯示，且風(fēng)扇也不轉(zhuǎn)分析與處理：該機(jī)維修年后出現(xiàn)同樣故障現(xiàn)象。在現(xiàn)場，發(fā)現(xiàn)臺交流穩(wěn)壓電源串聯(lián)后，再給供電。去掉臺交流穩(wěn)壓電源，直接將輸入，仍然沒有顯示，查外部保險(xiǎn)絲正常?？梢源_定儀器已經(jīng)損壞。于是打開機(jī)器，取出電源盒，重點(diǎn)檢查等，都沒有明顯損壞，各級輸出無短路現(xiàn)象，其他元件也沒有明顯損壞，切的集電極已經(jīng)有電壓。考慮到的故障率比較高，于是買一個(gè)，更換后電源工作正常。討論一下為什么第二次損壞？我認(rèn)為是由于串聯(lián)的個(gè)交流穩(wěn)壓電源引起的。這個(gè)交流穩(wěn)壓電源都屬于參數(shù)調(diào)整型交流穩(wěn)壓電源，即由一個(gè)飽和電抗和一個(gè)電容并聯(lián)而成。交流穩(wěn)壓電源的等效阻抗隨時(shí)在變化，當(dāng)還沒有進(jìn)入飽和時(shí)，等效阻抗呈容性；當(dāng)進(jìn)入飽和時(shí)，等效阻抗呈感性。故首先個(gè)交流穩(wěn)壓電源輸出受第二個(gè)交流穩(wěn)壓電源等效阻抗的影響，輸出波形有較多的諧波（作為第二個(gè)交流穩(wěn)壓電源的輸入）。而參數(shù)調(diào)整型交流穩(wěn)壓電源對電源的頻率非常敏感，所以第二個(gè)交流穩(wěn)壓電源的輸出電壓的輸入）隨工作頻率的變化而變化。在第二個(gè)交流穩(wěn)壓電源的輸出電壓瞬間偏高時(shí)被損壞?？偨Y(jié)2次維修，開關(guān)電源不起振一般有種情況。一是電源部件故障，二是負(fù)載短路引起電源自動保護(hù)。銀川奧林巴斯UES40高頻電刀主機(jī)維修如果發(fā)現(xiàn)軌跡球打開清潔之后，操作仍然不靈敏，請及時(shí)聯(lián)系維修商。</p><div

垂直于聲束軸線的方向上能夠區(qū)分兩上回波目標(biāo)的小距離。該值越小，聲像圖橫向界面的層理越清晰。其影響因素包括：1．聲束寬度聲束越窄，側(cè)向分辨力越好。而聲束寬度與晶片直徑和工作頻率有關(guān)。但是換能器尺寸不可能做得很大，頻率不能無限高。因此設(shè)計(jì)者采取了透鏡、可變孔徑技術(shù)，在設(shè)計(jì)中應(yīng)用了分段動態(tài)聚焦和連續(xù)動態(tài)聚焦，從而提高了側(cè)向分辨力。2.系統(tǒng)動態(tài)范圍在換能器產(chǎn)生的有方向性聲場內(nèi)，聲壓（或聲強(qiáng)）并不是均勻分布的。一般有這樣的規(guī)律，隨著增益的升降聲束寬度相應(yīng)地變寬和變窄，而目標(biāo)回波聲像的橫向尺寸也相應(yīng)地拉長和縮短。3.顯示器亮度和媒質(zhì)衰減系數(shù)顯示器亮度和媒質(zhì)衰減系數(shù)等都會影響側(cè)向分辨力，所以在測量側(cè)向分辨力時(shí)，一定要將設(shè)備的增益和亮度調(diào)到佳狀況。（五）幾何位置示值誤差指B超設(shè)備顯示的和測量的實(shí)際目標(biāo)尺寸和距離的準(zhǔn)確度。在實(shí)際應(yīng)用中主要測量縱向幾何位置示值誤差和橫向幾何位置示值誤差。這個(gè)技術(shù)參數(shù)對測量生物體內(nèi)病灶尺寸是很有影響的，涉及到診斷與治理的一致性。影響這一準(zhǔn)確度的因素,與聲速設(shè)定和掃描規(guī)律形式有關(guān)的扇形圖像的均勻性，它比平面線陣掃描幾何位置準(zhǔn)確度差些。。甚至完全失效，進(jìn)而可能造成圖像干擾、易發(fā)故障甚至出現(xiàn)安全問題。銀川奧林巴斯UES40高頻電刀主機(jī)維修</p><p
