D57Mo堆焊金屬硬度較高，用于閘板；D577堆焊金屬硬度較低，用于堆焊閥體或閥座密封面。兩者組成的密封面可獲得良好的抗擦傷性能。堆焊層的高度加工后應(yīng)在5mm以上，以保證硬度和成份穩(wěn)定。堆焊要按焊接工藝規(guī)定操作，焊接電流不可過大以防止焊條成份發(fā)生變化影響焊接質(zhì)量。3硬質(zhì)合金硬質(zhì)合金中常用的是鈷基硬質(zhì)合金也稱鈷鉻鎢硬質(zhì)合金。它的特點(diǎn)是耐腐蝕、耐磨、抗擦傷，特別是紅硬性好，即在高溫下也能保持足夠的硬度，此外加工工藝性適中，其許用比壓8～1MPa，國外資料介紹155MPa。
b大修后必須進(jìn)行伏安特性試驗，冷態(tài)試驗和熱態(tài)試驗可以根據(jù)需要結(jié)合分部試運(yùn)轉(zhuǎn)及整體試運(yùn)行時進(jìn)行，以對設(shè)備進(jìn)行評級和評價檢修工作.電除塵器維修機(jī)械部分電場內(nèi)部及灰斗積灰清除。用人工敲打等方法將電場內(nèi)陰極框架極線、陽極板排及灰斗的積灰清除干凈。陰、陽極間距檢查調(diào)整：檢查陽極板和陰極框架，對變形部分進(jìn)行校正，保證極距偏差為1mm，使極距符合設(shè)計要求。振打裝置檢修。檢查陰振打器連接及安裝位置有無跑偏，振打錘是否與振打桿對中，逐個振打器進(jìn)行調(diào)整校正，振打棒露出長度符合設(shè)計要求（382MM）；檢查陽極振打是否正常，對存在問題進(jìn)行處理。
量程變化范圍從理論上講為無限大，加之儀表輸出信號與容積流量呈線性關(guān)系，其量程變換容易，故電磁流量計可制作成多量程及量程自動切換式儀表。智能電磁流量計的測量準(zhǔn)確度和穩(wěn)定性隨著測量線路的合理化和集成化在不斷提高，特別是微處理機(jī)的應(yīng)用，使智能電磁流量計的準(zhǔn)確度和抗干擾能力明顯提高。因為智能電磁流量計對流體縱向速度分量敏感，對環(huán)流不敏感，所以流量計前后的直管段要求比其他流量計短。智能電磁流量計反應(yīng)靈敏，能測定正、反方向的流體流量，可用以測脈動流量，其輸出信號適于作為自動調(diào)節(jié)系統(tǒng)的流量信號。
不同的儀表有不同的k，并隨儀表長期使用的磨損情況而變化。盡管渦量計的設(shè)計尺寸相同，但實(shí)際加工出來的渦輪幾何參數(shù)卻不會完全一樣，因而每臺渦輪變送器的儀表常數(shù)k也不完全一樣，它通常是制造廠在常溫下用潔凈的水標(biāo)定出來的。渦輪變送器輸出的脈沖信號，經(jīng)前置放大器放大后，送入顯示儀表，就可以實(shí)現(xiàn)流量的測量[5]。渦輪流量計特點(diǎn)具有精度高、重復(fù)性好、無零點(diǎn)漂移、高量程比等優(yōu)點(diǎn)。渦輪流量計擁有高質(zhì)量軸承、特別設(shè)計的導(dǎo)流片，因此極大降低了磨損，對峰值不敏感，甚者惡劣的條件下也可以給出可靠的測量變量。
