產(chǎn)品詳情
EDS分析結(jié)果表明這種分布在晶界上的碳化物鉻含量明顯高于基體。這種碳化物是M23C6型。隨碳化物的析出,又得不到鉻的擴(kuò)散補(bǔ)充時(shí),以碳化鉻的形式沿奧氏體晶界析出,在碳化物周?chē)纬韶氥t區(qū),從而奧氏體不銹鋼晶界易被腐蝕。所以沿晶界析出的碳化物是造成蝶閥銹蝕的主要原因。經(jīng)固溶處理后的奧氏體不銹鋼,由于在高溫加熱時(shí)大部分碳化物被溶解,奧氏體中飽和了大量的碳與鉻,并因隨后的快速冷卻而固定下來(lái),使材料有很商的耐腐蝕性。

一般而言,特定的泵管尺寸、泵管材料、泵頭類型、以及運(yùn)轉(zhuǎn)速度這幾項(xiàng)參數(shù)的組合決定了泵管的使用壽命。泵管使用壽命,或在泵中的撓曲屈服極限是投入新應(yīng)用前的首要考慮因素。如今,在系統(tǒng)中使用熱塑性合成橡膠(TPE),泵管運(yùn)行壽命超過(guò)5小時(shí)已是很尋常的事情。在某一特定應(yīng)用場(chǎng)合中,泵的性能是非常穩(wěn)定的。挑選抗撓曲能較大的管材、采用較厚的管壁、及/或挑選較大的泵及使用較低的運(yùn)轉(zhuǎn)速度等均可大限度地延長(zhǎng)泵管的使用使命。

一般水源低于或等于泵的擺放位置時(shí),就需要泵有自吸能力。儀器儀表行業(yè)經(jīng)常使用微型水泵進(jìn)行流體轉(zhuǎn)移,具有良好自吸能力的微型真空水泵大有用武之地。微型真空水泵在吸入行程時(shí),泵腔內(nèi)會(huì)產(chǎn)生一定的真空度,當(dāng)?shù)卮髿鈮号c泵腔內(nèi)壓力之差(即相對(duì)真空度)推動(dòng)流體進(jìn)入泵腔,在泵的排出行程時(shí)壓出流體。相對(duì)真空度換算成水柱既是吸程。國(guó)內(nèi)先進(jìn)的氣海調(diào)速微型真空水泵由于結(jié)構(gòu)設(shè)計(jì)合理,體積相當(dāng)小,吸程卻可以達(dá)到3m。微型真空水泵不同于離心泵,一般在計(jì)算吸程時(shí)不用計(jì)算汽蝕余量。
