熱電偶是應(yīng)用**普遍的測(cè)溫傳感器，而熱電偶保護(hù)管材料的性能影響熱電偶長(zhǎng)期穩(wěn)定性、使用壽命等各項(xiàng)性能指標(biāo)，氮化硅陶瓷保護(hù)管與熱電偶配套使用，起到保護(hù)熱電偶，使熱電偶在特殊環(huán)境下能正常工作，且能防腐耐高壓高流速等。一、熱電偶保護(hù)管制作工藝的選擇：熱電偶熱電阻套管制作有兩種工藝：一為鋼管焊接式，一為整體鉆孔式。鋼管焊接式為鋼管一端封堵成形，套管一般壁較薄，內(nèi)孔較大，因此抗壓能力不高，多只能到。如果套管安裝在管道上，即使操作壓力很小，但由于流體流速較大，套管也會(huì)在沖擊力的振動(dòng)下發(fā)生斷裂損壞，比如循環(huán)水泵出口位置的套管，如果選擇不當(dāng)，極易發(fā)生損壞，甚至。同時(shí)，因鋼管內(nèi)孔均較大，因此套管內(nèi)部存在更多的導(dǎo)熱間隔，造成測(cè)量反應(yīng)速度慢。整體鉆孔式為實(shí)心棒料鉆孔成形，套管內(nèi)孔小，與測(cè)量元件緊密配合，因此，反應(yīng)速度快，抗振效果好。且抗壓能力高，可達(dá)到30MPa以上。根據(jù)上述兩種工藝的優(yōu)缺點(diǎn)，對(duì)于套管工藝，推薦選用整體鉆孔套管。目前，國(guó)內(nèi)先進(jìn)的鉆孔技術(shù)采用單端深盲孔整體鉆孔工藝，套管內(nèi)孔直徑*為Φ，與國(guó)際標(biāo)準(zhǔn)的Φ6mm測(cè)量元件實(shí)現(xiàn)完好的配合。二、熱電偶保護(hù)管形式的選擇：在相同長(zhǎng)度下。
