2. Zaɓin kayan aikin daban-daban don magoya bayan centrifugal masu zafi mai zafi (dukkanin injin daidaitawa)
Blade: Mafi girman zafin jiki, mafi mahimmanci don zaɓar karfe / bakin karfe, da yin ma'auni mai ƙarfi + magani mai zafi.
Casing: Daidai da ma'aunin zafin jiki, na iya zama ɗan ƙasa kaɗan
Shaft: Don sassan zafin jiki, 40Cr, 42CrMo, 15CrMo yakamata a ba da fifiko
Akwatin ɗaukar hoto: Sassan zafin jiki na yau da kullun, Q235 ya isa, dole ne a sanye da magoya baya masu zafi da jaket mai sanyaya ruwa.
Abubuwan rufewa:
≤250℃: asbestos shiryawa, fluororubber
> 250 ℃: karfe labyrinth hatimi, carbon zobe hatimin
3. Ƙarin zaɓi don yanayin lalata na magoya bayan centrifugal masu zafi
Acid da alkali-dauke da hayaki gas: 316L> 304> carbon karfe
Ya ƙunshi ions chloride: haramtacce 304, dole ne ya zama 316L/2205 duplex karfe
Babban ƙura mai ƙura: ƙara rufin da ba ya jurewa, yumbu mai jure lalacewa
4. Mahimman abubuwan da za a yi la'akari da su don zaɓin fan na centrifugal mai zafi
Zazzabi> 200 ℃: dole ne a yi amfani da akwati mai sanyaya ruwa
Zazzabi> 300 ℃: ƙara zafi rufi shaft hannun riga, fadada hadin gwiwa
Bakin karfe ruwa: dole ne a sha magani mai ƙarfi don hana nakasawa da fashewa
