Ni afikun si omi, Pupọ julọ awọn media ti a lo ninu oluyipada ooru awo jẹ ojutu ti o tẹẹrẹ, ojutu ọlọrọ, sodium hydroxide, sulfuric acid ati awọn media kemikali miiran, eyiti o rọrun lati fa ibajẹ ti awo ati wiwu ati ti ogbo ti gasiketi.
Awo ati gasiketi jẹ awọn eroja akọkọ ti oluyipada ooru awo, Nitorina yiyan awo ati ohun elo gasiketi jẹ pataki paapaa.
Aṣayan ohun elo awo ti paarọ ooru awo:
| Omi ti a sọ di mimọ, omi odo, epo ti o jẹun, epo ti o wa ni erupe ile ati awọn media miiran | irin alagbara (AISI 304, AISI 316, ati be be lo). |
| omi okun, brine, salinization ati awọn miiran media | titanium ati titanium palladium (Ti, Ti-Pd) |
| Dilute sulfuric acid, dilute sulfur iyọ ojutu olomi ojutu, ojutu aqueous inorganic ati awọn media miiran | 20Cr, 18Ni, 6Mo (254SMO) ati awọn miiran alloys |
| Iwọn otutu ti o ga ati ifọkansi giga caustic onisuga alabọde | Ni |
| Sulfuric acid ogidi, hydrochloric acid ati phosphoric acid alabọde | Hastelloy alloy (C276, d205, B20) |
Aṣayan ohun elo ti gasiketi fun oluyipada ooru awo:
Pupọ eniyan mọ pe awọn epo lilẹ roba jẹ awọn ohun elo ti a lo nigbagbogbo, gẹgẹbi EPDM, roba nitrile, roba nitrile hydrogenated, fluororubber ati bẹbẹ lọ.
| EPDM | Iwọn otutu iṣẹ jẹ - 25 ~ 180 ℃.O dara fun omi ti o gbona alabọde omi, nya si, osonu oju aye, epo epo ti ko ni epo, acid alailagbara, ipilẹ alailagbara, ketone, oti, ester, bbl |
| NBR | Iwọn otutu iṣẹ jẹ - 15 ~ 130 ℃.O dara fun ọpọlọpọ awọn ọja epo nkan ti o wa ni erupe bi alabọde omi, epo epo ina, epo lubricating, eranko ati epo ẹfọ, omi gbona, omi iyọ, ati bẹbẹ lọ. |
| HNBR | Iwọn otutu iṣẹ jẹ - 15 ~ 160 ℃.O dara fun omi iwọn otutu alabọde omi, epo robi, epo ti o ni sulfur ati awọn agbo ogun ti o ni imi-ọjọ imi-ọjọ, diẹ ninu awọn epo gbigbe ooru, refrigerant R134a tuntun ati agbegbe osonu. |
| FKM | Iwọn otutu iṣẹ jẹ - 15 ~ 200 ℃.O dara fun alabọde ito, gẹgẹbi sulfuric acid ogidi, omi onisuga caustic, epo gbigbe ooru, epo epo oti, epo epo acid, nya iwọn otutu giga, omi chlorine, fosifeti, bbl |
