Ke mathata afe a lokelang ho lebisoa tlhokomelo ho khetho ea litiiso tsa rabara
Khetho ea litiiso tsa rabara e tlameha ho nahanela maemo a ho sebetsa, e le hore u khethe mokhoa o nepahetseng oa litiiso le thepa ea ho tiisa, mohaho oa ho kenya.
Khetho ea litiiso tsa rabara e hloka ho nahana ka maemo a sebetsang ka kakaretso a kenyelletsa: mocheso, khatello, bohareng.Tse ling li hloka ho kopanngoa le litšobotsi tsa thepa ka boeona ho nahana ka khetho ea litiiso.
Mabapi le mocheso, joalo ka ho tiisa lintho tse bonahalang NBR thepa sebetsa mocheso mefuta e fapaneng ka kakaretso -40 ~ +120 ℃.Ho feta 120 ℃ ho nahana ka tšebeliso ea FKM, esita le thepa ea PTFE, mocheso o tlase o batla o sa tloaeleha, ka kakaretso ho bua ka -20 ~ -40 ℃ ho nahana ka tšebeliso ea NBR e hanyetsanang le serame, NBR thepa ka kakaretso e tlaase. tikoloho mocheso tla lebisa ho thatafatsa lintho tse bonahalang, ho fella ka leakage, tse kang terene ea terene karolong e ka leboea ea mariha hangata hlaha mathata a joalo.
Ha e le khatello, e ama mofuta oa litiiso tse lokelang ho khethoa.Ka kakaretso, tšebeliso ea litiiso tsa rabara kapa PU bakeng sa khatello e tlase le khatello e mahareng e ke ke ea ba le bothata bo boholo haholo.Empa ho nahana ka bothata ba khatello ea tšusumetso, joalo ka mechini ea kaho qalong, e koaleha ha khatello ea eona e le kholo ho feta khatello e tloaelehileng ea ts'ebetso, ka hona hangata o tla khetha khatello ho fihla ho 70MPA e amang anti-squeeze HBY kapa SPGW joalo ka tiiso ea mantlha. .Litiiso tse kopaneng tsa PTFE le tsona ke khetho e tloaelehileng.
Bothata bo bohareng bo bonolo.Hlokomela mathata a manyane a khethehileng, joalo ka moqomo oa indasteri ea metallurgic hangata o sebelisa metsi-glycol le phosphate hydraulic fluid.Ka linako tse ling, le hoja mocheso o sebetsang o sa phahame, empa khetho ea thepa ea ho tiisa e lokela ho ba hlokolosi haholo, oli ea hydraulic e sebelisoa ha ho qetela kapa FKM.
Khetho ea litiiso ke ea bohlokoa haholo, kapa e tlameha ho kopanngoa le boemo ba thepa ka boeona ho khetha.
