Mokhoa oa ho khetha lisebelisoa bakeng sa litiiso tsa mochini

Ho khetha thepa bakeng sa tiiso ea hau ke ea bohlokoa kaha e tla phetha karolo ea ho khetholla boleng, nako ea bophelo le ts'ebetso ea kopo, le ho fokotsa mathata nakong e tlang.

Khetho ea lisebelisoa tse sebelisoang hangata bakeng sa litiiso tsa mochini.

1. Metsi a hloekileng, mocheso o tloaelehileng. selikalikoe se tsamaeang: 9Cr18, 1Cr13, cobalt chromium tungsten e holimo, tšepe e entsoeng ka tšepe; Ring e tsitsitseng: resin e kentsoeng graphite, boronse, polasetiki ea phenolic.

2. Metsi a nōka (a nang le sediment), mocheso o tloaelehileng. Ring e matla: tungsten carbide;

Lesale la ho ema: tungsten carbide.

3. Metsi a leoatle, mocheso o tloaelehileng Moving ring: tungsten carbide, 1Cr13 surfacing cobalt chromium tungsten, cast iron; Ring e tsitsitseng: graphite e kentsoeng ka resin, tungsten carbide, cermet.

4. Metsi a futhumetseng ka likhato tse 100. selikalikoe se tsamaeang: tungsten carbide, 1Cr13, cobalt chromium tungsten holimo, tšepe e entsoeng ka tšepe; Ring e tsitsitseng: graphite e kentsoeng ka resin, tungsten carbide, cermet.

5. Peterole, oli e tlotsang, li-hydrocarbon tse metsi, mocheso o tloaelehileng. selikalikoe se tsamaeang: tungsten carbide, 1Cr13, cobalt chromium tungsten holimo, tšepe e entsoeng ka tšepe; Ring e tsitsitseng: e kentsoeng ka resin kapa tin-antimony alloy graphite, polasetiki ea phenolic.

6. Peterole, oli e tlotsang, hydrocarbon ea mokelikeli, selikalikoe sa 100 se tsamaeang: tungsten carbide, 1Cr13 e fetang cobalt chromium tungsten; Ring e tsitsitseng: boronse e kentsoeng kapa resin graphite.

7. Peterole, oli e tlotsang, li-hydrocarbon tse metsi, tse nang le likaroloana. Ring e matla: tungsten carbide; Lesale la ho ema: tungsten carbide.

Mefuta le tšebeliso ea lisebelisoa tsa ho tiisa Lisebelisoa tsa ho tiisa li lokela ho finyella litlhoko tsa mosebetsi oa ho tiisa. Ka lebaka la mecha ea litaba e fapaneng e lokelang ho tiisoa le maemo a fapaneng a ho sebetsa a lisebelisoa, lisebelisoa tsa ho tiisa li hlokeha ho ba le maemo a fapaneng a ho ikamahanya le maemo. Litlhoko tsa thepa ea ho tiisa ka kakaretso ke:

1. Thepa e na le sekhahla se setle 'me ha ho bonolo ho tsoa mecha ea litaba.

2. E-ba le matla a loketseng a mochine le boima.

3. Molemo compressibility le botsitso, nyenyane deformation sa feleng.

4. Ha e nolofatse kapa ha e bola ka mocheso o phahameng, ha e thata kapa ha e phunye ka mocheso o tlaase.

5. E na le khanyetso e ntle ea kutu 'me e ka sebetsa nako e telele ka acid, alkali, oli le mecha e meng ea litaba. Molumo oa eona le phetoho ea boima ba eona e nyenyane, 'me ha e khomarele holim'a tšepe.

6. Coefficient e nyane ea likhohlano le khanyetso e ntle ea ho apara.

7. E na le ho feto-fetoha ha maemo ho kopanya le sebaka sa ho tiisa.

8. Ho hanyetsa botsofali hantle le ho tšoarella.

9. Ho bonolo ho e sebetsa le ho e etsa, e theko e tlaase ebile e bonolo ho fumana thepa.

Rubber ke thepa e tiisang e sebelisoang haholo. Ntle le rabara, lisebelisoa tse ling tse loketseng tsa ho tiisa li kenyelletsa graphite, polytetrafluoroethylene le li-sealants tse fapaneng.
