Indlela yokukhetha izixhobo zokutywinwa koomatshini

Ukukhetha izinto eziphathekayo zokutywinwa kwakho kubalulekile njengoko kuya kudlala indima ekunqumeni umgangatho, ubomi kunye nokusebenza kwesicelo, kunye nokunciphisa iingxaki kwixesha elizayo.

Ukukhethwa kwezinto ezisetyenziswa ngokuqhelekileyo zokutywinwa komatshini.

1. Amanzi acocekileyo, ubushushu obuqhelekileyo. Umsesane oshukumayo: 9Cr18, 1Cr13, phezu kwecobalt chromium tungsten, intsimbi eyintsimbi; Umsesane omileyo: i-resin efakwe kwigraphite, ubhedu, iplastiki yephenolic.

2. Amanzi omlambo (aqulethe intlenga), ubushushu obuqhelekileyo. Umsesane onamandla: tungsten carbide;

Umsesane omileyo: tungsten carbide.

3. Amanzi olwandle, iqondo lobushushu eliqhelekileyo Umsesane wokuhamba: i-tungsten carbide, i-1Cr13 ejongene ne-cobalt chromium tungsten, intsimbi etyhidiweyo; Umsesane omileyo: i-graphite efakwe kwi-resin, i-tungsten carbide, i-cermet.

4. Amanzi ashushu kakhulu ama-100 degrees. Umsesane oshukumayo: i-tungsten carbide, i-1Cr13, i-cobalt chromium tungsten yokujonga phezulu, intsimbi etyhidiweyo; Umsesane omileyo: i-graphite efakwe kwi-resin, i-tungsten carbide, i-cermet.

5. Ipetroli, ioli yokuthambisa, iihydrocarbon ezingamanzi, ubushushu obuqhelekileyo. Umsesane oshukumayo: i-tungsten carbide, i-1Cr13, i-cobalt chromium tungsten yokujonga phezulu, intsimbi etyhidiweyo; Umsesane omileyo: ufakwe kwi-resin okanye i-tin-antimony alloy graphite, iplastiki yephenolic.

6. Ipetroli, i-oyile yokuthambisa, i-hydrocarbon engamanzi, i-100 degrees ezihamba ngeringi: i-tungsten carbide, i-1Cr13 ejongene ne-cobalt chromium tungsten; Umsesane omileyo: ubhedu olufakwe ngaphakathi okanye i-resin graphite.

7. I-petroli, i-oyile yokuthambisa, i-hydrocarbons engamanzi, equlethe amasuntswana. Umsesane onamandla: tungsten carbide; Umsesane omileyo: tungsten carbide.

Iindidi kunye nokusetyenziswa kwezixhobo zokutywina Izinto zokutywina kufuneka zihlangabezane neemfuno zomsebenzi wokutywina. Ngenxa yeendaba ezahlukeneyo zokutywinwa kunye neemeko zokusebenza ezahlukeneyo zezixhobo, izinto zokutywina ziyafuneka ukuba zibe nokuguquguquka okwahlukileyo. Iimfuno zemathiriyeli yokutywina ngokubanzi zi:

1. Izinto eziphathekayo zinobuninzi obuhle kwaye akulula ukuvuza imidiya.

2. Yiba namandla afanelekileyo omatshini kunye nobulukhuni.

3. Ukunyanzeliswa okulungileyo kunye nokuqina, ukuguqulwa okuncinci okusisigxina.

4. Ayithambisanga okanye ayiboli kumaqondo obushushu aphezulu, ayiqini okanye iqhekeke kumaqondo obushushu aphantsi.

5. Inokumelana ne-corrosion efanelekileyo kwaye inokusebenza ixesha elide kwi-asidi, i-alkali, ioli kunye nezinye imidiya. Umthamo wayo kunye nokutshintsha kobunzima buncinci, kwaye ayihambisani nomgangatho wesinyithi.

6. I-coefficient encinci ye-friction kunye nokumelana nokunxiba kakuhle.

7. Ine-flexibility yokudibanisa kunye nomphezulu wokutywina.

8. Ukumelana nokuguga okuhle kunye nokuqina.

9. Kulula ukusetyenzwa kunye nokwenziwa, ngexabiso eliphantsi kwaye kulula ukufumana imathiriyeli.

Irabha yeyona nto isetyenziswa ngokuqhelekileyo ukutywina. Ukongeza kwirabha, ezinye izinto ezifanelekileyo zokutywinwa zibandakanya igraphite, i-polytetrafluoroethylene kunye ne-sealants eyahlukeneyo.
