Indlela yokukhetha izinto zokwakha zezimpawu zemishini

Ukukhetha impahla yophawu lwakho kubalulekile njengoba izobamba iqhaza ekunqumeni ikhwalithi, ubude besikhathi kanye nokusebenza kohlelo lokusebenza, kanye nokunciphisa izinkinga esikhathini esizayo.

Ukukhethwa kwezinto ezivame ukusetshenziselwa izigxivizo zemishini.

1. Amanzi ahlanzekile, izinga lokushisa elivamile. Indandatho ehambayo: 9Cr18, 1Cr13, i-cobalt chromium tungsten ehamba phambili, insimbi ecijile; Indandatho emile: i-resin efakwe i-graphite, ithusi, ipulasitiki ye-phenolic.

2. Amanzi omfula (aqukethe intlenga), izinga lokushisa elivamile. Indandatho enamandla: i-tungsten carbide;

Indandatho emile: i-tungsten carbide.

3. Amanzi olwandle, izinga lokushisa elivamile Indandatho ehambayo: i-tungsten carbide, i-1Cr13 i-cobalt chromium tungsten ehamba phambili, insimbi ekhonjiwe; Indandatho emile: i-resin-impregnated graphite, i-tungsten carbide, i-cermet.

4. Amanzi ashisa kakhulu ama-degree angu-100. Indandatho ehambayo: i-tungsten carbide, i-1Cr13, i-cobalt chromium tungsten engaphezulu, insimbi eyinsimbi; Indandatho emile: i-resin-impregnated graphite, i-tungsten carbide, i-cermet.

5. Uphethiloli, uwoyela wokugcoba, ama-hydrocarbon awuketshezi, izinga lokushisa elivamile. Indandatho ehambayo: i-tungsten carbide, i-1Cr13, i-cobalt chromium tungsten engaphezulu, insimbi eyinsimbi; Indandatho emile: efakwe inhlaka noma i-tin-antimony alloy graphite, ipulasitiki ye-phenolic.

6. Uphethiloli, uwoyela wokugcoba, i-hydrocarbon ewuketshezi, indandatho engu-100 enyakazayo: i-tungsten carbide, i-1Cr13 engaphezulu kwe-cobalt chromium tungsten; Indandatho emile: ithusi elifakwe ngaphakathi noma i-resin graphite.

7. Uphethiloli, amafutha okugcoba, ama-hydrocarbon awuketshezi, aqukethe izinhlayiya. Indandatho enamandla: i-tungsten carbide; Indandatho emile: i-tungsten carbide.

Izinhlobo nokusetshenziswa kwezinto zokuvala Izinto zokuvala kufanele zihlangabezane nezidingo zomsebenzi wokuvala. Ngenxa yemidiya ehlukene okufanele ivalwe kanye nezimo zokusebenza ezihlukene zemishini, izinto zokuvala ziyadingeka ukuze zibe nokuguquguquka okuhlukile. Izidingo zezinto zokuvala uphawu ngokuvamile ziyi:

1. Impahla inokuminyana okuhle futhi akulula ukuvuza imidiya.

2. Yiba namandla afanelekile nobulukhuni bemishini.

3. Ukucindezelwa okuhle nokuqina, ukuguqulwa okuncane okungapheli.

4. Ayithambisi noma ayiboli emazingeni okushisa aphezulu, ayiqini noma iqhekeke emazingeni okushisa aphansi.

5. Inokumelana nokugqwala okuhle futhi ingasebenza isikhathi eside ku-asidi, i-alkali, amafutha kanye neminye imidiya. Umthamo wayo kanye nokuguqulwa kokuqina kuncane, futhi akunamatheli endaweni yensimbi.

6. I-coefficient encane ye-friction kanye nokumelana okuhle kokugqoka.

7. Inokuvumelana nezimo ukuhlanganisa nendawo yokuvala.

8. Ukumelana nokuguga okuhle futhi kuhlala isikhathi eside.

9. Kulula ukucubungula nokukhiqiza, kushibhile futhi kulula ukuzithola izinto zokwakha.

Irabha iyinto esetshenziswa kakhulu yokuvala uphawu. Ngaphandle kwenjoloba, ezinye izinto ezifanele zokuvala zifaka i-graphite, i-polytetrafluoroethylene kanye nama-sealants ahlukahlukene.
