Nigute ushobora guhitamo ibikoresho bya kashe ya mashini

Guhitamo ibikoresho bya kashe yawe nibyingenzi kuko bizagira uruhare mukumenya ubuziranenge, igihe cyo kubaho nigikorwa cya porogaramu, no kugabanya ibibazo mugihe kizaza.

Guhitamo ibikoresho bisanzwe bikoreshwa mukidodo cya mashini.

1. Amazi meza, ubushyuhe busanzwe. Impeta yimuka: 9Cr18, 1Cr13, igaragara hejuru ya cobalt chromium tungsten, icyuma; Impeta ihagaze: resin yatewe inshusho, umuringa, plastiki ya fenolike.

2. Amazi yinzuzi (arimo imyanda), ubushyuhe busanzwe. Impeta idasanzwe: karubide ya tungsten;

Impeta ihagaze: karubide ya tungsten.

3. Amazi yo mu nyanja, ubushyuhe busanzwe Impeta yimuka: tungsten karbide, 1Cr13 igaragara cobalt chromium tungsten, icyuma; Impeta ihamye: resin-yatewe inshusho ya grafite, tungsten karbide, cermet.

4. Amazi ashyushye dogere 100. Impeta yimuka: karubide ya tungsten, 1Cr13, cobalt chromium tungsten igaragara, icyuma; Impeta ihamye: resin-yatewe inshusho ya grafite, tungsten karbide, cermet.

5. Benzin, amavuta yo gusiga, hydrocarbone y'amazi, ubushyuhe busanzwe. Impeta yimuka: karubide ya tungsten, 1Cr13, cobalt chromium tungsten igaragara, icyuma; Impeta ihagaze: yatewe hamwe na resin cyangwa tin-antimony alloy grafite, plastike ya fenolike.

6. Benzin, amavuta yo gusiga, hydrocarubone y'amazi, impeta ya dogere 100: karbide ya tungsten, 1Cr13 igaragara kuri cobalt chromium tungsten; Impeta ihagaze: umuringa watewe cyangwa resin grafite.

7. Benzine, amavuta yo gusiga, hydrocarbone y'amazi, irimo ibice. Impeta idasanzwe: karubide ya tungsten; Impeta ihagaze: karubide ya tungsten.

Ubwoko nogukoresha ibikoresho bya kashe Ibikoresho byo gufunga bigomba kuba byujuje ibisabwa mumikorere ya kashe. Bitewe nibitangazamakuru bitandukanye bigomba gufungwa hamwe nuburyo butandukanye bwibikorwa by ibikoresho, ibikoresho byo gufunga birasabwa kugira imiterere itandukanye. Ibisabwa mu gufunga ibikoresho muri rusange:

1. Ibikoresho bifite ubucucike bwiza kandi ntabwo byoroshye gusohora itangazamakuru.

2. Kugira imbaraga zumukanishi no gukomera.

3. Kwiyunvikana neza no kwihangana, guhindura ibintu bito bihoraho.

4. Ntiyoroshya cyangwa ngo ibore ku bushyuhe bwo hejuru, ntikomera cyangwa ngo isature ku bushyuhe buke.

5. Ifite ruswa irwanya ruswa kandi irashobora gukora igihe kirekire muri aside, alkali, amavuta nibindi bitangazamakuru. Ijwi ryayo nubukomezi bihinduka ni bito, kandi ntibifata hejuru yicyuma.

6. Coefficient ntoya yo guterana kandi irwanya kwambara neza.

7. Ifite uburyo bworoshye bwo guhuza hamwe nubuso bwa kashe.

8. Kurwanya gusaza neza kandi biramba.

9. Biroroshye gutunganya no gukora, bihendutse kandi byoroshye kubona ibikoresho.

Rubber nibikoresho bikoreshwa cyane. Usibye reberi, ibindi bikoresho bifunga kashe birimo grafite, polytetrafluoroethylene hamwe na kashe zitandukanye.
