Mavharuvhu akawanda eChinese anotengeswa kune dzimwe nyika dzakasiyana pasirese, uyezve vatengi vekunze vazhinji havanzwisise kukosha kwenhamba yevharuvhu yeChina, nhasi tichakuendesa kune imwe nzwisiso, tariro inogona kubatsira vatengi vedu.
MuChina, mhando dzemavharuvhu uye zvinhu zvakanyanya uye zvakanyanya, kugadzirira kwemhando dzevharuvhu zvakare kunowedzera uye kwakanyanya kuoma;mavharuvhu modhi anowanzo ratidza mhando yevharuvhu, modhi yekutyaira, fomu yekubatanidza, zvimiro zvechimiro, kudzvanywa kwezita, kuisa chisimbiso pamusoro pezvinhu, vharafu muviri zvinhu uye zvimwe zvinhu.Valve modhi yekumira yekugadzira dhizaini, kusarudzwa, kugovera, inopa nzira iri nyore yekubvumira vashandisi kutarisa zita rezita vachaziva chimiro cheimwe mhando yevharuvhu, zvinhu uye maficha.

Basa rekuzivikanwa kwevharuvhu
Kuzivikanwa kwevhavha mukushayikwa kwemifananidzo yevharuvhu, yakarasika zita rezita uye zvikamu zvevharuvhu hazvina kukwana, kushandiswa kwakakodzera kwemavharuvhu, zvikamu zvevhavha welding, kugadzirisa uye kutsiva zvikamu zvevharuvhu kwakakosha.Ikozvino chiratidzo chevharuvhu, kuzivikanwa kwezvinhu uye kuzivikanwa kwevharuvhu zvinotsanangurwa pazasi:
Kushandiswa kwe "basic knowledge yevharuvhu" yakadzidza ruzivo, maererano nezitaplate uye logo pavharuvhu uye vharafu paruvara rwependi.Iwe unogona kuona zvakananga chikamu chevhavha, chimiro chechimiro, zvinhu, dhayamita yezita, kumanikidzwa kwezita (kana kushanda nesimba), inoshanduka midhiya, tembiricha uye nzira yekuvhara.
1.Zita rezita rakagadziriswa pamutumbi wevharuvhu kana handwheel.Iyo data pane nameplate yakawedzera kuzara uye inoratidza iwo ekutanga maitiro evhavha.Maererano nemugadziri pane nameplate, kune mugadziri wevharuvhu akapfeka zvikamu zvemifananidzo uye ruzivo;maererano nezuva refekitari rekutarisa kugadzirisa;maererano nameplate inopa mamiriro ekushandiswa, kuona kutsiva gaskets, valve plate zvinhu uye mafomu pamwe nekuona kutsiva kwezvimwe zvikamu zvevharuvhu zvezvinhu.
2.Kumaka kunoshandiswa kukanda, kunyora uye dzimwe nzira muvharuvhu yemuviri inomaka vharafu zita rekumanikidza, kushanda kumanikidza, zita rekuti caliber uye yepakati kuyerera nzira.
3.Valve kune mhando yekumaka mirairo yakavhurika-yekuvhara, yakavhura chiyero chemutongi kana kuratidza kuvhurwa nekuvhara kwemuseve.Mavharuvhu eThrottle, mavharuvhu egedhi akasviba akanyorwa nemirairo yekuchinjisa kumucheto wepamusoro wevhiri reruoko akanyorwa nemuseve unonongedza munzira yekuvhura-kuvhara.
