1. Ukunyamezela iimpompo zamabakala ahlukeneyo achanekileyo
Inqanaba lokuchaneka kwempompo alinakukhethwa kwaye limiselwe kuphela ngokwenqanaba lokuchaneka komsonto oza kusetyenziswa ngoomatshini, Kufuneka kwakhona kuqwalaselwe:
(1) izinto kunye nobunzima bomsebenzi oza kwenziwa;
(2) Izixhobo zokucofa (ezifana neemeko zesixhobo somatshini, izibambo zesixhobo sokugoba, amakhonkco okupholisa, njl.);
(3) Ukuchaneka kunye nempazamo yokwenziwa kwempompo ngokwayo.
Umzekelo: ukucutshungulwa kwentambo ye-6H, xa kucutshungulwa kwiindawo zentsimbi, i-tap ye-6H echanekileyo inokukhethwa;Ekusetyenzweni kwentsimbi engwevu, ngenxa yokuba i-diameter ephakathi yempompo inxiba ngokukhawuleza, ukwandiswa kwe-screw hole kuncinci, ngoko ke kufanelekile ukukhetha impompo echanekileyo ye-6HX, ubomi buya kuba ngcono.
Inkcazo yokuchaneka kwempompo ye-JIS:
(1) I-OSG yokusika itephu isebenzisa inkqubo ye-OH yokuchaneka, eyahlukileyo kwimigangatho ye-ISO, inkqubo ye-OH echanekileyo iya kunyanzela ububanzi bendawo yonke yokunyamezela ukusuka kumda ophantsi, yonke i-0.02mm njengenqanaba lokuchaneka, elibizwa ngokuba yi-OH1, OH2, OH3, njl. ;
(2) I-OSG ye-extrusion tap isebenzisa inkqubo yokuchaneka kwe-RH, inkqubo yokuchaneka kwe-RH inyanzelisa ububanzi bendawo yonke yokunyamezela ukuqala ukusuka kumda ophantsi, yonke i-0.0127mm njengenqanaba lokuchaneka, eligama linguRH1, RH2, RH3 njalo njalo.
Ngoko ke, xa usebenzisa i-ISO yempompo yokuchaneka ukuze ithathe indawo ye-OH yempompo yokuchaneka, ayinakuqwalaselwa ngokulula ukuba i-6H imalunga ne-OH3 okanye i-OH4 inqanaba, ekufuneka igqitywe ngokuguqulwa, okanye ngokuhambelana nemeko yomthengi.
2. Ubungakanani bangaphandle bempompo
(1) Okwangoku, ezona zisetyenziswa kakhulu yi-DIN, ANSI,ISO, JIS, njl.;
(2) Khetha ubude obufanelekileyo obupheleleyo, ubude be-blade kunye nokuphatha ubungakanani besikwere ngokweemfuno ezahlukeneyo zokucwangcisa okanye iimeko ezikhoyo zabathengi;
(3) Ukuphazamiseka ngexesha lokucubungula.
3. Izinto ezi-6 ezisisiseko zokukhetha impompo
(1) Uhlobo lokucutshungulwa kwentambo, i-metric, iBritane, iMelika, njl.;
(2) Uhlobo lomngxuma ongezantsi womsonto, ngomngxuma okanye umngxuma oyimfama;
(3) Izinto kunye nobunzima bomsebenzi oza kwenziwa;
(4) Ubunzulu bomsonto opheleleyo womsebenzi kunye nobunzulu bomngxuma osezantsi;
(5) Ukuchaneka okufunwa ngumsonto womsebenzi;
(6) Ubume umgangatho wempompo.
