Ukuchongwa kweeKhowudi zoBheyitha ezingezizo ezisemgangathweni

 

Iibheringi ezingezizo ezisemgangathwenibhekisa kwiibheringi ezinobukhulu, ulwakhiwo, ukuchaneka, okanye iimfuno zobugcisa ezingahambelaniyo nemigangatho yesizwe (GB/T). Zihlala zenziwe ngokwezifiso ngokusekelwe kwimizobo yabathengi. Iimpawu zazo ziquka ukuguquguquka okuphantsi, ukusetyenziswa okuphambili kwizixhobo ezikhethekileyo okanye usetyenziso oluchanekileyo (njengezixhobo zonyango kunye neemoto ezikhethekileyo), kunye nenani elikhulu leemveliso zovavanyo lophando nophuhliso. Ngenxa yobukhulu bebhetshi encinci, iindleko zazo zemveliso kunye namaxabiso zihlala ziphezulu kuneebheringi eziqhelekileyo.

 

Kwabanyeiibheringi, abo ububanzi babo bangaphakathi okanye ububanzi bobubanzi bangaphandle (ubude) bungahambelani nemigangatho yamazwe ngamazwe efanelekileyo babizwa ngokuba ziibheringi ezingezizo ezisemgangathweni. Ikhowudi yebheringi engezizo ezisemgangathweni iqulethe ikhowudi esisiseko, ikhowudi yokuqala, kunye nekhowudi esemgangathweni. Ikhowudi esisiseko inamacandelo amabini: ikhowudi yemodeli kunye nomlinganiselo omele ubungakanani obusisiseko bebheringi.

 

1. Ikhowudi yoLuhlu lobungakanani

 

Kukho iindlela ezimbini zokumela ikhowudi yoluhlu lobungakanani.

 

1) Ububanzi obungaphandle okanye ubukhulu bebheri engeyiyo esemgangathweni budla ngokuchongwa kusetyenziswa uthotho lobubanzi okanye uthotho lobubanzi olusondeleyo kumgangatho, kwaye oonobumba X1, X2, X3 bongezwa emva kwekhowudi esisiseko.

 

2) Ububanzi bangaphakathi, ububanzi bangaphandle, kunye nobubanzi bebheyari engeyoyesiqhelo abunakuthelekiswa noluhlu lobungakanani obuqhelekileyo, ngoko ke bamelwa njengamanani angenasiphelo.

 

2. Ikhowudi yobubanzi bangaphakathi

 

Ikhowudi yobukhulu bobubanzi bangaphakathi imelwe ngolu hlobo lulandelayo: kwiidayamitha ezingaphantsi kwe-500mm, kusetyenziswa inombolo epheleleyo eyahlulwahlulwa yi-5, kwaye i-quotient yahlulwe yi-5 ukumela ikhowudi yayo. Ezinye iidayamitha zichazwa ngokuthe ngqo njengobubanzi bangaphakathi bokwenyani ngeemilimitha, kodwa kufuneka zahlulwe ngo-"/" kusetyenziswa ikhowudi yoluhlu lobungakanani obufanayo.

 

Ukongeza, iibheringi ezingezizo ezisemgangathweni zingabonakaliswa kusetyenziswa imilinganiselo yeempawu zokufakelwa kofakelo. Imilinganiselo yeebheringi ichazwa ngolu hlobo: "/inner diameter * outer diameter * width", kunye neeyunithi zobukhulu bokwenyani kwi-mm.
