Uma kucatshangelwa isimo sangempela sohwebo lwendwangu yokungenisa nokuthekelisa ngaphandle, kuhlelwe ukuthi kusetshenziswe amasampula ahlukene ukuqhathanisa nokuxoxa nge izinga lokushisa elithile kanye nomswakama, indawo yokuhlola, umehluko wengcindezi kanye nezinye izimo ze-ISO 9237 kanye ne-ASTM D737, khetha ukusebenziseka nezimo zokumela, bese usungula amazinga emboni afanelekile ohwebo lokungenisa nokuthumela ngaphandle.
Ukuqhathaniswa kwemiphumela yokuhlolwa
Imiphumela yendwangu yokuphefumula ihlobene eduze nendlela yokuhlola esetshenziswayo. Phakathi kwemiphumela yokuhlolwa etholwe kusetshenziswa izindinganiso ezine zezindlela zokuhlola ezihlukene: ISO 9237, GB/T 5453, ASTM D 737 kanye ne-JIS L 1096: ukungena komoya okuhlolwe ngokwe-GB/T 5453 ne-ISO 9237 kuyafana; ngokusho kwe-GB/T5453 (ISO 9237) ) Ukungena komoya okuhloliwe kuncane kakhulu; amandla okungena komoya ahlolwe ngokwe-JIS L1096 inkulu kakhulu; ukukwazi ukungena komoya okuhlolwe ngokwe-ASTM D737 kuphakathi nendawo. Lapho indawo yokuhlola ihlala ingashintshiwe, ukuvuthwa komoya kuyanda njengoba ukwehla kwengcindezi kukhuphuka, okuhambisana nokwehla kwengcindezi okuphindaphindekayo. Kafushane, kuphela ngokukhetha izindlela zokuhlola ezifanele ezisekelwe kuzici zomkhiqizo lapho ukuphefumula kwezindwangu kungahlolwa ngendlela efanele.
Incazelo enemininingwane yezinyathelo zokuhlola (kuthatha i-GB/T 24218-15 njengesibonelo)
Ukusampula kunqunywa ngokusekelwe kumazinga omkhiqizo noma ukubonisana nezinhlangano ezifanele. Okokusebenza kokuhlola okungahlola ngokuqondile izindwangu ezingalukiwe ezinosayizi omkhulu, okungenani izingxenye ezi-5 zendwangu engalukiwe enosayizi omkhulu zingakhethwa ngokungahleliwe njengamasampula okuhlolwa; ngemishini yokuhlola engakwazi ukuhlola amasampula osayizi abakhulu, isikhunta esisikayo noma isifanekiso singasetshenziswa (Sika okungenani amasampula ama-5 kasayizi ongu-100mmX100 mm).
Beka isampula kusuka endaweni evamile uye endaweni evamile yomoya ethobelana ne-GB/T6529 futhi ulungise umswakama ukuze ulingane.
Bamba unqenqema lwesampula ukuze ugweme ukushintsha isimo semvelo sendawo yokuhlola engalukiwe.
Beka isifanekiso ekhanda lokuhlola bese usilungisa ngesistimu yokubopha ukuze uvimbele ukuhlanekezela kwesifanekiso noma ukuvuza kwegesi emaphethelweni ngesikhathi sokuhlolwa. Uma kunomehluko ekungeneni komoya phakathi kwezinhlangothi zangaphambili nangemuva zesampula, uhlangothi lokuhlola kufanele luphawulwe embikweni wokuhlola. Ngezibonelo ezimboziwe, beka isifanekiso ngohlangothi olunamekwe phansi (lubheke ohlangothini lwengcindezi ephansi) ukuze uvimbele ukuvuza kwegesi emaphethelweni.
Vula iphampu ye-vacuum bese ulungisa izinga lokugeleza komoya kuze kube yilapho umehluko odingekayo ufinyelelwa, okungukuthi, 100Pa, 125Pa noma 200Pa. Kwamanye amathuluzi amasha, inani lokucindezela kokuhlola likhethwa kusengaphambili ngokwedijithali, futhi umehluko wengcindezi kuzo zombili izinhlangothi zembobo yokulinganisa uboniswa ngedijithali kuyunithi yokuhlola ekhethiwe ukuze kube lula ukufunda okuqondile.
Uma kusetshenziswa igeji yokucindezela, linda kuze kube yilapho inani lokucindezela elidingekayo lizinzile bese ufunda inani lokungena komoya ngamalitha ngesentimitha yesikwele isekhondi [L/(cm·s)].
