Ukuhlolwa kokuqina kwezinto zensimbi kuyindlela eyinhloko yokuhlola izakhiwo zazo zemishini futhi kubaluleke kakhulu. Ngokulinganisa amapharamitha anjengokuqina kokuqina, amandla okukhiqiza, kanye nokwelulwa, kulinganisa amandla okuthwala umthwalo wezinto kanye nezici zokuguqulwa kwepulasitiki. Kuhlinzeka ngesisekelo sokuphepha sokuklama kobunjiniyela futhi kuqinisekisa ukuthembeka kwesakhiwo. Kusebenza futhi njengethuluzi elibalulekile lokulawula ikhwalithi, kuqinisekisa ukuzinza kwezinqubo zokukhiqiza nokuqinisekisa ukuhambisana nezindinganiso zomhlaba wonke. Ngaphezu kwalokho, kungabikezela ingozi yokwehluleka kwezinto ngaphansi kwemithwalo eyinkimbinkimbi futhi kunikeze ukwesekwa kwedatha ebalulekile ekuthuthukisweni kwezinto ezintsha.
Okulandelayo ukuqhathanisa izindlela zokuhlola ukuthambekela kwe-amapayipi ensimbi athambilefuthiAmapayipi e-SML, kokubili okusiza ukuqinisekisa ikhwalithi yomkhiqizo kanye nokusetshenziswa kwesikhathi eside ezimweni ezahlukahlukene zangempela.
1. Izinhlobo Zesampula
Ubukhulu kanye nobubanzi benduku yokuhlola yamasampula ensimbi athambile yilena elandelayo:
| Uhlobo lokusakaza | Ububanzi obujwayelekile bebha yokuhlola (mm) | Ukuphambuka komkhawulo wobubanzi (mm) | Ukubekezelelana kobubanzi (mm) |
| Ubukhulu bodonga lwepayipi lensimbi elithambile (mm) e＜6 6≤e＜8 8≤e＜12 12≤e | 2.5 3.5 5.0 6.0 | ±0.06 | 0.03 |
| Amapayipi ensimbi angenawo amapayipi, izinto zokufaka, kanye nezesekeli: - Izibonelo zokuphonsa ezihlanganisiwe: - Amasampula okuphonsa ahlukanisiwe: Kumasampula anobukhulu obungu-12.5 mm, ubukhulu bokubumba kumele bube ngaphansi kuka-12 mm. Kumasampula anobukhulu obungu-25 mm, ubukhulu bokubumba kumele bube ngu-≥ 12 mm. | 5.0 6.0 12.0 noma i-14.0 | ±0.06 ±0.06 ±0.09 | 0.03 0.03 0.04 |
Qaphela: Ibha yokuhlola yenziwe ngesampula eyenziwe ngomshini, emele insimbi ekujikeni okuphakathi kwesampula. Ifaka ingxenye eyindilinga. Ububanzi besilinda buboniswe kuthebula elingenhla. Ubude begeyiji yebha yokuhlola okungenani buphindwe kahlanu ububanzi bayo. Ukuphela kwebha yokuhlola kufanele kufane nokufakwa endaweni yomshini wokuhlola. Ubulukhuni bomphezulu wengxenye eyindilinga yebha yokuhlola yi-Rz ≤ 6.3.
Ipayipi le-SML lenziwe ngensimbi empunga futhi isampula yalo kufanele ivumelane nesibalo esilandelayo:
Qaphela: Ukuze uthole imiphumela yokuhlolwa emele umkhiqizo oqediwe ngangokunokwenzeka, isampula yokuhlola kufanele ithathwe epayipini le-SML noma ekufakweni kwe-SML bese isikwa ihambisane ne-axis yepayipi noma ekufakweni. Indawo yokuqala yesigaba esiphambeneyo sesampula kufanele ikalwe. Ububanzi nobukhulu besigaba esiphambeneyo kumele kulinganiswe ngokunembile ku-0.1mm ngaphambi kokuhlolwa.
2. Umehluko enkambisweni yokuhlola
Nakuba kokubili ukuhlolwa kokudonsa kwenziwa kusetshenziswa umshini wokuhlola ukudonsa ojwayelekile, izinto ezisetshenziswayo zihlukile.Isici sokuhlola ukuthamba kwensimbi ethambile siboniswe ngezansi:
Ipayipi le-SML kanye ne-fitting tensile test fitting kuboniswe ngezansi:
3. Umehluko phakathi kwemiphumela yokuhlolwa kanye nezakhiwo zezinto ezibonakalayo
Inqubo yokuncibilikisa nokukhiqiza insimbi ethambile ingumkhiqizo weminyaka yokuqongelela ubuchwepheshe kanye nokuziphatha okuqinile kokusebenza. Inkampani yethu ikhiqiza amapayipi ensimbi ethambile asezingeni eliphezulu, anezinga lokushintshashintsha kwama-spheroid elingu-90% noma ngaphezulu. Ukuhlolwa kokudonsa kwembula amandla okudonsa aphakathi kuka-460MPa no-490MPa, kanye nokwelulwa okuphakathi kuka-10% no-17%. Ngokwezindinganiso ze-EN545 kanye ne-ISO2531, amandla okudonsa angu-420MPa noma ngaphezulu kanye nokwelulwa okungu-5% kuya ku-10% noma ngaphezulu kubhekwa njengokwamukelekayo. Amandla okudonsa ajwayelekile kanye nokwelulwa kungokulandelayo:
Amapayipi e-SML kanye nokufakwa kwawo kwenziwa kakhulu ngensimbi empunga. Isakhiwo se-graphite esiphundu ngaphakathi kwensimbi empunga simunca ukudlidliza kwamanzi, okuholela emazingeni omsindo wokukhipha amanzi okungenani angu-10dB ngaphansi kwamapayipi e-PVC. Aphinde anikeze ukumelana okuhle kakhulu nokushisa okuphezulu, okungaphezu kuka-1,000°C. Amasongo enjoloba okuvala ahlala esebenza ngisho noma ku-70°C okuqhubekayo noma ukukhishwa okungahleliwe okungu-120°C, kanti ukuguquguquka kokushisa kuphela ingxenye yesikhombisa kunamapayipi e-PVC. Aphinde anikeze amandla amahle kakhulu okubamba, ukumelana nokushayisana, kanye nokumelana nokuklwebheka, okungenani izikhathi ezinhlanu kunamapayipi e-PVC.
Ngokwezinga le-EN877, izakhiwo zemishini zamapayipi e-SML kanye nokufakwa kwazo yilezi ezilandelayo:
| Uhlobo lokusakaza kanye nezinto zokwakha | Amandla amancane okudonsa (Mpa) |
| Ipayipi: Insimbi empunga | 200 |
| Ukufaneleka: Insimbi empunga | 150 |
Amapayipi e-SML kanye nokufakwa kwawo, amapayipi e-PVC, ukuhlolwa kokuthamba kwepayipi le-SML le-EN877, ukufakwa kwe-SML, amapayipi ensimbi e-ductile ye-EN545 ISO2531 kanye namapayipi e-SML, amasampula ensimbi e-ductile, ipayipi le-SML, ipayipi lensimbi elimpunga,
Isikhathi sokuthunyelwe: Septhemba-22-2025
