Mipaipi yachitsulo ya Hikelok imaphatikizapo payipi ya MF1 ndi payipi ya PH1. Chifukwa chakuti maonekedwe awo ndi ofanana, n’kovuta kuwasiyanitsa ndi maonekedwe awo. Choncho, pepala ili likuwunika kusiyana kwawo kuchokera kumapangidwe ndi ntchito, kuti athandize aliyense kumvetsetsa mozama za iwo ndikupanga chisankho choyenera kuphatikiza ndi momwe amagwirira ntchito pogula.
Kusiyana pakati pa payipi ya MF1 ndi payipi ya PH1
Kapangidwe
Zigawo zakunja za mndandanda wa MF1 ndi mndandanda wa PH1 zimapangidwa ndi 304 kuluka. Kuluka kwa kamangidwe kameneka kumawonjezera kupanikizika kwa payipi, komwe kumasinthasintha komanso kosavuta kupindika. Kusiyana kwagona pa zinthu za pachimake chubu awo. MF1 core chubu ndi 316L corrugated chubu, pomwe PH1 core chubu ndi yosalala yowongoka chubu yopangidwa ndi polytetrafluoroethylene (PTFE). (onani chithunzi chotsatirachi cha maonekedwe enieni ndi kusiyana kwa mkati)

Chithunzi 2 PH1 Hose
Ntchito
MF1 payipi yachitsulo imakhala ndi ntchito yabwino kwambiri pakukana moto, kukana kutentha kwambiri komanso kulimba kwa mpweya wabwino, chifukwa chake imagwiritsidwa ntchito nthawi zambiri kutentha kwambiri komanso nthawi za vacuum. Chifukwa cha mapangidwe azinthu zonse zachitsulo za payipi, kukana kwa dzimbiri kwa payipi kumakula bwino ndipo kulibe permeability. Pansi pa momwe ntchito ya corrosive transmission sing'anga imagwirira ntchito, imathanso kuonetsetsa kuti ikuyenda bwino komanso yokhazikika.
Monga chubu chapakati cha PH1 hose chimapangidwa ndi PTFE, chomwe chimakhala ndi kukhazikika kwamankhwala, kukana kwa dzimbiri, kukana kwa okosijeni, kutsekemera kwambiri, kusawoneka bwino, kukana nyengo komanso kuthekera koletsa kukalamba, payipi ya PH1 imagwiritsidwa ntchito nthawi zambiri potumiza. media zowononga kwambiri. Tikumbukenso kuti PTFE ndi permeable zinthu, ndipo mpweya udzadutsa mu voids mu zinthu. Kuthekera kwapadera kudzakhudzidwa ndi momwe ntchito zikuyendera panthawiyo.
Kupyolera mu kuyerekezera makhalidwe a ma hoses awiri omwe ali pamwambawa, ndikukhulupirira kuti mumamvetsetsa bwino ma hoses awiriwa, koma mfundo zotsatirazi ziyenera kuganiziridwa posankha mtundu:
Kupanikizika kwa ntchito
Sankhani payipi yokhala ndi kuthamanga koyenera malinga ndi momwe ntchito ikugwirira ntchito. Table 1 imatchula kukakamiza kogwira ntchito kwa ma hoses awiri omwe ali ndi mawonekedwe osiyanasiyana (m'mimba mwake mwadzina). Poyitanitsa, m'pofunika kufotokozera kupanikizika kwa ntchito pamene mukugwiritsa ntchito, ndiyeno sankhani payipi yoyenera malinga ndi mphamvu yogwira ntchito.
Table 1 Kuyerekeza kwa kukakamizidwa kwa ntchito
| Nominal Hose Kukula | Kupanikizika kwa Ntchito psi (bar) | |
| Mtengo wa MF1 | Mtengo wa PH1 | |
| -4 | 3100 (213) | 2800 (193) |
| -6 | 2000 (137) | 2700 (186) |
| -8 | 1800 (124) | 2200 (151) |

| -16 | 1200 (82.6) | 600 (41.3) |
| Zindikirani: Kuthamanga kogwira ntchito pamwambapa kumayesedwa pa kutentha kwapakati pa 20℃(70℉) | ||
Sing'anga yogwirira ntchito
Kumbali imodzi, mankhwala a sing'anga amasankhanso kusankha kwa payipi. Kusankha payipi molingana ndi sing'anga yomwe imagwiritsidwa ntchito kungapereke kusewera kwathunthu kwa payipi mpaka pamlingo waukulu ndikupewa kutayikira komwe kumachitika chifukwa cha dzimbiri lapakati mpaka payipi.
Table 2 Kuyerekeza kwazinthu
| Mtundu wa Hose | Core Tube Material |
| MF1 | 316l ndi |
| PH1 | PTFE |
MF1 mndandanda ndi payipi yachitsulo chosapanga dzimbiri, yomwe imakhala ndi kukana kwa dzimbiri, koma ndiyotsika kwambiri kuposa payipi ya PH1 pakukana kwa dzimbiri. Chifukwa cha kukhazikika kwa mankhwala a PTFE mu chubu chapakati, payipi ya PH1 imatha kupirira zinthu zambiri zama mankhwala, ndipo imatha kugwira ntchito mokhazikika ngakhale mukatikati mwa acid-base. Chifukwa chake, ngati sing'angayo ndi asidi ndi zinthu zamchere, payipi ya PH1 ndiyo yabwino kwambiri.
Kutentha kwa ntchito
Chifukwa zida zamachubu za MF1 hose ndi PH1 hose ndizosiyana, kukakamiza kwawo kumasiyananso. Sizovuta kuwona kuchokera patebulo 3 kuti payipi ya MF1 ili ndi kukana bwino kwa kutentha kuposa payipi ya PH1. Kutentha kukakhala kochepa kuposa - 65 ° F kapena kupitilira 400 ° F, payipi ya PH1 siyenera kugwiritsidwa ntchito. Panthawiyi, payipi yachitsulo ya MF1 iyenera kusankhidwa. Choncho, poyitanitsa, kutentha kwa ntchito ndi chimodzi mwazinthu zomwe ziyenera kutsimikiziridwa, kuti mupewe kutayikira kwa payipi panthawi yogwiritsira ntchito kwambiri.
Table 3 Kuyerekeza kwa kutentha kwa payipi
| Mtundu wa Hose | Kutentha kwa Ntchito℉ (℃) |
| MF1 | -325 ℉ mpaka 850 ℉ (-200 ℃ mpaka 454 ℃) |
| PH1 | -65 ℉ mpaka 400 ℉ (-54 ℃ mpaka 204 ℃) |
Permeability
MF1 mndandanda pachimake chubu chopangidwa ndi zitsulo, kotero palibe malowedwe, pamene PH1 mndandanda pachimake chubu amapangidwa PTFE, amene ndi permeable zakuthupi, ndi mpweya kudutsa kusiyana zinthu. Chifukwa chake, chidwi chapadera chiyenera kuperekedwa pamwambo wogwiritsa ntchito posankha payipi ya PH1.
Kutulutsa kwa medium
Pachimake chubu cha MF1 payipi ndi mvuto dongosolo, amene ali ndi kutsekereza ena zotsatira pa sing'anga ndi mkulu mamasukidwe akayendedwe ndi osauka fluidity. Chubu chapakati cha PH1 hose ndi chosalala chowongoka chowongoka, ndipo zinthu za PTFE zokha zimakhala ndi mafuta ambiri, motero zimathandizira kuyenda kwapakati komanso kosavuta kukonza ndi kuyeretsa tsiku ndi tsiku.
Kuphatikiza paMF1 kodindiPH1 gawo, Hikelok ilinso ndi PB1 hose ndipayipi yothamanga kwambirimitundu. Mukamagula ma hoses, mndandanda wazinthu zina za Hikelok zitha kugwiritsidwa ntchito limodzi.Zophatikiza ziwiri za ferrule chubu, zopangira mapaipi, mavavu a singano, ma valve a mpira, sampuli machitidwe, etc. angathenso makonda malinga ndi mikhalidwe yapadera ntchito.
Kuti mudziwe zambiri zoyitanitsa, chonde onani zomwe zasankhidwamabukupaWebusaiti yovomerezeka ya Hikelok. Ngati muli ndi mafunso osankhidwa, lemberani akatswiri ogulitsa malonda a Hikelok maola 24 pa intaneti.
