Kuti tione kuti mashandiro emapatya eferrule chubhu fittingsmaererano nekudzivirira ngura, kuvhara, kuramba kumanikidzwa uye kuramba kudedera, takatora sampuli dzezvigadzirwa kubva mumapoka akasiyana zvichienderana nezvinodiwa.ASTM F1387, ABSuye zvirevo zvemajoini emhando yenyukireya, uye vakaita bvunzo dzekuedza dzinotevera. Mhedzisiro yacho inoratidza kuti dzese dzakapasa.
Bvunzo yekuedza
| Chigadzirwa | Rudzi rwekuyedza | Maitiro ekuyedza | Mhedzisiro yebvunzo |
| Zvigadziko zvechubhu yeferrule mbiri | Kuyedzwa kwekudengenyeka | Bvunzo yekudedera inoitwa munzira dze X, Y uye Z dzechikamu chebvunzo zvakateerana. Kuwanda kwebvunzo kuri pakati pe4 ~ 33hz, uye hapana kubuda kwemvura panguva yebvunzo. | Pasi |
| Kuedzwa kwekumanikidzwa kweHydraulic proof | Nzvimbo yekuyedza ine mvura yakachena, kumanikidzwa kwekuyedza kwakapetwa ka1.5 pane kushanda, nguva yekubata kumanikidzwa kwacho imaminitsi mashanu, uye kuiswa kwacho hakuna kuchinja kana kubuda kwemvura. | Pasi | |
| Bvunzo rekudzivirira ngura | Kuedzwa kwemushonga wekuisa simbi isina ngura kwakaitwa kwemaawa zana nemakumi matanhatu nemasere, uye pakanga pasina nzvimbo yengura. | Pasi | |
| Kuedzwa kwekudzivirira kwepneumatic | Nzvimbo yekuyedza ine nitrogen, kumanikidzwa kwekuyedza kwakapetwa ka1.25 pane kushanda, uye kumanikidzwa kwacho kunochengetwa kwemaminitsi mashanu pasina kubuda kwemvura. | Pasi | |
| Kuedzwa kwepfungwa | Kumanikidzwa kwemoyo kunokwira kubva pa0 kusvika pa133% yekushanda, uye kunodzikisa kumanikidzwa kusvika pa20 ± 5% yekushanda kwakarongwa. Huwandu hwenguva yekumanikidzwa uye nguva yekurerutsa kumanikidzwa idenderedzwa. Mushure mekunge kutenderera kwacho kunonoka kanenge ka1000000, hapana kubuda kwemvura. | Pasi | |
| Kuyedza kupwanya nekusanganisazve | Kanenge kagumi kekupindirana kwemukati nekubatanidzwazve mukuyedza kwega kwega pasina kubuda kwemvura. | Pasi | |
| Kuyedzwa kwemhepo inopisa | Pasi pekumanikidzwa kushanda, chidimbu chekuyedza chinofanira kuchengetwa patembiricha yakaderera - 25 ℃ kwemaawa maviri, uye chidimbu chekuyedza chinofanira kuchengetwa patembiricha yepamusoro ye80 ℃ kwemaawa maviri. Kubva patembiricha yakaderera kusvika patembiricha yepamusoro pane kutenderera, kunogara kwemasekonzi matatu. Mushure mekuyedzwa kwe hydraulic, hapana kubuda kwemvura. | Pasi | |
| Bvisa bvunzo | Isa mutoro unorema usingachinjiki pakumhanya kweinenge 1.3mm/min (0.05in/min). Pakumhanya uku, svika pamutengo wemutoro unorema unobvumidzwa, ferrule haina kuparadzaniswa nechinhu chayo, uye hapana kubuda kwemvura kana kukuvara mu hydrostatic test. | Pasi | |
| Kuedza kuneta kwakakombama | 1. Muenzaniso unosvika pakukotamira kwesimba kunodiwa neF1387 pasi pekumanikidzwa kwekushanda kwakayerwa, 2. Nzvimbo kubva pazero change point kusvika pakakwirira positive strain, kubva pazero change point kusvika pakakwirira negative strain, uye kubva pazero change strain kusvika pakakwirira negative point idenderedzwa. 3. Ita madenderedzwa 30000 pachikamu chekuyedza, uye hapana kubuda kwemvura panguva yekuyedza. | Pasi | |
| Kuyedzwa kwekumanikidzwa kunoputika | Dzvinyirira chidimbu chekuyedza kanopfuura ka4 kumanikidzwa kwekushanda kusvika chubhu yaputika, uye maferrule acho asina kudonha kana kubuda mvura. | Pasi | |
| Kuyedzwa kwekutenderera kwekuchinja | 1. Isa nguva yekukotama zvichienderana neF1387 woivhara panzvimbo yayo. 2. Dzvinyirira chidimbu chekuyedza kusvika pakumanikidzwa kushoma kwe3.45mpa (500PSI). Ramba uchikombama uye uchimanikidzwa panguva yekuyedza. 3. Tenderedza chidimbu chekuyedza kweinenge 1000000 cycles nekumhanya kweinenge 1750 rpm, uye hapana kubuda kwemvura mu hydrostatic test. | Pasi | |
| Kuedza pamusoro pe torque | Batanidza chidimbu chekuyedza nechishandiso chakakodzera wotenderedza rimwe divi kusvika chubhu yachinja zvachose kana kuti yabviswa kana tichienzanisa nechinhu chayo uye pasina kubuda kwemvura mu hydrostatic test. | Pasi
