1. Munyu wekupfapfaidza bvunzo
Testing method:
Kuyedza kupfapfaidza munyu inzira yekukasira yekuyedza iyo inotanga atomize imwe yemvura yemunyu yobva yamwaya mubhokisi rekushisa rinogara rakavharika. Nokucherechedza kuchinja kwehosi yejojo mushure mekuiswa mubhokisi rekushisa nguva dzose kwenguva yakati, kupikisa kwekuora kwejoini kunogona kuratidzwa.
Evaluation maitiro:
Chiyero chinonyanyozivikanwa chekuongorora ndechekuenzanisa nguva inotora kuti maokisidhi aonekwe pajoinhi nemutengo unotarisirwa panguva yekugadzira kuti uone kana chigadzirwa chacho chakakodzera.
Semuyenzaniso, maitiro ekukodzera eParker hose fittings ndeyekuti nguva yekugadzira ngura chena inofanira kunge iri ≥ 120 maawa uye nguva yekubudisa tsvuku tsvuku inofanira kuva ≥ 240 maawa.
Ehe, kana ukasarudza simbi isina tsvina, haufanirwe kunetseka zvakanyanya nezve ngura nyaya.
2. Kuputika bvunzo
Testing method:
Kuputika bvunzo bvunzo inoparadza iyo inowanzo sanganisira zvakafanana kuwedzera kudzvanywa kweachangobva kudzvanywa hydraulic hose musangano mukati memazuva makumi matatu kusvika ku4 nguva yekunyanya kushanda kumanikidza, kuitira kuti uone kushoma kwekuputika kwekumanikidza kwehose assembly.
Evaluation maitiro:
Kana kudzvanywa kwebvunzo kuri pazasi pehudiki kuputika uye hose yakatosangana nezviitiko zvakaita sekudonha, kuputika, kubatana, kana kuputika kwepombi, inoonekwa seisina kukodzera.
3. Low tembiricha bending bvunzo
Testing method:
Muedzo wekukotama wepasi-tembiricha ndeyekuisa yakaedzwa hose hose mukamuri yekudziya-yakadzika, kuchengetedza tembiricha yekamuri yekudziya-yakadzika nguva dzese pane tembiricha yekushanda yakatsanangurwa papoipi, uye kuchengetedza hose iri mutsetse wakatwasuka. Muedzo unotora maawa makumi maviri nemana.
Mushure mezvo, bvunzo yekukotama yakaitwa pamusimboti shaft, ine dhayamita kaviri iyo shoma yekupeta radius yehose. Pashure pokunge kupeta kwapera, hose yacho yaibvumirwa kuti idzokere mutembiricha yekamuri, uye pakanga pasina makatsemuka aioneka papoipi. Ipapo, muedzo wokudzvinyirira wakaitwa.
Panguva ino, iyo yese yakaderera-tembiricha yekukotama bvunzo inoonekwa seyakakwana.
Evaluation maitiro:
Munguva yese yekuyedza, hose yakaedzwa uye zvine chekuita nazvo hazvifanirwe kuputika; Paunenge uchiitisa bvunzo yekumanikidza mushure mekudzorera tembiricha yekamuri, hose yakaedzwa haifanire kudonha kana kuputika.
Iyo yakaderera yakayerwa tembiricha yekushanda kune yakajairwa hydraulic hoses ndeye -40 ° C, nepo Parker yakaderera-tembiricha hydraulic hoses inogona kusvika -57 ° C.
4. Pulse test
Testing method:
Iyo pulse test ye hydraulic hoses ndeye yekufungidzira bvunzo yehupenyu hose. Matanho ekuedza ndeaya anotevera:
- Kutanga, kotamisa gungano repombi kuita 90 ° kana 180 ° angle uye uiise pane yekuedza mudziyo;
- jekiseni inoenderana bvunzo yepakati muhosi yeungano, uye chengetedza yepakati tembiricha iri pa100 ± 3 ℃ panguva yekuyedzwa kwekushisa kwepamusoro;
- Shandisa pulse pressure mukati memusangano wepombi, nekuedza kudzvinyirira kwe 100% / 125% / 133% yehuwandu hwekushanda kwekushanda kwegungano repombi. Iyo bvunzo frequency inogona kusarudzwa pakati pe0.5Hz uye 1.3Hz. Mushure mekupedza iyo inoenderana chiyero yakatarwa nhamba yemapulses , kuyedza kunopedzwa.
Iko kune zvakare yakakwidziridzwa vhezheni yepulse test - flex pulse test. Muedzo uyu unoda kugadzirisa imwe mugumo we hydraulic hose assembly uye kubatanidza imwe magumo kune yakachinjika inofamba mudziyo. Munguva yekuyedzwa, iyo inofambiswa magumo inoda kufamba ichienda nekudzoka pane imwe frequency
Evaluation maitiro:
Mushure mokuzadzisa nhamba inodiwa yemapulses, kana pasina kukanganisa mumusangano wepombi, inofungidzirwa kuti yakapfuura muedzo wepulse.
