Ukudityaniswa koxinzelelo oluphezulu lwe-630 Bar yeeNkqubo zeHydraulic

I-ISO 15171 iyahambelana. Umlinganiselo woxinzelelo olungavuziyo, iisampulu yolwelo, kunye nokufumana umoya wesekethe ukuya kuthi ga kwi-630 bar. Ubungakanani bentambo obulungisekayo, imathiriyeli yokutywina, kunye neentsimbi zomzimba.

Yintoni iHydraulic Test Coupling?

I-hydraulic test coupling (ekwabizwa ngokuba yi-  diagnostic coupling  okanye  indawo yokuvavanya ) i-compact fitting efakwe ngokuthe ngqo kwisekethe ye-hydraulic. Inika i-port yokufikelela esemgangathweni apho unokudibanisa i-gauge ye-pressure gauge, i-hose yokuvavanya, okanye i-probe yesampuli ngemizuzwana-akukho kuvalwa, akukho khefu lomgca, akukho kulahleka kwamanzi.

Itywina langaphakathi le-poppet-style lihlala livaliwe de umbhobho wovavanyo lokukhwelana ulityhale livuleke. Olu luyilo  olungavuziyo  luthetha ukuchitheka kweqanda ngexesha lokuqhagamshelwa kunye noqhawulo, nkqu noxinzelelo olusondela kumda obekiweyo.

I-ISO 15171:  Ezi zidibanisi zovavanyo zihambelana ne  -ISO 15171-1  (ubukhulu kunye neemfuno zokusebenza kwii-screw-in test points) kunye ne  -ISO 15171-2  (i-mating test hose end fittings). Lo mgangatho wamazwe ngamazwe uqinisekisa ukutshintshiselana kwe-dimensional kubo bonke abavelisi - ithumbu elifanayo lovavanyo lilingana nokudityaniswa kweParker, Stauff, Hydac, Minimess, kunye nabanye.

Iimeko eziqhelekileyo zokusetyenziswa:

• Iitshekhi zokugunyazisa  - Qinisekisa uxinzelelo lwenkqubo ngexesha lokuqalisa

• Ukubeka iliso rhoqo  - Ukukhangela indawo ngokukhawuleza ngaphandle kokuphazamisa imveliso

• Isampuli ye-Fluid  - Khipha iisampulu zeoyile zohlalutyo longcoliseko

• Ukukhutshwa kwenkqubo  - Khupha umoya ovalelweyo emva kokugcinwa

IiNgcaciso eziphambili

uQhagamshelwano lweZibuko kunye neNdlela yokutywina

Eli candelo lijongana nezona zigqibo zimbini zibalulekileyo zobunjineli: indlela ukudibanisa okunxibelelana ngayo kwisekethe yakho, kwaye yintoni eyigcina itywiniwe phantsi koxinzelelo.

Iinketho zobungakanani bomsonto

Izikrufu zokudibanisa ngqo kwizibuko elicofayo kwi-hydraulic manifold yakho, isilinda, okanye ivalve block. Tshatisa umsonto kwizibuko elikhoyo - imisonto engahambelaniyo ibangela ukuvuza kwaye yonakalise iindawo zombini.

I-M16x2  yeyona sayizi idla ngokuodolwa kwimizi-mveliso jikelele.  I-G1 / 4  kunye ne  -G1 / 2  ilawula kwimimandla apho i-BSP yokuthunga iyinto eqhelekileyo (i-UK, i-Commonwealth, izityalo ezindala zaseYurophu).

Indlela yeTywina yaNgaphakathi

Umsebenzi ongavuziyo uxhomekeke kwivalve yepoppet eyenziwe ngokuchanekileyo ngaphakathi kumzimba odibanisayo:

1. Ekuphumleni  - I-spring-loaded poppet itywina ngokuchasene nesihlalo sangaphakathi. Uxinzelelo lwenkqubo lubamba ipapa ivalwe ngqongqo.

2. Ukudibanisa  - Isiphelo sombhobho wovavanyo lokukhwelana (ngokwe-ISO 15171-2) sicinezela i-poppet, sivula isicatshulwa kwigeji yakho okanye isampuli. Isitywina phakathi kokuphela kombhobho kunye ne-coupling bore kuthintela ukuvuza kwangaphandle.

3. Ukuqhawula  - Xa isiphelo se-hose sihoxisa, i-spring force ivala i-poppet ngoko nangoko. I-oyile eseleyo kwizibuko ihlala ngaphakathi - zero drip.

Ikhompawundi yetywina (i-NBR, i-FKM, i-EPDM, okanye i-low-temp) yenza umqobo ophambili phakathi kwe-poppet kunye nesihlalo, kunye nomqobo wesibini phakathi kwe-hose end taper kunye ne-coupling's bore yangaphakathi. Ukukhetha imathiriyeli yokutywina echanekileyo yobushushu bakho bolwelo kunye nekhemistri igutyungelwe kwi isikhokelo sokukhetha  ngezantsi.

Kutheni Khetha ezi 630 Bar Test Couplings?

Ibha ye-630 - Umlinganiselo ovavanyiweyo, hayi ukuthengisa

I-630 bar (i-9,135 psi) yingcinezelo yokusebenza eqinisekisiweyo kwiiprothokholi zokuvavanya ze-ISO 15171-1. Ubumbeko ngalunye lufumana uvavanyo loxinzelelo lwebhayisikile kunye nokuqinisekiswa komthwalo wobungqina ngaphambi kokukhululwa kwisitokhwe.

Usetyenziso oluqhelekileyo

Imibuzo ebuzwa qho

Ngaba i-630 yovavanyo lwebha yokudibanisa ikwazi ukuphatha inkonzo yegesi?

Uyilo olusemgangathweni lwe-ISO 15171 lulungiselelwe ioyile esebenza ngoxinzelelo lwendalo kunye nolwelo olusekwe kwiminerali. Kumoya oxinzelelweyo okanye enye imidiya yegesi, ijometri yokutywina yangaphakathi ayinakubonelela ngokusebenza okwaneleyo kokuvuza ngenxa ye-viscosity ephantsi yeegesi. Ukuba isicelo sakho sibandakanya inkonzo yerhasi, cacisa oku ngexesha lomyalelo ukuze sikwazi ukuvavanya ezinye iikhompawundi zetywina kwaye siqinisekise ukuhambelana kwemathiriyeli yomzimba kuxinzelelo lwakho lokusebenza oluthile.

Uthini umahluko phakathi kwe-304 kunye ne-316L yensimbi engenasici yokudibanisa uvavanyo?

Umahluko ophambili ngumxholo we-molybdenum. I-304 SS imalunga ne-18% yechromium kunye ne-8% nickel, ebonelela ngokuxhathisa okusemgangathweni kokutya kwiindawo ezomileyo zangaphakathi ngexabiso eliphantsi. I-316L SS yongeza i-2-3% ye-molybdenum, ephucula kakhulu ukuchasana ne-chloride-induced pitting kunye ne-crevice corrosion. Kwimekobume yaselwandle, ufakelo oluselunxwemeni, iindawo zokuhlanjwa kweekhemikhali, okanye nasiphi na isicelo esivezwe kwisitshizi setyuwa okanye i-icing salts, i-316L lukhetho olucetyiswayo ngaphandle kweendleko eziphezulu zemathiriyeli.

Ngaba ndingawufumana umzobo welogo yesiko kwiindibano zam zovavanyo?

Ewe. Sebenzisa ikhowudi yokumakisha XX kwinxalenye yenombolo yomtya kwaye ungenise ifayile yelogo yevector (AI/EPS/PDF ifomathi ekhethwayo). I-logo ibhalwe nge-laser kwiyunithi nganye ngaphambi kokuthunyelwa. Ubuncinci besayizi yebhetshi yokumakisha ngokwesiko iyahluka ngokwevolumu ye-odolo iyonke - ifumaneka ngokuqala kwiiyunithi ezingama-50 nge-SKU nganye.

Ngaba ndiyayidinga i-anti-vibration O-ring kulo lonke udibaniso lovavanyo?

Akunjalo rhoqo. I-anti-vibration O-ring (ikhowudi ye-1 kwinombolo yenxalenye) yongeza uphawu lokugcinwa kwesibini phakathi komzimba ofanelekileyo kunye nokufakwa kwentambo. Kucetyiswa ngamandla kwisixhobo esifumana ukungcangcazela okuqhubekayo ngaphezulu kwe-5 Hz - njengeempompo zepiston, iicompressor zedizili, ii-excavators ezihambayo, okanye iinkqubo zokuhambisa ezingcangcazelayo. Kufakelo olumileyo olufana neendawo zovavanyo lwaselabhoratri okanye oomatshini bokushicilela abamileyo, uguqulelo oluqhelekileyo ngaphandle kwe-O-ring lukholisa ukukwanela.

Zeziphi iisayizi zomsonto ezikhoyo kwi-630 bar test couplings?

Ukufumaneka okusemgangathweni kugubungela imisonto ye-metric M10x1, M12x1.5, M14x1.5, M16x2, M18x1.5, kunye ne-BSP imisonto ehambelanayo G1/4, G3/8, G1/2. Ubukhulu obuchazwe ngokuqhelekileyo yi-M10x1 (ii-compact circuits), i-M16x2 (i-standard industrial hydraulics), kunye ne-G1 / 2 (iinkqubo ezihamba phambili). Imisonto yesiko engaphandle kolu luhlu inokuveliswa ngokuxhomekeke kubungakanani bomyalelo ophantsi.

Ndingazikhetha njani imathiriyeli yokutywina eyiyo kwisixokelelwano sam samanzi aphantsi komhlaba?

Qala ngohlobo lwakho lokwenyani lolwelo kunye nobushushu obuphezulu bokusebenza. I-NBR isebenzela ulwelo lwe-oyile esekwe kwi-oyile ukuya kuthi ga kwi-100 °C - oku kubandakanya malunga ne-70% yezicelo zefektri kwaye lolona khetho lunexabiso eliphantsi. Tshintshela kwi-FKM ukuba inkqubo yakho isebenza ngaphezu kwe-100 °C okanye isebenzisa i-phosphate ester (ekwaziyo ukumelana nomlilo) ulwelo. Khetha i-EPDM ukuba usebenza nge-brake fluid, i-steam, imixube yamanzi-glycol, okanye i-polar synthetics. Kwiindawo ze-arctic okanye ze-cryogenic ezingaphantsi kwe-40 °C, cela i-compound ye-low-temp. Ukuqhuba itywina elingalunganga kwinkqubo yobushushu obuphezulu ngoyena nobangela wokuvuza kwangaphambi kwexesha.

Ngaba i-Zinc Nickel CrVI-free plating iyafuneka kwiimarike zaseYurophu?

Ayifunwa ngokungqongqo ngumthetho kuzo zonke iimveliso, kodwa kucetyiswa kakhulu. UMmiselo we-EU REACH (EC) No 1907/2006 unqanda ichromium enehexavalent kumphezulu wokugqitywa. I-zinc plating esemgangathweni ihlala iqulethe i-trace Cr (VI) i-passivation layers. I-Zinc Nickel CrVI-free plating isusa le mngcipheko wokuthotyelwa ngokupheleleyo ngelixa ihambisa iiyure ezingama-500 + zokuxhathisa ityuwa-spray nge-ASTM B117 - ingcono kakhulu kune-zinc eqhelekileyo. Kuyo nayiphi na imveliso ethunyelwe kwi-EU, i-CrVI-free sisincomo esingagqibekanga.

Yintoni i-ISO 15171 kwaye kutheni ibalulekile ekudibaneni kovavanyo?

I-ISO 15171 ngumgangatho wamazwe ngamazwe oquka ngokukodwa ukudityaniswa kovavanyo lwe-hydraulic ukuze kusetyenziswe iinkqubo zamandla alwelo. Icandelo loku-1 (ISO 15171-1) lichaza imilinganiselo, iimfuno zokusebenza, kunye neendlela zovavanyo zokudibanisa izikrufu. Icandelo lesi-2 (ISO 15171-2) libandakanya ukufakwa kombhobho wovavanyo lokukhwelana. Ukuthotyelwa kuthetha ukuba imveliso ihlangabezana nokutshintshiselana komgangatho ovunyiweyo kwihlabathi jikelele kunye nemigangatho yokukala uxinzelelo - kubalulekile xa isixhobo sakho sovavanyo kufuneka sijongane nezinto ezivela kubavelisi abohlukeneyo. Iimveliso ezidibana ne-ISO 15171 ngamanye amaxesha zibhekiswa kuzo kushishino njenge 'diagnostic coupling' okanye 'minimess' izifakelo zesitayile.
