Zeziphi iimvavanyo ezifuna ukwenziwa imibhobho yamanzi phambi kokuba umke kumzi-mveliso?

1. Uvavanyo lwesitshizi setyuwa

Indlela yokuvavanya:

Uvavanyo lwesitshizi setyuwa yindlela yovavanyo olukhawulezileyo oluthi kuqala lufake iiatomi kugxininiso oluthile lwamanzi anetyuwa kwaye emva koko lutshizwe kwibhokisi yobushushu evaliweyo. Ngokuqwalasela utshintsho kwi-hose joint emva kokufakwa kwibhokisi yeqondo lokushisa rhoqo ixesha elithile, ukunyanzeliswa kwe-corrosion ye-joint kunokubonakaliswa.

Iikhrayitheriya zoVavanyo:

Umlinganiselo oqhelekileyo wokuvavanya kukuthelekisa ixesha elithathayo ukuba i-oxides ibonakale kwi-joint kunye nexabiso elilindelekileyo ngexesha loyilo ukuze kuqinisekiswe ukuba imveliso ifanelekile.

Ngokomzekelo, iikhrayitheriya zokufaneleka kwe-Parker hose fittings kukuba ixesha lokuvelisa i-rust emhlophe kufuneka ibe ≥ iiyure ze-120 kwaye ixesha lokuvelisa i-rust ebomvu kufuneka ibe yi-≥ 240 iiyure.

Kakade ke, ukuba ukhetha izixhobo zentsimbi engenastainless, akufuneki ukhathazeke kakhulu malunga nemiba yokubola.

2. Uvavanyo lokuqhushumba

Indlela yokuvavanya:

Uvavanyo lokuqhushumba luvavanyo olutshabalalisayo olubandakanya ngokulinganayo ukunyusa uxinzelelo lwendibano entsha ye-hydraulic hose hose ngaphakathi kweentsuku ezingama-30 ukuya kuma-4 amaxesha oxinzelelo oluphezulu lomsebenzi, ukuze kumiselwe ubuncinci boxinzelelo lokuqhushumba kwendibano yombhobho.

Iikhrayitheriya zoVavanyo:

Ukuba uxinzelelo lovavanyo lungaphantsi koxinzelelo oluncinci lokuqhuma kwaye i-hose sele ifumene izinto ezifana nokuvuza, ukuqhuma, ukuxutywa kwe-joint, okanye ukugqabhuka kwe-hose, kuthathwa njengokungafanelanga.

3. Uvavanyo lokugoba lobushushu obuphantsi

Indlela yokuvavanya:

Uvavanyo lokugoba lobushushu obuphantsi kukubeka indibano ye-hose evavanyiweyo kwigumbi eliphantsi lobushushu obuphantsi, ukugcina ubushushu begumbi eliphantsi lobushushu obungaguqukiyo kwiqondo lokushisa elisezantsi elichazwe kwi-hose, kwaye ugcine i-hose kwindawo yomgca ochanekileyo. Uvavanyo luhlala iiyure ezingama-24.

Emva koko, uvavanyo lokugoba lwenziwa kwi-shaft engundoqo, kunye nobubanzi obuphindwe kabini ubuncinci be-radius yokugoba ye-hose. Emva kokuba kugqitywe ukugoba, umbhobho wavunyelwa ukuba ubuyele kwiqondo lokushisa, kwaye kwakungekho zintanda ezibonakalayo kwithumbu. Emva koko, uvavanyo loxinzelelo lwenziwa.

Ngeli xesha, lonke uvavanyo lokugoba lobushushu obuphantsi lubonwa luphelele.

Iikhrayitheriya zoVavanyo:

Ngethuba lenkqubo yonke yokuvavanya, i-hose evavanyiweyo kunye nezixhobo ezinxulumene nazo akufanele ziphule; Xa uqhuba uvavanyo loxinzelelo emva kokubuyisela ukushisa kwegumbi, i-hose evavanyiweyo akufanele ivuze okanye iphule.

Ubuncinci bobushushu bokusebenza kwimibhobho ye-hydraulic yesiqhelo yi--40 ° C, ngelixa i-Parker's low-temperature hydraulic hoses inokufikelela ku -57 ° C.

4. Uvavanyo lwe-Pulse

 

Indlela yokuvavanya:

Uvavanyo lwe-pulse ye-hydraulic hoses lolovavanyo oluqikelelweyo lobomi bombhobho. Amanyathelo okulinga ngala alandelayo:

  • Okokuqala, goba indibano yombhobho kwi-90 ° okanye i-180 ° angle kwaye uyifake kwisixhobo sokulinga;
  • Tofa i-medium test ehambelanayo kwindibano ye-hose, kwaye ugcine ubushushu obuphakathi kwi-100 ± 3 ℃ ngexesha lokuvavanya ubushushu obuphezulu;
  • Faka uxinzelelo lwe-pulse kwindawo yangaphakathi yendibano ye-hose, kunye noxinzelelo lovavanyo lwe-100% / 125% / 133% yoxinzelelo oluphezulu lokusebenza lwendibano ye-hose. Uvavanyo oluqhelekileyo lunokukhethwa phakathi kwe-0.5Hz kunye ne-1.3Hz. Emva kokugqiba umgangatho ohambelanayo inani elichaziweyo lemibhobho , uvavanyo lugqityiwe.

Kukho kwakhona inguqu ephuculweyo yovavanyo lwe-pulse - uvavanyo lwe-flex pulse. Olu vavanyo lufuna ukulungisa isiphelo esinye sendibano ye-hydraulic hose kunye nokudibanisa esinye isiphelo kwisixhobo esishukumayo esithe tye. Ngexesha lovavanyo, isiphelo esishukumayo sidinga ukuhamba ngasemva naphambili kwi-frequency ethile

Iikhrayitheriya zoVavanyo:

Emva kokugqiba inani elifunekayo lee-pulses, ukuba akukho ukungaphumeleli kwindibano ye-hose, kuthathwa ukuba iphumelele uvavanyo lwe-pulse.
