Ulwelo lwekhromatografi yokukhangela ivalve yerubhi ye-ceramic amanzi endaweni

Ukutshintsha nini ivalve yokukhangela?
① "Ilahleko yeNkulumbuso" ebonakala xa inkqubo iqhuba ibonisa ukuba uxinzelelo lwenkqubo luphantsi kakhulu, lusezantsi kakhulu kunoxinzelelo lwangasemva olufunekayo ekusebenzeni rhoqo kwechromatography yolwelo.Ikakhulu ibangelwa kukungcoliseka kwevalve yokukhangela kwintloko yempompo, okanye amaqamza amancinci ahlala kwivalve yokutshekisha ekhokelela ekufakweni okungaguqukiyo.Ngeli xesha, into ekufuneka siyenzile kukwenza umzamo wokucima amaqamza amancinci ngokusebenza kwemizuzu emihlanu ye "Wet Prime".Ukuba esi sisombululo siyasilela, kufuneka sisuse ivalve yokujonga, kwaye siyicoce nge-ultrasonically ngamanzi angaphezulu kwe-80℃.Kucetyiswa ukuba utshintshe i-cartridge ye-valve ukuba ukucoca ngokuphindaphindiweyo kungasebenzi.

② Kuyavela ukuba kukho amaqamza kwintloko yempompo okanye ivalve yokukhangela xa uxinzelelo lwenkqubo luguquguquka kakhulu.Sinokusebenza "i-Wet Prime" kwimizuzu emi-5-10, ukuhlambulula iibhubhu ngesantya esiphezulu sokuhamba.Ukuba indlela engentla ayisebenzi, kufuneka siyisuse ivalve yokujonga, kwaye siyicoce nge-ultrasonically ngamanzi angaphezulu kwe-80℃.Kucetyiswa ukuba utshintshe i-cartridge ye-valve ukuba ukucoca ngokuphindaphindiweyo kungasebenzi.

③ Xa kukho ingxaki ngokwenziwa kwakhona kwenaliti yesixokelelwano, okokuqala jonga ixesha logcino.Ukuba kukho ingxaki ngexesha lokugcinwa, khangela ukuguquguquka koxinzelelo lwenkqubo kuqhelekileyo okanye akunjalo.Ngokuqhelekileyo, kwinqanaba lokuhamba kwe-1ml / min, uxinzelelo lwenkqubo yesixhobo kufuneka lube yi-2000 ~ 3000psi.(Kukho ukungafani komlinganiselo ngokuxhomekeke kwiindidi zekholamu zechromatographic kunye nezigaba ezihambahambayo.) Kuyinto eqhelekileyo ukuba ukuguquguquka koxinzelelo kungaphakathi kwe-50psi.Ukuguquguquka koxinzelelo lwenkqubo elinganayo kunye nelungileyo kungaphakathi kwe-10psi.Ngaphantsi kwemeko yokuba ukuguquguquka koxinzelelo kukhulu kakhulu, kufuneka sicinge ukuba kungenzeka ukuba i-valve yokutshekisha ingcolisekile okanye inamaqamza, emva koko sijongane nayo.

Usebenzisa nini ivalve yokukhangela i-ceramic?
Kukho umba wokuhambelana phakathi kwe-ruby check valve ye-2690/2695 kunye neempawu ezithile ze-acetonitrile.Imeko ethile kukuba: xa usebenzisa i-acetonitrile eyi-100%, ukuyishiya ubusuku bonke, kwaye uqhubeka nokuqalisa iimvavanyo ngosuku olulandelayo, akukho manzi aphuma kumpompo.Oku kungenxa yokuba umzimba wevalve yerubhi yokukhangela kunye nebhola yerubhi ziye zancamathelana emva kokuntywila kwi-acetonitrile ecocekileyo.Kufuneka sisuse ivalve yokutshekisha kwaye siyibethe kancinci okanye siyiphathe nge-ultrasonically.Xa ushukumisa i-valve yokukhangela kunye nokuva isandi esincinci, oku kuthetha ukuba i-valve yokukhangela ibuyela kwisiqhelo.Ngoku buyisela ivalve yokutshekisha.Uvavanyo lunokuthi lwenziwe ngesiqhelo emva kwemizuzu emi-5 "i-Wet Prime".

Ukuze ugweme le ngxaki kwiimvavanyo ezilandelayo, kuyacetyiswa ukuba usebenzise i-valve yokukhangela i-ceramic.
