Umgaqo wokusebenza:
Iimpompo ze-diaphragm ziqhutywa ngumoya oxinanisiweyo. I-valve yokuhambisa umoya yolwalathiso kunye ne-valve yesikhokelo, ebizwa ngokuba: igumbi lomoya, lihlelwe kwindawo ephakathi yempompo. Umthombo uqukuqela kwiityhubhu ezimbini zokuhlangana kunye negumbi elingaphandle le-diaphragm, elibizwa ngokuba ligumbi eliphakathi. Ngokuqhelekileyo iivalvu zokujonga (ibhola okanye idiski) zicwangciswe phezulu okanye ezantsi kwigumbi ngalinye langaphandle le-diaphragm okanye ukwabelana ngetyhubhu yokudibana. Amagumbi amabini angaphandle e-diaphragm adityaniswe ngokufunxa kunye nokuphuma kwamalungu, kwaye impompo iyaziqala. Ukusebenza, iivalve zokuhambisa umoya zilawula ngokuhlukileyo ukunyanzeliswa kwe-diaphragm nganye. Emva kokubetha ngalunye, ivalve iya kutshintsha ngokuzenzekelayo isikhundla, ukuze umoya utshintshelwe kwelinye igumbi le-diaphragm, ukuze amacala amabini egumbi le-diaphragm enze enye indawo yokufunxa kunye noxinzelelo lokutya, i-diaphragm ngokuhambelanayo ukuhamba endleleni. , ivalve yomoya akukho mfuno yeoli yokuthambisa ioyile, le yeyona ndlela ithandwayo yokusebenza; Umoya ococekileyo, owomileyo unokuphucula ukusebenza kwempompo.
Ivalve yomoya
Ivalve yokukhangela ivula kwaye ivale njengoko i-medium idlula kwimpompo. Oku kuvumela igumbi ngalinye le-diaphragm langaphandle ukuba lizaliswe kwaye likhutshwe ngokutshintshanayo. I-valve yokukhangela isabela kwiiyantlukwano zoxinzelelo. Iivalve zebhola ziyakwazi ukuphatha imidiya equkethe amaqhekeza amancinci, ngelixa i-disc check valves inokusingatha imidiya equkethe amaqhekeza athambileyo kufuphi nobubanzi bombhobho. Xa i-valve yokuhambisa umoya yenza umoya oxinzelelweyo ungene kwigumbi le-diaphragm lasekhohlo, i-diaphragm icinezelwe, kwaye i-stroke yokutya yoxinzelelo yenziwe. I-medium kwisebe lokutya loxinzelelo inyanzelekile ukuba ishiye i-diaphragm yangaphandle ye-diaphragm, i-valve yokutshekisha kunye netyhubhu ye-confluence, kwaye emva koko iphuma kwi-outlet yempompo. Indawo yokuphuma ingaba phezulu, ezantsi, okanye ecaleni. Xa igumbi lasekhohlo le-diaphragm lityhalwa ngaphandle phantsi koxinzelelo, intonga yokudibanisa i-diaphragm ngaphakathi idonsa i-diaphragm yasekunene ngaphakathi i-valve yokutshekisha ehoxisiweyo ukuze igcwalise ulwelo. Emva kokuba esi senzo sokujikeleza sigqityiwe, i-valve yokusabalalisa umoya iya kutshintsha ngokuzenzekelayo indawo yayo, ukuze umoya utshintshelwe kwelinye igumbi le-diaphragm, kwaye isenzo esijikelezayo esingentla siya kuphinda siphindwe ngasemva, oko kukuthi, amagumbi e-diaphragm kumacala omabini. ke ngoko bonisa ukutyiswa koxinzelelo olutshintshanayo kunye nesenzo sokufunxa ulwelo.
Ukufakela kunye nokuqalisa
Umpompo ubekwe ngokusondeleyo kwimveliso ngokusemandleni, ukwenzela ukuba umgca wokufunxa ufutshane, inani leenxalenye zokumisela liyancipha, musa ukunciphisa ukucaciswa kwemibhobho.
Ukwandisa ubomi be-diaphragm, gcina impompo ngokusondeleyo kumanzi ampontshwa ngokusemandleni, kwaye ufake idivaysi yokulungelelanisa uxinzelelo olucothayo ukwandisa ubomi be-diaphragm xa uxinzelelo lwe-inlet ludlula i-10 ft (3 m) ikholamu.
Ukuba kufakwe umbhobho oqinileyo, sebenzisa uqhagamshelwano olufutshane lombhobho phakathi kwempompo kunye nombhobho. Imibhobho inokucotha ukungcangcazela kunye nokuphazamiseka kumbhobho, kwaye i-stabilizer yoxinzelelo iyacetyiswa ukuba iqhubeke nokunciphisa i-pulses kumanzi.
Ukubonelela ngegesi
Uxinzelelo lokubonelela ngegesi aluyi kudlula i-125PSI (8.6BAR) kwiimpompo zetsimbi kunye ne-100PSI (6.9BAR) kwiimpompo zeplastiki. Xhuma i-inlet yomoya wepompo kumthombo womoya kunye nomthamo owaneleyo kunye noxinzelelo lokuhlangabezana neemfuno zoyilo. Ukuba umgca wokubonelela ngegesi ngumbhobho onzima, qhagamshela i-hose emfutshane phakathi kwepompo kunye nombhobho ukunciphisa ukuphazamiseka. Ukongeza kwi-cap yokungenisa umoya, ubunzima bombhobho wokungenisa umoya kunye nesihluzo sokulawula uxinzelelo kufuneka sixhaswe ngandlela-thile. Ukuba umbhobho awuxhaswanga, unokonakalisa umpompo. I-valve yokulawula uxinzelelo kufuneka ifakwe ukuqinisekisa ukuba uxinzelelo lokubonelela aludluli uluhlu oluchaziweyo.
Imiyalelo Phambi Kokusebenza
Ngaphambi kokuba ipompo isebenze, jonga zonke izinto ezizinzileyo zokuthintela ukubola, qinisa indawo ekhululekileyo ukuze ugweme ukuvuza, kwaye ulungise ngendlela echazwe kwikhadi elifakwe kwimpompo.
Thatha kwaye uqale
Xa uqala, vula ivalve yomoya malunga ne-1/2 ukuya kwi-3/4 ijika. Emva kokuba impompo iqalile, vula ivalve yomoya ukwandisa ukuhamba komoya ukufezekisa ukuhamba okufunekayo.
gqiba
Ukuba i-diaphragm iphukile, i-liquid ekhutshiweyo okanye igesi iya kungena kwi-air port yempompo kwaye ikhutshwe emoyeni. Xa izinto eziyingozi okanye eziyityhefu zitsalwa, kufuneka zifakwe ngombhobho kwindawo efanelekileyo ukuze zilahlwe ngokukhuselekileyo.
Ukuba ipompo ifakwe kwi-liquid operation, igesi kufuneka ikhutshwe kwindawo yamanzi, kwaye umbhobho wokukhupha akufanele ube ngaphantsi kwe-1 "(2.45CM). Ukunciphisa ubungakanani bombhobho wokukhupha kunciphisa ukuhamba kwegesi kunye nokunciphisa ukusetyenziswa kwempompo. Xa umgangatho wezinto eziphathekayo uphezulu kunempompo, i-outlet kufuneka ibe kwindawo ephezulu ukukhusela i-siphon phenomenon.
Kwiqondo elithile lobushushu kunye nokufuma, igesi egxothiweyo inokuba ngumkhenkce, kwaye ukusetyenziswa kwegesi yokomisa kunokuphelisa uninzi lwezi ngxaki.
Emva kokusetyenziswa
Ukuba isetyenziselwa ukuthutha izinto eziphilisiweyo ngokulula, ukwenzela ukukhusela umonakalo wepompo, emva kokusetyenziswa ngalunye ukucoca ngokucokisekileyo impompo. Emva kokusetyenziswa, imveliso eshiywe kwimpompo yomile okanye inamathele kumpompo, enokubangela ingxaki ye-diaphragm kunye ne-valve ngaphambi kokuqala okulandelayo. Kwiqondo lokushisa elibandayo, impompo kufuneka ikhutshwe emva kokusetyenziswa kuyo nayiphi na imeko.
Amanqaku okuthambisa ivalvu
