Xa abantu abaninzi besiva 'iindawo zehomogenizer,' bacinga ngoko nangoko ngesivalo kunye nesitulo. Yiyo intliziyo yalo, ngokuqinisekileyo, kodwa ukulungisa loo nto kuphela kufana nokuthi i-injini yi-pistons nje. Umceli mngeni wangempela, kwaye apho iindleko kunye nexesha lokuphumla zihlala khona, kuyo yonke into exhasa ukusebenzisana koxinzelelo oluphezulu. Ndibone imisebenzi emininzi iodola isitakhi seevalvu ezitshintshwayo, kodwa bafumanisa ukuba ukuphuma kwabo kusenzima ngenxa yokuba bengakuhoyi ukunxiba amalungu homogenizer ngasentla—iiplanga, izitywini, nezivalo ezilawula uxinezeleko ngaphambi kokuba lubethe umsantsa. Yinkqubo, akukho nqaku elinye lokusilela.
Impahla Engabonakaliyo: IiPlanger kunye namatywina
Makhe sithethe ngeepunger. Iiplanga zeCeramic zisemgangathweni ngenxa yesizathu-ukumelana nokubola, ubunzima. Kodwa ba brittle. I-chip encinci yokungaphathwa kakuhle ngexesha lofakelo, okanye ukudinwa kukuqhekeka ukusuka kuxinzelelo loxinzelelo, kwaye unendlela evuzayo etshabalalisa ukupakisha amatywina kwiiyure, hayi iinyanga. Imowudi yokusilela ayisoloko igqabhuka iyintlekele; kudla ngokuba yilahleko kancinane yoxinzelelo oluleqa ngamanye amacandelo kuqala. Ndikhumbula isityalo sobisi sityhola isihlalo sevalve nge-emulsion embi, kodwa emva kokutshintsha kwezihlalo ezibini, ingxaki yaqhubeka. Umoni? Ukuqhekeka kweenwele kwiplunger onokuyibona kuphela phantsi kwesibane esinamandla. Uxinzelelo lwalusopha ngaphambi kokuba imveliso ifike kwi-valve ye-homogenizing.
Emva koko kukho amatywina kunye nokupakishwa. Le yi-tribology emsulwa. Akunjalo nje malunga nokuhambelana kwezinto kunye nemveliso (iikhemikhali ze-CIP zihlala zingumbulali wokwenene, kungekhona ubisi). Kumalunga nokuphela kweplunger ekhwela kuyo, ulungelelwaniso lwebhloko yempompo, kunye nemijikelo yobushushu. Ukupakishwa kwe-gland egxininisiweyo kuya kutshisa kakhulu kwaye kukhazimle i-ceramic plunger, ukudala amaqhekeza abrasive athi angcolise indawo yesitywina. Yi-cascade. Udinga umthengisi oqondayo oku kudlala, hayi nje omnye othengisela ibhegi yeetywini zegraphite eziqhelekileyo.
Apha kulapho i-Foundry kunye nevenkile yomatshini enamava ezinto ezinzulu iba baluleke kakhulu. Umzekelo, ukusebenza neqabane elinje Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) kwizindlu zesiko okanye endaweni yezindlu zeplanga okanye iibhloko zempompo ziqaqambisa ukubaluleka kwemfezeko yezinto. Bebekwi-casting kunye nomatshini iminyaka engaphezu kwama-30 (https://www.tsingtaocnc.com). Kwicandelo lokunxiba okuphezulu njengebhloko yempompo, umgangatho wokuphosa uyinto yonke. I-microscopic porosity kwi-alloy esuka kwi-inferior casting process iya kuba yindawo ye-nucleation yokukhathala, ekhokelela ekuqhekekeni phantsi kwe-10,000 psi pulsation rhoqo. Umsebenzi wabo ngeqokobhe kunye nokuphosa utyalo-mali kwiijiyometri ezintsonkothileyo, kunye nomatshini we-CNC wokwenza itywina elichanekileyo, liqinisekisa isiseko kwezo zibalulekileyo. amalungu homogenizer isandi.
INdibano yeVavu: Ngakumbi kuneJometri
Ivalve ye-homogenizing kunye nesihlalo. Ewe, kulapho kwenzeka khona umlingo. Kodwa ingcamango ephosakeleyo eqhelekileyo kukuba ijometri-i-angle, i-gap-kuphela kwenguqu. Ukuhambelana kwezinto eziphathekayo kubaluleke kakhulu. Isitulo esiqinileyo sentsimbi esingenasici ngokuchasene nobuso bevalve ye-tungsten carbide siqhelekile kubomi obude kwiimveliso ezirhabaxa. Kodwa ndibone iimeko apho umthengi watshintshela kwimveliso ene-asidi ephezulu kwaye akazange ayithathele ingqalelo le nto. Isiphumo yaba kukutya okukhawulezileyo kwegalvanic kumdibaniso, ukuvalela umphezulu kunye nokutshabalalisa ukusebenza kakuhle kwe-homogenization kwakudala ngaphambi kokuba ukunxitywa koomatshini kube ngumba.
Enye ingongoma efihlakeleyo: isiqu sevalve kunye nezikhokelo zayo. Eli candelo liqinisekisa ukuba i-valve iyanyuswa kwaye iphinda iphinde ibuyele ngokugqibeleleyo. Ukuba izikhokelo ziyanxiba, ivalve iyabhimba. Awufumani isithuba esicocekileyo, esifana nesonyaka; ufumana i-gap ephosakeleyo, i-tapered eyenza ukusabalalisa ubungakanani be-particle engahambelani kunye neehamile isihlalo ngokungalingani. Ukutshintsha isihlalo ngaphandle kokujongana nezikhokelo ezigugileyo yinkcitho yemali. Sisifundo esifunyenweyo ekuchitheni iiyunithi kunye nokufumana isihlalo 'esitsha' esele sibonisa ukunxitywa kwe-asymmetric emva kwexesha elifutshane.
Xa kufunwa ezi zinto, ukunyamezelana komatshini akukho nto ithethwayo. Ubuso bokutywina kufuneka bufakwe kwi-flatness ekufutshane ne-optical. Lo ayingomsebenzi wevenkile yoomatshini begeneric. Ifuna uhlobo lokuchaneka kwesakhono se-CNC ingcali kumacandelo oshishino enayo. Inkampani efana ne-QSY, egxininise kumatshini we-CNC weensimbi ezingenasici kunye ne-alloys ekhethekileyo, ilungiselelwe oku. Ukukwazi ukwenza umatshini we-cobalt okanye i-nickel-based alloys yokunxiba ngokugqithiseleyo okanye ukuxhathisa ukubola kumacandelo e-valve inokutshintsha umdlalo kwizicelo ezikhethekileyo ngaphaya kokutya, njengakumachiza okanye kwiikhemikhali.
Ukuva uxinzelelo kunye nokujonga iiValuvu
Ihlala ingahoywa kuluhlu lwamalungu ziivalvu zokujonga kwindawo yokungena nakwindawo yokuphuma. Umsebenzi wabo ubonakala ulula: ukuthintela ukubuyela emva. Kodwa xa beqala ukunxiba okanye ukudinwa kwemithombo yabo, babangela i-oscillations yoxinzelelo kunye nokudlula kwemveliso. Uya kuyibona kwigeyiji yoxinzelelo njengeflutter yenaliti. Oku kuzinziswa kubuyisela ivalve engundoqo ye-homogenizing, ibangela ukuba 'incokole' kwaye ikhawuleze ukuguga kubuso bevalve kunye nesitulo. Ukwakha ngokutsha okanye ukubuyisela ezi valves zokutshekisha luxabiso oluphantsi logcino lothintelo xa kuthelekiswa neendleko zeseti yevalvu entsha.
Izibuko zenzwa yoxinzelelo kunye neeplagi zezinye iindawo ezinengxaki. Ukuphinda-phinda umsonto wokulinganisa inzwa okanye ukutshintshwa kunokunxiba iintambo kwibhloko yempompo okanye ezininzi. Ekugqibeleni, ufumana ukuvuza ekunzima ukukulandela-inkungu entle yemveliso okanye amanzi. Ukuphinda ucofe kwaye ufake i-helical insert kukulungisa, kodwa lixesha lokuphumla. Ukusebenzisa i-annealed ngokufanelekileyo, i-high-integrity fittings kunye neebhloko ukusuka ekuqaleni, ezenziwe ngokucokisekileyo kunye nezinto ezenziwe ngoomatshini, kuthintela oku. I-robust casting, engenaziphene, iya kuba noxinaniso lwentsimbi olungaguqukiyo kwezi ndawo zinemisonto ephezulu yoxinzelelo.
UKhetho lweMathiriyeli: Ayiyiyo yonke into engama-316 engenaStainless
Ukungagqibeki kokutya yi-AISI 316L yensimbi engenasici. Kukulungelelana okulungileyo. Kodwa kwiingxenye ze-homogenizer, ngakumbi iivalvu kunye nezihlalo kwi-abrasive kakhulu okanye kwi-saline applications, kufuneka ujonge amabakala anzima, ii-stellite coatings, okanye i-ceramic epheleleyo. Ndakha ndasebenza kumgca wokuncamathisela itumata apho imbewu yayifana nokusila intlama. Izihlalo ezisemgangathweni ezingama-316 zahlala iveki. Ukutshintshela kwisitulo esijongene ne-tungsten carbide kwandisa ubomi benkonzo ukuya ngaphezulu kweenyanga ezintathu. Iindleko zaziphezulu, kodwa i-ROI ukusuka kwixesha elincitshisiweyo kunye notshintsho lwalukhulu.
Apha kulapho ubuchule bomthengisi buvavanywa khona. Ngaba banokuvelisa kwaye bathembeke ngomatshini ezi mathiriyeli ziphambili? Umzekelo, ii-alloys ezisekwe kwi-nickel njenge-Inconel ziyamangalisa kubushushu obuphezulu, iimeko zokonakala okuphezulu, kodwa zisisilo kumatshini. Basebenza nzima ngokukhawuleza. Udinga ivenkile yomatshini enezixhobo ezifanelekileyo, ukutya, kunye nezantya zokuvelisa indawo ecocekileyo, engenaxinzelelo. Inkampani enamava achaziweyo e-QSY kwii-alloys ezikhethekileyo ayidwelisi nje amagama e-buzzwords; ukubanakho ukuguqulela ngokuthe ngqo ekuveliseni ixesha elide, isicelo-specific amalungu homogenizer ezisombulula iingxaki zokwenyani zokunxiba.
Musa ukulibala malunga neegaskets kunye neengxenye 'ezithambileyo'. I-EPDM, i-Viton, i-PTFE-ukhetho apha luqhutywa yi-chemistry yemveliso, umxholo we-fat, kunye nokucoca amaqondo okushisa. Itywina leViton linokulunga kwimveliso yobisi enamafutha aphezulu kodwa inokudumba kwaye lisilele kwisicelo sokwenza utywala kusetyenziswa izicoci ezithile zeCIP. Ukugcina ingxelo eneenkcukacha zokuba yeyiphi imathiriyeli eyasetyenziswa apho, kwanobomi bayo obujongweyo, kusisiseko kodwa kulwazi lwezizwe oluxabiseke kakhulu.
Ukudityaniswa kunye neMvalelo yeSondlo
Okokugqibela, ukuba nawo onke amalungu afanelekileyo yinto enye. Ukuzifaka 'ngemvakalelo' echanekileyo yenye. Ukukrwaqula indibano yevalvu ayithethi malunga nokuyikrazula kumlinganiselo omkhulu. Imalunga nolandelelwano oluchaziweyo kunye netorque ukuqinisekisa nokuba ukulayisha ngaphandle kokuphazamisa amacandelo. Ukuntywila ngokugqithisileyo kunokutshiza amatywina, ukugqwesa izikhokelo zevalvu, kunye nokuqhekeka iiplunge ze-ceramic. Kukho impendulo ebambekayo xa idlala lokupakisha lilungelelaniswe ngokuchanekileyo-ukutsala kancinci kodwa intshukumo egudileyo. Awufundi loo nto kwincwadana yemigaqo; uyayifunda ngokuyenza engalunganga amaxesha ambalwa kwaye ubone iziphumo.
Ulawulo lwamalungu asetyenzisiweyo luqeqesho lwalo. Ayikokuba nevalve esitokhweni. Imalunga nokuba nekhithi yokutywina echanekileyo, intwasahlobo echanekileyo yevalve yokukhangela, kunye ne-O-ring ethile yezibuko lokuhlola lobushushu lalo modeli kunye nenombolo yesiriyali. I-O-ring yegeneric inokungena, kodwa ukuba i-durometer (ubunzima) yayo icinyiwe, iya kuphuma kwaye ingaphumeleli phantsi koxinzelelo lwe-pulse. Ukulungelelanisa iinxalenye ngomatshini, kungekhona nje ngohlobo, konga iiyure ngexesha lokuqhekeka.
Ke, xa ucinga ngamalungu e-homogenizer, cinga ngokwenkqubo. Yinkqubo yendalo yamacandelo anoxinzelelo oluphezulu, ukusuka kwivalve yokujonga i-inlet ukuya kwitywina lokugqibela lokukhutshwa, zonke zenziwe ngemathiriyeli ekhethelwe umlo ochasene nokunxiba, ukubola kunye nokudinwa. Ukusebenzisana nabavelisi bezobugcisa abaqonda uxinzelelo olubandakanyekayo kwinqanaba lesinyithi kunye nelomatshini, njengabo basebenza ngokuchanekileyo kunye ne-CNC ye-alloys yokusebenza, ukuguqula ukutshintshwa kweendawo ukusuka kwindleko esebenzayo ibe yinto yobuchule bobunjineli obuthembekileyo. Yiloo nto egcina uxinzelelo oluzinzileyo kunye nemveliso engaguqukiyo.
