1. Yintoni iWater Hammer? Ithetha ukuthini iWater Hammer kwi-Industrial Solid-Liquid Filtration?
I-Water hammer, eyaziwa ngokuba yi-hydraulic shock, kukunyuka koxinzelelo okwenzeka xa isantya solwelo sitshintsha ngequbuliso [1]. Oku kunokwenzeka ngeendlela ezimbini eziqhelekileyo:
- Ukuyeka ukuhamba kwamanzi ngequbuliso:Xa ivalvu ivala ngokukhawuleza, ulwelo oluhambayo luyanyanzeleka ukuba luyeke, kwaye amandla alo e-kinetic aguqulwa abe yi-high-pressure wave ehamba ibuya ngepayipi [2]. Olu luhlobo oluqhelekileyo lwe-water hammer.
- Ukukhawulezisa ukuhamba kwamanzi ngequbuliso:Xa ivalvu ivuleka ngokukhawuleza, ulwelo olungashukumiyo okanye oluhamba kancinci lukhawuleza ngequbuliso. Ngenxa yokuba ulwelo lune-inertia kwaye uxinzelelo oluphezulu sele luphezulu, olu khawulezileyo lunokubangela uxinzelelo olunamandla, ingakumbi kwimigca yokukhupha okanye yokukhupha amanzi [4].
Kwi-industrial solid-liquid filtration, i-water hammer inokwenzeka kakhulu ngexeshainqanaba lokukhupha okanye lokukhupha umqoloXa ivalvu yokukhupha amanzi okanye ivalvu yokubuyisela amanzi emva ivuleka ngequbuliso, ulwelo oluxinzelelweyo lungena kumgca wokukhupha amanzi ngokukhawuleza. Okukhona ivalvu ivuleka ngokukhawuleza, kokukhona ukugeleza kwamanzi okuqala kuyanda kwaye kubekho ukubetheka koxinzelelo. Kwiifilitha ze-multi-element, esi siphumo sibi kakhulu kuba ukugeleza kwamanzi kunokugxininiswa kumasebe ambalwa okanye kwelinye.
Ke ngoko, kwiifilitha ezizihlanzayo umva, ihamile yamanzi ayibangelwa kukuvala ivalvu, kodwa kukuvalwa kwevalvu.ivula ngokukhawuleza ivalvu yokukhupha amanziukukhupha umthamo omkhulu wolwelo oluxinzelelweyo. Ngokutsho kweHydraulic Institute [1], Engineering ToolBox [2], kunye neCrane Technical Paper No. 410 [4], zombini ukuyeka ukuhamba ngequbuliso kunye nokukhawulezisa ukuhamba ngequbuliso kunokubangela ukunyuka koxinzelelo okonakalisayo kwiinkqubo zemibhobho yemizi-mveliso.
2. Zithini iingozi zeWater Hammer? Zithini iingozi kwiinkqubo zokuhluza i-industrial?
Ihamile yamanzi ayisiyongxaki nje yengxolo. Inokubangela umonakalo omkhulu kwiinkqubo zokucoca zoshishino kunye nezixhobo ezingqongileyo [3].
Iingozi eziqhelekileyo ziquka:
- Umonakalo wepayipi kunye nokufakelwa
Ukunyuka koxinzelelo ngequbuliso kunokuphazamisa imibhobho, kuqhekeze iiflange, okanye kukhulule amalungu. Kwiinkqubo zokucoca, imibhobho yokukhupha amanzi isengozini kakhulu kuba idla ngokuphatha ulwelo olunesantya esiphezulu okanye ulwelo olungcolileyo [4].
- Ukusilela kwevalvu
Iivalvu ezivula ngokukhawuleza okanye ezivala ngokukhawuleza, ezifana neevalvu zebhola eziphuma kwi-pneumatic okanye iivalvu ze-solenoid, zinokonakala ngenxa yesando samanzi esiphindaphindwayo. Izihlalo, izitywini, kunye nee-actuator zinokuguga ngokukhawuleza [2].
- Ukungcangcazela kunye noxinzelelo loomatshini
Ukungcangcazela okunamandla kunokukhulula iibholithi, konakalisa uqhagamshelo lwezixhobo, kwaye kunokubangela ukudinwa kwesakhiwo ngokuhamba kwexesha [4].
- Umonakalo wezinto zepompo kunye nesihluzi
Ukunyuka koxinzelelo kunokudlulisela umva kwaye kuchaphazele indawo yesihluzo, izinto zesihluzo, kunye neempompo ezisezantsi. Oku kuyingozi ngakumbi kwii-multi-cartridge okanye ii-multi-tube filters apho ukuhamba kwamanzi kuxineneyo [1].
Kwi-industrial solid-liquid filtration, imeko eqhelekileyo ye-water hammer yenzeka ngexeshaukuhlanjwa umva ngokuzenzekelayoXa kuphela into enye okanye ezimbalwa zesihluzo zihlanjwa umva ngexesha, ukuhamba kokukhupha kuyaxinaniswa. Ukuba ivalvu yokukhupha amanzi ivuleka ngokukhawuleza, ukuphuma kolwelo ngequbuliso kudala amaza oxinzelelo olunamandla. Iinjineli kwiVITHY Filtration ziye zakubona oku kwezinye izihluzo zesiqhelo zokukhupha amanzi emva: xa ivalvu yokukhupha amanzi ivuleka, ukuhamba kwamanzi kuba kukhulu, uxinzelelo luphezulu, kwaye ukungcangcazela kunamandla ngokwaneleyo ukonakalisa umbhobho wokukhupha amanzi ngokuhamba kwexesha.
Ngokwahlukileyo koko, isihluzo sokuzicoca esizicoca kakuhle asinakwenzeka ukuba sibangele ihamile yamanzi. Kwisihluzo sokuzicoca, indlela yokukhupha amanzi inokumelana okuncinci, kwaye ukuhamba kwamanzi kuncinci. Ngenxa yoko, utshintsho loxinzelelo luhamba kancinci, kwaye inqanaba lokungcangcazela liphantsi kakhulu. Oku kuqinisekiswe ngamava asentsimini: abathengi abasebenzisa iVITHY Filtration'sIsihluzi se-VAS sokuzicocaandizange ndibike ngeengxaki zesando samanzi.
3. Ungakuphepha njani ukuHammer kwamanzi kwimisebenzi yokucoca yemihla ngemihla kwimizi-mveliso?
Kukho iindlela ezininzi ezisebenzayo zokunciphisa okanye ukuphepha ihamile yamanzi kwiinkqubo zokucoca. Uninzi lwazo zibiza kancinci kwaye zingasetyenziswa kwiindawo ezikhoyo [4].
(1) Yehlisa isantya sokusebenza kwevalvu
Sebenzisa ii-actuators zomoya okanye zombane ezine-speed control. Ukongeza i-valve elawula umthombo womoya kwi-solenoid valve kunokwenza i-valve ivuleke kwaye ivale kancinci, nto leyo enciphisa ukunyuka koxinzelelo. Nangona kunjalo, le ndlela inokunyusa ukusetyenziswa kwamanzi ngexesha lomjikelo we-back-flush kuba i-valve ihlala ivuliwe ixesha elide [5].
(2) Qinisekisa imibhobho yokukhupha amanzi
Imibhobho yokukhupha amanzi kufuneka ixhaswe ngokuqinileyo kwaye iqiniswe ukuze ifunxe ukungcangcazela. Imibhobho engakhuselekanga inokuba namandla okungcangcazela xa kutshintshwe uxinzelelo ngesiquphe [4].
(3) Faka ivalvu yokuthomalalisa ngesandla
Ivalvu elula efakwe ngesandla kumgca wokukhupha amanzi ingavalwa kancinci (umz., ukuvuleka kwe-50%) ukuthintela ukuhamba kokukhupha amanzi kunye nokunciphisa uxinzelelo. Ngokunciphisa isantya esiphezulu sokuhamba kwamanzi, ivalvu yokuthomalalisa amanzi ithintela ulwelo ukuba lukhawuleze ngokukhawuleza, nokuba ivalvu yokukhupha amanzi ivuleka ngokukhawuleza. Esi sisisombululo esisebenzayo kwizihluzi ezikhoyo, kodwa kufuneka sihlolwe rhoqo ukuqinisekisa ukuba indawo yevalvu ayitshintshanga [5].
(4) Sebenzisa ukhetho olufanelekileyo lwevalvu
Khetha iivalvu ezinexesha elifanelekileyo lokuvala lenkqubo. Ziphephe iivalvu ezinkulu ezivula okanye ezivala ngokukhawuleza kunokuba kuyimfuneko. Kwiinkqubo ezizenzekelayo, khetha ii-actuators ezinesantya esihlengahlengiswayo [1].

Isihluzi sokufunxa umva se-VSRF esizenzekelayo
Uthotho lwe-VSRF luyilelwe usetyenziso olufuna ukuhlanjwa ngokuzenzekelayo kwezinto zesihluzi ngasinye. Kwisihluzi esiqhelekileyo sokuhlanjwa ngasemva, xa into enye okanye ezimbalwa zihlanjwa ngasemva ngexesha, ukuhamba kwamanzi kuyaxinaniswa kwaye ukuvuleka kwevalvu yokukhupha amanzi kunokubangela ukunyuka koxinzelelo olukhulu. I-VITHY Filtration ijongene nale ngxaki ngeendlela ezimbini:
(1) Ulawulo lwesantya somoya kwiivalvu zokukhupha amanzi
Ivalvu yokulawula umthombo womoya ifakwe kwivalvu yesolenoid. Ivalvu inganciphisa isantya sokuvula nokuvala kwevalvu. Oku kunciphisa kakhulu ukunyuka koxinzelelo kunye nokungcangcazela ngexesha lokuhlanjwa umva. Sicebisa ukuba uhlolwe rhoqo ivalvu yokulawula ukuqinisekisa ukuba ihlala iqinile ngokufanelekileyo. Ekuhambeni kwexesha, ukungcangcazela kunokubangela ukuba i-nut ikhululeke, nto leyo enokunciphisa isiphumo sokudambisa kwaye ivumele ihamile yamanzi ukuba ibuye.
(2) Iingcebiso zombhobho wokukhupha amanzi
Ukuba ukucothisa ivalvu akuthandwa kuba kwandisa ukusetyenziswa kwamanzi aphuma emqolo, sicebisa amanyathelo amabini ongezelelweyo:
- Lungisa kwaye uxhase imibhobho yokukhupha amanzi ngokuqinileyo ukuze ufunxe ukungcangcazela.
- Faka ivalvu esetyenziswa ngesandla ezantsi komsinga uze uyigcine ivulekile kancinci kuphela xa uhlambulula umva. Oku kunciphisa izinga eliphezulu lokuphuma kwamanzi kwaye kuthintela ulwelo ukuba lukhawuleze ngokukhawuleza, ngaphandle kokunyusa ukusetyenziswa kwamanzi ngokupheleleyo.
