Esitolo sakamuva sokulungisa ama-hydraulic, ngibuzwe ukuthi ngicabangani ngevalve yokuhlukanisa emgqeni wokudonsa wepompo nokuthi kuyadingeka yini ukusebenzisa i-valve yebhola ebiza kakhulu esikhundleni sevalve uvemvane ngokuvamile eshibhile. Umsuka wale nkinga usemiphumeleni emibi yesiphithiphithi emgqeni wokumunca iphampu. I-agumenti yokusebenzisa i-valve yebhola njenge-valve yokuhlukanisa ipayipi yokungena iwukuthi lapho ivuliwe, i-bore egcwele ye-valve ivumela uwoyela ukuthi ugeleze. Ngakho-ke, uma ufaka i-valve yebhola engu-2-intshi emgqeni wokungena we-2-intshi, lapho i-valve ivula, kuyoba sengathi ayikho nhlobo (okungenani kusukela endaweni yokubuka amafutha).
Ngakolunye uhlangothi, ama-butterfly valves awagcwele. Ngisho nalapho ivuleke ngokugcwele, uvemvane luhlala emgodini futhi lubonisa imingcele eyingxenye yesimo esingajwayelekile. Lokhu kubangela isiphithiphithi, okubangela ukuba umoya oncibilikisiwe uphume esixazululweni sepayipi elingenisayo. Uma lokhu kwenzeka, lawa mabhamuza azoqhuma lapho ukucindezela kufakwa endaweni yepompo. Ngamanye amazwi, ama-butterfly valves angabangela i-cavitation.
Ngakho yikuphi okungcono kakhulu: i-valve yebhola noma i-butterfly valve? Yebo, njengezinkinga eziningi ezinhlelweni zamanzi, kuya ngokuya. Ezweni eliphelele, ngihlale ngikhetha amavalvu ebhola ngaphambi kwamavalve ovemvane. Kumapayipi okungenisa afinyelela kumayintshi angu-3 ububanzi, cishe akukho ukulahlekelwa kwezindleko ukwenza kanjalo.
Kodwa-ke, uma ufaka ama-intshi angu-4, ama-intshi angu-6, nobubanzi obuyi-intshi engu-8, ama-valve ebhola abiza kakhulu uma kuqhathaniswa namavalve ovemvane. Ziphinde zithathe indawo eyengeziwe, ikakhulukazi ngobude bayo yonke. Ngakho-ke, isibonelo, kuzinhlelo zokusebenza zeselula, hhayi kuphela izindleko ze-valve yebhola ye-caliber enkulu zingase zibe phezulu kakhulu, kodwa kungase kungabi khona isikhala esanele phakathi kwe-tank outlet kanye ne-pump inlet ukuze uyifake.
Kukhona inketho yesithathu. Abantu abaningi bakholelwa ngephutha ukuthi i-valve yokuhlukanisa ipayipi yokungenisa ibalulekile, kodwa empeleni akunjalo, kodwa kukhona okuhlukile kuphela.
Umbuzo wokuqala ovelayo ekuphenduleni le nkinga yindlela yokushintsha iphampu uma kungekho valve yokuhlukanisa emgqeni wokungena. Kunezimpendulo ezimbili kulokhu. Okokuqala, uma iphampu ihluleka ngendlela eyinhlekelele futhi wenza into “elungile,” kufanele usebenzise inqola yokuhlunga ukuze ukhiphe amafutha ethangini bese uwafaka ebhakedeni elihlanzekile noma kwesinye isitsha esifanelekile. Ithangi likaphethiloli kufanele lihlanzwe kahle, iphampu kufanele ishintshwe, futhi inqola yokuhlunga kufanele isetshenziselwe ukumpompa uwoyela (kucatshangwa ukuthi usekhona) ubuyisele ethangini.
Ukuphikiswa okujwayelekile kulokhu ukuthi: pOh, asinaso isikhathi sokwenza lokhu!q noma pAsinazo izigubhu ezihlanzekile eziwu-10, 20, noma eziningi.q Kulabo abangafuni ukwenza umsebenzi wenziwe ngendlela efanele, isisombululo esisodwa sithi Vala zonke izigubhu ezihlanzekile. izingxenye ezingenekayo esikhaleni esiphezulu sethangi, bese uxhuma isicoci se-vacuum yemboni engxenyeni ekwaziyo ukungena yesiphefumula sethangi. Vula isicoci se-vacuum lapho ushintsha iphampu, bese uphinda umsebenzi lapho imfucumfucu evela ekuhlulekeni kokugcina kwephampu kubangele ukuthi iphampu yokushintsha ihluleke.
Yiqiniso, kukhona okuhlukile. Isibonelo, uma kukhona amaphampu amaningi angena ethangini elilodwa, noma ukumpompa amalitha angu-3,000 kawoyela ethangini akwenzeki. Ngezinye izikhathi i-valve yokuhlukanisa ipayipi iyadingeka. Uma kunjalo, kuwukuhlakanipha ukuqinisekisa ukuthi banamaswishi e-proximity ukuvimbela ipompo ukuthi iqale lapho i-valve ivaliwe.
Uma kungenzeka, indlela engiyikhethayo ukufaka i-valve yebhola noma i-butterfly valve. Uma kufanele ube nayo, uma izindleko noma isikhala kungeyona inkinga, sebenzisa i-valve yebhola. Kodwa-ke, uma kunenkinga nganoma iyiphi yazo, i-valve ye-butterfly iyona kuphela inketho.
Ezinhlelweni eziningi, ama-valve ovemvane asetshenziswa njengama-valve okuhlukanisa ama-pump inlet. Ama-excavators amakhulu ama-hydraulic ayisibonelo esivamile. Anamaphampu amaningi okumunca ethangini elikhulu ngepayipi elikhulu lokudonsa eliwububanzi, futhi asikho isikhala esiningi-zonke izingxenye aziyifaki inketho ekhethwa kakhulu (ayikho i-valve noma i-valve yebhola).
Angikhumbuli ngike ngabona iphampu ku-excavator enkulu ye-hydraulic ngaphandle kokulimala okungenani kwe-cavitation, okungabhekwa njengokugqoka okuvamile kulolu hlelo lokusebenza. Ingabe lo monakalo we-cavitation ngenxa yesiphithiphithi esibangelwa i-valve butterfly? Yebo kungenzeka, kodwa ezinye izinto eziningi nazo zingayibangela. Okuwukuphela kwendlela eqinisekile ukuqhathanisa amaphampu amabili asebenza ngaphansi kwezimo ezifanayo-enye ine-valve uvemvane kanti enye ingenayo i-valve uvemvane.
UBrendan Casey unesipiliyoni seminyaka engaphezu kwengama-20 ekulungisweni, ekulungisweni nasekulungisweni kabusha kwemishini ephathwayo neyezimboni. Ulwazi olwengeziwe mayelana nokunciphisa izindleko zokusebenza kanye nokwenyuka...
