Kwivenkile yokulungisa i-hydraulic yamva nje, ndibuzwe ukuba ndicinga ntoni malunga nevalve yokubeka yodwa kumgca wokufunxa wempompo kwaye ingaba kuyimfuneko na ukusebenzisa ivalve yebhola ebiza kakhulu endaweni yevalve yebhabhathane enexabiso eliphantsi. Ingcambu yale ngxaki ixhomekeke kwimiphumo emibi ye-turbulence kumgca wokufunxa impompo. Ingxabano yokusebenzisa ivalve yebhola njengevalve yokwahlula kumbhobho wokungena kukuba xa ivuliwe, ibhore epheleleyo yevalve ivumela ukuhamba kweoli. Ngoko ke, ukuba ufaka i-valve yebhola ye-2-intshi kumgca wokuthatha i-intshi ye-2, xa i-valve ivula, iya kuba ngathi ayikho nhlobo (ubuncinci ukusuka kwindawo yokujonga ioli).
Kwelinye icala, iivalve zebhabhathane azigcwali ngokupheleleyo. Naxa ivulwe ngokupheleleyo, ibhabhathane lihlala lisemngxunyeni kwaye libonisa izithintelo ezithile zeemilo ezingaqhelekanga. Oku kubangela isiphithiphithi, esibangela ukuba umoya odibeneyo uphume kwisisombululo kumbhobho wokungenisa. Ukuba oku kuyenzeka, la maqamza aya kugqabhuka xa uxinzelelo lusetyenziswa kwindawo yokupompoza. Ngamanye amazwi, iivalve zebhabhathane zinokubangela i-cavitation.
Ngoko ke yeyiphi eyona ilungileyo: ivalve yebhola okanye ivalve yebhabhathane? Ewe, njengeengxaki ezininzi kwiinkqubo ze-hydraulic, kuxhomekeke. Kwihlabathi eligqibeleleyo, ndingahlala ndikhetha iivalve zebhola ngaphambi kweevalve zebhabhathane. Kwimibhobho yokungena ukuya kwi-intshi ezi-3 ububanzi, akukho phantse ilahleko yeendleko ukwenza oko.
Nangona kunjalo, xa ufaka i-intshi ezi-4, i-intshi engu-6, kunye ne-intshi eyi-8 ububanzi, iivalvu zebhola zibiza kakhulu xa zithelekiswa neevalve zebhabhathane. Bakwathatha indawo eninzi ngakumbi, ngakumbi kubude obupheleleyo. Ngoko ke, umzekelo, kwizicelo eziphathwayo, kungekhona kuphela iindleko ze-valve yebhola enkulu enokuthi ibe phezulu kakhulu, kodwa kunokungabi nendawo eyaneleyo phakathi kwetanki yokuphuma kunye ne-inlet yempompo yokuyifaka.
Kukho inketho yesithathu. Abantu abaninzi bakholelwa ngempazamo ukuba i-valve yokuhlukanisa i-valve yokuthatha ibalulekile, kodwa enyanisweni akunjalo, kodwa kukho iimeko ezimbalwa kuphela.
Umbuzo wokuqala ovelayo ekuphenduleni le ngxaki yindlela yokubuyisela umpompo ukuba akukho valve yokuhlukanisa kumgca wokuthatha. Kukho iimpendulo ezimbini kule nto. Okokuqala, ukuba ipompo ihluleka ngentlekele kwaye wenza into "elungileyo", kufuneka usebenzise inqwelo yokucoca ukutsala ioli kwi-tank kwaye uyibeke kwibhakethi ecocekileyo okanye enye isitya esifanelekileyo. Itanki yamafutha kufuneka icocwe ngokucokisekileyo, impompo itshintshwe, kwaye inqwelo yokucoca kufuneka isetyenziswe ukumpompa i-oyile (kucingelwa ukuba isekhona) ibuyele etankini.
Inkcaso jikelele koku kukuba: oh, asinaxesha lakwenza oku!q okanye pAsina-10, 20, okanye amagubu amaninzi acocekileyo.q Kwabo bangafuni ukuwenza kakuhle umsebenzi, isisombululo esinye kukutywina zonke iindawo ezinokungena kwi-tank top space, kwaye uqhagamshele isicoci se-industrial vacuum kwindawo evuzayo yesiphefumlo setanki. Vula isicoci sempompo xa ubuyisela impompo, kwaye uphinde usebenze xa i-debris evela kukusilela kwempompo yokugqibela kubangele ukuba impompo yokutshintshwa ingaphumeleli.
Kakade ke, zikho iimeko ezikhethekileyo. Umzekelo, ukuba kukho iimpompo ezininzi ezifunxayo kwitanki enye, okanye ukumpompa iilitha ezingama-3,000 zeoyile kwitanki akunakwenzeka. Ngamanye amaxesha i-valve yokuhlukanisa ibhobho yokungenisa iyimfuneko. Ukuba kunjalo, kubulumko ukuqinisekisa ukuba banokutshintshana ngokusondeleyo ukukhusela impompo ekuqaliseni xa i-valve ivaliwe.
Ukuba kuyenzeka, indlela endiyikhethayo kukufaka ivalve yebhola okanye ivalve yebhabhathane. Ukuba kufuneka ube nayo, ukuba ixabiso okanye indawo ayiyongxaki, sebenzisa ivalve yebhola. Nangona kunjalo, ukuba kukho ingxaki nayiphi na kubo, i-valve ye-butterfly iyona kuphela inketho.
Kwiinkqubo ezininzi, iivalve zebhabhathane zisetyenziswa njengeevalve zokuzihlukanisa zempompo. I-excavators enkulu ye-hydraulic ngumzekelo oqhelekileyo. Zineempompo ezininzi zokufunxa kwitanki enkulu ngombhobho omkhulu wokungena odayamitha, kwaye akukho ndawo ingako-zonke iinxalenye azibandakanyi eyona ndlela ikhethwa kakhulu (akukho valve okanye ivelufa yebhola).
Andikhumbuli ndibona ipompo kwi-excavator enkulu ye-hydraulic ngaphandle komonakalo othile we-cavitation, onokuthi uthathwe njengento eqhelekileyo kwesi sicelo. Ngaba lo monakalo we-cavitation ngenxa yesiphithiphithi esibangelwa yi-valve butterfly valve? Ewe iyakwazi, kodwa ezinye izinto ezininzi zinokuyibangela. Ekuphela kwendlela eqinisekileyo kukuthelekisa iimpompo ezimbini ezisebenza phantsi kweemeko ezifanayo-enye inevalve yebhabhathane kwaye enye ingenayo ivalve yebhabhathane.
