Umthelela wesando samanzi sevalvu Yethula isizathu nesixazululo sokugcwala ngokweqile kwe-valve kagesi esebenza ngogesi!

Umthelela wesando samanzi sevalvu Yethula isizathu nesixazululo sokugcwala ngokweqile kwe-valve kagesi esebenza ngogesi! "I-Water Hammer Effect" ibhekisela kulokho lapho i-valve evulekile ivalwa ngokuzumayo, ngenxa ye-inertia yokucindezela Ukugeleza kwamanzi, i-Water shock wave izokhiqizwa futhi umonakalo uzokhiqizwa. Lona "umphumela wesando samanzi" ku-hydrology, owaziwa nangokuthi isando samanzi esihle. Ngokuphambene nalokho, ngemva kokuba i-valve evaliwe ivuliwe ngokuzumayo, izophinde ikhiqize isando samanzi, esibizwa ngokuthi isando samanzi esibi, futhi kukhona ikhefu elithile Umphumela Wesando Samanzi Kubhekisela lapho i-valve evulekile ivaliwe ngokuzumayo, ngenxa ye-inertia yokucindezela. ukugeleza kwamanzi, igagasi lokushaqeka lokugeleza kwamanzi lizokwenziwa, futhi umphumela wokubhubhisa uzokhiqizwa. Lona "umphumela wesando samanzi" ku-hydrology, okuyisando samanzi esihle. Ngokuphambene nalokho, ngemva kokuba i-valve evaliwe ivuliwe ngokuzumayo, izophinde ikhiqize isando samanzi, esibizwa ngokuthi isando samanzi esibi, esinamandla athile okubhubhisa, kodwa hhayi amakhulu njengangaphambili. Ngokuvamile, isici sokuvala sidonselwa kungazelelwe esihlalweni njengoba i-valve isondela ekuvaleni, eyaziwa ngokuthi i-solution cylinder latching effect. I-cylinder latching effect ibangelwa i-actuator ye-low-thrust engenakho ukusunduza okwanele ukuze uhlale eduze nesihlalo, okuholela ekuvaleni kungazelelwe kwepompo noma i-valve, okuholela kumphumela wesando samanzi. Kuma-valve okulawula, kwezinye izimo, izici zokugeleza okuvula ngokushesha zingaholela kumphumela wesando samanzi. Nakuba isando samanzi senza umsindo omkhulu, umonakalo wangempela ubangelwa ukwehluleka komshini. Ngenxa yoshintsho olusheshayo olusuka kumandla e-kinetic ukuya ekucindezelweni komugqa omile, isando samanzi singabhodloza umugqa noma sonakalise ukusekela kwepayipi futhi kulimaze ukuhlangana komugqa. Kuma-valve, isando samanzi singabangela ukudlidliza okukhulu nge-spool, okungabangela ukwehluleka kwe-spool, i-gasket noma ukupakisha. Ngama-valve, ukuvikela kwisando samanzi ukuvimbela noma yikuphi ukuguquka kwengcindezi engazelelwe ohlelweni. Lokhu kuhlanganisa ukunciphisa ukuvala kwe-valve ngokwayo noma ukuhlinzeka ngezinga elikhulu lokushuba nokuqina njengoba isici sokuvala sisondela esihlalweni. Ukuze uvimbele ukushintshashintsha kwengcindezi, i-valve kufanele ivalwe ngesivinini esifanayo. Kwezinye izimo, uma usebenzisa isici esivuleka ngokushesha, ungacela ukuthi isici esilingana nephesenti sishintshwe. Kumavalvu okulawula okufanele anyakaziswe lapho eseduze nesihlalo, ama-actuator ane-thrust ephumayo eyanele kufanele asetshenziswe, njengama-piston pneumatic actuators noma ama-hydraulic actuators, noma amanotshi akhethekile kumkhono we-stroke wama-opharetha azungezayo azonciphisa noma avimbele ukukhiywa kwamasilinda. Olunye uhlobo lokuvikela igagasi ohlelweni lwamapayipi lunganciphisa izando zamanzi. Lokhu kungenziwa ngokusebenzisa i-valve yokukhulula ingcindezi noma umgqomo we-buffer. Ngaphezu kwalokho, igesi ingajovwa ohlelweni, okunciphisa ukuminyana koketshezi futhi inikeze ukucindezelwa okuthile ukuze kusingathwe noma yikuphi ukuguquguquka okungazelelwe. I-Valve actuator kagesi igcwele izizathu nezixazululo! Izizathu zokulayisha ngokweqile kwe-valve kagesi we-actuator: okokuqala, ukunikezwa kwamandla kuphansi, hhayi i-torque edingekayo, ukuze injini iyeke ukujikeleza; Okwesibili, akulungile ukulungisa indlela yomkhawulo we-torque, ukuze ibe mkhulu kune-torque emisiwe, okuholela ku-torque eqhubekayo eqhubekayo, ukuze injini iyeke ukujikeleza; Okuthathu ukusetshenziswa ngezikhathi ezithile, ukonga ukushisa, ngaphezu kwemoto evunyelwe Izizathu zokugcwala ngokweqile kwe-valve actuator kagesi: Okokuqala, ukunikezwa kwamandla kuphansi, hhayi i-torque edingekayo, ukuze injini iyeke ukujikeleza; Okwesibili, akulungile ukulungisa indlela yomkhawulo we-torque, ukuze ibe mkhulu kune-torque emisiwe, okuholela ku-torque eqhubekayo eqhubekayo, ukuze injini iyeke ukujikeleza; Okuthathu ukusetshenziswa kwezikhawu, ukonga ukushisa, ngaphezu kokukhuphuka kwezinga lokushisa okuvunyelwe kwemoto; Okwesine, ngesizathu esithile itorque ekhawulela ukwehluleka kwesekethe, ukuze itorque ibe nkulu kakhulu; Okwesihlanu, ukusetshenziswa kwezinga lokushisa kwe-ambient kuphezulu kakhulu, uma kuqhathaniswa nokwehla kwamandla okushisa kwemoto. Esikhathini esidlule, ama-fuse, ama-overcurrent relays, ama-thermal relays kanye nama-thermostats asetshenziselwa ukuvikela ama-motor, kodwa lezi zindlela zinezinzuzo kanye nokubi. Ayikho indlela ephephile nethembekile yokuvikela izinto zikagesi ezinomthwalo oguquguqukayo. Ngakho-ke, kuyadingeka ukuthatha inhlanganisela ehlukahlukene, efingqiwe ngezindlela ezimbili: eyodwa ukwahlulela ukwanda noma ukuncipha kwamandla okufakwayo kwemoto; Okwesibili ukwahlulela injini ngokwayo. Lezi zindlela ezimbili, kungakhathaliseki ukuthi iyiphi indlela yokucabangela umthamo wokushisa wemoto onikezwe umkhawulo wesikhathi. Ngokuvamile, ukuvikelwa okuyisisekelo ekulayisheni ngokweqile yilezi: 1. Ukusebenza okuqhubekayo kwemoto noma ukusebenza kwendawo yokuvikela ukulayisha ngokweqile, usebenzisa i-thermostat; 2. I-thermal relay isetshenziselwa ukuvikela ukuvinjwa kwezimoto; 3. Ngengozi yesekethe emfushane, sebenzisa i-fuse noma i-overcurrent relay. I-Valve electric actuator iyisisetshenziswa esibalulekile sokulawula uhlelo lwe-valve, isilawuli esizenzakalelayo nesilawuli kude. Inqubo yayo yokunyakaza ingalawulwa nge-stroke, i-torque noma i-axial thrust. Ukukhetha okulungile kwedivayisi kagesi ye-valve kubaluleke kakhulu ukuvimbela into egcwala kakhulu (i-torque esebenzayo iphakeme kune-torque yokulawula).
