Yiliphi izinga okufanele umoya wokusebenza wevalvu kagesi uhlangabezane nalo? Thenga idivayisi ye-valve kagesi kudingeka unake inkinga Isivinini sokushintshwa kwamandla kagesi singashintshwa, isakhiwo esihlangene, ukugcinwa okulula, kufanelekile ukulawula igesi, amanzi, umusi, zonke izinhlobo zezinto ezigqwalayo, isihlabathi, uwoyela, insimbi ewuketshezi nezinto ezinomsakazo. nezinye izinhlobo zokugeleza kwamanzi. Idivayisi ye-valve kagesi ingumshini obalulekile wokukhuthaza ukulawula uhlelo lwe-valve yesango, isilawuli esizenzakalelayo nesilawuli kude. Ukunyakaza kwayo kungalungiswa ngokuhlelwa kwe-stroke, i-torque noma usayizi we-radial thrust. Ngoba izici zokusebenza zedivayisi ye-valve kagesi kanye nesilinganiso sokusebenzisa sincike esivinini sokushintshwa kwamandla kagesi kungashintshwa, ukwakheka okuhlangene, ukugcinwa okulula, okufanelekile ukulawula igesi, amanzi, umusi, zonke izinhlobo zezinto ezonakalisayo, isihlabathi, uwoyela, insimbi ewuketshezi kanye izinto ezinemisebe nezinye izinhlobo zokugeleza koketshezi. Idivayisi ye-valve kagesi ingumshini obalulekile wokukhuthaza ukulawula uhlelo lwe-valve yesango, isilawuli esizenzakalelayo nesilawuli kude. Ukunyakaza kwayo kungalungiswa ngokuhlelwa kwe-stroke, i-torque noma usayizi we-radial thrust. Ngenxa yokuthi izici zokusebenza nezinga lokusebenzisa ledivayisi ye-valve kagesi lisohlotsheni lwe-valve, isistimu yokusebenza yedivayisi kanye nendawo ye-valve yesango epayipini noma impahla, ukukhethwa okufanele kwedivayisi ye-valve kagesi kubaluleke kakhulu ukuze kugwenywe. ukwenzeka kwesimo sokugcwala ngokweqile (isikhathi sokudlulisa sokusebenza siphezulu kunetorque yokusebenza). Ngenxa yokuthi idivayisi kagesi ku-valve kagesi iyimishini yemishini, isimo sayo somsebenzi yilo monakalo wendawo yokusebenza mkhulu kakhulu. Ngokuvamile, indawo yehhovisi lapho i-valve kagesi ikhona inamaphuzu alandelayo: 1, enomzimba womhwamuko ovuthayo, ovuthayo noma indawo yemvelo yentuthu; 2. Indawo yokuhlala emikhunjini yempi namachweba emikhumbi emisha (enokumelana nokugqwala, i-aspergillus flavus, imanzi nokubanda); 3. Izindawo ezinokudlidliza okuqinile; 4. Izindawo ezilungele izingozi zomlilo; 5, indawo ebandayo emanzi, imvelo eyomile yesimo sezulu esishisayo; 6, izinga lokushisa lempahla yamapayipi lifinyelela ku-480 ℃; 7. Ukufakwa kwangaphakathi noma uhlelo lokusebenza lwangaphandle olunezinyathelo zokuvimbela; 8, umhlangano wangaphandle wangaphandle, umoya opholile, isihlabathi, amazolo asekuseni, ukugqwala kwelanga; 9, izinga lokushisa lokusebenza lingaphansi kuka -20 ℃; 10. Kulula ukucwiliswa emanzini noma ukucwiliswa emanzini; 11. Yiba nendawo yemvelo yezinto ezikhipha imisebe (izitshalo zamandla enuzi kanye nokufakwa kokuhlola kwesici somsakazo); Ukuze i-valve kagesi ngaphansi kwendawo engenhla, isakhiwo sayo sedivayisi kagesi, izinto zokwakha kanye nezinyathelo zokuvimbela zihlukile. Ngakho-ke, idivayisi kagesi ye-valve ehambisanayo kufanele ikhethwe ngokusho kwendawo yehhovisi engenhla. Idivayisi kagesi ye-valve iwukuthuthukisa ukulawulwa kohlelo lwe-valve yesango, isilawuli esizenzakalelayo nesilawuli kude esidingekayo semishini yomshini, ukunyakaza kwayo kungalungiswa ngohlelo lokuhamba, i-torque noma usayizi we-radial thrust. Ngenxa yokuthi izici zokusebenza nezinga lokusebenzisa ledivayisi kagesi ye-valve lisehlotsheni le-valve, isistimu yokusebenza yedivayisi kanye nendawo ye-valve yesango epayipini noma impahla, ukukhethwa okufanele kwedivayisi kagesi ye-valve kubaluleke kakhulu ukugwema. izimo zokulayisha ngokweqile (i-torque yokusebenza iphakeme kunetorque yokusebenza). Ngokuvamile, isisekelo esibalulekile sokukhethwa okulungile kwamadivaysi kagesi we-valve kanje: I-torque esebenzayo: i-torque esebenzayo iyipharamitha eyisisekelo kakhulu yedivayisi kagesi ye-valve. I-torque etholakala kudivayisi kagesi kufanele ibe izikhathi ezingu-1.2 ~ 1.5 ze-torque yangempela yokusebenza ye-valve yesango. I-thrust operation yangempela: isakhiwo esiyinhloko sedivayisi kagesi ye-valve sinezinhlobo ezimbili: eyodwa ayinayo i-thrust disc, i-torque ethunyelwa ngokushesha; Enye ifakwe i-thrust disc futhi i-torque etholakalayo iguqulwa ibe yi-derived thrust ngokuvumelana ne-stem nut ku-thrust disc. Inani lokujika lokuzungezisa kwe-shaft yokufaka: inani lokuphenduka kwe-shaft yokufaka yedivayisi kagesi ye-valve lihlobene nobubanzi obuncane bevalvu, ibanga lesihlalo kanye nenani lezikulufu. Kufanele ibalwe ngokusho kwe-M = H/ZS (M inani eliphelele lokujika lokuphenduka okufanele idivayisi kagesi ihlangabezane nayo, H ubude obuhlobene bokuvulwa kwe-valve yesango, u-S yi-screw pitch yesistimu yokushayela isihlalo se-valve, futhi Z inombolo yezikulufo zesihlalo sevalvu). Indawo yesihlalo: Amavavu esango azungezayo aneziqu eziningi awakwazi ukufakwa njengamavalvu kagesi uma idivayisi kagesi ivumela indawo yokuhlala enkulu kakhulu eceliwe ukuthi ingangeni esiqwini sevalvu ehlinzekiwe. Ngakho-ke, ububanzi obujwayelekile be-shaft yokufaka engenalutho yedivayisi kagesi kufanele budlule ububanzi besiqu se-valve yenduku evulekile. Kwamanye ama-valve esango elijikelezayo kanye nama-valve esango lenduku evulekile kuma-valve amasango amaningi ajikelezayo, nakuba asikho isidingo sokukhathazeka ngenkinga yobubanzi besihlalo, indawo yokuvula isihlalo se-valve kanye nosayizi we-groove kufanele futhi kucatshangelwe ekukhethweni komhlangano, ukuze unike amandla ukusebenza okuvamile ngemva kokuhlanganisa. Isilinganiso sesivinini esitholakalayo: Uma izinga lokuvula nokuvala le-valve lishesha kakhulu, kulula ukukhiqiza into yokushaywa kwamanzi. Ngakho-ke, kufanele kusekelwe ezinhlobonhlobo ezahlukene zesicelo, khetha isivinini esifanele sokuvula nokuvala. Amadivayisi kagesi e-valve anezidingo ezikhethekile ezingakhawulela i-torque noma amandla e-radial. Idivayisi kagesi yevalvu evamile isebenzisa ukuhlangana kwetorque elinganiselwe. Uma ukucaciswa kwedivayisi kagesi kucacile, i-torque yayo yokuphatha ingase iqinisekiswe. Ngokuvamile ekusebenzeni kwesikhathi esinqunyiwe ngaphambili, injini akulula ukuyilayisha kakhulu. Kodwa uma izimo ezilandelayo zingabangela ukulayisha ngokweqile: okokuqala, amandla amanje aphansi, awakwazi ukuthola i-torque edingekayo, ukuze imoto iyeke ukujikeleza; Okwesibili, i-torque ilungiswa ngokungalungile ukuze ikhawule inhlangano, ukuze idlule i-torque emisiwe, okuholela ekubangeleni okuqhubekayo kwe-torque eningi, ukuze imoto iyeke ukujikeleza; Ezintathu isicelo ngezikhathi ezithile, idiphozi ukushisa, ngaphezu motor evunyelwe ukwanda lokushisa; Okwesine, ngenxa yezizathu ezihlukahlukene, ukwehluleka kwesifunda sokunikezwa kwamandla kwenhlangano yomkhawulo we-torque, ukuze i-torque inkulu kakhulu; Okwesihlanu, izinga lokushisa lendawo yokusetshenziswa liphezulu kakhulu, futhi ukuhlobana kunciphisa ukuqhutshwa kokushisa kwemoto. Esikhathini esidlule, indlela yokuvikela imoto ukusetshenziswa kwe-circuit breaker, phezu kwe-valve ye-solenoid yamanje, ukudlulisa ukushisa, isilawuli sokushisa, kodwa lezi zindlela zinezinzuzo zazo. Ayikho indlela ethembekile yokulungisa imishini eshintshashintshayo efana nemishini kagesi. Ngakho-ke, ukuhlelwa okuhlukahlukene kufanele kuthathwe, ikakhulukazi kukhona okubili okuyinhloko: eyodwa ukwahlulela ukulungiswa kwe-motor input current; Okwesibili ukwahlulela isimo esivuthayo semoto ngokwayo. Zombili izindlela, kungakhathaliseki ukuthi ikilasi izocabangela conductivity ezishisayo injini isikhathi esinikeziwe umthamo. Ngokuvamile, iyiphi indlela eyisisekelo yokugcinwa kwe-overload: ukuvikelwa kokulayisha ngokweqile kokusebenza okuqhubekayo noma ukuqala ukusebenza kwemoto, ukukhethwa kwesilawuli sokushisa; Ukuze ulondoloze ukuphenduka kwezimoto, khetha ukudluliselwa kokushisa; Ngengozi yokuphepha yesiphambeko sesekethe emfushane, khetha i-circuit breaker noma ngaphezulu kwevalvu ye-solenoid yamanje.
