Izinkinga Ze-Valve Ezivamile - I-High Pressure Drop ichaza ukufakwa nokulungiswa kwamaphampu we-slag nomfutho ophezulu
Ngenxa yomehluko PHAKATHI OKUPHEZULU KANYE NECINDEZELO eliya phansi komfula, UKUGUBHA ngevalvu KUBIZWA OKUTHI PRESSURE DROP Ngenxa yomehluko phakathi kwengcindezi ekhuphuka nomfula, ukugeleza ku-valve kubizwa ngokuthi i-press drop drop OP, noma umfutho ohlukile. Uma Usayizi Wolayini UNGENA OKUFANAYO KANYE NOKWENZIWA KWEVIVESI FUTHI UKUXHUMANA INGQIZI, IVALI KUFANELE ILAHLEKELWE YI-FRICTIONAL UKUZE YEHLISE IMICINDEZANE YE-FLUID UKUZE IKHIQILISE UKUgeleza. Ingxenye yokulahlekelwa kwe-valve friction ibangelwa ukuhlikihlwa koketshezi nodonga lwevalvu. Nokho, lokhu kungqubuzana kuncane futhi akukwazi ukukhiqiza ukwehla kwengcindezi eyanele kuketshezi olufanele. Indlela ephumelela kakhudlwana yokukhiqiza ukulahlekelwa kwengcindezi enkulu ku-valve iwukudonsa emzimbeni we-valve. Ngenxa yokuthi AMAVAVAVA amaningi AKHELWE ukuvumela ingxenye yevalvu ukuthi IBE YINCANE KUNOMUGQA, ingahlinzeka kalula nge-THROttLING isendlalelo se-FLUID. NGENXA YOMTHETHO WOKULONDOLOZA, NJENGOBA UFLUIDI USONDELA KUMVAVAVU, isivinini sawo siyenyuka ukuze WONKE UFLUID UDLALE KUVALIVU.
Ngokuphambene nalokho, ukwehla kwengcindezi ehambisanayo kwenzeka (Umfanekiso 9.1). Ubudlelwano obuphambene phakathi kwengcindezi nesivinini kuvezwa ifomula kaBernoulli kanje:
Isivinini esiphezulu kanye nokucindezela okuphansi kwenzeka ezansi nomfula wokuminyanisa kwentamo, okubizwa ngokuthi i-constriction section. Umfanekiso 9.2 UKHOMBISA UKUTHI INGXENYE YEZINKONTRAKILE AYIZIZISHAYIZI NGOKWASO, KODWA IKUDLA EKUDLA NGAPHANSI KOKUSHIYA OKUHLUKA NGOKUCINDEZELEKA OKUHLANGANILE. Uma isivinini sesigaba senkontileka siyisivinini esiphezulu, indawo yokugeleza yesendlalelo sezinto incane. Ngemuva kwesigaba sokufinyela, ukugeleza kuncipha futhi ingcindezi ikhuphuke futhi, kodwa ayifinyeleli inani langempela lokucindezela phezulu komfula. Umehluko PHAKATHI KOmfutho we-UPSTREAM kanye nokucindezela kwe-DOWNSTREAM UBANGWA ukulahlekelwa ukungqubuzana NJENGOBA ukuhanjiswa kwempahla kugeleza kuvalvu futhi kubizwa ngokuthi PERMANENT pressure DROP. Umehluko wengcindezi phakathi kwengcindezi esigabeni se-contractile kanye nengcindezi eya phansi komfula ubizwa ngokuthi ukubuyiswa kwengcindezi. Umdwebo olula wokwehla kwengcindezi unomphela kanye nokululama kwengcindezi kuboniswe kuMfanekiso 9.3. Ukuvalwa okuphumelelayo kwamaphampu we-slag anengcindezi ephezulu kanye nama-valve kuncike esimweni sonke sengxenye ngayinye. Ukunakekelwa okukhethekile kufanele kukhokhwe esiqinisekweni sokuthi okokusebenza okudinga ukushintshwa kwempande yepani kuye kwahlukaniswa ngokuphumelelayo ngokuhambisana nesayithi kanye nesistimu ngaphambi kokufakwa kwempande ye-pan. Okulandelayo kusetshenziselwa ukuqondisa abasebenzi bokulungisa, onjiniyela, nabahlanganisi ukuze bafake kahle futhi balungise impande ye-pan.
Ukuvalwa okuphumelelayo kwepompo ye-slag yokucindezela okuphezulu kanye ne-valve kuncike esimweni sonke sezingxenye zomuntu ngamunye. Ukunakekela okukhethekile kufanele kukhokhwe esiqinisekweni sokuthi okokusebenza okudinga ukushintshwa kwempande yepani kuye kwahlukaniswa ngokuphumelelayo ngokuhambisana nesayithi kanye nesistimu ngaphambi kokufakwa kwempande yepani. Okulandelayo kusetshenziselwa ukuqondisa abasebenzi bokulungisa, onjiniyela, nabahlanganisi ukuze bafake kahle futhi balungise impande ye-pan.
1. Amathuluzi akhethekile, iphampu kawoyela we-slag enomfutho ophezulu kanye nomshini wokubopha kufanele kusetshenziselwe ukuqinisa nati lendlala lapho impande endala yepani isuswa futhi ithathelwa indawo entsha. Ukwengeza, ukusetshenziswa njalo kwezindawo zokuphepha ezijwayelekile kanye nokuhambisana nemithetho efanele yokuphepha kuyadingeka. Ngaphambi kokufaka, zijwayeze le mishini elandelayo: umshini wokusika wesheke impande ye-disk, hlola i-torque wrench noma i-wrench, isigqoko esiqinile, ama-caliper angaphakathi nangaphandle, i-lubricant ye-fastening device, i-reflector, i-pan root extractor, ithuluzi lokusika izimpande ze-pan, ama-calipers we-vernier , njll
2. Ukuhlanza nokuhlola
1) Khulula kancane kancane i-gland nut yebhokisi lokugxusha ukuze ukhulule yonke ingcindezi esele ekuhlanganiseni kwempande yepani;
2) Susa noma yiziphi izimpande ezindala futhi uhlanze kahle ibhokisi lokugxusha le-shaft / induku;
3) Hlola ukuthi i-shaft/induku inokugqwala, ukubola, imihuzuko noma ukuguga ngokweqile;
4) Hlola ukuthi ngabe ezinye izingxenye zine-burrs, imifantu, ukugqoka, zizonciphisa impilo yempande;
5) Hlola ukuthi ibhokisi lokugxusha linemvume enkulu kakhulu, kanye nokugqama kwe-shaft/induku;
6) Faka esikhundleni izingxenye ezinamaphutha amakhulu;
7) Hlola impande endala njengesisekelo sokuhlaziya ukwehluleka ukuthola imbangela yokwehluleka kwasekuqaleni kwempande.
3. Linganisa futhi urekhode ububanzi bomgodi/induku, indawo yokungena nokujula kwebhokisi lokugxusha, kanye nebanga ukusuka phansi kuya phezulu kwebhokisi lokugxusha lirekhodwa lapho indandatho ivalwa ngamanzi.
4, khetha impande
I-1) Qinisekisa ukuthi impande ye-pan ekhethiwe kufanele ihlangabezane nezimo zokusebenza ezidingwa uhlelo kanye nemishini;
2) Ngokusho kwamarekhodi okulinganisa, bala indawo ephambanayo yempande kanye nenani lamasongo ezimpande adingekayo;
3) Hlola impande ukuze uqinisekise ukuthi azikho iziphambeko;
4) Ngaphambi kokufaka, qinisekisa ukuthi izinto zokusebenza nezimpande zihlanzekile.
5, ukulungiswa kwendandatho impande
1) Hlukanisa izimpande ngokugoqa izimpande ku-shaft yobukhulu obufanele, noma usebenzisa umsiki wendandatho yezimpande ezilinganisiwe; Sika IZIMPANDI ZEDISCSI Ngokuhlanzekile UZIBE EBUTH (ISIKWENI) NOMA IMITHA (30-45 DEGREES) NJENGOBA KUDINGEKA, INDANDATHO EYODWA NGESIKHATHI, FUTHI HLOLA USAYIZI WOMHLABA NOMA ISIQINISO.
2) Amadiski abunjiwe aqinisekisa ukuthi usayizi wendandatho ulingana ncamashi ne-shaft noma isiqu. Uma kunesidingo, sika izindandatho zokupakisha ngokulandela imiyalelo yokusebenza komenzi noma izidingo.
6. Faka impande yediski ngokucophelela iringi eyodwa ngesikhathi, futhi uzungeze iringi ngayinye ku-shaft noma isiqu. Ngaphambi kokufaka iringi elandelayo, qinisekisa ukuthi iringi isendaweni ngokuphelele ebhokisini lokugxusha, futhi iringi elandelayo kufanele inyakaze, okungenani iqhelelane ngamadigri angu-90, ngokuvamile ibe ngama-degree angu-120. Ngemva kokufakwa kwendandatho yokugcina, qinisa i-nati yepompo yamafutha e-slag yokucindezela okuphezulu ngesandla, bese ucindezela indlala ngokulinganayo. Uma kukhona indandatho yokuvala amanzi, kufanele kubhekwe ukuthi ibanga ukusuka phezulu kwebhokisi lokugxusha lilungile. Qinisekisa futhi ukuthi i-shaft noma isiqu singajikeleza ngokukhululekile.
7. Lungisa impande ye-pan ye-high-pressure slag oil pump
1) futha ngempande yepani
(1) Qhubeka uqinisa nati lendlala ngesandla;
(2) Ngemva kokuvula iphampu, lungisa nati legland ukuvumela ukuvuza okwengeziwe;
(3) Kancane kancane qinisa nati legland ukuze wehlise kancane kancane ukuvuza kuze kube yilapho ukuvuza kufinyelela ezingeni elamukelekayo;
(4) Uma ukuvuza kuma ngokuzumayo, inati legland kufanele liboshwe emuva futhi lilungiswe ukuze kuvinjwe ukushisisa ngokweqile kwepani;
(5) Lungisa izinga lokuvuza ukuze ufinyelele esimweni esizinzile.
2) Xhumana nomkhiqizi wamakhoyili noma umnyango wezobuchwepheshe webhizinisi mayelana nemithetho yetorque noma iphesenti lokuminyanisa levalvu enempande yekhoyili, bese uqinisa inadi lendlala ngale ndlela elandelayo:
(1) Faka i-torque kumantongomane edlala ku-30% wetorque egcwele noma iphesenti lokuminyanisa iqembu;
(2) vula futhi uvale ngokuphindaphindiwe i-valve izikhathi eziningana, lapho i-valve isendaweni evaliwe, sebenzisa yonke i-torque;
(3) Phinda isinyathelo (2)3 noma 4 izikhathi.
8. Qinisa futhi ubeke esikhundleni futhi ngemva kwamahora amaningana okusebenza, hlola isimo sokulungiswa kwendlala yephampu yamafutha e-slag yokucindezela okuphezulu, yiqinise lapho kudingekile, bese ubuyisela impande ye-pan lapho indlala ingakwazi ukulungiswa ngokuqhubekayo.
