Matambudziko Anowanikwa Evhavha - Yakakwira Kudzvanya Drop inotsanangura kuisirwa uye kugadziriswa kweyakanyanya kumanikidza slag pombi uye mavharuvhu.
Nekuda kwemusiyano uripakati peUPSTREAM NEKUDINIRA kuzasi, KUFAMBA nepakati pevhavha KUNONZI PRESSURE DROP Nekuda kwemusiyano uripo pakati pekukwira nekudzika kwemvura, kuyerera kuburikidza nevharuvhu kunonzi kudonhedza kudonhedza OP, kana kusiyanisa kudzvanywa. Kana SIZE YEMUTSARA IRI MUMWEWO UUPSTREAM UYE DOWNSTREAM YEVHAVIRI UYE KURUMBIRWA KWAKAITA KUCHINYORA, VHIRIVIRI INOFANIRA KUITA KURASIKA KWEFRICTIONAL KUDZORETSA FLUID DZINIKI KUTI IBURE KUFANANA. Chikamu chekurasikirwa kwevhavha kunokonzerwa nekukwesha kwemvura uye madziro evharuvhu. Nekudaro, kukwesha uku kudiki uye hakugone kuburitsa kudonhedza kwakaringana kwemvura yakakodzera. Imwe nzira inoshanda yekugadzira yakakosha kurasikirwa muvharuvhu iri kuburikidza nekupuruzira mumuviri wevharuvhu. Nokuti mavhavha akawanda AKAgadzirirwa kubvumira chikamu chevhavha kuti ive NARROWER THAN THE LINE, inogona kupa nyore THROttLING muFLUID layer. Nekuda kweMURAIRO WEKUCHENGETEDZA, SEZVO FLUID INOSVIKA PAVIRIVITI, kumhanya KWAYO kunowedzera KUTI FLUID YOSE IBUDZE PAVIRIVIRI.
Pane zvinopesana, kudonha kunoenderana nekudzvinyirira kunoitika (Mufananidzo 9.1). Ukama hwakasiyana pakati pekumanikidza uye kukurumidza kunoratidzwa neBernoulli's formula seinotevera:
Kumhanya kwepamusoro-soro uye kudzvinyirirwa kwakaderera kunoitika zasi kwekakumanikana kwemutsipa, kunonzi chikamu checonstriction. Mufananidzo 9.2 INORATIDZA KUTI CHIKAMU CHECONTRACTILE HACHISI CHEKUZVARURA CHEGA, ASI CHIRI KURE PASI CHEKUPUMIRIRA KUNOKASINANA NEKUDIKIRWA KWAKO. Kana kukurumidza kwechikamu chechibvumirano chiri chepamusoro-soro, nzvimbo yekuyerera yerogistics layer ndiyo shoma. Mushure mechikamu chechibvumirano, kuyerera kunononoka uye kudzvinyirira kunokwira zvakare, asi hakusviki kune yepakutanga kukwira kwepamusoro kukosha kukosha. Musiyano PAKATI peUPSTREAM pressure uye DOWNSTREAM pressure INODA kufirwa nekurasikirwa AS Logistics inoyerera nemuvharuvhu uye inonzi PERMANENT pressure DROP. Musiyano wekumanikidza pakati pekumanikidza pachikamu chechibvumirano uye kudzvanywa kuzasi kunonzi kudzoreredza. Dhiagiramu yakapfava yekudonha kwechigarire kudonha uye kudzoreredza kudzoreredzwa kunoratidzwa muMufananidzo 9.3. Kuiswa chisimbiso kunoshanda kwepamusoro-kumanikidza slag pombi uye mavharuvhu zvinoenderana nemamiriro ese echikamu chimwe nechimwe. Kunyanya kutarisisa kunofanirwa kubhadharwa kune vimbiso yekuti iyo midziyo inoda kutsiviwa kwemudzi wepani yakave yakasarudzika yakasarudzika maererano nenzvimbo uye system isati yaiswa pani mudzi. Izvi zvinotevera zvinoshandiswa kutungamira vashandi vekuchengetedza, mainjiniya, uye maassembler kuti aise nemazvo uye kugadzirisa pani mudzi.
Kuiswa chisimbiso kunobudirira kwepamusoro-soro slag pombi uye valve kunoenderana nemamiriro ezvinhu ega ega ega. Kunyanya kutarisisa kunofanirwa kubhadharwa kune vimbiso yekuti iyo midziyo inoda kutsiviwa kweiyo pani midzi yakave yakasarudzika yakasarudzika maererano nenzvimbo uye system isati yaiswa pani mudzi. Izvi zvinotevera zvinoshandiswa kutungamira vashandi vekuchengetedza, mainjiniya, uye maassembler kuti aise nemazvo uye kugadzirisa pani mudzi.
1. Zvishandiso zvakakosha, high-pressure slag mafuta pombi uye chigadziro chekuisa chinofanira kushandiswa kusimudzira gland nut apo midzi yekare yepani inobviswa uye inotsiviwa neimwe itsva. Uye zvakare, kushandiswa nguva dzose kwezvivakwa zvekuchengetedza zvakajairwa uye kutevedzera yakakodzera mitemo yekuchengetedza kunodiwa. Usati wagadzikwa, zvijaidze nemidziyo inotevera: muchina wekucheka cheki disk midzi mhete, tarisa torque wrench kana wrench, hard hat, yemukati nekunze caliper, lubricant yekusimbisa mudziyo, reflector, pan root extractor, pan root cutting tool, vernier calipers. , nezvimwewo
2. Kuchenesa uye kuongorora
1) Zvishoma nezvishoma sunungura gland nut yebhokisi rekuputira kuti usunungure zvose zvakasara zvinomanikidzwa mumusangano wepani;
2) Bvisa chero midzi yekare uye nyatsochenesa bhokisi rekuisa shaft / tsvimbo;
3) Tarisa uone kana shaft/tsvimbo ine ngura, dents, makwara kana kupfeka zvakanyanya;
4) Tarisa kana zvimwe zvikamu zvine burrs, kuputika, kupfeka, ivo vanoderedza hupenyu hwemudzi;
5) Tarisa uone kana bhokisi rekupfekedza rine yakakura kwazvo clearance, uye shaft/rod eccentricity;
6) Tsiva zvikamu zvine hurema hwakakura;
7) Tarisa mudzi wekare sehwaro hwekukundikana kuongororwa kuti uwane chikonzero chekukundikana kwekutanga kwemudzi.
3. Kuyera uye kunyora dhayamita ye shaft / tsvimbo, aperture uye kudzika kwebhokisi rekuputira, uye chinhambwe kubva pasi kusvika kumusoro kwebhokisi rekuisa rinonyorwa kana mhete yakavharwa nemvura.
4, sarudza mudzi
1) Ita shuwa kuti iyo yakasarudzwa pani midzi inofanirwa kusangana nemamiriro ekushanda anodiwa nehurongwa nemidziyo;
2) Maererano nemarekodhi ekuyera, verenga nzvimbo ye-cross-sectional yemudzi uye nhamba yezvindori zvemidzi inodiwa;
3) Tarisa mudzi kuti uone kuti hapana chakaremara;
4) Usati waiswa, ita shuwa kuti midziyo nemidzi zvakachena.
5, kugadzirira kwemudzi wemhete
1) Ruka midzi nekumonera midzi pashaft yehukuru hwakakodzera, kana kushandisa calibrated mudzi ring cutter; Zvakacheneruka DAI DISC ROOTS MUBUTT (SQUARE) KANA KUTI MITA (30-45 DEGREES) SEZVINODIWA, RING IMWE PANGUVA, UYE TARIRA UKUZE INE SHAFT KANA STEM.
2) Madhisiki akaumbwa anovimbisa kuti saizi yemhete inoenderana chaizvo neshaft kana dzinde. Kana zvichidikanwa, cheka zvindori zvekurongedza maererano nemirairo yekushanda yemugadziri kana zvinodiwa.
6. Isa dhisiki mudzi nokungwarira mhete imwe panguva, uye komberedza mhete imwe neimwe pashaft kana dzinde. Usati waisa rin'i inotevera, ita shuwa kuti mhete yanyatsogara mubhokisi rekuisa, uye rin'i inotevera inofanira kudzedzereka, ingangoita 90 madhigirii akasiyana, kazhinji 120 madhigirii. Mushure mokunge mhete yekupedzisira yaiswa, simbisai nut ye-high-pressure slag mafuta pombi nemaoko, uye shandisa gland zvakafanana. Kana pane chisimbiso chemvura, inofanira kuongororwa kuti chinhambwe kubva kumusoro kwebhokisi rekuisa chakarurama. Iva nechokwadi zvakare kuti shaft kana dzinde rinogona kutenderera zvakasununguka.
7. Gadzirisa pani mudzi we-high-pressure slag mafuta pombi
1) pombi ine pani mudzi
(1) Ramba uchisimbisa gland nut neruoko;
(2) Mushure mekuvhura pombi, gadzirisa gland nut kuti ubvumire kubuda zvishoma;
(3) Zvishoma nezvishoma simbisa gland nut kuti zvishoma nezvishoma uderedze kudonha kusvikira kudonha kwasvika padanho rinogamuchirwa;
(4) Kana kudonha kwakamira kamwe kamwe, gland nut inofanira kukwizwa kumashure uye kugadziridzwa kudzivirira kupisa kwepani;
(5) Rongedza mwero wekudonha kuti usvike pakugadzikana.
2) Bvunza mugadziri wemakoiri kana dhipatimendi rehunyanzvi rebhizinesi nezve torque mirau kana compression muzana yevharuvhu ine coil mudzi, uye simbisa gland nati sezvinotevera:
(1) Isa torque kune gland nut kusvika 30% ye torque yakazara kana bato compression percentage;
(2) kuvhurika uye kuvhara vharavha kakawanda, kana vharuvhu iri munzvimbo yakavharwa, shandisa torque yese;
(3) Dzokorora danho (2) 3 kana 4 nguva.
8. Simbisa uye shandura zvakare mushure memaawa akawanda ekushanda, tarisa kugadzirisa mamiriro egland yepombi yepamusoro-slag mafuta pombi, simbisa pazvinenge zvichidiwa, uye shandura pani midzi apo gland haigoni kuchinjwa.
