Kugadzirisa maitiro e slag kusanganisa kuremara kwemhangura propeller

---

Anofambisa ngarava dzegungwa anonziwo thruster, chinova chinhu chakakosha kukanda gwenya remagetsi rechikepe uye chinhu chakakosha kuona kufamba kwakachengeteka kwechikepe. Mafaira anoshanda mumvura yegungwa ari pasi pemitoro yakakura yekuchinjana. Zvinoda zvakakwirira zvemuchina zvivakwa, yakakwira ngura kuneta kuramba, uye yakanakisa cavitation ngura kuramba. Kukanda zvinokanganisa zvakadai se pores uye slag inclusions hazvibvumirwe.

Propeller yakaburitswa nePTJ Shop inoshandisa chiwanikwa chemhangura, icho chinonyanya kushandiswa mukugadzira machining ngarava dzinofambisa yezvikepe zvikuru uye zvinomhanya zvikuru. Zvakanakira ayo makuru kurema uremu uye yakasimba simba. Kuneta kurwisa uye kuchenesa kusagadzikana kusagadzikana kwakanaka. Kukanganisa kwayo kwakakwira kukanda uye kugadzirisa zvinodiwa. Kana kutenderera kusiri kutorwa, zvinowirirana nezvinetso zvakaita sekuoma kwakaomarara, porosity, kutsemuka kwekushisa, uye kushomeka kwepasi-kweyekutenderera kwekubatana kuita kuchadzorerwa. . Izvi zvinotevera kurondedzerwa kwekushandiswa kweArgon arc Welding kugadzirisa slag yekuisa kuremara kweiyo propeller.

Tsananguro isina kukwana

Iyo crystalline renji yeiyo alloy alloy yakatetepa, uye vhoriyamu shrinkage yakakura, uye chiwanikwa chinewo zvinoshanda zvinhu Al, Mn, Fe, Ni, nezvimwewo, zvine hukama hwakasimba hweoksijeni. Munguva yekudurura, mvura yepamusoro-tembiricha yemvura inopinda isina kukwana yakaomeswa semende jecha ichikanda muforoma uye ichidurura system, uye huwandu hwakawanda hwemashambadziro emvura-akavakirwa sekristaro yemvura pamusoro pechikanda chinokasira kukurumidza kuita kuti ive mhute yemvura. Kana mhute yemvura ikabatana nezvinhu zvealloy, inclusions inclusions inogadzirwa. Slag. Inopfuura hafu yekukanganisa kunoonekwa mune yakaderera 0.5R-0.8R yenzvimbo yepasi; kune zvakare firimu ye-oxide inovhara iyo yese pamusoro peiyo mhinduro yemhangura panguva yekudurura, uye mhinduro yemhangura inopinda mune blade. Kubva ipapo, iyo nzvimbo yepamusoro yakaramba ichiwedzera. Nekudaro, apo mvura yemhangura payakakwira kusvika pakakwirira soro payo fosi, ndiko kuti, iyo 0.3R-0.5R gwara rekutungamira, nekuda kwekudzikisira kwakanyanya kwechikamu chakatsetseka cheye chipenga uye neaya emvura kuyerera nzira yakachinjira kumusoro kwepamusoro iyo propell shell uye iyo riser, yakakonzera yechipiri Huwandu hukuru hweiyo oxide slag uye iyo yekusiya kuramba inowedzera, kuitira kuti huwandu hwechipiri oxide slag munzvimbo ino iwedzere zvakanyanya.

Kusarudzwa kwezvinhu zvekushambidza

Welding zvinhu zvinofanirwa kusarudzwa zvinoenderana nezvinofambisa zvinhu zvine zvakafanana kuita.

Kugadzirira kusati kwasvika

Shandisa sander kugaya zviremara uye bvisa zvachose zvirema kusvika yakanaka matrix zvinhu zvioneke. Midziyo yakakodzera yekugadzirisa michina inofanirwa kugadziriswa, uye maburi anofanira kuve akatsetseka uye asina mabhureki. Wobva washandisa acetone, bhurasho resimbi, nezvimwewo kuchenesa nzvimbo yekugadzirisa iweld uye mamwe magazini mukati me20mm pamativi ese emafuta, oxides, hunyoro zvichingodaro. Dry iyo electrode kusvika ku200 ℃ uye chengeta kwe1 ~ 2 maawa.
Nekuda kweakanyanya kudziya mafambiro emhangura, kupisa kuri nyore kuparara panguva yekumonera, saka inofanira kutanga yapiswa isati yatungidzwa. Kune rimwe divi, preheating inogona zvakare kugadzirisa iyo yekushomeka yekushushikana kugovera uye kudzora njodzi yekunetseka ngura kutsemuka. Iyo preheating tembiricha haina kudzika kupfuura 150 ℃. Inogona kuve preheated nepfuti pfuti kana yemagetsi kupisa bhandi. Iyo interlayer tembiricha haifanire kupfuurisa 300 it uye inofanirwa kuchengetedzwa kusvika kumagumo kwekugadzirisa kwekugadzirisa. Iyo preheating renji kubva kune yekumonera yekugadzirisa nzvimbo haifanire kunge iri pasi pe100mm munzira dzese.

Post-weld machine

Nekuti maalloys emhangura anonyatso kunetsekana nekuora ngura, kurapwa kwekupisa kunofanirwa kuitwa kudzikamisa kushushikana mushure mekushambidza. Kugadziridza diki simbi, iwe unogona kushandisa yakapfava-gasi gasi kure kana yemagetsi waya hita kuita yemuno kurapa kushushikana kwekurapa, uye nekwako kupisa iyo yekumisikidza kugadzirisa kune annealing tembiricha. Maminitsi ekuchengetedza kupisa akakura kupfuura mamilimita echikamu pakukora panzvimbo iyoyo, ndokuzofukidzwa nejira re asbestosi. kutonhora. Mushure mekunge post-weld kupisa kurapwa kwanyoroveswa zvachose, ita ruvara rwekutarisa kusvikira mhedzisiro yekuongorora isingawane hurema senge kutsemuka, pores, nezvimwewo, uye mhando inosangana nezvinodiwa. Zvikasadaro, kugadzirisa kutenderera kunodiwa. Chekupedzisira, static balance test, calibration, pime kuyera, ukobvu kuyera, kukuya uye kupora.
Kugamuchira argon arc Welding kugadzirisa ngarava zvinofambisa uye kushandisa zvine musoro kutenderera maitiro parameter zvinogona nani kugadzirisa slag-mhando kukanganisa kweanofambisa, kuve nechokwadi kwema mechanical zvivakwa zve ngarava inofambisa zvishandiso, kuwedzera hupenyu hwebasa revaperekedza, uye nekuona kufamba kwakachengeteka kwechikepe.

Batanidza kuchinyorwa ichi: Maitiro Ekugadzirisa Slag Kuisirwa Kuremara KweCopper Propeller

Dzokorora Chirevo: Kana pasina mirairo yakakosha, zvinyorwa zvese zviri pasaiti ino ndezvepakutanga. Ndokumbira uratidze kwakabva kudhindazve: https://www.cncmachiningptj.com/, thanks!
