Shot blasting kusimbisa mhedzisiro uye kushandisa
1. Mhedzisiro yepfuti blasting kusimbisa
Shot blasting kusimbisa inotonhora yekushanda pamusoro pekusimbisa nzira yesimbi. Inoshandisa muchina unopfutidza kudzora kukanganiswa kwe-zvinomhanyisa mapurojekiti pamusoro pechishandiso, zvichikonzera deformation yepurasitiki mukati me layer. Izvi zvinovandudza iyo microstructure uye kushushikana mamiriro eiyo workpiece, nekudaro ichiwedzera kuita kwayo. Iwo core effects anosanganisira:
A. Kuvandudza hupenyu hwekuneta uye kudzvanyirira kutanga kwe crack
Iyi ndiyo yakakosha kukosha kwepfuti blasting kusimbisa: Nekugadzira yunifomu uye inodzoreka yakasara compressive stress layer pamusoro peiyo workpiece kuburikidza nepfuti blasting, inopesana neanotsinhanisa tensile kushushikana iyo workpiece inoiswa, nekudaro ichivharira chizvarwa uye kuwedzera kwekuneta kutsemuka. Pakushushikana-nezvikamu zvakasangana zvakaita semagiya nezvitubu, hupenyu hwekuneta hunogona kuwedzerwa kakati wandei kana kanoverengeka, zvichideredza zvakanyanya njodzi yekutyoka mazino uye kutadza kutsemuka.
B. Kunatsiridza diki -kushanda uye kuwedzera kusakara uye kuoma
Iko kukanganiswa kwemapurojekiti kunoita kuti zviyo zvesimbi zviri pamusoro pedenga zvive zvakapfava uye chimiro chakaomesesa, zvakananga kunatsiridza kuoma kwepasi uye kupfeka kuramba; panguva imwe cheteyo, inogona kupfavisa maturusi madiki madiki madiki nemaburrs akasiiwa nemuchina, kubvisa diki -zvakakanganisika, uye kuderedza kushushikana.
C. Synergistically kusimudzira anti-kuora nekunamira kwekunamira
Kune rimwe divi, iyo yakasara yekumanikidza kushushikana inogona kuvharira nzira yekupinda ye corrosive media, ichivandudza iyo workpiece kuramba kushushikana nekuora; nerumwe rutivi, kurapwa kwekuputika kwepfuti kunogona kuita Sa2.5 mwero wehutsanana hwepasi, kutsiva nzira dzechinyakare dzekugezeswa kweasidhi kudzivirira njodzi yehydrogen embrittlement, kuve nechokwadi chekunamira kweanotevera mabhachi kune ISO 1 mwero, uye kuwedzera zvakanyanya hupenyu hweanodzivirira{2}}mabhanhire ekuora.
D. Kuvandudza dimensional kugadzikana uye kuderedza deformation ngozi
Iyo pfuti yekuputika maitiro inogona kuparadzira zvakaenzana kushushikana kwasara mukati meiyo workpiece, kukwidziridza mamiriro ekuparadzira kushushikana, kuderedza mukana we deformation uye kutsemuka panguva inotevera kugadziridzwa uye sevhisi, uye kunatsiridza iko kwakaringana uye kugadzikana kwedimensional yechaiyo zvikamu.
2. Mashandisirwo makuru ekusimbisa kuputika kwepfuti:
Kusimbaradza kwepfuti kwakashandiswa zvakanyanya mu-minda yekugadzira zvinhu zvine kuvimbika kwakanyanya uye zvinodiwa zvehupenyu. Mamiriro ezvinhu akafanana anosanganisira:
A. Kugadzira mota (kuverengera 34% yemusika kudiwa, iyo yakakura application ndima)
Kurapwa kwakakosha kwezvinhu zvakakosha zvakaiswa pakuchinjana mitoro: zvitubu zvekumisikidza, zvitubu zvevharuvhu, magiya ekufambisa, injini crankshafts, tsvimbo dzekubatanidza, chassis mabhuraketi, nezvimwe, kugadzirisa marwadzo eindasitiri akadai sekuputsika kwekuneta kwechitubu, kutsemuka kwegiya / pitting, uye crankshaft kuneta kutadza, uye idanho rinodiwa pakugadzirwa kwezvigadzirwa zvemotokari.
B. Muchadenga
Kurapwa kwezvikamu zvakakosha pasi pemamiriro ezvinhu akanyanya: giya rekumhara ndege, turbine blades, fuselage structural components, engine discs and shafts, nezvimwewo, munzvimbo yakakwirira-yakadzika uye yakaderera-tembiricha, -yakakwirira{3}}nzvimbo dzinotakura zvinhu, kusimbisa kusaneta uye kusagadzikana kwekuora kwekusagadzikana kwezvikamu zvendege, kuita kuti ndege isachengeteke.
C. Kuvaka michina uye inorema midziyo
Kurapwa-kupfekwa kwemutoro-kusingagadzirike: mabhaketi ekuchera, marata e crawler, mazino anotakura zvinhu, macrane structural components, zvichingodaro, izvo zvisingabvisi zvikero zveoxide zvepasi chete asiwo zvinowedzera kuoma kwechiso uye kusapfeka, zvakasanganiswa neteknolojia yekupfapfaidza inopisa, inogona kuwedzera hupenyu hwemazino emubhaketi ka8.
D. Mhepo simba uye simba chikamu
Kurapa magiya egiya remhepo, shongwe yemhepo, mabhengi, zviumbwa zvesimba renyukireya, zvichingodaro, kugadzirisa kuneta kwezvikamu zvesimba remhepo pasi penguva refu-inochinjana mitoro, uku uchiwedzera kunamira kwekuvharisa uye kudzivirira{2}}kuora hupenyu hwezvivakwa zveshongwe nezvimwe zvakakura-zvikero zvesimbi{4}zvichienderana nezvinodiwa zvepadoor
E. Chitima chekufambisa
Mabatirwo ezvibatiso zvenjanji, ekisi, magiya bhokisi, zvikamu zvemuviri wemotokari, zvichingodaro, kuona kuvimbika kwezvikamu zvekutakura njanji pasi pe-frequency vibration uye{2}}zvinorema, kuderedza mari yekugadzirisa.
F. Mishonga uye zvinhu zvakakosha
Kune titanium alloy alloy artificial joints uye implants, pfuti blasting treatment inoumba nanocrystalline layer pamusoro, zvakanyanya kuvandudza biocompatibility; panguva imwecheteyo, inosimudzira kupfeka uye kusagadzikana kwekusagadzikana kwemidziyo yesimbi yekurapa, kuchinjika kune inosimwa nharaunda mumuviri wemunhu.
G. Huru-chimiro chesimbi chinodzivirira-corrosion-kutanga kurapwa
Kurapa kwepfuti kusati kwaiswa zvivakwa zvesimbi zvakakura-semabhiriji, ngarava, matangi, uye mapaipi, kutsiva kubviswa ngura kweasidhi yechinyakare, izvo zvinongonatsiridza kunamira kwemavara asi zvinodzivirira kukuvadzwa kwehydrogen, inova nzira ye{1}}yekutanga kurapa{2}}mapurojekiti anodzivirira kuparara.
