Indasitiri yeMigodhi

Kuongororwa kweMashandiro eIndasitiri uye Kuongororwa kweTekinoroji yeLaser Cladding

1. Kuongorora Nhoroondo yeMaindasitiri

1. Kukanganisa Kwenzvimbo Dzebasa Dzakaoma Pamichina

Nzvimbo dzekuchera marasha pasi pevhu dzinopa matambudziko makuru pakugara kwenguva refu kwemuchina. Nehunyoro hunowanzo pfuura 90% uye kuvapo kwemagasi anoparadza akadai seH₂S neSO₂, zvikamu zvesimbi zvinokurumidza kuparadzwa nemagetsi. Semuenzaniso, masilinda e hydraulic prop, akakosha pakuchengetedza kugadzikana kwemugero, anowanzo batwa nengura pamusoro pevhu izvo zvinokanganisa mashandiro ekuvhara, zvichikonzera kutadza kushanda kwe hydraulic system. Pamusoro pezvo, zvidimbu zveguruva remarasha (Mohs hardness 3-4) zvinoshanda sezvinhu zvinogumbura, zvichikonzera kupera kwakanyanya pazvikamu zvinotumira senge sprockets uye scrapers. Guruva remarasha rinomhanya zvakanyanya rinogona kuderedza hupenyu hwebasa rezvikamu izvi kusvika ku40% zvichienzaniswa nenzvimbo dzakachena.

2. Nzira dzeKukundikana kweChikamu

(1) Kupfeka Kuneta: Kuzadza zvinhu nemaoko kunokonzera kutsemuka kweganda pamusoro pezvinhu. Mushure memaawa angangoita chiuru ekushanda, matombo aya anogona kupinda nepakati pe 0.5mm, zvichikonzera kutsemuka kwezvinhu uye kuora kwebasa.

(2) Kubvisa Kupenda Kwekupfeka: Matanda echinyakare ane ma electroplated (semuenzaniso, hard chrome plating) anobatana zvisina kusimba ne substrates (20-30 MPa), zvichiita kuti zvive nyore kukwenywa kana zvarova. Kusiyana neizvi, laser cladding inopa simba re 400-600 MPa, zvichiita kuti irambe yakanamatira kwenguva refu.

2. Mabhenefiti eTekinoroji yeLaser Cladding

Kufukidza kweLaser yekunze

Maitiro aya anobudirira pakugadzira machira anodzivirira kupera uye anodzivirira ngura pazvikamu zvemubato zvakaita semasilinda netsvimbo dzepiston. Mabhenefiti makuru anosanganisira:

● Kuwanda Kwemvura Yakaderera: Zvisingasviki 5%, zvichichengetedza hunhu hwepakutanga hwezvinhu.

● Kuchinja Kushoma: Nzvimbo dzinokanganiswa nekupisa dzinowanzova

● Kushanda Nesimba Kwezvinhu: Kushandiswa kwehupfu kunodarika 90%, zvichideredza mitengo kana tichienzanisa nekushandisa plating yemazuva ose.

● Hunhu Hwepamusoro: Ra ≤ 6.3μm finish, zvichibvisa kudiwa kwekugadziriswa mushure menguva dzakawanda.

Kufukidza kweLaser yeMadziro Emukati

Nzira iyi yakanakira masirinda e hydraulic netsvimbo dzepiston, uye inobvumira kushandiswa kwezvipfeko zvakasiyana-siyana zve alloy (semuenzaniso, simbi isingatsvi, alloys dzakavakirwa pa nickel) dzine ukobvu hunotangira pa 0.5mm kusvika 3mm. Semuenzaniso:

● Kupfeka Simbi Isina Kusimba: Inodzivirira ngura ka5 kupfuura simbi isina chinhu munzvimbo dzine acidic.

● MaAlloys Akavakirwa paNickel: Wedzera kuomarara kubva pa200 HV kusvika pa600 HV, zvichiwedzera zvakanyanya kuramba kupfeka.

Kufukidza Kwepamusoro Kwakakombama kweLaser

Yakagadzirirwa ma geometries akaomarara akadai se sprockets nema picks, maitiro aya anopa:

● Kudzora Nzira Inoenderana Nemamiriro Ezvinhu: Inoshandisa masisitimu eCNC ane axis 5 kuti iwane ukobvu hwakafanana hwekufukidza (± 0.1mm) panzvimbo dzisina kurongeka.

● Simba reChisungo Chakakwirira: Kubatana kwesimbi kunoita kuti zvinhu zvisakwanise kubatwa nesimbi. Semuenzaniso, machira akafukidzwa papicks anoramba akasimba kunyangwe pasi pe200 J yesimba resimbi.

3. Magadzirirwo ehunyanzvi uye Magadzirirwo ekushanda

4. Chidzidzo Chenyaya: Kugadziriswa kweSirivhari yeHydraulic Prop

Mugodhi wemarasha muShanxi Province wakashuma kudzikira kwe65% kwemitengo yekutsiva masilinda mushure mekushandisa laser cladding. Maitiro aya akadzorera masilinda ane ngura (pakutanga aiva φ140mm×2.5m) kuti agadziriswe, neclad layer (NiCrBSi alloy, 1.2mm gobvu) ichiratidza:

● 86% yakaderera pakukweshana kwesimbi kupfuura simbi yepakutanga.

● Nguva refu yehupenyu hwese inowedzerwa katatu kana uchiyedzwa kupfeka zvinokuvadza.

● 100% kupasa bvunzo dzekusimbisa simba (35 MPa).

5. Mabhenefiti Ezvakatipoteredza Nehupfumi

● Kuchengetedza Zvinhu: Kufukidza neLaser kunoshandisa upfu hwe alloy hushoma ne70% kana tichienzanisa nenzira dzemazuva ano dzekuisa pamusoro.

● Kushanda Nesimba Zvakanaka: Inoderedza kushandiswa kwesimba ne40% panguva yekugadzirisa.

● Kuderedza Kubuda Kwemhepo: Inobvisa kuburitswa kwechromium ine hexavalent inobatanidzwa ne electroplating, ichienderana nemitemo yakaoma yezvakatipoteredza.

Mukupedzisa, tekinoroji yelaser cladding inopa mhinduro yakakwana yekurwisa kuora kwezvikamu munzvimbo dzakaoma dzekuchera, zvichipa mashandiro akanaka uye kuchengetedzeka zvichienzaniswa nenzira dzechinyakare.

Kushandiswa Kwenyaya
