Chigadziko chesimbi chinopa matombo simba rinogara kwenguva refu

Chigadziko chesimbi chinobereka matombo chinogara kwenguva refu

Tsananguro pfupi:

Matombo esimbi anogadzirwa ne chrome alloy alloy ayo anogadziriswa nekukurumidza mushure mekunyunguduka. Mushure mekupiswa, anoonekwa aine hunhu hwakanaka hwemakanika, kusimba kwakanaka, kuramba kuneta zvakanyanya, kushanda kwenguva refu, kushandiswa kushoma nezvimwewo. 30% ichachengetwa. Inonyanya kushandiswa mukucheka granite, kuputira jecha uye kupfura.

Chigadziko chesimbi chinogadzirwa nesimbi yesimbi ine kabhoni, inoshandiswa kugadzira mabhora, maroller nemabhearing rings. Simbi ine kuomarara kwakafanana uye kwakakwirira uye nguva yekutenderera, pamwe nekusimba kwakanyanya. Kufanana kwemakemikari, huwandu uye kupararira kwezvinosanganisira zvisiri zvesimbi uye kupararira kwemakabhobidhi esimbi inobereka zvakaoma kwazvo, inova imwe yezvinodiwa zvakanyanya mukugadzirwa kwesimbi yese.

Tsananguro yeChigadzirwa

Matombo esimbi anogadzirwa ne chrome alloy, ayo anogadziriswa nekukurumidza mushure mekunyunguduka. Mushure mekupiswa, anoonekwa aine hunhu hwakanaka hwemakanika, kusimba kwakanaka, kuramba kuneta zvakanyanya, kushanda kwenguva refu, kushandiswa kushoma nezvimwewo. 30% inoponeswa. Inonyanya kushandiswa mukucheka granite, kuputira jecha uye kupfura.

Matombo esimbi ane simbi inokosha - chromium, kuburikidza nekugadzirwa kwakasiyana, chimiro chakanaka chesimbi, zvidimbu zvechigadzirwa zvizere, kuomarara kwakafanana, nguva refu yekutenderera, zvinogona kuvandudza mwero wekupora (kuora kwejecha kunoderedza zvishoma nezvishoma), kuitira kuderedza mwero wekushandiswa kweabrasive kusvika ku30%.

Munda weKunyorera

Kutakura simbi yejecha kuputika
Hunhu hwesimbi yesimbi inoshandiswa pakugadzira jecha rinoputika hunokanganisa zvakananga hunhu uye mutengo wakazara maererano nekushanda zvakanaka kwejecha rinoputika, girder coating, kupenda, kinetic energy uye abrasive consumption. Nekuburitswa kwePSPC (PSPC), pane chikumbiro chepamusoro kune piece wise jecha rinoputika. Saka, hunhu hwesimbi yesimbi hwakakosha zvikuru pakugadzira jecha.

Magranules emakona ekugadzira jecha
Kuputika kwejecha remakona maviri pabhokisi remugaba mushure mekunge rapwanyika. Chenesa nzvimbo yakapwanyika uye panguva imwe chete kuti pamusoro pebhokisi pave nekuomarara uye kuwedzera kupenda kunodzivirira ngura, kuitira kuti ukwanise kushanda kwenguva yakareba pakati pengarava, chassis, mota yekutakura zvinhu nemotokari dzechitima.
Chigadziko chesimbi chakakombama chekushandisa magetsi emumunda.
Chigadzirwa chemagetsi emumunda chine chikumbiro chaicho chekugadzirisa kutsvuka uye kuchena kwenzvimbo yacho. Mushure mekugadzirisa pamusoro pemagirini esimbi, vanofanirwa kuchinja mamiriro ekunze kwenguva yakareba. Saka, kuputika kwejecha remagirini esimbi kunokosha zvikuru.

Granite steel grit uye stone grit
Kucheka matombo uchishandisa granite cutting steel grit uye stone cutting grit kubva mumvura inoyerera. Mukuita kwekucheka, stone sawing grit haina makemikari anochinja uye ine mabhenefiti ekusava nekemikari pakushanda kwematombo, hapana kupisa kunochinja, kutetepa, kunyatsoita basa, nzvimbo yekucheka yakatsetseka, kuchena uye kusasvibiswa, nezvimwewo.

Simbi ine kona yesimbi yekuputika kwejecha reLocomotives
Mushure mekupedza kugadzira kana kugadzirisa, pamusoro pemarobhoti emota panofanira kupendwa (kusanganisira undercoat, pakati, finishing coating nezvimwewo), kuti robhoti rive nechimiro chakanaka uye kuti rishande zvakanaka. Kusarudzwa kwesimbi ine angle grit kwakakosha zvikuru pakugadzirisa pamusoro, izvo zvinokanganisa mashandiro erobhoti pakudzivirira kutsemuka, kuramba kupinda kwerobhoti uye kusakwanisa kuoxidation.

Chidimbu chesimbi chakakombama chechimiro chesimbi
Kumaumbirwo esimbi, kumhanya kwengura kunonyanya kuenderana nehunyoro hwemhepo uye kuumbwa kwayo nehuwandu hwezvinosvibisa mumhepo. Kuti iwedzere hupenyu hwayo, simbi inofanira kuda kugadziriswa kweAngular steel grit blasting surface, uye nekupfapfaidza kuti igadzire firimu rekudzivirira pamusoro pesimbi kudzivirira nekuderedza ngura yesimbi.

Mugadziri weSimbi wekugadzira sandblasting yePort Machinery
Kuvakwa kwechiteshi chengarava kunoshandisa chivakwa chesimbi zvakanyanya. Saka, chikumbiro chesimbi chekudzivirira ngura chakakwira zvikuru. Michina yechiteshi inowanzo sangana nemamiriro ezvinhu akasiyana. Semuenzaniso, mhepo ine hunyoro mugungwa, iyo inoita kuti zvivakwa zvesimbi zvive nengura yakadzika. Muchiitiko ichocho, jecha rinoputika uye rinoputira zvinodiwa kuchengetedza michina yechiteshi. Saka kugadzirwa kwesimbi yakanaka kwakakosha zvikuru.
