Chigadziko chesimbi chine zvirevo zvakajairwa zveSAE Mufananidzo Wakaratidzwa

Simbi ine grit yakajairika yeSAE

Tsananguro pfupi:

Junda Steel Grit inogadzirwa nekupwanya simbi yakapfurwa kuita zvidimbu zvekona zvinozobva zvanyoroveswa kuita kuoma kwakasiyana kuti zvishandiswe zvakasiyana, zvichiongororwa nehukuru zvichienderana neSAE Standard specification.

Junda Steel grit chinhu chinoshandiswa zvakanyanya pakugadzirisa zvidimbu zvesimbi. Grit yesimbi ine chimiro chakasimba uye saizi yezvidimbu zvakafanana. Kurapa pamusoro pezvidimbu zvese zvesimbi nesimbi grit steel shot kunogona kuwedzera kumanikidzwa pamusoro pezvidimbu zvesimbi uye kuvandudza kuramba kuneta kwezvidimbu zvebasa.

Kushandiswa kwesimbi yakachekwa nesimbi, ine hunhu hwekumhanya nekukurumidza, ine rebound yakanaka, kona yemukati uye chimiro chakaoma chebasa chinogona kuchenesa furo nekukurumidza, kupfupisa nguva yekurapa pamusoro, kuvandudza kushanda zvakanaka kwebasa, uye chinhu chakanaka chekurapa pamusoro.

Matagi eChigadzirwa

Junda Steel grit yehukukutu hwakasiyana

1.GP steel grit: Iyi abrasive, kana ichangobva kugadzirwa, inonamira uye ine mitsetse, uye mipendero yayo nemakona zvinokurumidzira kutenderera panguva yekushandiswa. Yakakodzera zvakanyanya pakubvisa oxide pamusoro pesimbi.
2. GL grit: Kunyangwe kuomarara kweGL grit kwakakwira kupfuura GP grit, ichiri kurasikirwa nemipendero nemakona panguva yekuputirwa kwejecha uye inonyanya kukodzera kurapwa kwekutanga kwekubvisa oxide scale pamusoro pesimbi.
3.Jecha resimbi reGH: Rudzi urwu rwejecha resimbi rune kuoma kwakanyanya uye runogara ruchichengetedza mipendero nemakona mukushanda kwejecha, izvo zvinonyanya kushanda pakugadzira nzvimbo dzakajairwa uye dzine vhudzi. Kana jecha resimbi reGH richishandiswa mukushanda kwemuchina wekucheka pfuti, zvinodiwa pakuvaka zvinofanirwa kutariswa pane mitengo (yakadai sekugadzirisa roll mu cold rolling mill). Iri grit resimbi rinonyanya kushandiswa mumichina yekucheka pfuti ine mweya wakamanikidzwa.

Kushandiswa kwemaindasitiri

Kuchenesa simbi yakapwanyika
Simbi yakapfura netsvina zvinoshandiswa pakuchenesa kubvisa zvinhu zvisina kusimba pamusoro pesimbi. Rudzi urwu rwekuchenesa rwakajairika muindasitiri yemotokari (motor blocks, cylinder heads, nezvimwewo)

Kugadzirira pamusoro pesimbi
Kugadzirira pamusoro pechinhu kunosanganisira kuchenesa nekushandura pamusoro. Matombo esimbi nejecha zvinoshandiswa pakugadzira pamusoro pechinhu kuchenesa pamusoro pesimbi dzakafukidzwa nesimbi, tsvina, ngura, kana pendi uye kugadzirisa pamusoro pesimbi zvakaita sekugadzira rough kuti pendi nependi zvishandiswe zviri nani. Matombo esimbi anowanzo shandiswa mumichina yekuputira mapfuti.

Kucheka matombo nesimbi
Chidimbu chesimbi chinoshandiswa pakucheka matombo akaomarara, akadai segranite. Chidimbu ichi chinoshandiswa mumafuremu makuru ane mashizha akawanda anocheka matombo egranite kuita zvidimbu zvitete.

Kuboorwa kwesimbi nejecha
Kubaya simbi nepfuti kunoreva kurova simbi kakawanda nesimbi dzakasimba. Kubaya uku kwakawanda kunoita kuti simbi ishanduke asi kunoitawo kuti simbi igare kwenguva refu. Zvinhu zvinoshandiswa mukushandisa uku zvine denderedzwa kwete denderedzwa. Chikonzero ndechekuti pfuti dzakasimba dzinodzivirira kutyoka kunoitika nekuda kwekurova kwadzo.

Simbi yekuputika kwejecha
Hunhu hwesimbi yekabhoni 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 mhando yejecha rinoputika. Saka, hunhu hwesimbi yesimbi yakakosha zvikuru pakugadzira jecha.

Mufananidzo wekona weContainer yejecha
Kuputika kwejecha resimbi rakatenderera pamusoro pebhokisi remugaba mushure mekusanganisa. Chenesa nzvimbo yakasungirirwa uye panguva imwe chete kuti pamusoro pebhokisi pave nekuoma uye kuwedzera kupenda kunodzivirira ngura, kuitira kuti ukwanise kushanda kwenguva yakareba pakati pengarava, chassis, mota yekutakura zvinhu uye mota dzechitima. Mutengo wedu wesimbi wakakwana.

Grit rakatenderera rekushandisa magetsi emusango
Chigadzirwa chemagetsi emusango chine chikumbiro chaicho chekugadzirisa grit pamusoro pemvura. Mushure mekugadzirisa grit yesimbi ine kona, inofanira kuchinja mamiriro ekunze kwenguva yakareba. Saka, grit yakatenderera yejecha pamusoro pemvura inonyanya kukosha.
