Mazano ekushandisa pfuti peening matangi
Shot blasting (sandblasting) matangi ndiwo midziyo yakakosha mukurapa kwepamusoro. Kushandiswa kwakarurama kunogona kuvimbisa kushanda zvakanaka, kunaka uye kuchengeteka. Pano takakurongera iwe seti yakazara yemazano ekushandisa kubva pakugadzirira, kushanda kusvika kugadzirisa.
Core musimboti: Chengetedzo kutanga
Shot peening Operations inoburitsa huwandu hukuru hweguruva, ruzha uye rebound zvinhu, uye matanho ekudzivirira anofanirwa kutorwa.
Zvidziviriro zvemunhu (PPE) : Pfeka maski anotsikirirwa nemhepo-yakapihwa guruva (masiki haafanire kushandiswa sechinzvimbo), anti-kupwanya uye anti{2}}shangu dzinodzivirira kuboora, anti-abrasion uye{4}magirovhosi anodzivirira kubaya (pfuti inoputika magurovhosi kana magurovhosi eeather), eamuffs.
Kuparadzana kwezvakatipoteredza: Shanda muimba inoputika yakavharwa kana kuti ine huruva{{0}maketeni ekudzivirira kuti uone kushanda kwemazuva ese kwemhepo nekubvisa huruva.
Sandblasting tank inspection: Cheki chekuchengetedza chinofanira kuitwa pamberi pese kushandiswa.
Tsananguro yakadzama yemazano ekushandisa
I. Gadziriro Kusati Kwaitwa Tangi Yejecha
Matanho{{0}mashanu eNzira yekuongorora tangi reSandblasting
Mapaipi nemajoini: Ongorora pombi yemhepo, pombi inoputika nejecha, uye majoini ese akasakara, akabvinza, kana kuregedzera.
Tangi muviri uye chisimbiso: Tarisa muviri wetangi kune chero akatsemuka uye simbisa kuti zvindori zvekuisa chisimbiso (kunyanya idzo dziri pabutiro rezasi) dzakasimba, dzakachena uye dzakaiswa nemazvo. Iyi ndiyo kiyi yekudzivirira kubuda kwemhepo nejecha.
Mavharuvhu uye ma controller: Tarisa uone kana vharuvhu yekuburitsa, vharafu yekupinza uye jecha rekuburitsa vharafu inoshanda zviri nyore. Tarisa kuti remote control (kana iripo) iri kushanda nemazvo.
Nozzle: Tarisa mamiriro ekupfeka emuromo. Kunyanya kupfeka (maburi emukati akakurisa kana kubuda{-kwe{2}}kutenderera) kunoderedza zvakanyanya kunaka kwekuchenesa pamwe nemhepo. Inofanira kazhinji kuchinjwa kana ichipfeka kusvika 1.5 nguva yepakutanga gomba dhayamita.
Abrasive: Shandisa maabrasives akaoma, akachena uye akakodzera saizi (senge simbi inopfura, magirazi mabhero, brown corundum, nezvimwewo). Damp abrasives inogona kukonzera kuvhara uye kuoma.
Kurodha chaiko uye kudzvanya
Dzima gasi sosi: Ita shuwa kuti vharafu huru yekupinza iri munzvimbo yakavharwa.
Chengetedzo kudzvinyirirwa kuzorora: Vhura vharafu yekuburitsa kuti usunungure yakasara kudzvanywa mujecha rejecha.
Loading: Vhura chivharo chekudyisa uye takura abrasive kusvika 70% -80% yehuwandu hwakayerwa (kusiya nzvimbo yemhepo yakamanikidzwa). Mushure mekutakura, ita shuwa kuti chivharo chekuvharisa chakasimbiswa nemazvo.
Gadzira kudzvanywa: Kutanga, vhara vharafu yekupedza, wozovhura zvishoma nezvishoma iyo huru yekupinza vheji kuti zvishoma nezvishoma uwedzere kudzvanywa mukati me tangi kune kushanda nesimba.
Ii. Operations panguva yekugoverwa
Chengetedza yakanakisa Angle uye chinhambwe
Angle: Kubvisa ngura uye kubviswa kwependi, iyo Angle pakati pemhuno nenzvimbo yekushanda ingangoita 70℃kusvika 80 degree. Kuti usimbise, inofanira kuitwa maererano nezvinodiwa nemaitiro (kazhinji pedyo nepamusoro).
Kureba: Kazhinji inochengetwa pa15 kusvika ku30 centimita. Kunyanya kuswedera kunogona kukuvadza zviri nyore substrate uye nozzle, nepo kure zvakanyanya kunozoguma nekuderera kushanda zvakanaka. Ramba uchifamba uchimhanya kudzivirira kupfuudza-kupfapfaidza kana kusakwana kuchenesa mune dzimwe nzvimbo.
Kudzvinyirira uye Kuyerera kutonga
Gadzirisa kudzvanywa kune nhanho yakakodzera maererano neyakagadzirwa yebasa, rudzi rweabrasive uye zvinodiwa zvekuchenesa. Haisi iyo iyo iyo yakakwirira kumanikidza, zviri nani. Iyo rebound inokonzerwa nekumanikidza yakawandisa ichave yakanyanya kuoma.
Iyo abrasive flow rate inogona kudzorwa kuburikidza neremote control kana jecha rekuburitsa vharafu kuti uwane yunifomu yekuchenesa maitiro.
Kuvhara mazano ekudzivirira
Nguva dzose chengetedza abrasive yakaoma.
Kana tangi yejecha ikaerekana yamira kuburitsa jecha panguva yekushanda, tanga wavhara jecha rekuburitsa vharafu, wozunza zvishoma pombi yejecha kana kurova tangi zvinyoro nyoro kuyedza kuparadzira rinogona kuumbwa "zambuko rejecha".
Kana isingabatsiri, zvino tarisa mushure mekuora mwoyo maererano nekuchengetedza maitiro.
Kuona-nguva chaiyo
Ngwarira kutarisa maitiro ekuchenesa uye mamiriro eguruva. Kusaita zvakanaka kunogona kunge kuri nekuda kwekupfeka kwenozzle, kusakwana kudzvanywa kana kusachena abrasive.
Teerera inzwi remudziyo. Ruzha rusina kujairika runogona kuratidza kubuda kwegasi kana kutadza kwechikamu chemukati.
Iii. Post-Kugadzirisa basa
Safe pressure relief uye tank kuchenesa
Mushure mekuvhiyiwa kwapera, tanga wavhara jecha rekuburitsa vharafu uye vheruvhu yekupinda mhepo.
Vhura vharuvhu yekuburitsa kuti usunungure kumanikidza kwese mukati metangi (reset gauge yekumanikidza kusvika zero).
Mushure mekusimbisa kuti hapana kumanikidzwa, vhura chivharo chekudyisa uye uchenese zvakasara abrasive uye guruva mukati metangi. Zvinonyanya kukosha kubvisa abrasive mumamiriro ekunze akanyorova.
Kuchenesa uye kugadzirisa
Chenesa chidzitiro chesefa, chisimbiso chepamusoro uye maburi ekubuda.
Tarisa mapfekero ezvikamu zvese zviri munjodzi (nozzles, zvindori zvekuisa chisimbiso, pombi dzejecha) wozvitsiva nenguva.
Chengetedza midziyo munzvimbo yakaoma uye yakachena.
Record
Rekodha nguva yekushandiswa kwejecha rejecha uye mamiriro ezvikamu zvakatsiviwa kuti zvifambise kugadzirisa.
Unyanzvi hwepamusoro uye mazano
Abrasive kusarudzwa: Sarudza yakakodzera mhando uye particle size yeabrasive inobva pane zvinyorwa zvebasa rekushanda (aluminium, simbi, composite zvinhu) uye inodiwa pamusoro roughness (Sa kukosha).
Nozzle kusarudzwa: Venturi mhando nozzles inoshanda zvakanyanya pane yakatwasuka magomba mhando iwoyo. Boron carbide/tungsten carbide nozzles ine hupenyu hwakareba kupfuura ma ceramic nozzles, asi zvakare inodhura.
Kushandirapamwe: Paunenge uchishanda munzvimbo dzakakura dzakavharirwa, zvinodikanwa kushanda vaviri vaviri uye kutarisana.
Kudzivirirwa kwezvakatipoteredza uye kudzokorodza: Kana mamiriro ezvinhu achibvumira, abrasive recycling uye kuronga system inofanirwa kugadzirwa kuti idzokorore mabrasives, kuderedza mutengo uye kuderedza huruva.
Pfupiso: Kushanda uye kwakachengeteka kushandisa matangi ekuputitsa pfuti kunotsamira pa "kunyatsogadzirira, kushanda kwakamisikidzwa uye kugadzirisa kwakasimba". Chete nekugara tichiisa pamberi pekuchengetedza uye kunyatsotevera maitiro ekushanda ejecha rejecha tangi tinogona kuve nechokwadi kufambira mberi kwakanaka kwebasa uye kuzadzisa inodiwa pamusoro pekurapa maitiro. Kune chaiwo mamodheru emidziyo, ndapota iva nechokwadi chekutarisa kune yayo yepamutemo mashandiro ekushandisa.
