Diki simbi pombi yomukati madziro sandblasting muchina

Diki simbi pombi yomukati madziro sandblasting muchina
Chengetedzo yemukati yemukati memadziro sandblasting maitiro ediki dhayamita simbi mapaipi (DN200 uye pazasi, kunyanya 30-200mm madiki madhayamita)
Kune madiki madiki mapaipi esimbi, nzvimbo yemukati yemadziro yakamanikana, zvakaoma kuisa musoro wepfuti nechepakati, uye kune matambudziko akadai sejecha blockage / kupotsa sanding / abrasive embedding. Iyo yese maitiro kubva pakusarudza yemukati madziro sandblasting muchina wemadhayamita madiki, parameter control, maitiro ekushanda, uye kudzivirira njodzi inoda kunyatsodzorwa:
1. Kusarudza uye pre-kugadzirira kwemukati memadziro ejecha muchina (core prerequisite, kusarudza midziyo isiriyo inotungamira mukukundikana)
Special midziyo inoenderana
Izvo zvinodiwa kuti usarudze yakatsaurirwa yemukati madziro sandblasting pfuti yediki madhayamita: sarudza inoenderana modhi maererano nedhayamita yepombi, seSY-50 ye35-75mm madhayamita, SY-100 ye50-200mm madhayamita.
Nozzle inofanira kugadzirwa netungsten simbi (kupfeka kuramba kunenge 3-5 nguva yeboron carbide), uye φ6-8mm diki dhayamita nozzle inoshandiswa pamapaipi madiki dhayamita kudzivirira musoro wepfuti kunamira mupombi.
Mhepo inogadziridza: vhoriyamu yekubuda kwemhepo compressor inofanira kuva Yakakura kudarika kana kuenzana ne6m³/min (pfuti imwe chete), uye matatu-matanho emafuta-anoparadzanisa mvura (sefa akarurama Isingasviki kana kuenzana ne0.1μm) inofanira kunge yakashongedzerwa - mvura mumhepo inovharika, pfuti inovharika, uye pfuti yakavharika inoita kuti pfuti ivhare musoro. iyo inonyanya kutadza kunobva kune diki dhayamita sandblasting.
Workpiece uye abrasive pre-kurapa
Pombi yesimbi pre-kuchenesa: chekutanga, bvisa nemaoko zvidimbu zvakakura zvewelding slag, oxide scale, nemarara kubva papombi kudzivirira kuvharira musoro wepfuti kana kukwenya madziro emukati panguva yejecha.
Abrasive control: sarudza 0.3-0.8mm fine-grained abrasive (mabhora esimbi/brown corundum anodiwa, uye zvidimbu zvihombe> 1mm zvinorambidzwa), abrasive inofanira kuomeswa nekusefa kubvisa huruva nemarara - nzvimbo yemukati yemapombi madiki anedhayamita ishoma, uye chidimbu chepfuti chichaita kuti pfuti iite muhombe. yakavharwa.
2. Kunyatso kudzora kwemukati madziro sandblasting machine process parameters
Kushanda kumanikidza: 0.5-0.6MPa (chaiyo dzvinyiriro pamuromo ndeye 0.35-0.5MPa).
Musoro wepfuti unofamba kumhanya: 0.5-1m/min (uyunifomu uchidzokera kumashure), nekukasira kunokonzeresa tambo-sejecha rapotsa, kunonoka kunokonzeresa jecha rakawandisa uye gomba.
Gun angle: kona iri pakati pemusoro wejecha uye rusvingo rwomukati rwepombi 15-30 dhigirii : yakanyanyisa kona ichaita kuti sanding yakawandisa kune rumwe rutivi, idiki yakanyanyisa inokonzera nzvimbo dzemapofu dzekuchenesa.
Simbi pombi kutenderera kumhanya (kutenderera kushanda): 10-20r/min, yakasanganiswa neaxial kufamba kwemusoro wepfuti, chengetedza 360 madhigirii eyunifomu kufukidzwa, dzivirira kutenderera-kunge akapotsa mabhendi ejecha.
3. Maitiro ekushanda emukati wemadziro sandblasting muchina
Kuchinja kutevedzana (kiyi yekudzivirira kuvharika kwejecha)
Tanga-kumusoro: tanga, dzikamisa mweya wakadzvanyirirwa → wozovhura vharuvhu yejecha (uniform kubuda kweabrasive);
Kudzima: chekutanga, vhara jecha vharuvhu → chengeta mweya wemhepo kwemasekonzi makumi matatu → wozomisa mhepo: nyatso buritsa zvakasara zvinoputika, huruva, nemarara mumusoro wepfuti, mumuromo nemupombi yemukati kudzivirira jecha rasara kuti risavharika nekuvharika.
Pfuti musoro kushanda zvinodiwa
Usambomira nepakati: musoro wepfuti unoramba uri panzvimbo imwe chete kweanopfuura masekonzi matatu zvinokonzeresa jecha rakawandisa uye kutetepa kwepombi-yakavharirwa nemadziro.
Post-kurapwa kunofanira kuitwa
Pakarepo mushure mekuputika kwejecha: ① shandisa 0.6MPa mweya wakadzvanywa kuridza pombi zvakazara; ② shandisa endoscope kuti utarise makona epombi kuti uone kuti hapana jecha rasara usati waendesa kune yekupfekedza.
Four. Kugamuchirwa kwehutano uye kudzivirira dambudziko rinowanzoitika
Kubvuma mitemo
Hutsanana: kusvika paSa2.5 level, hapana chinooneka oxide sikero, ngura, kana welding slag pamadziro emukati, simbi yakafanana inobuda pachena, hapana tambo{1}}sejecha rapotsa;
Kukasharara kwepamusoro: Ra25-50μm, hapana kudzvanya, hapana gomba, hapana kukoromoka kwemadziro matete;
Utsanana: hapana yakasara abrasive, guruva mupombi, haikanganisi kunotevera kupfeka kana kufambisa kwepakati.
Kudzivirira dambudziko rakajairika: nyaya dzinowanzoitika
Pfuti yakavharwa: iyo midzi inokonzeresa yakanyorova abrasive / mahombe particles / isiriyo yekudzima kutevedzana, nyatso tevera abrasive kuomesa uye kudzima tsika kudzivirira 99% yematambudziko;
Kushaikwa sanding: too fast gun musoro kufamba panguva yekushanda;
Abrasive Embedding: Yakawandisa kudzvanywa uye oversized abrasive particles. Papombi-dzakakomberedzwa nemadziro, dzvinyiriro inodzika kusvika pa0.4-0.5 MPa, uye twumabrasives hahufanire kudarika 0.8mm.
Internal Wall Scratches: Iyo muromo inonamatira kumadziro epombi, uye kune zvinhu zvekunze mukati mepombi. Kunyatsogadzirisa{1}}kunodiwa kuti uchenese pombi uye kuona kuti muromo wakamira pakati.
V. Kuchengetedzwa uye Zvakatipoteredza Zvinodiwa Zvinodiwa
Kudzivirirwa Kwevashandi: Guruva kubva kudiki-paipi yejecha jecha rinokwanisa kuungana mukati mepombi. Vashandi vanofanirwa kupfeka zvakanaka zvinofemesa mweya uye vanorambidzwa zvachose kushandisa masiki akajairwa; kumira zvakananga pamberi pepombi kuvhurwa kunorambidzwa kudzivirira jecha particles kudzoka uye kukuvadza vanhu.
Kudzora kwezvakatipoteredza: Pombi yemukati yekufefetera uye yekubvisa huruva system inofanirwa kunge yakashongedzerwa (ine mhepo vhoriyamu yeGreater than kana yakaenzana ne5000 m³/h). Hose yekubvisa guruva inofanira kubatanidzwa kune kuguma kwejecha, uye imwe mugumo inofanira kuiswa chisimbiso kudzivirira kusina kurongeka kweguruva; abrasive particles anofanirwa kuunganidzwa nechepakati uye haafanire kuraswa zvisina tsarukano.
Equipment Safety: The pressure gauge ne safety valve ye air compressor inofanira kucheneswa mwedzi nemwedzi, uye hose yejecha rinofanirwa kuongororwa kuti harishandi here nguva nenguva kudzivirira kuputika kukuru nekukuvara kwe-.
