Umbhobho omncinci wentsimbi yangaphakathi yodonga lwesanti umatshini

Umbhobho omncinci wentsimbi yangaphakathi yodonga lwesanti umatshini
Izilumkiso ezingundoqo zenkqubo yokuqhunyiswa kwesanti eludongeni lwemibhobho yentsimbi edayamitha encinci (i-DN200 nangaphantsi, ngakumbi i-30-200mm iidamitha ezincinci)
Kwimibhobho yentsimbi enobubanzi obuncinci, indawo yodonga lwangaphakathi imxinwa, kunzima ukubeka intloko yompu embindini, kwaye kukho iingxaki ezifana nokuvala isanti / ukuphoswa kwesanti / ukufakwa kwe-abrasive. Yonke inkqubo ekukhetheni umatshini wesanti wodonga lwangaphakathi kwiidayamitha ezincinci, ulawulo lweparamitha, imigaqo yokusebenza, kunye nokuphepha umngcipheko kufuneka ilawulwe ngokungqongqo:
1. Ukukhetha kunye{1}}kwangaphambili nokulungiswa komatshini wesanti wodonga lwangaphakathi (imfuneko engundoqo, ukukhetha izixhobo ezingalunganga kuya kukhokelela ekusilela)
Ukuthelekisa izixhobo ezikhethekileyo
Kuyimfuneko ukuba ukhethe umpu wangaphakathi ozinikeleyo we-sandblasting gun kwiidamitha ezincinci: khetha imodeli ehambelanayo ngokobubanzi bombhobho, njenge-SY-50 ye-35-75mm ububanzi, i-SY-100 ye-50-200mm ububanzi.
Umbhobho kufuneka wenziwe ngentsimbi ye-tungsten (ukumelana nokunxiba kuphindwe ka-3-5 kune-boron carbide), kwaye umbhobho omncinci we-φ6-8mm wedayamitha encinci usetyenziselwa imibhobho edayamitha emincinci ukunqanda ukuba intloko yompu ibambeke kumbhobho.
Uqwalaselo lomthombo womoya: umthamo wokukhupha wecompressor womoya kufuneka ube Mkhulu okanye ulingane no-6m³/min (umpu omnye), kunye nenqanaba lesithathu-i-oyile yeqonga{2}} isahluli samanzi (ukuchaneka kwesihluzi Ngaphantsi okanye silingane no-0.1μm) kufuneka sixhotyiswe - ngamanzi kunye nompu oxinzelelweyo obangela ukuba umoya uxinzelelwe kwaye ubambe umoya oxinanisiweyo. owona mthombo uxhaphakileyo wokuqhushumba kwesanti edayamitha encinci.
Iworkpiece kunye ne-abrasive pre{0}}yonyango
Umbhobho wentsimbi kwangaphambili-ukucoca: okokuqala, susa ngesandla amaqhekeza amakhulu e-welding slag, isikali se-oxide, kunye nobutyobo kumbhobho ukunqanda ukuvalela intloko yompu okanye ukukrwela udonga lwangaphakathi ngexesha lokuqhushumba kwesanti.
Ulawulo lwe-abrasive: khetha i-0.3-i-0.8mm ecolekileyo{3}}i-grained abrasive (iibhola zentsimbi / i-brown corundum iyakhethwa, kwaye amasuntswana amakhulu> 1mm awavumelekanga), i-abrasive kufuneka yomiswe kwaye ihluzwe ukuze kususwe uthuli kunye nobutyobo - isithuba sangaphakathi semibhobho encinci yedayamitha sinqunyelwe, kwaye i-particle enkulu iya kuba nentloko okanye i-100 yentloko enkulu. ivaliwe.
2. Ulawulo oluchanekileyo lweparameters zenkqubo yomatshini wesanti yangaphakathi
Uxinzelelo lokusebenza: 0.5-0.6MPa (uxinzelelo lwangempela kwi-nozzle yi-0.35-0.5MPa).
Isantya esishukumayo sentloko yompu: 0.5-1m/min (iyunifomu yokubuyela umva intshukumo), ngokukhawuleza kakhulu kuya kubangela ukuphoswa kwesanti, ukucotha kakhulu kuya kubangela ukubamba kwesanti kunye nokugqobhoza okukhulu kwendawo.
I-angle ye-gun: i-angle phakathi kwentloko ye-sanding kunye nodonga lwangaphakathi lombhobho yi-15-30℃: i-angle enkulu kakhulu iya kubangela ukugqithiswa kwe-sanding kwelinye icala, i-angle encinci iya kubangela iindawo ezingaboniyo zokucoca.
Isantya sokujikeleza kombhobho wentsimbi (ukusebenza okujikelezayo): 10-20r/min, kudityaniswe nentshukumo ye-axial yentloko yompu, qinisekisa ukugqunywa kweyunifomu ye-360 degree, ugweme i-spiral-like missed bands sanding.
3. Imilinganiselo yokusebenza yomatshini wokuqhunyiswa kwesanti eludongeni lwangaphakathi
Ukutshintsha ulandelelwano (isitshixo sokuthintela ukuvaleka kwesanti)
Qalisa-phezulu: kuqala, zinzisa uxinzelelo lomoya ocinezelweyo → emva koko uvule ivalve yesanti (imveliso efanayo yeabrasive);
Cima: okokuqala, vala ivalve yesanti → gcina umoya imizuzwana engama-30 → uze umise umoya: uvuthulule ngokucokisekileyo intsalela yerhasi, uthuli, nobutyobo obusentloko yompu, emlonyeni, kunye nombhobho ongaphakathi ukunqanda intlabathi eshiyekileyo ekuvalekeni nasekuvalekeni.
Iimfuno zokusebenza kwentloko yompu
Sukumisa embindini: intloko yompu eshiyeke kwindawo enye ngaphezulu kwemizuzwana emi-3 iya kubangela isanti egqithisileyo yendawo kunye nokugqobhozwa kombhobho obhityileyo-.
Ngeposi-unyango kufuneka lwenziwe
Ngokukhawuleza emva kokuqhunyiswa kwesanti: ① sebenzisa i-0.6MPa yomoya oxinanisiweyo ukuvuthela ngokupheleleyo umbhobho; ② sebenzisa i-endoscope ukuhlola iikona zemibhobho ukuqinisekisa ukuba akukho santi eshiyekileyo ngaphambi kokuba idluliselwe kwinkqubo yokwaleka.
Isine. Ukwamkelwa komgangatho kunye nokuphepha ingxaki eqhelekileyo
Imigangatho yokwamkelwa
Ukucoceka: fikelela kwinqanaba le-Sa2.5, akukho sikali sibonakalayo se-oxide, umhlwa, okanye i-slag ye-welding kudonga lwangaphakathi, ukuvezwa kombala wentsimbi efanayo, akukho mcu-njengesanti ephosiweyo;
Uburhabaxa bomphezulu: iRa25-50μm, akukho kufakelwa ibrasive, akukho pitting, akukho deformation ebhityileyo;
Ukucoceka: akukho i-abrasive eseleyo, uthuli kumbhobho, ayichaphazeli i-coating elandelayo okanye ukuthutha okuphakathi.
Ukuphepha ingxaki eqhelekileyo: imiba eyenzeka rhoqo
Umpu ovaliweyo: ingcambu ingcambu i-abrasive abrasive / amasuntswana amakhulu / ukulandelelana okungachanekanga kokuvala, landela ngokungqongqo ukomisa okukrakra kunye nemimiselo yokuvala ukuphepha i-99% yeengxaki;
Ukuphoswa kwesanti: intshukumo yentloko yompu ekhawuleza kakhulu ngexesha lokusebenza;
I-Abrasive Embedding: Uxinzelelo olugqithisileyo kunye namasuntswana abrasive oversized. Kwimibhobho -ebhityileyo, uxinzelelo lwehla ukuya kwi-0.4-0.5 MPa, kwaye amasuntswana abrasive akufanele adlule kwi-0.8mm.
Imikrwelo yodonga lwangaphakathi: Umbhobho unamathela eludongeni lombhobho, kwaye kukho izinto zangaphandle ngaphakathi kumbhobho. Unyango lwangaphambili{1} olucokisekileyo luyimfuneko ukuze ucoce umbhobho ngocoselelo kwaye uqinisekise ukuba umlomo uphakathi.
V. IiMfuno eziMnyanzelo zoKhuseleko kunye nokuSingqongileyo
Ukhuseleko lwaBasebenzi: Uthuli olusuka kumbhobho omncinci{0}}wokuqhushumba kwesanti yombhobho wobubanzi kungenzeka kakhulu ukuba buqokelele ngaphakathi kumbhobho. Abaqhubi kufuneka banxibe iziphefumli zoxinzelelo olulungileyo kwaye bathintelwe ngokungqongqo ekusebenziseni iimaski eziqhelekileyo; ukuma ngqo phambi kokuvulwa kombhobho akuvumelekanga ukunqanda amasuntswana esanti aphinde aphinde enzekalisa abantu.
Ulawulo lokusiNgqongileyo: Umbhobho wokungena komoya wangaphakathi kunye nenkqubo yokususa uthuli kufuneka ixhotyiswe (ngomthamo womoya ongaphezulu okanye olingana nama-5000 m³/h). I-hose yokususa uthuli kufuneka idibaniswe ekupheleni kwe-sandblasting, kwaye enye isiphelo kufuneka itywinwe ukukhusela ukukhutshwa kothuli olungacwangciswanga; amasuntswana abrasive kufuneka aqokelelwe embindini kwaye kufuneka angalahlwa ngokungacwangciswanga.
Ukhuseleko lweZixhobo: Igeyiji yoxinzelelo kunye nevalve yokhuseleko yesicinezeli somoya kufuneka ilinganiswe ngenyanga, kwaye umbhobho wokuqhumisa isanti kufuneka uhlolwe ukuba ungagugi rhoqo ukunqanda ukugqabhuka koxinzelelo oluphezulu{0}nokwenzakala.
