Ke sethunya se tšoanelehang feela se ka kenang mochining oa ho phatloha bakeng sa ho sebelisoa hape, ho netefatsa botsitso ba matla a ejection le phello e hlabang.
Hopper ea polokelo le valve ea taolo ea phallo: Boloka sethunya se hloekisitsoeng 'me u laole ka nepo ho phalla ha sethunya se kenang ka li-valve tsa heke tsa moea kapa tsa motlakase.
5. Tsamaiso ea ho tlosa lerōle
Phaephe ea ho bokella lerōle: E hokahanya phaposi ea ho qhomisa lerōle.
Ho bokella lerōle: Hangata, ho sebelisoa mochini o bokellang lerole la pulse-jet cartridge, o sebelisetsoang ho bokella le ho sefa lerole le hlahisoang nakong ea ts'ebetso, ho boloka ponahalo ea ka tlung, ho sireletsa lisebelisoa, le ho fihlela litlhoko tsa ts'ireletso ea tikoloho.
6. Mokhoa oa ho laola motlakase
PLC (Programmable Logic Controller) : Boko ba thepa eohle ea phekolo e hlabang holim'a metsi, e laolang ho qaleha le ho emisa ha li-motor tsohle, likarolo tsa pneumatic, lihlooho tse lahlelang, joalo-joalo.
HMI (Human-Machine Interface Touch Screen) : Ka eona, basebetsi ba kenya le ho seta liparamente tsa ts'ebetso tse joalo ka lebelo la roll, nako ea ho phatloha ha sethunya, matla a hlooho a thuntseng, le ho beha leihlo boemo ba ts'ebetso ea sesebelisoa.
Tlhokomelo ea ts'ebetso: Sistimi e tsoetseng pele e tla kopanya mokhoa oa ho lekanya likotoana tsa Almen ho lekanya, ho netefatsa le ho rekota botebo ba ts'ebetso e 'ngoe le e' ngoe, ho netefatsa ho pheta-pheta ha ts'ebetso le ts'ebetso ea boleng.
Iii. Tšebeliso ea 'Maraka ea Lisebelisoa tsa Phekolo ea Roll Surface Roughening
Mmaraka oa tšebeliso ea mochini o qhomisang li-roll roughening shot o tsepame haholo, hoo e batlang e shebane le indasteri e phahameng-ea ho roala lilakane tsa tšepe.
1. 'Maraka oa kopo ea mantlha
Mohala oa tlhahiso ea poleiti e batang{{0}e rolisitsoeng: Ena ke karolo ea mantlha ea mochini o qhomisang lithunya. Haholo-holo tlhahiso:
Phanele ea Likoloi: E na le litlhoko tse phahameng haholo bakeng sa bokaholimo, e hloka ho ba mahoashe ka mokhoa o ts'oanang le ho teteana ha tlhoro ho netefatsa boleng ba ponahalo le bofokoli ba pente kamora ho theha setempe. Ena ke ts'ebeliso e tsoetseng pele ka ho fetisisa.
Maboto a-a boleng bo phahameng ba Home Appliance: joalo ka liboto tsa ka ntle tsa lihatsetsi, metjhini e hlatsoang liaparo le lionto tsa microwave, tse hlokang mamati a matle le ponahalo ea matte.
Tinplate (tinplate) le chrome-plated plate (TFS) : Li sebelisoa ka har'a-ho etsa liindasteri tse kang makotikoti a lijo le makotikoti a lino, 'me li hloka hore ho behoe litlolo hantle le ho sebetsa hantle.
Liphanele tsa mekhabiso ea meralo: joalo ka liphanele tsa likoloi tsa lifti, liphanele tsa mekhabiso ea kahare, jj.
2. Papiso ea Alternative Technologies for Roll Roughening Shot machines:
VS Pickling: Tloaelo ea khale ea pickling roughening (e kang koporo-plated ball roughening) e felisitsoe haholo ke ho phatloha ho hoholo ka lebaka la mathata a tikoloho (pheko ea asiti ea litšila) le ho se laolehe hantle ha boleng bo holimo.
VS Laser Texturing: Ho ngola ka Laser ho ka hlahisa morphologies e tloaelehileng le e laolehang ka ts'ebetso e ntle, empa matsete a lisebelisoa le litšenyehelo tsa ts'ebetso li holimo haholo. Litheko tse phahameng haholo, 'me li bitsa chelete e ngata, li hapile 'maraka o moholo oa 'maraka, haholo-holo bohareng ba{-ho ea{3}}limmaraka tse holimo.
3. Lintlha tse tsamaisang 'maraka tsa mochini o qhomisang ho phatloha:
Ntlafatso ea liindasteri tsa makoloi le lisebelisoa tsa lapeng: Litlhoko tsa Bareki tsa boleng ba ponahalo ea likoloi le lisebelisoa tsa lapeng li ntse li phahama, e leng se etsang hore bahlahisi ba thepa ba sebelise mekhoa e tsoetseng pele ea ho senya.
Melaoana ea ts'ireletso ea tikoloho e ntse e thatafala le ho feta: Melao ea ts'ireletso ea tikoloho e felisitse mekhoa ea khale ea ho silafatsa, e bula tsela bakeng sa mahlale a tala a ho thunya 'marakeng.
Litlhoko tsa boleng ba sehlahisoa le botsitso: Indasteri ea sejoale-joale ea tlhahiso e hloka botsitso bo phahameng haholo ba sehlahisoa le ho latella morao. Mechini e otlang ka ho feletseng le e laoloang ke linomoro ka ho feletseng e finyella tlhokahalo ena.
Kakaretso
The roll roughening shot blasting machine ke theknoloji-sesebelisoa se khethehileng se matla sa ho alafa bokaholimo.
Mabapi le sebopeho: E kopanya mechine e nepahetseng, boenjiniere ba thepa, matla a mokelikeli le theknoloji ea ho laola ka mokhoa o itekanetseng, ho netefatsa hore li-microscopic morphologies tse finyellang litekanyetso tse tiileng li ka sebelisoa khafetsa le ho lateloa holim'a meqolo.
Ha e sebelisoa: Thepa ea ho phekola ka holim'a metsi e batla e le sesebelisoa se tloaelehileng bakeng sa ho etsa-litšepe tse rolotsoeng tse batang haholo-(haholo-holo tsa likoloi), 'me tlhoko ea eona ea 'maraka e amana haholo le katleho ea liindasteri tse kang likoloi le lisebelisoa tsa lapeng. Ka ts'ebetso ea eona e ikhethang ea litšenyehelo le melemo ea ts'ireletso ea tikoloho, e fetohile e 'ngoe ea lisebelisoa tsa bohlokoa indastering ea sejoale-joale ea tšepe.
