Amaphayiphu wokushaya

Amaphayiphu wokushaya do-it-yourself - inqubo elula, inqobo nje uma i-auto-amateur ngaphambili yayinolwazi ekwenzeni umsebenzi wokulungisa. Ukuze ugoqe izihlalo zamavalvu, uzodinga inani lamathuluzi nezinto zokwakha, okuhlanganisa ukunamathiswa kwe-valve, idivaysi yokuqaqa ama-valve, i-drill (isikulufi), uphalafini, isiphethu esidlula emgodini wesihlalo se-valve ububanzi. Ngokuya kwesikhathi, ukugaya ama-valve enjini yomlilo yangaphakathi kuyinqubo ebiza kakhulu, ngoba ukuze uyiqedele, kuyadingeka ukudiliza ikhanda le-cylinder.

Yini i-lapping futhi kungani idingeka

I-valve lapping iyinqubo eqinisekisa ukulingana okuphelele kwamavalvu okungenisa nawokukhipha umoya kumasilinda enjini evuthayo angaphakathi ezihlalweni zawo (isihlalo). Ngokuvamile, ukugaya kwenziwa lapho kushintsha ama-valve amasha, noma ngemva kokulungiswa kwenjini yomlilo yangaphakathi. Ngokufanelekile, ama-valve ane-lapped ahlinzeka ngokuqina okuphezulu kusilinda (igumbi lomlilo). Lokhu, futhi, kuqinisekisa izinga eliphezulu lokucindezela, ukusebenza kahle kwemoto, ukusebenza kwayo okujwayelekile kanye nezici zobuchwepheshe.

Ngamanye amazwi, uma ungagayi ngamavalvu amasha, khona-ke ingxenye yamandla amagesi ashile izolahleka ngokungenakulungiseka esikhundleni sokuhlinzeka amandla afanele enjini evuthayo yangaphakathi. Ngesikhathi esifanayo, ukusetshenziswa kukaphethiloli kuzokwanda, futhi amandla enjini azokwehla nakanjani. Ezinye izimoto zesimanje zifakwe i-automatic valve control system. Imane igaye i-valve, ngakho-ke asikho isidingo sokugaya ngesandla.

Okudingekayo ekugayeni

Inqubo ye-lapping yenziwa ngekhanda le-cylinder lisusiwe. Ngakho-ke, ngaphezu kwamathuluzi okugaya ama-valve, umnikazi wemoto uzodinga futhi ithuluzi lokudiliza ikhanda le-cylinder. ngokuvamile, lezi izikhiye ezijwayelekile zokukhiya, ama-screwdrivers, ama-rags. Kodwa-ke, kuyafiseleka futhi ukuba ne-torque wrench, ezodingeka esigabeni sokuhlanganisa kabusha ikhanda endaweni. isidingo salo sivela, njengoba amabhawodi okulungisa abambe ikhanda esihlalweni sawo kufanele aqiniswe ngomzuzwana othile, ongaqinisekiswa kuphela ngesikrufu se-torque. Kuye ngokuthi iyiphi indlela yokufaka ama-valve azokhethwa - manual noma mechanized (mayelana nabo kamuva nje), isethi yamathuluzi omsebenzi nayo ihlukile.

okokufaka ama-valve umnikazi wemoto azowadinga:

• Isibambi se-valve esenziwa ngesandla. Ezitolo zezimoto noma ezitolo zokulungisa izimoto, imikhiqizo enjalo esenziwe ngomumo iyathengiswa. Uma ngesizathu esithile ungafuni noma awukwazi ukuthenga umnikazi onjalo, khona-ke ungayenza ngokwakho. Indlela yokuyikhiqiza kabusha ichazwe esigabeni esilandelayo. Isibambi se-valve semanuwali sisetshenziswa lapho udweba ama-valve ngesandla.
• I-Valve Lapping Namathisela. Ezimweni eziningi, abanikazi bezimoto bathenga ama-compounds esenziwe ngomumo, njengoba okwamanje kunenqwaba yalezi zimali ezinkampanini zezimoto, kufaka phakathi amanani ahlukene. Ezimweni ezimbi kakhulu, ungakwazi ukukhiqiza ukwakheka okufanayo ngokwakho kusuka kuma-chips abrasive.
• I-drill noma i-screwdriver nethuba lokuhlehla (ngokugaya ngomshini). ngokuvamile, ukugaya kwenziwa kuzo zombili izinkomba zokuzungezisa, ngakho-ke i-drill (isikulufa) kufanele ijikeleze kokubili ohlangothini olulodwa nakwesinye. ungasebenzisa futhi umshini wokubhola ngesandla, wona ngokwawo ongazungeza ohlangothini olulodwa nakwelinye.

• Ipayipi nentwasahlobo. Lawa madivaysi ayadingeka ukuze kugqitshwe ngomshini. Intwasahlobo kufanele ibe nokuqina okuphansi, futhi ububanzi bungamamilimitha amabili kuya kwamathathu mkhulu kunobubanzi besiqu se-valve. Ngokufanayo, i-hose, ukuze ibekwe phezu kwenduku. ungasebenzisa futhi i-clamp encane ukuyivikela. enye induku yensimbi emfushane nayo iyadingeka ngobubanzi obufana nenduku ye-piston, ukuze ingene kahle epayipini lerabha.
• Amafutha. Isetshenziswa njengesicoci bese kuthi ngemuva kwalokho kubhekwe ikhwalithi ye-lapping eyenziwe.
• "Sharoshka". Leli ithuluzi elikhethekile elenzelwe ukususa insimbi eyonakele esihlalweni se-valve. Imishini enjalo idayiswa isilungele ukwenziwa ezindaweni ezidayisa izimoto. Njengamanje, ezindaweni ezithengisa izimoto ungathola le ngxenye cishe yanoma iyiphi injini evuthayo yangaphakathi (ikakhulukazi ezimotweni ezivamile).
• Izindwangu. Kamuva, ngosizo lwayo, kuyodingeka ukusula izindawo eziphathwayo ezomile (ngasikhathi sinye izandla).
• I-solvent. Kudingeka ukuhlanza izindawo zokusebenza.
• I-Scotch tape. Kuyingxenye edingekayo lapho kwenziwa enye yezindlela zokuhlanza ezenziwe ngomshini.

Ithuluzi le-Valve Lapping

Uma umnikazi wemoto engenalo ithuba / isifiso sokuthenga idivayisi yefekthri yokugaya ama-valve ngezandla zakhe (ngesandla), idivayisi efanayo ingakhiqizwa ngokuzimela ngokusebenzisa izindlela ezithuthukisiwe. Ukuze wenze lokhu uzodinga:

• Ishubhu lensimbi elinesikhala ngaphakathi. Ubude bayo kufanele bube ngu-10 ... 20 cm, futhi ububanzi bomgodi ongaphakathi we-tube kufanele bube ngu-2 ... 3 mm mkhulu kunobubanzi besiqu se-valve injini evuthayo yangaphakathi.
• I-drill kagesi (noma i-screwdriver) kanye nensimbi yokugaya enobubanzi obungu-8,5 mm.
• Xhumana noma ukushisela igesi.
• I-nati nebhawudi enobubanzi obungu-8 mm.

I-algorithm yokukhiqiza idivayisi yokugaya i-valve izoba kanje:

• Ukusebenzisa i-drill ebangeni elingama-7 ... 10 mm ukusuka kwelinye lamaphethelo, udinga ukubhoboza imbobo yobubanzi obuboniswe ngenhla.
• Usebenzisa i-welding, udinga ukushisela inati ngqo phezu komgodi oboshiwe. Kulokhu, udinga ukusebenza ngokucophelela ukuze ungalimazi izintambo ku-nut.
• Khipha ibhawudi enathini ukuze umkhawulo walo ufinyelele endaweni engaphakathi yodonga lweshubhu olubhekene nembobo.
• Njengesibambo seshubhu, ungakwazi ukugoba ingxenye ephambene yepayipi nge-engeli engakwesokudla, noma ungakwazi ukushisela ucezu olulodwa lwepayipi nanoma iyiphi enye ingxenye yensimbi efana nokuma (iqonde).
• Khumula ibhawodi emuva, bese ufaka isiqu se-valve eshubhuni, bese usebenzisa ibhawodi ukuyiqinisa ngokuqinile ngesikrufu.

Njengamanje, idivayisi efanayo eyenziwe efekthri ingatholakala ezitolo eziningi ze-inthanethi. Kodwa-ke, inkinga iwukuthi ngokusobala zibiza ngokweqile. Kodwa uma umthandi wemoto engafuni ukwenza inqubo yokukhiqiza yedwa, ungathenga ngokuphelele idivayisi yokugaya ama-valve.

Izindlela zokuvala i-valve

Empeleni kunezindlela ezimbili zokugaya ama-valve - okwenziwa ngesandla nangomshini. Kodwa-ke, ukugqobhoza ngesandla kuyinqubo ekhandlayo futhi edla isikhathi. Ngakho-ke, kungcono ukusebenzisa indlela ebizwa ngokuthi i-mechanized, usebenzisa i-drill noma i-screwdriver. Nokho, sizohlaziya indlela eyodwa nenye ngokulandelana kwayo.

Kungakhathaliseki ukuthi iyiphi indlela yokudonsa ekhethiwe, isinyathelo sokuqala ukuqaqa ama-valve kusukela ekhanda le-cylinder (kufanele futhi ihlakazwe kusengaphambili). Ukuze ususe ama-valve emabhuthini omhlahlandlela wekhanda le-cylinder, udinga ukususa iziphethu ze-valve. Ukuze wenze lokhu, sebenzisa idivayisi ekhethekile, bese ususa "ama-crackers" emapuletini eziphethu.

Indlela yokwenza i-manual

Ukuze ugaye ama-valve enjini yomlilo yangaphakathi yemoto, udinga ukulandela i-algorithm engezansi:

• Ngemuva kokudiliza i-valve, udinga ukuyihlanza kahle kumadiphozithi ekhabhoni. Ukuze wenze lokhu, kungcono ukusebenzisa ama-ejenti okuhlanza akhethekile, kanye ne-abrasive surface ukuze kususwe ngokuphelele i-plaque, amafutha, nokungcola ebusweni.
• Faka ungqimba oluncane oluqhubekayo lwe-lapping paste ebusweni be-valve (unamathisele ohlaza okwesibhakabhaka kusetshenziswa kuqala, bese kuba unamathisele ocolile).

• Uma kusetshenziswe idivayisi yokuzenzela echazwe ngenhla, khona-ke kuyadingeka ukufaka i-valve esihlalweni sayo, uphendule ikhanda le-cylinder, bese ubeka isibambi ku-valve esemkhonweni we-valve futhi ugcotshwe nge-lapping paste. khona-ke udinga ukuqinisa i-bolt ukuze ulungise i-valve epayipini ngokuqinile ngangokunokwenzeka.
• Khona-ke udinga ukuzungezisa idivayisi yokudonsa kanye ne-valve ngokushintshana kuzo zombili izinkomba ngokujika kwesigamu (cishe ± 25 °). Ngemuva komzuzu owodwa noma emibili, udinga ukuvula ivalve ngo-90 ° ngokwewashi noma ngokuphambene newashi, phinda ukunyakaza kokuzungeza emuva naphambili. I-valve kufanele ifakwe i-lapped, ngezikhathi ezithile uyicindezele esihlalweni, bese uyikhulula, phinda inqubo ngokujikeleza.
• Kudingeka ukuthi kuxhunywe ama-valve mathupha yenza kuze kube yilapho kuvela ibhande elimpunga ngisho ne-monochromatic ku-chamfer. Ububanzi bayo bungaba ngu-1,75 ... 2,32 mm wama-valve okungenisa, kanye no-1,44 ... 1,54 mm wama-valve okukhipha umoya. Ngemuva kwe-lapping, ibhande le-matte grey lobukhulu obufanele akufanele livele kuphela ku-valve ngokwayo, kodwa futhi esihlalweni sayo.
• Olunye uphawu umuntu angahlulela ngalo ngokungaqondile ukuthi ukugqigqa kungaqedwa wushintsho emsindweni wenqubo. Uma ekuqaleni kokuyihlikihla izoba "insimbi" futhi inomsindo, khona-ke ngasekupheleni komsindo uzophazamiseka kakhulu. Okusho ukuthi, lapho insimbi ingaxubeki ensimbi, kodwa insimbi endaweni ye-matte. Imvamisa, inqubo ye-lapping ithatha imizuzu emi-5-10 (kuya ngesimo esithile kanye nesimo somshini we-valve).
• Ngokujwayelekile, i-lapping yenziwa kusetshenziswa unamathisele osayizi abahlukahlukene bokusanhlamvu. Okokuqala, kusetshenziswa i-coarse-grained paste, bese i-fine-grained. I-algorithm yokuzisebenzisa iyafana. Kodwa-ke, ukunamathisela kwesibili kungasetshenziswa kuphela ngemva kokuba inhlama yokuqala ifakwe kahle futhi yaqina.
• Ngemuva kokugcoba, kuyadingeka ukusula kahle i-valve nesihlalo sayo nge-rag ehlanzekile, futhi ungakwazi futhi ukugeza ubuso be-valve ukuze ususe izinsalela zokunamathisela kwe-lapping ebusweni bayo.
• Hlola ikhwalithi ye-lapping ngokubheka ukugxila kwendawo ye-valve disc kanye nesihlalo sayo. Ukuze wenze lokhu, sebenzisa ungqimba oluncane lwe-graphite ku-chamfer yekhanda le-valve ngepensela. khona-ke i-valve ephawuliwe kufanele ifakwe emkhonweni womhlahlandlela, icindezelwe kancane esihlalweni, bese iphenduka. Ngokusho kwemikhondo ye-graphite etholiwe, umuntu angahlulela ukugxila kwendawo ye-valve nesihlalo sayo. Uma i-lapping ilungile, khona-ke kusukela ekuphendukeni okukodwa kwe-valve wonke amadeshi asetshenzisiwe azosulwa. Uma lokhu kungenzeki, ukugaya kufanele kuphindwe kuze kube yilapho isimo esishiwo sifinyelelwa. Nokho, ukuhlola okugcwele kwenziwa ngenye indlela, echazwe ngezansi.
• Lapho sekuqediwe ukugqitshwa kwama-valve, zonke izindawo zokusebenza zezingxenye zigezwa ngophalafini ukuze kukhishwe unamathisele osele nokungcola. Isiqu se-valve kanye nomkhono kugcotshwe ngamafutha enjini. ngokuqhubekayo, ama-valve afakwe ezihlalweni zawo ekhanda le-cylinder.

Lapho wenza ama-valve e-lapping, udinga ukususa lezi zinhlobo ezilandelayo zamaphutha:

• I-carbon deposits kuma-chamfers engazange iholele ekuguqulweni kwe-chamfer (valve).
• I-carbon deposits kuma-chamfers, okuholela ekuguquguqukeni. okungukuthi, kwavela indawo enezitebhisi ebusweni bazo obuyindilinga, futhi i-chamfer ngokwayo yaba yindilinga.

Sicela uqaphele ukuthi uma esimweni sokuqala i-valve ingamane igaywe, khona-ke okwesibili kuyadingeka ukwenza i-groove yayo. Kwezinye izimo, i-lapping yenziwa ngezigaba eziningana. Isibonelo, i-rough lapping yenziwa kuze kube yilapho wonke amagobolondo nemihuzuko ekhishwa ebusweni bomsebenzi wokusebenza. Ngokuvamile, ukunamathisela okunamazinga ahlukene e-grit kusetshenziselwa ukugoqa. I-abrasive emahhadla yakhelwe ukususa umonakalo omkhulu, kanti inhlawulo ingeyokuqeda. Ngakho-ke, uma i-abrasive isetshenziswa kahle, kungcono ukubopha ama-valve. Ngokuvamile okunamathiselwe kunezinombolo. Isibonelo, 1 - ukuqeda, 2 - rough. Akuthandeki ukuthi unamathisele okugwazayo ungene kwezinye izakhi zomshini wevalvu. Uma efikile - geza ngophalafini.

Ama-valve e-Lapping nge-drill

Ama-valve e-Lapping nge-drill yiyona ndlela engcono kakhulu, ongonga ngayo isikhathi nomzamo. Umgomo wayo ufana nokugaya ngesandla. I-algorithm yokusetshenziswa kwayo imi kanje:

• Thatha induku yensimbi elungisiwe bese ubeka ipayipi yerabha yobubanzi obufanele kuyo. Ukuze ulungise kangcono, ungasebenzisa i-clamp yobubanzi obufanele.
• Lungisa induku yensimbi eshiwo ngepayipi lerabha elinamathiselwe ku-chuck ye-drill kagesi (noma i-screwdriver).
• Thatha i-valve ubeke isiphethu esiqwini sayo, bese usifaka esihlalweni sayo.
• iphushela kancane i-valve ekhanda lesilinda, faka inani elincane lokunamathisela okugobhozayo ku-chamfer yayo eduze komjikelezo wepuleti layo.
• Faka isiqu se-valve epayipini lerabha. Uma kunesidingo, sebenzisa futhi i-clamp ye-diameter efanele ukuze uqinise kangcono.
• Shaya ngesivinini esiphansi qala ukuqhwanda i-valve esihlalweni sayo. Kulesi simo, udinga ukuyihambisa emuva naphambili, lapho, empeleni, intwasahlobo efakiwe izosiza. Ngemuva kwemizuzwana embalwa yokuzungeza ohlangothini olulodwa, udinga ukushintsha i-drill ukuze uhlehlise, futhi uyijikelezise ngakolunye uhlangothi.
• Yenza inqubo ngendlela efanayo, kuze kube yilapho kuvela ibhande le-matte emzimbeni we-valve.
• Lapho usuqedile ukugoqa, sula ngokucophelela i-valve ezinsalela zokunamathisela, okungcono kakhulu nge-solvent. Ngaphezu kwalokho, kuyadingeka ukususa ukunamathisela hhayi kuphela ku-chamfer ye-valve, kodwa futhi esihlalweni sayo.

Ukufaka ama-valve amasha

Kuphinde kube nokugedla okukodwa kwamavalvu amasha ekhanda lesilinda. I-algorithm yokusetshenziswa kwayo imi kanje:

• Ukusebenzisa i-rag efakwe ku-solvent, susa ukungcola futhi ubeke kuma-chamfers awo wonke ama-valve amasha, kanye nasezihlalweni zawo (izihlalo). Kubalulekile ukuthi izindawo zabo ezingaphezulu zihlanzekile.
• Thatha ucezu lwetheyiphu enamahlangothi amabili bese ulinamathisela epuletini le-valve evalekile (esikhundleni se-tape enamacala amabili, ungathatha ejwayelekile, kodwa qala wenze indandatho kuyo bese uyikhama ibe yisimo esiyisicaba, ngaleyo ndlela. ukuyiguqula ibe yizinhlangothi ezimbili).
• Gcoba ichopho lenduku ngamafutha omshini, bese ulifaka esihlalweni lapho kufanele ugaye khona idivayisi.
• Thatha noma iyiphi enye i-valve enobubanzi obufanayo bese uyifaka ku-chuck ye-screwdriver noma i-drill.
• Qondanisa amapuleti ama-valve amabili ukuze anamathele ndawonye nge-adhesive tape.
• Ukucindezela kancane i-drill noma i-screwdriver ngesivinini esiphansi, qala ukugaya. Into esetshenziswayo izozungezisa i-valve eyodwa, bese kuthi yona idlulisele ukunyakaza okuzungezayo ku-valve edonsayo. Ukuzungezisa kufanele kube kokubili phambili nokuhlehlayo.
• Izimpawu zokuphela kwenqubo zifana nalezi ezichazwe ngenhla.

Sicela uqaphele ukuthi izinjini eziningi zemishini yesimanje azikwazi ukuxhunywa ngamavalvu. Lokhu kungenxa yokuthi zenziwe nge-aluminium, futhi uma izakhi zenjini yomlilo zangaphakathi zonakaliswe kakhulu, kunengozi yokushintshwa kwe-valve njalo. Ngakho-ke, abanikazi bezimoto zakwamanye amazwe zesimanje kufanele baqhubeke nokucacisa lolu lwazi noma bafune kangcono usizo lwesevisi yemoto.

Khumbula ukuthi ngemuva kokushaya, awukwazi ukushintsha ama-valve ezindaweni, ngoba ukugoqa kwenziwa nge-valve ngayinye ngayinye.

Indlela yokuhlola izihlalo ze-valve

Ekupheleni kokugoqa kwama-valve, kubalulekile ukubheka ikhwalithi ye-lapping. Lokhu kungenziwa kusetshenziswa enye yezindlela ezimbili.

Indlela yokuqala

Indlela echazwe ngezansi iyona evame kakhulu, kodwa ngeke ihlale ikhombisa umphumela olungile ngesiqinisekiso esingu-100%. futhi, ayikwazi ukusetshenziselwa ukuhlola ikhwalithi yokugaya i-valve kuma-ICE afakwe i-valve ye-EGR.

Ngakho-ke, ukwenza isheke, udinga ukubeka ikhanda le-cylinder ohlangothini lwalo, ukuze izimbobo zemithombo lapho ama-manifolds axhunywe khona "bheka" phezulu. Ngakho-ke, ama-valve azotholakala endizeni enezingqimba, futhi izembozo zawo zizotholakala ziqondile. Ngaphambi kokuhlola ama-valve okwenziwayo, kuyadingeka ukomisa izitolo ze-valve ngosizo lwe-compressor ukuze unikeze ukubonakala kokuvuza okungenzeka kwephethiloli ngaphansi kwazo (okungukuthi, ukuze udonga oluqondile lome).

khona-ke udinga ukuthela uphethiloli emithonjeni eqondile (futhi uphalafini ungcono, ngoba unoketshezi olungcono). Uma ama-valve ehlinzeka ngokuqina, khona-ke i-parafini ethelwe ngaphansi kwayo ngeke iphume. Uma kwenzeka ukuthi uphethiloli ngisho namanani amancane aphuma ngaphansi kwama-valve, ukugaya okwengeziwe noma omunye umsebenzi wokulungisa kuyadingeka (kuye ngokuthi isimo esithile kanye nokuxilongwa). Inzuzo yale ndlela ukuthi kulula ukuyisebenzisa.

Nokho, le ndlela nayo inezinkinga zayo. Ngakho-ke, ngosizo lwayo akunakwenzeka ukuhlola ikhwalithi yokugaya i-valve lapho injini yomlilo yangaphakathi isebenza ngaphansi komthwalo (ukuvuza kwegesi ngaphansi komthwalo). futhi, ayikwazi ukusetshenziselwa ama-ICE afakwe i-valve ye-USR, ngoba ukwakheka kwawo kusho ukuba khona kwama-valve ahambisanayo kusilinda esisodwa noma ngaphezulu lapho uphethiloli uzothulula khona. Ngakho-ke, akunakwenzeka ukuhlola ukuqina ngale ndlela.

Indlela yesibili

Indlela yesibili yokuhlola ikhwalithi yokugaya i-valve iyindawo yonke futhi inokwethenjelwa kakhulu, ngoba ikuvumela ukuthi uhlole ukudlula kwamagesi ngama-valve angaphansi komthwalo. Ukwenza isheke elifanele, kuyadingeka ukubeka ikhanda le-cylinder "sibheke phansi", okungukuthi, ukuze izitolo (izimbobo) zama-valve zibe phezulu, futhi imigodi yemithombo yokuqoqa ihlangothini. khona-ke udinga ukuthululela inani elincane likaphethiloli (kulokhu, akunandaba ukuthi iyiphi, futhi ngisho nesimo sayo akusho lutho) emgodini wokuphuma kwe-valve (uhlobo lwepuleti).

Thatha i-compressor yomoya bese uyisebenzisela ukunikeza i-jet yomoya ocindezelwe ohlangothini kahle. Ngaphezu kwalokho, kuyadingeka ukuthi unikeze umoya ocindezelwe kokubili ekuvulekeni okuningana okudonsayo kanye nasekuvuleni okuningana kokukhipha umoya. Uma ukugoqa kwama-valve kwenziwa ngekhwalithi ephezulu, khona-ke ama-bubbles emoyeni ngeke aphume ngaphansi kwawo ngisho nangaphansi komthwalo ohlinzekwa yi-compressor. Uma kukhona ama-bubbles emoyeni, khona-ke akukho ukuqina. Ngakho-ke, ukuchelela kwenziwa kahle, futhi kuyadingeka ukucolisiswa. Indlela echazwe kulesi sigaba iphumelela ngokwedlulele futhi iguquguquka futhi ingasetshenziswa kunoma iyiphi i-ICE.

isiphetho

Ama-valve e-Lapping yindlela elula abanikazi bezimoto abaningi abangayiphatha, ikakhulukazi labo abanekhono lokukhanda. Into esemqoka ukuthi ube namathuluzi nezinto zokwakha ezifanele. Ungenza i-lapping paste yakho, noma ungathenga esenziwe ngomumo. Nokho, inketho yesibili ingcono. Ukuhlola ikhwalithi ye-lapping eyenziwe, kuyinto efiselekayo ukusebenzisa i-compressor yomoya ehlinzeka ngokuhlolwa kokuvuza ngaphansi komthwalo, lena indlela engcono kakhulu.
