Ukukhethwa kweBlade yeSaw yeConcrete vs Asphalt

Ukukhetha iblade yesarha yekhonkrithi esebenzayo kuqala ngezinto ezisetyenzisiweyo, kungekhona ububanzi beblade. Ikhonkrithi kunye ne-asphalt zinokusikwa ngeeblade zedayimani, kodwa zinxiba i-bond yesinyithi ngeendlela ezahlukeneyo. Ikhonkrithi eqinileyo idla ngokuyithuntubeza idayimani eveziweyo ngaphambi kokuba i-bond ejikelezileyo iguge, ngelixa i-asphalt erhabaxa inokususa i-bond ngokukhawuleza kwaye ihlasele nombindi wentsimbi ongaphantsi kwamacandelo.

Oku kudala umthetho wokukhetha ovakala ubuyela umva kancinci: izinto eziqinileyo, ezingarhawuzekiyo zihlala zifuna ikhonkco elithambileyo, ngelixa izinto ezithambileyo kodwa ezirhawuzelela kakhulu zihlala zifuna ikhonkco eliqinileyo. Ikhonkco elithambileyo likhupha iidayimani ezigugileyo kwaye liveze iindawo ezintsha zokusika. Ikhonkco eliqinileyo licothisa ukuguguleka xa kusikwa i-asphalt okanye ikhonkrithi eluhlaza. UNorton uchaza oku njengolwalamano "oluchaseneyo olutsalayo" phakathi kwekhonkco leblade kunye nezinto ezisikiweyo.

I-Concrete Blade vs Asphalt Blade: Ukuthelekisa okuKhawulezayo

Kutheni iConcrete kunye neAsphalt zifuna iiBlade Bonds ezahlukeneyo

Incakuba yedayimani inqumla ukuguguleka okulawulekayo. Iidayimani eziveziweyo ziyasila izinto, ngelixa iqhina lesinyithi elizijikelezileyo liwohloka kancinci kancinci. Njengoko iidayimani ezindala ziba buthuntu okanye ziqhekeka, iidayimani ezintsha kufuneka zivele ngesantya esifanayo. Xa inkqubo ihlala ilungelelene, incakuba iyaqhubeka nokusika ngaphandle kokulahlekelwa bubude becandelo ngokukhawuleza.

Ukuba i-bond inzima kakhulu kwizinto ezisetyenzisiweyo, isenokungagugi ngokukhawuleza ukuze iveze iidayimani ezintsha. Ubuso be-segment buba buthambile, isantya sokusika siyehla kwaye i-blade iqala ukugquma. Ukuba i-bond ithambile kakhulu, i-metal matrix iyanyamalala ngaphambi kokuba iidayimani zisetyenziswe ngokupheleleyo. Isarha isenokuqhubeka phambili, kodwa uhlahlo lwabiwo-mali lwe-blade luya kuhamba kwicala elahlukileyo.

I-Asphalt idala enye ingxaki eyaziwa ngokuba kukusika ngaphantsi. Amasuntswana arhabaxa anokugquma umbindi wentsimbi ngqo ngaphantsi kwamacandelo edayimani, nto leyo ebangela ukuba unxibelelwano phakathi kwecandelo kunye nomzimba we-blade lube buthathaka. UNorton ucebisa ukuba kubekho izikhuseli ezirhabaxa okanye uyilo olufanayo lwecandelo lezinto ezirhabaxa, ngelixa uHilti esebenzisa amacandelo aqingqiweyo aqingqiweyo kwi-SPX asphalt blade yakhe. Yingakho i -asphalt saw blade kufuneka ihlolwe ngaphantsi kwecandelo kunye nakumaleko wedayimani obonakalayo.

Chonga Izinto Ezifunekayo Ngaphambi Kokukhetha I-Blade

Ikhonkrithi eQinisiweyo neQinisekisiweyo

Ikhonkrithi ecociweyo akufuneki iphathwe njengesixhobo esinye esifanayo. I-aggregate idla ngokuba nefuthe elikhulu kwindlela esebenza ngayo iibhleyidi kunamandla ekhonkrithi ashicilelwe kwitikiti yokuhambisa. I-aggregate eqinileyo inokunyusa umngcipheko wokugquma xa ibhondi iguga kancinci, ngelixa i-aggregate ethambileyo okanye erhabaxa inganciphisa ubomi becandelo.

Ikhonkrithi eqinisiweyo yongeza intsimbi kwindlela yokusika. Ngenxa yoko, i-blade kufuneka ilinganiswe kwikhonkrithi nakwi-rebar, kwaye isarha kufuneka inike amandla aneleyo ukugcina isantya sokusika esizinzileyo. I-blade esika kancinci ayisoloko igugile. I-Norton idwelisa i-bond eqinileyo kakhulu, izinto eziqinileyo kunye namandla angonelanga oomatshini phakathi kwezizathu eziqhelekileyo zokugquma. Ukuba i-blade ifuna ukugqunywa ngokuphindaphindiweyo, ukutshintshela kwi-bond ethambileyo kudla ngokuba luncedo ngakumbi kunokugoba kakhulu kwisibambo.

Ikhonkrithi eluhlaza

Ikhonkrithi eluhlaza ifuna iblade eyahlukileyo kunye nendlela yokusika. I-Husqvarna ithi inkqubo yayo ye-Soff-Cut Ultra Early Entry ingaqala ukusika amalungu okucutha malunga neyure enye ukuya kwezimbini emva kokucoca itrowel nangaphambi kokuba iseti yokugqibela ibekwe . Ifestile echanekileyo isaxhomekeke kumxube, ubushushu beslab kunye neemeko zokugqiba, kodwa uluhlu olupapashiweyo luchaza isizathu sokuba iiblade zokungena kwangoko zahluke kwiiblade zekhonkrithi ezilungisiweyo.

Kule nqanaba, intlama yesamente isakhula ngamandla, ngelixa isanti ekhululekileyo kunye ne-aggregate zinokuhlala zirhabaxa kakhulu. I-blade kufuneka yenze i-joint ngaphandle kokukrazula imiphetho okanye ukubangela ukuqhekeka komphezulu. Ikhonkrithi eluhlaza isenokuba intsha, kodwa sele ifundile indlela yokwenza ukukhetha ii-blade kube nzima.

I-Asphalt Phezu Kwekhonkrithi

Ukulungiswa kwendlela ngamanye amaxesha kufuna ukunqunyulwa kube kanye ukuze kudlule phezu kwe-asphalt overlay kuze kuqhubeke kwisiseko sekhonkrithi. I-asphalt blade ezinikeleyo inokunciphisa isantya emva kokufikelela kwikhonkrithi eqinileyo, ngelixa i-concrete blade inokulahlekelwa zizinto ezibophayo ngokukhawuleza kumaleko we-asphalt. Kwiindlela ezixutyiweyo ngamanye amaxesha, i-asphalt-over-concrete okanye i-blade esetyenziswa ngokubanzi inokunciphisa isidingo sokutshintshwa kwe-blade.

Ukuze wenze umsebenzi omde wemveliso, thelekisa ixabiso leblade, iimitha zokusika ezigqityiweyo kunye nexesha lokutshintsha iblade kwiblade enye yezinto ezixutyiweyo ngokuchasene neeblade ezimbini ezizinikeleyo. Ngaphandle kwezo zibalo, ukubiza enye indlela ngokuthi “ixabiso eliphantsi” ikakhulu kukuthembela ekubeni nethemba xa unxibe umnqwazi oqinileyo.

Tshatisa iDayimane Blade neConcrete Saw

Nje ukuba izinto kunye nebhondi zikhethiwe, iblade kufuneka ihambelane nomatshini. Jonga ububanzi beblade, ubungakanani be-arbor, ulungiselelo lwe-drive-pin, i-RPM ephezulu, amandla esarha kunye nokwamkelwa okumanzi okanye okomileyo njengenkqubo enye. Iblade ingangena phezu kwe-arbor kodwa ingafaneleki kwisantya se-shaft, i-guard okanye amandla akhoyo.

Ubudlelwane phakathi kobubanzi kunye ne-RPM bucacile kuluhlu lwe-MK Diamond's MK-3000. Ulwakhiwo lwayo lwe-20-intshi lusebenza kwi-2,580 rpm kwaye lufikelela kubunzulu bokusika obupapashwe malunga ne-191 mm. Inguqulelo ye-26-intshi isebenza kwi-2,030 rpm kwaye ifikelela malunga ne-267 mm, ngelixa inguqulelo ye-30-intshi isebenza kwi-1,680 rpm kwaye inqumla ukuya malunga ne-318 mm.

La manani asebenza kuluhlu lwesarha enye, kodwa isifundo sobunjineli sibanzi: njengoko ububanzi beblade bukhula, isantya esichanekileyo somngxuma sihlala sitshintsha. Iblade enkulu kakhulu ayinakufakelwa ngokukhuselekileyo ngokujonga umngxuma we-arbor yodwa.

Ubungakanani beBlade yeSaw yeConcrete kunye nobunzulu bokusika

I-Blade radius ayifani nobunzulu bokusika obusebenzisekayo. I-arbor, i-flange, i-guard kunye ne-chassis zihlala kwinxalenye ye-radius, ngelixa ukuguguleka okuqhelekileyo kwecandelo kuyinciphisa ngakumbi. I-MK Diamond idwelisa ubunzulu bokusika obumalunga ne-102 mm kwi-blade eyi-12 intshi, i-127 mm kwi-blade eyi-14 intshi, i-178 mm kwi-blade eyi-18 intshi kunye ne-203 mm kwi-blade eyi-20 intshi.

Ukusika okufunekayo kwe-100 mm kushiya malunga ne-2 mm kuphela yomda wethiyori xa kuthelekiswa nexabiso lereferensi ye-102 mm yeblade eyi-intshi ezili-12. Loo mda awuvumeli ukuguguleka kweblade, ubungakanani beflange, indawo yokukhusela okanye i-slab engalinganiyo. Ukhetho lokugqibela ke ngoko kufuneka lulandele uluhlu lweblade oluvunyiweyo lomenzi wesarha kunye nobunzulu bokusika obulinganisiweyo.

Idatha yomatshini we-ACE inika umzekelo osebenzayo. Isarha yendlela yekhonkrithi ye-QF400 yamkela i-blade eyi-400 mm kwaye inobunzulu obukhulu bokusika obupapashweyo be-130 mm. Umsiki wekhonkrithi kunye ne-asphalt we-QF500 isebenzisa incakuba engama-500 mm kwaye ifikelela kwi-180 mm. Olu vavanyo loomatshini luluncedo ngakumbi ekuthengeni kunokuqikelela ubunzulu ukusuka kububanzi bencakuba kuphela.

Ilaphu Lokusika Lekhonkrithi Elimanzi vs Elomileyo

Ukusikwa okumanzi kunceda ukupholisa iblade kunye nokuthutha ukungcola okusikiweyo, kodwa ikwayindlela yokulawula ukuvezwa. Phantsi komgangatho we-US OSHA wokwakha i-silica, inqanaba lesenzo se-silica ekristale ephefumlayo yi- 25 μg/m³ , ngelixa umda wokuvezwa ovumelekileyo yi- 50 μg/m³ . Zombini ezi zibalo zilinganiswa njenge-avareji yexesha leeyure ezisibhozo.

Itheyibhile 1 ye-OSHA ifuna ukuba iisarha ezisetyenziswa emva komatshini zisebenzise inkqubo edibeneyo yokuhambisa amanzi enika amanzi rhoqo kwincakuba. Umsebenzi wangaphandle owenziwa phantsi kwale ndlela awubonisi mfuneko yokongeza yokuphefumla, ngelixa umsebenzi wangaphakathi okanye ovalelwe ngaphakathi ufuna ubuncinane ukhuseleko lokuphefumla lwe-APF 10. Le mithetho isebenza kumsebenzi wokwakha ogutyungelweyo e-US; abakhi kwezinye iimarike kufuneka balandele imigaqo yasekuhlaleni.

Ukusika okomileyo kuhlala kuluncedo xa uludaka lungenakulawuleka okanye amanzi engafumaneki, kodwa zombini iblade kunye nesarha kufuneka zivunywe ukuze zisebenze okomileyo. Ubunzulu bokudlula, ixesha lokusika eliqhubekayo kunye namaxesha okupholisa kufuneka kulandele imiyalelo yezixhobo ezikhethiweyo endaweni yomthetho wexesha eliqhelekileyo. Ileyibhile emanzi kuphela ngumda wokusebenza, ayilocebiso elihle.

Iimpazamo zokukhetha i-Common Concrete Saw Blade

Iimpazamo eziqhelekileyo ziquka ukukhetha kuphela ngobubanzi, ukusebenzisa i-blade yekhonkrithi ngokuphindaphindiweyo kwi-asphalt, ukungawunaki umlinganiselo we-aggregate, ukudlula umlinganiselo we-RPM yomatshini kunye nokucinga ukuba yonke i-blade yekhonkrithi inokusika ukuqina okunzima. Enye impazamo eqhelekileyo kukukhetha i-blade enkulu yobunzulu obungaphezulu ngaphandle kokujonga ukuba isarha inamandla aneleyo na okugcina isantya esichanekileyo sokusika.

Jonga iblade ngexesha lesigaba sokuqala sokusika. Ubuso besigaba esigudileyo, uthuli olucolekileyo kunye nesantya sokusika esiwayo kunokubonisa ukuba i-glaze iphelile. Ukulahleka kwesigaba ngokukhawuleza kubonisa ukuba i-bond iyaphela ngokukhawuleza. Ukunqumla ngaphantsi kwesigaba kukhomba kwizinto ezirhabaxa, amanzi aneleyo okanye iblade engenalo ukhuseleko olufanelekileyo. Ezi mpawu ziluncedo ngakumbi kunokulinda iblade ukuba ingenise isikhalazo esisemthethweni.

Uluhlu lokujonga uKhetho lweeBlade zeSaw zeConcrete

Ngaphambi kokuba u-odole, qinisekisa ukuba izinto ezisetyenzisiweyo zichanekile, ubudala besamente, imeko ehlanganisiweyo, uqinisekiso, ubunzulu bokusika obufunekayo, imodeli yesarha, ububanzi beblade, ubungakanani be-arbor, i-RPM ephezulu kunye nendlela yokusika evumelekileyo. Emva koko thelekisa ixabiso leblade ngemitha nganye egqityiweyo endaweni yexabiso lokuthenga lodwa.

Khetha iblade yokusika ikhonkrithi eyenzelwe umsebenzi wekhonkrithi ovundisiweyo okanye oqinisiweyo. Sebenzisa iblade ye-asphalt enebhondi efanelekileyo kunye nokhuseleko olungaphantsi kwendlela yokuhamba ngeenyawo erhabaxa. Khetha iblade yezinto ezixutyiweyo ezivunyiweyo xa ukusika kudlula i-asphalt kunye nekhonkrithi ngokuphindaphindiweyo. Udidi lweblade lwenza uluhlu olufutshane; iinkcukacha zezinto kunye nomatshini zenza isigqibo sokugqibela.

Imibuzo ebuzwa qho
