Statyb\u0173, kasybos ir \u017eem\u0117s kasimo darbuose kuliniai dantys yra labai svarb\u016bs projekto efektyvumui u\u017etikrinti. Ta\u010diau j\u0173 tarnavimo laikas priklauso nuo daugelio veiksni\u0173. J\u0173 supratimas gali pad\u0117ti optimizuoti na\u0161um\u0105, suma\u017einti i\u0161laidas ir priimti sprendimus d\u0117l pirkimo.<\/span><\/span><\/div>\n

1.1 Danties korpuso med\u017eiagos<\/span>\u200b<\/span><\/div>\n
Kulkos dant\u0173 korpusuose paprastai naudojami legiruoti konstrukciniai plienai, pavyzd\u017eiui, 42CrMo. \u017demos kokyb\u0117s plienas yra nepakankamai tvirtas ir kietas, tod\u0117l esant \u012ftempiams deformuojasi arba l\u016b\u017eta. Auk\u0161tos kokyb\u0117s plienas, palyginti su nekokybi\u0161ku plienu, gali dvigubai pailginti veikimo laik\u0105 prie\u0161 pasirei\u0161kiant pa\u017eeidimams.<\/span><\/span><\/div>\n
<\/div>\n
1.2 Karbido antgali\u0173 med\u017eiagos<\/span>\u200b<\/span><\/div>\n
Karbido antgaliai, da\u017enai pagaminti i\u0161 volframo ir kobalto lydini\u0173, lemia atsparum\u0105 dilimui. Didelio grynumo tinkamos sud\u0117ties lydiniai pasi\u017eymi geresniu kietumu. Dantys su kokybi\u0161kais karbidiniais antgaliais gali ilgiau 40% tarnauti ant abrazyvini\u0173 pavir\u0161i\u0173 nei dantys su prastos kokyb\u0117s med\u017eiagomis.<\/span><\/span><\/div>\n

2. Projektavimas ir gamyba<\/span><\/strong><\/span><\/div>\n
\u200b<\/span><\/div>\n
2.1 Strukt\u016brinis projektavimas<\/span>\u200b<\/span><\/div>\n
Svarbu forma, kampas ir danties \u017eingsnis. K\u016bgin\u0117s, supaprastintos konstrukcijos suma\u017eina pasiprie\u0161inim\u0105 ir tolygiai paskirsto \u012ftamp\u0105. Tradiciniai plok\u0161ti profiliai arba neteisingi kampai didina trint\u012f ir netolygi\u0105 apkrov\u0105, tod\u0117l grei\u010diau d\u0117visi.<\/span><\/span><\/div>\n
\u200b<\/span><\/div>\n
2.2 Gamybos b\u016bdai<\/span>\u200b<\/span><\/div>\n
Svarbiausia - tikslumas. Labai svarbus tikslus milteli\u0173 mai\u0161ymas, terminis apdorojimas ir suvirinimas. D\u0117l blogo suvirinimo susilpn\u0117ja antgalio ir korpuso jungtis, o d\u0117l netinkamo terminio apdorojimo suma\u017e\u0117ja med\u017eiagos eksploatacin\u0117s savyb\u0117s. M\u016bs\u0173 grie\u017eta kokyb\u0117s kontrol\u0117 u\u017etikrina auk\u0161\u010diausios klas\u0117s gaminius.<\/span><\/span><\/div>\n

3. Darbo s\u0105lygos<\/span><\/strong><\/span><\/div>\n
\u200b<\/span><\/div>\n
3.1 Geologin\u0117s s\u0105lygos<\/span>\u200b<\/span><\/div>\n
Dirvo\u017eemio ir uolien\u0173 tipo sm\u016bginis dilimas. Mink\u0161tas dirvo\u017eemis d\u0117visi l\u0117tai, o kietos uolienos, pavyzd\u017eiui, granitas arba uolienos su kvarco mineralais, gali greitai sutrumpinti danties tarnavimo laik\u0105. Kvarco mineral\u0173 turtingose uolienose dantis gali prireikti keisti kas 100 metr\u0173, o mink\u0161tose nuos\u0117din\u0117se uolienose - kas 500 metr\u0173.<\/span><\/span><\/div>\n
\u200b<\/span><\/div>\n
3.2 Veiklos intensyvumas<\/span>\u200b<\/span><\/div>\n
Nepertraukiamai dirbant intensyviai, dantys patiria \u012ftamp\u0105 ir kar\u0161t\u012f, tod\u0117l grei\u010diau d\u0117visi. Vis\u0105 par\u0105, 7 dienas per savait\u0119 vykstan\u010dios kasybos operacijos dantis gali nusid\u0117v\u0117ti daug grei\u010diau nei pertraukiamos.<\/span><\/span><\/div>\n

4. \u012eranga ir veikimas<\/span><\/strong><\/span><\/div>\n
\u200b<\/span><\/div>\n
4.1 \u012erangos suderinimas<\/span>\u200b<\/span><\/div>\n
Kulkos dantys turi atitikti \u012frang\u0105. Netinkami dantys sukelia ne\u012fprast\u0105 \u012ftamp\u0105, prie\u0161laikin\u012f nusid\u0117v\u0117jim\u0105 arba l\u016b\u017eim\u0105. Netinkami dyd\u017eiai gali sukelti klib\u0117jim\u0105 ir netolygi\u0105 apkrov\u0105.<\/span><\/span><\/div>\n
\u200b<\/span><\/div>\n
4.2 Operatoriaus praktika<\/span>\u200b<\/span><\/div>\n
Netinkamas naudojimas, pavyzd\u017eiui, itin didelis pjovimo kampas arba perkrovimas, gali akimirksniu sugadinti dantis. Apmokyti operatoriai, laikydamiesi proced\u016br\u0173, gali prailginti dant\u0173 tarnavimo laik\u0105 iki 30%.<\/span><\/span><\/div>\n
\u200b<\/span><\/div>\n
Trumpai tariant, kulkos dant\u0173 tarnavimo trukmei \u012ftakos turi med\u017eiagos kokyb\u0117, konstrukcija, eksploatavimo s\u0105lygos ir \u012frangos bei operatoriaus veiksniai. M\u016bs\u0173 gaminiai, pagaminti i\u0161 auk\u0161\u010diausios kokyb\u0117s med\u017eiag\u0173, su optimizuotu dizainu ir grie\u017eta gamyba, kartu su m\u016bs\u0173 ekspert\u0173 patarimais u\u017etikrina did\u017eiausi\u0105 vert\u0119 ir ilg\u0105 tarnavimo laik\u0105.<\/span><\/span><\/div>","protected":false},"excerpt":{"rendered":"
