Tricone Drill Bit Wear Classification Standards uye Wear Analysis

International Contractor Association Wear Classification Standards

Sangano reInternational Contractor Association rinoisa chibooreso chekupfeka muzvikamu zvitatu: kupera kwemazino, kutakura kupfeka, uye kuderedzwa kwedhayamita, zvine mwero wakaiswa pachikamu chimwe nechimwe. Aya mapoka anoshanda kune akasiyana marudzi ezvidimbu zvetricone drill, kusanganisiraisa zvimedu zvekubooresa zino,akagaya zino trione bits, inoshandiswa mukuchera mafuta, gasi, uye kuchera matsime emvura.

①Zino Wear Classification Standard

Kupfeka mazino kunokamurwa kuita nhanho 8, iine mazinga akasiyana emazino akagayiwa nemazino ekuisa. Formilled zino trione bits, kupatsanurwa kunobva pakukwirira kwekupfeka. Kana hurefu hwekupfeka huri mukati me1/8 yehurefu hwezino, hunotsanangurwa seNhamba 1. Kana urefu hwekupfeka huri pakati pe1/8 ne2/8 yehurefu hwezino, iNhare 2, zvichingodaro kusvika kuNhamba 8. Iyi chiyero inonyanya kukosha kunemilled zino trione bitsuyedhonza zvimeduinoshandiswa mumhando dzakapfava.

Fortungsten carbide isa mazino, kupatsanurwa kunobva pachiyero chenhamba yemazino akatyoka kana akarasika kusvika kuhuwandu hwemeno. Kana nhamba yemazino akatyoka kana akarasika ari mukati me1/8 yehuwandu, inorongwa seNhamba 1. Kana nhamba yemazino akatyoka kana akarasika iri pakati pe1/8 ne2/8 yehuwandu, iNhoroondo 2, zvichingodaro kusvika paNhamba 8. Izvi zvinoshanda kuTungsten Carbide Tricone Drill Bitnemamwe madhizaini ekuisa mazino.

Kupfeka mazino kunoratidzwa ne "T", ine T1 inomiririra Level 1 kupfeka, T2 inomiririra Level 2 kupfeka, zvichingodaro.

② Kutakura Wear Classification Standard

Kupfeka kwekutakura kunoiswa pachiyero chenguva yekushandiswa kwebit kune hupenyu hwese hwekutakura (mumaawa), iine 8 nhanho dzekuisa. Kune marudzi ese etrione rotary drill bits,kusanganisirazvimedu zvekuchera matsime emvurauyetrione rock bits, kana nguva yekushandiswa inosvika 1/8 yehupenyu hwekutakura, inorondedzerwa seNhamba 1. Kana nguva yekushandiswa inosvika 2/8 yehupenyu hwekutakura, iNhare 2, uye zvichingodaro kusvika kuNhamba 8. Kana nguva yekushandiswa inowira pakati pematanho maviri, iyo yepamusoro inogoverwa.

Kutakura kupfeka kunoratidzwa ne "B", neB1 inoratidza kuti 1/8 yehupenyu hwekubereka yakashandiswa, B2 inoratidza 2/8, zvichingodaro. Kune akavharidzirwa mabheji, iyo yekuisa chisimbiso inoiswa muzvikamu zvitatu:

- SE (Kuisa Chisimbiso Kunoshanda)

- SF (Kuisa chisimbiso kusingashande)

- SQ (Kuisa Chisimbiso Dambudziko)

Zvikamu izvi zvinonyanya kukosha kuneTCI drill bitsuye mamwe maitiro epamusoro etricone rock bits.

③Bit Diameter Wear Representation

Kuratidza kupfeka padhayamita yebhiti, "1" inomiririra kuti bhiti rinochengeta dhayamita raro rekutanga, nepo "0" inoratidza kuti dhayamita yakadzikiswa. Kuwanda kwekuderedzwa kwedhayamita kunoratidzwa mumasendimita mushure me "0". Semuenzaniso, "01/2" zvinoreva kuti dhayamita yebhiti yakaderedzwa ne 1/2 inch. Izvi zvakakosha pakuchengetedza kunyatsoita basa rekuchera mumashandisi akasiyana siyana, kusanganisiramafuta, gasi, uyekuchera tsime remvura.
