Wire Rope Safety Factors for Mining Applications: Compact Strand Analysis
Mukushanda kwepasi pevhu uye pamusoro pemigodhi, kusarudzwa kwetambo kwetambo kwakakosha kune zvese kushanda zvakanaka uye kuchengetedzwa kwevashandi. Ichi chinyorwa chinoongorora zvakakosha kuchengetedza zvinhu zvemigodhi waya tambo, nekutarisa pane compact tambo zvivakwa.
Kunzwisisa Zvinhu Zvekuchengetedza muMigodhi Wire Ropes
Chengetedzo zvinhu zvinomiririra reshiyo pakati pehudiki hwekudambuka mutoro (MBL) wetambo yewaya uye nehukuru hwekushanda huchasangana nahwo. Pazvikumbiro zvemigodhi, masangano anodzora anowanzo raira zvishoma zvekuchengetedza zvinhu kubva pa5: 1 kusvika 10: 1 zvichienderana nemashandisirwo chaiwo.
Chinokosha Chekuchengetedza Factor Zvinodiwa neKushandisa
- Shaft Hoisting Ropes:Chengetedzo shoma ye7:1 kusvika 8:1 yekutenderedza dhiramu
- Balance Ropes:Chengetedzo shoma ye5:1
- Tambo dzekutungamira:Chengetedzo shoma ye5:1
- Tambo dzeSlope Haulage:Chengetedzo shoma ye6:1
- Crane uye Kusimudza Zvikumbiro:Chengetedzo shoma ye5:1 kusvika 6:1
Sei Compact Strand Inokosha muMigodhi
Compact strand tambo tambo dzinopa akati wandei mabhenefiti pamusoro pezvakajairwa tambo zvivakwa zvenzvimbo dzemigodhi:
- Higher Breaking Load:The compacted cross{{0}section inowedzera metallic area, inopa 10-15% yepamusoro pakutyoka simba zvichienzaniswa netambo dzakajairwa dzedhayamita imwe chete.
- Superior Abrasion Resistance:Kunze kwakatsetseka kunoderedza-kukwesha kwewaya uye kusapfeka kwekunze kubva pakubata zvisote nezvigubhu.
- Hupenyu Hwakawedzerwa Hwebasa:Kuderedzwa kwemukati kupfeka uye kunatsiridza kuneta kuramba kunoshandura kune yakareba kutsiva nguva.
- Zvirinani Drum Spooling:Iyo yakatsetseka, yakatenderedzwa tambo profiles inoita kuti yunifomu itenderere pamadhiramu akawanda-madhiramu.
Zvinhu Zvinokanganisa Kuchengetedza Factor Sarudzo
Paunenge uchitarisa iyo yakakodzera yekuchengetedza chinhu chemigodhi waya tambo, mainjiniya anofanirwa kufunga:
- Kudzika kwe shaft kana kurerekera
- Kukurumidza kushanda
- Frequency yekurodha macycles
- Mamiriro ekunze (corrosion, tembiricha, unyoro)
- Kuvapo kwekuremerwa kwekuvhunduka kana kuzunguzika
- Regulatory zvinodiwa zvakanangana nemasimba emigodhi
Kuongorora uye Retirement Criteria
Kuongorora nguva dzose kunokosha pakuchengetedza kuchengeteka. Tambo dzewaya dzinofanirwa kuregedzwa kana:
- Nhamba yewaya dzakatyoka inodarika muganhu unobvumirwa pakureba kwelayiti
- Kuderedzwa kwedhayamita kunodarika 10% kubva pazita
- Kuora kwakakosha kana gomba kunoonekwa
- Humbowo hwekukanganiswa kwechimiro (shiri, kinking, core protrusion)
Mhedziso
Kusarudza tambo yewaya yakakodzera ine kuchengetedzwa kwakakodzera chinhu chakakosha chekuchengetedza migodhi manejimendi. Tambo dzetambo dzakasungirirwa, dzine simba radzo rakawedzerwa uye hunhu hwekusimba, dzinopa mhinduro yakanakisa yekukumbira zvicherwa zvicherwa uko kuvimbika kusingagone kukanganisa.
