Casing Advancing Systems ODEX 140
Eccentric casing drilling system ndiyo nzira yemazuva ano yakasarudzwa yekuchera mumamiriro ezvinhu akaoma pasi, somuenzaniso, pane matombo kana maumbirwo asina kusimba.EDS ndiyo inonyanya kugadzirisa hupfumi nokuti bapiro rayo rekugadzirisa bhiti rinodzorerwa rinogona kushandiswa pane gomba rinotevera.Izvi zvinonyanya dhizaini yemakomba asina kudzika, sezvinowanzoitika mukuchera matsime emvura, matsime egeothermal uye neakadzika micro-piling basa.EDS yakanakira maburi mapfupi mukuremerwa kwakabatanidzwa.Icho chikamu cheEccentric system chine Pilot bits, Reamer bits, Dhairira mudziyo uye casing shangu.
Pakuchera, reamer bit inotenderera kunze kuti ikure gomba iro rinokwana kuti casing chubhu inotsvedza kuseri kweiyo reamer.Kana yasvika kudzika kunodiwa, pombi yekuboorera inodhiza ichienda kumashure uye iyo reamer bit inodzokera shure, iyo iri kubvumira iyo yese yekuchera system kuti ipfuure nepakati casing.
Iyo pazasi saizi yeEccentric masisitimu anowanikwa, uye dhizaini yakakosha iri pane zvinodiwa nemutengi:
Eccentric 90, Eccentric 114, Eccentric 140, Eccentric 165, Eccentric 190 uye Eccentric 240
Application
- Geothermal tsime rekuchera
- Kuchera matsime emvura
- Pombi denga (umbrella arch drilling)
- Foundation basa
- Anchoring

Kushandisa:
1. Mukusagadzikana kwedombo kuumbwa, iyo casing inofanirwa kutevera.
2. Kazhinji mumvura kuchera matsime, nokuda kwegomba guru rinofinha.
3. Kuchera kudzika kuri nani kusingasviki 40 metres kudzora gomba zvakanaka.
4. Match kusvika 6" sando uye 194mm casing chubhu.
5. Air pressure ndeye 20 Bar uye air volumn i500 cfm.
6. Zvishandiso zvinotorwa kuti zvishandiswe mumakomba anotevera.
