VFD Skid-Mounted Drilling Rig

Kufotokozera Kwachidule:

Kuwonjezera pa kukhala ndi mphamvu zowonjezera mphamvu, makina opangira magetsi a AC amalola woyendetsa kubowola kuti azitha kuyendetsa bwino zida zogwiritsira ntchito, motero amalimbitsa chitetezo chachitsulo ndi kuchepetsa nthawi yobowola. liwiro, ndipo kutembenuka kudzazindikirika ndi AC motor reversal.Pa AC powered rig, AC generator sets (injini ya dizilo kuphatikiza AC jenereta) imapanga ma alternating current omwe amayendetsedwa pa liwiro losinthika kudzera pa variable-frequency drive (VFD).

Pampu yamatope imayendetsedwa ndi ma VFD AC motors okwera pa skid yomweyo, yokhala ndi V-lamba wotumiza komanso mawonekedwe osavuta.

Tebulo lodziyendetsa lodziyimira palokha limayenda ndi liwiro lochepera la 1 + 1R / 2 + 2R, ndipo kutembenuka kudzachitika ndi kusintha kwa injini ya AC.

Pogwiritsa ntchito ukadaulo wa AC-DC-AC pagalimoto, tebulo lozungulira ndi Zojambula zimakhala ndi ma quadrant anayi akuthamanga komanso kuwongolera kwathunthu kwa digito.

Dynamic brake imatengedwa kuti ilowe m'malo mwa eddy current brake ngati mabuleki othandizira.

Kubowola kokha kumapezedwa ndi Drawworks main motor kapena mota yodziyimira payokha. Kuwongolera kwanzeru kwa chipika choyenda kumalepheretsa chipika cha korona ndi tebulo lozungulira kuti lisagundane.

Kulankhulana kwanthawi yeniyeni ndi maukonde kumapezeka pogwiritsa ntchito ukadaulo wa PROFIBUS.

K mtundu wa mast ndi woyenera kukhazikitsa Top Drive system ya mtundu wosiyana.

Sling shot kapena swing up substructure ndi mast amayikidwa kuti zida zonse zikhazikike pamalo otsika

Kugwiritsa ntchito mphamvu moyenera chifukwa champhamvu kwambiri (osachepera 95%), Mphamvu yayikulu nthawi zonse ngakhale pa liwiro lotsika.

Regenerative braking kuti muzitha kuyang'anira bwino zojambulazo.

Makina osavuta komanso otetezeka opangira makina owongolera ndikuwongolera magawo monga kulemera pa bit (WOB), kuchuluka kwa kulowa (ROP), ndi kuwongolera torque.
