Bomba la Kuchimba Uzito Mzito
Bomba la kuchimba visima nzito ni eneo la mpito kati ya kola ya kuchimba na bomba la kuchimba.Haiwezi tu kupunguza mkazo katika uunganisho wa kola ya kuchimba visima na bomba la kuchimba visima, lakini pia kupunguza kuvaa kwa OD.
Bomba muhimu la kuchimba uzani mzito limetengenezwa kutoka kwa kipande kimoja cha upau thabiti wa AISI 4145H, kimetibiwa kikamilifu na joto, sifa zote za kimwili zinapatana na toleo la hivi punde la API spec7.
Ufungaji mgumu wa upinzani wa uvaaji wa HWDP ni kawaida kwenye viunganishi vya viungo vya zana na mshtuko wa kati.Aina za bendi ngumu ni pamoja na Arnco 100XT na100XT.nyuzi zote ni phosphated, copperized au baridi kazi.Viunganisho vyote vina vifaa vya kulinda nyuzi za chuma zilizoshinikizwa.Matangazo yote yametengenezwa kwa lathe za CNC -nyuzi zenye mabega mawili na maalum.
