API 5DP drill pombi irikutevera nescrew thread yekubatanidza rig yekuchera iri pazasi pemudziyo wekuchera pamusoro uye midziyo yeguyo kana yepasi yekubuda mudziyo.Chinangwa ndechekuchera madhaka ekuchera akaunzwa kuchibhorani, uye kudhirowa nekuwedzera, kuderera kana kutenderedza yepasi nzira yekubuda nayo.Drill pombi inofanirwa kukwanisa kumirisana nekumanikidza kukuru kwekunze, kumonyoroka, kukotama uye kudedera.Mumigodhi nemafuta uye gasi kunatsa maitiro, pombi yekuchera inogona kushandiswa kakawanda.
① Zvakadini nekambani yako?
Mumwe wevagadziri vanotungamira uye vatengesi vanonyanya kugadzira pombi dzekuchera muChina, vanonyanya kupa mapombi ekuchera anosanganisira oiri pombi yekuchera, yemvura pombi yekuchera, flat drill pombi, geological drill pombi uye isiri yekuchera pombi.Kunze kwemapombi ekuboorera isu tinokwanisawo kugovera zvakasiyana-siyana zvepipeline accessories, majoini ekuchera, simbi pombi fittings, mavharuvhu etc. rinosanganisira yedu-kumira kutengesa.Iyo yakasanganiswa yekutengesa & sevhisi inovimbisa vatengi vane zvakasiyana zvinodiwa kuwana nyore kwekutenga manejimendi.
②Ungavimbisa sei kunaka kwezvigadzirwa?
Isu takagadzira iyo yepasi rose advanced quality management system, chese chinongedzo kubva kune yakabikwa kusvika kune yekupedzisira chigadzirwa tine yakasimba yemhando bvunzo; Isu takatsunga kumisa zvigadzirwa zvisina kukodzera zvinoyerera mumusika.Panguva imwecheteyo, tichapa inodiwa yekutevera sevhisi yebasa.
③Tinokwanisa kugamuchira chigadzirwa kwenguva yakareba sei mushure mekutenga?
Mukutenga kwechigadzirwa mukati memazuva manomwe ekushanda, Ticharonga kuburitsa fekitori nekukurumidza.
