| 地質(zhì)螺旋鉆桿系列 | ||||||||||
| 地質(zhì)螺旋鉆桿是我公司在地質(zhì)鉆桿高扭矩性能的基礎(chǔ)上，采用單螺旋葉片或雙螺旋葉片，經(jīng)預(yù)應(yīng)力纏繞工藝加工焊接而成。 鉆桿桿體選用優(yōu)質(zhì)地質(zhì)專用合金鋼管，鉆桿接頭選用優(yōu)質(zhì)合金結(jié)構(gòu)鋼，經(jīng)真空調(diào)質(zhì)處理，大大提高了抗疲勞強(qiáng)度和抗剪切強(qiáng)度。 采用先進(jìn)的摩擦焊焊接生產(chǎn)工藝，鉆桿具有抗彎強(qiáng)度高，焊接牢固等特點(diǎn)。 生產(chǎn)設(shè)備完全采用先進(jìn)的數(shù)控加工設(shè)備，具有生產(chǎn)效率高、質(zhì)量穩(wěn)定的特點(diǎn)。能夠保證深孔鉆進(jìn)時(shí)對(duì)直線度的要求。超低螺旋的螺旋葉片設(shè)計(jì)使該產(chǎn)品具有扭矩大，排渣速度快，鉆孔成型好，不易卡鉆的特點(diǎn)。特別適合于通水排渣效果不好的松軟煤層和類煤巖的深孔鉆探。 直徑Φ73以下的地質(zhì)螺旋鉆桿，可與各種全液壓鉆機(jī)直接配套使用，利用鉆機(jī)直接夾裝鉆桿螺旋外圓進(jìn)行鉆進(jìn)和更換鉆桿，方便快捷，大大降低了操作人員的勞動(dòng)強(qiáng)度。在超松軟高壓煤層條件下的鉆孔，采用套鉆施工工藝時(shí)，可選用直徑為90，113，133，146的大螺旋地質(zhì)鉆桿，便捷實(shí)現(xiàn)巖芯管的鋪設(shè)安裝。本系列產(chǎn)品為礦井的高效深孔鉆探提供了保證，填補(bǔ)了國(guó)內(nèi)空白。 |

| Geological spiral drill rod Spiral craft: prestressed wire winding and welding with single strip steel or double strip steel, based on the big torque of geological drill rod. Material of rod body: geological alloy pipe Material of connector: first-class alloy constructional steel Craft: thermal refining in vacuum, which greatly improves the fatigue resistance and shearing strength. Rod body craft: friction welding, which improves the bending strength and the firmness of the drill rod. Production facility: CNC machining equipment, which guarantees the high production efficiency, steady quality and straightness. Design feature: overlay spiral. It guarantees big torque, quick slagging, and clear hole forming. Besides, the drill bit will hardly get stuck. Application: soft coal bed, and other formation similar to coal bed, which is hard to drain and deslag. Matching: Geological spiral drill rod, diameter not bigger than 73mm: match all kinds of hydraulic driver drill. When drill super soft high pressure coal seam, diameter 90mm, 113mm, 133mm, 146mm will be recommended. It will be more convenient to lay and install core barrel. This kind of drill rod guarantees high efficiency of drilling work, which stops a gap in China. |
