Product Details

إن Kaishan K40 هو لقمة زر بت تعمل بالطرق السفلي من خط أدوات الحفر، وتؤدي دور الطرف القاطع في سلسلة DTH في الصخور الصلبة والكاشطة. يحمل جسمها المصنوع من الفولاذ السبائكي أزرار كربيد التنجستن على وجه مستوٍ أو محدب، مع ساق مسننة وثقوب غسل وحلقة تثبيت. تنتقل الصدمة من ساق مطرقة DTH عبر الأزرار بينما يزيل الهواء المضغوط القطع الصخرية، مما يجعلها مناسبة لأعمال التعدين والمحاجر وآبار المياه والطاقة الحرارية الأرضية. وهي تتوافق مع مطارق وقضبان DTH القياسية، وتدعمها Kaishan بضمان ودعم فني وقطع غيار وتدريب للمشغلين.

Working Principle

DTH (Down-The-Hole) drill bits operate at the bottom of the drill string, directly impacting the rock with high-frequency percussion. The bit is connected to a DTH hammer, which is powered by compressed air. The hammer's piston strikes the bit's shank, transmitting energy to the tungsten carbide buttons that crush and fracture the rock. Simultaneously, the bit rotates slowly, allowing the buttons to engage fresh rock surfaces. Compressed air is directed through flushing holes in the bit to lift cuttings to the surface, keeping the hole clean. The K40 bit's design optimizes this process by ensuring efficient energy transfer, uniform button wear, and effective hole cleaning, resulting in high penetration rates and extended service life.
