Core Drill Bit

December 06 , 2021

Core Drill Bit The core drill bit breaks the bottom hole rock with a ring structure to drill the core, thereby forming a core pillar in the center. The core harvest rate and the speed of drilling are all related to the quality and selection of the drill bit. The structure design of the core bit should be conducive to improving the core harvest rate. The bit should be drilled smoothly to avoid vibration and damage to the core. Outer edge of the bit and the center of the borehole should be concentric. And inner cavity of the drill bit should be able to make the core claws as close as possible to the core entrance, so that the core can enter the core barrel through the core claws and be protected soon after it is formed, at the same time, it can be as close as possible to the core root when cutting the core , to reduce the residual core at the bottom of the well. According to different formations, the commonly used core bits for water well drilling rigs are divided into steel core bits, scraper core bits and diamond core bits.

HZ Series Hydraulic Core Drilling Rigs

November 29 , 2021

HZ Series Hydraulic Core Drilling Rigs The HZ series hydraulic core drilling rig is a portable drilling rig， also have a wide range of uses. It is suitable for geological survey of railways, water conservancy, bridges, dam foundations and other buildings, geological core drilling, small grouting holes, blasting holes, and water well drilling. Diamond drill bits, PDC drill bit and alloys drill bit can be used for drilling according to different formations. 1. With hydraulic automatic feed mechanism, it can improve drilling efficiency and reduce the labor intensity. 2. The ball clamp clamping mechanism is used to instead of the chuck, which can work by non-stop inverting rod, not only very convenient to operate,but also safe and reliable. 3. It equipped with a pressure gauge at the bottom of the hole, make it convenient for grasping the drilling situation in the hole. 4. It has a compact structure, centralized handle, small footprint, light weight, also easy to disassemble , and easy to move. So it is more suitable for plain area or mountainous areas operations. 5.Compare to the DTH Drilling, and Circulation drill, the UNIQUE brand HZ series Hydraulic core drilling rig is much smaller and cheaper, more suitable for small projects , and private works, reduce the economic burden.

Advantages of the Foam Pump for water well drilling rig

November 08 , 2021

Advantages of the Foam Pump for water well drilling rig 1.Prolonged the drill bit working life, and make the drill rigs less affected by the climate; 2. Improved the speed of returning slag; 3. During the drilling process , there is no need to use a mud pump, and there is no need to spend a lot of time to maintain the mud pump; 4. In the process of drilling, the aquifer is not easy to be blocked by drilling fluid, and the water volume is intuitively observed; 5. The torque used for drilling is much smaller than that for rotary drilling, and the rotary speed is also very low, generally 10-30r/min;
