Une barre de forage est un long tube en acier qui est utilisé pour transférer la rotation et le couple du moteur de forage au bit de forage. La barre de forage est généralement conique à une extrémité, ce qui lui permet de se connecter à d'autres barres ou à un bit de forage. Les barres de forage sont disponibles dans une variété de tailles et de configurations, en fonction des exigences spécifiques du projet de forage.

Second, the use and characteristics of the drilling rig:
1). Use:
Engineering anchoring drill can be used in urban construction, railway, highway, river, hydropower and other projects to drill rock anchor hole, anchor hole, blasting hole, grouting hole and other drilling construction.

At its core, submarine hammer drilling employs a powerful hammer mechanism to drive a drill bit into the seabed. The system utilizes both air and water pressure to deliver repeated impacts on the drill bit, which enables it to break through hard rock formations or sediments that might hinder installation efforts for marine infrastructure. The design of the hammer ensures that the energy is efficiently transmitted to the drill bit, allowing it to operate at significant depths.

The directed drilling rod market is observing several trends that reflect its evolving landscape. One significant trend is the increasing adoption of sustainable practices within the industry. Companies are prioritizing eco-friendly solutions, leading to a demand for drilling rods made from sustainable materials and designed to reduce environmental impact.

Sustainable drilling practices also include the use of biodegradable drilling fluids and systems that reduce the risk of leakage and contamination. Mining companies are increasingly held accountable for their environmental impact, and the progress in drilling technology is reflective of a broader industry shift towards sustainability.

The Martian atmosphere is composed primarily of carbon dioxide (about 95.3%), with traces of nitrogen (2.7%), argon (1.6%), and other gases. This composition, combined with the low pressure, leads to several unique environmental conditions on the planet.

The reason:
Inlet valve is not open or has silted
Suction line resistance is too high or blocked
Suction height is too high
