As a drilling equipment that plays a key role in various engineering operations, the pneumatic 350 drilling rig is widely used in mining, geological exploration, construction and other fields due to its unique power source and performance characteristics. In short, the pneumatic 350 drilling rig plays an important role in many engineering fields with its unique advantages. Proper operation and maintenance can ensure its efficient and stable operation, providing strong support for the smooth progress of various engineering operations.

• Portability: The overall size is small and lightweight, making it easy to transport and transfer between different work sites. Some models are also equipped with mobile wheels or tracked chassis, further enhancing their mobility in complex terrains, enabling them to quickly reach the work position and save preparation time.
• Overload protection: The pneumatic drive mode comes with overload protection features. When encountering excessive resistance during the drilling process, such as hard rocks or foreign objects, the pneumatic motor will automatically reduce its speed or stop running, avoiding equipment damage due to overload, effectively extending the service life of the equipment, and reducing maintenance costs.
• Strong adaptability: It can adapt to various types of drill rods and drill bits, and can choose the appropriate drilling tool combination according to different drilling requirements and geological conditions. Meanwhile, for rocks and geological structures of different hardness, adjusting parameters such as compressed air pressure, propulsion speed, and rotation speed can also ensure better drilling results.
• Efficient operation: Under suitable working conditions, it can achieve high drilling speed and improve operational efficiency. For example, in some mining projects, the drilling efficiency has significantly improved compared to traditional drilling equipment, providing strong support for large-scale mining operations.

• Equipment inspection: Before starting work, it is necessary to carefully inspect all components of the drilling rig to ensure that they are securely connected and free from looseness or damage. Check if the tracheal connection is tight and if there is any air leakage; Check if the oil level in the oil injector is sufficient to ensure that the drilling rig is working in a well lubricated state.
• Air source requirements: Ensure that the compressed air pressure and flow provided by the air compressor meet the working requirements of the drilling rig. Low pressure can lead to insufficient power of the drilling rig, affecting drilling efficiency; Excessive pressure may damage the pneumatic components inside the drilling rig. Generally speaking, the working pressure range of the pneumatic 350 drilling rig is between 0.4-0.63MPa.
• Drilling operation: When drilling, the speed should not be too fast. First, slowly drill a certain distance (about 30 millimeters), then open the water valve (if wet drilling is required), and gradually increase the speed to enter normal drilling operation. During the drilling process, it is necessary to increase the manual thrust at a constant speed (if the drilling rig is operated manually) to avoid problems such as slow drilling speed, stuck drill, bent drill rod, or damaged drill bit caused by uneven thrust.
• Safety protection: Operators must wear personal protective equipment such as safety helmets, goggles, earplugs, etc. to prevent damage to the body caused by debris splashing, noise, etc. during the drilling process. It is strictly prohibited to use bent drill rods, and it is strictly forbidden to hold the drill rods with hands during drilling to avoid accidents.
• Equipment maintenance: After the operation is completed, first close the water valve (during wet drilling), and then let the drilling rig run idle for a few minutes to remove internal moisture and prevent rusting. Regularly check whether the bolts of the drilling rig are loose and tighten them in a timely manner; Replace worn parts to maintain good performance of the drilling rig. Place the drilling rig in a safe place to avoid damage such as blasting, compression, rolling, and collision.
