Pneumatic impact drill mining pneumatic impact drill manufacturer

Description :

　　The QCZ-1 multi-purpose pneumatic drilling rig is a lightweight and agile small pneumatic tool with the functions of impact rotation, simple impact, and clockwise rotation. Pneumatic explosion-proof with no sparks and good safety performance.

　　Scope of use of pneumatic impact drill

　　Pneumatic impact drills are mainly used for installing pipelines, setting up power lines, installing anchor bolts on components such as rocks, brick walls, concrete, chemical plants, refineries, buildings, heavy industries, tunnels with hazardous and humid gases, underwater and narrow space operations; Especially in high gas explosion-proof mines, pneumatic explosion-proof without sparks can better reflect its safety.

　　Structure and working principle of pneumatic impact drill

　　Pneumatic impact drill is composed of handle body, pressure handle, cylinder, head, push rod, etc. The compressed air enters the cylinder through the connecting pipe joint of the trachea and the pressure handle for air volume adjustment, and then is adjusted by the push rod to achieve impact rotation or simple impact, thus achieving the effect of impact or rotation.

　　Instructions for using pneumatic impact drill

　　1. Before starting work, it is necessary to add lubricating oil. Simply unscrew the screw plug on the handle to add oil.

　　2. Blow out the air duct before connecting it to the machine.

　　3. It is advisable to use an air pressure of 0.5-0.6Mpa.

　　4. The thrust should be appropriate during rock drilling. Excessive thrust reduces the rotation speed of the drill rod, affecting work efficiency. Insufficient thrust and machine jumping also affect efficiency and can easily damage drilling tools.

　　5. The thrust can be adjusted by the grip strength of the pressure handle.

　　Precautions for Pneumatic Impact Drilling

　　1. Personnel using the QCZ-1 drilling rig must be familiar with the performance, structure, operation methods, and safety precautions of the rig.

　　2. The compressed air used must be clean.

　　3. It is necessary to ensure the oil mist lubrication of the gas motor in the drilling rig, and the no-load operation time cannot exceed 60 seconds.

　　4. The drill bit used should be sharp.

　　5. The following situations are prohibited from use: abnormal sound inside the gearbox, such as collision sound, etc.

　　6. If there are any problems with the drilling rig, please do not dismantle it yourself and return it to the factory for timely processing. Thank you for your cooperation.

　　Maintenance and repair of pneumatic impact drill

　　1. Regularly check whether there is oil in the oil mist device and ensure the lubrication of the air motor.

　　2. To ensure the cleanliness of compressed air, in order to avoid wear and tear on the air motor and reduce its service life.

　　3. Regularly check the wear of rubber seals.

　　4. Replace severely worn bearings and gears, clean oil stains, and replace with new lubricating oil.

　　5. After use, the drilling rig must be cleaned of dust, oil stains, and other dirt, and the fastening of screws and nuts should be checked.

　　6. After inspection and cleaning, the drilling rig should be properly stored in a dry location to prevent rusting of the parts.

　　7. Problems must be promptly addressed or parts replaced before use.

　　8. If you feel tired or the drilling speed slows down during drilling, you should check the drill bit. It may have been worn dull and needs to be re sharpened or the air pressure is insufficient.

　　9. Please adjust the serial number to push the push rod when impact is required.

　　10. Try to avoid empty running of the machine as much as possible to prevent damage to the components.

　　11. The drilling tool must be loaded and unloaded by pressing the sliding sleeve on the upper head, but cannot be pulled out of the clamp.
