How to Maintain a Pneumatic Rib Drill?

I. Daily Maintenance Points

1. Cleaning and Maintenance

After each use, wipe the machine body clean of dust and oil stains with a soft cloth to keep the equipment clean.

Regularly check the oil-water separator to ensure the compressed air is dry and prevent moisture from entering the drill.

2. Component Inspection

Drill Rod and Drill Bit: Before use, check if the drill rod is straight, the drill bit edge is sharp, the alloy blade is secure, and the joint threads are unworn.

Air and Water Lines: Ensure the air line connection is secure and leak-free; ensure the water line is unobstructed and avoid blockages.

Oil Filler: Maintain the oil level at approximately 200ml, leaving a 10% cavity in the transparent housing to prevent oil shortage.

3. Trial Run

Turn off the air and water switches and repeatedly pull the trigger to check if the switches are flexible and reliable.

Turn on the air and water switches, briefly pull the trigger, listen for normal sound, and observe if the operation is smooth.

II. Regular Maintenance (Every 3-6 Months)

1. Deep Cleaning

Remove mud and dust from the equipment to keep it clean.

Inspect the spindle threads and apply grease to prevent rust.

2. Component Replacement

Inspect gears, bearings, silencers, and other components. Replace any severely damaged parts immediately.

Inspect valve body seals and springs. Replace any damaged parts.

3. Professional Inspection

Have the equipment inspected at a professional maintenance center every 3-6 months to ensure stable performance.

III. Safe Operating Procedures

1. Protective Measures

Operators must wear masks and goggles. Safety ropes must be worn when operating platforms exceeding 2 meters.

Touching the drill rod or drill bit with hands or gloves while the drill is rotating is strictly prohibited.

2. Operational Prohibitions

Using the drill at pressures exceeding the specified limits is strictly prohibited.

The machine must be stopped immediately when dealing with a stuck drill bit to prevent injury.

IV. Parts Selection and Replacement

1. Drill Rods

42*1000mm Water Probe Drill Rod: Suitable for drilling coal, borehole diameter 42mm, price 16.50 yuan.

φ50mm Spiral Drill Bit: Suitable for pneumatic handheld drills with stand support, price 132.00 yuan.

2. Replacement Cycle

Replace drill rods and drill bits periodically according to usage frequency and wear condition to avoid affecting drilling efficiency and safety due to component damage.

V. Troubleshooting

1. Common Problems

Drill cannot start: Check if the air hose connection is secure and if the lubricator has sufficient oil.

Low drilling efficiency: Check if the drill bit is worn and if the drill rod is straight.

Abnormal noise: Check if the gears and bearings are damaged.

2. Troubleshooting Methods

Based on the fault symptoms, check and troubleshoot according to the maintenance manual. Contact professional maintenance personnel if necessary.
