20 skills of diamond dressing tools

The rock drill is a kind of simple, convenient and economic driving machinery, machine is an important quarry stone, which belongs to the impact of equipment, at the same time to oil and gas assisted with the use of a variety of media, on the one hand on the work of the equipment reliability and safety put forward higher requirements; on the other hand, but also to the operation of the equipment and the maintenance of certain difficulties. Use and maintenance of scientific drilling machine, not only to ensure the production safety, prevent accidents is of great significance, but also has important significance to improve the equipment performance, production efficiency, working life.

Preparation before starting

1, the purchase of new drilling machine, coated with antirust grease viscosity inside the large, clear must be removed before use. When reloading, the moving parts of the table Mina to be coated with lubricating oil. After installed will drill through compressor pipeline, open wind operation, check the operation is normal.

2, automatic lubricator grease, commonly used lubricating oil for 20#, 30#, 40# oil. Containers of lubricating oil should be clean, cover, prevent rock powder and dirt into the oiler.

3, check the location of the wind pressure and water pressure. The wind pressure is 0.4-0.6MPa, wind pressure is too high will speed up the damage of mechanical parts, low drilling efficiency and can reduce the corrosion of mechanical parts. The pressure is generally 0.2-0.3MPa, high pressure water will be poured into the machine internal damage lubrication, reduce drilling machine efficiency and the corrosion of mechanical parts; too low flushing effect bad.

4, the use of Qianzai whether meet the quality requirements, prohibited the use of substandard qianzai.

5, the wind pipe connected to drill, will blow off the dirt should be deflated. The water pipe, the water to clean the joints at the dirt, the wind pipe and water pipe must be tightened, in order to prevent falling off wounding.

6, the drill shank is inserted into the head, forced the clockwise rotation of the drill. If we can not move, that the machine has jammed phenomenon, should be timely treatment.

7, tighten the bolts, open the air to check the operation of the propeller, running normally to start work.

8, rail type drilling machine rack should be the pillar, and check the running condition of the propeller, air leg drill and have to drill to check the gas leg flexibility etc..

9, the hydraulic drill hydraulic system should require a good seal, to prevent contamination of hydraulic oil, hydraulic oil to ensure a constant pressure.

Note when working

1, his eyes should be rotated slowly, after the hole depth is up to 10-15mm, and then gradually into full operation. In the process of drilling, according to the design of the drill hole straight forward, and is located in the center of the hole.

In 2, when the drive shaft thrust drilling should be reasonable. Axial thrust is too small, the machine size of vibration increases, the drilling efficiency is reduced; axial thrust greatly, Qianzai tightening the fundus, the machine operates under the overload, premature wear parts, the drilling speed slows down.

3, rock drill jamming, axial thrust should be reduced, you can gradually become normal. If not, stop immediately. First use the wrench slowly rotating the drill rod, and then open the pressure Qianzai slowly rotating, forbidden processing with beating rod method.

4, often observe the powder situation. Fly is normal, the mud along the hole slowly outflow; conversely, a strong blow hole. If you are still valid, should check the status of drill hole and shank, then check the water needle, replace the damaged parts.

5, to observe the oil reserves and oil, adjust the injection quantity. Oil free operation, easy to premature wear parts. When the lubricating oil is too much, it will cause the pollution of the working face.

6, the operation should pay attention to the sound of the machine, observe its operation, find problems, timely processing.

7, pay attention to the drill working state, abnormal timely replacement.

8, the operation of stoper should pay attention to prevent the volume of air leg drill, swing up and down the accident. Air leg support points to be reliable. When holding the machine can't ride more tight gas leg to prevent the damage of machine.

9, attention should be paid to the rock, avoid perforation along bedding, joints and cracks, forbidden residual eyes, always observe the risk without roof and side.

10, to effectively use the opening function. In the drilling process, there is an important part of the hole, the hole is used to reduce the impact pressure and fixed propulsion pressure to complete the. Push the pressure should be as small as possible, in order to facilitate the opening of very large rock surface, but also to avoid the bending of the drill pipe.
