Uses

Rock drilling machine for blasting is widely used in mining roadway boring and various rock drilling operations, in addition to building sites, defence construction and quarries.
In mining and rock drilling operations, rock drilling machine for blasting is an important tool for horizontal drilling and inclined gun holes in medium-hard or hard rock, with a gun hole diameter of 34-42 mm in general and an effective and economical drilling depth of up to 5 meters. In addition, it is also widely used in tunnel boring and support operations in transport, water conservancy, hydropower and other projects.
Meanwhile, rock drilling machine for blasting is also significantly used in building sites and defence construction for performing various drilling operations. In quarries, it is often used to split rocks and improve working efficiency.
To sum up, rock drilling machine for blasting has a wide range of applications and can meet the needs of different projects and operations.

FAQ

Q: What should I do if there is a problem of impact weakness in the rock drill?

A: The cause of the failure: May be the flow or pressure is not enough, that is, the flow is not up to 90L/min, the pressure is not up to 10~16Mpa; may also be the rock drill's accumulator nitrogen pressure is not enough, or the rock drill on the mechanical connection part is not reliable, such as threaded joints loosening; may also be the use of the rock drill for a long time, the piston and the front and rear cylinder liner because of the abrasion and wear of the clearance becomes large, resulting in the impact of the part of the internal leakage excessive.
Remedy: Check the pressure and flow rate of the hydraulic system carefully and adjust the corresponding valves; check the nitrogen pressure of the accumulator and replace damaged diaphragms or seals; tighten all threaded connections with a spanner; replace worn pistons and front and rear cylinder liners.

Q: What should I do if there is no impact sound problem with rock drill?

A: The cause of the fault: May be the piston can move but can not hit the end of the braze, due to the rock drill on the mechanical connection part of the unreliable piston caused by the lengthening of the stroke; may be the piston can not move, the reason may be the reversing valve can not be reversed or the piston and the cylinder liner is stretched and burned and can not move.
Elimination measures: Tighten all threaded connections with a spanner, if there is still a problem, you need to check the status of the reversing valve and the piston and cylinder liner, and replace or grind them if necessary.

Q: Why does the rock drill leak air?

A: Reason for the fault: It may be air leakage at the joint of wind rope, or wear and tear of internal parts of the rock drill leading to poor sealing.
Troubleshooting measures: Eliminate air leakage at wind rope joints, install pressure gauges to test the wind pressure, make sure the internal parts of the rock drill are intact, and replace the worn parts in time.

Q: What should I do if the shaft thrust is too large?

A: Cause of trouble: The air leg may not work properly and the thrust force is too large, which causes the body to jump back.
Troubleshooting measures: Adjust the installation angle of the air leg, check whether the seals of the various parts of the air leg are intact, and make sure that the air leg is flexible in its expansion and contraction.
These faults and their elimination methods can help users to better maintain and use YT28 rock drill, to ensure its normal operation and extend its service life.
