In the coal mine drilling equipment, spiral drill pipe is the most common use, how to make the use of spiral drill pipe life growth, this is our long-term consideration of the need. The way to improve the life of the spiral drill pipe is mainly from the material of the spiral drill pipe, the consumption process, the use of various aspects such as comprehensive thinking, focusing on the treatment of thin links, from time to time to improve and perfect the process request. The following two points are the direction to improve the life of the spiral drill pipe. 1, from the structure of the rock drilling machine to stop from time to time to improve, for example, from the pneumatic rock drill one big piston and the other small piston to the hydraulic rock drill equal diameter cylindrical piston, in ensuring
Increase spiral drill pipe life?
In coal mine drilling equipment, spiral drill pipe is the most common use, how to make the use of spiral drill pipe life growth, this is what we need to consider for a long time. The way to improve the life of the spiral drill pipe is mainly from the material of the spiral drill pipe, the consumption process, the use of various aspects such as comprehensive thinking, focusing on the treatment of thin links, from time to time to improve and perfect the process request. The following two points are the direction to improve the life of the spiral drill pipe.
1. From the structure of the rock drilling machine to stop the improvement from time to time, for example, from the piston of the pneumatic rock drill with one large end and the other small end to the equal diameter cylindrical piston of the hydraulic rock drill, the waveform of the rock drilling stress wave is changed while ensuring the rock drilling speed to increase from time to time, and the damage stress acting on the spiral drill pipe is reduced.
2. Improve the comprehensive mechanical properties of the spiral drill pipe material and the consumption process of hollow steel, and minimize the internal and external defects of the spiral drill pipe to ensure that the spiral drill pipe has high quality and service life. Of course, the correct operation and management of rock drilling, the good cooperation between the front tools and their respective processing accuracy are also the fundamental conditions to ensure the life of the spiral drill pipe.
There are also many varieties of spiral drill pipes, and their interfaces are different. The commonly used spiral drill pipe should be the spiral drill pipe. The application of this kind of spiral drill pipe is relatively common. The service life of this kind of spiral drill pipe is also relatively good. It can be applied to the mining of various mines. Due to the complex stress state and harsh environment, the practical working life of spiral drill pipe is only a few minutes to tens of hours. With the development of rock drilling machinery to high power and high frequency, it is urgent to improve the life of spiral drill pipe in an all-round way.
Choose high-quality drilling pipe, please identify the beneficial mining drilling tools.
