FAQ：
1.What should I do if the air compressor malfunctions and cannot provide enough high-pressure air?
First check if the power supply and pipeline connections of the air compressor are normal, then check if the air filter is clogged and if the pressure regulating valve of the air compressor is set correctly. If there is a malfunction in the internal components of the air compressor, it is recommended to have professional maintenance personnel carry out repairs and replace damaged parts in a timely manner to ensure the normal operation of the air compressor and provide stable high-pressure air for the impactor.
2.What is the drilling speed of a down the hole drilling rig?
The drilling speed is influenced by various factors, such as rock hardness, drilling diameter, drilling rig power, etc. In rocks of general hardness, the drilling speed may be around 0.5-2 meters per minute. But in harder rocks, the speed will correspondingly decrease.
3.How to choose a drilling rig?
We suggest that you choose the configuration based on actual engineering requirements, such as rock hardness, aperture depth, construction environment, etc. We can provide you with a solution.
