2. Pressure The pressure generated by the mud pump must be enough to overcome the hydrostatic pressure of the column of drilling fluid in the well and provide the necessary pressure at the drill bit. The pressure can be calculated using

1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.

Before each day's operation, refill the 29 grease points with grease.

Mars, often referred to as the Red Planet, has long fascinated scientists and space enthusiasts alike. One of the most intriguing aspects of Mars is its atmosphere, which is characterized by low pressure compared to that of Earth. Understanding the implications of low atmospheric pressure on Mars is crucial for various fields, including planetary science, astrobiology, and the future of human exploration.

The reason:
The suction pipe is not filled with water
Blocked suction line or inadequate valve opening
The inlet pipe of the pump, the meter or the stuffing box are serious
