Submarine Hammer Drilling An Insight into Techniques and Applications
The Rising Demand for Drilling Equipment A Comprehensive Overview
Mars has an incredibly thin atmosphere, with surface pressure averaging about 0.6% of Earth’s. This is equivalent to about 610 Pascals compared to Earth's 101,325 Pascals at sea level. This stark difference is largely due to Mars' lower gravity and lack of a magnetic field, which makes it harder for the planet to retain gases essential for a thicker atmosphere.
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
