What is the function of a mud pump
2024-11-02Mud pump is a device used to transport liquids containing solid particles such as mud. Its main functions are as follows: 1、 In the field of drilling Transporting Mud: During geological drilling, the prepared mud is transported into the borehole to cool the drill bit, carry rock debris, and balance formation pressure. The mud pump generates a certain pressure to circulate the mud in the bo
