Improve slurry purification – The sand content in the slurry is the main factor affecting the lifespan of the vulnerable components in slurry pumps. According to relevant information, when the specific gravity of the mud reaches 2.25, the lifespan of the piston is only 1/10 of that when water is used as the working fluid. Therefore, it is very important to strengthen slurry purification by equipping drilling rigs with high-frequency vibratory screens, sand removers, mud removers, and degasers. 2. Create favorable suction conditions. Good suction conditions ensure the pump’s suction efficiency, thereby reducing vibrations caused by shock loads resulting from uneven displacement, and thus extending the lifespan of vulnerable components. The specific requirements are as follows: a. Where conditions permit, using a raised mud tank allows the use of the gravity of the liquid to create conditions for suction-based pouring. b. Use large-diameter, short, and straight suction pipes to reduce harmful inertial effects and head losses. c. Try to avoid right-angle and curved pipes, as these increase fluid resistance.
