Mud Pump Liner-Ceramic Liner

Mud hog pump is the “heart” of the oilfield drilling system, and mud pump liner is an important vulnerable parts of mud pump fluid end. The service time of oil drilling mud pump will be directly affected by service time of mud pump liner.

Mud pump cylinder liner will contact with the high-temperature, high-pressure gas directly, and mud pump piston ring makes a high-speed reciprocating motion on the surface of the liner, which determines that the mud pump liner not only has sufficient strength and rigidity, but also must withstand high temperature, corrosion resistance and wear resistance.

Ceramic Liners are made of a ceramic inner sleeve and a forged steel outer shell. The service life of ceramic liners is about 4000 to 10000 hours, the minimum time is at least 2000 hours, which is a lot more than bi-metal liners. Because of the phase transformation toughen technology, the ceramic liners have the features of wear-resistance, erosion-resistance, high-pressure-resistance, high hardness and strength. Zirconia type and Alumina type are common type of ceramic sleeve. Compared with Alumina type, Zirconia type liners have better toughness properties and a much longer service life. Piston wear and water consumption for lubrication can be reduced as well.
