1. Advantages of mud pump ceramic cylinder liner:
As the scope of human exploration of global oil and gas resources continues to expand and become more and more severe, a large number of metal cylinder liners are frequently replaced and it is difficult to ensure the high pressure and wear requirements of the drilling rig.Ceramic cylinder liner is made of three major types: zirconia, zirconia toughened alumina (ZTA), and high-performance A-99 alumina ceramic Material system. Its raw materials are made of high-purity nano-zirconia and aluminum oxide powder, which are formed in one step through advanced cold pressing technology, high-temperature sintering, assembly, and finally high-precision grinding and polishing. It has high flexural strength, tensile strength, and high durability. Fracture toughness and acid and alkali corrosion resistance.
The mud pump cylinder liner is the "heart" of the oilfield drilling system, and the mud pump cylinder liner is an important and easy-to-wear component of the fluid end of the mud pump. Therefore, the life of the mud pump cylinder liner is directly Affects the life of the mud pump. Since the working surface of the cylinder liner is in contact with high-temperature and high-pressure gas, the piston ring reciprocates at high speed on its surface. This determines that the cylinder liner must not only have sufficient strength and rigidity, but also must be resistant to high temperatures, corrosion, and wear. damage. "Ceramic cylinder liner" can meet the needs of these environments, so it is widely used!
