The high-pressure mud pump is the heart of the oilfield drilling system. It is responsible for transporting mud downhole and completing the transfer of materials and energy. The cylinder liner is a key component of the mud pump. Since the cylinder liner has been used for a long time Relatively reciprocating motion under high pressure, so the cylinder liner is an easy-to-wear part of the mud pump. Traditional cylinder liners are made of metal materials, which have poor wear resistance and short service life! With the continuous expansion of the scope of human exploration of global gas and oil resources, it gradually extends towards deserts, wastelands, and deep seas. Wells are getting deeper and deeper, and their conditions are getting worse. As the situation gets worse and worse, a large number of metal cylinder liners are frequently replaced, making it difficult to meet the high pressure and strong wear requirements of the drilling rig. Our company produces zirconia ceramicsZirconium Oxide Ceramic strong>, high performance95-99.99 alumina ceramicMaterial systemCeramic cylinder liner.
Ceramic cylinder linerThe raw materials are made of high-purity nano-zirconia and alumina powder, which are formed in one step by advanced cold pressing process, sintered at high temperature, assembled, and finally Made by high-precision grinding and polishing. This ceramic cylinder liner product has high wear resistance, high temperature resistance, high fracture toughness and acid and alkali corrosion resistance.
Compared with metal cylinder liners, ceramic cylinder liners have the following advantages:
1. The service life is 5-10 times longer than that of metal cylinder liners;
2. It has the advantages of wear resistance, corrosion resistance, high pressure resistance, high temperature resistance, high strength and high hardness;
3. Reduce the transportation costs, maintenance costs, labor costs, storage costs, etc. of drilling work;
4. Ceramic cylinder liners are more tough, have longer service life, save lubrication water, and reduce piston wear.
