Description

The liner of the mud pump is an important and easily worn part of the hydraulic end of the mud pump. The service life of the liner of the mud pump directly affects the service life of the mud pump. When the cylinder liner works, the piston makes a high-speed reciprocating motion on its surface, which determines that the cylinder liner must not only have sufficient strength and rigidity but also be resistant to high temperature, corrosion, and wear. Our main products are single metal, bimetal, and ceramic cylinder liners, with reliable and stable quality and preferential prices.

Single metal cylinder

After carburization and high-frequency treatment, the hardness of the single metal cylinder liner can reach HRC58-62. It has the characteristics of high finish, wear resistance, corrosion resistance, and long service life. It is suitable for use in milder corrosive mud.

Bimetal cylinder liner

Bimetal cylinder liner combines the advantages of hot forged high wear outer sleeve and high chromium wear-resistant and corrosion-resistant inner sleeve. The outer sleeve is made of high-quality carbon steel by hot pressing at one time, and the inner sleeve is made of high chromium cast iron by centrifugal casting. The outer sleeve has a tensile strength higher than 900000psi, and the hardness of the inner sleeve after heat treatment reaches more than HRC62, which can withstand 7000psi mud pressure, and the normal service life can reach more than 800 hours.

Ceramic cylinder liners

Ceramic cylinder liners are made of zirconia, zirconia toughened alumina (ZTA), and high-performance a-99 alumina ceramics. Its raw materials are high-purity nano zirconia and alumina powder, which are formed by an advanced cold pressing process, high-temperature sintering, assembly, and finally high-precision grinding and polishing. It has high flexural and tensile strength, high fracture toughness, and acid and alkali corrosion resistance. the normal service life can reach more than 4000hours.
