Mud Pump Components and Spare Parts Abrasion resistance
One of the hydraulic side parts of the mud pump
There are several types of mud pump cylinder liner: single metal cylinder, double metal cylinder liner, ceramic cylinder liner, nickel-base alloy cylinder liner.
Single metal cylinder liner
Single metal cylinder liner is after carburizing and high frequency treatment, hardness can reach HRC58-62, with a high degree of finish, wear resistance, corrosion resistance, long using life, characteristic, suitable for use in a polite corrosive slurry.
Double metal cylinder liner is one of the most widely used and is also one of the most used mud pump hydraulic end accessories. Bimetal liner contact the hot forging high wear coat and high chrome wear-resisting corrosion within the set of strengths, coat choose quality carbon steel hot pressing molding, inner sleeve to choose high chromium cast iron centrifugal casting and become, meantime coat has higher than 900000 psi tensile strength, inner sleeve through the hardness after heat treatment more than HRC62, can accept 7000 psi mud pressure, lubrication its appearance as a mirror, the inner hole size tolerance strictly, normal use life can reach more than 800 hours.
Nickel-base alloy cylinder liner
Follow the progress of science and technology, has developed the adopting new materials made of nickel base alloy cylinder liner, the skills for the alloy material coated on the inner wall of the cylinder liner, using vacuum sintering skill, to form the alloy sintered layer 1.5 mm, the sintering layer data of high function of rare earth nickel-based alloy powder material increase a micron grade cemented carbide material, sinter layer evenly scattered in micron level of high wear-resistant hard points, effectively improve the function of all the wear resistance of sintered layer, together for alloy arrangement and its tiny, not attack arrange spalling, etc. Because the powder form is a good alloy sintering layer, the contact strength is good, the sintering layer rockwell hardness reaches HRC: 60-64.
Ceramic cylinder liner is the three main information system of zirconia, zirconia toughened alumina (ZTA) and high function a-99 alumina ceramics. The original data to choose high purity nanometer zirconium oxide and alumina powder, leading by cold pressing skills a molding, high temperature sintering, assembling, eventually the high precision grinding and polishing, has the very high bending, tensile strength, high fracture toughness and resistance to acid and alkali corrosion function.
