Assembly and method for preloading a cylinder liner and cylinder liner cartridge assembly

摘要

Apparatus and methods for applying radial compressive stress pre-loading to a cylinder liner (20) are disclosed. A cylinder housing (10) is attached to a pump, and a cylinder liner (20) is disposed within the cylinder housing (10). A fluid inlet (16) in fluid communication with an annular space (30) between the cylinder housing (10) and cylinder liner (20) is disposed on the cylinder housing (10). The annular space (30) is filled with pressurizing fluid through the fluid inlet (16), which creates radial compressive stress pre-loading on the cylinder liner (20).
