T/CCMA 0032-2015 Hydraulic excavator double-fed axial piston pump laboratory durability test
Basic Information
Scope
Scope: This standard specifies the technical requirements, test methods, and inspection rules for the durability test of twin axial piston pumps (hereinafter referred to as twin axial piston pumps) used in hydraulic excavators in laboratories. This standard applies to the durability test of twin axial piston pumps used in medium-sized (20–23 t) hydraulic excavators with a system working pressure ≤ 35 MPa; Main technical content: This standard specifies the technical requirements, test methods, and inspection rules for the durability test of twin axial piston pumps (hereinafter referred to as twin axial piston pumps) used in hydraulic excavators in laboratories.
