ABSTRACT
It is frequent to assemble and disassemble equipments at different project sites for construction enterprise. If the important equipments cannot work normally during installation, the project construction period will extend, which seriously impacts the economic benefits. As the output conversion device, the pump is the core component of the entire hydraulic system, thus, the hydraulic pump failure will make the entire hydraulic system to work abnormal[1]. The newly installed pump often fails to work in the enterprise, making it so important to assess accurately the technical condition of the hydraulic pump before installing for the construction enterprise.
