Industry Background Introduction

Excavators are one of the most common construction equipment in the engineering machinery industry, and are used in infrastructure, road engineering, mining, water conservancy and hydropower, municipal construction and other fields. The core power source of its operation comes from the hydraulic system. The hydraulic pump, hydraulic motor, multi-way valve, hydraulic cylinder and other components work together to complete complex excavation, lifting, walking and rotation actions.

Decreased Efficiency Of Hydraulic Pumps

Problem manifestation:

Slow excavation and arm lifting, weak equipment output

Root cause:

Serious wear of the internal matching of the variable piston pump, reduced volumetricefficiency
