Product Description

This main hydraulic pump designed for the E313B excavator serves as the power core of the entire hydraulic system, directly determining the excavation force, action response speed, and overall operational stability of the equipment. The E313B is a medium-sized engineering equipment widely used in urban infrastructure, earthwork excavation, site preparation, municipal renovation, and other various conditions. It has high requirements for the reliability and response sensitivity of the main pump.

The pump body shell is formed by a single piece of high-strength cast iron, which undergoes aging stress relief treatment. The shell has high strength, excellent resistance to impact and high-pressure deformation, and can adapt to the complex environment of construction sites with high dust, large temperature differences, and frequent start-stop operations. The internal core friction pairs such as the cylinder body, piston, flow distributor plate, and return plate are made of high-hardness wear-resistant materials, which are precisely ground and processed to strictly control the part clearance, effectively reducing internal volume leakage and ensuring that the equipment maintains a high level of efficiency for long-term continuous operation. The pump body is equipped with the original specification flow pressure regulating control valve group, which can dynamically adjust the output flow and system pressure in real time according to external loads. Heavy-load operations provide sufficient high pressure, while light-load operations automatically optimize power output, effectively improving hydraulic faults such as stuck machine, slow action, insufficient digging force, and insufficient pressure that often occur in the E313B model, balancing operational performance and fuel consumption performance.
