Danfoss axial piston pump for tunneling machines
Danfoss axial piston pumps for road headers are essential components in the hydraulic systems of road headers, providing reliable power output for various working operations. Here are some common Danfoss axial piston pumps suitable for road headers and their characteristics:
D1P Series Open-Circuit Axial Piston Pumps
The D1P series is designed to meet the tough pressure and flow demands of variable-displacement open-circuit applications. It is built to withstand harsh conditions in heavy-duty mobile machines, including road headers. These pumps have displacements up to 260 cm³, maximum working pressures of 350 bar, input speeds up to 2,500 rpm, and a variety of control options, such as mechanical torque control (MTC) and electronic displacement control (EDC). They also feature angled piston bores, spherical valve plates, and roller cradle bearings for high performance and durability.
Series 45 Open-Circuit Axial Piston Pumps
Take the model with the item code 83099586 as an example. It belongs to the E-frame of the Series 45 open-circuit axial piston pumps. It has a displacement of 100 cc/rev, a maximum continuous rated pressure of 310 bar, and a control type of pressure-compensated/load sensing. The pump has a clockwise rotation, a splined shaft with 14 teeth, and a SAE-C 4-bolt flange for the front flange.
90R/90L Series Closed-Circuit Axial Piston Pumps
The 90R/90L series is a closed-circuit axial piston pump designed by Danfoss for high-demand hydraulic systems. It is characterized by high pressure (up to 48 MPa), large displacement (common displacements include 90R055, 90R075, 90R100, 90R130, etc.), and flexible control methods (electrical control, hydraulic control, mechanical manual control). Although it is a closed-circuit pump, it can also be applied to some road header hydraulic systems that require high-pressure and stable power output.
These Danfoss axial piston pumps, with their excellent performance and reliable quality, can effectively ensure the stable operation of road headers and improve work efficiency.
