Advanced Liyuan Axial Piston Pump Solutions for the Shandong Feici Xiangde 4200 Drilling RigIn
the high-stakes environment of deep-hole mining and geological
exploration, hydraulic reliability is not just an option—it is the
lifeline of operations. For the robust Shandong Xiangde ZDY4200LPS Crawler Hydraulic Drilling Rig, the heart of its performance lies in its hydraulic power unit. Shandong Feici Engineering Machinery Co., Ltd. delivers a premier upgrade and replacement solution featuring genuine Liyuan (Avic Liyuan) Axial Piston Pumps, engineered to maximize torque, ensure stability, and extend service life in the harshest underground conditions. The Challenge: Demanding Performance in Deep Coal SeamsThe
Xiangde 4200 series rig is designed for deep-hole drilling (up to 420
meters) in soft rock and coal seams, often requiring high torque (up to
5600 N.m) and precise control for anti-outburst measures. Standard
hydraulic components often struggle with:
To counter these challenges, Shandong Feici integrates Liyuan’s heavy-duty variable displacement axial piston pumps as the core main and auxiliary pump solution. The Solution: Liyuan Axial Piston Pump TechnologyShandong Feici supplies a matched pair of Main and Auxiliary Pumps
specifically calibrated for the Xiangde 4200 architecture. Leveraging
Liyuan’s decades of aerospace-derived hydraulic manufacturing expertise,
these pumps offer: 1. Unmatched High-Pressure ResilienceDesigned for continuous operation at pressures exceeding 35-40 MPa,
the Liyuan piston pumps utilize hardened cylinder blocks and
precision-ground pistons. This ensures the ZDY4200LPS maintains
consistent rotary torque and feed force, even when encountering
unexpected geological hardness. 2. Dual-Pump Synergy (Main & Auxiliary)
3. Enhanced Volumetric EfficiencyWith volumetric efficiency ratings often surpassing 95%,
these pumps minimize internal leakage and heat generation. This
translates to lower fuel consumption for the rig’s diesel engine and
reduced cooling load, critical for confined underground tunnels where
ventilation is limited. 4. Durability in Abrasive EnvironmentsMining
environments are rife with contaminants. The Liyuan pumps supplied by
Shandong Feici feature advanced sealing technologies and wear-resistant
materials that tolerate minor fluid contamination better than standard
imports, reducing downtime for maintenance. Why Choose Shandong Feici for Your Hydraulic Overhaul?Shandong
Feici Engineering Machinery is not merely a parts distributor; we are
hydraulic system specialists. Our commitment to the Xiangde 4200
platform includes:
