Product Description
Main Pump Assembly for ZDY12000LD Directional Drilling Rig
Product Overview: This high-performance main pump assembly is specifically engineered for the ZDY12000LD series fully hydraulic directional drilling rigs. The assembly features a robust triple-pump configuration, utilizing the Rexroth A11VLO190 high-pressure variable piston pump as the primary stage, coupled with A10VO71 and A10VO28 series pumps. This integrated system serves as the core power source for the rig’s rotation, feeding, and tramming systems, ensuring high reliability and massive torque output in demanding underground mining environments.
Key Technical Advantages:
High-Efficiency Triple Integration: Designed to meet the heavy-load requirements of the ZDY12000LD, using a precise 190cc + 71cc + 28cc flow distribution. The primary A11VLO190 pump delivers a rated pressure of 350 Bar, supporting the high-torque rotation required for large-diameter drilling.
Superior Self-Priming (L Spec): The A11VLO190 main pump offers exceptional self-priming traits, ensuring full displacement even with varying oil viscosities or restricted inlet conditions, preventing power fluctuations during drilling operations.
Precise Power Modulation: Equipped with advanced Constant Power and Load Sensing (LS) controls, the assembly automatically adjusts output based on hole depth and formation hardness, effectively preventing engine or motor overload.
Mine-Grade Durability: Optimized for underground coal mine conditions (high dust/humidity), featuring reinforced seals and heavy-duty swashplate designs. This significantly extends the Mean Time Between Failures (MTBF) during continuous directional drilling.
Detailed Models & Parameters:
Compatible Equipment: ZDY12000LD Directional Drilling Rig.
Primary Pump Model: A11VLO190 (Rated 350 Bar / Peak 400 Bar).
Secondary Pump Model: A10VO71 (Matched for auxiliary control).
Tertiary Pump Model: A10VO28 (Compact design for pilot or cooling systems).
Total Displacement Mix: 190 cm³/rev + 71 cm³/rev + 28 cm³/rev.
