Automatic Control
1. Overview
Engineered for extreme deep water applications, the WQS Series delivers unmatched pressure resistance up to 100m submersion and exceptional adaptability to water level fluctuations exceeding ±50m amplitude. Its reinforced structural design, validated through advanced flow diagnostics and rigorous testing, enables reliable operation in media containing abrasive solid particles (up to 50mm diameter). Key innovations include wear-resistant tungsten carbide/silicon carbide coatings, anti-clogging impeller geometry, and dual mechanical seals ensuring leak-free performance under continuous high-pressure conditions. The pump supports full-head operation across variable flow rates (50–300 m³/h) and integrates automated control systems for unmanned deployment in applications demanding deep submersion, heavy sediment loads, and rapid water level changes.
The product is successfully applied for drainage purpose at the world largest dam project - Three Gorges Dam, which proves its reliability for highly sensitive applications demanding zero downtime.
2. Application
● For larger changes in water level, that is, the larger amplitude head on, the pump head with all the safe use of features in the large and small flow areas are set.however.
● For the depth of flood situations, the pump can withstand water pressure safe use of 100m.
● For small flow and high head sewage occasions, especially for long-distance transport of sewage.
● Applicable to the higher silt content in the occasion, the pump characteristics of both the slurry.
● With high reliability features, especially for a major, major projects.
3. Characteristics
● High-Head and Deep-Submersible Design: Adoption of multi-stage impeller configuration or variable frequency speed regulation technology to accommodate long-distance water transfer requirements. The motor-pump integrated design ensures adaptability to complex operating conditions.
● Automated Control and Intelligent Monitoring: Auto start-stop functionality and remote monitoring capabilities, integrated with protection functions for temperature, overload, and vibration. Real-time feedback on operational status and early warning alerts.
● Wear-Resistant and Corrosion-Resistant Materials: Optimized material selection for enhanced wear resistance and acid/alkali corrosion resistance. Dual mechanical seal design ensures leakage prevention.
● High Efficiency and Energy Saving: Variable frequency speed control technology, optimized flow channel design for reduced flow resistance, and improved operational efficiency.
