FAQ;

1. Special Working Conditions & Adaptation

Q1: What solutions are available for the pump when used in high-altitude areas (≥3000m above sea level)?

A5: High-altitude adaptation focuses on solving problems caused by low air pressure: ① Suction performance optimization: Reduce the suction height to ≤300mm (from 500mm at low altitude) and use a larger-diameter suction hose (inner diameter ≥30mm) to reduce flow resistance; ② Motor adaptation: Select a high-altitude motor with power increased by 10% (e.g., 40kW instead of 37kW) to compensate for reduced motor efficiency due to thin air; ③ Cooling enhancement: Replace the air-cooled oil cooler with a water-cooled type (e.g., Rexroth MCS 025) because high-altitude air has poor heat dissipation capacity; ④ Seal check: Regularly inspect the shaft seal for air leakage (low air pressure may cause external air to enter the pump), and retighten the seal pressing plate if necessary.

Q2: How to handle the pump’s operation in systems with frequent start-stop cycles (e.g., construction elevators, 20-30 starts per hour)?

A6: For frequent start-stop scenarios, take the following measures: ①Lubrication improvement: Install a pre-lubrication pump (Rexroth MPP 012) that activates 3 seconds before the main pump starts to ensure the piston and swashplate are lubricated; ② Seal protection: Replace the standard shaft seal with a spring-loaded double-lip seal (Rexroth R900908765) to reduce wear caused by frequent shaft rotation starts; ③ Control adjustment: Set the FR control’s pressure rise time to 0.5s (via the control valve’s throttle screw) to avoid pressure shocks during startup; ④ Motor protection: Use a soft starter to reduce inrush current during startup, which indirectly protects the pump’s coupling from impact; ⑤ Maintenance focus: Inspect the bearing clearance weekly (normal ≤0.03mm) and replace bearings every 6 months (instead of 12 months) to adapt to frequent load changes.
