FAQ;

1. Special Scenario Troubleshooting

Q1: After a system overhaul, the pump’s LR2 control conflicts with the new directional valve—how to resolve the control logic mismatch?
A1: Control conflicts arise from mismatched pressure/flow signals between the LR2 pump and new valve—resolution steps: ① Identify Conflict Type: 1) “Pressure Conflict”: Valve requires 300 bar, but pump limits to 250 bar (LR2 power setting too low); 2) “Flow Conflict”: Valve demands 80 L/min, but pump only supplies 50 L/min (swashplate angle restricted); ② Parameter Calibration: 1) For Pressure Conflict: Increase the LR2 power limit by adjusting the power feedback sensor (e.g., from 37 kW to 41 kW) to allow higher pressure; 2) For Flow Conflict: Adjust the LR2 control valve’s maximum displacement screw (clockwise 1/2 turn) to increase flow output; ③ Signal Synchronization: Connect the directional valve’s load signal (LS port) to the pump’s control port Y—this creates a closed loop where the pump adjusts flow/pressure based on the valve’s demand; ④ Testing & Tuning: Operate the valve through all positions while monitoring pump pressure/flow—use a oscilloscope to verify that pump signals (4-20mA) align with valve signals; adjust the LR2 valve’s damping to eliminate signal lag (≤0.1s); ⑤ Documentation: Record the calibrated parameters (power limit, flow range) and store them in the system manual—critical for future maintenance. This process resolves 95% of control conflicts between LR2 pumps and new hydraulic components.
Q2: The pump’s case drain oil turns black after 300 hours of operation in a coal mine—what is the cause and how to mitigate it?
A2: Black case drain oil indicates severe contamination by coal dust and wear particles—mitigation measures: ① Root Cause Analysis: 1) Coal dust enters the system via damaged suction strainers or breather filters; 2) Abrasive dust causes accelerated wear of piston shoes and swashplate, generating black metal particles; ② Immediate Actions: 1) Drain all contaminated oil and flush the system with 50L of clean oil (circulate for 10 minutes); 2) Replace all filters (suction, return, inline) with high-efficiency versions (25μm); 3) Disassemble the pump to clean piston shoes and swashplate (replace if wear exceeds 0.03mm); ③ Long-Term Mitigation: 1) Install a pressurized tank breather (Rexroth R901423567) that maintains positive pressure in the tank (prevents dust ingestion); 2) Use a magnetic filter in the case drain line to capture metal particles; 3) Shorten oil change intervals to 1 month and filter cleaning to 3 days; 4) Apply a coal dust repellent coating (Rexroth CD 500) to the pump housing to prevent dust accumulation; ④ Monitoring: Use a particle counter (Rexroth PC 200) weekly to measure oil contamination—NAS 9 class is the maximum allowable in coal mines. Failure to mitigate will reduce pump life to 1000-1500 hours (vs. 8000+ hours in clean environments).
