8. Installation & Operation Notes

Standardized installation and operation specifications effectively avoid abnormal noise, pressure fluctuation, oil leakage and premature wear, greatly extending the service life of high-pressure mining piston pumps under extreme working conditions:

• Shaft Coaxiality Requirement: Keep the coaxiality error between the pump shaft and motor shaft within 0.1mm. Only use elastic coupling for connection. Rigid installation, offset and tilted assembly are forbidden to prevent shaft deformation, vibration and abnormal wear.

• Oil Suction Pipeline Standard: Ensure the suction pipeline is fully sealed, airtight and unobstructed. Air inhalation will cause pressure fluctuation, loud noise and excessive temperature rise. Regularly check pipeline aging and loose joints for stable system operation.

• Hydraulic Oil Cleanliness: Adopt qualified anti-wear hydraulic oil and keep the oil clean without metal debris, dust and turbidity. Impurities will scratch the internal pump core and cause internal leakage and pressure loss. Replace hydraulic oil and filter elements regularly.

• Pressure & Speed Limitation: Strictly prohibit long-term over-rated pressure, over-peak pressure and over-speed operation. Long-term overload operation will accelerate seal aging and pump core fatigue, leading to performance attenuation and shortened service life.

• Startup & Commissioning Rules: Bleed air completely before initial startup or hydraulic oil replacement. Operate the pump under no-load condition for 3–5 minutes, check for abnormal noise and stable pressure, then apply load gradually. Never start with full load to prevent instantaneous impact damage to internal components.

• Working Environment Adaptation: Ensure good ventilation and heat dissipation for the pump unit. Keep hydraulic oil temperature between 30℃–55℃. Avoid long-term exposure to high temperature, heavy dust and humid conditions to prevent seal aging and oil deterioration.
