  7. Other High-End Industrial Applications: High-precision injection molding machines, industrial robots, etc., requiring stable and precise hydraulic power

V. Installation and Maintenance Points

  1. Installation Notes:
    1. Ensure the coaxiality error between the pump shaft and the drive shaft is ≤0.08 mm to avoid vibration and wear caused by misalignment
    2. The suction pipeline should be short and straight, with a diameter 1.2-1.5 times that of the pump suction port, and avoid air leakage
    3. It is recommended to install a high-precision suction filter (filtration accuracy ≤50μm) and a pressure relief valve to protect the pump body
    4. Before initial start-up, fill the pump with clean hydraulic oil and exhaust thoroughly to avoid dry friction
  2. Maintenance Recommendations:
    1. Use hydraulic oil above NAS 6 grade, and regularly check the oil cleanliness, oil level and oil temperature
    2. Replace the filter element every 2000 working hours and the hydraulic oil every 6000 working hours (adjust according to the working environment)
    3. Regularly check the vane wear and pump core tightness, and replace vulnerable parts in time to ensure precision
    4. Avoid long-term operation at ultra-high pressure and ultra-high temperature, and shut down for inspection immediately if abnormal noise, vibration or oil leakage occurs

VI. Selection Reference

  1. Select the appropriate pump core size and pressure grade according to the system’smaximum working pressure and precision requirements
  2. Choose fixed or variable displacement configuration according to system flow regulation needs (electric control is recommended for high-precision regulation)
  3. Combine installation space and system compatibility to select single/double/triple pump configuration, and pay attention to matching with T6/T67 series if upgrading
  4. Pay attention to the driving speed and oil quality requirements to ensure the pump works in the optimal working condition
  5. For special working conditions (high temperature, high corrosion), select the corresponding special material and seal configuration
As an upgraded and enhanced product of the T6/T67 series, the Parker T7 series ultra-high pressure precision vane pump integrates ultra-high pressure bearing, high precision control and long-term reliability, providing a high-end and stable hydraulic power solution for high-end industrial equipment.
