2. Application Scenarios and Advantages
PV2R1-23-F-RAA-40
Typical applications:
Injection molding machine auxiliary circuit: driving mold opening and closing, ejector movement, and low flow demand conditions.
Light machine tools: providing stable power for tool feeding and worktable movement.
Advantages:
Compact structure: suitable for equipment with limited installation space.
Low noise: optimized blade design to reduce operating noise.
3. Selection and maintenance guide
（1）Selection points
Displacement matching: Select the displacement according to the maximum flow demand of the system to avoid too large or too small displacement.
Pressure requirement: Confirm the maximum pressure of the system and select a pump with sufficient pressure resistance.
Installation method: Select flange installation (F) or foot installation according to the equipment space.
Interface direction: The RAA mark corresponds to the oil port position, which needs to be confirmed in conjunction with the hydraulic diagram.
（2） Maintenance recommendations
Oil cleaning: Regularly replace hydraulic oil and clean the oil filter to prevent contamination.
Temperature control: Avoid excessive oil temperature and install a cooler if necessary.
Pressure monitoring: Install a pressure gauge to monitor system pressure in real time.
Seal inspection: Regularly check the shaft seal and O-ring and replace them immediately if leakage is found.
4. Common Problems and Solutions
（1）Insufficient pressure
Reason: internal wear of hydraulic pump, overflow valve failure, low oil viscosity.
Solution: Check and repair worn parts, adjust or replace overflow valve, and replace oil with appropriate viscosity.
（2）Excessive noise
Reason: loose installation, non-concentric coupling, oil suction pipe blockage, air in the oil.
Solution: Reinstall and fix, adjust the coupling, clean the oil suction pipe, and remove the air.
（3）Unstable flow
Reason: Blade wear, stator curve wear, oil contamination.
Solution: Replace worn blades or stators, clean or replace oil.
4. Summary and Recommendation
PV2R1-23-F-RAA-40 is a cost-effective vane pump launched by He Hydraulics for small and medium-sized hydraulic systems. It takes into account both performance and reliability and is suitable for users who are sensitive to space, noise and cost.
