Notes for Rexroth A20VL Series Axial Piston Variable Pump
- Compatibility of Hydraulic Fluids: Make it a point that all parts work well with your choice of hydraulic fluid. Find out if the seal and hose materials or casings and paint finishes are compatible with the hydraulic fluid.
- Reservoir: Use a larger reservoir than that employed in mineral oil operation because HF fluids have poor air and dirt elimination capabilities which require longer standing time. Installation of baffles in the reservoir can aid separation efficiency enhancement for the fluid​.
- Filters: The life span of the system should be extended by employing reliable filtration. Ensure that effective filtration measures are put in place and that the efficiency of filtration is monitored regularly. Hydraulic fluid cleanliness level must not exceed relevant cleanliness grade due to solid particle contamination​.
- Pumps and Motors: Speed, operating pressure, and suction characteristics should be strictly according to manufacturer specifications when using HFD fluids; Standard pressure ratings do not change while permissible drive speeds must be reduced because medium density is higher than usual​.
- System Design and Operation: When designing, operating, and maintaining hydraulic systems take into account special properties exhibited by HF hydraulic fluids during this time; Keep density/compressibility relationship between these two variables under consideration as it affects response characteristics exhibited by control valves; consult manufacturer where necessary regarding suitability​.
- Changing Hydraulic Fluids: Ensure cleanliness is maintained in a system while changing over from one type or brand name of hydraulic fluid to another through proper flushing procedures; It takes different times for different types of hydraulic fluids to complete the process hence warm up the system during changeover so as to save on time​​.
- Start-Up and Operation: After filling correctly with operating fluid start under partial load then increase gradually to full load once stable; Some components may need system bleeding especially within the first few days after installation therefore ensure filters are clean at all times​.
- Temperature Management: For HFA, HFB, HFC due to limited low temperature & bad heating properties there should exist enough cooling surfaces on a reservoir or a separate cooling system may be necessary; On the other hand heating may be required for HFD fluids at low temperature​.
- Evaporation Losses: For HFA, HFB, and HFC fluids use a breather type of lid on the reservoir to significantly reduce evaporation losses​.
