Competitive Advantage:
This Rexroth A7VO107LR/63L-NPB01 variable piston pump adopts LR constant power control. It automatically adjusts displacement with load to prevent engine overload. It achieves remarkable energy saving under fluctuating load conditions such as concrete mixers and shredders and reduces fuel consumption.
It features compact size and high power density with excellent shock resistance. Its internal friction pairs are precisely machined. It can run steadily for a long time in harsh dusty and heavy-duty environments, cutting unexpected breakdowns and extending service life.
With industry-standard mounting dimensions and readily available spare parts, it is compatible with concrete mixers, waste recycling shredders and other engineering machinery. Easy for replacement and maintenance, it is a preferred hydraulic power component for equipment repair and retrofit.
The Analysis For Rexroth A7VO Axial Piston Pump Common Breakdown:
Insufficient pump flow leads to slow equipment movement. It is generally caused by worn valve plate and piston slippers, or blocked suction line with excessive suction resistance. This will directly result in weak output of actuators and lower overall working efficiency.
Abnormal noise and vibration occur while the pump is running. It is often triggered by contaminated hydraulic oil, air ingression or worn bearings. Continuous vibration and noise will scratch internal precision parts rapidly, and may lock up the pump in severe cases.
Unstable system pressure and weak load capacity. It mainly comes from stuck or worn spool of LR control valve, or internal leakage caused by aging seals. The pump cannot build stable pressure and fail to meet heavy-duty operation requirements.
