Competitive Advantage:
This Rexroth A10VSO 45 DFR/31 L-PKC62 K68 variable piston pump adopts DFR pressure and flow compound control. It can output oil on demand and adjust displacement automatically according to loads with fast response, cutting energy consumption. It is ideal for construction machinery with intermittent operation to reduce operating costs.
Designed with mature 31-series structure, this pump has precisely matched friction pairs, strong impact and wear resistance, and stable pressure resistance. It works reliably under harsh conditions like dust and large temperature difference, extending service life and lowering downtime.
It comes with standard mounting interface for great compatibility. It can be easily fitted to injection molding machines, loaders and road machinery. With mature spare parts supply chain, it is convenient for replacement and maintenance, an ideal power source for equipment repair and retrofit.
The Analysis For Rexroth A10VSO Piston Pump Common Breakdown:
The pump delivers insufficient flow and actuators move slowly. It is usually caused by worn pistons and valve plate, stuck variable mechanism or blocked suction filter. This failure will directly reduce the overall working efficiency and fail to reach rated speed.
Abnormal noise and heavy vibration occur during operation. Common causes include contaminated hydraulic oil, air entering the oil circuit or damaged bearings. Continuous noise and vibration will speed up damage of internal precision parts and even lock up the pump.
System pressure fails to build up and the equipment lacks power under load. It mainly results from internal leakage due to aging seals or worn/stuck DFR control spool. Unstable pressure will weaken the load capacity and the machine cannot finish rated work.
