FAQ;
What are the rated pressure and peak pressure of the A10VSO45 pump?
The rated pressure of the A10VSO45 pump is 280 bar, and the peak pressure (for short-term, intermittent operation) can reach up to 350 bar. Note that peak pressure should not be used continuously to avoid premature wear or damage to internal components.
2. Performance & Troubleshooting
Q1: What causes insufficient output flow or no oil discharge from the pump?
Common causes include three main categories:
Inadequate suction: This may result from excessive resistance in the suction line (e.g., undersized or overly long hoses), insufficient oil replenishment (e.g., pump speed exceeding the rated limit, low oil level in the tank), air leakage in the suction line (loose connections or damaged seals), or a clogged suction filter.
Excessive internal leakage: Possible issues include scratches on the valve plate, poor sealing of the check valve in the variable displacement mechanism, or sand holes/abrasion marks on the mating surfaces of the pump body and valve plate.
Mechanical misalignment: The swashplate may be set to a minimum tilt angle (resulting in minimal displacement), or the motor may be running in the reverse direction (preventing normal piston movement).
Q2: Why does the pump produce vibration and abnormal noise during operation?
Vibration and noise typically stem from two sources:
Mechanical issues: Misalignment between the pump shaft and motor shaft (critical for high-speed or high-power applications), damaged bearings in the rotating shaft or faulty couplings, or loose mounting bolts.
Wear-related noise: Excessive wear of the bushings at the variable displacement head. This often occurs if the pump is started without sufficient oil in the power unit (causing dry friction at the bushing interface) or if the lubricating oil is contaminated with impurities.
Q3: What leads to overheating of the A10VSO45 pump?
Overheating is usually caused by:
Mechanical friction: Increased friction between moving parts such as bearings, pistons, and the cylinder block (often due to wear, lack of lubrication, or misalignment).
Fluid friction: Excessive resistance in the oil flow path (e.g., narrow hoses, blocked valves) or turbulent flow inside the pump.
Excessive system pressure: A clogged oil filter can cause a pressure buildup in the system, forcing the pump to work under overload and generating excess heat.
