Competitive Advantage:
1. A7V250LV closed-circuit variable piston pump has a large displacement of 250cc. It can continuously output powerful power under high-pressure conditions and features excellent impact load resistance. It can stably handle continuous heavy-load operation scenarios of concrete pumps, mining equipment and other heavy machinery.
2. Developed specially for hydraulic closed circuits, it features fast variable adjustment response. The flow can change in real time with the load, bringing high power transmission efficiency and lower energy loss. The compact housing structure fits the compact overall layout of heavy construction machinery.
3. The core friction pairs adopt high-strength wear-resistant materials, adapting to harsh working conditions such as dust and high temperature on construction sites. Replacement parts are widely available in the market, easy for disassembly and maintenance, effectively reducing losses caused by downtime of heavy equipment.
The Analysis For Rexroth A7V250LV Piston Pump Common Breakdown:
1. Insufficient pump output flow and slow equipment movement. It is mostly caused by wear between cylinder block and pistons or scratched valve plate, which increases internal leakage. The pump fails to reach rated output flow, slowing down the actuators of the whole machine, reducing the efficiency of concrete transportation and mining operations. The problem becomes more obvious under heavy load.
2. Abnormal noise and violent vibration of pump body. The main causes are contaminated hydraulic oil, air entering the suction pipeline or damaged bearings. Impurities and cavitation continuously scour the precision internal parts of the pump. Vibration and noise keep worsening. Long-time operation may lead to fracture of internal parts and even sudden seizure of the pump core.
3. Failure of variable adjustment, unable to change output flow. Stuck spool of the variable mechanism and fatigue failure of control springs are common causes, making the pump unable to adjust displacement normally. The equipment power cannot be adjusted according to working conditions, resulting in excessive power waste or insufficient power for heavy loads.
