advantage

- Adjustable speed following hydraulic flow for intelligent temperature control
Speed varies synchronously with hydraulic flow, automatically adjusting fan speed according to coolant temperature, avoiding engine overheating and unnecessary power waste.
- Low noise gear profile design reduces vibration under continuous high-speed rotation
Optimized gear tooth profile lowers meshing noise and vibration during long-time continuous rotation, extending service life of fan assembly and radiator.
- Heat-resistant cast housing adapts to high-temperature engine compartment environment
Stress-relieved cast shell maintains structural stability under long-term high ambient temperature, resisting thermal deformation and fatigue damage.
- Anti-wear gear pair maintains stable torque under fluctuating working pressure
Hardened gear pair keeps consistent output torque when pressure fluctuates during cyclic excavation, ensuring stable cooling capacity under variable load.
- Integrated valve structure simplifies piping layout and reduces leakage risk
Built-in valve structure reduces external pipeline connections, lowering risk of pipe vibration and oil leakage in compact engine bay.
- Thermal cycle bench test simulating long-time heavy mining excavation work
Each motor undergoes repeated thermal cycling bench test to verify stable performance under continuous high-temperature mining excavation cycles.

FAQ

Q1: Which machine does PHM20.19L5-48S9-LMB/MB-V-EL-D-GB-D fan motor fit?
A1: This hydraulic fan motor fits Lovol 480 excavator. Confirm machine serial number before purchase.

Q2: What hydraulic function does this fan motor support?
A2: It provides rotary power for cooling fan system, automatically controlling engine water temperature and hydraulic oil temperature for heavy-duty excavation, mining and earthmoving projects.

Q3: What are typical failure symptoms of worn fan motor?
A3: Typical symptoms: insufficient fan rotating torque, fan speed cannot rise under high temperature, obvious noise during rotation, high oil temperature after long operation, pressure fluctuation, shaft seal oil leakage.

Q4: What inspections should be done before installing new fan motor?
A4: Inspect fan pump, cooling circuit control valve and hydraulic hoses and filter elements. Fully flush hydraulic tank and pipelines to remove metal debris. Replace degraded hydraulic oil before assembly.

Q5: What hydraulic oil should be used for this fan motor?
A5: Use ISO VG46 anti-wear hydraulic oil. Working temperature -20℃~108℃. Do not mix different oil brands, avoid long continuous running under peak pressure.
