DX700 Fan Pump for Doosan DX700 Excavator spare parts

Short Description:

The DX700 fan pump is a heavy-duty original hydraulic cooling pump exclusively configured for the Doosan DX700 70-ton large mining excavator. As the core power source of the independent hydraulic heat dissipation system, it provides stable and continuous pressure and flow power for the matched fan motor, forming a complete closed-loop intelligent constant-temperature cooling circuit.

description

The DX700 heavy-duty fan pump adopts upgraded mining-grade reinforced hydraulic pump structure, specially optimized for the high-heat generation and super-heavy load cycle working characteristics of Doosan DX700 large excavators. Different from ordinary general-purpose replacement pumps, it strictly follows the original hydraulic calibration parameters and installation dimensions of DX700 equipment, with ultra-low internal leakage and linear and stable flow pressure output. Built with reinforced wear-resistant internal flow distribution components, anti-fatigue rotating mechanism and high-temperature aging-resistant sealing system, it can maintain stable working performance without attenuation after long-term high-pressure and high-temperature cyclic hydraulic impact. The high-rigidity integrally cast pump body has excellent vibration resistance, dust and sediment erosion resistance and hydraulic impact resistance, perfectly adapting to harsh mine construction environments.

advantages

Adopting mining-grade low-leakage hydraulic technology, it effectively avoids flow attenuation and insufficient hydraulic power under long-term super-heavy load and high-temperature working conditions, thoroughly solving the high-temperature alarm pain point of DX700 large excavator in extreme mining scenarios.
Precision internal matching process ensures linear and stable pressure output, synchronous and stable speed regulation of the supporting fan motor, no fan jitter or speed drop during peak load operation, and continuous and powerful heat dissipation efficiency.
Original high-temperature anti-aging composite sealing system resists long-term high-pressure and high-temperature cyclic hydraulic impact, completely avoiding oil leakage and performance degradation, reducing equipment failure rate and downtime loss.
Reinforced high-rigidity cast pump body features excellent anti-vibration, anti-impact and anti-dust erosion capabilities, adapting to harsh high-dust and high-vibration mine environments, with service life far exceeding ordinary replacement pumps.
Intelligent load adaptive oil supply design automatically adjusts flow and pressure according to equipment load and ambient temperature, realizing on-demand heat dissipation, reducing invalid energy consumption, and improving equipment fuel economy and construction efficiency.

FAQ

Q1: What are the common failure symptoms of DX700 fan pump?
A: Typical faults include insufficient fan driving power, slow temperature drop, unstable fan speed, pump body vibration and abnormal noise, shaft end oil leakage, and frequent engine hydraulic system high-temperature alarms under heavy load.
Q2: Why does the equipment overheat under continuous mining load?
A: Long-term full-load operation causes internal wear of the fan pump, increased internal leakage, and decreased output flow pressure, resulting in insufficient fan speed and weakened heat dissipation capacity. Timely replacement of the aging fan pump can restore original heat dissipation performance.
Q3: How to maintain DX700 fan pump daily?
A: Regularly clean dust on the radiator and fan blade to avoid system overload. Check the pump body for oil leakage and abnormal noise. Replace hydraulic oil and filter elements on schedule to prevent hard impurities from wearing internal precision components.
Q4: How to extend the service life of DX700 fan pump?
A: Avoid long-term extreme high-temperature overload operation and sudden hydraulic pressure impact. Keep the hydraulic system oil clean, reduce fatigue wear of internal parts, and effectively extend the service life of the fan pump.
Q5: Is debugging required after replacing DX700 fan pump?
A: The DX700 fan pump adopts original standard installation parameters and size. It supports plug-and-play replacement. No complex professional debugging is needed after installation, and the equipment can resume normal heat dissipation operation.
