description

The K3SP36 pilot pump adopts upgraded reinforced integral gear pump structure, professionally optimized for frequent start-stop, multi-action compound operation and complex load switching characteristics of small and medium excavators. Different from ordinary universal pilot pumps with poor precision, this model is strictly calibrated according to the original hydraulic parameters and installation dimensions of K3SP36 main pump supporting models, with ultra-stable pressure output and minimal flow pulsation. Equipped with high-hardness wear-resistant alloy gear set, reinforced anti-fatigue bearing assembly and high-temperature aging-resistant composite sealing system, it can maintain constant pilot pressure output for a long time after frequent hydraulic impact and continuous load operation. The high-rigidity one-piece pump body has excellent shock resistance, dust resistance and sediment erosion resistance, adapting to harsh working environments such as municipal renovation, earthwork backfilling and field mining.

advantages

  • Professionally customized and calibrated for K3SP36 main pump assembly, perfectly matching original installation size and pilot pressure parameters, supporting 1:1 non-destructive plug-and-play replacement without equipment modification, with high system matching degree and zero abnormal adaptation problems.
  • Adopting low-pulsation constant-pressure output technology, it effectively avoids pilot pressure fluctuation caused by frequent compound actions and load switching, thoroughly solving common faults such as slow response, weak operation and jitter of excavator working devices.
  • High-hardness alloy gear pair and reinforced bearing structure greatly improve wear resistance and structural stability, adapt to long-term high-frequency start-stop operation of small and medium excavators, and maintain long-term stable pilot pressure output.
  • High-quality anti-aging and high-temperature resistant sealing system resists long-term hydraulic cyclic impact and temperature changes, completely eliminates oil leakage and pressure attenuation, and effectively reduces equipment failure rate and maintenance costs.

FAQ

  • Q1: What are the common failure symptoms of K3SP36 pilot pump?
  • A: Typical faults include delayed operation response, weak boom/arm/bucket action, unstable idle pilot pressure, walking jitter and deviation, unsmooth swing compound actions, pump body oil leakage and abnormal operating noise.
  • Q2: Why does the machine have poor control sensitivity after long hours of work?
  • A: Long-term frequent operation causes wear of internal gears and bearings, increased internal leakage and decreased pilot pressure, resulting in insensitive hydraulic control and weak actions. Replacing the aging K3SP36 pilot pump can restore original control performance.
  • Q3: How to maintain K3SP36 pilot pump daily?
  • A: Keep hydraulic oil clean, replace hydraulic oil and filter elements regularly to prevent hard impurities from wearing precision gears. Regularly check the pump body for oil leakage and abnormal noise to ensure stable pilot pressure output.
  • Q4: How to extend the service life of K3SP36 pilot pump?
  • A: Avoid long-term overload operation and frequent sudden start-stop impact, maintain the cleanliness of the hydraulic system, reduce internal component wear and fatigue loss, and effectively extend the service life of the pilot pump.
