Typical: ~18 mL/rev (may vary by specific bulldozer model)
Note: Displacement defines the volume of oil pumped per revolution.
Pressure Rating
الضغط المقدر: 16–20 MPa (2321–2900 psi)
Maximum Pressure: 25 الآلام والكروب الذهنية (3626 PSI, short-term operation)
Function: Determines the pump’s ability to generate hydraulic force.
نطاق السرعة
Rated Speed: 1500–2000 rpm (normal operating speed)
السرعة القصوى: 2300 دورة في الدقيقة (transient limit)
Impact: Higher speed increases flow rate but may affect efficiency.
معدل التدفق
في 1800 دورة في الدقيقة: ~32 L/min (calculated as displacement × speed; actual may vary with pressure and oil viscosity).
Efficiency
Volumetric Efficiency: ≥90% (efficiency in oil volume transfer)
Mechanical Efficiency: ≥85% (energy conversion efficiency)
