النزوح: Usually in the range of 30 – 50 CM³/Rev. A larger displacement can provide sufficient flow to meet the high – power requirements of the D85 bulldozer's hydraulic system.
الضغط المقدر: 20 – 25 الآلام والكروب الذهنية (2900 – 3625 PSI). This is the continuous operating pressure that ensures the pump can stably supply hydraulic power under normal working conditions.
ضغط الذروة: Can reach 30 الآلام والكروب الذهنية (4350 PSI) to cope with short – term high – load working conditions, such as when the bulldozer encounters large – resistance objects during operation.
Rated Speed: 1800 – 2200 دورة في الدقيقة, which is adapted to the engine speed of the D85 bulldozer. على سبيل المثال, if the D85 is equipped with a Komatsu SAA6D140 engine, its rated speed is around 2000 دورة في الدقيقة, and the pump's rated speed needs to match the engine's output speed to ensure efficient power transmission.
السرعة القصوى: عمومًا, it does not exceed 2500 دورة في الدقيقة. Prolonged operation at high speeds should be avoided to prevent overheating and excessive wear of the pump.
Rotation Direction: Usually counter – clockwise (CCW) when viewed from the drive end, but it is recommended to verify with the specific model of the D85 bulldozer or refer to the equipment manual.
Ports: The inlet port is usually SAE 12 (1 – 1/8" NPT), and the outlet port is SAE 10 (3/4" NPT). The larger – diameter inlet port is conducive to improving the oil – suction capacity and ensuring a sufficient oil supply to the pump.
وزن: تقريبًا 25 – 35 كجم. The specific weight may vary slightly depending on the specific design and material of the pump.
