高圧台湾中国 HHPC プランジャーポンプオイルポンプ HHPC P70-B3H-ED3-F-R-2A

A1: The key performance indicators of this plunger pump are as follows:

変位: 70 cm3/r (の “P70” in the model name directly represents the displacement specification).
圧力定格: Maximum continuous working pressure reaches 350 バー (5075 psi); short-term peak pressure can withstand up to 400 バー (5800 psi), 高圧油圧システムに適しています.
速度範囲: Minimum stable operating speed is 600 RPM; maximum allowable input speed is 2800 RPM, compatible with most diesel or electric drive systems.
理論的な流れ: At the maximum speed of 2800 RPM, 理論上の流量はおよそ 196 l/min (calculated by displacement × speed), meeting the oil supply demand of multi-execution component systems.
Oil Viscosity Adaptability: Works normally with hydraulic oil of 10-1000 cSt, adapting to temperature changes in working environments (ranging from -20°C to 80°C).

A2: Each code in the model has a clear technical meaning, helping to identify the pump configuration:

“P70”: Basic model, indicating the displacement is 70 cm3/r (plunger pump series).
“B3H”: Structural and installation code, representing the pump’s flange type (SAE B standard) and shaft end configuration (3-keyway design for stable power transmission).
“ED3”: 制御モードコード, standing for electric proportional control with 3-stage pressure adjustment, supporting precise flow and pressure regulation via electrical signals.
“F-R”: Directional control code, indicating the pump supports forward and reverse oil output, suitable for equipment requiring bidirectional hydraulic drive.
“2a”: Seal and material code, meaning it adopts 2nd-generation high-temperature resistant oil seals (ニトリルゴム + PTFE composite) and grade A wear-resistant internal plungers.

A3: This plunger pump has 3 key structural designs to ensure reliability under high pressure:

Core Component Material: The cylinder block is made of high-strength forged steel (SCM440), and the plungers are treated with chrome-plating + polishing (surface roughness Ra ≤ 0.2 μm), enhancing wear resistance and pressure resistance.
Pressure-Balanced Design: Equipped with a built-in pressure-compensated valve and a multi-layer oil distribution plate, which balances the internal pressure of the pump, reduces leakage, and improves volumetric efficiency (まで 92% 定格条件下で).
Heat Dissipation Structure: The pump body adopts a finned heat dissipation design, increasing the heat dissipation area by 30% compared to ordinary plunger pumps, effectively controlling the oil temperature rise during long-term high-pressure operation.
