1 квартал: What are the core performance parameters of the HHPC P70-B3H-ED3-F-R-2A high-pressure plunger pump?
А1: The key performance indicators of this plunger pump are as follows:
- Смещение: 70 см³/об (тот “P70” in the model name directly represents the displacement specification).
- Рейтинг давления: Maximum continuous working pressure reaches 350 бар (5075 пса); short-term peak pressure can withstand up to 400 бар (5800 пса), подходит для гидравлических систем высокого давления.
- Диапазон скоростей: Minimum stable operating speed is 600 rpm; maximum allowable input speed is 2800 rpm, compatible with most diesel or electric drive systems.
- Теоретический ход: At the maximum speed of 2800 rpm, the theoretical flow rate is approximately 196 L/мин (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 сСт, adapting to temperature changes in working environments (ranging from -20°C to 80°C).
2 квартал: What do the code segments in the HHPC P70-B3H-ED3-F-R-2A model name represent?
А2: Each code in the model has a clear technical meaning, helping to identify the pump configuration:
- “P70”: Basic model, indicating the displacement is 70 см³/об (plunger pump series).
- “Б3Х”: Structural and installation code, representing the pump’s flange type (SAE B standard) and shaft end configuration (3-keyway design for stable power transmission).
- “ЭД3”: Код режима управления, standing for electric proportional control with 3-stage pressure adjustment, supporting precise flow and pressure regulation via electrical signals.
- “ФР”: Directional control code, indicating the pump supports forward and reverse oil output, suitable for equipment requiring bidirectional hydraulic drive.
- “2А”: Seal and material code, meaning it adopts 2nd-generation high-temperature resistant oil seals (нитриловый каучук + PTFE composite) and grade A wear-resistant internal plungers.
Q3: What structural advantages make the HHPC P70-B3H-ED3-F-R-2A suitable for high-pressure working conditions?
А3: 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 (СКМ440), and the plungers are treated with chrome-plating + polishing (surface roughness Ra ≤ 0.2 мкм), 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 (до 92% в номинальных условиях).
- 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.
