FAQ:
1. Q: What types of hydraulic oil are compatible with PV7 series pumps?
A: It is compatible with mineral-based hydraulic oils, synthetic hydraulic oils, and biodegradable hydraulic oils that meet the requirements of ISO 6743-4 (category HM, HV, HG). The recommended viscosity range is 10–40 mm²/s at operating temperature.
2. Q: How to select the appropriate displacement model of PV7 series pumps?
A: Select according to the system’s required flow rate and working pressure. The displacement range of PV7 series is 4–180 cm³/rev; calculate the flow rate via the formula: Flow (L/min) = Displacement (cm³/rev) × Speed (rpm) ÷ 1000, and match it with the system’s actual flow demand.
3. Q: Can the PV7 series pumps be operated in both clockwise and counterclockwise directions?
A: Most standard PV7 models are designed for fixed rotational direction, but customized models with reversible rotation are available upon request; confirm the rotation direction requirements with the supplier before purchase.
4. Q: What is the recommended oil temperature range for PV7 series pumps during operation?
A: The optimal operating oil temperature is 40–60 °C; the allowable short-term maximum temperature should not exceed 80 °C, and the minimum temperature should not be lower than 10 °C to avoid viscosity abnormalities affecting performance.
5. Q: What causes abnormal noise during the operation of PV7 series pumps?
A: Common causes include insufficient oil suction (such as clogged suction filters, too-small suction pipe diameters), air mixed in the hydraulic oil, excessive oil viscosity, worn pump internal components, or loose mounting bolts.
