FAQ
Q: How do you size a hydraulic pump?
1. Determine system requirements: Determine the pressure (P) and flow (Q) required by the system, as well as the duty cycle and running time.
2. Consider efficiency: Estimate the efficiency (η) of the pump, which is usually between 70%-95%.
3. Select the pump type: Select the appropriate pump type according to the application, such as gear pumps, plunger pumps, etc.
4. Calculate the displacement of the pump: Use the formula Q = V * n * η, where V is the displacement of the pump and n is the speed of the pump.
5. Reserve margin: To cope with the peak demand of the system and possible future upgrades, appropriately increase the specification margin of the pump.
6. Check system compatibility: Make sure the pump specifications match other components of the system (such as motors, valves, pipes, etc.).
Q: How do you increase the flow of a hydraulic pump
1. Replace the pump with a larger flow rate.
2. Increase the speed of the pump, but within the safe range.
3. Increase the diameter of the suction pipe to reduce the suction resistance.
4. Expand the diameter of the discharge pipe to reduce pressure loss.
5. Optimize the system valve settings to ensure that the flow rate is not restricted.
6. Check and repair the system oil leak to reduce flow loss.
7. Use a more powerful motor to drive the pump.
8. Consider increasing the pump model appropriately.
When adjusting, make sure that all changes meet the system design requirements to avoid overload operation.
Q: How does the hydraulic pump work?
1. Suction process: When the rotor of the pump (such as gears, plungers, etc.) rotates, negative pressure will be generated at the suction port of the pump, so that the hydraulic oil in the oil tank is sucked into the pump.
2. Closing process: The rotor continues to rotate, and the sucked oil is sealed in the chamber of the pump to prevent backflow.
3. Extrusion process: As the rotor continues to rotate, the enclosed oil is pushed to the discharge port of the pump, and the oil is pressed into the hydraulic system under pressure.
4. Discharge process: Under pressure, the oil enters the system pipeline through the discharge port to complete a working cycle.
The hydraulic pump works continuously in this way, providing pressure and flow to the hydraulic system to drive actuators such as hydraulic cylinders and hydraulic motors.
