Cara kerja pompa piston variabel aliran aksial

Summary

This video explains the working of a variable displacement axial flow piston pump. It details the key components, such as the pump casing, piston, drive shaft, swashplate, inlet, and outlet, and how they work together to pump fluid. The pump operates by adjusting the angle of the swashplate, which controls the movement of the pistons. This variable displacement mechanism allows for the precise control of fluid flow, with the pistons either drawing in or expelling fluid based on the swashplate's angle. The pump is efficient in adjusting its output to meet varying fluid demands.

Takeaways

• 😀 The script explains the components of a piston pump, including the casing, piston, drive shaft, swashplate, inlet, and outlet.
• 😀 The swashplate is a crucial part that helps control fluid intake and output by adjusting the angle, which influences piston movement.
• 😀 The piston is responsible for sucking fluid into the cylinder and pushing it out, depending on the swashplate angle.
• 😀 The drive shaft transmits mechanical power from the engine to the pump, enabling the movement of components.
• 😀 The piston pump works through axial flow, where the fluid enters through the inlet, is compressed or moved by the piston, and exits through the outlet.
• 😀 The angle of the swashplate affects the piston’s movement: as the angle changes, the piston moves forward or backward, creating suction or pressure.
• 😀 A variable displacement pump allows the flow of fluid to vary based on the swashplate angle, which changes the pump’s capacity.
• 😀 When the swashplate is vertical (90°), no fluid flow occurs because there’s no angle to generate motion in the piston.
• 😀 The piston moves in a reciprocating motion when the swashplate angle changes, with the piston on one side moving backward (suction) and the other side moving forward (compression).
• 😀 The script concludes by noting that the system works continuously as the cylinder block rotates, ensuring fluid intake and output, which makes the pump operate as a variable displacement axial pump.

Q & A

What are the main components of a piston pump?

The main components of a piston pump are the pump casing, piston, drive shaft, swashplate, flash valve, cylinder block, inlet, and outlet.

What is the function of the swashplate in a piston pump?

The swashplate's function is to adjust the fluid intake and discharge during the suction stroke of the piston by changing the angle of the piston.

How does the piston work inside the cylinder block?

The piston is designed to rotate within the cylinder block as it turns, which creates suction and fluid movement based on the swashplate's angle.

What happens when pressure is applied to the valve in the piston pump?

When pressure is applied, the angle of the swashplate changes, causing the piston to move back and forth, which drives fluid into and out of the cylinder.

What does the movement of the piston depend on?

The movement of the piston depends on the angle of the swashplate, which alters the direction of the piston’s motion.

How does the piston pump create fluid flow?

Fluid flow is created by the piston moving back (sucking fluid in) and pushing forward (discharging fluid) based on the swashplate’s angle adjustment.

What happens when the swashplate is in a vertical position?

When the swashplate is in a vertical position (90°), no fluid flow occurs within the pump, as the piston remains stationary.

What is the significance of the variable displacement feature in a piston pump?

The variable displacement feature allows the pump’s flow rate to change based on the swashplate’s angle, providing adjustable fluid flow based on system requirements.

Why is this type of pump referred to as a variable displacement pump?

This pump is referred to as a variable displacement pump because its flow rate varies depending on the angle of the swashplate, which can be adjusted to change the piston’s motion.

How does the pump maintain continuous operation?

The pump maintains continuous operation by rotating the cylinder block, which causes the piston to constantly alternate between fluid intake and discharge.
