60-80dB(A)
100-120dB(A)
50-75 dB(A)
What is the main reason gear pumps are so loud?
The fluid gets compressed.
The motor runs loud.
Metal on metal contact is loud.
Fluid is flowing fast.
What are the advantages of the external gear pump?
Higher running speed
Handles higher viscosity
Higher operating temperature
They are louder
What is the shape of the divider in an internal gear pump?
Crescent
Circle
Half Circle
Rectangle
What is an advantage of a piston pump?
High Efficiency
Slow Cooling
Expensive
Not Complex
What is a disadvantage of a Piston Pump?
It is inefficient.
It cannot have a filter on the inside of the Pump.
There is no need for a Filter
It is noisy.
What is the difference between an Axial and Radial Piston Pump?
There is no difference
Radial Piston pumps uses pistons and axial piston pumps Do not
Axial piston pump parts lines up with the drive shaft
Radial Piston pump Parts line up with the drive shaft
What does the Swash plate and piston block connect to in an Axial Piston Pump?
The Drive Shaft
The Housing
The Swash plate
The Piston block
Name 3 components of an Axial Piston Pump
Contains only pistons
Pistons, Piston block, and Housing
Swash Plate, Belt, Piston.
Inlet, outlet, and closed ports
