An axial piston pump uses a swashplate to move multiple pistons up and down, and can be used as a pump or part of other assemblies. The swashplate rotates to force the pistons to move in and out of the cylinder block. All parts must be precisely measured for proper function, and the pumps can be folded or straight depending on configuration. They can also be configured to operate on demand to save energy.
An axial piston pump is a piece of equipment that moves multiple pistons up and down. The pump typically does this with the shifting motion of a swashplate, a circular piece of metal with a hole in the middle that tilts down and then up to one side. It can be used simply as a pump or as part of other assemblies such as automotive engines or hydraulic motors.
A typical axial piston pump consists of a swashplate, piston, piston shoe, cylinder block or liner, and valve plate. The pistons are positioned vertically and equally spaced above the swash plate. Each piston comes with a piece of shoe. The pistons fit into holes in the cylinder block. Then the block is placed over the piston and swash plate so that it completely covers the assembly. A valve plate is then attached to the top of the cylinder block.
The swash plate is the key to the displacement motion of the axial piston pump. It is also commonly known as a cam plate, tilt plate or swash plate. When the pump is in motion, the swashplate rotates so that the thick and thin parts of the plate alternate between the pistons. This forces the pistons to move in and out of the cylinder block. The length of the piston movement depends on the depth of the swash plate.
All parts of an axial piston pump must be precisely measured for the part to function properly. Pistons in particular must be designed so that there is enough room for them to move in and out of the cylinder block, but not so much that they cannot stand upright. Each piece has an effect on the speed of the pump and the depth of movement of the piston.
Axial piston pumps that are part of other equipment are often built to fit the available space. This means they can be folded or straight, also known as inline, depending on the configuration you need. A bent pump will rely on a purpose built cylinder block rather than a swashplate for displacement motion. The pumps are powered by motor or electricity, depending on where and how the equipment will be used.
By responding to a specific signal, an axial piston pump can be configured to operate on demand. This can help save energy, as the pump is not running constantly. The feature is an alternative to the constant flow of energy expended by fixed displacement pumps.
