Piston Pump Manufacturers – Application Fields For Axial Piston Pumps
Despite some problems, this type of pump can contain most of the necessary loop control (swashplate angle control) to regulate flow and pressure, is very reliable and allows the rest of the hydraulic system to be very simple and inexpensive.
What is the role of axial piston pumps in these areas, the Piston Pump Manufacturers states:
The axial piston pump is used to power the jet’s hydraulic system, driven by the turbine engine’s main shaft gear. The system used on the F-14 uses a 9-piston pump that produces a standard system operating pressure of 3000 psi and a maximum flow rate of 84 per minute. gallon.
Automotive air conditioning compressors currently used for cabin cooling are primarily based on axial piston pump designs (other designs based on scroll compressors or rotary vane pumps) to accommodate their weight and space requirements and reduce vibration in the engine compartment of the vehicle. They have fixed displacement and dynamically adjustable variable displacement models, and depending on the design of the compressor, the actual swashplate can directly drive a set of pistons that mate with their edges through a set of hemispherical metal shoes or cap plates. One set of pistons is mounted by a rod.
They are also used in some high pressure cleaners. For example, Kärcher is available in several models powered by an axial piston pump with three pistons.
Axial reciprocating motors are also used to power many machines. They operate on the same principles as described above except that the circulating fluid is supplied under considerable pressure and the piston housing is rotated and shaft power is supplied to another machine. The general purpose of axial reciprocating motors is to power small earthworks, such as skid steers. Another use is to drive the torpedo’s screws.
