Some aircraft can deploy a ram air turbine (RAT) to generate hydraulic power. The hydraulic hand pump is used in some older aircraft for the operation of hydraulic subsystems and in a few newer aircraft systems as a backup unit. Hand pumps are generally installed for testing purposes, as well as for use in emergencies.

Hydraulic Pumps. Several types of hydraulic pumps driven by a variety of power sources can be found in aviation applications. Pumps include: Gear Pumps. Gear pumps use meshing gears to pump fluid. Gear pumps are fixed displacement-type pumps, as they move a specific amount of fluid per rotation.

2021年2月9日 · Basic aircraft hydraulic systems contain 4 main components: the hydraulic reservoir which is a store of fluid, the pump which supplies the pressure, and the selector valve which controls the actuator.

2022年9月28日 · Pumps. A hydraulic system requires a pump to power the system and ensure that fluid under pressure is delivered to the actuators when required. In the simplest hydraulic systems, the pump is provided by a piston and cylinder arrangement that increases the fluid pressure when pressed. This is how many light aircraft braking systems operate.

2024年8月20日 · The primary components of an aircraft hydraulic system include a reservoir, pump, actuators, valves, tubes, hoses, and filters, just as with traditional hydraulic systems. However, how they look, what they’re made from and where they’re located are vastly different than you’d expect.

EDPs serve as the primary supply of hydraulic flow and pressure for the hydraulic users within the aircraft system. The typical EDP configuration is a pressure-compensated, variable-displacement axial piston pump capable of varying the volume of fluid delivered to …

Hydraulic Pumps: These pumps are responsible for generating the hydraulic pressure needed to move components. They are often driven by the aircraft’s engines, but electric pumps or auxiliary power units (APUs) may also be used.

2019年3月10日 · 2.3 Hydraulic Pumps. Both A and B hydraulic systems have an engine-driven pump (EDP) and an ACMP. The system A engine-driven pump is installed on the number 1 engine and the system B engine-driven pump is installed on the number 2 engine. The AC pumps are controlled by a switch on the flight deck.

AeroControlex designs and manufactures fixed clearance gear, positive displacement gear, gerotor, and centrifugal pumps for applications in lubrication, scavenge, fuel, coolant, potable water and hydraulic systems. Our capabilities include electric motor driven and …
