Electric Motor Driven Pump

Some aircraft can deploy a ram air turbine rat to generate hydraulic power.

Electric motor driven pump.

The ac electric motor used in a vfd system is usually a three phase induction motor some types of single phase motors or synchronous motors can be advantageous in some situations but. A variable frequency drive is a device used in a drive system consisting of the following three main sub systems. The difference from an air operated diaphragm pump is the centre section of this pump as it uses an electric drive instead of compressed air. Both dc and ac motors with full control are available and can be adapted to the application s individual need.

The diaphragm metering pump offers a number of power end versions also suitable for use in areas at risk from explosion. Robust motor driven metering pumps like the sigma 2 basic guarantee excellent process reliability with their patented multi layer safety diaphragm. Figures in the body of this table show the horsepower needed to drive a positive displacement hydraulic pump and would be valid either for electric motor or engine drive. Ac motor main drive controller assembly and drive operator interface.

Assuming a pump efficiency of 85 which would be representative of most positive displacement pumps. Power driven pumps are the primary source of energy and may be either engine driven electric motor driven or air driven. The table was calculated from the formula.

Eaton s electric motorpumps are specifically designed and manufactured to meet a variety of critical performance applications providing a wide range of hydraulic pressure options provided in an ac fixed or variable frequency configuration or dc brush and brushless design. Electric motor driven pumps 3. Electric motor driven pumps can be used as primary supplemental or emergency backup hydraulic power in a variety of aerospace applications. Install both a union and a gate valve not furnished on the discharge side of the pump for service convenience.

The centre section of this pump is filled with pressurised air and is mechanically moved left right by the motor so it pushes and pulls the diaphragm from left to right.
