AIRCRAFT HYDRAULIC SYSTEMS
- Drive generators
- Hydraulic pumps
- Hydraulic plants
- Hydraulic motors
- Hydraulic distributors with electromagnet control
- Hydraulic systems units
PUMP PLANTS
AC "Rubin" has been designed several structures of pump plants with the theoretic displacement 2 sm3/r at the delivering pressure from 100 to 220 kgf/sm2.
Pump plants have a high specific coefficients and are corresponding the present-day International standards.
PURPOSE
Pump plants are designed to provide aircraft hydraulic system with power and are used as the principle or alternate power sources.
SRUCTURE
Pump plants are the regulated axial-plunger pumps driven by the DC or AC 3-phases electro-engines.
Pump plants are designed applying four stages scheme: suction, pressure, return, drain.
