PURPOSE

Electrohydraulic steering gears of РГПМ type are designed for installation on small crafts of various classes and purposes.

Electrohydraulic steering gears of РГМ type are designed for installation on small crafts of various classes and purposes, on the ones with a specified operating area service.

DESIGN

The power drive of gears of РГПМ type is a common part of two autonomous steering gears:

  • main steering gear with motor-driven pump unit and joystick-manipulator, start-protecting and signaling electric equipment connected to ship mains, 3-phase a.c., 50 Hz, 380 V and d.c., 24 V;
  • auxiliary steering gear with pump unit, where operator’s force at the handwheel is transformed in hydraulic energy.

“Non-following” control mode – from a wheel house or from joystick-manipulator or from handwheel without changing-over in hydraulic system. Rudder angles control is provided by indicator system “transmitter-receiver” connected to ship’s mains, 1-phase a.c., 50 Hz, 127 V.

Main steering gear of РГМ type – manual, hydraulic, with working fluid supply from hand-operated pump to hydraulic cylinder.
