Mobile charging units for hydropneumatic accumulators
The mobile unit is designed for pressurized nitrogen (up to 30 MPa) charging of hydropneumatic accumulators and vessels. Nitrogen can be charged from a vessel or a pipeline with nitrogen pressure of no more than 2.0 MPa.
The unit comprises hydraulic
system, pneumatic equipment block and electric control cabinet. It is assembled on a cart which can be moved around without any lifting
devices.
The hydraulic system comprises
a reservoir with a built-in heater, oil indicator, temperature and level
switches, a radial-piton pump, a hydropneumatic accumulator (hydropneumatic
transducer) and an electrically controlled hydraulic directional valve.
