Abstract
A multi-stage compressor (1) for compressing gases with a low-pressure region (2) and a high-pressure region (5), wherein at least one rotary compressor (3) is provided in the low-pressure region (2), and at least one reciprocating piston compressor (6) with two cylinders (7) is provided in the high-pressure region (5), and wherein a common engine (4) is provided for driving the rotary compressor (3) and the reciprocating piston compressor (6), wherein the cylinders (7) are arranged to be rotated relative to each other by 180° in the high-pressure region (5).
Claims6
A multi-stage compressor for compressing gases with a low-pressure region and a high-pressure region, at least one screw-type compressor in the low-pressure region, at least one reciprocating piston compressor with two cylinders in the high-pressure region, a common engine for driving both the screw-type compressor and the reciprocating piston compressor, said engine having a crankshaft with a longitudinal axis that is substantially horizontal, said engine being disposed laterally next to the reciprocating piston compressor, wherein stepped pistons or double-acting pistons are received in the cylinders, and the cylinders oppose each other by 180° in the high-pressure region with respective longitudinal axes of said cylinders extending substantially horizontally such that the reciprocating piston compressor is arranged in a boxer construction that can neutralize forces of inertia from the reciprocating pistons during each crankshaft rotation, wherein the screw-type compressor is coupled directly to the engine-driven reciprocating piston compressor.
A multi-stage compressor for compressing gases with a low-pressure region and a high-pressure region, at least one screw-type compressor in the low-pressure region, at least one reciprocating piston compressor with two cylinders in the high-pressure region, a common engine for driving both the screw-type compressor and the reciprocating piston compressor, said engine having a crankshaft with a longitudinal axis that is substantially horizontal, said engine being disposed laterally next to the reciprocating piston compressor, wherein stepped pistons or double-acting pistons are received in the cylinders, and the cylinders oppose each other by 180° in the high-pressure region with respective longitudinal axes of said cylinders extending substantially horizontally such that the reciprocating piston compressor is arranged in a boxer construction that can neutralize forces of inertia from the reciprocating pistons during each crankshaft rotation, wherein the screw-type compressor is coupled directly to the engine-driven reciprocating piston compressor, whereby the multi-stage compressor is installable in an ISO container having a width of eight feet.
A compressor plant mounted on a ship, with a multi-stage compressor for compressing gases with a low-pressure region and a high-pressure region, at least one screw-type compressor in the low-pressure region, at least one reciprocating piston compressor with two cylinders in the high-pressure region, a common engine for driving both the screw-type compressor and the reciprocating piston compressor, said engine having a crankshaft with a longitudinal axis that is substantially horizontal, said engine being disposed laterally next to the reciprocating piston compressor, wherein stepped pistons or double-acting pistons are received in the cylinders, and the cylinders oppose each other by 180° in the high-pressure region with respective longitudinal axes of said cylinders extending substantially horizontally such that the reciprocating piston compressor is arranged in a boxer construction that can neutralize forces of inertia from the reciprocating pistons during each crankshaft rotation, wherein the screw-type compressor is coupled directly to the engine-driven reciprocating piston compressor.
