摘要： The reciprocating compressor comprises a compressor frame, a crankshaft and a connecting rod, connecting the crankshaft to a crosshead. A piston rod connects a piston to the crosshead. The piston reciprocates in a gas compression cylinder. At least one pressure-drop module is positioned between the gas compression cylinder and a crosspiece guide. The piston rod extends from the gas compression cylinder through a pressure-drop chamber of the pressure-drop module. Also disclosed herein is a method of operating a reciprocating compressor.

摘要： The reciprocating compressor has a cylinder with a compression chamber where a piston can slide between a crank-side position and a head-side position; a piston rod is mechanically connected to the piston and during operation of the compressor, slides in a hole of the compression chamber; there is a small gap between the hole and the piston rod; in order to avoid leakage from this gap a jacket is arranged around the piston rod and is sealed on one side to the piston and on the other side to the cylinder at the gap.

摘要： The disclosure concerns a waste heat recovery cycle system and related method in which a Brayton cycle system operates in combination with a Rankine cycle system. The Brayton cycle system has a heater configured to circulate a fluid, namely an inert gas, in heat exchange relationship with a heating source, such as an exhaust gas of a different system, in order to recover waste heat from such different system by heating the inert gas. The Rankine cycle system has a heat exchanger configured to circulate a second fluid, in heat exchange relationship with the inert gas of the Brayton cycle system to heat the second fluid while at the same time cooling the inert gas. The second fluid can be selected among fluids having a boiling point at a temperature lower than the temperature of the inert gas from the expansion unit/group in the Brayton cycle system.

摘要： A turbomachinery plant is conceived to maximize the power generated by an electrical reversible machine when works as a generator, by reducing the power absorbed by a compressor connected to the electrical reversible machine. The compressor is connected to an antisurge circuit included in the turbomachinery plant, as well as to a suction unit by a first line and to a gas collection unit by a second line and the turbomachinery plant comprises a gas depressurizing compressor so that, when in use, an amount of gas sucked by the gas depressurizing compressor moves from the antisurge circuit to the gas depressurizing compressor and the compressor rotates encountering less resistance and absorbing less power and the power generated by the electrical reversible machine is maximized.

摘要： A rotary machine assembly for a turbomachine, such as a rotor, having a rotor wheel where a plurality of circumferentially spaced female dovetail slots are obtained. The rotary machine assembly also comprises a plurality of blades. Between each blade and the adjacent one there is an interface angle. Each blade comprises a male dovetail, configured to fit with a corresponding female dovetail slot of the rotor wheel along an insertion direction. The female dovetail slots are shaped so that the insertion direction of each male dovetail is convergent with the rotation axis of the rotor wheel, so as to form with it an insertion angle, so as to insert gradually all the male dovetails into the female dovetail slots and packing them also gradually. A method for assembling a rotary machine assembly, which does not require any specific tool, is also disclosed.
