摘要： A piston ring for a reciprocating compressor is disclosed, including a one-part annular sealing ring with an arcuate outer surface and having a gap between butt ends of the sealing ring. A joint seal seals the gap symmetrical, having two limbs that extend at both sides in the peripheral direction over an angular range of 20° to 180° and having a radially outwardly directed, arcuate limb outer face. The joint seal includes a contact part that extends at both sides in the peripheral direction and projects beyond the limbs in the axial direction. The sealing ring and the joint seal are adapted to each other such that, when assembled, the joint seal rests laterally against the sealing ring via a stop and runs along the gap and covers same in the peripheral direction.

摘要： Piston ring having an endless base ring and sealing ring have a radially outwardly directed base ring face side. The sealing ring has a radially inwardly directed, circularly running sealing ring inner side with three tangential cuts separating three sealing ring segments are arranged in a circumferential direction (U). The base and sealing rings are arranged in succession in a longitudinal direction (L). A top ring is arranged to adjoin the sealing ring having a top ring has a radially outwardly directed top ring outer side and a radially inwardly directed top ring inner side. The top ring has, on the side opposite the sealing ring, a radially running return flow channel extending radially, the sealing face side protrudes in a radial direction beyond the top ring outer side and the base ring face side. The base and the top rings have a greater tensile strength than the sealing ring.

摘要： An oil wiper packing for a piston rod of a crosshead piston compressor, and corresponding assembly method. The oil wiper packing has at least one chamber disc having a chamber disc cutout, wherein a wiper ring arranged in the chamber disc cutout. At least two chamber discs, each having a chamber disc cutout, are arranged in succession in a direction of extent (L), and a single wiper ring is in each chamber disc cutout. Each wiper ring has no play or only negligible play in the direction of extent (L) in the operating state but is movable in the radial direction. It is necessary to set the play in in the cold state during the assembly of the wiper rings. Such an arrangement allows advantageous wiping of oil, preventing oil from spreading in the direction of extent of the piston rod.

摘要： A method for monitoring the condition of a piston rod sealing system of a piston compressor, the system having at least two annular chambers arranged one behind the other in a longitudinal direction and each having a sealing element arranged therein. A piston rod running through the sealing elements and the annular chambers is moved back and forth in the longitudinal direction, sealed by the sealing elements. The system has an inlet side and an outlet side, between which a difference in pressure occurs, and said difference in pressure has static and dynamic pressure component. When there is leakage gas in the annular chambers, at least the dynamic pressure component of the leakage gas is measured in the piston rod sealing system. A change in the condition of at least one of the sealing elements is determined from a change in the dynamic pressure component as a function of time.
