Abstract

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.

Abstract

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.

Abstract

The invention relates to an oil wiper packing (1) for a piston rod (2) of a crosshead piston compressor, and to a corresponding assembly method. The oil wiper packing has at least one chamber disc (3) having a chamber disc cutout (3a), wherein a wiper ring (4) is arranged in the chamber disc cutout (3a). At least two chamber discs (3, 5), which each have a chamber disc cutout (3a, 5a), are arranged in succession in a direction of extent (L), and a single wiper ring (4) is arranged in each chamber disc cutout (3a, 5a). It is particularly advantageous for each particular wiper ring (4) to have no play or only negligible play in the direction of extent (L) in the operating state, but to be arranged so as to be movable in the radial direction. To this end, it is necessary to set the play in a corresponding manner in the cold state during the assembly of the wiper rings (4). Such an arrangement allows advantageous wiping of oil, since in this way oil is prevented from spreading in the direction of extent of the piston rod.

Abstract

The linear bearing (3) comprises a plurality of concentrically arranged springs (2), each spring (2) being designed as a plate spring with a fixing part (2a) and a bore (2c) arranged in the center (Z). Each spring (2) also has a spring arm (2b) which emerges from the fixing part (2a) and ends in an end section (2g). The end section (2g) has the bore (2c), and the bore (2c) is concentric to the fixing part (2a). Each spring (2) has a direction of movement (B) which runs perpendicular to the fixing part (2a), and the springs (2) are arranged one behind the other in the direction of movement (B). The spring arm (2b) has a spring arm section (2ba) which runs concentrically with the bore (2c) and which extends along an angular range (γ) between 100° and 270°, preferably along an angular range (γ) between 180° and 300°. The fixing part (2a) is at least partly annular, and the spring arm section (2ba) has, in a radial direction with respect to the bore (2c), a width (2k) which is at least five times greater than the thickness (2i) of the spring arm (2b). The width (2k) of the spring arm section (2ba) is designed such that the spring arm section extends relative to the annular fixing part (2a) and the end portion (2g) while forming a lateral gap (2d).

Abstract

The oil control ring (1) comprises a retaining ring (2) and a scraper (3) having a scraper fin (3a), wherein the scraper (3) is arranged in the retaining ring (2) in such a way that the scraper fin (3a) is oriented towards the center (1a) of the oil control ring (1) in order to scrape oil on a piston rod (6). The scraper (3) comprises a plurality of scraper segments (3e) which are arranged in succession in the circumferential direction (1b) of the oil control ring (1), and the retaining ring (2) has a groove (2b) for accommodating the scraper segments (3a) in a positive manner, and the retaining ring (2) has an abutment point (2g). The retaining ring (2) forms at least one plastic first end face (2d, 2e) which is oriented towards the center (1a) of the oil control ring (1). The scraper (3) is made of a harder material than the plastic forming the first end face (2d, 2e), the scraping fin (3a) of the scraper (3) has a contact point (3c) oriented towards the center (1a) and the scraper (3) and the retaining ring (2) are adapted to each other in such a way that both the at least one first end face (2d, 2e) and the contact point (3c) can lie against the piston rod (6).

Abstract

The seal arrangement (1) for piston compressors comprises a deformable ring support (2) and a first and a second endless sealing ring (3a, 3b), wherein the ring support (2) has a longitudinal axis (L) which extends perpendicularly with respect to its circumferential direction, and wherein the ring support (2) has a gap (2i) with play in its circumferential direction, and wherein each sealing ring (3a, 3b) has a longitudinal axis (3c, 3d) which extends perpendicularly with respect to its circumferential direction, and wherein the sealing rings (3a, 3b) are arranged in such a way that the ring support (2) encloses them from the outside, and wherein the two sealing rings (3a, 3b) are arranged next to one another in the direction of extent of the longitudinal axis (L), and wherein the ring support (2) and the sealing rings (3a, 3b) are designed to be adapted to one another in such a way that the first sealing ring (3a) bears on one side against a first side wall (2d) of the ring support (2) and forms a first gap (S1) to the ring support (2) on the opposite side with regard to the longitudinal axis (3c) of the first sealing ring (3a), and wherein the second sealing ring (3b) bears in a diametrically opposed manner on one side against a second side wall (21) of the ring support (2) and forms a second gap (S2) to the ring support (2) on the opposite side with regard to the longitudinal axis (3d) of the second sealing ring (3b), wherein the first and second side walls (2d, 21) are arranged so as to lie opposite one another with regard to the longitudinal axis (L), with the result that the ring support (2) can in each case bring about a prestressing force (5a, 5b) on the first and second sealing rings (3a, 3b) respectively via the first and second side walls (2d, 21) respectively, wherein the prestressing forces (5a, 5b) extend in an opposed manner.
