Embodiment Construction

[0024] in figure 1 Shows a known sealing system 1 for the pressure to be sealed relative to the working medium p d For example, the cylinder pressure seals the axially reciprocating piston rod 3 of a piston compressor. The sealing system 1 is arranged in a fixed housing part 2 of the compressor, such as a compressor housing, and seals between the housing part 2 and the moving piston rod 3. The sealing system 1 is installed in a preassembled state, for example, as is sufficiently known, and is fixed in the housing part 2 for example by means of a plurality of bolts distributed on the circumference. In the illustrated example, the sealing system 1 includes two L-shaped chamber disks 4, 5, which are axially separated by a partition disk 6 in the illustrated embodiment. Naturally, other implementation structures such as T-shaped partition discs are also conceivable. A flange can also be provided on the cavity disc 5 on the outside in the radial direction, by means of which the fl...

Abstract

In a hydraulic sealing medium barrier for sealing a piston rod of a reciprocating compressor, high temperature of the sealing medium result, and there is the danger of dirt and abrasion debris depositing and thus impairing the function of the seal. According to the invention, in order to prevent this, a sealing assembly (1) is proposed, which, in order to recirculate sealing medium, provides a discharge line (11) for sealing medium, which is connected to the opening (10), and a recirculating device (13), by means of which sealing medium is recirculated through the opening (10) via the feed line and discharge line (7, 11) while the pressure (p0n) of the sealing medium is maintained.

Description

Technical field [0001] The invention relates to a sealing system for sealing a reciprocating piston rod of a piston compressor. The sealing system includes a first sealing element and a second sealing element. The first and second sealing elements are axially spaced apart in the sealing system. In the gap of the sealing system, the input pipeline for the sealing medium under pressure is provided in the sealing system, and the pressure of the sealing medium is greater than the pressure to be sealed, and the sealing element is arranged to pass the sealing The pressure of the medium abuts against the axial end of the gap and against the piston rod, respectively, so that the pressured sealing medium is enclosed in the gap by the sealing element. Background technique [0002] In a piston compressor, a space having a high pressure (for example, a working pressure in a cylinder of the compressor) is sealed with respect to a space having a low pressure (for example, atmospheric pressure ...
