Embodiment Construction

[0024] exist figure 1 A known sealing system 1 is shown in , for the pressure to be sealed relative to the working medium p d , For example, the axially reciprocating piston rod 3 of a cylinder pressure-sealed piston compressor. The sealing system 1 is arranged in a stationary 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 inserted, for example, as is well known, in a preassembled state and is fastened, for example, by means of a plurality of screws distributed over the circumference in the housing part 2 . In the example shown, the sealing system 1 comprises two L-shaped chamber disks 4 , 5 , which are separated axially by a separating disk 6 in the exemplary embodiment shown. Naturally, however, other embodiments are also conceivable, for example with T-shaped separating discs. A flange can also be arranged radially on the outside on the chamber disk 5 , by means o...

Abstract

High temperatures of the sealing medium occur in a hydraulic sealing medium barrier for sealing a piston rod of a piston compressor, and there is the risk of soil and abrasion being deposited there and interfering with the function of the seal. To prevent this, a sealing configuration (1) which is provided for circulating sealing medium through an outlet line (11) for sealing medium which is connected to the recess (10), and a circulating device (13) is provided, with which the sealing medium is circulated through the recess (10) while maintaining the pressure (poil) of the sealing medium through the inlet and the outlet line (7, 11).

Description

technical field [0001] The invention relates to a sealing system for sealing a reciprocating piston rod of a piston compressor, the sealing system comprises a first sealing element and a second sealing element, the first and second sealing elements are arranged axially at intervals in the sealing system In the gap, wherein, in the sealing system, an input pipeline for a sealing medium under pressure communicating with the gap is provided, and the pressure of the sealing medium is greater than the pressure to be sealed, and the sealing element is arranged to pass through the sealing The pressure of the medium bears against the axial ends of the recess and against the piston rod, respectively, so that the pressurized sealing medium is enclosed in the recess by the sealing element. Background technique [0002] In a piston compressor, a space with high pressure (such as the operating pressure in the compressor's cylinder) is sealed along the piston rod against a space with low ...
