Problems solved by technology

This main problem is caused by mechanical contacts in the reversing point of the reciprocating piston and thus increased component loading and noise emission which are considered problematic - especially in installations in residential areas nearby situations - and require additional soundproofing

Embodiment Construction

[0027] figure 1 A piston compressor 100 according to the invention is schematically shown in a preferred embodiment, which is suitable for carrying out the method according to the invention.

[0028] Piston compressor 100 (also referred to as a reciprocating piston compressor in the form shown) includes a cylinder 110 within which a reciprocating piston 111 may move back and forth or up and down. In principle, such a piston compressor could be multi-stage, ie there could be several cylinders 110 shown with reciprocating pistons 111 . Therefore, the following description in relation to the cylinder with the reciprocating piston then also applies to the other cylinder with the reciprocating piston.

[0029] The piston compressor 100 is driven by a hydraulic drive, which here includes a hydraulic piston 120 . The hydraulic piston 120 is driven by a runner (hydraulic crankshaft drive) with a shaft 121 with a suitable connecting rod. Rotation of this shaft 121 as indicated by th...

Abstract

The invention relates to a method for operating a piston compressor (100) having a reciprocating piston (111) in a cylinder (110), wherein an inlet valve (112) and an outlet valve (113) are provided in the cylinder (110) on the side of a medium (b) which is to be compressed and conveyed, wherein the reciprocating piston (111) is moved to and fro by way of a hydraulic drive (120, 121) with a hydraulic piston (120) with the use of a hydraulic medium (a) in a first volume (141), with which the reciprocating piston (111) is loaded on the side of the hydraulic drive (120, 121), wherein, if required, hydraulic medium (a) is fed into the first volume (141) and / or is discharged from the first volume (141) in a manner which is dependent on a position of the hydraulic piston (120) and / or a rotational angle (phi) of a shaft (121) which is provided for moving the hydraulic piston (120) in relation to a position (x) of the reciprocating piston (120) and / or a pressure (p) in the first volume (141),and to a piston compressor (100) of this type.

Description

Background technique [0001] The invention relates to a method for operating a piston compressor and to a piston compressor. [0002] Compressors are used in particular to compress gaseous media. The efficiency of conventional piston compressors is very strongly influenced by the presence of residual volume or dead space in top dead center. Gases or media in this region lead to possible re-expansion and a reduction of the inflow delivery volume during the inhalation cycle. This area is unavoidable in order to compensate for manufacturing tolerances and thermal expansion of the components and subsequently to avoid mechanical contact of the reciprocating piston in the compressor with the cylinder head. The channels for the suction and pressure valves (ie, inlet and outlet valves) add to this negative effect. [0003] Reducing this dead space reduces re-expansion of the remaining medium and thus increases the delivery volume or efficiency of the compression process. So-called ...
