Abstract

The invention relates to high pressure membrane compressors with hydraulic drive and reduces the labor costs of production by improving processability. The drive cavity 2 communicates with the submembrane cavity 5 via interconnected radial and axial channels 6 and 7, respectively, formed in housing 1 and distributing the pressure of the driving fluid evenly over the entire area of the membrane 4. Performing distribution channels 6 and 7 directly in housing 1 without the distribution disk allows to reduce the assembly operation, eliminate the seal of the distribution disk and precise processing for it, which leads to an increase in processability and, consequently, to a reduction in labor cost on production. 2 Il.

Description

1

The invention relates to compressor engineering and can be used in high pressure membrane compressors.

The purpose of the invention is to reduce labor costs for production by improving manufacturability,

FIG. 1 shows a hydraulically actuated membrane compressor; FIG. 2 is a section A-A n5 of FIG. one.

The hydraulically actuated membrane compressor includes a housing 1 with a driving space 2, a limiting disk 3, and a membrane 4 clamped between the disk 3 and housing 1 with the formation of a submembrane cavity 5. In housing 1, radial b and axial 7 channels are made. Channels 6 and 7 are interconnected and communicate the drive cavity 2 directly connected to the radial channels 6, the submembrane cavity 5 directly connected to the axial channels 7, the radial channels 6 are plugged with plugs 8. Separate radial channels b can communicate with communication channels cut off by safety and suction hydraulic valves (not shown). The restrictor disk 3 is equipped with a suction and pressure nozzles with valves 9 and 10, and the plunger 11 of the hydraulic actuator is installed in the housing 1.

Diaphragm compressor with hydraulic actuator works as follows.

When the plunger 11 moves from the top dead center, the membrane 4 bends in the direction of the housing 1. The suction process takes place in the working chamber. When the plunger 11 moves to the top dead center, the driven fluid from the drive cavity

2 through the radial channels 6 and then through the axial channels 7 enters the submembrane cavity 5. uniformly acting on the membrane 4, which bends in the direction of the limiting disk 3. The compression and pressure processes occur in the working chamber. Further, the processes are repeated cyclically.

The implementation of distribution channels 6 and 7 directly in the housing 1 without the presence of a distribution disk improves the manufacturability of the design as a result of the absence of the need for precise processing of the seating surfaces of the distribution disk and housing 1 and surfaces for sealing the distribution disk and a separate assembly operation. In this case, the uniform distribution of the pressure of the drive fluid on the membrane 4 is maintained.

In addition, the design reduces the size of the compressor, since it does not require the placement of the seals for the distribution disk.
