Abstract

The invention relates to electromagnetic membrane compressors and allows for improved volumetric performance and increased reliability. The axially movable measles (I) 5 is hermetically mounted in the housing (K) 1 with the formation of two oppositely spaced two-step membrane blocks. The membrane 6 divides one of the blocks into chambers 7 and 8 of the first and second steps, and the membrane 9 divides the other block into chambers 10 and 11 of the first and second steps. Chambers 7 and 10 communicate respectively with chambers 11 and 8 of the opposite blocks through channels 19 and 18, which are made in fixed rods 17. Membranes 6 and 9 are fixed in the center motionless with the help of rigid centers 12 on

Description

The invention relates to a compressor design and can be used in membrane compressors with an electromagnetic drive.

The purpose of the invention is to improve the volumetric characteristics and increase reliability.

The drawing shows the compressor, a longitudinal section.

Electromagnetic diaphragm two-stage compressor contains case 1, made in the form of a hollow cylinder of diamagnetic material, equipped with covers 2. On case 1 there are two electromagnetic plugs 3 and 4, and inside case 1 there is a ferromagnetic shaft 5. axially movable The ends of the core 5 are provided with recesses that, with the covers 2 and the parts of the housing 1, form two two-layer membrane blocks, which are opposedly located in the housing 1, one of which is divided by the membrane 6 into chambers 7 and 8 of the first the second stage and the other membrane 9 is divided into chambers 10 and 11 of the first and second stage.

The membranes 6 and 9 have rigid centers 12 and are fixed on the periphery of the ends of the bark. 5. In the bark 5, discharge channels 13, 14 and 15 are made with pressure valves 16 of chambers 8 and 11 of the second stage. Fixed rods 17 with channels 18 and 19 are fixed on rigid centers 12 of membranes 6 and 9 and covers 2. Canl 18 communicates chamber 10 of the first stage of one block with chamber 8 of the third stage of an opposed block, and channel 19 reports the chamber 7 of the first stage of another block with the camera 11 of the second stage of the opposedly located block. The suction valves 20 and 21 of the chamber 8 and 11 of the second stage are respectively located in the channels 18 and 19 of the fixed rods 17 from the side of the hard center 12, and the discharge valves 22 and 23 to the measures 7 and 10 of the first stage are located respectively in the channels 19

and 18 fixed rods 17 from the side of the covers 2. The suction valves 24 and 25 of the chambers 7 and 10 of the first stage are located in the covers 2. In the housing 1 there is a discharge nozzle 26,

Electromagnetic diaphragm two-stage compressor operates as follows.

When an electrical impulse is applied to

coil 3 is moving to the left. At the same time, in the chamber 10 of the first stage, a suction process takes place, and in the chamber 7 of the first stage - discharge, in the chamber 11 of the second stage - suction from the chamber 7, and in the chamber 8 the second

steps — gas compression; and at the moment the injection channel 14 is connected to the injection pipe 26 — injection and supply of compressed gas to the consumer. When applying an electrical pulse to the coil 4

Measles 5 move to the right. In this case, in chambers 7, 8, 10, and 11, processes similar to those occurring during the movement of the core 5 to the left occur. Then the cycle repeats.

The implementation of the housing 1 of diamagnetic material increases the performance of the compressor, improving the electromagnetic interaction of coils 3 and 4 with the core 5. Due to the presence of two coils 3 and 4, located in the immediate vicinity of the core 5 interacting with them and installed with the possibility of alternating interaction up to the extreme positions with kor 5, the last soveri.aet full stroke.

in which two working processes are performed simultaneously (suction and injection) in two blocks, i.e. simultaneously in four working chambers, improving the volumetric characteristics of the compressor. The fastening of the membranes 6 and 9 along the periphery of the end surfaces of the moving in the guides (in the cylinder of the housing 1) core 5, and the rigid centers 12 of the membranes 6 and 9 on the fixed rods 17, reduces the dynamic loads of the membranes and the stress that occurs in the material of the membranes, which increases service life and reliability of the compressor.
