Description

The utility model relates to compressor engineering and can be used to create an electromagnetic compressor with reciprocating pistons.

Known electromagnetic compressor containing a housing, a stationary coil, a movable rectangular anchor, a spring, a working body in the form of pistons and cylinders. (SU395615A1, 08/22/73). The disadvantage of an electromagnetic compressor with a reciprocating piston and its coaxial mounting with a movable armature is the lack of limitation of the stroke of the working body and the adjustment of its magnitude, and the compressor operation at variable loads can cause the armature to beat on the compressor body, which reduces the reliability of the design as a whole, and relatively low efficiency due to increased losses in the steel sections of the magnetic circuit of an electromagnetic motor made of solid material.

These drawbacks are partially eliminated in the design of an electromagnetic compressor containing a housing with a cylinder with a piston and an electromagnetic drive in it, made in the form of a twisted magnetic circuit with a power winding and a spring-loaded layered armature interacting with it, connected to the piston. (SU1267042A, 10.30.86. An undoubted advantage electromagnetic compressor with reciprocating movement of the working body is a relatively high efficiency due to the use of ferromagnetic tape in the design, however, awn manufacturing the armature as a frame filled with ferromagnetic ribbon, reduces the compressor manufacturing processability.

Closest to the claimed compressor (prototype) is an electromagnetic membrane compressor containing a membrane located in the housing with a rod, a core with poles placed on them by windings connected to an AC source, and an armature made in the form of a ring element. (SU1000595A, 02.28.83). The fundamental difference between the design of the prototype and the above is that in the prototype the compressor engine operates due to the transverse magnetic field, which allows you to clearly position the working body and prevent the working body from colliding with the compressor body part. However, such a compressor has a complex profile of the armature, made in the form of an annular element, which reduces the manufacturability of its manufacture, and relatively low efficiency due to the core made of solid material.

The objective of the proposed utility model is to increase the efficiency of the compressor while increasing the manufacturability.

This task and the technical result are achieved due to the fact that the electromagnetic membrane compressor containing a membrane with a rod located in the housing, a core with poles placed on them by windings connected to an alternating current source, and an armature interacting with it, ring protrusions are formed along the armature length with a step equal to the step of the diameter-conjugated annular protrusions formed at the poles of the core, and the anchor and the poles of the core are made of separate plates of electrical steel.

Figure 1 shows the design of the proposed electromagnetic compressor, figure 2 its cross section.

The electromagnetic compressor (FIG. 1) comprises a housing 1, a cylinder 2 with a piston 3 placed therein and a core 4 with poles 5, 6 (FIG. 2), with windings 7, 8 placed on them and spring-loaded elastic elements 9 interacting with them, 10 of the armature 11, rigidly connected by means of the rod 12 with the piston 3. Moreover, structurally, the working body of the compressor can be made both in the form of a piston, and in the form of a membrane. Figure 1 shows the implementation of the working body in the form of a piston.

The core 1, composed of plates of electrical steel, is made at the same time with the poles 5, 6 protruding inward. Ring projections are made along the entire length of the poles with equal pitch t. The inside of the poles 5, 6 is mated in diameter with the armature 11, also drawn from plates of electrical steel , along the entire length of which the reciprocal annular protrusions are made with a step t equal to the pitch of the annular protrusions at the poles 5, 6.

The electromagnetic compressor operates as follows.

In the initial state (Figure 1), the armature 11 is located between the poles 5, 6 so that its annular protrusions are at a distance equal to half the length of the mating annular protrusions of the poles.

When an alternating electric current flows through the windings 7, 8 connected to an alternating current source, an alternating magnetic flux is closed in the core 4, poles 5, 6 and the armature 11. Under the action of electromagnetic forces arising in the annular protrusions, and the elastic forces of the elements 9, 10, the armature 11 performs reciprocating motion relative to the fixed stator 1. Together with it, the rod 12 moves, causing periodic oscillations of the piston 3, which ensures the processes of gas suction and discharge .

Since the magnetic flux is variable, when the flux changes and it is equal to zero, the electromagnetic force applied to the armature 11 also becomes equal to zero. Due to the compression force of the lower spring-loaded elastic element 10, the armature 11 returns to its initial state before the arrival of the next current pulse.

Thus, during the period of the supply current, the armature makes one complete oscillation, which at a source frequency of 50 Hz corresponds to 3000 vibrations per minute. Changing the pitch τ of the ring protrusions at the armature 11 and the response ring protrusions at the poles 5, 6 of the core 4, allows you to change the amplitude fluctuations.

Changing the ratio of the size of the pole divisions allows you to adjust the stroke of the compressor working element.

It is assumed that the core and anchor are made of steel plates with a thickness of the size of the pole divisions. The proposed improvement allows to increase the efficiency of the compressor with a simultaneous increase in manufacturability, due to the reduction of heat loss from the action of eddy currents.
