Abstract

The invention relates to instrumentation, in particular to controls, and can be used to create stabilization systems in the moving elements of machines. The purpose of the invention is to improve the quality of stabilization of the mode of operation of compressors. The method of stabilizing the mode of operation of the compressor is to use a displacement sensor with a zero signal when combining the midpoints of the stator and the sensor rotor to control the compressor piston, which is located at a predetermined boundary of the dead zone. During compressor operation of another polarity, the signal from the sensor in the control circuit stops the supply of voltage pulses from the generator controlling the operation of the motor winding, and the piston moves with a predetermined limit. Sensor rotor, electric motor rotor and piston on one rod. As a result of the proposed method, the operation mode of the electromagnetic compressor allows operating the cylinder-piston group with high efficiency and long time. 1 il.

Description

The invention relates to the field of instrumentation, in particular to controls, and can be used to create stabilization systems in machines with reciprocating or any cyclic movement.

The aim of the invention is to increase the stabilization.

The drawing shows an electromagnetic piston compressor, the piston rod of which is connected to the displacement sensor rotor.

The compressor includes a piston I, a cylinder 2, a winding 3 of an electric motor, a rotor 4 of an electric motor, a spring 3, a retainer 6, a sensor stator 7, a rotor 8 and a sensor rod. The displacement sensor is designed so that the distance a between the centers of the rotor 8 and the stator 7 is equal to the distance from the end of the piston 1 at its neutral position to a predetermined boundary of the dead volume of the cylinder 2 or the rotor 8 of the sensor center with respect to the end of the piston 1 at a distance from equal to the distance d from the given boundary of the dead volume zone of cylinder 2 to the center of the stator 7 of the sensor and the rotor 8 of the sensor. The rotor 4 of the electric motor is connected through electrically insulating non-magnetic rod.

Stabilization is carried out as follows.

When control voltage pulses are applied to the winding 3 of the electric motor under the action of a pulse of electromagnetic energy 1x forces, the rotor 4 of the electric motor tends to move according to the arrow. In this case, the rotor 8 of the sensor begins its movement toward the middle of the stator 7, when their midpoints are combined, the piston 1 reaches the set boundary of the dead zone of the cylinder 2 of the compressor. Upon further movement in the generator control circuit, a signal of opposite polarity is sent from the displacement sensor, interrupting the generator control pulse. Under the action of the forces of the spring 3 of the rod, and with it the piston 1, the rotor 4 of the electric motor and the rotor 7 of the sensor do the opposite

movement until the next control pulse arrives from the generator.
