Description

FIELD OF THE INVENTION This invention relates to compressors and pumps, primarily diaphragm electrically operated reciprocating pumps.

The purpose of the invention is to increase the efficiency by increasing the stroke of the core in relation to the stroke of the working body.

This goal is achieved due to the fact that the measles are spring loaded relative to the working body, which is mounted with the possibility of reciprocating movement relative to the core.

This goal is also achieved due to the fact that the compressor is provided with a guide rod mounted coaxially with the core and the stem, with an axial hole being made in the core, and the free end of the shaft being installed in the latter.

The drawing shows an electric compressor, General view.

The electric compressor consists of a housing 1, a stator part of the electric actuator 2, a guide 3, a movable part of the electric actuator 4, buffer springs 5, 6, 7. A rod 8 is clamped between the buffer springs 6 and 7, on which the elastic membrane is fixed 9. On the limiter cover 10 discharge 11 and suction 12 valves are located. The cover 10 and the membrane 9 form a working cavity 14, to which the valves are connected. The membrane 9 is fixed to the rod 8 by a screw 13. The frequency of mechanical vibrations of the mechanical system is natural. is close to the frequency of the supply network, therefore, when applying alternating or pulsed voltage to the windings of the stator part 2, the movable part 4 oscillates along the guide 3 with a large amplitude. Synchronously, the rod 8 moves with it, but with a small amplitude, because the farther from the movable end of the spring (or a series of consecutively installed springs) and closer to the fixed, the smaller the amplitude of the coil of the spring. The natural frequency of the springs themselves is much higher than the frequency of the measles-pru00 system

Zhina, because their mass is many times less. Poet; Moreover, their own frequency characteristics of the springs do not significantly affect the movement of the shields. Change the relative length and stiffness of the springs 6 and 7. You can get a different combination of the amplitudes of the moving part and the rod. The amplitude of the rod 8 will always be less than the amplitude of the movable part 4. The rod drives a membrane, which in its oscillatory motion in combination with valves provides a compressor cycle.
