METHOD FOR AUTOMATICALLY ADJUSTING AND STABILISING THE VOLUME RATE OF A VIBRATION PUMP IN DIFFERENT OPERATING CONDITIONS AND A VIBRATION PUMP FOR CARRYING OUT SAID METHOD

摘要

The invention relates to vibration pumps with an electromagnetic drive. The result is obtained by stabilising a ferroresonance voltage on the electromagnetic drive coils and by modifying the voltage thereon according to a pressure. The inventive method consists in converting the series circuit of a vibration pump and a capacitor into a ferroresonance parametric oscillation circuit, in winding coils (8) with the condition that a core is saturated and in adjusting a voltage by modifying a gap in the core according the change in pressure. For this purpose, shock-absorbing and elastic suspensions (11, 12) are designed in such a way that an average gap in the core is reduced by 30-40% at a full pressure. The inventive vibration pump for carrying out said method comprises an independent body (3) with the capacitors (4, 5) which are connected in parallel and in series to the coils (8). The coils (8) are designed with the condition that a core (6) is saturated, and the rigidity (11) of the surface area of the shock-absorbing suspension (12) corresponds to the claimed ratio.
