Elevator control for inductor pump

摘要

An inductor pump system comprises a fluid activated ram, an inductor pump platen, a fluid activated motor and a fluid control. The inductor pump platen is driven by the fluid activated ram. The fluid activated motor is coupled to the platen. The fluid control comprises an inlet for receiving a source of pressurized fluid, a first circuit and a second circuit. The first and second circuits are configured to receive pressurized fluid from the inlet. The first circuit comprises a switching valve connected to the inlet; an actuator line connected to the ram and the switching valve; and a blow-off line connected to the inductor pump platen and the switching valve. The second circuit is connected to the inlet to receive pressurized fluid and to the motor.

1. A control circuit for an inductor pump, the control circuit comprising:
an inlet for receiving a pressurized fluid; a first fluid line comprising:
an upstream end connected to the inlet; anda downstream end; a first on/off valve connected to the first fluid line between the upstream and downstream ends; a second fluid line comprising:
an upstream end connected to the inlet; anda downstream end; a second on/off valve connected to second fluid line between the upstream and downstream ends; a switching valve connected to the downstream end of the second fluid line; a blow-off line extending from the switching valve; and an actuation line extending from the switching valve; wherein the switching valve toggles fluid flow to the blow-off line and the actuation line alternatively.
