Abstract
An intensifier pump system includes a supply pump for delivering fluid products at an intermediate pressure. The products are delivered to one or more intensifier pumps that take advantage of hydraulic intensification to expel the product at high pressures to assure continuous product deployment in various systems. After an extension cycle in one of the intensifier pumps, product is delivered from the supply pump at a pressure sufficient to retract the intensifier pump and fill the chamber with fluid.
Claims41
An intensifier pump system for the delivery of material, the pump system comprising:
- a supply pump that delivers material to the system;
- a first intensifier pump that receives the material front the supply pump;
- a second intensifier pump coupled to the first intensifier pump so that material delivered under pressure from the first intensifier pump to the second intensifier pump causes the second intensifier pump to refract and fills a first intensifier barrel associated with the second intensifier pump with the material;
- a first controllable valve that selectively delivers the material from the supply pump to the first intensifier pump when the first controllable valve is open;
- a first sensor that determines a position of an actuator within the first intensifier pump;
- and
- a first controller that opens the first controllable valve when an output of the first sensor indicates the actuator is near the end of an advance cycle and closes the first controllable valve when the output of the first sensor indicates the actuator is near the end of a retraction cycle.
