PUMPS, PUMP ASSEMBLIES, AND METHODS OF PUMPING FLUIDS

摘要

The present disclosure relates to a system and method for pumping a feedstock slurry through a device. The system includes a pressure pump, a first sensor, a second sensor, a controller, and a control valve. The pressure pump includes a plunger configured to pressurize the slurry to a first pressure prior to the slurry entering the device. The first sensor is configured to sense a second pressure of the slurry entering the device. The second sensor is configured to sense the position of the plunger. The controller is configured to determine a change of position of the plunger based on the sensed position of the plunger and to control the movement of the plunger by setting a plunger mode based on the second pressure of the slurry and the change of position of the plunger. The control valve is configured to control the flow rate of the slurry through the device.

1. An apparatus configured to pump slurry into a device, the apparatus comprising:
a plunger configured to pressurize the slurry to a first pressure prior to the slurry entering the device; a first sensor configured to sense a second pressure of the slurry entering the device; a second sensor configured to sense the position of the plunger; and a controller configured to 1) determine a change of position of the plunger based on the sensed position of the plunger, and 2) control the movement of the plunger based on the second pressure of the slurry and the change of position of the plunger.
