Zusammenfassung:A blasting system includes a pressure vessel, water pump, blast circuit, motor, orifice valve, and controller. The pressure vessel is configured to contain a pressurized blast media slurry. The water pump pumps water from a water supply to the pressure vessel. The blast circuit delivers the pressurized blast media slurry received from the pressure vessel. The motor drives the water pump. The orifice valve regulates a rate of flow of the blast media slurry to the blast circuit. The controller provides control commands to the water pump or the orifice valve based on a blast media flow rate set point and at least one sensed operating parameter.
