摘要： An automated abrasive control system 100 is provided for controlling abrasive flow in a pneumatic abrasive blast pot 110 having at least one blast hose 116 (shown coupled to a blast nozzle 115). The pneumatic abrasive blast pot 110 is used for the cleaning and preparation of surfaces in readiness for the application of paint systems or other surface treatment processes. A plurality of sensors accurately measures values of the system operating parameters such as air pressure, temperature, humidity, and abrasive flow rate. The automated abrasive control system 100 includes an abrasive flow sensor 120 for measuring abrasive flow rate through the at least one blast hose 116, an abrasive metering valve 114 for controlling abrasive flow rate through the at least one blast hose 116, and a controller 112 configured to receive a signal from the abrasive flow sensor 120 and actuate the abrasive metering valve 114 based on a set of predetermined conditions such as nozzle size and abrasive media and combinations thereof in order to maintain the abrasive flow rate within an optimum abrasive flow rate range.

摘要： The present disclosure relates to abrasive material delivery systems for liquid jet cutting systems. The abrasive material delivery systems can include a valve configured to adjust inflow of abrasive material into the abrasive material delivery system from a source of abrasive material. The systems can include a chamber downstream of the valve and configured to receive the inflow of abrasive material. The systems can include a metering component configured to control an outflow of abrasive from the chamber to a cutting head. In some embodiments, the systems include a sensor configured to monitor movement of a top surface of a portion of abrasive material within the chamber as the top surface moves through the chamber; and a processing device operably connected to the sensor and configured to determine an abrasive flow rate through the metering component based on a speed of the top surface as monitored by the sensor.
