Systems and methods to monitor, detect, and/or intervene relative to cavitation and pulsation events during a hydraulic fracturing operation

A hydraulic fracturing control assembly to detect cavitation associated with operating one or more hydraulic fracturing units, the hydraulic fracturing control assembly comprising:

• one or more pump sensors to generate one or more pump signals indicative of one or more of pump discharge pressure, pump suction pressure, pump speed, or pump vibration associated with operation of one or more hydraulic fracturing pumps associated with the one or more hydraulic fracturing units;
• one or more blender sensors to generate one or more blender signals indicative of one or more of a blender flow rate of a blender or a blender discharge pressure of a blender;
• and
• a controller in communication with one or more of:
• the one or more hydraulic fracturing units,
• the one or more pump sensors, or
• the one or more blender sensors,
• the controller configured to:
• (a) receive one or more of:
• pump signals indicative of one or more of pump discharge pressure, pump suction pressure, pump speed, or pump vibration associated with operation of the one or more of the hydraulic fracturing pumps, or
• blender signals indicative of one or more of the blender flow rate or the blender discharge pressure;
• (b) (i) combine one or more cavitation values to determine a combined cavitation value, (ii) compare the combined cavitation value to a threshold cavitation value, and (iii) when the combined cavitation value equals or exceeds the threshold cavitation value, generate one or more cavitation notification signals indicative of detection of a cavitation occurrence associated with operation of the one or more hydraulic fracturing pumps;
• and
• (c) (i) count detected cavitation occurrences to determine a cavitation occurrence count, and (ii) thereafter, when the cavitation occurrence count is equal to or exceeds a threshold cavitation occurrence count, cause reduction of one or more of the pump flow rate of the one or more hydraulic fracturing pumps or the blender flow rate of the blender.
