Abstract: The oil quality in an oil reservoir of a pump is monitored using the disclosed oil-monitoring sensor. The oil-monitoring sensor includes a first capacitive portion for measuring oil level and a second capacitive portion for measuring dielectric constant of the oil. Changes in dielectric constant of the oil are indicative of degradation of the quality of the oil (e.g., due to contaminants, oxidation, etc.) So oil-monitoring sensor is used to indicate various parameters about the oil quality to an operator. Using the disclosed sensors, the quality of the lubricant and/or cooling oil used by the pump may be monitored without needing to be present at the pump, or without needing to access the interior of the pump (or oil reservoir).

Abstract: A system for monitoring a hydraulic fracturing pump includes a first sensor configured to measure a discharge fluid pressure of the pump, a second sensor configured to sense a displacement of a crankshaft of the pump, a processor communicatively coupled to the first and second sensors and configured to analyze the sensor data and determine a cycle count, duty cycle, and operating hour value for the positive displacement pump, and a display coupled to the processor configured to display the cycle count, duty cycle, and operating hour value.

Abstract: A fluid delivery device for a hydraulic fracturing system includes a fluid conduit having a fracking fluid outlet configured to be fluidly connected to a well head for delivering a fracking fluid to the well head. The fluid conduit includes a base fluid inlet configured to be fluidly connected to the outlet of a frac pump such that the fluid conduit is configured to receive a flow of base fluid from the frac pump. An injection system is fluidly connected to the fluid conduit downstream from the base fluid inlet and upstream from the fracking fluid outlet. The injection system is configured to be fluidly connected to a material source. The injection system is configured to inject at least one material of the fracking fluid from the material source into the fluid conduit downstream from the frac pump to generate the fracking fluid within the fluid conduit.

Abstract: A valve assembly for a fluid end of a frac pump includes a valve seat, a generally cylindrical and elongated metal core, a dampener layer bonded to the metal core, a metal outer layer bonded to the dampener layer. The metal core, dampener layer, and metal outer layer form an elongated valve body having a generally cylindrical extended portion that extend beyond the valve seat. The metal core, dampener layer, and metal outer layer of the valve body also form a generally conical lower portion that has a sealing surface configured to meet and engage with the valve seat.
