BAFFLE SYSTEM FOR FLOWING PARTICULATES INTO A FRAC FLUID BLENDER
The density of slurries produced by mobile blender for injection into oil and gas wells is controlled using a microwave flow meter. Liquid having a known density is provided to the blender. The liquid is flowed through a conduit and discharged into a blending tub on the mobile blender. The amount of liquid introduced into the tub is measured with a liquid flow meter. Solid particulates having a known density are provided to the blender. The particulates are discharged into the tub by allowing them to fall into the tub from a conveyor on the mobile blender. The amount of the particulates falling into the tub are measured with a microwave flow meter. The flow of the liquid and the particulates are controlled in response to the measurements to blend a slurry having a predetermined density. The slurry is provided for injection into the well.
Frac pumps have valve bodies. The valve bodies comprise a head and a compressible seal. The head provides a valve surface adapted to engage the valve seat. The compressible seal is carried on the head radially inward of the valve surface and is adapted to engage the valve seat. It is mounted between the head and a valve guide having a plurality of legs. The face of the compressible seal has a slightly curved, convex sealing surface.

An embodiment includes a method of monitoring a fluid pump that includes receiving time domain measurement data indicating vibrations occurring in a fluid pump, and filtering the measurement data to remove measurement data components having frequencies below a threshold frequency, the removed measurement data components associated with cyclical motions of the fluid pump. The method also includes dividing the filtered measurement data into a plurality of subsets, each subset corresponding to a pump cycle, and estimating a peak count for each subset, the peak count being a number of peaks having an amplitude that exceeds a selected amplitude threshold, the amplitude threshold associated with impacts between internal components of the pump. The method further includes comparing the peak count with an expected peak count, and determining whether the pump is in a condition selected from at least one of a wear condition and a failure condition based on the comparison.
