摘要： An improved apparatus and methods for recovering abrasive from an abrasive-laden fluid are shown and described. An abrasive-laden fluid handling device is coupled to a catcher tank to collect abrasive-laden fluid and transport it to a hydro-classifier. Wet recovered abrasive is discharged from the hydro-classifier and transferred to a de-watering device. The de-watering device removes water from the abrasive by decanting fluid and via use of an air eduction system. De-watered abrasive is then ejected from the de-watering device to a dryer unit, to be further dried and processed for reuse.

摘要： This invention relates to methods and apparatus for recovering abrasive for use with abrasive jet cutting systems. In one embodiment, an apparatus in accordance with the invention includes an abrasive-laden fluid handling device coupled to a catcher tank of an abrasive jet cutting system, a pre-classifier fluidly coupled to the abrasive-laden fluid handling device, a hydro-classifier fluidly coupled to the pre-classifier, a fine-particle separation tank fluidly coupled to a clarified-fluid flow outlet of the hydro-classifier, a wet abrasive receptacle positioned to receive a wet recovered abrasive discharged from the hydro-classifier, a de-watering device engageable with the wet recovered abrasive in wet abrasive receptacle, and a dryer unit. The abrasive-laden fluid handling device may include an abrasive-laden fluid conduit having a first end in fluid communication with the catcher tank and an abrasive-laden fluid outlet. Alternately, the abrasive-laden fluid handling device may include a fluid drive system. In another embodiment, a de-watering device includes a housing having a wet abrasive intake and a de-watered abrasive, and an eductor port situated along an abrasive travel path extending between the wet abrasive intake and the de-watered abrasive outlet, an eductor inlet coupled to the eductor port and coupleable to a source of eduction air, and a transport device. In a further embodiment, an apparatus includes an airflow control valve fluidly coupled to the eductor port and positionable in a first position to draw an entrained airflow from within the housing through the eductor port, and a second position to backflow the eduction air through the eductor port into the housing.

摘要： A seal carrier is provided for an ultrahigh-pressure fluid system having a plunger configured to reciprocate therein along a longitudinal axis when the ultra-high pressure fluid system is in operation, the seal carrier having an inner surface provided with a first portion configured to captively receive a seal, substantially preventing displacement of the seal in a direction substantially parallel to the longitudinal axis, and a second portion configured to circumferentially surround a bearing. The seal carrier is further provided with an outer surface having a recess formed along at least a portion of a circumference thereof, the recess at least partially positioned opposite the first portion of the inner surface along a lateral axis substantially perpendicular to the longitudinal axis.

摘要： An ultrahigh-pressure fluid system, such as an ultrahigh-pressure fluid pump, includes an improved dynamic seal assembly that can withstand pressures above 40,000 psi, and more preferably, pressures up to and beyond 87,000 psi. The dynamic sealing assembly includes a plastic seal having a bore through which the plunger reciprocates, and a bearing positioned adjacent the seal, also having a bore through which the plunger reciprocates. A seal carrier surrounds the circumference of the bearing and is subjected to a compressive force that is sufficiently high to circumferentially collapse the seal carrier in a radial direction against the bearing. This collapse of the seal carrier against the bearing causes an inner surface of the bore through the bearing to achieve substantially uniform contact with an outer surface of the plunger when the assembly is subjected to ultrahigh-pressure, thereby eliminating gaps that occur in prior art systems. By eliminating any gap between the seal carrier and the bearing, and between the bearing and the plunger, the present invention eliminates any pathway through which the seal might otherwise extrude, particularly when subjected to high pressures up to and beyond 40,000 psi, and more particularly, up to and beyond 87,000 psi.
