A major manufacturer of hydraulic fracturing tools for the
oil and gas industry is using NVision's
HandHeld laser scanner to increase the performance and life of its products by
gaining a clearer picture of erosion patterns. The company previously used
ultrasonic sensors to measure discrete points in a gridded pattern after
erosion testing with proppant. The HandHeld Scanner provides a much clearer
understanding of erosion patterns by measuring millions of points and providing
a comparison of the geometry before and after testing with color deviation
models showing the amount of material that has been eroded in each area of the
tool. This information helps engineers gain an intuitive understanding of tool
performance, which in turn helps improve design and substantially increase tool
Hydraulic fracturing involves pumping a fracturing fluid
into a well bore at a high enough level of pressure to cause the formation to
crack, enhancing the flow of oil and gas from the formation to the well. A slurry
material called proppant, which commonly consists primarily of sand or ceramic
material, is then injected into the fracture to prop it open, thereby increasing
the flow of formation fluids. However, the proppant is highly abrasive and
erodes the casing and tools. After they have eroded to a certain point, the equipment
needs to be replaced, which is expensive in terms of labor and tool cost, but
most important delays the completion process.
After some investigation, the manufacturer decided to
perform the erosion measurements with the NVision HandHeld Scanner. A key
advantage of the HandHeld Scanner is that it is mounted on a mechanical arm so
it can move freely around tools of any size. The mechanical arm keeps track of
the scanner's location so all data is collected within the same coordinate
system. As technicians inspect the tool, the scanner generates a point cloud consisting
of millions points each with x, y, z coordinates and i, j, k vectors. The laser
scanner also provides accuracy to a few thousandths of an inch.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
