Reducing Machine Controller Design and Deployment

Machine design and deployment requires integration of various technologies such as controls, mechanics, vision, lasers, data acquisition, and software, to mention only a few. These mechatronic solutions usually target a specific purpose such as part manufacturing, marking, packaging, etc. Often the controller is a key focus in the design because it must connect and coordinate all of the processes on the machine. Using separate programmable logic controllers (PLCs) and motion controllers necessitates integration, which is costly and time-consuming. Using a single controller for the machine eliminates the need for integration and shortens design and deployment time and cost.

Reducing Linear Bearing Wear

To get the longest working life out of a linear bearing, keep it clean and well lubricated. This common-sense advice may sound easy enough to follow. Yet in the real world of round-the-clock, high-cycle manufacturing operations, bearings do get dirty and dry. And when either of these conditions happens, linear bearings will wear prematurely. In the worst-case scenarios, contamination and inadequate lubrication can create metal-on-metal contact between the bearing’s rolling elements and raceway. This can cause excessive wear in the form of denting, pitting, or galling results.

Hull-Cleaning Robot for Large Ships

Toxic paint is used on the bottoms of large ships to prevent fouling, which is when a biofilm layer develops, decreasing the ship’s efficiency moving through the water. To further complicate the matter, the paint must be blasted off and replaced every 5 to 10 years, at which time literally tons of toxic waste is produced and needs to be disposed of.

Rotating Machinery Analysis

Microstar Laboratories (Bellevue, WA) has announced the release of the Rotating Machinery Analysis module with software tools to facilitate mixed time measurements and rotation measurements of rotating machinery. The software enables time-based sampling or encoder-based sampling, or both at the same time. The module processes data captured by a fixed-rate, high-resolution sampling clock with software processing operating at continuously varying rates aligned to pulses from the encoder device. The processing uses DSP technology based on classical sampling theory.

Thermoplastic Pumps

Hayward Flow Control (Clemmons, NC) has released the T-Series Webster thermoplastic pumps. The vertical, seal-less, immersible pumps feature a single, non-coupled motor/impeller shaft with a proprietary shaft seal. The pumps are available from 1/3 HP to 1-1/2 HP, with standard and washdown motors, and in voltages of 115/230 and 208-230/460. Other features include 303 stainless steel shaft material and an extended shaft sleeve. Options include GFPP or PVDF pump head and impeller assembly, inlet screen, in-tank filtration, impeller trim variations, explosion-proof motors, 575V motors, and S-J type electrical cord.
