Kaeser Compressors’ Omega G Series gas-tight rotary blowers feature double piston ring, hardened-steel gas and oil seals for reliable sealing and long service life. Seal vents may be piped back to suction or purged for single envelope, gas tight operation. The input shaft double lip seals with oil barrier prevent air ingress as well as fugitive gas emissions.
A steamy CDSolution Source for Steam, Air, and Water Systems provides relevant information on hundreds of related products in nine sections. The free CD devotes more than 20% of its space to engineering guidelines for steam conservation, condensate recovery, and draining liquids from compressed air and other gases.
Cooking oil controversyI am writing regarding the ReaderForum submission, "Consider the codes" (PE, January 2001, p 7).In the part about using cooking oil to stop evaporation of water in traps, the letter's author makes a fundamental logic error in interpreting the plumbing code. I do not have a copy of that code so I am assuming that he quoted all relevant sections accurately in making his de...
The 400 Series conveyors combine a low profile of 3 inches with load carrying capacities to 1,000 lb., and speeds of up to 2,000 fpm to satisfy material handling requirements. These conveyors are ideal for transporting heavy loads in tight quarters. Belt widths of up to 60 inches are available, in lengths to 100 feet.
Rustlick biostable semi-synthetic cutting fluids enable manufacturing plants to consolidate to one universal fluid. They are available in a non-chlorinated version – Ultracut 370R - or a chlorinated version – Ultracut 375R. The versatility of the fluids allow them to be used for both machining and grinding operation while providing optimum performance for a wide range of ferrous and...
Network grounding systemsA 60-p catalog covers copper and mechanical grounding components for network applications. The publication provides features, benefits, and complete specifications, including materials, dimensions, sizes, part numbers, and illustrations. Information charts and a cross-reference guide are included in the literature.
Properly sized, designed, and installed bridge and gantry cranes dramatically increase production, significantly reduce material handling costs, and substantially lower the risk of employee injury. A properly maintained crane lasts at least 20 yr, could reach 50 yr or more, and occasionally outlives the structure or company originally housing or using the equipment.
Key conceptsShort-term errors or long-term practices can cause boiler failures.Low-water trip switches should be checked regularly and never bypassed.Poor feedwater quality can cause corrosion and contamination.HVAC/SafetyRegard for personnel safety is an item that is first and foremost in the design, construction, operation, and maintenance of industrial manufacturing facilities.
From datalogging to supervisory control and data acquisition (SCADA), plant processes and maintenance functions frequently require collecting, analyzing, trending, and archiving data from multiple sources. One application is collecting temperature data to find hot spots on a boiler. Another is collecting flow and pressure to troubleshoot flow valves in the field.
