【标题】Practical Preservation Strategies for Valves


【类型】 期刊

【作者】 Cortec Corporation

【摘要】 (P&GJ) - Ball valves, gate valves, globe valves, butterfly valves, check valves and valve assemblies: all these are common and critical components in the oil and gas industry. Their job of regulating hazardous fluid flow in pipelines and piping systems underscores the importance of keeping them in peak operating condition. Unfortunately, one of the most common enemies of valve integrity is rust, which can attack and deteriorate valves during hydrotesting, shipping, and layup. The following tips from Cortec Corporation provide preservation guidelines during the three main phases of a valve's non-operational life-cycle. Phase 1: The Long Haul - Before a pipeline () or plant starts operating, thousands of components must be fabricated, assembled, and shipped to the construction site. Valves must be hydrostatically tested by the valve manufacturer to ensure no leaks.

【标题】Green machine tools' help make energy-saving air blowers


【类型】 期刊

【作者】 Colin Granger

【摘要】 There is a parallel between a new, low-pressure air compressor (blower) manufactured by the British firm Lontra (www.lontra.co.uk) and the Japanese-built turn-mill centre from Okuma that is used to machine one of Lontra' s key blower components. Both pieces of equipment have been engineered for maximum environmental sustainability while operating and both use Industry 4.0 connectivity to make them even more efficient. Okuma's UK and Ireland sales agent is NCMT Ltd, Coventry (www.ncmt.co.uk). Describing the multi-tasking turn-milling application, NCMT said: "At the core of Lontra's LP2 Blade Blower is its custom-engineered, patented Blade Compressor positive displacement technology, a novel rotary piston and cylinder design that delivers oil-free air or gas at pressures up to about 1 bar. The LP2 Blade Blower unit is used in many industries ranging from water aeration, where electricity savings of up to 34% have been noted, through to food, pharmaceutical and other pneumatic conveying applications, for which similar energy reductions have been recorded. These blowers are also found in cement manufacture, mining, and power generation.

【摘要】 Compressor technology has been evolving since the earliest days of air conditioning; the time has come to embrace the latest generation. It was one spring day in the mid-1970's that I tagged along with an experienced refrigeration technician on a residential service call. My task that day, as a neophyte helper, was to carry tools and equipment in and out of a fabulous mansion located just north of downtown Toronto.

【标题】Airmaster Cooling Range - now with Portable Air Purifier, Dehumidifier and Evaporative Coolers

【参考中译】Airmaster Cooling Range -现在配备便携式空气净化器、除湿器和蒸发冷却器

【类型】 期刊

【作者】 Lisa Peake

【摘要】 Airmaster is long established as a key brand in Air cooling with comprehensive ranges of table and floor fans, encompassing both premium and economy options to key products. Aircon units have been added in recent years, with 2023 enhancements to both 9,000 and 12,000 BTU units now with quieter operation and complete with wifi app controlled versions. There are three further major additions for this year. The first edition is a portable air purifier. This 22w floor standing unit, for room sizes from 17 to 30m2, features a high efficiency filter and clear LED display. A similarly portable compact Dehumidifier is next. Designed for quiet operation, this 12 litre refrigerant and auto frost detector is fitted with omni-directional wheels for ease of movement. The final new addition is a floor standing Evaporation Cooling Tower, cooling air by water evaporation. With three fan speeds this unit has a remote control seven-hour programmable timer, with an auto pump shutdown protection when waterless.

【摘要】 Every car has one. Every driver uses one. But they have a much bigger effect on a car's performance than many realise. Here's the PVW's Gearbox Guide... There are some things in the car world you just take for granted. Gearboxes are the perfect example. Every driver understands how to use them and most car enthusiasts understand what gear to be in for best performance in a given situation. But how many people can actually explain what a gearbox does? Not many, we bet. But that's perfectly understandable, as not only is it quite a hard thing to understand. But on the face of it, understanding gearboxes doesn't seem to be any big advantage to even the most ardent car tuning fan.
