This work presents the results of complex research of changes in the hydraulic, stress-strain state and dynamic characteristics of the double-entry single stage pump (specific speed nq=55) in the case of introduction of splitter blades in the basic design are presented in this paper. Since the splitter blades modify flow within the blade-to-blade channel, […]
Predictive analytics can help companies identify equipment problems before they happen, keeping productivity high and maintenance costs low.
Background The International Submarine Races (ISR) is a competition in which teams race “wet” submarines. A “wet” submarine is an internally flooded, fully enclosed, vehicle in which the pilot(s) must breathe from a SCUBA apparatus [1]. The racecourse is a 100 yard straight sprint. The submarines compete in four categories: 1 and 2 person propeller, […]
By Chett Norton, C.E.T. and Sylvia Flegg, Triangle Fluid Controls Visually examine and clean flanges, bolts, nuts and washers and make sure to replace any defective components, if necessary. Lubricate bolt threads, nut threads & facing, and washers. Install new gasket (Do not reuse old gaskets or use multiple […]
Brushless DC electric (BLDC) motors have been in use for nearly 50 years, but have only recently been employed in smart actuation. Their adaptation is key to improving process control and plant safety systems. Safety and efficiency are critical in the control of plant systems, as each field device is expected not only to meet […]
APPLICABLE INDUSTRIES Chemical Processing WHY IS SEALING HYDROGEN FLUORIDE A CHALLENGE? Because of its harsh nature, hydrogen fluoride is a difficult chemical to seal. If leaked, in any volume, manufacturers must immediately alert an emergency response team. Gaskets for hydrogen fluoride systems must be constructed from materials capable of providing a reliable, leak-free seal and […]
In the past, hydrogen peroxide bipropellant rocket engines were reserved for limited performance applications such as propulsion for rocket-assisted take-off (RATO) or sounding rockets due to the use of pressure-fed propellants or low-performance turbopump cycles. However, research performed at Purdue University has indicated silver screen catalyst beds used to decompose hydrogen peroxide can operate at […]
Over the years, there have been a variety of ways to monitor asset health, but only recently have technologies like wireless connectivity, artificial intelligence (AI) and predictive algorithms taken these abilities to new heights. Today, companies have deeper insights into how their equipment performs; by using these insights they can make more informed decisions to […]
When it comes to pumps, there are many challenges associated with precious metal mining applications. For instance, there is a high degree of difficulty in handling abrasive paste with varying density, over long distances and without frequent breakdowns. Optimised pump selection for safe and responsible transfer of paste and tailings has never been more important, […]
Once the decision to automate has been made, there is a wide — and often confusing — variety of actuators from which to choose. This paper is designed to make all these decisions easier by providing a quick-reading overview of: The key factors to consider when making the decision to automate. The most common types […]
