System for monitoring machine vibration

Applicant: Université de Reims Champagne-Ardenne, France
This invention relates to a device for monitoring the vibration generated by a bearing of a machine formed by two coaxial races - an outer race and an inner race, with one fixed with respect to the frame of a machine and the other rotating. At least one rolling element, trapped between the races, is able to move. The device has at least one (non-conductive) means of positioning, which is mounted on an element (and in contact with an element of the bearing). This positions a conductive element to form the first plate of a capacitor (which is part of a capacitive sensor) at a distance from a conductive part of a race of the bearing, forming the second plate of the capacitor. The means of positioning is secured to a partitioning unit so as to create an insulating medium between the two plates.

EA Technology opens offices in the USA to grow partial discharge market

The UK’s EA Technology Group has opened offices in Florida and Oregon, USA, by acquiring No-Outage Electrical Testing Inc - a power engineering services company that has been a successful distributor for two years.
The move is designed to accelerate the ‘roll-out’ of EA Technology’s latest techniques for non-invasive condition assessment of medium voltage (MV) equipment across the USA.
Based in Capenhurst, EA Technology has offices in Australia, United Arab Emirates and China, together with 36 international distributors. Global sales of the group’s UltraTEV products for measuring partial discharge (PD) activity in MV equipment have increased more than 1300% in the last three years, says the company.
Don Genutis, President, No-Outage Electrical Testing, said: “We have no doubt that PD measurement is the most important technique available for identifying faults in MV equipment before they lead to failures, and that EA Technology produces the best PD test equipment in the world.”
The company will continue to trade as No-Outage Electrical Testing in the immediate future, but eventually will change its name to EA Technology USA.
Robert Davis, Chief Executive Officer, EA Technology, added: “Our alliance with No-Outage is perfect. They are service-based people who know exactly what US customers want from non-invasive equipment testing, and we have the technologies that will enable them to deliver it.”
EA Technology has more than 40 years’ experience working with MV assets and in the 1970s its scientists were among the first researchers to recognise the importance of transient earth voltage (TEV) effects.
First appearing in 2003, EA Technology’s UltraTEV instruments represent a step change in PD measurement, because they measure effects deep in the insulation, as well as surface emissions. The range has since grown from hand-held ‘first pass’ PD detectors, to instruments for investigating PD activity in detail, up to fully automatic Web-enabled systems for continuously detecting, locating, measuring, analysing and reporting PD activity in hundreds of pieces of MV plant simultaneously.
Genutis has been a NETA certified technician for 15 years and has 25 years of practical field and laboratory electrical testing experience. He co-founded No-Outage Electrical Testing to focus on new inspection technologies that can be used while equipment remains in service. The company is based in Florida and also has offices in Oregon on the West Coast.

Wireless leak-detection system - Patent Abstract

Applicant/Inventors: J.D. Ghazarian, T. Ruggieri and A.N. Balaster, USA
A supervised wireless leak-detection system forms the subject of this patent. It has a leak detection sensor unit, which is capable of transmitting a uniquely coded signal in response to a detected leak; a supervised wireless valve-control transceiver unit with a means of receiving the coded signal; and a transmitter for feeding this signal within the system. Also discussed is a valve shut-off mechanism that is linked to the valve-control transceiver unit. This shut-off mechanism has a motor attached to the valve, which creates a rotation pulse that is used to close and open the valve. A sensor and processor detect and count the motor rotation pulses when the valve is being closed or opened. This processor functions in a set-up procedure to memorise (learn) the motor rotation pulse count that is required to close or open the valve. Upon receipt of the uniquely coded signal <em dash> in response to a detected leak <em dash> the processor applies power to the motor to close the valve. The motor is controlled in such a way that it stops turning the valve in response to a motor-rotation, pulse-count number, which is substantially equal to a previously stored number that is needed to close or open the valve. A digital, voice, or SMS text message phone dialer dispatches the detected leak signals, and notifies monitoring personnel. The supervised leak detection and damage prevention system is illustrated in the accompanying figure. The wireless leak-detection unit (10), using a battery or A/C supply (12), or another source of energy such as solar power, is equipped with a sensor (14) that is capable of detecting a variety of substances, such as water, gas and petroleum, and a built-in transmitter which conveys the detected signals via an antenna (11). The leak-detection unit is installed mainly in buildings; homes; factories; open field applications, such as irrigation plants, petroleum facilities and pipelines - where pipes and fittings may leak. As illustrated in the diagram, when the sensor (14) unit detects a leak, the transmitter conveys the unique coded signal (containing information from the leak detection unit), and an on-board LED (13) flashes to indicate that a leak has been detected and the wireless transmission has been successful. The valve-control unit (30) is contained in a housing. It is powered by an A/C mains supply (66) or a battery (27) and has a motor (32) and gear (34). These are equipped with a sensor to detect shaft rotation and provide the processor (35) with corresponding electrical pulses. The processor sends power to the motor to operate the attached valve (38), and count the motor or gear turn-cycle pulses, and store in memory the count required to close and open the valve.

Mobile milling machine repairs large flange in-situ

UK global bolting and engineering technology firm Hydratight Ltd reports that it has saved chemicals and manufacturing company Huntsman money and time by using a computer-controlled tool to repair, in-situ, a large reactor-vessel flange.
Hydratight was performing bolt tensioning and ultrasonic measurements on a reactor at the Huntsman facility on Jurong Island, Singapore. Testing identified an issue with 90-mm (3.5-in) studs on a special 500-mm (20-in) flange on the reactor. The bolt failed to reach its required 40 000 psi stress level because of damaged threads.
Huntsman engineers confirmed earlier findings through further pressure testing that was performed on the reactor. Hydratight engineers were asked to assess the way in which the repair could be carried out. A proposal was made to use the company’s GeniSYS 220CNC - a 3D mobile milling machine - to bore out the damaged threads to 102 mm (4 in), then use reducers to restore the threads to 90 mm (3.5 in).
“Though simple in theory, such a job could have been very difficult in practice,” commented Hydratight’s Mark Foggin.
“The repair had to be extremely accurate - which is not really possible using conventional equipment, especially under site conditions and on such large bores. To get it wrong would have meant an even greater and more dangerous, potential for failure.”
“But we have seen the GeniSYS do some amazing work in worse circumstances in the past, so we knew we could complete the operation safely and efficiently, and meet the level of accuracy set by Huntsman.”
The machine and Hydratight specialist Rick Betteley were flown out to the plant and machined five new holes in the space of a few hours - during one shift - with the help of local colleagues and Huntsman staff. The stepped-down studs were fitted and bolt tensioned, and the repair was tested ultrasonically.
“The vessel passed all the company’s tests and is now back in full operation,” continued Foggin.
The cost of the repair was only a third of that of a new reactor - not including the massive associated costs of shutdown and replacement.
“Huntsman staff were so pleased they immediately asked us to re-cut threads on two more reactors within the next six months - saving a huge amount of money and time in the process,” added Foggin.
