What Stands Behind Ultrasound Technology

Ultrasonic method offers fast, high quality cleaning process and washes hard to reach areas. This ensures the replacement of highly toxic and expensive flammable solvents with plain water. With the help of high frequency ultrasonic vibrations you can clean an automobile carburetor or injectors within as little as a couple of minutes.

The reason for the acceleration in the treatment of cavitation lies phenomenon of emergence of tiny gas bubbles in liquid. These bubbles implode (explode) and create powerful hydrostreams that wash away all the dirt. With this principle in mind, large manufacturers, like UK-based Hilsonic, produce industrial ultrasonic cleaners (washing machines), baths and small cleaning devices. Ultrasound cleans metals from polishing pastes and precious stones from polishing places, it can easily clean the pipes of complex shapes. In addition to cleaning, ultrasound is capable of producing small burr removal and offer polishing of considerable quality.

Medicine & microbiology

Sonication in liquid media kills microorganisms and therefore it is widely used in medicine and microbiology. There is another implementation of the ultrasonic cleaning – the purification of smoke particles in the air. It will also use ultrasound effect on fog and smoke. The particles in the ultrasonic field are beginning to move, collide and stick together, then they are deposited on the walls. This phenomenon is called ultrasonic coagulation and is used to fight with fog on the ground, on the roads and seaports. (more…)


Industrial Lighting: Revolutionizing Industry By Industry

Industrial LED lighting is a decent energy-saving alternative to traditional incandescent lighting fixtures or discharge lamps. Industrial LED lighting boasts high light outputs with much lower power consumption, stability in almost any operating conditions and ability to easily withstand voltage fluctuations. When using LED lamp for industrial lighting you not only save on electricity, but also on the number of light points, cables and power machines. Industrial LED lighting fixtures do not contain mercury and do not require expensive disposal.

Industrial benefits

Why do commercial organizations make their choice in favor of LEDs technology? According to Metcraft Lighting manufacturers, a UK-based manufacturer concentrating its efforts on led street lights production, there is a good bunch of reasons for a business to join the LED race.

Thus, the maximum protection against dust and moisture and physical impact resistance are among the most vital industrial aspects. The degree of protection for industrial lighting fixtures is estimated at IP 65; they can be installed in areas with humidity above 98%, as well as in areas with high dust and extreme temperatures.

Resistance to voltage drops in the network is another dignity: the lamps are equipped with high-quality drivers, so that LED lighting industry operates stably in the range from 160 to 285 V.

The lenses allow to adjust the angle of the beam; thanks to them increases the possibility of using LED lamps in industrial lighting, for example, you can hang them to great heights, highlight any particular object, etc. (more…)


The Essential Technological Aspects of Flanges Production

Flanges represent flat or rectangular rings with evenly spaced holes for bolts and studs that are vital for a strong and tight connection of pipes, microwave waveguides and pipe fittings. Flanges are used for joining components to each other, connection with the machinery, apparatus and vessels, as well as for the connection of shafts and other rotating parts. Flanges are primarily designed for usage in pairs.

Flanges can be elements of pipes, fittings, shafts, housing parts, etc. These components in the form of individual parts are often welded or screwed to the endings of the parts. The shape of the sealing surface of the flange in the pipes depends on the pressure of the medium, profile and gasket material. Smooth surface with sealing gaskets made of cardboard, rubber and paronite are used at pressures up to 4 MPa (40 bar), the surface with a projection on one flange and hollow on the other with ANBO-metallic gaskets and paronite are used at pressures up to 20 MPa (200 bar), while flanges with a conical sealing surface are taken advantage of at pressures above 6.4 MPa (64 bar).

The material used for the manufacture of such parts is steel type 45 – high quality structural carbon steel. Nickel informs steel corrosion resistance, while high strength and ductility increase hardenability. Sulfur in its turn is considered to be harmful impurity, as it increases the abrasion steel reduces fatigue resistance and reduces the corrosion resistance. Phosphorus is also harmful impurities. Chrome is the cheapest and most abundant element, which increases the hardness and strength, decreases ductility and slightly increases the corrosion resistance. The large amounts of chromium make the steel stainless and provide stability of magnetic forces; copper increases the corrosion resistance.

Processing of metals is carried out under certain conditions. The set of indicators describing the conditions of the process of cutting is referred to as cutting conditions. Metal cutting is necessary to maintain proper regimes under which the power of the machine and the resistance of the cutting tool are used with maximum efficiency, high quality treatment provided, the highest performance and safe working environment are ensured.

The main cutting indicators include speed – V, supply – S and cutting depth.

Cutting speed V (m/min) is peripheral speed (m/min) of the most remote points from the axis of rotation of the tool of the cutting blade.

Supply, or S, is the feed path traversed by the tool relative to the workpiece (or vice versa) per unit time. Supply is measured in millimeters per minute (mm / min) or by one revolution of the workpiece or tool (mm/rev).Cutting depth is the thickness of the workpiece material (mm) cut off in one stroke.

The technological aspects mentioned are calculated by experts at production facilities. Thus, e.g. Alexandercomley, a reputed firm specializing in flanges manufacturing, creates a number of technological process documents, verified by engineers and equipment operators prior to integrating the process into production.

Top 3 Herbal Remedies for Depression

According to a fresh publication by Natural Health care Hub, St. John’s wort finds itself comfortably on top among the most efficient herbal remedies for depression. Its flowers are filled with red oily substance called hypericin – an all-sufficient component that shouldn’t be combined with pharmaceutical medicines (backfire results are possible). The reason for that is the influence of hypericin on the liver. The powerful ingredient activates the metabolism of cytochrome P-450 that dramatically speeds up the drugs processing and removal from the body. The standard dose of hypericin equals 300 milligrams of 0.3 per cent extracts of St. John’s wort three times a day.

Herbal remedies for depression – schizandra

Chinese magnolia vine, or schizandra, is another solid rep of herbal remedies for depression. The herb helps during severe stress conditions: it improves mood, helps to get rid of boredom. The action of schizandra supports the adrenal glands (helping to deal with stress inside the body, as the adrenal glands produce adaptogens). Another advantages of the drug are increased libido and impressive detoxification properties. A standard dose equals 500 mg twice a day (morning and afternoon). The medication should not take be taken in the evening, since this interferes with the initial goal – to act on the adrenal glands during periods when they are most active, in the daytime. (more…)


Safety At Workplaces – The UK Way

The United Kingdom adopted a safety in the workplace strategy for the period up to 2010 and prolonged the program with a range of adjustments. The strategy is based on the fact that the safety and health of workers is a cornerstone of a civilized society. In aspiration to reduce the level of deaths and serious injuries on the production by 10%, the level of occupational diseases by 20%; loss of working time due to illness by 30%, a new strategy has been introduced and implemented almost absolutely successfully. Within the framework of the new strategy, the government ensures advanced accessibility to submitting accidental claims, as well as dozens of other personal injury cases, e.g. whiplash claims.

The strategy is based on the understanding that, since the adoption of the law on the protection of workers’ health and safety in 1974 the world has changed dramatically, so the necessity to modernise the system of risk management emerged naturally. The UK houses a good range of large firms (less than half the country’s workforce is employed in large organizations), and a significantly increased number of small businesses: more than 90% of the 3.5 million enterprises have less than 10 people employed; moreover, the country faced an increase in the number of workers employed in part-time work, while women now make up half of the workforce.
