Enjoying The Benefits Of Ultrasonic Cleaning

Various metal products production technologies require practicing special and delicate approaches as for the cleaning of the details’ surfaces. However, the form of many products doesn’t allow effective internal surface degreasing; dealing with blind holes or threaded connections in the conventional washers is another challenge. Fortunately, the panacea is already there and available for large-scale production facilities – ultrasonic baths not only cope with the degreasing of parts quickly and efficiently, but also enable you to get rid of rust, a variety of adhesives, lapping lubricants (including the ones based on graphite) and even grinding and polishing pastes based on chromium oxide.

How it works?

Washing in ultrasonic baths is carried out through placing the items in a liquid which often is an aqueous solution of detergent-based surfactants. Unlike washing products with blasting chambers, cleaning with ultrasonic baths provides an ability to take advantage of water-soluble detergents with different pH, from acid to strongly alkaline. This allows the use of ultrasound equipment for the removal of carbon from the molds and dies, cleaning oxides, degreasing of metal and other materials.

Ultrasonic cleaning method is based on the phenomenon of cavitation. Powerful ultrasonic transducers acting on the fluid, creating the field of variable pressure, the density of which varies with the master oscillator frequency. The nodes of cavitation are constantly formed, collapsing steam bubbles and forming bursting effect, which in turn affects the pollution, increasing the effectiveness of detergents in the tens or hundreds of times. The lower the frequency is, the larger the size of the cavitation bubbles and thus they are more powerful, however, the effect can damage the precision parts, such as printed circuit boards or polished surfaces if applied to the frequency of 40 kHz. Another weak point is considerable energy consumption and quite complicated infrastructure maintenance.

In addition to ultrasonic power use, baths themselves deal with ultrasound – the approach used to enhance the effect of degreasing and cleaning of metal parts with complex shapes (for example in the processes where solvents are used, as well as submersible with jet washing machines).

Ultrasonic equipment

Ultrasound systems can be incorporated in existing lines degreasing parts, as well as for the organization of pre-metal degreasing in electroplating lines. Ultrasonic washing allows for additional cleaning of parts and longer-lasting impact electrochemical degreasing baths clean.

Modern ultrasonic cleaner equipment for degreasing based on technologies developed by Hilsonic is considered to be one of the best choices as for price value ratio. Hilsonic Company is investing heavily in researching, modernizing and testing, which results into decent quality ultrasonic cleaning devices. Thus, the piezoceramic transducers used on Hilsonic devices allow a 97% efficiency to convert the current frequency into vibrational energy. Ultrasonic washing is no longer an exotic cleaning method, and mostly due to the pioneers and evangelists of the method, putting significant effort into making the technology cost-efficient and, of course, effective. Thus, ultrasound method pays for itself within the first year of use at medium-scale enterprises.

Overhead Cranes Inspection Peculiarities & Real Use Cases

To date, the issues of safe operation and examination of industrial safety of lifting equipment is absolutely vital since it falls in the focus of many supervisory authorities. One of the components of the examination of lifting devices is a significant technical diagnosis of overhead cranes to identify hazardous operational defects. In this article, prepared in close collaboration with GMH Company, Granada Material Handling, specialised in overhead cranes and gantry hoist production and maintenance and being one of the UK industry leaders, we consider the experience of the application of acoustic emission control method for diagnosing metalwork lifting structures.

From the experience of operating gantry cranes it is known that the a result of the impact of various adverse factors forms dangerous fatigue failures. The identification of such defects in the course of the examination of cranes traditional methods of control over existing methods is extremely problematic, especially in remote or hard to reach areas. On this basis, to identify hazardous operational defects and reliable assessment of the technical condition of the crane, the companies may want to make use of the acoustic emission method. This method makes it possible to record wave elastic stresses arising from internal local dynamic restructuring of the material structure. These processes are accompanied by the accumulation of structural damage, the formation and growth of cracks that eventually lead to a limiting conditions and structural failures. Read more »

Street Lighting Evolving: The LED Shining

Economical street lighting today is a necessary measure not only because it allows you to pay less for electricity, but also because the natural energy resources are being depleted so quickly that their shortage is related to one of the most pressing environmental issues of our time. Metcraft Lighting manufacturers, a noteworthy UK-based manufacturer and a led street lights pioneer, the company that managed to press for 567% energy consumption savings, is now reaping the fruits of the innovations. So what is the secret behind LED success?

 

LED lamps manufacturers like Metcraft offer a wide range of products for street lighting niche, having various modifications built for different purposes. With their help illuminating the streets, roads, yards, plots of land, parking lots, gas stations, bridges is always a walk in the park mission. Products that work on the basis of light-emitting diodes have a high enough value, so you need to choose them carefully, paying attention to even the little things, after all, depends on them time and quality of the lamp.

A rational approach to the selection of LED street lamps

First of all, industry experts recommend to pay attention to the aspects mentioned below.

Purpose of the LED lamp. The choice in favor of a lamp is worth doing with the features of the area it will cover in mind. Before you choose a particular model, you need to calculate the area dimensions, which can reveal the ideal type of lamp and a suitable modification. So much for the lighting of roads, gas stations one should buy console LED lamps, characterized by the wide power curve of the luminous flux that help to achieve uniform illumination. Power LED lamps for street, which is planned to replace the conventional lantern, must be not less than 90W (120W for some cases). To illuminate individual municipal, industrial and other facilities, as well as yards, gardens of private homes it is reasonable to make use of fixtures without an optical system with the curve of the radiation flux of type ‘D’.
