Spray nozzle for liquids. home workshop

Home Workshop

Mortars, lubricating oils, protective fluids, paints, lacquers - many of today's "poured" materials require special spray tips.

The original nozzle for these purposes was proposed by the participants of the NTTM of the Syzran Plastics Plant. Its appearance may even be surprising: the supply hose ends with a metal plug. However, upon closer examination, you can see that the cork is split: it consists of two symmetrical halves. If they are separated, the inner glass-shaped cavity formed by them will open.

Spray nozzle for liquids
Spray nozzle: 1 - half of the body. 2 - nose part, 3 - parting plane with a channel, 4 - cavity

How does such a nozzle work? The liquid to be sprayed is fed into the body of the nozzle installed in the nozzle under pressure through the narrow channel of the tip. From here, it enters the expanding dead-end part of the cavity, as if being locked in this closed volume. In this case, a high pressure of the liquid is created in the "glass", which begins to burst the ground halves of the "cork". A micro-slit with a cross section of 0,01-0,02 mm is formed, into which the liquid breaks out with great force: the spraying is highly directed, economical and ultra-precise. Such a nozzle not only improves the quality and efficiency of work, but also provides considerable savings.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Philips BDM4UP 3275K monitor with MultiView 15.07.2015

Philips has introduced the BDM3275UP ultra-high resolution monitor with a diagonal of 32 inches.

The novelty is made on the IPS-AHVA matrix. The resolution is 3840 x 2160 pixels, which corresponds to the 4K / Ultra HD format. Brightness is 350 cd/m2, contrast ratio is 1000:1 (dynamic contrast ratio is 50:000). The panel features a 000ms response time (1ms with SmartResponse Technology); viewing angles horizontally and vertically reach 12 degrees.

The monitor, according to the manufacturer, provides a crystal clear image thanks to UltraClear technology. Designed to eliminate flicker, FlickerFree uses an innovative way to adjust brightness for a more comfortable viewing experience.

The MultiView function allows you to connect two signal sources at once and display several windows at the same time. For example, the image can be displayed from a desktop computer and a laptop.

The SmartErgoBase allows you to adjust the height, tilt and swivel. The display orientation can be changed from traditional landscape to portrait.

Among other things, it is worth highlighting the presence of stereo speakers, a USB 3.0 hub, D-Sub, DVI, DisplayPort and HDMI interfaces. Dimensions are 742 x 657 x 270 mm (with stand), weight - 10,9 kg.
