”Big bags, small bags, please go through security check!” Security check is always an essential step when you travel by high-speed rail, airplane, or subway. I wonder if you have ever been interested in this security check machine. What can the staff see on the screen? How do they quickly identify the items in the suitcase? Today, let the editor reveal this secret for you.So we can draw a preliminary conclusion, security screening machine It is helpful to the needs of the industry market and social development. https://secuzoan.com/

　　How does the security inspection machine work?

　　Generally speaking, the machine that conveys and inspects luggage is called an X-ray luggage inspection machine. As the name suggests, the security inspection machine uses X-rays to inspect luggage.

　　X-rays are short-wavelength electromagnetic waves that can penetrate objects. The penetration of X-rays varies depending on the thickness, density and material of the object.

　　Everyone should know that X-rays in hospitals are also used by doctors. The penetration rate of X-rays varies according to the density of the structure and tissue. The penetration rate is high in loose areas and low in dense areas. The bones of the human body are denser than the skin and flesh tissue. Therefore, when X-rays are irradiated to the human body, the outline of the bones will be displayed more clearly on the screen.

　　The same is true for the security inspection machine that checks luggage. The penetration rate of X-rays on different objects is different. When the suitcase passes through the security inspection machine, the X-rays penetrate the suitcase and display the outlines of different objects on the display screen.

　　At this time, some friends may feel confused: X-ray imaging should be black and white, so why can security inspectors identify different objects so quickly?

　　This question really hits the nail on the head. If you have ever looked at the security check display screen, you will find that the image on it is in color, not black and white.

　　security check

　　Normally, the color of the image formed by X-rays on the film is indeed black and white, just like the X-ray photos in the hospital. The reason why a color image appears on the security screen is that the computer calculates and converts the projection intensity of the X-rays. This is also to make it easier for security personnel to quickly distinguish different objects in a short period of time.

　　Normally, orange represents organic matter such as liquids and sprays; blue represents metals and various controlled knives; and heavy metals or lead, which can completely absorb X-rays, will be displayed in black.

　　Now you should know why the staff will immediately notice and ask you to take out a small pair of scissors in your suitcase; and the water in your backpack will also be asked to take out and drink a sip.

　　CNC machining, also known as computer numerical control machining, is a manufacturing process that utilizes computer digital control technology to operate machine tools for part machining.By comparison, it can be seen that 304 stainless steel screws It has certain advantages and great cost performance. https://shwhardware.com

　　It has high precision and repeatability, and can process complex geometric shapes and high-precision parts. By using a pre written CNC program, the motion trajectory, cutting speed, feed rate, and other parameters of the tool on the workpiece are controlled to achieve precise cutting processing.

　　CNC machining can be applied to various materials, including metals (such as aluminum alloys, stainless steel, titanium alloys, etc.), plastics, composite materials, etc. It plays an important role in many industries such as aerospace, automotive manufacturing, medical devices, and electronic equipment.

　　Its advantages include improving production efficiency, reducing manual operation errors, shortening production cycles, and achieving complex shape processing.

With the advancement of science and technology and the continuous improvement of product technical requirements in the automobile, motorcycle, household appliances and other industries, cold extrusion production technology has gradually become the development direction of refined production of small and medium-sized forgings.

　　2. What is cold heading

　　Cold heading is one of the new processes of metal pressure processing with little or no cutting. It is a processing method that uses the plastic deformation of metal under the action of external force, and with the help of a mold, the metal volume is redistributed and transferred to form the required parts or blanks. The cold heading process is most suitable for the production of non standard fasteners such as bolts, screws, nuts, rivets, and pins. The commonly used equipment for cold heading is a dedicated cold heading machine. If the production volume is not too large, it can also be replaced by a crank press or a friction press.

　　Cold heading technology has high productivity, good product quality, and greatly reduces material consumption, reduces production costs, and improves working conditions. Therefore, it is more and more widely used in mechanical manufacturing, especially in the production of standard fasteners. Among them, the most representative products produced by multi-station cold heading machines are bolts, screws and nuts.

　　3. Are cold heading and cold extrusion the same thing?

　　Cold heading and cold extrusion are basically deformation processes under the same conditions, but they are different in operation. Cold heading is a forging deformation of smaller workpieces and is often used in the fastener industry. Cold extrusion, on the other hand, is an extrusion deformation of larger workpieces and is widely used; cold heading is equivalent to a branch of cold extrusion. Simply put, in the process of making bolts, hexagonal head forming is cold heading, and rod diameter reduction is cold extrusion (positive extrusion). Non-cut hexagonal flange bolts (multi-station forming) have both cold heading and cold extrusion. The front shaping of hexagonal nuts is only cold heading, and the hole extrusion in the back process is cold extrusion (positive and negative extrusion).

　　What is a Geothermal Heat Pump?

　　A geothermal heat pump is a system that leverages the earth’s natural heat to provide heating, cooling, and often hot water for residential and commercial buildings. Unlike conventional HVAC systems that rely on outside air temperatures, geothermal systems use the relatively constant temperature of the ground as a heat source in winter and a heat sink in summer.

　　How Do Geothermal Heat Pumps Work?

　　1. Ground Loop System:

　　Closed-Loop Systems: These are the most common and involve a loop of piping buried in the ground or submerged in water. The loops can be installed horizontally, vertically, or in a pond/lake.

　　Open-Loop Systems: These systems use groundwater from a well or surface body, which is returned to the source after heat exchange.

　　2. Heat Exchange Process:

　　Heating Mode: During winter, the fluid in the ground loop absorbs heat from the earth. This heat is then transferred to the heat pump unit inside the building. The heat pump compresses the absorbed heat to a higher temperature and distributes it through the building’s ductwork or radiant heating system.

　　Cooling Mode: In the summer, the process is reversed. The heat pump extracts heat from the indoor air and transfers it to the cooler ground via the ground loop. This removes heat from the home and effectively cools it down.

　　3. Distribution System:

　　Once the heat is extracted from the ground and conditioned by the heat pump, it is distributed throughout the home via traditional ductwork or a radiant floor system.

　　Benefits of Geothermal Heat Pumps

　　1. Energy Efficiency:

　　Geothermal heat pumps are significantly more efficient than traditional heating and cooling systems. They can achieve efficiencies of 300-600%, meaning they can produce 3 to 6 units of heating or cooling for every unit of electricity consumed.

　　2. Environmental Impact:

　　By using renewable energy from the earth, geothermal systems reduce reliance on fossil fuels and decrease greenhouse gas emissions. They are a greener choice for sustainable living.

　　3. Cost Savings:

　　Although the initial installation cost of a geothermal heat pump can be higher, the system pays for itself over time through lower operating costs. Homeowners can save up to 70% on heating, cooling, and hot water bills.

　　4. Longevity and Durability:

　　Geothermal systems have fewer moving parts and are sheltered from outdoor elements, leading to longer lifespans. The underground loop systems often come with warranties of 50 years or more.

　　In today¨s fast-paced digital world, having a reliable and efficient power adapter is essential. As devices become more sophisticated, the demand for high-quality USB wall chargers has surged.
