　　The security inspection machine is an electronic device that uses a conveyor belt to send the checked luggage into the X-ray inspection channel to complete the inspection. When the luggage enters the X-ray inspection channel, it will block the package detection sensor, and the detection signal will be sent to the system control part, generating an X-ray trigger signal, triggering the X-ray source to emit an X-ray beam.

　　The X-ray beam passes through the inspected objects on the conveyor belt, and the X-rays are absorbed by the inspected objects and finally bombard the semiconductor detector installed in the channel. The detector converts the X-rays into signals, and these very weak signals are amplified and sent to the signal processing chassis for further processing. After these signals are processed, they are displayed on the display screen.

　　”No matter how many layers a package has, X-rays can penetrate it and display the items in the package layer by layer.” Dangerous items are identified by different colors. Multi-energy colored organic matter is displayed in orange, inorganic matter is displayed in blue, and mixtures are displayed in green. High energy/low energy are switched to display. High energy displays metals, etc., and low energy displays non-metals. In the image display system, the X-ray sensor L-shaped photodiode array detector (multiple energies are optional), 12-bit depth, high penetration display increases the brightness of dark areas in the image, so that items hidden behind highly absorbent objects are clearly displayed. Low penetration display increases the contrast of low absorption (easy to penetrate) objects, making easy to penetrate objects clearer; therefore, the X-ray security inspection machine is not a decoration, but actually undertakes the work of protecting railway safety.

　　So how does the security inspection machine detect these dangerous items?

　　1. Image monitoring method

　　Image monitoring method directly determines the object from the X-ray image configuration. Therefore, whether the object is suspicious depends on the image on the monitor or display. Unusual objects or objects with different shapes that appear on the display or monitor should be considered suspicious objects. Objects that cannot be accurately identified should also be considered suspicious objects and need to be carefully investigated. The image can be located and analyzed as needed.

　　2. Color analysis method

　　The color analysis method is to identify the type of material based on the different colors that different materials show under the x-ray image. The various colors that appear on the monitor are a reflection of the density, quality and quantity of the object. Therefore, the quality of the object can be evaluated based on the depth of the image color.

　　Light yellow is generally the color of a single piece of clothing, thin plastic, and a small amount of paper.

　　Orange is generally the color of soap, soap, explosives, drugs, wood, leather products, etc.

　　Dark orange is generally the color of a large number of books, paper, RMB, high-concentration liquids, large bags of rice and flour, etc.

　　Blue is the color of inorganic substances such as copper, iron, and zinc. Thick cables, stun guns, bullets, gun barrels, guns, and knives show different shades of blue. Green is the color of mixtures, stainless steel products, cables, etc. show different shades of green. Red is the color of impenetrable objects, mostly heavy metals and thick objects.

　　When it comes to fastening and securing materials in construction, manufacturing, or DIY projects, the type of screw head plays a crucial role in determining the strength, durability, and reliability of the connection. Among the various screw heads available, the strongest is often debated, but a few contenders consistently rise to the top.As can be seen from the new data, stainless steel fasteners supplier The market influence is also growing, and the product share is also relatively increasing, which has great potential in the future. https://shwhardware.com

　　Geothermal heat pumps, also known as ground source heat pumps, are an efficient and sustainable solution for heating and cooling homes. They utilize the stable temperatures found underground to provide consistent and eco-friendly climate control. Let’s dive into how these systems work and why they are an excellent choice for both heating and air conditioning needs.In the industry, heat pumps for sale Has been a leader in the industry, but later came from behind but never arrogant, low-key to adhere to quality. http://mangoenergyheatpump.com

　　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.

　　”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/

　　security check

　　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.

　　security check

　　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.

　　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 is an extrusion deformation of larger workpieces and has a wide range of uses.For this reason, it can be speculated that non standard fasteners The market feedback will get better and better, which is one of the important reasons why it can develop. https://jieruifasteners.com/

　　1. What is cold extrusion

　　Cold extrusion is a processing method in which a metal blank is placed in a cold extrusion die cavity and, at room temperature, a punch fixed on the press is used to apply pressure to the blank to cause the metal blank to undergo plastic deformation to produce parts. Obviously, cold extrusion processing relies on the die to control the flow of metal and relies on the large-scale transfer of metal volume to form parts. In terms of extrusion equipment, my country has the ability to design and manufacture extrusion presses of various tonnages. In addition to using general mechanical presses, hydraulic presses, and cold extrusion presses, friction presses and high-speed and high-energy equipment have also been successfully used for cold extrusion production.

　　At present, cold extrusion technology has been widely used in industrial sectors such as fasteners, machinery, instruments, electrical appliances, light industry, aerospace, shipbuilding, and military industry, and has become one of the indispensable and important processing methods in metal plastic volume forming technology. 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).
