A lot of people don't know how to choose the concrete pump types. Actually, it is not difficult. You can choose the suitable model correctly, as long as you consider the concrete project object, the characteristic, the required quantity of conveyance, the conveyance distance, the concrete construction plan and the concrete pump form.

1. Types and structures of buildings

The performance of the concrete pump truck varies with the type of the truck. When selecting the machine type, the type and structure of the building, construction technical requirements, site conditions and surrounding environment should also be considered besides the amount of concrete pouring. The main performance parameters of the selected concrete pumping equipment supplies should be consistent with or slightly larger than the construction needs. If the capacity is too large, the utilization rate is low. If the pump truck is too small, it will not only fail to meet the construction requirements but also accelerate the loss of the concrete pump truck.

2. Adaptability to construction

The concrete pump truck has flexibility. The higher the boom height, the larger the casting height and the placing radius and the stronger the construction adaptability. Therefore, high - arm concrete pump truck should be selected as far as possible in construction. The concrete pump truck with arms length of 28 -- 36m is a mass product on the market, accounting for about 75%. Long - arm concrete pump truck will be the main type of construction. In addition, as the concrete pump truck is limited by the bearing capacity of the car chassis, the cost increases greatly when the boom height exceeds 42m. Limited by the construction site space, it is rarely used.

3. Construction volume

The number of concrete pump trucks used can be calculated according to the amount of concrete pouring, the actual amount of conveyance per machine and the construction time. For those one-time concrete pouring a large amount of concrete pump construction projects, there must be a certain amount of reserve. In addition, the concrete mixing station with an annual output of 10 -- 150,000 m3 needs to be equipped with 2 -- 3 concrete pump trucks.

4. Product configuration

People should insist on high quality when choosing concrete pump. If high value concrete pump truck is selected, the standard of its products must be improved. The quality of the main components of the product, from internal quality to external quality, should be adapted to the high value of the whole vehicle.

5. Power system

The concrete pump truck adopts full hydraulic technology. So it is necessary to consider whether the hydraulic technology used is advanced or not. Therefore, in addition to the performance and quality of the engine, the performance, bearing capacity and quality of the automobile chassis should also be considered.

6. Operating system

The operation control system on the concrete pump truck is provided with manual, wired and wireless control modes, which are convenient and flexible. Wireless remote control can be operated remotely. Once the circuit fails, manual operation mode can be adopted.

7. After-sales service

As a special vehicle, the concrete pump truck should be required for its safety, mechanical performance, after-sale service and parts supply. Otherwise, once the accident occurs, it not only affects the construction schedule, but also will produce the unimaginable consequence

With the combination of lighting, image and data processing, the industrial automated visual inspection systems can detect and monitor the production process and product appearance damage, which guarantees the high quality of products. Automated vision inspection equipment has been wildly use in many fields such as automotive, low voltage electrical, hardware, precision electronics and other fields. With many years of experience and abundant professional knowledge, Yiheda can design a complete visual inspection solution based on your needs.

Visual inspect system is produced in industrial automation. In modern industrial automation production, automated visual inspection equipment involves a wide range of inspection, measurement and part identification applications, such as auto parts size inspection and automatic assembly integrity inspection, electronic assembly line component automatic positioning, beverage bottle cap printing quality inspection, bar code and character recognition on the product packaging. The common feature of this type of application is continuous mass production and high requirements for appearance quality. Usually this kind of work with high repetitiveness and intelligence can only be done by manual inspection. We often see hundreds or even thousands of automated inspection machines workers to perform this process behind the modern assembly line of some factories. While the factory adds huge labor costs and management costs, it still cannot guarantee 100% inspection pass rate, and today's competition between enterprises has not allowed even 0.1% defects. In some cases, such as accurate and rapid measurement of small size, shape matching, color recognition, etc., it is impossible to continuously and stably perform with the human eye, and other physical quantity sensors are also difficult to use. At this time, people began to consider to combine computer's rapidity, reliability, and reproducibility of the results with the highly intelligent and abstract capabilities of human vision, thus there is gradually forming a new discipline - Visual inspection.

Visual inspection is the science and technology that have research on using computers to simulate the macroscopic visual functions of living things. In layman's terms, automated inspection equipment is to use machines instead of human eyes to make measurements and judgments. Firstly, the CCD camera is used to convert the ingested target into an image signal, which is transmitted to a dedicated image processing system, and converted into a digitized signal according to pixel distribution, brightness, color and the like; the image system performs various operations on these signals to extract the characteristics of the target, such as: area, length, quantity, position, etc.: Finally, it output results according to preset tolerances and other conditions, such as: size, angle, offset, number, pass/fail, presence/absence, etc. Visual inspection is characterized by automation, objectivity, and non-contact. Visual inspection emphasizes recognition and judgment, as well as reliability in an industrial field environment compared to image processing systems in general.

Visual inspection is a fairly new and rapidly developing field of research. From the 1950s, people began to study the statistical pattern recognition of two-dimensional images. In the 1960s, Roberts began research on 3D Visual inspection. In the middle of 1970s, MIT Artificial Intelligence Lab officially opened the "Visual inspection" course, and the research began to boom globally in the 1980s, Visual inspection has flourished, new concepts, new theories continue to emerge. Today, Visual inspection is still a very active area of research, with related disciplines include: image processing, computer graphics, pattern recognition, artificial intelligence, artificial neural networks, and more.

Magnetic flux leakage test refers to the formation of a leakage magnetic field on the surface of a test piece after it is magnetized due to defects on the surface or near-surface of the test piece. People can detect defects by detecting changes in the leakage magnetic field.

Briefly describe the magnetization of ferromagnetic components. In the magnetic non-destructive testing, magnetization is the first step to realize the detection, which determines whether the leakage magnetic field signal can be generated, and also affects the performance characteristics of the detection signal and the structural characteristics of the detection device.  Like magnetic particle inspection, magnetization is achieved by a magnetizer, including both a magnetic source and a magnetic circuit.  The magnetic source and the magnetic circuit change depending on the structure of the member to be tested.

What kind of magnetization can be divided into several categories? The magnetization methods can be generally divided into five categories, namely, alternating current magnetization mode, direct current magnetization mode, permanent magnet magnetization mode, composite magnetization mode, and integrated magnetization method.

What are the characteristics of magnetic flux leakage detection technology?

Because leakage magnetic field detection uses magnetic sensors to detect defects, compared with magnetic powder, penetration and other methods, the magnetic flux leakage equipment has the following advantages:

1. It is easy to realize automation. The computer judges the presence or absence of defects based on the detected signals.

2. The fundamentally high detection reliability can solve the influence of human factors in the magnetic powder and osmosis method, and has high detection reliability.  

3. can achieve preliminary quantification of defects.  In the range of wall thicknesses up to 30 mm, the inner and outer wall defects can be detected simultaneously.  In the detection of the pipeline, 5 high-efficiency, pollution-free automated inspection can achieve high detection efficiency.

Are you looking for a perfect eddy current testing machine manufacturer? BOKENA is one of the most professional eddy current test equipment suppliers in China. ECT Eddy current testing is a non-contact testing method, which mainly uses the electromagnetic field and electromagnetic induction between metals to detect. It is one of the NDT non-destructive testing methods in the industry.

The principle of eddy current testing is that the coil with alternating current is placed on the metal plate to be measured or outside the metal, tube to be measured (see figure). The alternating magnetic field will be generated inside and near the coil, which makes the induced alternating current in the sample appear to be eddy, which is called eddy current. Under certain conditions, the current through the coil is invariable. If the coil is close to the workpiece under test, like a ship in the water, the eddy current will be induced in the workpiece. Under the influence of the eddy current, the coil current will change. Because the size of the eddy current varies with the defect in the workpiece, the change of coil current can reflect the defect in the workpiece.

MFI Magnetic flux leakage test refers to the formation of a leakage magnetic field on the surface of a test piece after it is magnetized due to defects on the surface or near-surface of the test piece. People can detect defects by detecting changes in the leakage magnetic field.

Briefly describe the limitations of the magnetic flux leakage detection method.

The limitations of the magnetic testing equipment are as follows:

1. It is only applicable to ferromagnetic materials.  
2. Detection sensitivity is low.
3. The quantification of defects is rough.  
4. Due to the shape of the workpiece to be inspected, the leakage magnetic field method is not suitable for detecting test pieces with complicated shapes because the sensor detects the leakage flux.  
5. Magnetic flux leakage is not suitable for cracking very narrow cracks, especially closed cracks. It was found in the experiment that cracks with very narrow cracks, magnetic particle flaw detection and magnetic flux leakage inspection failed to produce an indication of injury and injury.

Briefly describe the application range of magnetic flux leakage detection technology.

1. The application of magnetic flux leakage detection in the steel industry: in steel mills, it is mainly used for inspection of steel structural parts, billets, round bars, bars, steel pipes, welds and steel cables. Make sure the finished product is in good condition. On many occasions, users will not receive steel products that have not been inspected by steel mills and third parties.  Users often use non destructivetesting equipment before manufacturing, which ensures the manufacturer's technical requirements for the product. Such inspections are often carried out by an independent inspection company or the user's quality assurance department.  
2. The application of magnetic flux leakage detection in the petrochemical industry: the installation of oil and gas pipelines (including buried pipelines), storage tank floor or the recovery of oilfield steel pipes.  
3. Other applications: regular in-service inspection of used steel cables, wire ropes, and chains.

BKN's benchtop magnetic flux leakage testing equipment are capable of detecting workpieces efficiently and accurately.

The system is suitable for the automatic detection of various internal and external defects of steel pipes. The principle of ultrasonic flaw detection is that after the ultrasonic wave is coupled into the steel pipe through water, the incident propagation will cause ultrasonic reflection when there is a defect in the pipe. The ultrasonic instrument will alarm the ultrasonic reflected signal after realizing the signal to realize the automatic detection of the defect; Transmission ultrasonic pipe testing equipment is currently the advanced detection equipment in China.

Bulk Density Tester

Magnetic flux leakage test refers to the formation of a leakage magnetic field on the surface of a test piece after it is magnetized due to defects on the surface or near-surface of the test piece. People can detect defects by detecting changes in the leakage magnetic field.

Briefly describe the magnetization of ferromagnetic components. In the magnetic non-destructive testing, magnetization is the first step to realize the detection, which determines whether the leakage magnetic field signal can be generated, and also affects the performance characteristics of the detection signal and the structural characteristics of the ndt machine. Like magnetic particle inspection, magnetization is achieved by a magnetizer, including both a magnetic source and a magnetic circuit. The magnetic source and the magnetic circuit change depending on the structure of the member to be tested.

What kind of magnetization can be divided into several categories? The magnetization methods can be generally divided into five categories, namely, alternating current magnetization mode, direct current magnetization mode, permanent magnet magnetization mode, composite magnetization mode, and integrated magnetization method.

What are the characteristics of magnetic flux leakage detection technology?

Because leakage magnetic field detection uses magnetic sensors to detect defects, compared with magnetic powder, penetration and other methods, it has the following advantages:

1. It is easy to realize automation. The computer judges the presence or absence of defects based on the detected signals.
2. The fundamentally high detection reliability can solve the influence of human factors in the magnetic powder and osmosis method, and has high detection reliability.
3. can achieve preliminary quantification of defects.  In the range of wall thicknesses up to 30 mm, the inner and outer wall defects can be detected simultaneously.  In the detection of the pipeline, 5 high-efficiency, pollution-free automated inspection can achieve high detection efficiency.

How electronic fence works

After the pulse generator (main unit) is energized, the transmitting port sends a pulse voltage to the front fence. The time interval is about 1.5 seconds, and the pulse stays on the fence for about 0.1 second. After the loop is formed on the front fence, the pulse is returned to the host for reception. Port, this port receives the feedback pulse signal; the host also detects the resistance between the two transmitters. If the front fence is broken and the circuit is broken or shorted, the receiving port of the pulse host can not receive the pulse signal or the resistance between the two transmitters is too small, the host will issue an alarm.

Fence alarm

Through the working principle of the electronic fence, no matter what voltage working state the pulse host is in, when the fence is damaged, the receiving port can not receive the pulse signal, the pulse host will alarm; similarly, when the two electronic cables are short-circuited When the resistance is very small, the pulse master will also alarm.
