Introduction Of Working Method Of Tongda Analysis Machine

Posted by tongdaedith on Apr 13, 2020 in News

With the acceleration of China’s economic process, China’s industrial development model and level are also constantly improving and upgrading.  Many industrial appliances have undergone updated changes, such as flaw detectors, which have diversified due to the diversity of working methods.  The main application of X-ray detection is to detect macroscopic geometric defects (flaw detection) in side samples.  According to different characteristics such as radiation type, recorded equipment, process and technical characteristics, etc.  The radiographic testing of Tongda analysis equipment can be divided into many different methods.  Radiography is a nondestructive testing method, which uses X-rays or gamma rays to penetrate the test piece and uses film as information recording equipment.

This method is a basic and widely used ray detection method.  Therefore, if there is no adjustment device, Tongda analyzer is very inconvenient to use.  The power supply of portable X-ray machine is 220V and 50Hz single-phase AC.  After entering the control box and passing through the power switch, the power supply is divided into two paths, one of which enters the main circuit and the other feeds into the weak current control part.  The main circuit is mainly composed of a voltage regulating and rectifying unit, a liquid crystal filtering unit and an inverter unit, also known as a chopping unit. The output pulse signal is provided to the primary of a high-voltage transformer (commonly known as a high-voltage package).  The control units produced by different manufacturers are different, but their functions are basically the same, including generating trigger control signals, exposure time, milliamp protection, overvoltage protection, overtemperature protection, etc.  Some devices are controlled by single-chip microcomputer or microcomputer to realize the functions of automatic trainer, voice prompt, fault code display, exposure parameter setting, storage, memory, etc.  In general, the adjusting device should be able to adjust the Tongda analyzer with six degrees of freedom to adjust the height and opening.

When these three functions can be adjusted, Tongda analysis machine can basically be freely expanded and contracted, making it more flexible to use.  As for the working method of this tool, it is also based on a series of researches and related achievements of China’s physical and chemical industries.  It is divided into several different types and applied in different fields.

Sensitivity Of Tongda Analysis Equipment

Posted by tongdaedith on Mär 30, 2020 in News

Explanation of Sensitivity in Tongda analysis machine
1. When using Tongda analysis equipment to magnetize some complex workpieces, the magnitude of magnetizing current is difficult to estimate due to the uneven distribution of magnetic field intensity on the surface of the workpieces.
It is often difficult to achieve the ideal magnetization effect by only relying on the usual detection experience to select the magnetization current in Tongda analysis equipment.
Therefore, we can use sensitivity test pieces to select the best magnetization specification in the examination of complex workpieces by Tongda analysis equipment.
2. The sensitivity test piece can be used to check:
The comprehensive performance of flaw detection equipment such as Tongda analysis equipment, magnetic powder and magnetic suspension is used to check the distribution law of magnetic field at each point on the surface of the workpiece to be inspected.
The main methods of using sensitivity test pieces in Tongda analysis equipment are:
(1) firstly, using adhesive tape paper to tightly adhere the slotted side of a type a standard test piece to the clean surface of a detected workpiece;
2) While magnetizing the workpiece and the test piece with Tongda analysis equipment, spraying magnetic suspension on the test piece and observing the magnetic marks on the test piece;
3. Under the condition of using sensitivity test piece, if the magnetization current of Tongda analysis equipment is appropriate;
Then magnetic marks with grooves will appear clearly on the uncut groove surface of the test piece so as to achieve the detection effect.

Function Of Tongda Analysis Equipment

Posted by tongdaedith on Mär 9, 2020 in News

The detection technology of Tongda analysis machine is to predict the development of defects based on the detected defects, so it is required to detect the types, shapes, sizes, positions and directions of defects as accurately as possible so as to carry out life assessment and quality assessment.  Specifically, the role of NDT is as follows:

1. Ensure the quality of workpieces or equipment and ensure the safe operation of equipment.  Non-destructive testing is used to ensure the quality of the product, so that part or the whole of the product will not be damaged within the expected service life under the specified service conditions, thus preventing equipment and personnel accidents.

2. Improve the manufacturing process.  We can first make samples or test products according to a predetermined manufacturing process, carry out nondestructive testing on them, and use nondestructive testing to observe whether the process for manufacturing samples is suitable, thus improving the process while observing until the manufacturing process meeting the quality requirements is determined.

3. Reduce the manufacturing cost.  Testing by Tongda analysis equipment can reduce the manufacturing cost.  Proper and correct nondestructive testing in the manufacturing process of products can prevent work pieces from being discarded after finishing processing, thus reducing the manufacturing cost.

Introduction To The Principle Of China Benchtop Xrd

Posted by tongdaedith on Jan 13, 2020 in News

When an electric current is applied to the filament of an X-ray tube to heat it to an incandescent state, free electrons are emitted from the surface of the filament. At the same time, the high voltage of tens of thousands of volts is applied to the two ends of the X-ray tube (the anode is positive and the cathode is negative), which creates a strong electric field in the Tongda analysis machine tube, which will force the filament surface and its vicinity Of electrons fly out of the cathode and flow to the anode with great acceleration. When they collide with the anode target, the electrons are suddenly prevented from moving and lose their kinetic energy. About 99% of the kinetic energy is converted into thermal energy and about 1%. Into X-rays.
The free electrons flowing from the cathode filament to the anode form a beam of electrons called tube current. The amount of tube current depends on the number of free electrons emitted by the filament. The more electrons flowing from the cathode to the anode, the greater the tube current and the more electrons that hit the anode target per unit time. The more, the greater the intensity of the X-ray. The number of free electrons emitted by the filament depends on the temperature of the filament. The higher the temperature of the filament, the more electrons are emitted. The filament heating is supplied by the filament transformer. The voltage of the filament transformer is changed by controlling and adjusting, that is, the heating current of the filament is changed to achieve the purpose of regulating the tube current.
The X-ray intensity can be changed by adjusting the tube current. As long as the tube voltage is constant, the X-ray wavelength distribution remains constant regardless of the X-ray intensity.
The voltage applied across the anode and cathode of an X-ray tube is called the tube voltage, which can establish a strong electric field and control the kinetic energy of free electrons. The higher the tube voltage, the greater the kinetic energy of the electrons that hit the anode target, the higher the X-ray energy, the shorter its wavelength, and the stronger its ability to penetrate matter.
The tube voltage is supplied by a high-voltage transformer, usually the secondary winding of the high-voltage transformer is connected to the two poles of the X-ray tube; the primary winding is connected to the power source through a voltage regulator (or thyristor voltage regulation). By controlling and adjusting the primary voltage, the secondary voltage is changed to achieve the purpose of regulating the tube voltage.
With the increase of the tube voltage, the speed of electrons flowing to the anode increases, the number of electrons reaching the anode target surface per unit time increases, and the intensity of X-rays produced by China benchtop xrd also increases accordingly. However, the purpose of increasing the tube voltage is mainly to obtain high energy, that is, short-wavelength X-rays, to improve its ability to penetrate matter.
