What is the principle of sand blasting machine?

The sand blasting machine uses the grinding fluid as the feeding power of the grinding fluid, and sends the evenly stirred grinding fluid (a mixture of abrasive and water) to the spray gun through the grinding fluid pump. As the acceleration power of grinding fluid, compressed air enters the spray gun through the air pipe. In the spray gun, the compressed air accelerates the grinding fluid entering the spray gun, and is ejected through the nozzle and sprayed onto the surface to be processed to achieve the desired processing purpose. In the liquid sandblasting machine, the grinding liquid pump is the feeding power, and the compressed air is the acceleration power.

What is the workflow of sand blasting machine?

Due to the impact and cutting effect of abrasives on the surface of the workpiece, the surface of the workpiece can obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece are improved, thus improving the fatigue resistance of the workpiece and increasing its adhesion between the coating and the coating prolongs the durability of the coating film. The sand blasting machine is also beneficial to the leveling and decoration of the paint, removing impurities, variegation and oxide layer on the surface, and at the same time roughening the surface of the medium, eliminating the residual stress of the workpiece and improving the surface hardness of the substrate.

What are the advantages of sand blasting machine?

1. The number and arrangement of shot blasting are calculated by computer shot blasting simulation. The 8 impellers are located up, down, left and right, respectively, to ensure that the shot blasting projectile covers most of the steel surface, including the ends. It ensures that the effect of shot blasting is comprehensive and effective.

2. The system of the sand blasting machine is a centrifugal hedging type shot blasting machine, which has the advantages of large blasting amount and fast ejection speed. The quantity and momentum of projectiles ejected to the surface of the workpiece in unit time are greatly improved. Therefore, the shot blasting time can be shortened, the efficiency can be improved, and a satisfactory cleaning quality can be achieved.

3. The dust removal system adopts filter type backwashing. The dust collector adopts a folded dust filter cartridge, which increases the dust removal area. The filter cartridge adopts nanofiber technology; the dust removal efficiency is over 99.99%, especially for dust particles with a diameter of 0.5μm. After high-efficiency filtration, the air is clean and can be recycled or discharged indoors. The pulse controller can adjust the frequency, speed and intensity of dust removal. Compared with the traditional domestic bag-type single-stage dust removal system, it has the advantages of high dust removal efficiency, small running resistance, small size, light weight and convenient replacement. Emissions comply with national emission standards.

What is the application of orbital welding machines?

At present, the development of railways is mainly towards high-speed passenger cars, subway passenger cars, light rail cars, high-speed heavy trucks, etc. To meet these requirements, it is necessary to adjust the weight of the trains. Nowadays, it is common practice to use aluminum alloy materials in the manufacturing process of passenger cars. Because aluminum alloy materials have the characteristics of light weight, corrosion resistance, smooth appearance, complex curved surfaces and high specific strength, they can effectively reduce the resistance and quality of passenger cars. Increased overload. In order to effectively improve the processing efficiency of aluminum alloy materials, it is necessary to change the traditional processing method and use the welding technology of orbital welding machine for processing and manufacturing.

How is the orbital welding machine used?

(1) Welded parts preparation: Given the high hardness of rail steel, it is difficult to process the groove on site. Therefore, the orbital welding machine adopts the docking method and uses the existing end surface of the rail as the working surface. If the end face is heavily corroded, the angle grinder must be used to polish the surface bare.

(2) Determination of the impact gap: Given the height of the rail itself, the gap must not be too small, otherwise the welding wire for welding work cannot penetrate it, so it is necessary to reserve enough gap.

(3) Welding preheating: In the preheating process of orbital welding machine, a gas welding torch is used for preheating, and an infrared temperature measuring gun is used to ensure that the preheating reaches the specified temperature.

(4) Shock surface process: The entire welding process adopts the multi-layer multi-pass welding process. Although this process is relatively inefficient, it can ensure the weld strength and temperature between the layers.

(5) Heat treatment after welding: The heating process of the orbital welding machine uses a gas welding torch. After heating to the specified temperature, asbestos felt is used for heat preservation to prevent the appearance of cracks after welding.

(6) Grinding the workpiece after welding: The orbital welding machine keeps the weld seam and the base metal of the rail smooth.

What are the features of the orbital welding machine?

The biggest feature of orbital welding machine is small-scale local heating, high heating efficiency, easy operation, which is very suitable for fast heating and cooling of high manganese steel welding, and also suitable for welding repairs of local defects on rails. It is currently the most widely used method for welding rails and track grooves. Methods. However, it must be noted that the orbital welding machine for rail welding must be properly preheated. Due to local heating and rapid cooling of the rail, slightly abnormal brittle structures such as martensite and bainite can be generated, which increases the brittleness of the rail. Preheating prevents abnormal tissue formation.

In contrast to the current round welding machines on the market, the tank welding machine of the MSHW series offered by WINCOO Engineering is equipped with a dual drive system as standard. This self-propelled submerged welding system can reduce tank welding time on site by 40%. Welding errors are greatly reduced, saving tank installation costs. The circumferential welding machine is suitable for top-down or bottom-up constructions of single- or double-wall storage tanks for internal and external welding. There are four standard units, but our design allows us to offer custom mounting units for non-standard applications.

What are the working characteristics of the tank welding machine?

The tank welding machine belongs to fusion welding, in which a laser beam is used as energy to act on welds.

The laser beam of the tank welding machine can be guided through a flat optical element (such as a mirror), and then the beam is projected onto the weld by a reflective focusing element or mirror.

Tank welding machine is a non-contact welding process that does not need to be pressurized during operation, but an inert gas is required to prevent oxidation of the melting pool, and occasionally filler metal is used.

The tank welding machine can be combined with MIG welding to form laser MIG composite welding to achieve large-impact welding, and the heat supply is greatly reduced compared to MIG welding.

What is the workflow of the tank welding machine?

The circumferential welding equipment is a tank welding machine. The most important welding parameters in circular welding include welding current, welding torch speed, inert gas flow, etc. At the same time, the clearance fit of welded joints also plays a decisive role. Under the existing conditions, pipe ends are machined before welding lathes and repaired by fitters. In this case, the dimensional accuracy of the short ends is difficult to meet the requirements of the drawings, resulting in uneven fit gaps between the pipe ends and pipe connections; In addition, if the pipeline is displaced during staple welding, this will cause uneven spacing of the fitting surface, so that the surface of the weld is pressed in after circumferential welding. During the welding process of tank welding machine, the inside of the pipe is protected by argon gas. If there is no argon gas protection in the line, the back of the weld will be poorly formed and at the same time oxidation will occur.

Based on the availability of the customer's plant/site, WINCOO ENGINEERING CO., LTD is able to study/design and present coordinated configurations on project plan, quality, cost and productivity to ensure production pace meets project requirements.
