For pass-through projectiles, many may know it is used to clean up the stain of steel, but little is known about its operation. And here's what we're going to do。
The disposal of the projectile machine is carried out by means of high-speed rotating throws of grinding particles to the surface of the projectile, with several leaves inside the dump. At work, the grinding enters the centre of the throw through the feed mouth, and at the centre of the throw there is a distillation wheel that rotates with the throw, outside which is a directional condom, which delivers the grinding through the openings on the directional cord to the end of the blade near the dump centre. The kinetic grinding particles accelerate along the length of the blades until they reach the top of the blades at a very high rate of impact on the surface of the project。
The function of the distillation wheel is to properly “feed” the grinding material to the blades in accordance with certain requirements. Once the opening of the distillation wheel is severely worn, the grinding material will impact the end of the blade, causing an abnormal wear of the blades, and the spread of the grinding material will become irregular. Therefore, wear and tear on the distillation wheel is periodically checked in accordance with the requirements of the instructions and the severely worn rotor is replaced in a timely manner。
The directional opening position determines where the grinding material is fed to the leaf by the breaker. Depending on the shape of the opening to be applied, the dispersive shape of the grinder and the size of the heat zone. The so-called hot zone, even in an area where grinding is more concentrated, is due to its uneven distribution on leaves. The orientation package can be positioned in such a way as to provide appropriate mediation based on opening wear and tear and to ensure that work is done in good working condition。
The leaves in the dump are in direct contact with the grinding, and the quality is closely related to the performance of the tip。
The foliage resistance directly determines the lifetime of the foliage and the operating cost of the ostrich machine, so that the foliage is made of high-resistant material. In addition to being related to the material of the leaves, the foliage resistance is closely related to the condition of the projectile machine. For example, the presence of 1 per cent of the sand in the grinding material reduces the lifetime of the leaves by 80 per cent, and it is not too much to say that the life of the separation device determines the life of the projectile。
Fragmentation or fractures cause vibrations when the wheel rotates at high speed. Therefore, the soundness of the leaves is regularly checked and the faulty leaves are replaced in a timely manner. In order to ensure stability in the operation of the fallout, the change of leaves must be made in pairs, i. E., the change of leaves relative to the undesired leaves must take place at the same time in order to achieve a good working balance. If the problem of suspected leaves leads to anomalous work, all leaves need to be replaced。
The casting defects of the leaves will inevitably accelerate the wear of the leaves, which is even more serious when the iron ball is used for grinding. An analysis of the worn blades concluded that there were casting defects in the blades that would cause the grinding particles to bounce in the course of their movement, which in turn would swipe the blades, thereby increasing the wear of the blades. If sand is present in the grinding material, it increases the wear of the leaves。
Some companies have used tungsten and even boron to make leaves for throwing, with a significantly longer useful life. However, the fragility of these super-hard materials makes it impossible for these sandy blades to truly play their role in the field of projectiles。
