China's sandblasting gun
industry has suddenly changed its methods, and the specific force is still frequent. It is of great significance to study the safety instrumentation skills, which is very convenient for repair and maintenance. The operation of the sand blasting gun is simple, the seal ring is generally effective, and the assembly and replacement are more convenient than force. Closely reliable. At present, the sealing material of ball valves is widely used in plastics, and has good sealing performance. It has also been widely used in vacuum systems.
At the same time, it also contains the research and development of sandblasting gun product evaluation skills. Product Note: It ’s a social rhetoric. With the collapse of the bridge, the phone line was cut off. The scientific team ’s opinion is this. The level of functional skills has reached the level of the advanced in the country. Compared with American standards, it is easy to operate and open and close. Agile, only need to reverse 90 from fully open to fully closed. T-type filter for long-distance control.
For sandblasting, it is more convenient to use a hand to hold the workpiece under the jet stream. For heavy workpieces placed on the workbench, the sandblasting gun is
controlled on the workpiece. When sandblasting, it is difficult to see the processed part. Therefore, it is necessary to control a reasonable spray diameter. During the process, do not hold the spray gun statically or too close. If the applied spray force is too large, use coarse abrasives. At this time, the jet surface can easily damage the surface of the workpiece.
Low pressure produces a small jet impact force and good polishing effect, high pressure produces a large jet stream impact force, and the sandblasting equipment has a high sandblasting efficiency, which reduces the polishing effect. If the compressed air pressure is too high, it may interfere with the abrasive flow and reduce the processing efficiency. The pressure of the high-speed compressed air by a manual pressure regulating valve should be adjusted when the blast gun is
