In front of us, we introduced the structure and working principle of the pipe inner wall sandblasting machine system, and then introduce the operation and use of the pipe inner wall sandblasting machine

The operation of the sandblasting machine for the inner wall of the pipe is divided into four steps. In the sandblasting operation, first of all, a series of inspections should be carried out on the mechanism in the sandblasting box. If some damage is found, including the wear of the sandblasting pipe and the sandblasting rod, it should be replaced and overhauled immediately, and the sandblasting machine cannot be put into use at this time. The operator should also deal with the electromagnetic proximity switch of each limit, and replace it immediately for the damaged condition. The compressor unit for the air is activated so that the air remains dry. Close the switches in the power cabinet and the circuit breaker in the electric control cabinet. For some power switches on the operating cabinet panel, adjust them to the corresponding positions. When the pressure of compressed air is about 0.6MPa, the ball valve and gate valve of each gas path are opened. The second is to carry out specific operations. Press the "front door up" button on the operating cabinet panel, and the sandblasting box door will be opened, then the "filling pipe" on the operating cabinet panel will be opened to raise the turning plate, and then the civilian pipeline will be pushed horizontally into the turning plate in the spray box. Close "Fill Tube". After putting down the flip-in plate, the pipe will fall on the tube wheel in the corresponding working position and rotate in the positive direction. After that, press the "front door down" switch to close the front door of the sandblasting box. Through the buttons of "spray gun forward" and "sand blasting start" on the operation cabinet panel, the sand blasting flatbed truck drives the spray gun forward slowly. When it starts to move forward or backward, it will blow air, and sand blasting will take another second. When the speed of the sandblasted flatbed truck has reached 1 of the speed limit sensor, the speed will be faster. When it reaches 2 points of the speed limit sensor, it will become the original speed again. When the sandblasted flatbed truck reaches the forefront of sandblasting, it will automatically retreat. The retreating and the workpiece rotation are then automatically stopped until the retreating to the starting stop position. For the operation of adding abrasives, when the abrasives in the blasting tank are in the lower limit state, the system will predict the shortage of materials and play a reminder role. When the pressure in the sand tank is greater than atmospheric pressure, the "sand tank pressure is zero" indicator light will turn on. The indicator light of "sand preparation" will be on, and then sand addition will be delayed. Open "Add Abrasive" on the operation cabinet panel and start adding abrasives. The pneumatic feeding valve will automatically feed the material until the indicator light of "sandblasting machine full" is on. After the sandblasting operation. The last step is to stop the machine, return the buttons to the original position in a certain order, and then close the air compressor unit to exhaust the compressed air in the air tank.

The implementation of sandblasting operation mainly compressed air, the air into power, the formation of high-speed jet beam, and then the abrasive high-speed jet to the need to deal with the site. Make the treatment of parts change, sand for the surface of the workpiece has a certain impact and cutting effect, can make the surface of the workpiece to achieve the purpose of cleaning. The performance will also change, improve the fatigue resistance of the workpiece, so that the adhesion between the coating and the coating becomes larger, and the durability of the coating film becomes higher.

CNC sandblasting machine processing large metal workpieces, the effect is better!

Warmly Congratulate Baitong on Setting up CNC Sandblasting Machine R & D Center in Beijing

In 2010, Baitong Machinery joined hands with Tan Lao, the earliest domestic research and development of sandblasting equipment, and formally established a sandblasting research and development center in Beijing. At present, Tan is one of the first founders to introduce sandblasting technology in China. He has won many expert awards and hundreds of patents at home and abroad. He has very high authority in the field of sandblasting. This cooperation has revolutionized Baitong Machinery in sandblasting technology. In January 2011, Baitong Machinery broke through the technical problem of numerical control sandblasting. Baitong Machinery has now become the first enterprise to manufacture numerical control sandblasting system. In February 2011, Baitong Machinery carried out technical research and development and transformation of sandblasting manipulator. It can be imagined that the first sandblasting manipulator manufacturer in the near future is Baitong Machinery
