Pipe wallAutomatic sandblasting machineBefore the sandblasting operation, a series of inspections must be carried out on the mechanism in the sandblasting box. Specifically include: 1. Check the wear of the sandblasting pipe and the sandblasting rod. If they are damaged, they need to be disassembled and repaired immediately; 2. For the electromagnetic proximity switches of each limit in the sandblasting machine, for the damage, It should also be replaced immediately. 3. Start the air compressor unit to keep the air dry; 4. Turn off the switches in the power cabinet of the automatic sandblasting machine and the circuit breaker in the electric control cabinet.

The specific operation of the automatic sandblasting machine for the inner wall of the pipeline: 1. Press the "front door up" button on the operation cabinet panel, after the sandblasting box door is opened, press the "filling pipe" button in the cabinet panel to turn over The entrance board is raised, and then 6 pipes are placed horizontally on the entrance board. Press the "filling pipe" button, the flip-in plate will take the pipe to the corresponding working position, and it will rotate in the positive direction. Then press the "Front Door Down" switch to close the front door of the sandblasting box. 2. Sandblasting operations. By operating the&”gun forward&”and&”blasting start GG” buttons on the panel of the fully automatic sandblasting cabinet, the sandblasting flat car drives the spray gun to move forward slowly. When it starts to move forward or backward, it will blow air, and after a second it will blast sand. When the speed of the sandblasting flatbed vehicle reaches the 1 position of the speed limit sensor, the vehicle speed will be faster. When the speed limit sensor reaches the 2 position, it will change to the original speed again. When the sandblasting platform truck reaches the top of the front end of the pipe, it will automatically retreat, and will automatically stop after returning to the starting position.

In addition, when the abrasive in the sandblasting tank of the automatic sandblasting machine on the inner wall of the pipeline is at the lower limit, the system will issue a warning of insufficient raw materials. When the pressure of the sandblasting tank is greater than the atmospheric pressure, the pressure of the sandblasting tank appears on the display panel to be zero, and the indicator light of "Grit preparation GG" will be on. At this time, the staff should press the&on the cabinet panel "Add Abrasive GG" button and start adding abrasives until the indicator light of the&"Sandblasting machine full of GG" lights up, and then the automatic sandblasting machine can perform sandblasting again.
