Construction site construction, often see the wear-resistant sandblasting tube figure. In the wear-resistant sandblasting pipe construction process, the construction before the need to adjust the construction process specifically how to work?
First, the wear-resistant sandblasting pipe before the adjustment:
1, the compressed air to adjust the compressed air pressure of 0.4-0.6MPa, roller roughness value is large, coarse sand, the compressed air pressure increase, and vice versa down.
2, wear-resistant sandblasting tube nozzle adjustment Two nozzle should be transferred to the vertical roller surface, the nozzle to the roller surface distance of 60-100mm.
3, the adjustment of the nozzle stroke Adjust the position of the two stroke stopper, you can according to the needs of the sandblasting length of the nozzle to change the movement of the trip.
4, wear-resistant sandblasting tube nozzle speed adjustment drive the nozzle movement of the motor frequency control, the inverter output frequency adjusted to 6.5-8.5Hz, the motor speed is about 0.6r / min, the nozzle speed of about 2.67mm / so5, roller speed adjustment drive roller rotation of the motor is also frequency control, for the diameter of 250mm roller, the inverter output frequency adjusted to 22-30Hz, roller speed of 11-14r / rain.
6, adjust the sand into the mouth of the hopper in the bottom of the two into the sand mouth, in the sand into the mouth can be pre-conditioned air intake of the size of the population to control the amount of air intake, usually transferred to the opening half of the work to be adjusted The
7, sand requirements of the sand material is generally fused corundum, particle size of 0.8-1.2mm, storage hopper to be maintained 100-150kg sand material; roll roughness value is large, the size of a large value, and vice versa.
