Is using compressed air as the power, to form a high-speed jet beam of the spraying material (copper ore, quartz sand, emery, iron sand, sea sand) high-speed jet to be handles the workpiece surface, make the appearance on the surface of the workpiece surface appearance or shape change, due to the abrasive impact to the surface and the cutting effect, make the surface of the workpiece for cleanliness and different roughness, the workpiece can improve the mechanical properties of the surface, thus improve the fatigue resistance of the workpiece, increase the adhesion between the coating and its, extend the durability of the coating, but also to the flow of paint and decoration.
Preparation before starting up
1. Check whether all wiring points are firm
2, check whether the air compressor oil is enough, should be between the oil level needle
3. Check whether the cooling water is sufficient and the cooling water pipeline is unblocked
Boot sequence:
1. Turn on the pump switch to ensure that there is water flowing out of the outlet.
2. Close the air inlet valve
3, start the air compressor, no-load operation for 2~3 minutes, check whether there is any abnormal noise, motor running direction is wrong, if there is, immediately stop.
4. After 2~3 minutes of no-load operation, fully open the air inlet valve at a uniform speed to make the machine run under load.
Shutdown sequence:
1. Close the air inlet valve.
2. Open all exhaust valves (exhaust valve under the storage tank, exhaust valve on the sand tank), discharge pipeline and pressure in the storage tank.
3. Press the stop button to stop the air compressor.
