Common sense for correct operation of pressure blasting machine :
Pressure sand blasting machine is the most efficient sand blasting equipment for modern surface treatment. At present, various industries have a low cost and high cost performance. For various casting internal and external surface workpiece cleaning equipment, pressure blasting machines are mainly used for workpiece surface requirements. Higher products, in outdoor protection engineering, easy to corrode materials or machined workpieces, the surface to remove marks, rust, rusted metal surface to remove oxide scale treatment.
In daily operation, the operating rules of the pressure blasting machine are directly related to the matters of safety production. The safety operating rules are as follows:
1. The particle size of the blasting abrasive should be in accordance with the surface roughness requirements of the workpiece. Generally, the number of meshes used for sand blasting is about 100 meshes. The surface requirements of the workpiece should be determined according to customer requirements. All abrasives should be kept dry.
2. The storage tank, air inlet valve, air inlet pressure gauge, safety valve and abrasive valve of the pressure type sand blasting machine should be checked regularly. The air storage tank should be filled with sedimentation water once a day, and the filter in the sand tank should be checked every three months, and the ventilation ducts of the pressure sand blasting machine and the doors and windows of the sand blasting room should be regularly checked for integrity.
3. When working in the blasting room, all unrelated personnel are prohibited from entering the blasting room. After the blasting is completed, do not blow the dust on the body with the blasting compressed air. Keep the blasting room clean after each blasting work.
Fourth, the pressure type sand blasting machine must be opened before the work of ventilation and dust removal equipment, filter-type ventilation and dust removal, equipment failure, it is strictly prohibited to work in the blasting room, let alone naked body in the blasting room to operate the pressure blasting machine, open the pressure The compressed air of the inlet valve of the sand blasting machine should be opened slowly.
