Electrical Control System: Remote on/off, automatic feeding leh pressure regulation neih theihna turin button, remote control, sensor, etc. te a inzawm khawm a.
3. Auxiliary system 1.1.
Sandblasting hose: Hose bik, pressure resistance sang leh wear resistance nei, mixing chamber leh spray gun inzawmkhawm.
Spray Gun: Operator-in a vawn emaw, mechanical hand-a clamp emaw, a chhunga awm, abrasive jet chu a ti chak lehzual a, a chhungah ceramic emaw tungsten carbide nozzle emaw hmanga siam a ni.
Abrasive recovery and separation system (closed shot blasting room-ah) : Ground grilles, screw conveyor, elevator, cyclone separator leh vibrating screens, etc. te a awm a, chungte chu recover, clean reusable abrasives leh leivut leh bawlhhlawh paih chhuahna atan hman a ni.
Dust Removal System: Large-scale cartridge dust collectors hmangin shot blasting laiin leivut lo chhuak chu an khawl khawm a, hnathawhna hmun thianghlim taka vawn leh boruak humhalhna mamawh phuhruk nan an hmang thin.
II a ni. Shot blasting tank hman dan tur .
Shot peening technology hian high-speed abrasive flow hmangin workpiece chunglam a nghawng a, chu chuan industrial purpose hrang hrang a thlen thei a ni. A hmanna ber field-ah chuan:
Surface tihchakna/shot peening tihchakna .
Hei hi hmanna hlu ber a ni. Abrasives te tak te chhiar sen lohin a nghawng dan hian, residual compressive stress layer chu metal parts (gears, springs, aero engine blades, connecting rods, etc. ang chi) chunglamah a rawn lut a, chu chuan fatigue strength, stress corrosion resistance leh service life te chu nasa takin a tichak a ni. Hei hi aircraft siamna, automotive engine siamna, leh high-load transmission components siamna kawnga thil pawimawh tak a ni.
