This machine uses abrasive as the working medium and compressed air as the power. After the abrasive and compressed air are pressurized in the pressurized tank, they are accelerated by the sand valve, and then the abrasive is injected into the spray gun and sprayed onto the workpiece surface to achieve the expectations. For sandblasting purposes. |
1. The working principle of the gas circuit The compressed air source entering the dry blasting machine is divided into two paths: one goes to the pressurized tank, which is used to pressurize the abrasive to complete the sand blasting process. The compressed air is oiled through the filter. Water filtration, the pressure of the compressed air entering the spray gun can be adjusted through the pressure reducing valve, and the opening and closing of the compressed air is controlled by the solenoid valve; all the way into the air gun is used to clean the surface of the workpiece and the sand slag (dust deposit) in the blasting chamber.
2. Working principle of sand road The abrasive is placed in the pressure tank in advance (open the cabin door, and 15 ~ 25kg of abrasive is added to the cabin). When the pneumatic solenoid valve is activated, the top valve of the pressure tank floats and closes the sand inlet. The abrasive is mixed and pressurized in the pressure tank, and then pressed to the lower sand regulating valve. After being accelerated by compressed air at the sand regulating valve, the spray gun is ejected, and the workpiece can be sandblasted.
3. Working principle of the dust collector The dust collector is connected to the separator with a dust suction pipe. When the dust removal fan is started, a negative pressure is formed in the sand blasting machine cabin, and the external air is replenished to the blasting cabin through the air inlet, and then enters through the sand return pipe. After the separator, it is sucked into the dust collector by the dust collector fan, so that a continuous gas circulation flow is formed. Under the action of the flowing gas, the dust floating in the blast chamber enters the dust removal unit along the connecting pipeline along with the air flow, and is filtered. After the bag is filtered, it falls into the ash collecting hopper, and the filtered clean air is discharged through the exhaust port of the dust removal fan; the dust can be collected by opening the cover at the bottom of the dust removal box.
