The so-called high-pressure manual sandblasting machine mainly uses abrasives as its main working medium, and first compresses air as its power, and after the abrasives and compressed air are pressurized in the pressurized tank, they are then accelerated by the sand valve. After power, the abrasive is injected into the spray gun of the sandblasting machine and then sprayed onto the surface of the workpiece to be processed to complete the expected purpose.

We can conduct an in-depth analysis and understanding of the working principle of the high-pressure manual sandblasting machine from the following three aspects:

1. Working principle of air circuit

When the sand blasting machine is working, we can divide the compressed air entering the sand blasting machine into two paths: one is to enter the pressurized tank, and the other is to enter the air gun. The main job of the air source entering the pressurized tank is to complete the sandblasting process of the sandblasting machine; while the air source entering the air gun is used to clean the surface of the workpiece and some dust accumulated in the sandblasting cabin , make sure it is clean.

2. Working principle of sand road

Add an appropriate amount of 15~25kg of abrasives to the pressurized tank before starting. When the sandblasting machine is working, the top valve of the pressurized tank will float. At this time, it is necessary to close the sanding port. At this time, the abrasive After mixing and pressurizing in the pressurized tank, the sand valve is then lowered. At this time, after the acceleration of the compressed air, the treated abrasive will be ejected out of the spray gun, and then it can be properly processed on the workpiece.

3. Working principle of dust collector

Connect the dust collector and the separator with a suction pipe. After starting, a negative pressure will be formed in the cabin of the sandblasting machine, and then after a series of work processes, a continuous gas will be formed in the sandblasting machine Circulating flow in the cabin; then under the action of the airflow, after a series of operations, the dust in the cabin can be finally cleaned.
