Rust removal and sandblasting machines are the most widely used products in abrasive jets. Sandblasting machines are generally divided into two categories: dry sandblasting machines and liquid sandblasting machines. Dry sandblasting machines can be divided into suction type and press-in type. .

Suction dry sandblasting machine

1. General composition

A complete suction dry sandblasting machine generally consists of six systems, namely structural system, medium power system, pipeline system, dust removal system, control system and auxiliary system.

2. Working principle

The suction dry sandblasting machine is powered by compressed air, and the negative pressure formed in the spray gun by the high-speed movement of the airflow passes the abrasive through the sand pipe.

It is sucked into the spray gun and ejected through the nozzle, and sprayed to the processed surface to achieve the desired processing goal. In the suction dry sandblasting machine, compressed air is provided.

Press-in dry sandblasting machine

1. General composition

A complete press-in dry sandblasting machine work unit is generally composed of four systems, namely pressure tank, medium power system, pipeline system, and control system.

2. The working principle of the press-in dry sandblasting machine.

The press-in dry sandblasting machine is powered by compressed air, and the abrasive is passed through the sand valve through the working pressure established by the compressed air in the pressure tank.

Press into the sand pipe and shoot out through the nozzle, spray to the processed surface to achieve the desired processing goal. In the press-in dry sandblasting machine, compressed air is the supply.

Liquid sandblasting machine

Compared with dry sandblasting machine, the biggest feature of liquid sandblasting machine is that it can well control the dust pollution in the sandblasting process and improve the working environment of sandblasting operation.

1. General composition

A complete liquid sandblasting machine generally consists of five systems, namely structural system, medium power system, pipeline system, control system and auxiliary system.

2. Working principle

The liquid sandblasting machine uses the grinding liquid pump as the supply power of the grinding liquid, and the evenly stirred grinding liquid (mixed liquid of abrasive and water) is delivered into the spray gun through the grinding liquid pump. Compressed air as grinding fluid

The acceleration power enters the spray gun through the air pipe. In the spray gun, the compressed air accelerates the grinding liquid entering the spray gun, and it is ejected through the nozzle and sprayed to the processed surface to achieve the expected processing purpose. In the liquid sandblasting machine, the grinding fluid pump is the power supply, and the compressed air is the acceleration power.
