Simple and easy to learn without maintenance: simple and easy to learn operation, low failure rate, basically no maintenance, closed space, low noise
High sandblasting efficiency: adopt press in sandblasting and equipped with compressed air source, the jet is stable, the closed plug is automatically blocked, and the sandblasting speed is fast
Precise control: manual or arsine pedal control switch can also be added with instantaneous control flow to stop sandblasting instantly
Wide range of application: it can be applied to sand of various materials and particle sizes and diameters
Safety: the pressurized tank has stable performance and high safety
The open sandblasting machine adopts press in sandblasting, and uses compressed air to pressurize the abrasive in the high-pressure tank, so that the abrasive flowing from the bottom of the high-pressure tank has the same pressure when it meets with the compressed air. Then the abrasive is mixed with compressed air and sprayed to the surface of the workpiece at high speed, so that the workpiece can achieve the purpose of sand blasting. In the working state, compressed air and sand are mixed and sprayed at the same time, so that the compressed air can be fully used. The air flow and sand flow are easy to adjust, and the ideal mixing ratio can be obtained. The energy and sand consumption are less, and the cleaning efficiency is high. It is suitable for the surface cleaning treatment of workpieces and similar parts provided by customers.
 | Configure 1 set of outer diameter φ 400mm, the effective volume of the tank is about 0.1 cubic meters, and the pneumatic control sandblasting machine is adopted. The pressure tank container of sandblasting machine is welded from boiler steel plate. All welds shall be subject to magnetic particle inspection and pressure test. The technical indexes fully meet the national safety technical index standards. The tank surface shall be painted (two layers of antirust paint and one layer of finish paint). The middle of the tank is equipped with an access hole to facilitate workers' assembly, disassembly and maintenance. The sand volume control valve adopts manual control, and the operator can adjust the air flow and sand flow according to the sand blasting requirements, so that the air flow and sand flow can get an ideal mixing ratio, and improve the efficiency of sand blasting. |

The main function of the sand valve is to control the opening and closing of the sand material, and adjust the sand blasting volume infinitely. It is installed at the bottom of the sand blasting host. The nine way adopts the imported clemco pneumatic control sand blasting valve, and the air clamp control mode, which has the advantages of high accuracy, large sand production, uniform sand production, convenient adjustment, safety and reliability, long service life (more than 3000 hours). Customers can also choose Thomson or domestic sand valves | The function of the rotary feeding valve is to control the opening and closing of the sand and adjust the sand blasting flow. It is installed on the top of the sand blasting host. It has a jacket structure. The driving part is a diaphragm cylinder, which has stable and reliable performance, almost no maintenance, large sand output and sensitive control. In addition, the material level sensor is installed on the sand blasting tank, which is conducive to the personnel to identify the sand adding amount of the sand blasting tank. When the sand reaches the set value, the rotary feeding valve automatically closes, which is simple and efficient. | The main function of the stop valve is to close the stop valve when the rotary charging valve is replaced or repaired, so that it is not necessary to discharge all the sand when replacing and repairing the rotary charging valve, which saves time and effort. | The independently developed and designed high-speed sandblasting gun, venturi shaped nozzle, is made of boron carbide, with a long service life of 800-1000 hours; Compared with the ordinary spray gun, the venturi spray gun has faster sand blasting speed, 50% higher working efficiency, and the working efficiency can reach 35m2/h, with small recoil force, high efficiency and labor saving. | Wear resistant special sand blasting pipe is adopted, and the model is φ 32*51*20m, one end of the sand blasting pipe is equipped with a flexible and convenient quick connector, and the other end is equipped with a nozzle connector . |
