The control method of Dongguan Meijun rust blasting machine:

By configuration:

1) Basic steel structure descaling sandblasting machine: pure manual type, basically a pressure-maintaining assembly.

Inlet valve (ball valve control switch) + sand adjusting valve (ball valve control switch). Without electric control and pneumatic control system, 2 people are required to operate at the same time, one person takes a gun to blast the workpiece, and the other person controls the machine switch.

2) Derusting sandblasting machine for pressure-maintaining steel structure: electric control type or pneumatic control type

Intake valve (aluminum alloy globe valve) + sand control valve (EMPAIR air-controlled sand valve or manual sand valve).

The sand tank is always under pressure and needs to be relieved manually.

The characteristic is: no matter any switch on the spray gun, as long as the exhaust ball valve on the top side of the sand tank is not opened, the pressure in the cylinder will not be released (except for the self-discharge of the manual sand valve: it will cause serious sand accumulation in the sand pipe). ), suitable for short-term point blasting.

3) Derusting sand blasting machine for pressure relief steel structure: electric control type or pneumatic control type

Inlet valve (aluminum alloy globe valve) + sand control valve (EMPAIR air control sand valve or manual sand valve) + automatic air control exhaust valve.

When the sand tank is blasting, the pressure in the tank is the working pressure, and the pressure in the tank is 0 when it stops. It is suitable for long-term large-area blasting.

The pressure in the tank will never exceed the limit pressure, which plays the role of safety guarantee and is also a necessary assembly method for automatic sand return.

◆Working principle of pressure sandblasting machine：

The pressure-type open-type mobile sandblasting machine of Dongguan Humen Meijun Sandblasting Equipment adopts a pressure-feeding sandblasting (shot peening) mechanism, that is, the compressed air flows at a high speed in the high-pressure tank to form a high-pressure effect, and the sand in the high-pressure tank is discharged. It is sprayed through the sand conveying pipe, and then sprayed onto the surface of the workpiece at a high speed from the spray gun nozzle with the compressed air flow, so as to achieve the purpose of sand blasting cleaning.。

◆Scope of application of pressure type open mobile sandblasting machine：

Mainly used for: surface cleaning, rust removal, paint removal, oxide layer, engraving, spray processing, descaling, burr, welding scar, glass shot, strengthening the surface of decorative parts. It is a necessary process for the pretreatment of spraying and electroplating (all surface treatments to improve the adhesion of the coating surface)

The series of pressure mobile sandblasting machines are widely used in

1) Glass, marble, ceramic tile, mold, fitness and amusement equipment and other surface sandblasting cleaning and three-dimensional carving and carving operations;

2)Sandblasting for shipbuilding, surface treatment, rust removal and anti-corrosion treatment for steel structures such as bridges, railways, containers, oil pipelines, chemicals, mining facilities, water conservancy projects, port construction, etc. before painting;

3)Fancy sandblasting for denim clothing;

◆Abrasive Control:

Sand for sand blasting and rust removal requires hard particles, angular, dry and free of soil and other impurities;

Quartz sand is better, but coarse river sand is also acceptable; at the same time, sand transportation conditions, unit price, and recycling capacity should be considered

Factors such as force; the particle size of sand should be 0.5-1.5mm, and it must be dried and stored before screening

In the shed and indoors, the size of the sieve holes is: coarse sieve 40-48 holes (particle size 1.2mm), fine sieve 372-476 holes

（Particle size 0.3mm)

◆Air source requirements:

Compressed air must be treated by cooling device and oil-water separator to ensure dry and oil-free;

The oil-water separator must be cleaned regularly;

The air pressure of the air compressor is6.0×105～6.5×105Pa，The pressure change is

0.5×105～1.0×105Pa。Generally, the air pressure of the sand bucket is 4.5×105～5.5×105Pa, not less than

4.0×105Pa。

◆Operation protection requirements of rust blasting machine:

The non-sandblasted parts should be shielded and protected before sandblasting。

Before sandblasting, check whether the various pipes and control valves of the sandblasting machine are well connected, and whether they are in the appropriate switch positions.

Whether the protective tools, safety belts (ropes) and oxygen supply devices worn by sandblasters are safe and reliable, as well as the wear of the nozzles, when the orifice is worn

The nozzle should be replaced when the diameter increases by 25%.

Operation control of rust blasting machine for steel structure:

When sandblasting, the distance between the spray gun and the surface of the base steel should be 100-300mm.，

The angle between the spraying direction and the normal to the surface of the base steel is preferably 15° to 45°.

After sandblasting and rust removal, before proceeding to the next process, in case of rain or other conditions that cause the surface of the base steel to be wet, after the environment reaches the construction conditions, dry the surface moisture with dry compressed air before proceeding Sandblasting construction. If it is necessary to re-blast, the abrasive requirements cannot be reduced, so as not to reduce the roughness and cause low adhesion of subsequent spraying.
