Steel structure processing blasting machine

Details

Steel structure processing sand blasting machine parameters:

Sand cylinder diameter: 600MM Sand cylinder height: 1300MM

Sand tank volume: 0.3 cubic

Descaling efficiency: 15-30 square / hour

Air consumption: 3 m3 / min (single shot)

Air source pressure: 0.6-0.7MPA


Divided by configuration:

1) Basic type: pure manual type, which is basically a pressure-proof assembly.

Intake valve (ball valve control switch) + sand control valve (ball valve control switch). Without electronic control and pneumatic control system,

It requires 2 people to operate at the same time, one person blasts the workpiece with a gun, and the other person controls the machine switch.

2) Holding pressure type: electric control type or pneumatic control type

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

The sand tank always maintains pressure and needs to be manually depressurized.

The characteristic is: No matter whether the switch is turned on or off once, 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 removed.

(Except for manual sand valve self-draining: it will cause serious sand accumulation in the sand pipe), suitable for short-time point blasting.


3) Pressure relief type: electric control type or pneumatic control type

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

When sand blasting works, the pressure in the tank is the working pressure. When the tank is stopped, it is automatically vented. The pressure in the tank is 0, which is suitable for long-term large-area blasting.

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



Pressure mobile sand blasting machine products are widely used in sand blasting and three-dimensional carving of glass, marble and other stone materials, sand blasting for shipbuilding, bridges,

Surface treatment of steel structures such as railways, containers, petrochemical facilities, etc. before coating, rust removal and anticorrosive treatment, and fancy sandblasting of denim clothing.

1.Compact structure, superior performance, simple and convenient operation.

2.The design and production of the cylinder body comply with the pressure vessel standard, which is safe and reliable.

3.Using standard universal parts, easy to replace and lower cost.

4.Instantaneous control function is installed, which adopts electric control or pneumatic control to meet different needs of customers and can be operated by one person alone.

5, the shell is sandblasted and uses advanced anti-rust spray paint to prevent rust.

6, add wheels, easy to move.


Abrasive control; sand used for sandblasting and rust removal, which requires hard particles, edges and corners, dry and free of dirt and other impurities;

Quartz sand is better, but coarse river sand is also available. At the same time, sand transportation conditions should be considered.

Force and other factors; the particle size of the sand is preferably 0.5 ~ 1.5mm, it should be dried and stored before screening

Inside and inside the shed, the size of the sieve holes are: coarse sieve 40 ~ 48 holes (particle diameter 1.2mm), fine sieve 372 ~ 476 holes

(Particle diameter 0.3mm)


During the blasting operation, the air pressure of the air compressor is 6.0 × 105 ~ 6.5 × 105Pa, and the air pressure range is

0.5 × 105 to 1.0 × 105Pa. General sand bucket pressure is 4.5 × 105 ~ 5.5 × 105Pa

4.0 × 105Pa. Before blasting, check whether the various pipes and control valves of the blasting machine are connected, whether they are in the appropriate switch position,

Is the protective tool, safety belt (rope) and oxygen supply device worn by the blaster safe and reliable, and the wear of the nozzle, when the orifice

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


The compressed air must be processed by a cooling device and an oil-water separator to ensure that it is dry and free of oil;

The oil-water separator must be cleaned regularly. The distance between the nozzle and the surface of the base steel is preferably 100 ~ 300mm.

Before sand blasting, the non-blast blasting parts should be protected.

The angle between the spray direction and the surface normal of the base steel is preferably 15 ° ~ 30 °. After sandblasting and rust removal, before 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, use a dry

Compressed air is used to dry the surface after construction. If sand blasting is required, the abrasive requirements must not be reduced to avoid reducing the roughness.
