parameter:

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

Sand tank volume:0.3cubic  

Rust removal efficiency: 15-30square/Hour

Air consumption: 3立方/minute(single shot)

Air source pressure:0.6-0.7MPA

By configuration:

1)Basic:Pure manual type,Basic pressure-retaining assembly.

Intake valve(Ball valve control switch)+sand control valve(Ball valve control switch).Electric and pneumatic control systems are not installed,need2people working at the same time,One person takes a gun and blasts the workpiece,Another person controls the machine switch.

2)Pressure-holding type:electric control type or pneumatic control type

Intake valve(aluminum alloy globe valve)+Sand control valve(EMPAIRPneumatic sand valve or manual sand valve).

The sand tank keeps the pressure forever, Manual pressure relief required.

feature is:No matter what switch is 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/span>

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

3)卸压型:Electric or pneumatic control

Intake valve(aluminum alloy globe valve)+sand adjustment valve(EMPAIRair control sand valve or manual sand valve)+< /span>Automatic air control exhaust valve

Sand tank during sandblasting work,The pressure in the tank is the working pressure,Automatic exhaust at shutdown,pressure in the tank is 0,suitable for long-term large-area sandblasting.

The pressure in the tank will never exceed the limit pressure,act as a security guarantee,At the same time, it is also a necessary assembly method for automatic sand return.

 With the inner wall sandblaster, the inner wall of the pipeline can be blasted and cleaned.

The series of pressure mobile sandblasting machines are widely used in sandblasting and three-dimensional carving of glass, marble and other stone materials.,Shipbuilding Sandblasting,Surface treatment of steel structures such as bridges, railways, containers, and petrochemical facilities before painting, Rust removal and anti-corrosion treatment and fancy sandblasting for denim clothing.

1,Compact structure,superior performance,easy to operate,convenient.

2,The design and production of the cylinder body conform to the pressure vessel standard,safe and reliable.

3,Using standard universal parts,easy to replace,less cost.

4,Add instant control function,Adopt electric control or pneumatic control,to meet the different needs of customers,Can be operated by one person.

5,Shell is sandblasted and uses advanced anti-rust paint, to prevent rust.

6,Add wheels , easy to move.   

Abrasive control; Sand for blasting and rust removal requires hard particles, angular, dry and free of mud and other impurities;

Quartz sand is better, coarse river sand is also acceptable; at the same time, sand transportation conditions, unit price, and recovery energy should be considered.

Factors such as force; the particle size of the sand is equal to 0.5～1.5mmIt is advisable to dry before screening and store

In the shed and indoor, the sieve size is: coarse sieve40～48hole(particle size1.2mm）、fine sieve372～476孔

（particle size0.3mm)

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

0.5×105～1.0×105Pa。The general sand bucket air pressure is 4.5×105～5.5×105Pa，must not be less than

4.0×105Pa。Before sandblasting, check whether the various pipes and control valves of the sandblasting machine are connected , is in the appropriate switch position,

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

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

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

The oil-water separator must be cleaned regularly to avoid the distance from the nozzle to the surface of the base steel.100～300mmsuitable,

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

The angle between the spray direction and the normal to the surface of the base steel is15°～30°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, use a dry

Construction after drying the surface moisture with compressed air. If sandblasting is necessary, the abrasive requirements cannot be reduced to avoid reducing the roughness。
