Pressure type mobile sand blasting machine
600 sand cylinder diameter
Holding pressure pneumatic control type:
Features: The sand blasting machine operates automatically for each operation and is operated by one person, which is simple and convenient.
Pressure mobile sand blasting machine is a kind of thermal spraying pre-processing machine, which uses compressed air as the power to spray clean and dry abrasive at high speed to the surface of the workpiece to be sprayed to achieve surface cleaning,
For texturing requirements, it can also be used for paint removal, welding seam rust removal, preparation of texturized glass and other workpieces. The effect is very significant. The cleaning level reaches SA2.5-3.0, and its roughness reaches
Process requirements. The product has a wide range of uses, compact structure, simple maintenance, easy to use, etc. It is a necessary machine for thermal spraying (welding) various anticorrosive layers.
The pneumatic remote control system of the pressure-holding pressure mobile sand blasting machine is composed of an air shut-off valve, a control air pipe, a manual control switch and an air-controlled sand control valve assembly.
When working, the handle is depressed, and the air flow is controlled to reach the manual control switch through one air pipe (the A port on the shut-off valve), and is discharged to the air inlet (port B) on the shut-off valve through the other air pipe, so that
The inlet valve of the main pipe in the shut-off valve is opened to open the air source channel into the sand cylinder and the main air pipe on the side of the cylinder. At the same time, the air source outside the B port is teeed through the exhaust port (c port) on the stop valve.
Punch out to the sand control valve, the sand control valve opens, at this time the pressure in the sand cylinder rises, and the sand-gas mixture is extruded from the bottom of the cylinder through the inner hole of the open sand valve rubber core to the sand tee, and the sandblasting operation starts.
The characteristic of this model is that each time the valve is opened, the air shut-off valve (intake valve) and the air control sand control valve must be activated, the gas of the blasting cylinder will increase and discharge, and each time the switch
There is a certain period of time, because the operator has to lower the nozzle because the gas from the blasting cylinder is completely discharged.
Due to the use of pneumatic remote control abrasive valve, the sand regulating valve is normally closed when shutting down. When starting up, the air pressure impacts the rubber lining in the sand valve, and the striker against the rubber core in the I-shaped seat will loosen. The beam will return to the position.
Open. Therefore, every time the switch is opened, there will be a certain amount of storage in the sand tube, and there will be a momentary pulse when firing.
This system is not suitable for sandblasting operations longer than 20m, because the pneumatic remote control reaction has a lag time. For sandblasting operations longer than 20m, it is recommended to add a power distribution control system, which can greatly
Reduce reaction time. If it is necessary to use pneumatic control, it is better to use a manual butterfly sand adjustment valve with 45 degrees of sand output, and also have to endure a delay of 3-5 seconds, or use our new air interceptor.
Check valve (new design, add control pipe instantaneous exhaust hole D port), can exhaust instantly, reduce delay, 1 second can produce control response.
