This machine uses 19mm inner diameter sandblasting pipe and wear-resistant straight-hole boron carbide sandblasting nozzle (non-Venturi and other large-scale spray guns) for air supply and sand discharge. It is mainly suitable for glass stone carving and narrow area sandblasting.

Compared with other pressure sandblasting machines with an inner diameter of 32MM, it has the characteristics of saving air source and cost.

Sandblasting grade: SA2.5-3.0    Air compressor power: 15HP  

  Installation
1. Please roughly check the screws and parts of the machine to see if they are loose or damaged by collision. If so, please replace them with new ones or fix them firmly.
2. Connect the high pressure pipe between the air compressor and the sand blasting machine, and connect the pipe of the momentary switch according to the corresponding standard test number. (Note: Before connecting the air pipe, it is necessary to first remove the sundries or excess water in the pipe [hold the air pipe upward with your hand, open the air source to blow out the sundries in the pipe, and then close the air source], and then connect the air pipe to the machine. , so as not to cause damage to pressure regulation, water filtration, and injection control. It is also recommended that manufacturers install a freeze dryer to ensure the quality of air and reduce avoidable failures).
3.[Sandblasting pipe and instantaneous control device are not combined] Keep the air inlet switch of the pressurized barrel closed, and open the air inlet switch to supply air to the air compressor, then press down the trigger of the instantaneous control switch to let the instantaneous control Lift the pressure rod up, insert the sandblasting pipe from the hole of the momentary switch, and pass the sandblasting pipe through the momentary switch.     (openable and closeable instant control switch, please open the instant control mechanism and insert the sandblasting pipe)
4. After the above actions are completed, after adding the sand material, close the air release valve, open the pressure barrel, the machine ready to use.
 
Standard operating procedure for adjusting the sand output
Note: After adjusting the sand output, it depends on the length of the sand blasting amount. It takes an extra minute for each meter of sand pipe to see the adjustment. The amount of sand produced after the change.
If it is equipped with a pipe press, please pay attention to the working conditions of the pipe press:
1. Under normal circumstances, the handle of the sand control valve is fully opened, and the sand output is the largest at this time, the flow of sand material is thick, and the sand material Fast flow.
2. Fully closed, no sand is generally produced; in normal work, the handle is only opened at a small angle; in general, it is opened about 30 degrees, so that it is easy to operate, but it also depends on the diameter of the nozzle, the operator Adjust the angle according to the skills, operating conditions and sand production requirements.

3. The angle is between fully open and fully closed according to the actual situation, and the amount of sand produced is adjusted with the angle.
