Conform to the standard

2.3 ASTM D3170 is required for power supply (gas)

2.3.1 power supply requirements

1. AC 220 v;

2. Allowable fluctuation range of voltage: AC220V(1±10%)

3. Permissible range of frequency fluctuation :(1±1%)50Hz

4. The user is required to configure the air or power switch with corresponding capacity for the equipment at the installation site, and the switch must be independently dedicated to the power supply capacity of the equipment with a capacity of 500W and a maximum current of 5A

2.3.2 gas supply requirements

Compressed air is required for the operation of the equipment at a pressure of 0-0.8mpa.

3.3.1. Schematic diagram of device operation interface

Introduction to serial name

The feeding system consists of feeding motor + feeding funnel + other accessories

The adjustable impact box is used to realize the impact test area of the tested sample

3 storehouse baffle is used to stop the impact medium and control the flow rate of medium

The spray gun assembly is used to provide the specified air pressure and mixing with the medium to spray the medium to the table of the sample under test

Power switch on and off the instrument

6. Pressure knob to adjust the impact pressure knob (increase the pressure clockwise)

Emergency stop switch when the machine is in a dangerous state, cut off the power through the emergency stop switch to stop the operation of the equipment, so as to protect the safety of the person and the equipment

8. Pneumatic vibrator adjusting knob is used to adjust the pressure of the silo vibrator, so as to control the velocity of impact medium

7PLC is used to display the operation interface

Introduction to serial name

The inlet pipe of the gun is used for the high-pressure resistant pipe of the gun inlet, which is a movable part and easy to be disassembled

2 mixing chamber where high-pressure air and medium are mixed (that is, when the medium falls, the compressed air passing through flows in the direction of airflow)

The gun barrel is used to ensure the pressure, flow rate, flow rate and direction of the medium passing through the mixed high-pressure air and medium

4. The feeding port medium enters the mixing chamber through this place, and the feeding state can also be observed through this place

Pressure check tube is used to check the injection pressure value, connected with pressure gauge

Gun installation for gun installation, easy, fast and safe

3.4 operation method of testing machine

Note: wear protective eye mask and noise-cancelling earphone before test!!!

First connect the gas storage tank and impact meter

Choose impact box (impact box with adjustable Angle and 3D impact box) according to the standard. If choose impact box with adjustable Angle, adjust impact Angle (45°, 54° or 90°) according to the standard requirements.
