2.3 Supply (gas) requirements ASTM D3170

2.3.1 Power supply requirements

1.AC 220V;

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

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

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

2.3.2 Air supply requirements

Compressed air is needed when the equipment is running, and the pressure is 0-0.8mpa.

3.3.1. Introduction of serial number and name on the equipment operation interface

The feeding system is composed of feeding motor + feeding funnel + other accessories

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

3. The bin baffle is used to block the impact medium and control the flow velocity of the medium

The spray gun assembly is used to provide the specified air flow pressure and mix with the medium to spray the medium to the table of the tested sample

The power switch opens and closes the instrument

6 pressure knob Adjust the impact pressure knob (increase the pressure clockwise)

7 emergency stop switch When the machine is in a dangerous state, the emergency stop switch is used to cut off the power supply and stop the operation of the equipment, so as to protect the safety of human and equipment

The adjusting knob of the pneumatic vibrator is used to adjust the pressure of the bin vibrator, so as to control the flow velocity of the impact medium

7PLC used to display the operation interface 3.3.2 Gun introduction

Serial name introduction

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

2 mixing chamber where high pressure air and medium mix (that is, when the medium falls, the compressed air passing through flows according to the direction of airflow)

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

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

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

Gun installation is used for gun installation. It is simple, fast and safe

3.4 Operating method of testing machine

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