Troubleshooting of foaming equipment: 

1. 

The air switch or thermal relay tripping in the electric box during the operation of the foaming equipment. 

1 the connector in the motor or electric box is loosened to check and tighten the wire connector. 

2 the slurry is too thick, the mixer load the slurry and reset the "red" button on the thermal relay. 

(3) check the cause of low voltage and increase the voltage to the specified value. 

two。. 

When the high pressure foaming machine is working normally, the pressure reducing valve above the air bag suddenly vents a large amount of air. 

1 the pressure relief valve is broken, check and replace the pressure relief valve. 

2 the slurry in the mixing tank is too thick, resulting in the air pressure higher than the pressure reducing valve bearing capacity to stop diluting the slurry. 

3. 

When the foaming equipment is working normally, the effluent from the outlet suddenly thickens or thinns and contains air. 

1 the slurry level in the mixing tank is too low, the pump inhales the air and after the machine stops, the air is discharged inversely and the material is added to the mixing tank. 

(2) the foaming liquid in the liquid supply tank was emptied and checked and adjusted to the foaming liquid. 

Check if the air line is leaking and the pressure reducing valve is broken and repaired. 

(4) the bushing is worn too much and the new bushing is replaced. 

4. 

When the foaming equipment is working normally, the noise of the screw pump suddenly increases. 

1 the bushing goes into the solidified cement block or other solid cement block to stop and check and remove. 

2 the screw shaft bolt may be broken, checked and replaced.
