When using an automatic wet shotcrete machine, sometimes the phenomenon of non-wet spraying may occur. Once the wet spraying cannot be performed, how to troubleshoot the problem? The following answers for you.
1. First, check whether the power supply is normal and the motor is burnt out;
2. Check whether the reducer and gear oil pump are faulty and the rotation direction is correct;
3. Turn on the pressure gauge switch of the wet shotcrete machine, release the pressure regulating wheel of the overflow valve, and check whether the pressure reaches the wet spraying requirement;
4. Put the suction tube in clean water and check whether the wet nozzle can suck the slurry normally;
5.Check whether the hydraulic directional valve block can control the reciprocating movement of the cylinder and whether the movement is blocked;
6. Finally, start the motor and adjust the wet shotcrete machine pressure of the wet sprayer to 1 ~ 2Mpa. Check the entire wet spraying link one by one to see which link has an abnormal phenomenon.
