First, the wave soldering process, wave soldering nozzle does not move there are four reasons

1, the driver damage causes: the driver itself is damaged, or because the drive temperature is too high to cause the drive to protect, no output;

Approach: replace the drive.

2, bad motor, replace the motor.

3, the connection is loose, the connection at the connector loose, leading to poor contact, adjustment can be.

4, mechanical stuck cause:

a, spray car synchronization wheel deformation, serious wear and tear;

b, small bearings within the synchronous wheel damage;

c, synchronous belt disconnected or too loose;

d, synchronous belt with the Department of wheel installation is not balanced;

e, synchronous belt with the Department of the wheel bearing damage.

Approach:

a, replace the spray car synchronization wheel;

b, replace the small bearing;

c, adjust

d, adjustment

e, replace.

Second, in the wave soldering process, can not spray the flux reasons:

1, the nozzle blockage

2, adjust the flow of the nozzle adjustment nut locked;

3, tracheal rupture;

4, no flux

5, no air supply;

6, solenoid valve is bad.

Approach:

1, cleaning and maintenance of the nozzle;

2, can be adjusted;

3, replace the trachea;

4, add flux;

5, open the external gas source;

6, replace the solenoid valve.
