JB-300B/500B semi automatic pendulum impact testing machine faults and exclusion

1, hook into pressure damping rod, the micro switch is in a relaxed state, but the motor does not stop.

To find out the reasons:

A. switch 1WK action is not reliable or broken

B. 4J action relay

Do not release the C. contactor

Troubleshooting:

A. 1WK and 4J

B. cleaning 1C contactor armature

2, linked to the pressure damping rod, the motor has been stopped, but the pendulum does not fall on the hook, press the "impact" button, the valve with the electromagnet has action, but the pendulum does not fall.

Search cause:

A. electromagnetic clutch armature off

Several key and end key "B. armature don't interest" more than the spring force

C. spring force is small or fatigue

D. brush contact

Elimination method:

A. open the side cover, add a few drops of oil in the end key and keyway slide and screw knife struck several times

B. replacement spring

C. repair brush

3, according to the "pendulum" button pendulum does not move.

To find out the reasons:

A. may be loose belt

B. power failure

C. relay switch fault WK

Troubleshooting:

A. tighten the belt

B,Check fuse
