Common faults of hook shot blasting machine

- 2022-02-25-

1. The dust of the dust collector contains too many projectiles

Measures: If the air volume is too large, adjust the tuyere baffle appropriately until dust removal can be ensured, but it is advisable to avoid steel sand.

2. The cleaning effect is not ideal

measure:

1. The supply of projectiles is insufficient, increase the projectiles appropriately

2. The projection direction of the second shot blasting machine is incorrect, adjust the position of the directional sleeve according to the instructions

3. There is a slip phenomenon when the elevator lifts the material

Measures: adjust the drive wheel, tension the belt

4. The separator has abnormal noise

Measures: Loosen the inner and outer bolts, tighten the belt

5. The screw conveyor does not send sand

Measures: See if the wiring is correct and reversed

6. The machine starts and stops insensitively or does not act according to regulations

Measures: 1. The relevant electrical components are burned out, check and replace

2. There is too much dust and dirt in the electrical box, and the electrical contact points are in poor contact

3. If the time relay fails, change the time relay, and it is strictly forbidden to adjust the time when driving

7. The hook does not turn or the rubber wheel slips

measure:

1. The weight of the cleaned workpiece exceeds the specified requirements

2. The gap between the rubber wheel and the hook of the reducer is unreasonable, adjust the rotation mechanism

3. The reducer or line is faulty, check the reducer and line

8. The hook goes up and down, and the walking is not flexible

measure:

1. The limit or travel switch is damaged, check and replace

2. The electric hoist is damaged, repair the damaged part

3. The weight of the hook is too light

9. The shot blasting machine vibrates greatly

measure:

1. The blade is seriously worn and the operation is unbalanced, and the balance should be found when the blade is replaced with symmetry or composition.

2. The impeller is seriously worn, replace the impeller

3. The fixing bolts of the shot blasting machine are loose, and the bolts are tightened

10. There is abnormal noise in the blast wheel

measure:

1. The specifications of the steel grit do not meet the requirements, resulting in the phenomenon of sand sticking, and replace the qualified steel grit

2. The inner guard plate of the shot blasting machine is loose, and it rubs against the impeller or impeller blade, adjust the guard plate.
