1. Comply with the general operating procedures of shot blasting machine casting equipment 。
2. Before work, you must also observe:
For severe wear of blade and guide wheel, the maintenance personnel shall be informed of the serious wear and tear of the guide wheel
B. check whether the iron shot conveying system, such as the elevator, spiral conveyor screen (or multi angle screen), sand bucket and shot conveying pipe, is blocked or jammed. If there is any such phenomenon, it shall be handled in time
C. check whether the suspension chain and auxiliary chain are loose and derailed. If there are such phenomena, the maintenance personnel shall be informed to repair
D. check whether there is any casting falling in the shot blasting room, and if there is any, it shall be removed in time
E. check the integrity of the protective curtain and protective plate, and do not allow the lack of or excessive wear, otherwise they should be replaced
F. check whether the suspension chain hook is seriously worn and whether the rotation is flexible. If the wear is severely punished or the rotation is not flexible, timely replace or inform the maintenance personnel for repair
G. start each mechanism separately, check the motion of the polishing head, iron shot conveying system, auxiliary chain and suspension chain, and confirm that everything is normal before production.
3. Each worker must also observe:
A. operators should take protective equipment to avoid iron shot injury
B. start the equipment in the following order:
(3, 6) - chain hoist. The stop sequence is opposite, namely suspension chain - iron shot gate - auxiliary chain - throwing head - spiral screen (or multi angle screen) - hoist - fan.
C. the casting of 30 hooks must be hung on the suspension chain before the casting can be cleaned on one side and hung continuously on the other side
D. start the test run by inching, and then run for 3-5 minutes without load. Check the working stability of shot blasting head, screw conveyor, elevator, winch and chain plate belt, and confirm that everything is normal before production.
3. It is also necessary to observe:
A. when working, operators should take protective equipment to avoid iron shot injury
B. start the machine according to the following sequence: start the fan - open the rolling gate - start the feeding bucket - click the chain plate belt - reset the feeding bucket - close the rolling gate - start the chain plate belt - start the shot blasting head - start the screw conveyor - start the hoist - open the iron shot gate.
Stop in reverse order
C. always pay attention to the stability of the projectile head movement. If the projectile head vibrates greatly, the maintenance personnel shall be informed to repair.
D. the weight of each casting is not more than 500 kg and not less than 300 kg, depending on the size and shape of the casting
E. according to the consumption of iron shot, add new iron shot frequently, and pay attention not to crush the elevator
F. when the shot blasting head is working, the chain plate shall not move in reverse direction
G. when the shot blasting head is working, it is strictly forbidden to open the drum door
H. when the shot blasting head is working, the movement of screw conveyor and elevator shall not be stopped.
