Release time:

2024-07-04

Check once a week whether the discharge door leaks, whether the sealing strip is damaged, and whether the discharge linkage mechanism is at the dead center position when closing the door.

1. Safety Regulations

1. The protective cover of the mixer drive chain should be in good condition to prevent personal injury accidents caused by people touching the chain at work.

2. The fastening bolts of the motor base should be checked regularly, and the foundation should have sufficient rigidity to prevent the chain from jumping or falling off due to the loosening of the foundation, resulting in transmission failure.

3. When inspecting, repairing and maintaining the machine, the power supply must be cut off and signs must be hung.

4. It is strictly forbidden to put hands or other tools into the machine during the operation of the machine.

Only after the machine is completely stopped can the machine be cleaned and inspected.

6. Cables and wires shall be provided with protective sleeves.

2. Maintenance Procedures

1. During operation, check the compressed air pipeline for air leakage at least once per shift, and discharge the accumulated water in the oil-water separation trio once.

2. Check once a week whether the discharge door leaks, whether the sealing strip is damaged, and whether the discharge linkage mechanism is at the dead center position when closing the door.

3. Clean the residual materials attached to the inner wall of the buffer bucket once a week.

4. Scrub the transmission chain and sprocket with diesel once a month, and refresh the engine oil for the chain sprocket.

5. Clean the fuel injection nozzle once a month, and clean the remaining attached materials on the inner wall and cover plate of the mixer at the same time.

6, once a month to determine the coefficient of variation of the mixer outlet and finished product packaging mouth, the determination of the coefficient of variation should select the product with the shortest mixing time.

3. Maintenance Procedures

minor repairs

Mixer minor repairs every six months, including the following

1. Check whether the wire connection in the motor junction box is loose.

2. Clean up the residual materials attached to the inner wall of the mixer and buffer hopper.

3. Clean up the oil-water separation trio to ensure smooth gas path.

4. Check the wear of the pin shaft at each hinge point of the unloading linkage mechanism, and replace the pin shaft with serious wear to ensure the reliability and stability of the linkage mechanism.

5. Replace the sealing strip of the discharge door, check the reliability of the limit stroke of the switch door and adjust its position to ensure the sealing of the discharge door.

6. Check the tightness of the transmission chain and the fastening of the motor seat, and adjust the chain tensioner or the motor base to keep the chain at a proper tension.

7. Replace the reducer grease.

Medium repair

Mixer medium repair once a year, including the following

1. All minor repairs.

2. Clean up the wear of the rotor and the gap between the rotor and the object, repair or replace the seriously worn belt or blade, and adjust the gap between the rotor and the housing to the allowable range (about 5mm).

3. Clean the main bearing and bearing seat, check their wear, replace them if necessary, and fill the bearing with lubricating oil.

4. Check the wear of the cylinder and replace the severely worn parts.

5. Check the compressed air pipeline, especially the aging of the hose, and replace it if necessary.

6. Remove and wash the reducer, check the wear of each part, replace the worn parts if necessary, and add grease to the reducer.

7. Check the wear of the transmission chain and sprocket, and replace it if necessary.

8. Check the wear of the motor bearing and add grease to the motor bearing.
