Standard operating procedures for daily maintenance of brick making machines

Standard operating procedures for daily maintenance of brick making machines

In order to ensure the long-term stable operation of the brick making machine, reduce failures and extend the service life, it is crucial to formulate and strictly implement a set of standardized daily maintenance procedures. This process is based on safety and emphasizes preventive maintenance.

1. Pre-shift inspection process (10-15 minutes before starting up)

The purpose of this stage is to ensure that the device has safe boot conditions.

Safety confirmation: Check whether the work area is clean and free of debris and oil.

Appearance and connection inspection:

Visually inspect all parts of the equipment for obvious damage, oil leakage, and water leakage.

Touch the key connecting bolts (such as mold fixing bolts and vibration table bolts) with your hands to confirm that they are not loose. Use tools to retighten if necessary.

Inspection of lubrication points: According to the equipment lubrication diagram, check the oil cups and oil nozzles of each bearing, guide rail, and chain to confirm that the lubricating grease is sufficient. Supplement the points that require manual refueling.

Mold and cloth system inspection: Clean the residue in the mold cavity, check whether the cloth box is clean and whether the cloth is uniform.

No-load test run: After confirming that there are no abnormalities, start the equipment without load and run it for 1-2 minutes. Listen to whether the running sound is smooth and even, and observe whether the movements of each component are coordinated.

2. Key points for mid-shift monitoring (during operation)

Sensory monitoring:

Listen: Pay attention to the sound of the equipment operating. If there is a new abnormal impact or friction sound, stop the machine immediately for inspection.

Look: Observe whether the equipment is running smoothly, whether the bricks are formed regularly, and whether the bricks are produced smoothly.

Touch (carry out after shutdown): After the equipment is shut down, touch the bearing seat, motor shell and other parts to feel whether there is abnormal high temperature.

Standardized operation: Strictly follow the procedures, add materials evenly, and avoid overload operation of the equipment.

3. After-shift maintenance process (15-30 minutes after shutdown)

The purpose of this stage is to prepare for the next day's production and eliminate hidden dangers caused by the same day's operation.

Thorough cleaning:

Clean all scattered materials and dust on and around the equipment.

Key cleaning: The mold, pressure head, cloth box, and bonded materials on the conveyor belt must be thoroughly cleaned to prevent them from affecting the next day's operation accuracy and damaging the equipment after hardening.

Inspection and tightening after operation: When the equipment is in a hot engine state, check again whether the bolts in key stress-bearing parts are loose due to vibration.

Supplementary lubrication: Supplementary lubrication for high-temperature, heavy-load operating parts (such as main drive bearings).

Mold maintenance: Clean the mold and check its working surface for damage, and apply anti-rust oil if necessary.

Fill in the inspection record: truthfully record the operating conditions, maintenance content and problems found on the shift on the "Equipment Daily Inspection Form".

4. Weekly/regular special maintenance

Performed by a mechanic or designated person on weekends or scheduled maintenance days.

Comprehensive tightening: Use tools to systematically torque check and tighten all major connecting bolts.

Transmission system inspection and adjustment: Check the tightness of the V-belt and adjust it; check the chain tension and wear; check the lubricating oil level of the reducer.

Hydraulic system maintenance (if applicable): Check the hydraulic oil level and cleanliness; clean the breather hole of the fuel tank; check the oil pipe joints for leaks.

Electrical system inspection: After power failure, check whether the terminal blocks of the main circuit and control circuit are loose; clean the dust in the electrical control cabinet.

5. Recording and exception handling

Maintenance record archiving: All maintenance, repair, and replacement parts records should be archived and saved to form an equipment "health file."

Exception handling process: Any abnormalities discovered during maintenance (such as cracks, abnormal wear, abnormal noise sources) must be reported immediately and a "to be repaired" sign must be hung, and must not be concealed.

Summary: Standardization, Routineization, and Responsibility

The core of the standard operating procedures is to "timing, fixed point, fixed calibration and fixed personnel" for maintenance work. The key to its success is persistence. Managers need to provide necessary resources and supervise implementation, while operators are the first executors of maintenance work. Investing a small amount of planned maintenance time every day is far better than long and costly repairs after a failure. Through this process, you can minimize the risk of equipment failure and ensure it is always in top working order.
