The Shanghai Tianhe Pharmaceutical Soft Water Salt Special Tablet Press is the core equipment for soft water salt production, and its long-term stable operation relies on standardized maintenance and upkeep. Reasonable maintenance can not only extend the service life of equipment, but also ensure the accuracy of tablet pressing and product quality. The following outlines the key points of operation from three aspects: daily, regular, and special maintenance.

1、 Daily maintenance: must be done before and after starting up and shutting down every day

1. Check before startup

•Appearance and CleaningRemove the residual soft salt powder on the surface of the equipment and the feeding and discharging ports, check whether there are loose parts (such as screws and protective covers) on the machine body, and ensure that no foreign objects are stuck in the transmission gap;

•Lubrication inspectionCheck the lubricating oil level of the transmission parts (gears, bearings), and if it is insufficient, add equipment specific lubricating oil (choose 32 or 46 industrial gear oil according to the instructions) to avoid dry friction;

•Mold inspectionObserve whether there is wear, scratches or salt particle adhesion on the surface of the die. If there is slight adhesion, wipe it clean with a soft cloth dipped in water (corrosive cleaning agents are prohibited), check whether the die is firmly installed, and prevent deviation during operation.

2. Maintenance after shutdown

•Good cleaning effectDisassemble the feeding hopper and receiving tray, use compressed air to blow away residual salt powder inside, and focus on cleaning the dead corners of the pressing room to avoid salt powder getting damp and clumping, which may affect the next use;

•Parameter resetBefore turning off the power, set the parameters such as tablet pressure and speed to standby mode, and record the daily operating data (such as production and fault conditions) for easy traceability in the future;

•security checkCheck if the emergency stop button, protective cover, and other safety devices are functioning properly to ensure safety during the next startup.

2、 Regular maintenance: Weekly to monthly maintenance of key components

1. Weekly maintenance (focus: transmission and lubrication)

•Transmission systemOpen the side cover of the device and check the gear meshing. If there is wear or abnormal noise, adjust the gear clearance in a timely manner; Clean the bearings and replenish lubricating grease to ensure smooth rotation;

•Feeding systemCheck whether the spiral blades of the feeder are deformed, clean the salt deposits attached to the blades, test whether the feeding speed is uniform, and adjust the motor speed or replace the blades if there is any jamming.

2. Monthly maintenance (focus: mold and pressure system)

•mold maintenanceDisassemble the punching die, gently polish the surface of the punch with fine sandpaper to remove small scratches, soak it in anti rust oil for 10 minutes, and then air dry for installation to avoid rusting; Check the wear of the mold hole. If there are obvious steps on the inner wall of the mold hole, replace it with a mold of the same specification;

•Pressure systemCheck the accuracy of the tablet pressure sensor and calibrate it with a standard weight (the error should be controlled within ± 1%); Check if the sealing components of the pressure cylinder are leaking. If there is oil leakage, replace the sealing ring in a timely manner to prevent unstable pressure.

3、 Special Maintenance: Seasonal and Post fault Handling

1. Seasonal maintenance (with a focus on humid environments)

During rainy or high humidity seasons, place desiccants in the tablet pressing room after daily shutdown to prevent the soft water salt from absorbing moisture and blocking the mold holes; Use a hot air gun (temperature ≤ 60 ℃) to dry the inside of the equipment every week to avoid rusting of transmission components;

During the high temperature season, increase the frequency of lubricating oil inspection (once every 2 days), clean the dust on the motor cooling fan, and prevent the motor from overheating and shutting down.

2. Maintenance after malfunction

If the equipment is shut down due to material jamming, after cleaning the materials, it is necessary to check whether the punching die is deformed and whether the transmission components are offset. After repair, run it without load for 5 minutes to confirm that there are no abnormalities before putting it into production;

If there are cracks or missing corners in the tablet, in addition to adjusting the parameters, it is necessary to check the concentricity of the mold and recalibrate the position of the die to ensure even force distribution on the tablet.

4、 Maintenance precautions

All maintenance operations must be carried out with power off to avoid the risk of electric shock;

When replacing molds, seals, and other accessories, it is necessary to use original equipment accessories to prevent equipment damage caused by non-compliance with specifications;

Establish a maintenance ledger to record the time, content, and replacement parts of each maintenance, facilitating the tracking of equipment status;

Operators must undergo training before taking up their posts. It is prohibited to disassemble core components (such as pressure cylinders and motors) without authorization. For complex faults, contact the manufacturer's technical personnel for handling.

By implementing the above maintenance points in a standardized manner, the failure rate of Shanghai Tianhe Pharmaceutical's special tablet press for soft water salt can be effectively reduced, ensuring long-term stable operation of the equipment and providing reliable support for soft water salt production.
