The maintenance methods for screw conveyors should be combined with daily inspections, regular maintenance, and special working condition management, as follows:
1、 Key points of daily maintenance
1. Running status monitoring
Check whether the drive motor and gearbox are running smoothly, whether the temperature and noise are normal, and ensure that there is no shortage of oil.
Observe the gap between the spiral blades and the casing to prevent foreign objects from getting stuck (such as hard blocks larger than the pitch).
2. Cleaning and lubrication
Clean up residual materials in the conveyor tank in a timely manner after shutdown to avoid corrosion or clumping that may affect the next use.
Regularly replenish lubricating oil to rotating parts such as bearings and gearboxes to maintain good lubrication.
2、 Regular maintenance measures
1. Component inspection and replacement
Check the wear of spiral blades every six months, adjust the clearance or replace damaged friction rings and guide bars.
Clean the supporting bearings annually and replace them if they are severely worn; The steel casing needs to undergo rust prevention treatment.
2. System maintenance
The gearbox and bearings need to be disassembled and maintained every 3 years, with lubricating oil replaced and internal debris removed.
Check the interface of the conveyor belt and re bond or rivet it if necessary.
3、 Special working condition management
1. Corrosive material handling
When transporting sludge or corrosive materials, increase the frequency of stainless steel component inspections and replace worn parts in a timely manner.
2. Long term shutdown maintenance
During the shutdown period, water should be added to the slag drum to maintain lubrication and prevent component corrosion.
4、 Safety operation standards
1. Before maintenance, the power must be cut off and warning signs must be hung. It is prohibited to manually clean foreign objects or refuel during operation.
2. Avoid overloading operation and prevent motor damage due to excessive load.
The above measures can effectively extend the service life of equipment and ensure conveying efficiency.
