How long should the concrete mixing station need to be maintained
With the increasing demand for concrete in the market, the production and operation of concrete mixing plants is also continuously increasing. The key to ensuring the normal operation of concrete mixing plants is that the operation and management personnel regularly maintain and maintain the concrete mixing stations, not only It is related to the progress of the project and also has an inseparable relationship with the profit of the project. In order to ensure the normal operation of the concrete mixing plant equipment and give full play to its benefits, the concrete mixing plant equipment should be properly repaired and maintained. How often does the concrete mixing station be maintained.
Concrete mixing plant
1. Check each time before using concrete mixing station
Check whether the air compressor self-protection device in the concrete mixing station is reliable, whether the air pressure is stable; check whether the water pump water supply is sufficient, and whether the pipeline is unblocked; whether the material warehouse door, cement door, intermediate collecting hopper door, discharge door, etc. are opened or closed Flexible and reliable; check whether the coupling bolts of the mixing machine blades are firm; check whether the electrical devices are safe and reliable, and whether the limit switch action switches are flexible and reliable; check whether the lubricating gears of each lubrication point have sufficient lubricating oil.
2, after each shift after use
Clean the inside and outside of the concrete mixer, and accumulate the material on the material door, and rinse it; add lubrication points to each lubrication point, especially the shaft end seal, and do not miss it; in winter, the liquid in the water channel should be drained; Gas and water in the cylinder; all switches are inactive after shutdown and the power is turned off.
3, weekly inspection and maintenance
Check the condensation of residual enthalpy in the mixing tank. If there is condensation, stop it and remove it (note that the power supply should be cut off), check the gap between the mixing blade and the lining plate. If it is not suitable for adjustment; check whether the pneumatic system is leaking or not. Whether it is reliable; check the quality of the lubricating oil in the gearbox and the height of the liquid level, if necessary, fill or replace; check whether the water suction bottom valve in the water supply system is reliable; check whether the electrical components are damaged, repair or replace if necessary, check Whether the wiring is loose; unscrewing the fouling, checking the sealing of the shaft end, and screwing in the plug after no abnormality.

4, inspection and maintenance around
Check the tension of the belt of the concrete mixing station and make appropriate adjustments; check the wear of the blades and linings; check whether the connecting bolts of the upper and lower frames, the silo, the large inclined belt machine, etc. are firm, and whether the foundation is under Sink; check the concrete mixing plant equipment - whether there are agglomerations and debris in the screw conveyor, if any, remove.
5, annual inspection and maintenance and overhaul of concrete mixing plant
The concrete mixing plant equipment is operated for one year. In addition to the inspection of items 1, 2, 3 and 4, other parts should be inspected and inspected, repaired and replaced.
