What is The Difference Between Summer And Winter Maintenance of Concrete Mixing Plants?

There are significant differences in the maintenance of concrete mixing plants in summer and winter, which is mainly due to the different climate conditions in the two seasons. The following is a detailed description of the difference between summer and winter concrete batching plant maintenance:

I. The impact of temperature on equipment

Summer

High temperature and high humidity environments can easily cause equipment to rust and corrode, especially the suction pipe, around the sleeve, and the inner rod of the mixer.

High temperature will also affect the heat dissipation performance of the equipment, such as the heat dissipation of the mixing box and reducer.

Winter

Low temperature environments can easily cause moisture in the equipment to freeze, thus damaging the pump and its pipelines.

Cold weather will also affect the starting performance of equipment. For example, motors and water pumps may not start due to ice.

II. Differences in maintenance measures

Summer

Anti-rust treatment: With high temperatures and high humidity in summer, the metal parts of the concrete mixer are prone to rust. Therefore, frequent inspections and anti-rust coatings are required to prevent metal parts from rusting.

Heat dissipation management: With high temperatures in summer, the heat dissipation system of the concrete mixing plant requires special attention. Especially the mixer box and reducer need to ensure good heat dissipation to prevent overheating damage. Try to place the mixer in a well-ventilated place, and arrange the working time reasonably to avoid overheating caused by long-term continuous operation.

Regularly check and adjust the tension of the mixer belt and the looseness of the bolts.

Winter

Antifreeze treatment: When the temperature is low in winter, the water pump, water tank, additive pump and other components of the concrete mixing station are prone to freezing. Therefore, after the operation of the equipment is completed, the water and residues in the water pump, additive pump, water tank, and additive tank need to be drained to prevent freezing. If the equipment freezes, you need to use hot water to thaw the pump body, etc. Do not force it to start. If the water pump freezes, water the pump body with hot water until the motor shaft can rotate freely.

Insulation measures: In winter, the equipment of the concrete mixing station needs to be insulated to prevent equipment damage due to low temperatures. In particular, the inside and outside of the mixing tank wall of the mixer, the discharge port, etc. need to maintain a certain temperature to prevent concrete from condensing.

Start-up inspection: When the concrete mixing plant is not used for a long time in winter, it needs to be turned on twice a week for about half an hour each time to prevent frostbite or difficulty in starting the equipment due to long-term non-use. Start the additive pump of the water pump and run it for a minute or so to drain out any residual moisture. Regularly check the joints of the water supply pipeline to prevent water from freezing in the joints.

Lubrication and cleaning: In winter, it is also necessary to regularly check the lubrication condition of the mixer's rotating shaft and perform grease lubrication. At the same time, it is necessary to clean up the debris and residual materials in the mixer to keep the equipment clean.

Electrical system inspection: Although winter is not as rainy as summer, it is still necessary to check whether the electrical system is safe and reliable, especially whether various electrical devices, wiring, etc. are loose or damaged.

III. The difference between lubrication and cleaning work

Summer

Cleaning and Maintenance: Cleaning is also done more frequently to prevent dust and residue from causing damage to the equipment. After the concrete mixer is operated in summer, the concrete in the mixing tank should be cleaned immediately to prevent it from solidifying in the tank and affecting the working performance and life of the mixer. Use stone slurry mixed with water to roll in the mixing tank for a period of time and then release it to thoroughly clean up the residue.

Lubrication inspection: Due to the high temperature and high humidity environment, the evaporation and oxidation of lubricating oil are accelerated, so the lubricating oil needs to be checked and added more frequently. Regularly check the lubrication condition of the mixer's rotating shaft and lubricate it with grease as needed.

Electrical system inspection: It is rainy in summer. It is necessary to check whether the wires and plugs connecting the mixer to electricity are damp or damaged to ensure the safety and reliability of the electrical system. Be sure to protect yourself from rain, especially the electrical cords and plugs where the mixer is connected to electricity.

Winter

Lubrication inspection: Due to low temperature environment, the fluidity of lubricating oil becomes poor, so it is necessary to select lubricating oil suitable for low temperature environment and ensure that the lubrication points are well lubricated. Regularly check whether the lubricating oil at each lubrication point is sufficient, and whether the lubricator in the air system maintains sufficient oil volume.

Cleaning and maintenance: Cleaning is equally important, but care needs to be taken to prevent moisture from freezing and causing damage to the equipment. Although concrete is not easy to dry and solidify in winter, it is also necessary to regularly clean up debris and residual materials in the equipment to keep the equipment clean. Pay special attention to cleaning the inside and outside of the mixing tank wall, the discharge port and other places where dust and residue are likely to accumulate.

Summary

There are some differences between the maintenance of cement concrete mixing stations in summer and winter in terms of the impact of temperature on equipment, maintenance measures, lubrication and cleaning work. Therefore, when maintaining the concrete batching plants, it is necessary to formulate corresponding maintenance plans according to seasonal characteristics to ensure the normal operation of the equipment and extend its service life.
