The medium concrete mixer can mix plastic, dry hard, fluid concrete and light aggregate and mortar, so daily maintenance and repair are essential.
1. The body of the medium concrete mixer must be kept clean and the dirt and obstacles in the body must be removed.
2. Check the oil and circuit and control equipment of each lubricating place before working every day, and add lubricating oil as required.
3. The medium concrete mixer must be implemented with secondary leakage protection. After the power is turned on before work, it must be carefully checked. It can be used only after it is considered qualified by the empty car test.
4. Before daily work, you must check whether the transmission clutch and brake are flexible and reliable, whether the steel wire rope is damaged, whether the track pulley is in good condition, and there are obstacles around and lubrication of various parts around.
5. Before working every day, add water to the mixing drum to idle for 1 to 2 seconds, and at the same time check the reliability of the clutch and brake device.
6. During the operation of the medium concrete mixer, you should always check whether the noise of the motor, reducer, and transmission gear is normal, and whether the temperature rise is too high.
7. After each start-up of the mixer, you must check whether the operation of each part is normal. When shutting down, remember to check whether the blades of the mixer are bent and whether the screws are loose or loose.
8. After each work, the concrete mixer must be carefully cleaned.
Under normal circumstances, medium concrete mixer need maintenance after working for a period of time. In addition to the daily maintenance work, further maintenance, inspection and adjustment of brake clearance are required. For example, the inner and outer brake bands of the clutch are worn out and need to be replaced. Adjust the gap between the stirring blade and the scraper and the liner. The sealing and flexibility of the upper hopper and discharge door. The degree of clutch wear and the algorithm of the water distribution system are normal. Concrete mixers using chain drives also need to check the elongation of the chain pitch.
