The correct use of the automatic mixing machine is conducive to the smooth construction, and can improve the work efficiency of the project. If not properly used, it will damage the mechanical parts of the equipment and reduce its service life. The most important thing in use is to operate in strict accordance with the instructions. Generally in summer, if the temperature of the automatic mixing machine is too high, it should stop immediately and continue to use after the temperature drops down.
1. When operating the automatic mixing machine, pay attention that the pressure of the hydraulic system should comply with the provisions in the operation manual, and should not be adjusted at will. The quality and quantity of hydraulic oil should meet the original requirements.
2. Before operating the automatic mixing machine, pay attention to drain the residual water and sundries in the mixing drum before loading. In the process of transportation, keep rotating to prevent concrete segregation. Before the concrete mixer truck arrives at the construction site and unloads, the mixing drum shall be rotated at full speed at 14-18 rpm for 1-2 minutes, and then reverse unloading shall be carried out. Before reversing, the mixing drum should be stopped stably, and then turn on the reversal.
3. If the ambient temperature is higher than + 25 ℃, the duration from loading, transportation to unloading shall not exceed 60 minutes; if the ambient temperature is lower than + 25 ℃, the above time shall not exceed 90 minutes.
4. During winter construction, it is necessary to check whether there is icing before starting the machine; when off duty, carefully remove the residual water in the mixing drum and water supply system, turn off the water pump switch, and put the control handle at the "stop" position.
5. After unloading at the construction site, the inlet hopper, discharge hopper and discharge chute should be flushed with the hose attached to the equipment to remove the sludge and concrete adhering to the vehicle body. On the way back to the mixing station, 150-200l water should be injected into the mixing drum to clean the concrete residue bonded by the cylinder wall and blades.
6. At the end of each day's work, the driver should be responsible for injecting fresh water into the mixing drum of the automatic loading concrete mixer, rotate it at high speed (14-18 RPM) for 5-10 minutes, and then drain the water to ensure the cleanness of the drum. When cleaning each part of the mixing drum with high pressure water, pay attention to avoid the instrument and control rod. The distance between the pressure water nozzle and the paint surface of the vehicle body shall not be less than 40 cm.
