The automatic feeding cement mixer is a mechanical equipment widely used in urban construction roads, rural road construction, bridges, houses, water conservancy projects, infrastructure projects, mixing stations and other projects. Especially in recent years, the rapid development of rural areas in China provides space for the development of automatic feeding cement mixers. With its advantages of fast and high efficiency, the equipment occupies the core of concrete construction projects. Today, what Fred taught you from the concrete mixer factory is the operation precautions of the automatic feeding cement mixer. I hope you can read it carefully.
2. After the engine of the automatic feeding cement mixer is started, the mixing drum shall be rotated at low speed for about 10 minutes to make the hydraulic oil temperature rise to above 20 ℃ before operation.
3. When transporting concrete, the automatic loading cement mixer shall ensure that the sliding bucket is firmly placed to prevent swinging due to looseness, injuring pedestrians or affecting the normal operation of other vehicles.
5. When the automatic loading cement mixer truck is used to transport the mixed concrete, the rotating speed of the mixing drum is 2-10 rpm. During the transportation, the rotating speed of the mixing drum on the flat road shall be guaranteed to be 2-3 rpm. When driving on the road with a side slope greater than 50, or the road with a large shake from left to right, the mixing rotation shall be stopped, and the mixing rotation shall be resumed after the road conditions improve.
6. The time for automatic loading cement mixer to transport concrete shall not exceed the time specified by the mixing station. During the transportation of concrete, the mixing drum shall not be stopped for a long time to prevent segregation of concrete. The driver shall always observe the concrete condition, report to the dispatching room in time in case of any abnormality, and apply for handling.
7. The slump of concrete transported by automatic feeding mixer shall not be less than 8cm. From the time of concrete entering the tank to discharging, it shall not exceed 2 hours when the temperature is high, and it shall not exceed 2.5 hours when the temperature is low in rainy days.
8. Before discharging the concrete, the automatic loading cement mixer shall rotate the mixing drum for 1 minute at the speed of 10-12 rpm before discharging.
9. After discharging, immediately flush the feeding inlet, discharge hopper, discharge chute and other parts with the hose attached to the vehicle, drain the dirt and residual concrete bonded to the vehicle body, and then inject 150-200L clean water into the mixing drum. On the way back, let the mixing drum rotate slowly to clean the inner wall to avoid the residual slag adhering to the drum wall and mixing blade, and drain the water before re loading.
10. When the automatic feeding cement mixer is used to transport concrete, the engine speed shall be within the range of 1000-1400 rpm to make the engine have a large torque. During the concrete transportation, the speed shall not exceed 40km/h to ensure driving.
11. When the water pump of the automatic feeding cement mixer is working, it is prohibited to idle, and the continuous use shall not exceed 15 minutes.
In addition, the manufacturer of the loading concrete mixer reminds everyone that after the automatic loading cement mixer is completed, the inside and body of the mixing drum should be cleaned in time, and the remaining concrete should not be left in the drum.
