When the multi-functional mixer works, it is strictly prohibited to enter the storage area and lifting bucket; It is forbidden to put limbs into hopper and mixing bucket; When the drag shovel is stuck by obstacles, it shall not be pulled up by force, and it shall not be lifted with a shovel. Do not twist the operation of heavy objects during pulling; Do not overload the machine, check the working state of the motor, and stop immediately when the engine sound is abnormal or the temperature rises; When the mixer truck is fully loaded, in case of problems or power failure, immediately cut off the power supply, lock the switch box and clean the concrete in the mixing tank.
Before shutting down the equipment in the multi-functional mixer truck, the equipment shall be removed and then shut down in turn. The cement in the spiral pipe should be transported out. No material shall be left in the multifunctional mixer. During the freezing season, the pump and additive pump shall be drained. The water tank and additive water tank shall be started within 1-2 minutes after the start of the water pump and additive pump of the mixer truck; After the multifunctional mixer is closed, all parts of the equipment shall be cleaned and weighed.
If the oil level in the oil pump of the mixer truck is close to the oil level, we need to replenish oil. When refueling, pay attention to the absence of pressure. Clean the dust around the oil mist before operation. Cleaning to avoid entering Mr. lubricating oil is usually used for ordinary diesel engine oil. It can also use lubricating oil with viscosity of 2.5 to 7 degrees or industrial 40 engine oil. The oil in the oil cup shall be replaced in time. Generally, the capacity of the oil cup is calculated as 100 ml. The service time shall not exceed 100 hours.
Common maintenance methods, such as cleaning the filter element in the air filter, will lead to poor filtration when the filter element is too dirty and make it enter the compressor. The dust content in the air in the cylinder becomes higher, which will accelerate the wear of the cylinder and piston ring, form dirt and affect the air tightness of the valve. In severe cases, it may even lead to the pulling of cylinder and asphyxiating gas, resulting in lubricant pollution. Affect the use effect of helium, the gap between cylinder wall and piston ring is large, there is oil stain, and the polluted lubricating oil enters the compression chamber to form oil mist and pollute the compressed air.
