When the small automatic concrete mixer is working, it is strictly forbidden to enter the storage area and lifting bucket; It is strictly forbidden to put limbs into hopper and mixing bucket; When the dragline is stuck by obstacles, it should not be pulled up by force, and it should not be lifted up by shovel. Do not twist the weight during pulling; Don't overload the machine. Check the working state of the motor. When the engine sounds abnormal or the temperature rises, stop immediately; When the automatic concrete mixer is fully loaded, if there is a problem or power failure, immediately cut off the power supply, lock the switch box and clean the concrete in the mixing tank.

在关闭混凝土搅拌机中的设备之前，应先拆除设备，然后依次关闭。螺旋管中的水泥应该运出来。小型混凝土自动搅拌机中不应留有任何材料。在冷冻季节，泵和添加剂泵应排干。水箱和添加水箱应在混凝土搅拌机水泵和添加剂泵启动后1-2分钟内启动;混凝土搅拌机关闭后，设备的各部分应清洗干净，并保证称重。

Before shutting down the equipment in the concrete mixer, the equipment shall be removed first and then shut down in turn. The cement in the spiral pipe should be transported out. There should be no material left in the small automatic concrete mixer. During the freezing season, pumps and additive pumps should be drained. The water tank and adding water tank shall be started within 1-2 minutes after the concrete mixer water pump and additive pump are started; After the concrete mixer is closed, all parts of the equipment shall be cleaned and weighed.

如果混凝土搅拌机的油泵中的油位接近油位，我们需要补充油。加油时，要注意没有压力的情况。操作前清洁油雾周围的灰尘。清洁以避免进入先生润滑油通常用于普通柴油发动机油。它还可以使用粘度为2.57度的润滑油或工业40＃发动机油。储油杯中的油应及时更换。通常，油杯容量计算为100毫升。使用时间不应超过100小时。

If the oil level in the pump of the concrete mixer is close to the oil level, we need to replenish the oil. When refueling, pay attention to the situation without pressure. Clean the dust around the oil mist before operation. Clean to avoid entering Mr. lubricating oil is usually used for ordinary diesel engine oils. It can also use lubricants with viscosities of 2.5 to 7 degrees or industrial 40 engine oil. The oil in the oil cup should be changed in time. Generally, the capacity of the oil cup is calculated as 100 ml. The use time should not exceed 100 hours.

常见的维护方法，例如清洁空气过滤器中的过滤器元件，会导致过滤器元件过脏时过滤不好，使其进入压缩机。气缸内空气中的灰尘含量变高，会加速气缸和活塞环的磨损，形成污垢，影响气门的气密性。在严重的情况下，它甚可能导致汽缸和窒息气体的拉动，导致润滑剂污染。影响氦气的使用效果等，气缸壁与活塞环之间的间隙大，有油污，污染的润滑油进入压缩室形成油雾，污染压缩空气。

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 higher the dust content in the air in the cylinder 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 cylinder and suffocating gas pulling, leading to lubricant contamination. The gap between the cylinder wall and the piston ring is large and there is oil stain. The polluted lubricating oil enters the compression chamber to form oil mist and pollute the compressed air.
