1、 First of all, the tank of automatic feeding mixing tank should be maintained. After each concrete transportation and entering the cleaning tank, it is necessary to understand that the concrete is very easy to bond with steel.

二、放料的均匀性问题是自动上料搅拌罐的一个关键指标值之一,它直接干扰着施工质量。在运送混凝土时,搅匀筒转速比应控制在2~5r/min,在运送间距较长也许 混凝土的塌落度比较大时,放料前要先将搅匀筒迅速移动5~10圈,使里面的混凝土能充分搅匀,那样放料的均匀性便会进一步提高。若中途混凝缺水,到工地应兑水调节,并充分搅匀,尽管这类环境应只要制止,可是那样会使混凝土的品质无法得到保证。有的客户在运用时不注意控制在运送过程中的转速比,过快会增.大燃油的损耗,过小则会导致混凝土离析。因而应严苛根据要求来控制搅匀筒的转速比,以提升混凝土运送品质。

2、 The uniformity of discharging is one of the key indexes of automatic feeding mixing tank, which directly affects the construction quality. When transporting concrete, the rotating speed ratio of mixing cylinder should be controlled at 2 ~ 5R / min. when the transportation distance is long and the slump of concrete is relatively large, the mixing cylinder should be moved 5 ~ 10 circles before placing materials to make the concrete inside can be fully mixed, so that the uniformity of discharging will be further improved. If there is water shortage in the process of coagulation, water should be added to the construction site for adjustment and mixing. Although such environment should be stopped, the quality of concrete can not be guaranteed. Some customers do not pay attention to control the speed ratio in the process of transportation. If it is too fast, it will increase. If the fuel consumption is too small, it will lead to concrete segregation. Therefore, the speed ratio of mixing drum should be controlled strictly according to the requirements to improve the quality of concrete transportation.

三、凝土较大限定不可以高出储罐的较大方量,是因为混凝土强度等级区别它的密度也区别,高强度混凝土一般密度也大,一样的容积,装多了对车不好。输送混凝土的容积、品质及坍落度应契合车辆运用使用说明书中的要求,实时加注润滑油。

3、 The larger limit of concrete can not be higher than the larger volume of storage tank, because the strength grade of concrete is different, and the density of high-strength concrete is also different. Generally, the density of high-strength concrete is large, and the same volume is not good for vehicles. The volume, quality and slump of transported concrete shall meet the requirements of vehicle operation manual, and lubricating oil shall be added in real time.

四、露天停放过的自动上料搅拌罐,装料前要先将搅匀筒以放料偏向旋转,把水泥罐内的积水放掉,确保运送混凝土的品质。

4、 For the automatic feeding mixing tank which has been parked in the open air, the mixing drum should be rotated to discharge the water in the cement tank before loading, so as to ensure the quality of concrete transported.
