1、根据减水剂的用量或减水率利用率高的减水剂,选择适应性好的减水剂和混凝土类型。提高砂石配合比,找到砂石配合比对各砂浆配合比,提高和易性,从而减少用水量。
1. According to the dosage of water reducing agent or the water reducing agent with high water reducing efficiency, the water reducing agent and concrete type with good adaptability shall be selected. Increase the sand and stone mix proportion, find the sand and stone mix proportion of each mortar mix proportion, improve the workability and reduce the water consumption.
2、要严格检验每种材料的性能,控制以上要素,减少用水量。通过使用大量水泥材料来提高可加工性。多检查砂石含水量,提高责任心,确保混凝土坍落度在每次出料率的控制范围内。水泥自上料搅拌机
2. Strictly inspect the performance of each material, control the above factors and reduce water consumption. Improve workability by using a large amount of cement materials. Check the water content of sand and stone more, improve the sense of responsibility, and ensure that the concrete slump is within the control range of each discharge rate. Cement self feeding mixer
3、与水泥自上料搅拌机施工现场施工单位的沟通非常重要。要想得到施工队的了解,需要配合施工单位方法人员,防止过度坍落度。恰当的概念:并不是坍落度越大,水下混凝土越容易,而是要调整和易性和砂石的用量。这都是非常合理的,并且很可能控制搅拌设备的用水量。大家在实际操作中一定要小心,防止放纵水源。
3. It is very important to communicate with the construction unit at the construction site of the cement self feeding mixer. To get the understanding of the construction team, it is necessary to cooperate with the method personnel of the construction unit to prevent excessive slump. Proper concept: it is not that the greater the slump, the easier the underwater concrete is, but that the workability and the amount of sand and gravel should be adjusted. This is very reasonable, and it is likely to control the water consumption of the mixing equipment. We must be careful in actual operation to prevent the indulgence of water sources

Method for controlling water consumption of cement self feeding mixer equipment
此外清洗水泥自上料搅拌机的水箱也是不能忽视的,可以这样做:
In addition, cleaning the water tank of the cement self feeding mixer can not be ignored. This can be done:
装车后,用清水冲洗进水口,将进水口附近剩余的混凝土清洗干净,防止运输后干燥后的混凝土吸附在进水口上。干燥的混凝土不容易清洗。每次运输混凝土时,进料口都要用水冲洗,以保持装载的混凝土入口湿润。在工地卸料后,及时用自带的清洗水冲洗卸料槽,然后在混凝土储罐中加入一些清水,保证车辆返回时混凝土储罐缓慢转动。
After loading, wash the water inlet with clean water to clean the remaining concrete near the water inlet to prevent the dried concrete from being adsorbed on the water inlet after transportation. Dry concrete is not easy to clean. Each time the concrete is transported, the feed inlet shall be flushed with water to keep the loaded concrete inlet wet. After unloading at the construction site, wash the unloading tank with its own cleaning water in time, and then add some clean water to the concrete storage tank to ensure that the concrete storage tank rotates slowly when the vehicle returns.
及时将水箱内的混凝土残渣擦干,防止混凝土吸附在水箱内壁上。当它到达搅拌站并重新填充混凝土时,将水箱中的清水排出并重复相同的步骤。将混凝土输送到罐体和进料口时,避免混凝土吸附;装砼时,不要偷懒,将随车自带的洗车水箱灌满洗车水不加水。
Wipe the concrete residue in the water tank in time to prevent the concrete from being adsorbed on the inner wall of the water tank. When it arrives at the mixing plant and refills the concrete, first drain the clean water from the water tank and repeat the same steps. When the concrete is transported to the tank body and feed inlet, avoid the adsorption of concrete; When loading concrete, do not be lazy. Fill the car washing water tank with car washing water instead of adding water.
