搅拌设备的使用性能现在所展现出来的性能,与在冬季温度相对比较低的情况下是不相同的。首先就是使用的水泥原材料因为其中含有的水分,在低温下容易成冰,并且将会影响到搅拌设备的正常使用。
The performance of mixing equipment is different from that in winter when the temperature is relatively low. The first is the use of cement raw materials, because of the moisture contained in them, it is easy to form ice at low temperature, and will affect the normal use of mixing equipment.
环境温度低使用的水泥的水化反应慢,影响搅拌设备强度的增长。试验得出:温度每降低1℃ ,水泥的水化作用降低约5 %~ 7%,在1℃~0℃ 范围内水泥的水化活性剧烈地降低,水化作用缓慢。拌机性能影响一般当温度低于0℃ 的某个范围时,游离水将开始结冰,温度低到一定程度时,游离水几乎全部冻结成冰,致使水泥的水化和硬化完全停止。但是当水转化为固态的冰时,它的体积约增大9%,使混凝土产生内应力,温度对混凝搅造成骨料与水泥颗粒的相对位移及内部水分向负温表面迁移,在混凝土体内形成冰聚体引起局部结构破坏。
The hydration reaction of cement used in low ambient temperature is slow, which affects the strength growth of mixing equipment. The results show that the hydration of cement decreases by 5% ~ 7% when the temperature decreases by 1 ℃. The hydration activity of cement decreases sharply in the range of 1 ℃~ 0 ℃, and the hydration action is slow. Generally speaking, when the temperature is below a certain range of 0 ℃, the free water will start to freeze. When the temperature is low to a certain extent, the free water almost freezes into ice, resulting in the complete stop of hydration and hardening of cement. However, when water is transformed into solid ice, its volume increases by about 9%, which makes the concrete produce internal stress. The temperature causes the relative displacement of aggregate and cement particles and the internal moisture migrates to the negative temperature surface, forming ice aggregates in the concrete body and causing local structural damage.
但是使用的新浇筑的混凝土过早遭受冻结将大大降低极限强度,并且强度损失率可能达到设计标号的50%,甚至引起整体结构破坏;但当混凝土达到临界强度后遭受冻结,混凝土的极限强度损失较小,也不会发生整体结构破坏。其冰点的降低幅度与防冻剂的种类和掺量或溶液的浓度有关。防冻剂的使用效果在很大程度上取决于溶液的浓度以及混凝土硬化过程经受的负温值。
However, the early freezing of the newly poured concrete will greatly reduce the ultimate strength, and the strength loss rate may reach 50% of the design grade, and even cause the overall structure damage; but when the concrete reaches the critical strength, the ultimate strength loss of the concrete is small, and the overall structure damage will not occur. The decreasing range of freezing point is related to the type and content of antifreeze or the concentration of solution. The effect of antifreeze depends largely on the concentration of solution and the negative temperature value of concrete during hardening.

因为在这样特殊的温度下对搅拌设备性能有一定的影响,所以一般施工将不会选择在这种情况下进行,因为不仅影响到材料的使用情况,更是会影响施工的正常效果。
Because in such a special temperature on the performance of mixing equipment has a certain impact, so the general construction will not be selected in this case, because it will not only affect the use of materials, but also affect the normal effect of construction.
1、为避免搅拌机械轴套内的型圈在装置时被损坏所以首要要用生料带将卡簧槽填满,然后再将轴套与动环座一同套入并用专用管子均匀击打到位,然后再将卡簧取下;
1. In order to avoid damage to the ring in the shaft sleeve of the mixing machine during the installation, it is necessary to fill the snap ring groove with the raw material belt first, then insert the shaft sleeve and the moving ring seat together, and hit them in place with a special pipe, and then remove the snap ring;
2、装置动环0型圈之后需求再将动环装上,这儿需求留意装置动环时要对准凹凸点而且要求一起进入;
2. After the installation of moving ring 0-ring, it is required to install the moving ring again. Here, it is necessary to pay attention to the concave convex point when installing the moving ring, and it is required to enter together;
3、将搅拌机械的静环装置到位后要使静环0型圈进入搅拌机械机体并卡上轴套卡簧;
3. After the static ring device of the mixing machine is in place, make the 0-ring of the static ring enter into the mixing machine body and clamp the shaft sleeve clasp;
4、将静环压盘装上再将轴架反向套入,之后用专用的螺栓固定住,然后挑选用管钳逆时针方向旋转而且慢慢地将轴压入到位,再紧固静环压盘即可;
4. Install the static ring pressure plate, then insert the shaft bracket in the opposite direction, fix it with special bolts, and then select the pipe tongs to rotate anticlockwise and slowly press the shaft into place, and then fasten the static ring pressure plate;
5、撤除轴架之后从头正向、受力均匀装置轴架,然后将后盖给装上,搅拌机械更换机封的作业就完成了。
5. After removing the shaft frame, the shaft frame is installed in the positive direction from the beginning and evenly stressed, and then the back cover is installed, and the operation of replacing the mechanical seal of the mixing machine is completed.
