The concrete mixer shall provide cast-in-place concrete for the construction site in the form of centralized premixing and long-distance transportation. It is a kind of high-tech building material product, which combines modern concrete with modern construction technology. Modern buildings, highways, railways, bridges, airports and so on are inseparable from concrete pouring, so concrete mixer has become a hot product in these industries.

　　众所周知，露天使用混凝土搅拌机，并且终年暴露于风，日晒雨淋。 如果定期维护和保养可以延长设备的使用寿命，让我们介绍维修搅拌机的所有方面。

　　As is known to all, concrete mixers are used in the open air and exposed to the wind, sun and rain all year round. If regular maintenance and maintenance can prolong the service life of the equipment, let's introduce all aspects of repairing the mixer.

　　混凝土搅拌机完全清洁了搅拌桶的内部和外部，排出了门等，并用水冲洗了。 未正确清洁的胶粘剂应定期。 每周拧紧搅拌叶片一次，以防止叶片坠落并引起事故。

　　The concrete mixer completely cleaned the inside and outside of the mixing bucket, discharged the door, etc., and washed it with water. Adhesives that are not properly cleaned should be removed periodically. Tighten the mixing blades once a week to prevent the blades from falling and causing accidents.

　　混凝土搅拌机检查轴端密封腔，分配器的入口和出口，密封线是否光滑，是否充满油脂，每个润滑点和变速箱是否有足够的油脂。 观察每个档次电动润滑泵的储油缸中的润滑脂是否用完。 用完后应及时注满，不允许无油运行。

　　The concrete mixer shall check the sealing cavity at the shaft end, the inlet and outlet of the distributor, whether the sealing line is smooth and full of grease, and whether there is enough grease at each lubricating point and gearbox. Observe whether the grease in the oil reservoir of each grade of electric lubricating pump is used up. After use, it should be filled in time, and no oil-free operation is allowed.

　　为什么搅拌机效率低下?

　　Why is mixer inefficient?

　　1准备时间长于搅拌和排出时间。 由于准备完成后需要完成各种原材料的准备工作，因此在这种情况下，整个过程中有大量的空闲时间，并且该时间只能等待准备工作，这大大降低了每个工作流程的工作效率。 单位时间。 无法完成相应的工作量。

　　The preparation time is longer than the mixing and discharging time. Due to the need to complete the preparation of various raw materials after preparation, so in this case, there is a lot of idle time in the whole process, and this time can only wait for the preparation work, which greatly reduces the work efficiency of each workflow. Unit time. Unable to complete the corresponding workload.

　　2准备时间小于或等于两者之和。 混凝土生产过程中工作效率的计算量比较大，也就是说，总生产时间过长，会破坏整个混凝土的生产平衡，工作效率低。

　　2. The preparation time is less than or equal to the sum of the two. In the process of concrete production, the calculation of work efficiency is relatively large, that is to say, if the total production time is too long, the production balance of the whole concrete will be destroyed, and the work efficiency will be low.

　　通常，准备阶段的浪费时间太长，这意味着原料的称量或运输过程太长。 通常，砾石和卵石等材料由于其特殊性而难以运输到搅拌机，因此需要花费很长时间，在这段时间内称量水泥和固化剂以及液体并可以终止运输，因此砾石和卵石是否 可以根据标准时间称重和运输，直接确定混凝土搅拌机的效率。 在实践中，我们可以控制称重工具的速度，使运输设备可以大大增加运输工作量，这对减少砂石运输时间非常有利。 这些是混凝土搅拌机效率低下的原因。

　　Usually, the waste time in the preparation stage is too long, which means that the weighing or transportation process of raw materials is too long. Generally, gravel and pebble and other materials are difficult to transport to the mixer due to their particularity, so it takes a long time to weigh cement, curing agent and liquid during this period, and the transportation can be terminated. Therefore, whether gravel and pebble can be weighed and transported according to the standard time can directly determine the efficiency of concrete mixer. In practice, we can control the speed of weighing tools, so that the transportation equipment can greatly increase the transportation workload, which is very beneficial to reduce the transportation time of sand and gravel. These are the reasons for the low efficiency of concrete mixer.
