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

混凝土搅拌机清洁了搅拌桶的内部和外部，排干了门等，并用水冲洗了。未正确清洁的粘合剂应定期。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 cleaned the inside and outside of the mixing drum, drained the doors, etc., and washed with water. Adhesives that are not properly cleaned should be removed periodically. Tighten the mixing blade once a week to prevent the blade 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，是否充满油脂以及每个润滑点和变速箱是否有足够的油脂。观察各级电动润滑泵储油缸中的润滑脂是否用完。使用后应及时注满，不允许无油运行。

The concrete mixer shall check whether the shaft end sealing cavity, the inlet and outlet of the distributor, the sealing line are smooth and full of grease, and whether there is enough grease at each lubrication point and gearbox. Observe whether the lubricating grease in the oil storage cylinder of electric lubrication pump at all levels is used up. It shall be filled in time after use, and it is not allowed to run without oil.

为什么搅拌机效率低下？

Why is the mixer inefficient?

1准备时间长于搅拌和排出时间。由于各种原料的制备需要在制备完成后完成，因此在这种情况下，整个过程中有大量的空闲时间，该时间只能等待制备工作，这大大减少了工作量每个工作流程的效率。时间单位。无法完成相应的工作量。

1. The preparation time is longer than the mixing and discharge time. Since the preparation of various raw materials needs to be completed after the preparation, in this case, there is a lot of idle time in the whole process, which can only wait for the preparation work, which greatly reduces the workload and the efficiency of each workflow. Time unit. 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. The calculation of work efficiency in the process of concrete production is relatively large, that is, 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，由于其特殊性，诸如砾石和卵石之类的材料很难运输到搅拌机中，因此在这段时间内称量水泥，固化剂和液体需要很长时间，并且可以终止运输。

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, due to its particularity, materials such as gravel and pebble are difficult to transport to the mixer, so it takes a long time to weigh cement, curing agent and liquid during this period, and the transportation can be terminated.

因此砾石和卵石可以根据标准的时间称量和运输方式直接确定混凝土搅拌站的效率。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，对于减少砂石的运输时间非常有利。这些是混凝土搅拌机效率低下的原因。

Therefore, the efficiency of the concrete mixing plant can be directly determined according to the standard time weighing and transportation mode of gravel and pebble. 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.
