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.

混凝土攪拌機清潔了攪拌桶的內部和外部，排干了門等，并用水沖洗了。未正確清潔的粘合劑應定期。每周擰緊攪拌葉片一次，以防止葉片墜落并引起事故。

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.

混凝土攪拌機檢查軸端密封腔，分配器的入口和出口，密封線是否光滑，是否充滿油脂以及每個潤滑點和變速箱是否有足夠的油脂。觀察各級電動潤滑泵儲油缸中的潤滑脂是否用完。使用后應及時注滿，不允許無油運行。

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.

為什么攪拌機效率低下？

Why is the mixer inefficient?

1準備時間長于攪拌和排出時間。由于各種原料的制備需要在制備完成后完成，因此在這種情況下，整個過程中有大量的空閑時間，該時間只能等待制備工作，這大大減少了工作量每個工作流程的效率。時間單位。無法完成相應的工作量。

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準備時間小于或等于兩者之和?；炷辽a過程中工作效率的計算比較大，也就是說，總生產時間過長，會破壞整個混凝土的生產平衡，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，準備階段的浪費時間太長，這意味著原料的稱量或運輸過程太長。通常，由于其特殊性，諸如礫石和卵石之類的材料很難運輸到攪拌機中，因此在這段時間內稱量水泥，固化劑和液體需要很長時間，并且可以終止運輸。

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.

因此礫石和卵石可以根據標準的時間稱量和運輸方式直接確定混凝土攪拌站的效率。在實踐中，我們可以控制稱重工具的速度，使運輸設備可以大大增加運輸工作量，對于減少砂石的運輸時間非常有利。這些是混凝土攪拌機效率低下的原因。

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.
