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.

　　眾所周知，露天使用混凝土攪拌機，并且終年暴露于風，日曬雨淋。 如果定期維護和保養可以延長設備的使用壽命，讓我們介紹維修攪拌機的所有方面。

　　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.

　　混凝土攪拌機完全清潔了攪拌桶的內部和外部，排出了門等，并用水沖洗了。 未正確清潔的膠粘劑應定期清除。 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 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，每個潤滑點和變速箱是否有足夠的油脂。 觀察每個檔次電動潤滑泵的儲油缸中的潤滑脂是否用完。 用完后應及時注滿，不允許無油運行。

　　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.

　　為什么攪拌機效率低下?

　　Why is mixer inefficient?

　　1準備時間長于攪拌和排出時間。 由于準備完成后需要完成各種原材料的準備工作，因此在這種情況下，整個過程中有大量的空閑時間，并且該時間只能等待準備工作，這大大降低了每個工作流程的工作效率。 單位時間。 無法完成相應的工作量。

　　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準備時間小于或等于兩者之和。 混凝土生產過程中工作效率的計算量比較大，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. 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，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，礫石和卵石等材料由于其特殊性而難以運輸到攪拌機，因此需要花費很長時間，在這段時間內稱量水泥和固化劑以及液體并可以終止運輸，因此礫石和卵石是否 可以根據標準時間稱重和運輸，直接確定混凝土攪拌機的效率。 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，這對減少砂石運輸時間非常有利。 這些是混凝土攪拌機效率低下的原因。

　　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.
