As a transport vehicle, self loading mixer must comply with the maintenance and repair regulations of the Ministry of communications. Combined with the actual situation of concrete mixer, maintenance and repair are carried out. In terms of daily maintenance, in addition to the maintenance of the self loading mixer engine and chassis, the following maintenance work must be carried out for the self loading mixer.

一，合理確定保護周期：自上料攪拌車保護周期是指汽車保護的距離或時間。在實際應用過程中，車主應參考汽車制造商介紹的保護周期，聯系汽車自身的技術和應用前提，并對保護周期進行適當調整。一般來說，新車在優越路況的前提下使用，沒有必要過于頻繁地保護，并且制造商規則的保護周期可以作為上限。如果汽車技能差，或前提不好，應適當縮短保護周期。

1、 Reasonably determine the protection period: the protection period of self loading mixer refers to the distance or time of vehicle protection. In the process of practical application, the owner should refer to the protection period introduced by the automobile manufacturer, contact the technology and application premise of the vehicle itself, and adjust the protection period appropriately. Generally speaking, it is not necessary to protect new cars too frequently when they are used under the premise of superior road conditions, and the protection period specified by the manufacturer can be used as the upper limit. If the vehicle skill is poor or the premise is not good, the protection period should be appropriately shortened.

二，免費測試的充分應用：自上料攪拌車制造商的自由檢測運動往往有利于車主的長度，車主可以應用這些測試活動對車進行特定的體檢，找出并消除一些潛在的問題實時，然后節省需求可以在將來呈現的高維護和保護成本。

2、 The full application of free testing: the free inspection campaign from the manufacturer of the loading mixer is often beneficial to the length of the owner. The owner can use these testing activities to carry out specific physical examination on the vehicle, find and eliminate some potential problems in real time, and then save the high maintenance and protection costs that can be presented in the future.

三，盡可能坍塌的修理組件：很多自上料攪拌車的擁有者都有這種感覺，就像汽車組件在坍塌后的維修將是不可阻擋的，這樣車輛進入維修期太早。這種場景的原因是首先要了解修理工的裝配技巧和質量。因此，最好是防止碰撞修復組件，應用各種類型的先進技能保護裝備和技巧，保護自上料攪拌車免于拆卸，防止損壞自上料攪拌車組件和部件，提高保護質量，進而減少維護總成本。

3、 Repair components that collapse as much as possible: many owners of self loading mixers have this feeling, just like the repair of automobile components after collapse will be unstoppable, so the vehicle enters the maintenance period too early. The reason for this scenario is to first understand the assembly skills and quality of the repairman. Therefore, it is better to prevent collision and repair components, apply various types of advanced skills to protect equipment and skills, protect self loading mixer from disassembly, prevent damage to components and parts of self loading mixer, improve protection quality, and reduce total maintenance cost.

除了上述知識之外，在通過混凝土攪拌輸送混凝土之后，通常用水清洗混合筒的內部以防止硬化的混凝土占據空間，并且混合筒的體積越來越小。設備的合理運行和維護工作可以有效地防止設備在施工過程中的良好性能。

In addition to the above knowledge, after conveying concrete through concrete mixing, the interior of the mixing cylinder is usually cleaned with water to prevent hardened concrete from occupying space, and the volume of mixing cylinder is getting smaller and smaller. The reasonable operation and maintenance of the equipment can effectively prevent the good performance of the equipment in the construction process.
