混凝土攪拌車設備在長時間的使用中難免會存在一定的故障問題，為了避免設備在使用中的良好性能，就需要我們對設備進行合理的維修才行。那么設備在維修過程中存在哪些需要注意的事項呢？下面小編為您解答。

It is inevitable that the concrete mixer equipment will have some problems in the long-term use. In order to avoid the good performance of the equipment in use, we need to carry out reasonable maintenance on the equipment. What should be paid attention to during equipment maintenance? The following section will answer your question.

1、攪拌筒：在初次使用到50小時時，要及時檢查罐體及其他部位螺栓是否有松動，每天行車前要檢查托輪與滾道的潤滑，每個月打開一次托輪護罩，清理內部的油污并添加潤滑油脂。

1. Mixing drum: when the tank and other parts are used for 50 hours for the first time, timely check whether the bolts of the tank and other parts are loose. Before driving every day, check the lubrication of the supporting wheel and the raceway. Open the supporting wheel shield once a month, clean the internal oil stain and add lubricating grease.

2、液壓驅動系統(tǒng)：液壓系統(tǒng)是攪拌車的核心系統(tǒng)。為保證攪拌車能正常工作，攪拌罐能運轉正常，須在每次車輛發(fā)動前檢查油路散熱器和減速機的液壓油位，保證油位指示在視窗范圍內。同時要保證它的清潔，不能讓灰塵等污染系統(tǒng)液壓油，造成系統(tǒng)不能正常工作或損壞。

2. Hydraulic drive system: the hydraulic system is the core system of the mixer. In order to ensure that the mixer truck can work normally and the mixing tank can operate normally, the hydraulic oil level of the oil radiator and reducer must be checked each time before the vehicle is started to ensure that the oil level indication is within the scope of the window. At the same time, ensure that it is clean, and do not allow dust and other pollutants to pollute the hydraulic oil of the system, causing the system to not work normally or be damaged.

3、供水系統(tǒng)：氣壓供水系統(tǒng)加水量好在水箱的四分之三處，經常檢查閥體是否堵塞或是否有工作異常。在有結冰可能的環(huán)境中使用時，供水系統(tǒng)須排空存水，防止管路凍裂。

3. Water supply system: air pressure water supply system can add water at three quarters of the water tank. Check the valve body frequently for blockage or abnormal operation. When the water supply system is used in an environment with the possibility of icing, the water storage must be drained to prevent the pipeline from freezing.

不能夠給混凝土攪拌車的輪胎栓螺母涂油，不少司機認為給輪胎栓螺母涂潤滑油能夠避免螺栓螺母生銹，事實上，這種做法是非常危險的，因為它會給攪拌車行車帶來隱患。螺栓和螺母擰緊之后本身是有自鎖特點的，而潤滑油則會讓自鎖系數(shù)下降。攪拌罐運作過程中，螺栓螺母一旦松動就會產生事故。

It is not allowed to oil the tire bolts and nuts of the concrete mixer. Many drivers think that coating the tire bolts and nuts with lubricating oil can prevent the bolts and nuts from rusting. In fact, this practice is very dangerous, because it will bring hidden dangers to the driving of the mixer. Bolts and nuts have self-locking characteristics after being tightened, while lubricating oil will reduce the self-locking coefficient. During the operation of the mixing tank, once the bolts and nuts are loosened, accidents will occur.

不能用水直接沖洗小型混凝土攪拌車車身，攪拌罐車身內部機構是比較復雜的，凹槽、通孔設計比較多，一旦用水沖洗了，那么水分沉積在機身內不容易干燥，就容易使得零部件銹蝕。

It is not allowed to directly wash the body of a small concrete mixer truck with water. The internal mechanism of the mixing tank body is relatively complex, and there are many grooves and through-hole designs. Once washed with water, the moisture deposited in the body is not easy to dry, and the parts are easy to rust.

除了上述這些知識內容外，經常性的檢查混凝土攪拌車系統(tǒng)的密封性，拆卸修理后，關鍵部位要涂螺紋密封膠車輛在行駛時水路系統(tǒng)中各個閥門均應處于關閉狀態(tài)，以免影響車輛的制動性能。

In addition to the above knowledge, check the tightness of the concrete mixer system frequently. After disassembly and repair, apply thread sealant on key parts. All valves in the waterway system should be closed when the vehicle is running, so as not to affect the braking performance of the vehicle.
